Molecular markers of human sperm functions

Molecular Markers in Sperm Analysis

Molecular identification of infertile bulls by using newly developed DDX3Y based on human STS markers

To determine the role of DDX3Y gene in spermatogenesis and infertility in bulls, blood samples were collected from five infertile bulls (azoospermic; no sperm in the semen) at the Animal Breeding Center in Karaj, Iran. The recommended human primers by EAA/EQMN were investigated using the BLASTn database for STS marker detection. Alignment of STS marker genes with bovine genome was performed. Pr...

Molecular Markers in Neuroblastoma

Neuroblastoma, one of the common malignant childhood tumors, arises from neuroblast cells derived from theneural crest and destined for the adrenal medulla and the sympathetic nervous system and shows remarkable biologicalheterogeneity, resulting in favorable or unfavorable outcomes. Some tumors make rapid progress with a fataloutcome. In other instances, the tumors regress spontaneously in inf...

Caspase activity and apoptotic markers in ejaculated human sperm.

The objectives of this study were to determine if human ejaculated sperm exhibit active caspases and if caspase-dependent apoptosis markers are identifiable. Sperm from fertile donors and infertile patients were examined after gradient separation into leukocyte-free fractions of high and low motility. Sperm were evaluated for motion parameters, morphology, caspase activation, and apoptosis mark...

Stability, delivery and functions of human sperm RNAs at fertilization

Increasing attention has focused on the significance of RNA in sperm, in light of its contribution to the birth and long-term health of a child, role in sperm function and diagnostic potential. As the composition of sperm RNA is in flux, assigning specific roles to individual RNAs presents a significant challenge. For the first time RNA-seq was used to characterize the population of coding and ...
