Chronic Fatigue Syndrome (CFS) and Fibromyalgia Syndrome (FMS) are disorders which their symptoms and treatments are not clearly known. CFS and FMS are not life threatening diseases; however, they can affect patients’ quality of life because they experience symptoms including exercise intolerance, need for bedrest, and debilitating chronic pain and fatigue with these disorders. The research from Dr. Light’s lab has shown that moderate exercise for 25 minutes causes changes in mRNA levels in CFS and FMS patients but not healthy controls. The objective of our study was to examine changes in white blood cell gene expression of CFS and FMS patients both on Lyrica and on placebo in a double-blinded, cross-over design (where each study subject was his or her own control) by using quantitative PCR gene expression analysis. The lab routinely analyzes blood samples for 48 different genes from study subjects and healthy controls collected before (baseline) and then 8, 24, 48 hours after exercise moderate exercise. My focus was on changes in expression of two ATP-responsive purinergic receptors, P2X7 and P2Y1, which have not been studied after exercise in CFS and FMS but have been associated with chronic inflammation and pain in animal models. White blood cell layers (buffy coat) were collected from samples, RNA was extracted and converted to cDNA. 384 well PCR plates were robotically loaded from 96 well source plates, then the PCR reaction was run in an ABI 7900 thermal cycler that tracks fluorescence in “real time” (real time qPCR). Analysis of results is in progress and will be reported on the poster.
