Electroacupuncture Raises Energy Levels In Chronic Fatigue Syndrome Model!

PGC-1 is a transcription coactivator that is responsible for a number of regulatory functions of cellular metabolism. It stimulates mitochondrial biogenesis and promotes muscle fiber type that is metabolically more oxidative than glycolytic which is about 15 times more efficient. It is present in high amounts where mitochondria is present like brown fat, the heart and muscle. Increased transcription of PGC-1 induces Nrf1 and Nrf2 to increase expression of mitochondrial transcription factors and other mitochondria subunits along the transport like ATP-synthase. (1)

While the cause of chronic fatigue is not known, many experts believe that symptoms of fatigue may be due to mitochondrial dysfunction where the muscles produce less energy. One study in Great Britain demonstrated that 70% of chronic fatigue syndrome (CFS) patients   have ultra structurally abnormal mitochondria.  (2)In a more recent study published just last month, researchers analyzed the benefits of electroacupuncture (EA) ST-36 on the metabolism of CFS-model in rats. They divided the mice into 4 groups; the control group, the CFS-model mice, an EA-"Zusanli" and a non-""Zusanli group. Measurements for ATP-synthase, PGC-1, AMPK and SIRT1 were taken. After forced exercise, the levels of ATP-synthase and PGC-1 were greatly reduced while levels of SIRT1 were elevated. After an application of  electroacupuncture, "the grabbing force and the expression levels of ATP synthase mRNA, SIRT 1 and PGC-1 α proteins and mRNAs, and p-AMPK/AMPK were significantly up-regulated. The results seem to show that the grabbing force of the rats after EA was due to the increased levels of ATP-synthase,  AMPK, PGC-1 and SIRT1 to reduce mitochondrial oxidative stress and to increase energy ATP.

Chronic Fatigue: The Nrf2 and Mitochondrial Connection

Chronic fatigue syndrome (CFS) is a condition where symptoms last more than 6 months. One identifying feature is that the overwhelming fatigue that comes with it is not resolved with rest. CFS is now recognized as a serious health condition that is known to effect the immune and neurological systems and have other physiological impacts. In my posts, I often classify CFS as an environmental illness for the sake of simplicity. I also consider multiple chemical sensitivity (MCS) and fibromyalgia (FM) as environmental illnesses. What is common in most patients with these illnesses, is that they have higher than normal levels of oxidative stress. Oxidative stress is produced by natural cellular processes or exposure to environmental toxicants. At high levels it leads to tissue damage and disease.  Currently, the true cause of these environmental illnesses are not known. 

While the cause of CFS might not be known, several theories have been proposed. One such theory is that mitochondrial dysfunction leads to the rampant increase of oxidative stress and overall, energy depletion. (1) This in turn leads to other inflammatory processes. Of course, the opposite could be true. In general, I believe that the inhibition of the Nrf2 pathway is at the root of environmental illness. The Nrf2 is a master gene regulater that regulates the natural antioxidant system in cells and neutralizes oxidative stress. It can be inhibited by many factors including TNF-a and abnormal methylation and xenobiotics. It is upregulated by natural phenols like EGCG, sulforaphane in broccoli, resveratrol and quercetin to name a few. Recent discoveries have also lead to a number of pharmaceuticals that increase expression of Nrf2. It is only in the past few years that researchers have identified a number of ways that the Nrf2 pathway promotes cellular respiration, ATP synthesis and provides other functions in the mitochondria. 

So how exactly does Nrf2 function in the mitochondria? It seems it does it in a number of ways including reducing oxidative stress by promoting the action of complex 1, regulating the expression of ATP synthase subunit α, allows for more efficient oxidative phosphorylation, increases the levels of ATP, there is better integration of fatty acid oxidation with the TCA cycle (a process that occurs through the action for example, of glucoraphanin which is the precursor of the classical Nrf2 activator sulforaphane ), it promotes biogenesis, increases PGC-1 and maintains mitochondrial integrity. (2)

While it is not known if mitochondrial dysfunction occurs in all environmental illnesses, it makes sense that it might be a possibility. In any case, there is a reason to believe that energy depletion from oxidative stress may be a factor in causing some symptoms.

Fatigue as a Consequence of Changes In Cellular Metabolism and Disturbed Sleep!

In a recent article the author writes, "persistent fatigue may be a consequence of chronic low-grade inflammation leading to an imbalance in energy availability and expenditure, which can be mediated and maintained by changes in circadian rhythms and sleep. He goes on to say that associations between persistent fatigue in CFS and CRF with alterations in cellular metabolism, disturbed sleep, and, to a lesser extent, disruptions in circadian rhythm. For both CRF (cancer-relate fatigue) and CFS, multi-causal models are generally suggested including low-grade inflammation and disturbed sleep, and also alterations in stress physiological responses, genetic vulnerability, and sociodemographic factors, among others.
