Article Title: Anoctamin 6 Regulates C2C12 Myoblast Proliferation
Abstract: Anoctamin 6 (Ano6) belongs to a conserved gene family (TMEM16) predicted to code for eight transmembrane proteins with putative Ca2+-activated chloride channel (CaCC) activity. Recent work revealed that disruption of ANO6 leads to a blood coagulation defect and impaired skeletal development. However, its function in skeletal muscle cells remains to be determined. By using a RNA interference mediated (RNAi) loss-of-function approach, we show that Ano6 regulates C2C12 myoblast proliferation. Ano6 is highly expressed in C2C12 myoblasts and its expression decreases upon differentiation. Knocking down Ano6 significantly reduces C2C12 myoblast proliferation but has minimal effect on differentiation. Ano6 deficiency significantly reduces ERK/AKT phosphorylation, which has been shown to be involved in regulation of cancer cell proliferation by another Anoctamin member. Taken together, our data demonstrate for the first time that Ano6 plays an essential role in C2C12 myoblast proliferation, likely via regulating the ERK/AKT signaling pathway.
