Extracellular stimuli elicit changes in gene expression in target cells by activating intracellular protein kinase cascades that phosphorylate transcription factors within the nucleus. One of the best characterized stimulus-induced transcription factors is cyclic AMP (cAMP) responsive element binding ...

There are two families of transcription factors that play pivotal roles during mammalian skeletal muscle differentiation. One of them includes MyoD family proteins (also called myogenic regulatory factors or MRFs), with four members Myf5, Myogenic differentiation 1 (MYOD), Myogenin (MYOG), ...

Myocyte enhancer factors 2 (MEF2) is a family of muscle-enriched transcription factors that have an essential role in myogenesis. In addition, MEF2 is also expressed at high levels in neurons and lymphocytes, where it serves as a regulator of neuronal and immune cell differentiation ...

Osteoporosis is a common disease affecting the majority of older women and a significant minority of older men. It is defined as the gradual reduction in bone strength with advancing age, particularly in post-menopause women. Osteoporosis is one of the major and growing health care problems around ...
