The protamine 1 (Prm1) and sperm mitochondria-associated cysteine-rich protein (Smcp) mRNAs exemplify a widespread pattern of mRNA-specific regulation of mRNA translation in post-meiotic spermatogenic cells, spermatids. Both mRNAs are transcribed and initially stored in free-mRNPs in early spermatids, and translated on polysomes in late spermatids. Here, we demonstrate that the ...

The oocytes of most sexually reproducing animals arrest in meiotic prophase I. Oocyte growth, which occurs during this period of arrest, enables oocytes to acquire the cytoplasmic components needed to produce healthy progeny and to gain competence to complete meiosis. In the nematode Caenorhabditis elegans, the major sperm protein hormone ...

The establishment of the dorso-ventral axis is a fundamental process that occurs after fertilization. Dorsal axis specification in frogs starts immediately after fertilization, and depends upon activation of Wnt/β-catenin signaling. The protein kinase CK2α can modulate Wnt/β-catenin signaling and is necessary for dorsal axis specification in Xenopus laevis. Our previous ...

Melasma is a commonly acquired symmetrical hypermelanosis on sun-exposed areas of the skin. The development of melasma appears to be associated with increased levels of oestrogen, exposure to sunlight and a genetic predisposition. Several in vitro studies have partially clarified the effects of oestrogen and progesterone on melasma. However, oestrogen ...
