Xenobiotic Effects on COMT

A xenobiotic is a foreign chemical substance found within an organism that is not normally, naturally produced by or expected to be present within that organism. It can also cover substances which are present in much higher concentrations than are usual.41_SchemaRTS_Eng

  • In humans, 2-Oh and 4-Ohestradiol (catechol estrogens) are rapidly O-methylated to form monomethyl ethers catalyzed by COMT and S-adenosyl-L-methionine.

  • Xenobiotics may strongly inhibit COMT-mediated
    O-methylation of catechol estrogens by xenobiotics and may facilitate the development of estrogen-induced tumors.

  • Xenobiotics may therefore deplete intermediates in the Folate cycle.  Environmental burden of Xenobiotics may create a higher need for methylation support.

Catechol-O-methyl_transferase_baucom-instituteAbstract: COMT genotype, micronutrients in the folate metabolic pathway and breast cancer risk - Goodman JE, Lavigne JA, Wu K, Helzlsouer KJ, Strickland PT, Selhub J, Yager JD; Department of Environmental Health Sciences, Johns Hopkins University, Bloomberg School of Public Health, Baltimore, MD 21205, USA.

  • Catechol-O-methyltransferase (COMT) catalyzes the O-methylation of catechol estrogens (CEs), using S-adenosylmethionine (SAM) as a methyl donor.

  • Several studies have indicated that the val108met COMT polymorphism, which results in a 3-4-fold decrease in activity, is associated with increased breast cancer risk.

  • Folate, whose intake levels have also been associated with breast cancer risk, and other micronutrients in the folate metabolic pathway influence levels of SAM and S-adenosylhomocysteine (SAH), a COMT inhibitor generated by the demethylation of SAM.

  • Because these micronutrients have been shown to alter SAM and SAH levels, we hypothesized that they could also affect COMT-catalyzed CE methylation.

  • Although measurements of SAM and SAH were not initially collected, a secondary analysis of data from two nested case-control studies was performed to examine whether serum levels of folate, vitamin B12 (B12), pyridoxal 5′-phosphate (PLP), cysteine and homocysteine, in conjunction with COMT genotype, were associated with breast cancer risk. COMT(HH) (high activity COMT homozygote) breast cancer cases had statistically significantly lower levels of homocysteine (P = 0.05) and cysteine (P = 0.04) and higher levels of PLP (P = 0.02) than COMT(HH) controls. In contrast, COMT(LL) (low activity COMT homozygote) cases had higher levels of homocysteine than COMT(LL) controls (P = 0.05).

  • No associations were seen between B12, COMT genotype, and breast cancer risk. An increasing number of COMT(L) alleles was significantly associated with increased breast cancer risk in women with below median levels of folate (P(trend) = 0.05) or above median levels of homocysteine (P(trend) = 0.02). These findings are consistent with a role for certain folate pathway micronutrients in mediating the association between COMT genotype and breast cancer risk.

These findings are consistent with a role for certain folate pathway micronutrients in mediating the association between COMT genotype and breast cancer risk.

The X Factor

the-x-factor-metabolic-syndrome-baucominstitute

We’re always looking for the next big thing but the next big thing is already here – Metabolic Syndrome X – the biggest problem in America! The USA has the highest percentage of obese in the world, 34% female and 27.7% male, 35% of whom are Mexicans and 40% African American males.

What is Metabolic Syndrome X? In our blog last week, we shared that this syndrome is a result of having three or more metabolic risk factors: insulin resistance, elevated blood pressure, abdominal obesity, high lipids – TG, LDL, etc.

“94% of the rats who were allowed to choose between sugar and cocaine, chose sugar. Even rats who were addicted to cocaine switched their preference to sugar!”

Here are the symptoms:

  • Borderline high or normal blood glucose
  • High triglycerides (above 2.3 mmol/l)
  • Low HDL (good cholesterol)
  • High blood pressure
  • Hypoglycemia
  • Excess weight resistant to dieting
  • Skin tags
  • Osteoarthritis

According to researchers at Yale University School of Medicine, insulin resistance in skeletal muscle leads to changes in energy storage and insulin-resistant individuals rerouted carbohydrates to liver fat production. This leads to elevated triglycerides in the blood by as much as 60% while lowering HDL (good) cholesterol by 20%. In a study done by Yale, participants who were young and lean, with no excess abdominal fat became insulin resistant. The good news is, they found that insulin resistance in skeletal muscle can be treated with one simple method – exercise!

Let’s talk about sugar for a moment, because that it ultimately the biggest culprit in the cause of The X Factor.

The average American eats 142 pounds of sugar a year, or about 2.5 pounds each week, a 23% increase over the last 25 years! And most of it is coming from, one guess . . . soft drinks – which includes artificially sweetened drinks as well! In the US, ¼ or 22% of the daily calories are from drinks, according to a report called “What America Drinks.”

According to Drs. Fischer, Hommel, Fiedler, and Bibergeil, in a study done on “reflex mechanism on insulin secretion,”  we are seeing that soft drinks are linked to Metabolic Syndrome:

  • Men and women who drank more than one soda daily had a 48% adjusted higher prevalence
  • insulin level rises in the first minute after the start of a carbohydrate-rich meal, vs glucose level rising in the third minute of a balanced diet
  • An increase in triglyceride levels and LDL
  • Consumption rose 135% of high fructose corn syrup between 1977 and 2001
  • Americans eat an average of 132 calories of high fructose corn syrup a day

In a lab experiment with rats by the University of Bordeaux called “Intense Sweetness Surpasses Cocaine Reward,” 94% of the rats who were allowed to choose between sugar and cocaine, chose sugar. Even rats who were addicted to cocaine switched their preference to sugar!

Obviously, we have to get over our addiction to this satiable substance! In the meantime, many changes have to take place to get this X Factor under control.

Doctors, in weight-loss fields, GP’s, restorative, and otherwise, are all finding that to get this syndrome under control several factors have to take place:

  • Balance glucose/insulin levels
  • Increase metabolism
  • Increase fat burning
  • Create appetite suppression

A study done by Sweden’s Karolinska Institute European Association for the Study of Diabetes found that a natural substance can greatly help in this fight:  Green Tea Catechins or EGCG (epigallocatechin gallate). After 5 and 10 weeks of treatment with EGCG, and GlaxoSmithKline’s diabetes drug Avandia, the blood sugar and insulin levels of mice were tested. The researchers found that the mice did just as well on the green tea extract as they did on the drug. The extract has been found to have these benefits:

  • Reduces fat absorption
  • Reduces LDL cholesterol/TG levels
  • Reduces glucose/insulin levels
  • Increases beta oxidation
  • Helps decrease appetite

Which ultimately:

  1. Reduce body weight gain
  2. Reduce body fat accumulation
  3. Stimulate oxidation in the liver

All in all, here are the recommendations by Alexander McLellan, ND, Neuropathic Physician in Halifax, Nova Scotia, and professor at the Canadian School of natural Nutrition and Chief Medical Officer for three clinical research trials in Diabetic Neuropathy in Canada and the US, in treating obesity and Metabolic Syndrome: Check thyroid function, Restrict carbs, Check for food allergies, Keep hydrated, Get stress levels down, Get to a support group and stay educated, Detox, detox, detox! The bottom line? It’s the samo, samo:

  • Eat right
  • Exercise more
  • Don’t rely on a “magic pill”

Disease Prevention Over Disease Management

american-heart-monthSomething tragic has happened in America’s clinical health agenda. Doctors have trained patients to rely on medicine for the answers rather than on learning ways to help themselves prevent their reliance on medicine or on medical help. The medical community has it all backwards.

You go to the doctor and you get medicine to deal with your issue. You go to the pharmacy to get the medicine the doctor prescribed to deal with your issue. In all that time, there is only an emphasis on how to treat the symptoms of the real problem not really prevent the problem from happening in the first place.

Longevity management medicine places emphasis on disease prevention versus disease treatment. Its medical protocols involve extensive initial laboratory baseline testing, hormone balancing, laboratory test monitoring, patient education, proper diet, nutritional supplementation and appropriate exercise.

At Baucom Institute, for instance, we go to great lengths to find where the patient is in terms of their health when they come to see us and then through extensive testing we determine the proper course of treatment and educating the patient how to change their own lifestyle so that they can help themselves change their own course toward health.

The Baucom Institute is interested in a quality of care with outcome measures which include: improved laboratory test profiles, enhanced strength, increased endurance, and a greater feeling of wellness as the patient works along with Dr. Baucom to achieve personalized life enhancing goals.

Introducing: “The Baucom Institute”–To Life and Longevity!

Dr B DeskWhen you think of “age management” maybe you think of nursing homes or elder care. If you aren’t aware, the statistics show that people are living longer because of advancements in medicine. However, are they living well in their older years?

That’s what The Baucom Institute is all about—life enhancement and age management, “ . . . an emerging field of medicine devoted to maintaining or enhancing the quality of life as we age. It does not prevent aging or necessarily lengthen our life, but rather qualifies and alters the way we age to enhance the quality of life as we age.” –Karan Baucom, MD, FACOG, FAAAAM

As we age, we become susceptible to disease and the breakdown of our body systems. Dr. Baucom has created a program whereby assessment of the patient is made to determine areas of concern and to determine the best course for preventing any further issues. The protocols for assessment include:

  • Extensive initial laboratory baseline testing
  • Hormone balancing
  • Laboratory test monitoring
  • Patient education
  • Proper diet
  • Nutritional supplementation
  • Appropriate exercise

When all the testing has been assessed, Dr. Baucom’s plan of care will include:

  • Improved laboratory test profiles
  • Enhanced strength
  • Increased endurance
  • A great feeling of wellness

Dr. Baucom always says, “Age is only a number, not a way of life.” There are answers in regenerative medicine— comprehensive assessment, tailored care, hormone balance for men and women, nutrition, and exercise. The answers are available for quality of life and youthful vitality.
