Seminal fluid harbours the as yet unknown mechanism that facilitates rapid adjustment of sperm velocity in response to changing sperm competition risk.
Nematode sperm respond to competitive environments by modulating cellular pathways involved in migration and storage to ensure their access to oocytes.
A seminal protein from a mating-male can bind sperm previously stored in his mate, providing direct benefits to the sperm from the prior male that mated with her.
The engagement of DNA crossings is shown to license ATP hydrolysis and DNA cleavage by topoisomerase VI, a finding with mechanistic ramifications for related GHKL ATPases and meiotic recombination machineries.
GDC-0810 is a novel, orally bioavailable SERD that exhibits robust pre-clinical activity in models of ER+ breast cancer, including models of tamoxifen resistance, and those that express the ERα mutations, ER.Y537S and ER.D538G.
Nuclei and spatial system dimensions control local concentrations of cell cycle regulators, determining the spatial origin of waves that coordinate DNA replication and, subsequently, cell division.
The slope of the chemoattractant concentration gradient is a driving force for sperm chemotaxis, by coordinating the entrainment of information flow between sensing, signaling and motility.
