Project description:Analysis of changes in skeletal muscle myoblasts in response to over-expression of angiopoietin-1 (Ang-1) and angiopoietin-2 (Ang-2). The hypothesis tested in the present study was that over-expression of Ang-1 or Ang-2 will induce the expression of pro-survival and pro-differentiation genes in skeletal myoblasts while inhibiting the expression of pro-apoptotic genes. Results provide important information of how mRNA profile of skeletal myoblasts is altered by Ang-1 and ang-2 and provide first evidence that secondary mediators such as leptin may mediate the enhancement of skeletal myoblasts differentiation by Ang-1 and Ang-2. Total RNA obtained from isolated human skeletal myoblasts after 48hrs of infection with adenoviruses expressing GFP (control), Ang-1 or Ang-2.

Project description:Cancer cachexia is a metabolic syndrome with alterations in gene expression profile that consequently lead to skeletal muscle wasting. Here, we used RNA sequencing to analyze the mRNA expression profile in the tibialis anterior muscles of the Lewis lung carcinoma (LLC) model of cancer cachexia.
