Effect of oestradiol on dopamine receptors and protein kinase C activity in the rat pituitary: binding of oestradiol to pituitary membranes.
Joubert-Bression D, Brandi AM, Birman P, Peillon F.
INSERM U 223, Faculte de Medecine Pitie-Salpetriere, Paris, France.
Oestradiol exerts an important modulatory influence on the release of prolactin which is accomplished partly through disruption of the inhibitory influence of dopamine. We have focused on the status of the anterior pituitary D2 dopamine receptor in female rats treated chronically with oestradiol or progesterone. A direct membrane effect of these steroids on the dopamine system was also investigated in vitro. Both steroids affected the status of the D2 receptor, oestradiol decreasing the number of sites in vitro and progesterone increasing it both in vitro and in vivo. The in vitro studies demonstrated that these steroids exert a direct membrane effect on the D2 receptor. These results correlated with an in vitro short-term physiological effect of oestradiol and progesterone on the dopaminergic inhibition of prolactin release, oestradiol decreasing it while progesterone had the opposite effect. Binding studies with [3H] oestradiol on pituitary membranes revealed a site for oestradiol of high affinity and low capacity, indicating that oestradiol's membrane effects could be mediated by a specific receptor. In vivo treatment with oestradiol also induces proliferation of prolactin-secreting cells (lactotrophs). We focused on the effect of oestradiol on protein kinase C activity, which is involved in both secretion and proliferation. In female rats treated with oestradiol total protein kinase C activity was increased by 74% (particulate 90%, soluble 71%) in comparison with controls. This effect was reversed by concomitant treatment with a dopamine agonist. Thus in the pituitary oestradiol and progesterone affect the characteristics of membrane components that are implicated in the physiological control of the cell. Whether these effects are post-transcriptional only or are also mediated through direct membrane mechanisms needs further investigation.

Vitamin D(3) attenuates 6-hydroxydopamine-induced neurotoxicity in rats.
Wang JY, Wu JN, Cherng TL, Hoffer BJ, Chen HH, Borlongan CV, Wang Y.
Department of Physiology, National Defense Medical Center, Taipei, Taiwan.
Previous reports have demonstrated that exogeneous administration of glial cell line-derived neurotrophic factor (GDNF) reduces ventral mesencephalic (VM) dopaminergic (DA) neuron damage induced by 6-hydroxydopamine (6-OHDA) lesioning in rats. Recent studies have shown that 1,25-dihydroxyvitamin D(3) (D3) enhances endogenous GDNF expression in vitro and in vivo. The purpose of present study was to investigate if administration of D3 in vivo and in vitro would protect against 6-OHDA-induced DA neuron injury. Adult male Sprague-Dawley rats were injected daily with D3 or with saline for 8 days and then lesioned unilaterally with 6-OHDA into the medial forebrain bundle. Locomotor activity was measured using automated activity chambers. We found that unilateral 6-OHDA lesioning reduced locomotor activity in saline-pretreated animals. Pretreatment with D3 for 8 days significantly restored locomotor activity in the lesioned animals. All animals were sacrificed for neurochemical analysis 6 weeks after lesioning. We found that 6-OHDA administration significantly reduced dopamine (DA), 3,4-dihydroxy-phenylacetic acid (DOPAC) and homovanilic acid (HVA) levels in the substantia nigra (SN) on the lesioned side in the saline-treated rats. D3 pretreatment protected against 6-OHDA-mediated depletion of DA and its metabolites in SN. Using primary cultures obtained from the VM of rat embryos, we found that 6-OHDA or H(2)O(2) alone caused significant cell death. Pretreatment with D3 (10(-10) M) protected VM neurons against 6-OHDA- or H(2)O(2)-induced cell death in vitro. Taken together, our data indicate that D3 pretreatment attenuates the hypokinesia and DA neuronal toxicity induced by 6-OHDA. Since both H(2)O(2) and 6-OHDA may injure cells via free radical and reactive oxygen species, the neuroprotection seen here may operate via a reversal of such a toxic mechanism.
Protective effects of 1 alpha,25-(OH)(2)D(3) against the neurotoxicity of glutamate and reactive oxygen species in mesencephalic culture.Ibi M, Sawada H, Nakanishi M, Kume T, Katsuki H, Kaneko S, Shimohama S, Akaike A.
Department of Pharmacology, Graduate School of Pharmaceutical Sciences, Kyoto University, Sakyo-ku, Kyoto 606-8501, Japan.
This study was undertaken to determine whether 1 alpha,25-dihydroxyvitamin D3 [1 alpha,25-(OH)(2)D(3)], an active metabolite of vitamin D, protects dopaminergic neurons against the neurotoxic effects of glutamate and dopaminergic toxins using rat mesecephalic culture. Brief glutamate exposure elicited cytotoxicity in both dopaminergic and non-dopaminergic neurons. Pretreatment, but not co-administration, of 1 alpha,25-(OH)(2)D(3) protected both types of neurons against the cytotoxicity of glutamate in a concentration- and time-dependent manner. The neuroprotective effect of 1 alpha,25-(OH)(2)D(3) was inhibited by the protein synthesis inhibitor, cycloheximide. To investigate the mechanisms of these neuroprotective effects, we examined the effects of 1 alpha,25-(OH)(2)D(3) on neurotoxicity induced by calcium ionophore and reactive oxygen species (ROS). Pretreatment with 1 alpha,25-(OH)(2)D(3) protected both types of neurons against the cytotoxicity induced by A23187 in a concentration-dependent manner. Furthermore, 24-h pretreatment with 1 alpha,25-(OH)(2)D(3) concentration-dependently protected both types of neurons from ROS-induced cytotoxicity. A 24-h incubation with 1 alpha,25-(OH)(2)D(3) inhibited the increase in intracellular ROS level following H(2)O(2) exposure. A 24-h exposure to 1-methyl-4-phenylpyridium ion (MPP(+)) or 6-hydroxydopamine (6-OHDA) exerted selective neurotoxicity on dopaminergic neurons, and these neurotoxic effects were ameliorated by 1 alpha,25-(OH)(2)D(3). These results suggest that 1 alpha,25-(OH)(2)D(3) provides protection of dopaminergic neurons against cytotoxicity induced by glutamate and dopaminergic toxins by facilitating cellular functions that reduce oxidative stress.

Thanks Ray, that is all very fascinating. Your posts aren't confusing. I am just trying to process the vast amount of information I get here with less-than-usual mental faculties...
The reason I perked up at your last post here was the mention of chocolate and salami. I had just a few days ago told Kara about chocolate being my mood "cure-all". And, one thing that I never really understood was my cravings for salami, summer sausage, etc. I just chalked that one up to being drawn to wrong foods.
Something you mentioned in your post to me that I find interesting was "the body can make PEA from phenylalanine, via phenylalanine decarboxylase (magnesium + p5p)". Oddly enough, I was very deficient in both magnesium and B6 and I believe I must still be to some degree (I have symptoms again within a day or two of missing my supplements).
I am going to go out on a limb and ask you a question that may seem really dumb to you. Right now I am digging through my memory archives to place where I have heard "phenylalanine" a lot in the past. Is that in over-the-counter diet pills? (Sorry if I am way off.)
You mentioned viruses also. Whenever I run a low-grade fever I have mental symptoms (depression, anxiety, brain fog...). I am going through that right now in fact. I just associated the mental symptoms with the fever and not so much with the cause of the fever. Now I am rethinking things... The first time I noticed this connection was when I had a severe case of mono 25 years ago (now 43). Do you think that this same virus could remain dormant in my body for this long and pop up every so often causing ugly mental symptoms? Hmmm...
Thanks again,
Simus

I am very sensitive to glutamates. Do you think that this could be a vitamin D deficiency? Well, at least it sounds like D would prevent damage caused by glutamates, huh?
Is "1 alpha,25-dihydroxyvitamin D3 [1 alpha,25-(OH)(2)D(3)]" found in the typical vitamin D, or is there a specific form of D or D complex I would need to buy?
Thanks for your patience.

retinoic acid inhibiting TSH is interesting, particularly as hypothyroid people don't activate vitamin A easily.
Retinoic acid inhibits in vivo thyroid-stimulating hormone secretion.
Coya R, Carro E, Mallo F, Dieguez C.
Department of Physiology, Faculty of Medicine, University of Santiago de Compostela, Spain.
Retinoids are needed for normal growth and development. Retinoic acid (RA), an active metabolite of vitamin A, acts through nuclear receptors that belongs to the superfamily which also includes the T3 receptors and 1-25-dihydroxyvitamin D receptor. In order to assess whether RA is a regulator of in vivo thyroid-stimulating hormone (TSH) secretion, we studied the effect of RA administration on spontaneous basal TSH secretion and TSH responses to TRH in either euthyroid or hypothyroid rats. We found that rats treated with RA showed a decrease in spontaneous basal TSH levels and TSH responses to TRH. Similarly, RA administration to hypothyroid rats led to a decrease on TSH responses to TRH. Our data suggests that RA plays an important inhibitory role on in vivo secretion and this effect is unrelated to the thyroid status of the animals.

> I am very sensitive to glutamates. Do you think that this could be a vitamin D deficiency? Well, at least it sounds like D would prevent damage caused by glutamates, huh?Think there's several reasons for glutamate sensitivity (magnesium + zinc + B6 deficiency, inflammation, heavy metal toxicity, lipid peroxidation, infection, low pH, alcohol...and sure there's others!) and vitamin D can help in some people - I find I have to take vitamin A at the same time from a fish oil source. Vitamin D is in cod liver oil, but not in sufficient quantities for a reasonable deficiency.

maybe this was why i needed vitamin A and D together...if vitamin D upregulates TSH, then maybe I needed vitamin A to downregulate it?
TSH secretion stimulated by thyroliberin in patients with hypothyroidism receiving 1,25-hydroxyvitamin D3]
[Article in Polish]
Gasinska T, Kierat A, Kochanska-Dziurowicz A, Izbicka M.
I Klinika Chorob Wewnetrznych Slaskiej AM, Katowicach.
The effect of 1,25-hydroxy vitamin D3 on the secretion of TSH was studied in 49 patients with primary hypothyroidism. The vitamin D3 metabolite did not cause any significant changes in the secretion of TSH both basal and stimulated with TRH in patients with untreated hypothyroidism. In those treated with the synthetic L-thyroxine it produced a significant increase in basal TSH secretion.

Thanks for all the info, Ray! You are a blessing.
Do you mind if I ask if you are on meds, and if so, which ones? Also, would you mind sharing what your diagnosis was? You obviously don't have to, and if you don't want to, I would certainly understand. But I would guess you and Kara and I have some similar things happening here...
God bless,

>Interesting Ray.
I would not have been surprised if you'd found VitD plays an important inhibitory role on TSH responses to TRH.
Logic here being on hotter days( supposedly stronger VitD in sun) you seem to need less T3..which also makes sense as you don't require as much energy to maintain body temperature at 37C..not that I ever get there!Nah, VItD and temperature are tooooo far unrelated. I wonder how temperature regulates TSH?
Is there any chemical type thing in our body that has to do with temperature..we must regulate somehow? My regulation of body temperature doesn't appear to function that well.
(decided I'm part ectotherm :))(I'm 33.5 and 34.5 today underarm, unless I get up above 36 my right underarm is usually 1 degree colder than left uderarm..strange no?)
But I've never thought about VitA.
Hmm I've no idea know what function VitA plays in our body come to think of it..Thanks, Jan

>well there goes that logic. Should have read all your posts first :)
I've always found too that I need the oil based A&D together.(if at all..usually only in winter)
I'd just assumed it worked well as the form of VitA and VitD maybe closer to my bodies requirements. Never really thought about needing both..just they come together in nature in this form..and also generally if they come together in nature, then that's usually how we are designed to need them.... natural selection and all that stuff)..even if we haven't worked out the why as yet.
BTW I thought the choice we have commercially was usually cod liver oil or halibut liver oil... both fish liver oils..cod or halibut. I have for the past 10 years used halibut liver oil I thought? Do you find one better than the other?Grin, remember before I confused the two re carotene?..its like I said, I've always thought about them together..except on the parathyroid /calc/VitD/phosphate path.
At a stretch I guess extra VitD could caus extra calcium (given sufficient amounts of other things..oestogen being one of probably lots)
and calc could lower available thyroid hormones in those on T4 replacement..which may feedback to pit/hypo and raise TSH..if that pathway is working optimally!
Is this logic correct? BTW I always welcome/enjoy constructive critism.

All the co-factors might be necessary combined with NAC - Thiodox is an excellent supplement. Glutamine is useful in raising glutathione as it can also buffer cellular acidity, as well as supply gluatamate for glutathione. My own practitioner gave me something by jarrow called 'homocysteine pf' yesterday which helped me massively. I talked to her about my concerns about my poor methylation and how it's required for creatine prouction and acidity buffering - so we checked it out and found I was really high in folate (like Jan) but couldn't use it - homocysteine PF got my folate working (checked with kinesiology). As glutamine and methylation improve my fog too, I think part of the 'fogginess' may be because I'm too acid.

Ray,
Since I've been working the past couple of days and will be again tomorrow, I haven't had much time to answer these or read the citations. I was going to wait until this weekend to respond but I have the feeling that with all of this activity here, the train will have taken off if I wait until then...In answer to your post, what is "captomer" - something to be taken in place of NAC, with it or just separately to prevent mercury from entering the brain? Also, what is Thiodox? Do you believe that I should take the NAC and if so, what dosage? Do you think that there is any concern about taking l-glutamine? (in respect to it's producing too much glutamate which can serve as an excitotoxin). What is a reasonable dosage then for l-glutamine? (Had you read any of the posts below on this topic?) I hadn't realized that it played an important role in the immune system as your abstract indicated but by taking it are you helping your immune system while doing damage to your brain? Also, if creatine allows for methylation, then what is a good dosage to take of that? Do you recommend that for everyone or only for those with a methylation problem. If one has a methylation problem, then how does one determine that?
Actually, I have a book at home here by Dr. David Perlmutter. It’s called "The Better Brain Book." He has a dosing schedule of various supplements to take for various levels of need. It’s written for the masses so it’s easy for people like me to read but he has also published some more in depth articles on the topic. He’s a neurologist with a holistic bent – not a very common combination. Anyway, I guess I should follow his dosing schedules when I can afford to. He doesn’t have creatine or l-glutamine on there at all however, so I’d still be especially interested in how much of that you recommend taking.
Thanks,
KaraP.S. Simus isn’t the only one who can ask a lot of questions!

>
> How do you do on chocolate or salami?!!
Ray,You're saying that my favorite "food" of all time could be the very thing that saves me????
It reminds me of that Woody Allen movie where he wakes up a long time into the future and he is told that sugar (ice cream sundaes, cakes etc.) are the true health foods.
Anyway, I LOVE CHOCOLATE! I guess I could say that I do well on it. I crave it unbelievably. I've guessed that I was low in PEA because of that and also because I read that it is implicated in "rejection sensitivity." I am extremely sensitive to rejection. Because of this I thought that I would do well on the combination of selegilne and DLPA or l-phenylaline. However, the selegiline made me sleepy and then about 8 hours later made me stimulated (definitely some malfuncion there). I can't remember if I tried combining it with DLPA or l-phenylalanine yet. I do remember that I took some chocolate with it and I got really shakey from too much PEA. At any rate, because of the strange reaction to the selegiline, I gave up on it. Now I'm thinking that if the PEA might decrease the amount of D1-like dopamine (DA) receptors, then it might be worth trying again. I wonder if it's only the D1 receptors that are involved. Those are the Parkinson's related receptors, no?

Ray,
You didn't attach an abstract above but that line of thinking is what brought me to the super sensitive DA receptors researching to begin with. I read a short article by Dr. Jay Goldstein. He theorized that those who reacted paradoxically to stimulants, did so because of hypersensitive DA autoreceptors. He specialized in treatment for Chronic Fatigue Syndrome and his theory included the position that the DA autoreceptors problem could be caused by CFS. Since I have CFS that was caused by a virus (definite viral onset), this all made sense to me.K

Hi Ray,
I looked up homocysteine PF by Jarrow yesterday(and had a glance at a few other supps you take too)
http://www.iherb.com/tmgb12b6tab.htmlVitamin B6 (Pyridoxine HCI) 15 mg 750%
Methyl B12 (Methylcobalamin)250 mcg 4167%
Folic Acid 400 mcg 100%
Trimethylglycine (TMG) 500 mg (Anhydrous Betaine)so it looks to me like it just has normal Folic acid in it..not the special form you mentioned(FOLINIC ACID (5-formyl tetrahydrofolate))
..but it does have Betaine in the TMG form. Lar takes that on I think..the TMG.
Do you think it's the TMG?TMG is another I have to order from O'seas.
Sigh, and I'm beginning to run out of the stuff I bought in England..should have bought a lot and posted it back..as well as imported some from the US into England.Twas enough getting some citrate forms of Mg, Ca, zinc, and a few others like a higher dose Ferrous fumurate etc..as well as progesterone and oestradiol<g>.
I was taking 500mcg Folic acid together with a multiB for a while..didn't notice any diff..in fact I feel a lot less panicy since dropping the CoQ10 and folic acid (labeled folate..folic acid 500mcg)and more able to cope with some tasks...not big tasks..little things like making a phone call.
On another forum I remember now it was found we need NADPH and oxygen to break down glutiathone...bet I'm short there...everything abouyt me keeps coming up with a shortage of NADPH and oxygen, sigh.
I'll find the link
http://forums.about.com/ab-thyroid/messages?msg=52183.49oh yes you migh be interested in this too
http://forums.about.com/ab-thyroid/messages?msg=52183.47 ..just to change the topic around
I'm a lot better off with more carbs..and I've found more since..just can't remember what or where now, sigh
Oh yes on not breaking down chloresterol..another thing I've got..something about the low carb diet preventing chloresterol catabolizing to CoQ10 I think from memory..won't change onto that one!
Just to be more complicated..I also have difficulty with all forms of B12..methylcobalamin, hydroxycobalamin injections..my hands turn either bright red or a purply shade and tingly..same with my feet.
My Mum's hands go a bit red..not as severe as mine. Happens all the time..not as severe if I keep up with the injections but still happens..that's why when I got my B12 levels up I stopped! I even had multiB's made up w/o the B12 for a while just to see if I felt better.
I sem to be fine witha little cyanocobalamin that is in the multiB's over in Oz at present..well I don't notice much diff anyway.
This may possiby be a G6PD partial deficiency or perhaps that combined with methaemoglobulin problesm that I seeme to have after a dental anesthetic last year.
It's on the forum here last Sept.somewhere. If you have anything like that I could look up the posts..doubt it though. on the other had, if you know what it is, I'd love to know for sure!Found out I don't vasoconstrict...last hole I just skipped the anesthetic..drill felt exactly the same.
Today I found out I'm lowish on ADH (Vasopressin)..hence the too little vasoconstriction, sigh
yeah I learnt if one has a needle always get the adrenalaine..then take cortisol after I guess to lower it maybe...
Gee it makes it err challenging.
That's why I'm trying to go to uni to learn enough to figure it out..takes a long time though..especially when I can't just order the tests I need, sigh. Just wish I had a higher fraction of my old brain left to learn and think with.And all these things seem to cause a tad of anxiety, depression etc, LOL

Also, would you mind sharing what your diagnosis was?No, I don't take any meds - really happy with how my supplements work out for me. Think my doctor dignosed me as a pain in the ass! I've tended to label myself as chronic fatigue, but it's been mainly the brain fog in the last few years. The immune system gene errors (great smokies test) are a big factor, I beleive.

Vitamin A apart from being a fat soluble antioxidant, and the first line of defence against infection, also works at DNA level to control genes. Like vitamin D it can speed up or slow down the rate at which neurotansmitters, enzymes and receptors are produced....only realised this today! Steroid hormones do the same - neurotransmitters control the production of steroid hormones, then homones control production of neurotransmitter genes - it's quite neat!Ray

I'm finding there's not enough vitamin D in fish oil for me. I use halibut oil (not sure if it's liver or not) for vitamin A, but don't know if it's any better than cod? It's the mercury and PCB content that really concerns me more than the fish.

I'm not sure of the way it would do that? Saw in interesting idea reagrding vitamin A an article said thyroid receptors can become over sensitive during hypothyroid, so when T3 or T4 is supplemented, a person can be a little 'hyper' - vitamin A can desensitise the T3 receptor to help with this - not sure it would be good in some cases though!

> In answer to your post, what is "captomer" -
captomer is like NAC but it is claimed that it doesn't cross the blood brain barrier, so can't carry mercury into the brain - not sur if that's true or not!
>Also, what is Thiodox?
It's a glutathione formula conataining NAC, selenium, B2 vit c, ala and glutathione
Do you believe that I should take the NAC and if so, what dosage?
I only do well on NAC for a few days, then feel nauseous - can take thiodox for longer, but still ends up causing nausea eventually - think I run low on other b vits etc, and need time to replace them before I can start another course..
Do you think that there is any concern about taking l-glutamine? (in respect to it's producing too much glutamate which can serve as an excitotoxin). What is a reasonable dosage then for l-glutamine?Yes there's always a worry about glutamine, but I can't tolerate glutamate but do really well on glutamine - my gut loves it
(Had you read any of the posts below on this topic?) I hadn't realized that it played an important role in the immune system as your abstract indicated but by taking it are you helping your immune system while doing damage to your brain?
Haven't follwed the posts on glutamine - think it's individual how it works with people, know a couple of other people who do well on it, even though they're sensitive to glutamate - not sure why, will have to look at the posts!
Also, if creatine allows for methylation, then what is a good dosage to take of that? Do you recommend that for everyone or only for those with a methylation problem. If one has a methylation problem, then how does one determine that?
Creatine can reduce autoimmune problems, so I would guess that methylation would be a problem in a lot of autoimmune disease sufferers - as for dose, I'm taking 4 tablets of 'homocysteine pf' by jarrow a day - how do you do on betaine, b12 or folate? Beetroot juice is a good source of betaine by the way.

> Actually, I have a book at home here by Dr. David Perlmutter. It’s called "The Better Brain Book." He has a dosing schedule of various supplements to take for various levels of need. It’s written for the masses so it’s easy for people like me to read but he has also published some more in depth articles on the topic. He’s a neurologist with a holistic bent – not a very common combination. Anyway, I guess I should follow his dosing schedules when I can afford to. He doesn’t have creatine or l-glutamine on there at all however, so I’d still be especially interested in how much of that you recommend taking.
>I've got a david perlmutter book called "brainrecovery.com" - think he's excellent. He doesn't have creatine but he does spend a lot of time talking about homocycsteine, which is high when creatine is low - and homocysteine is an excitotoxin too.
Yeah, you're right, he doesn't mention glutamine - but I can take a gram a day and feel really good, but I do hear your concerns...

Hi Jan, have got to get to bed, so can't answer all your questions today....but yes homocysteine pf only contains folate, but it works wonderfully for me, must be just a good balance for my system.
I was wrong about folinic acid it's tetrahydrofolate, and not fully activated to it's methyl state. But folate to tetrahydrofolate still needs 4 NADPH molecules, and to make the methyl tetrahydrofolate in needs methyl B12, B2 and another NADPH. when folate is used, it then needs B6, manganese in one step, then B2, NADPH and methyl b12 again - if any one of these is in short supply, it all fails! If your low NADPH, that might be why methyl B12 causes a problem, it might accelerate the decline of NADPH?Ray

> Oestradiol exerts an important modulatory influence on the release of prolactin which is accomplished partly through disruption of the inhibitory influence of dopamine. We have focused on the status of the anterior pituitary D2 dopamine receptor in female rats treated chronically with oestradiol or progesterone. A direct membrane effect of these steroids on the dopamine system was also investigated in vitro. Both steroids affected the status of the D2 receptor, oestradiol decreasing the number of sites in vitro and progesterone increasing it both in vitro and in vivo. The in vitro studies demonstrated that these steroids exert a direct membrane effect on the D2 receptor. These results correlated with an in vitro short-term physiological effect of oestradiol and progesterone on the dopaminergic inhibition of prolactin release, oestradiol decreasing it while progesterone had the opposite effect. Binding studies with [3H] oestradiol on pituitary membranes revealed a site for oestradiol of high affinity and low capacity, indicating that oestradiol's membrane effects could be mediated by a specific receptor. In vivo treatment with oestradiol also induces proliferation of prolactin-secreting cells (lactotrophs). We focused on the effect of oestradiol on protein kinase C activity, which is involved in both secretion and proliferation. In female rats treated with oestradiol total protein kinase C activity was increased by 74% (particulate 90%, soluble 71%) in comparison with controls. This effect was reversed by concomitant treatment with a dopamine agonist. Thus in the pituitary oestradiol and progesterone affect the characteristics of membrane components that are implicated in the physiological control of the cell. Whether these effects are post-transcriptional only or are also mediated through direct membrane mechanisms needs further investigation.
