The testis and epididymis collaborate in the male gamete development. The testis has the specific function to generate spermatozoa and spermatozoa undergo numerous changes passing through the epididymis. p63 in the basal layer of epithelium plays a key role in maintaining cellular populations, whereas Notch 1 and its ligand Jagged 2 have an important role in the cell differentiation and Jagged 2 is up-regulated by TAp63, which transactivates p53 target genes and induces apopto...

Introduction: Thyroglobulin (Tg) is stored in the follicular lumen of the thyroid and serves as a substrate of thyroid hormone biosynthesis. However, it was shown that Tg significantly induces thyrocyte cell growth and suppresses expression of thyroid-functional genes. Despite having such functions, molecular mechanisms of Tg action are largely unclear. We have recently demonstrated that TSH-induced thyroid cell growth is partly mediated by a downregulation of microRNAs (miRNA...
