over the past few decades, actin’s presence in the nucleus has been demonstrated. actin is a key protein necessary for different nuclear processes. although actin is well known for its functional role in dynamic behavior of the cytoskeleton, emerging studies are now highlighting new roles for actin. at the present time there is no doubt about the presence of actin in the nucleus. a number of st...

Background: Successful in vitro maturation (IVM) of oocytes is an important step for production of livestock through assisted reproductive techniques including somatic cell nuclear transfer (SCNT). Obtaining an optimal duration for maturation of oocyte is essential, since over exposure to maturation medium results in oocyte aging, while under exposure leads to production of immature incompetent...

Background: The process of wound healing involves integrated events including inflammation, granulation tissue formation, matrix deposition and remodeling. Growth factors play a key role in the process. Among them transforming growth factor-ß1 (TGF-ß1) is known to accelerate tissue repair by promoting the synthesis and deposition of extracellular matrix proteins. However, persistence or overact...
