Behavioral mechanisms of mammalian sperm guidance
In mammals, sperm guidance in the oviduct appears essential for successful sperm arrival at the oocyte. Hitherto, three different potential sperm guidance mechanisms have been recognized: thermotaxis, rheotaxis, and chemotaxis, each of them using ...

IAPs as E3 ligases of Rac1 : shaping the move [PDF]
Inhibitors of Apoptosis Proteins (IAPs) are well-studied E3 ubiquitin ligases predominantly known for regulation of apoptosis. We uncovered that IAPs can function as a direct E3 ubiquitin ligase of RhoGTPase Rac1.

The Karyopherin proteins, Crm1 and Karyopherin β1, are overexpressed in cervical cancer and are critical for cancer cell survival and proliferation [PDF]
AbstractThe Karyopherin proteins are involved in nucleo‐cytoplasmic trafficking and are critical for protein and RNA subcellular localization. Recent studies suggest they are important in nuclear envelope component assembly, mitosis and replication. Since these are all critical cellular functions, alterations in the expression of the Karyopherins may ...

One of the most common lesions present in the spermatozoa of human infertility patients is an idiopathic failure of sperm-egg recognition. Although this unique cellular interaction can now be readily by-passed by assisted reproductive strategies such as ...

Developmental regulation of the heat shock response by nuclear transport factor karyopherin-α3 [PDF]
During early stages of Drosophila development the heat-shock response cannot be induced. It is reasoned that the adverse effects on cell cycle and cell growth brought about by Hsp70 induction must outweigh the beneficial aspects of Hsp70 induction in the

Health Benefits and Therapeutic Potential of Quercetin
Quercetin, a polyphenolic compound prevalent in many fruits, vegetables, and other dietary sources, has attracted considerable interest due to its extensive health benefits. This review examines its diverse biological properties, particularly its antioxidant and anti‐inflammatory effects. The study integrates recent scientific findings to elucidate the

Evolutionary and Transcriptional Analysis of Karyopherin β Superfamily Proteins [PDF]
In eukaryotes, karyopherin beta superfamily proteins mediate nucleocytoplasmic transport of macromolecules. We investigated the evolutionary and transcriptional patterns of these proteins using bioinformatics approaches. No obvious homologs were found in prokaryotes, but an extensive set of beta-karyopherin proteins was found in yeast.

A comparative evaluation of semen parameters in pre- and post-Hurricane Katrina human population
A natural disaster leading to accumulation of environmental contaminants may have substantial effects on the male reproductive system. Our aim was to compare and assess semen parameters in a normospermic population residing in the Southern Louisiana, USA

Identification of a Small Molecule Inhibitor of Importin β Mediated Nuclear Import by Confocal On-Bead Screening of Tagged One-Bead One-Compound Libraries [PDF]
In eukaryotic cells, proteins and RNAs are transported between the nucleus and the cytoplasm by nuclear import and export receptors. Over the past decade, small molecules that inhibit the nuclear export receptor CRM1 have been identified, most notably ...
