de Vega et al showed that the most hypermethylated gene associated with quality of life in ME patients was GRAMD1A. A hypermethylated gene is often associated with supressed transcription (2).
GRAMD1A promotes the expansion of hepatocellular carcinoma stem cell and hepatocellular carcinoma growth through STAT5 (3).
If up-regulated GRAMD1A up-regulates STAT5 and induces growth in cancer cells, what do a down-regulated GRAMD1A do in ME patients? In liver cells? In lymphocytes?
STAT5 is involved in lymphocyte development and transformation. And STAT5 promotes the proliferation, survival and selfrenewal of hematopoietic stem cells (ref 21-24 in ref 3).
