Research Interests

Current research is focused on the myostatin (MSTN) gene and its role in muscle development in small ruminants. MSTN gene product, also known as growth differentiation factor (GDF8) is a member of the TGF-beta family of secreted proteins and is shown to be involved in suppressing muscle development in most animal species. Mutations in MSTN gene are known to be associated with double-muscling in cattle. Attempts to knock-out or block the expression of MSTN gene have resulted in enhanced muscular mass without any adverse noticeable effects in mice.

This research area has gained considerable interest in recent years due to its potential in the treatment of muscular dystrophy in humans and in enhancing meat production in agriculture. Our ultimate goal is to enhance muscular mass (meat) in goats by genetic manipulation of MSTN gene.

Our current study areas include:

  • Promoter regulation of MSTN gene
  • MSTN gene-targeting to produce knock-out goats
  • iPS cell development
  • Post-mortem culturability of animal cells
  • Goat genomics including molecular marker development for animal breeding.

We utilize molecular biological, reproductive, surgical and cell culture methods in our research to achieve these objectives. Our recent achievements include construction of a goat MSTN promoter-GFP reporter fusion plasmid (Fig. 1) which is being studied in in-vitro cultures. We have also established and characterized 3 fibroblast cell lines from goat tissues which are being used in studies in the lab. In addition we have recently initiated studies on post-mortem conservation of superior animal genetics at cellular level and demonstrated that fibroblast-like cells can be cultured from sheep tissues stored in regular refrigerator even upto 56 hours post-mortem. The morphology and growth characteristics of these cells were comparable to controls (Fig.2). These results are relevant for post-mortem tissue preservation for conserving desired genetics for cloning the lost animal in future as well as for tissue transplantation.
