Research Abstract

The research focused on the formation of muscle-tendon structure complex, which is essential for motor function. RP58, a transcription factor required in the development of muscle and Mkx, essential in normal growth of tendons and ligaments were investigated. In order for to determine the mechanism for Mkx expression, promoter/enhancer region of Mkx was localized and 3 candidate transcription factors were identified. Mkx regulated genes were also investigated and identified. RP58 is known to bind to DNMT3, a de novo DNA methyltransferase, and hence DNA methylation was analyzed genome-wide and regions of methylation activity were identified.
