Please note : Should you decide to follow the regimen, you do it at your own risk.


Dear All,

After many years of Brain Fog, Psychological Problems, Orthostatic Intolerance, Thyroid Problems, Testosterone Problems, i am totally recovered.

Since i was not getting any help from Doctors and my Health was deteriorating, i decided to take things in my own hands. I started logging whatever was happening to me, what i was eating, what supplements i used, how was the weather, etc. Then i used special techniques (aka Data Science) to identify the common characteristics of Good Days vs Bad Days, analyze thousands of Pubmed Research Articles and find the root cause of my problems.

Quite possibly, a key Element behind our problems has to do with Endoplasmic Reticulum (ER) stress, Misfolded Proteins and the the subsequent Unfolded Protein Response (UPR). Anything that impairs proper folding of Proteins within the ER ultimately leads to UPR and the Majority of our problems. At the end of the post you can find relevant References regarding why Methylation problems, Tetrahydrobiopterin Production Impairement, Celiac Disease, N-Linked Glycosylation impairment (among others), all create Stress within the ER and then signal a UPR.



Some Causes for Misfolded Proteins / ER Stress (i will be updating the list as necessary) :

a) Methylation problems
b) Choline Deficiency
c) Celiac Disease (Gluten Intolerance)
d) Impaired BH4 (Tetrahydrobiopterin) Production & Phenylketonuria
e) Impaired N-Linked Glycosylation (e.g from Statins , HmG-CoA Inhibitors)
f) Pathogens (Credit to @@adreno - see his post below)
g) Impaired Calcium Homeostasis
h) Methamphetamine Use (Possibly)
i) Sedentary Lifestyle
j) Insulin Resistance
k) Obesity

l) High Cortisol from Stress and Weather Changes (Credit to@@Ema - see her post about Weather Changes and how it could be affecting us below)

m) Environmental Toxins (Credit to @@JPV - see his post below )
Now imagine the following scenario : There exists a bucket which is filled by any of the above causes with water. If you do not act either by avoiding filling the bucket with water and/or by making sure that some of the water is thrown at regular intervals then the bucket will eventually overfill. And this means trouble.

In other words, if you have ANY of the above stressors, your "Bucket" is being filled and you must stop this. My theory is that this is the problem behind the Methylation Support Regimen that was proposed by Fredd / Rich Van Konynenburg. They dealt with one aspect of ER Stress only (namely Methylation problems and Increased Homocysteine which causes ER Stress). But if you have more than one Stressor going around then you will not have a full recovery.

The key elements of the proposed regimen are using any agent/supplement/actions to prevent Protein Misfolding and Endoplasmic Reticulum Stress and at the same time avoid actions that induce Protein Misfolding.

To help proper Protein Folding and ameliorate ER Stress the following Actions/Supplements are recommended :

-Methylation Protocol (If you have Methylation problems you must follow it according to your Gene mutations)

-Choline supplementation : Choline deficiency is very common and should be addressed because it leads to NAFLD (Non-alcoholic liver disease) and ER Stress. You must be aware of possible SNPs on the following genes :


rs3733890(Risk A)
rs2461823 (Risk C) NAFLD Disease
Rs7643645 (Risk G) NAFLD Disease
rs7946 (Risk T) (PEMT)
rs4244593 (Risk G) (PEMT)
rs2236225 (Risk A) (MTHFD1)
rs9001 (Risk G) (CHDH)


If you have several SNPs in the genes listed above, then you should supplement with Choline up to 700 mg per day and see how you feel.

-TUDCA : ameliorates Misfolded Proteins/ER Stress

-Taurine : Ameliorates ER Stress

-Vitamin C : Boosts BH4 functionality in case you have impaired production. I have reduced Tetrahydrobiopterin production therefore i use Vitamin C to increase it. Phenylketonuria creates Endoplasmic Reticulum Stress and Unfolded Protein Response

Key Genes :


GCH1
rs10483639( Risk C)
rs3783641(Risk A)
rs8007267(Risk T)
rs12147422 -(Risk C)
rs3783637 - (Risk T)
rs3783641 - (Risk A)
rs41298442 - (Risk T)
rs4411417 - (Risk C)
rs752688 - (Risk T)
rs841 - (Risk A)
rs998259 - (Risk T)
rs7147286 - (Risk A)

PAH Gene

rs10860936 (Risk C)
rs1722387 (Risk C)
rs1522305 (Risk C)
rs1522296 (Risk A)
rs772897 (Risk C)
rs1522307 (Risk G)
rs11111419 (Risk T)



-Selenium : Deficiency/Over-supplementation increases ER Stress. Induces HSP70, Prevents Protein Misfolding. Note that P5P (=Active form of Vitamin B6, Part of Methylation support regimen) is essential for proper Selenium metabolism.

-Curcumin: Ameliorates ER Stress by boosting HSP70 (Heat Shock Protein). NOTE : High Curcumin intake (=In Supplement form) acts as a DHT Inhibitor.

-Vitamin D3 : Ameliorates ER Stress, Induces HSP70 but it can be problematic to some people because it increases Calcium Absorption which could cause Symptoms if your Calcium Homeostasis is impaired.

-Resveratrol : Induces HSP70. Note that many Resveratrol supplements contain Vitis Vinifera extract which is a potent HmG-CoA Inhibitor (Statin drugs are also HmG-CoA Inhibitors).

-N-Acetylglucosamine (NAG) : Could play a role in controlling ER Stress. DO NOT take NAG and sweets or anything else that increases Glucose levels at the same time.


Note : Foods high in Cholesterol and Glucose increase HmG-CoA activity which is beneficial for us but it is not suggested that you increase HmG-CoA by having Foods high in Cholesterol and Sugar!

-Caloric Restriction (But don't go overboard) : Induces HSP70. Note however that severe drop of Insulin Level (Hypoglycemia) stops HmG-CoA production which for us could be a problem. Probably a good practice is to not eat anything for a day apart from drinking water. Check with your doctor that this is ok for you to do.

-Calcium : Ensure that you have normal calcium levels. Calcium is VERY critical for proper handling of Endoplasmic Reticulum Stress but it can be a double-edged sword if Calcium homeostasis is not functioning properly. In this case, supplementing with Calcium will worsen your symptoms. It is recommended that you first supplement with Magnesium (Calcium Antagonist) and see how you feel.




STAY AWAY From :

P450 Inhibitors : Grapefruit, BioPerine, Quercetin, Capers (High in Quercetin). Caution : A lot of Supplements use Bioperine for increased absorption. Check Labels!

HSP70 Inhibitors : Quercetin, Capers (High in Quercetin),Myricetin, Luteolin.

Gluten sources (If you are Gluten intolerant) : Induces Oxidative Stress

MSG Sources / Phenylalanine Sources : Parmesan, Whey Protein, Aspartame of any kind

HmG-CoA Inhibitors : Statins, D-Limonene, L-Carnitine, Orange Juice, too much Olive Oil (Oleic Acid), Olives,Vitis Vinifera extract.

N-Linked Glycosylation Inhibitors/Disruptors : Statins, Thapsigargin, Tunicamycin, Brefeldin A, DHT Inhibitors (e.g Finasteride/Propecia, Saw Palmetto, Green Tea)

Oxidative Stress avoidance : Intense workouts, Extreme Weather changes (not much you can do about this), Psychological Stress, Testosterone Induction (Testosterone boosting creates Oxidative Stress)

Other foods /supplements :Ashwagandha, ENADA/NADH, Ginkgo Biloba, Royal Jelly, Oats (not sure why i didn't feel good with those)



My Regimen :

-Methylation Support : Dibencozide (Adenosylcobalamin) , P5P (apart from Methylation, important also for proper Selenium Metabolism), Metafolin
-ER Stress support : TUDCA, Curcumin (i either use turmeric powder sprinkled in salads or use Mustard). Some olive oil is used for better absorption.
-Vitamin C
-Selenium
-NAG
-Complete Elimination of Alcohol because of TUDCA Supplementation.
-Avoidance of P450 Inhibitors, DHT Inhibitors, HSP70 Inhibitors, etc

My current regimen :


08:00
Metafolin 2000 mcg
Dibencozide 1/4 tablet
Mucuna Dopa 100 mg
N-Acetylglucosamine 700 mg
Taurine 500 mg

10:00
Choline 350 mg


12:00
P5P 50 mg
Selenium 100 mcg
TUDCA 250 mg


16:00
5-HTP 50 mg
Taurine 500 mg
N-Acetylglucosamine 700 mg


20:00
Vitamin C 500 mg
5-HTP 50 mg
Choline 350 mg

23:00
NAG 700 mg


24:00
TUDCA 250 mg


ALCOHOL IS NOT ALLOWED WHILE YOU USE TUDCA.


I would also appreciate your feedback should you decide to do this regimen. Also, Please try to see if Weather Changes are affecting you and let me know.You will have side effects BEFORE the weather front hits you. For my symptoms there was a clear pattern of Side Effects being associated with Abrupt Weather Changes such as Temperature Drop, Barometric Pressure Drop and Wind picking up with Temperature Dropping abruptly being the worst.

It appears that weather induces Protein Misfolding and as a consequence Stress within the Endoplasmic Reticulum which our bodies cannot handle.



This is the complete list of Side Effects i experienced for more than 7 years :

Depression & Suicidal Thoughts
Poor Memory
Early Morning Insomnia
"Brain Fog" - Inability to think clearly
Impaired Speech
Low Energy
Social Anxiety
Dysphagia
Constipation
Urticaria
Orthostatic Intolerance
Tinnitus
Sudden Hearing Loss
Hypothyroidism
Secondary Hypogonadism
Numbness in Extremities
Bradycardia
Cardiac Arrhythmias
Restless Leg Syndrome
High Cholesterol
Pain on Neck, Waist, Elbows areas
Impotence
Anorgasmia

A user called "trynottoworry" first discussed the importance of Unfolded Protein Response in trying to identify what happens with the Post-Finasteride Syndrome. My problems originated right after quiting Finasteride (Propecia) for Hair loss. I believe that Chronic Fatigue Syndrome, Post-Finasteride Syndrome and cases of people with Permanent Side effects from Drug 'Accutane' share all the same mechanism.

I will be editing this first post with new information/things to avoid. Please visit http://solvepfs.com and look at the Thread called SRD5A3/Mevalonate if you want to know more.

Good Luck

More about tudca :

Tauroursodeoxycholic acid, more commonly referred to as TUDCA, is a bile salt that is found natrually occurring in the body. When regular bile salts reach the intestines, they can be metabolized by bacteria into UDCA and then later bound to a Taurine molecule to become TUDCA.

TUDCA is a water-soluble bile salt, which is in contrast to regular bile salts possessing both water soluble and fat soluble ends and conferring a detergent effect. This is good for the bile salt's biological purpose (emulsifying fats in the intestines to help with absorption) but when bile acids back up in the liver, a clinical state called cholestasis which occurs when the liver is unhealthy, these bile salts can be damaging to cells by destroying the membranes and signalling for cell death. TUDCA and other water soluble bile salts like UDCA compete with this toxicity and thus indirectly protect cells from death.

Additionally, it seems that TUDCA is able to reduce stress to any cell's Endoplasmic Reticulum; an organelle in cells that serves as a highway from the nucleus out into the cytoplasm, and aids in folding proteins. Through reducing ER stress, TUDCA has been implicated in a wide range of beneficial metabolic effects such as reducing insulin resistance and diabetes, and being a neurological protection agent. However, usages of TUDCA beyond the liver are preliminary whereas usage of TUDCA for helping an already harmed liver is quite reliable as TUDCA is used in clinical settings (hospitals) for treating cholestasis.

Here's more:

Ursodeoxycholic acid inhibits the intestinal uptake of cholic acid lead to increased loss of cholic acid into the colon, with the consequence of increased formation of the secondery bile acid, deoxycholic acid.

TUDCA leads to significant reduction in the biliary composition of the hydrophobic bile acid and chendeoxycholic acid (13) . It suppresses hepatic synthesis and secretion of cholesterol inhibits intestinal absorption of cholesterol, but it does not inhibit the synthesis of endogenous bile acids (14) .

In addition, it also solubilizes cholesterol in micelles and causes dispersion of cholesterol as liquid crystals in aqueous media. Overall, it makes the bile conducive to cholesterol stones dissolution. It occurs naturally in bile, where it has an important role in controlling the concentration of cholesterol in the blood .It causes a competitive blockade of bile acid reabsorption in terminal ileum, causes cholesterol desaturation in bile without raising serum cholesterol levels, which prolongs the nucleation time of gallbladder bile by shifting cholesterol from vesicles to micelles (15) .

It is prescribed as an alternative to surgery in the treatment of gallstones. It acts by reducing levels of cholesterol in the bile.
So that seems to indicate that it would work synergistically with something like cholestyramine...helping to increase the amount of bile produced and shuttled through the gallbladder so cholestyramine could have even more opportunity to bind up the biotoxins as they come through.

But I'm not at all sure about this.

Especially in light of this:

There are a few drugs that have important interactions with ursodeoxycholic acid; these include clofibrate, cholestyramine, and other cholesterol-binding or bile acid–binding sequestrants. Estrogens may increase biliary cholesterol levels, whereas charcoal and some antacids may bind bile acids.
Would have been handy if they'd bothered to mention what those important interactions actually are...there are no such interactions listed on the interaction checker at drugs.com.

This article suggests that it impairs absorption:

The absorption of ursodeoxycholic acid was impaired by colestyramine, colestimide, colestipol, aluminium hydroxide and smectite.
The anion exchange resins, colestyramine,92–94 colestimide95 and colestipol,94 bind UDCA in the gut and thereby interfere with the absorption of UDCA. Aluminium hydroxide and smectite are notable for their propensity to form complexes with UDCA which are not absorbed.94 Therefore, it is recommended that these drugs are administered with an adequate interval to UDCA.96
Who knows what that interval actually is? And does it also apply to TUDCA?

Also that UDCA is an inducer of the CYP4503A4 system which also metabolizes many other drugs and steroid hormones like cortisol:

In particular, UDCA has been shown to be an inducer of the CYP3A subfamily.
So far, however, the effect of UDCA on the substrates of CYP3A has not been studied in detail and the clinical relevance of CYP3A induction by UDCA remains unclear.

Tudca is also quite expensive. Perhaps taurine could work as a cheaper surrogate (although not quite as effective)?

@mariovitali, what is HmG-CoA (some intermediate in ketosis?), and why is that important?

HmG-CoA is needed for proper Mevalonate Pathway function. Most Statins function by inhibiting HmG-CoA. As a result you lower Cholesterol but Mevalonate Pathway is a very important one since production of key neurosteroids and steroids is affected.

Regarding Taurine you are right, it can also work in the same way although most studies that i've found discuss about TUDCA and its ability to limit Protein Misfolding and UPR.

Unfortunately i do not know if we have a way to measure which of these compounds (TUDCA, Selenium, Resveratrol, Taurine, Vitamin D3, BH4) works better.

This is very interesting! I just recently learned that a lack of sleeps makes a person feel "worse" (even healthy people) because it results in folded proteins.. So makes sense that this could be a big component of the illness. I had been pondering this, and up came your post!

I have this symptom too and I hate it. For me though, it's caused by low cortisol since weather fronts cause an increase in cortisol. I'm on replacement for adrenal insufficiency and I often have to stress dose for storms. When I'm properly covered with steroid, I don't notice the fronts.

I will never forget what happened the night i had my initial crash. I was taking Finasteride and decided to quit it. Finasteride possibly generates problem on N-Glycosylation through downregulation of SRD5A3 (this also impairs proper Protein Folding). I was on diet at that time and decided to eat lots of Protein through consuming Egg Whites.

I broke into Hives and had Tinnitus, Joint Pains, Difficulty swallowing,Impotence and Red Spots in my palms. The Doctors couldn't understand what was happening but now i know : Egg whites contain a lot of Phenylalanine. By taking Finasteride and at the same time being BH4 deficient i triggered a severe Unfolded Protein Response.

It took me months to get well and i was taking antihistamines for Hives for more than a year. I thought this was over but then, as years passed by, problems started again. For me, a Tinnitus incident would signal an Unfolded Protein Response. Then as time passed by, more problems started appearing like Brain Fog, Inability to Sleep, Thyroid problems. I was a real mess.

The first String in the list has the format xyz.csv and then you have a number as percentage.

The xyz is actually a research subject in PubMed. So for example, the first file is upr.csv and it contains 5153 entries of PubMed articles regarding Unfolded Protein response.

Next we have er_stress.csv which is a file that contains 11088 entries of PubMed articles regarding Endoplasmic Reticulum Stress.

The percentage you are seeing next to the file, contains the proportion (in %) that the phrase "misfolded proteins" was found to each file.

It appears that the subject that contains the largest percentage of mentions on Misfolded Proteins is HSP70, then Calcium Homeostasis.


Now, let's find out about HSP70 itself :

It appears that HSP70 and Curcumin are discussed more frequently together within the chosen Subjects in PubMed. Of course we do not know the context of these mentions but after some reading i've found that Curcumin induces HSP70 and the same applies for Resveratrol.

Discovery[edit]
Members of the Hsp70 family are strongly upregulated by heat stress and toxic chemicals, particularly heavy metals such as arsenic, cadmium, copper, mercury, etc. Hsp70 was originally discovered by FM Ritossa in the 1960s when a lab worker accidentally boosted the incubation temperature of Drosophila (fruit flies). When examining the chromosomes, Ritossa found a "puffing pattern" that indicated the elevated gene transcription of an unknown protein.[4][5] This was later described as the "Heat Shock Response" and the proteins were termed the "Heat Shock Proteins" (Hsps).

Structure[edit]

Hsp70 proteins can act to protect cells from thermal or oxidative stress. These stresses normally act to damage proteins, causing partial unfolding and possible aggregation. By temporarily binding to hydrophobic residues exposed by stress, Hsp70 prevents these partially denatured proteins from aggregating, and allows them to refold. Low ATP is characteristic of heat shock and sustained binding is seen as aggregation suppression, while recovery from heat shock involves substrate binding and nucleotide cycling,

Upregulation in stress[edit]
Production of high levels of heat shock proteins can also be triggered by exposure to different kinds of environmental stress conditions, such as infection, inflammation, exercise, exposure of the cell to toxins (ethanol, arsenic, trace metals, and ultraviolet light, among many others),starvation, hypoxia (oxygen deprivation), nitrogen deficiency (in plants), or water deprivation. As a consequence, the heat shock proteins are also referred to as stress proteins and theirupregulation is sometimes described more generally as part of the stress response.[12]

The mechanism by which heat-shock (or other environmental stressors) activates the heat shock factor has been determined in bacteria. During heat stress outer membrane proteins (OMPs) do not fold and cannot insert correctly into the outer membrane. They accumulate in the periplasmic space. These OMP's are detected by DegS, an inner membrane protease, that passes the signal through the membrane to the sigmaE transcription factor.[13] However, some studies suggest that an increase in damaged or abnormal proteins brings HSPs into action.

I can say that curcumin helps a little, but not much. Resveratrol helps, but the inhibition of angiotensin is bad news for my OI. Creatine was just horrible. Taurine seems to help, but again can worsen OI. D3 doesn't seem to do anything good either.

In all, there's nothing on that list of supplements that has helped me significantly.

So you have Orthostatic Intolerance? Have you checked your Nitric Oxide levels?

Although these compounds are frequently discussed together, these associations tell us nothing about what induces HSP70 more (ie Curcumin or Resveratrol or....)

Did you use Curcumin in Supplement form (Meriva) or as a powder sprinked in Food?

So you have Orthostatic Intolerance? Have you checked your Nitric Oxide levels?

Although these compounds are frequently discussed together, these associations tell us nothing about what induces HSP70 more (ie Curcumin or Resveratrol or....)

Did you use Curcumin in Supplement form (Meriva) or as a powder sprinked in Food?
Haven't checked NO. Erections are fine, I suppose that wouldn't be so if I had a problem with NO. Although there are several forms of NO, so it's all a bit complicated.

I've tried curcumin mostly in different supplement formulations.

I like your way of doing research, but there is no guarantee that the researchers on PubMed has made the correct (or optimal) associations. Lots of important stuff just hasn't been researched.

This pilot investigation demonstrated that the CFS, PGI and FM subjects had a significant overlap between their syndromes. Despite the differences in their original case designations, they had very similar responses on questionnaire, quality of life and nociceptive measures. Again, despite the differences in the diagnostic label applied to them for study entry, their cerebrospinal fluid proteomes demonstrated reproducible constituents. The CFS-related proteome was essentially the same for the two independent CFS cohorts. The proteome was remarkable for the number of proteins associated with protein misfolding and cerebrovascular amyloidosis syndromes.
These included gelsolin, amyloid β protein (APLP1), Igλ ,C3, C4, chromogranin B,α2-macroglobulin and α 1-antichymotrypsin antiproteases, the heme and iron scavengers haptoglobin, hemopexin, and orosomucoid 2, angiogenic and antiangiogenic prohormones such as autotaxin and PEDF, and the structural proteins gelsolin, BEHAB and keratin 16. Their presence in the CFS – associated proteome suggested a potential pathophysiological link. We propose the hypothesis that CFS may be a nonlethal, protein – misfolding, cerebrovascular amyloidosis –like syndrome.
