Title: COUPLED DYSBIOSIS
1COUPLED DYSBIOSIS METABOLIC DYSFUNCTIONS IN
AUTISM POSSIBLE REMEDIES
- Jon B. Pangborn, Ph.D., F.A.I.C., C.C.N.
2TODAYS ASSIGNMENT
- To explore how impaired methionine-to-taurine
metabolism and reduced methylation, together with
infection, impact autism. We will consider
possible natural and nutritional remedies.
3DISCLOSURES
- Father of formerly autistic child now adult
- Left chemical engineering 29 years ago to
investigate biochemistry and autism - Past President, Doctors Data Laboratory
- Klaire Labs Consultant 1981-1999
- Great Smokies Diagnostic Lab (Genova) 1995-2005
- Cofounder Defeat Autism Now! 1995
- Coauthor Autism Effective Biomedical Treatments
- Consultant Kirkman Labs since 2000
- Senior Scientific Consultant, ARI
4IN PERSPECTIVE
- There are many different autisms
- Primarily Genetic Mostly acquired
- Inherited faults
- toxic/infectious stressors
- Considering ASD people as a group, there are
cell-wide and extracellular anomalies. - Dont get hung up on one enzyme/protein, one cell
compartment, one gene, one epigenetic process,
one cytokine, one toxicant or infectious agent or
any single theory or model. -
5TODAYS FOCUS
- Deficient methylation of lipids adjacent to
neuronal receptors can cause loss of neuronal and
network synchrony. See Deth, Molecular Origins
of Human Attention Kluwer Acad Pub, 2003. - Methionine metabolism can be disordered in
multiple ways such that methylation is deficient,
oxidant stress occurs, and an inflammation
becomes a persistent, maladaptive condition. - Mitochondrial dysfunction is probable when
vitamin B12 (as AdoCobalamin) and carnitine are
deficient and maybe when Clostridia dysbiosis
occurs.
6TODAYS FOCUS2
- Xenobiotic (e.g. organophosphate) and elemental
(e.g. mercury) toxicants can be contributory. - Many infectious agents and foreign substances can
lead to oxidant stress when taurine is deficient. - There are nutritional aids for methylation,
reducing inflammation, mitochondrial support and
alleviating dysbiosis.

14CARNITINE
- CH3
- CH3?N? CH2?CH?CH2?COOH
- CH3 OH
15ACTIONS OF CARNITINE
- Using a translocase transporter, CARNITINE
escorts fatty acids (as fatty-acyl carnitine)
through the inner mitochondrial membrane. - Combines with excesses of organic acids
(propionic, isovaleric, 3-methylglutaric,
valproic, others) to accomplish a detoxication
function.
16REVIEW FOUR INTERRELATED PARTS OF BIOCHEMISTRY
- 1. Methionine ? SAM, methylation ?? cysteine with
some homocysteine recycle using methyls provided
by folate to Cbl on MS. - 2. Cysteine ?? taurine or cysteine ?? GSH
- Taurine scavenges OCl- GSH neutralizes H2O2
and - during cellular immune and detoxifies and
makes B12 - defense activities. work.
- 3. B12 ??GSCbl cytosolic homocysteine ?
methionine and mitochondrial cleanup of
propionate via MMA - 4. Carnitine, needs methylation for formation,
also cleans up propionate and other excess
organic acids.
17WHATS GOING WRONG?SO MUCH THAT WE HAVE TO STUDY
IT PIECEWISE
- METHIONINE ? SAM ? S-ADENOSYLHOMOCYSTEINE
- methylation
- Reduced methylation causes varying deficiencies
of - melatonin choline/TMG/DMG
- creatine methylated catecholamines
- carnitine methylated CG pairs on DNA
- methylated
fatty acids - Remedies supplements of melatonin, creatine,
L-carnitine, TMG, DMG. See ARI Publication 34.

catecholamine-stimulated methylation
19- SAH HOMOCYSTEINE (Hcy) METHIONINE
- ADENOSINE
- CYSTATHIONINE
CYSTEINE - Adenosine accumulates, SAH accumulates, SAH/SAM
ratio increases, methylation slows. Adenosine
elevated in ASD, 20 per plasma, 33 per RBCs. - Adenosine Deaminase (ADA) Binding Protein DPP4
or CD26 is inhibited by mercury, antimony, lead,
orga-nophosphates, streptokinase, casomorphin
peptides. - See Püschel et al. Eur J Biochem 126 (1982)
