The switch in gene expression that accompanies

A number of growth factors secreted by Sertoli cells including . (IGF-I), . (TGF-β), and interleukin-1 are proposed to influence germ-cell functions by interacting with their cognat

During the early stages of meiotic prophase, a relatively low rate of [.H]uridine incorporation was detected; however, RNA synthesis increases at the mid-pachytene stage followed by diminution during the meiotic divisions. RNA synthesis once again increases in the round and el

Ligand binding is essential for activation of the receptor, which then binds to specific targets on DNA resulting in modulation of the level

As details about the structure and biochemistry of vitamin A have been revealed, it has become clear that a family of compounds, the retinoids, are involved in fulfilling the functions of vitamin A. Retinol is the only “required” retinoid because it can serve as a precursor to all
