Online published on 18 July, 2018. Abstract Transgenic food animal production is one of the potential and need oriented research to mitigate the food crises of the world. In vitro gene silenced animal cells and making use of these cells for transgenesis one of the suitable way to produce productive animals. Myostatin is a negative regulator of muscle growth, has the potential to increase the muscle mass upon its silencing. Four Hush 29-mer anti-myostatin (MSTN) shRNA constructs were checked for myostatin gene silencing in caprine foetal fibroblast cells and its subsequent effect on basic helix-loop-helix (bHLH) transcription factors. These factors are necessary for the terminal differentiation, proliferation, and homeostasis of muscle development. Different shRNA constructs displayed 55.1 to 91.5% (p < 0.01) of myostatin silencing in caprine foetal fibroblast cells and upregulation of myogenic gene. Upregulation of 7.97 to 111.67% for MyoD, 77.0% to 319.47% for myogenin, 16.67% to 138.0% for Myf5 were observed. The Pearson correlation established a negative correlation between myostatin and genes under study. Result suggests that knockdown of MSTN a potential approach to improve caprine musculatures.
