Dataset: PGC-1 alpha isoforms and muscle hypertrophy

An alternative promoter of the PGC-1 alpha gene gives arrise to 3 new isofroms of the PGC-1 alpha gene refered to as PGC-1a2 (A2), PGC-1a3 (A3) and PGC-1a4 (A4). The proximal PGC-1 alpha promotor transcribes the canonical PGC-1 alpha which is refered to as PGC-1a1 (A1).G1/G2/G3 samples refer to the Green fluorescent protein (GFP) control samples used in this experiment. Forced expression of specifically PGC-1a4 isoform results in muslce hypertrophy associated with increased IGF-1 signaling and repression of myostatin signaling. Adnoviral over expression assays were performed on primary myoblasts from C57BL/6 mice for each of the PGC-1 alpha isoforms originating from the proximal or alternative promotor.
