Even tough differentiated spermatozoa are unable of transcriptional or translational activity;
the sperm surface undergoes major modifications in macromolecules composition during …

Sialic acids consist of a family of acidic ninecarbon sugars that are typically located at the
terminal positions of a variety of glycoconjugates. Naturally occurring sialic acids show an …

Sperm gain full ability to bind to the zona (e) pellucida (e)(ZP) during capacitation. Since
lipid rafts are implicated in cell adhesion, we determined whether capacitated sperm lipid …

Sialic acids are a family of 9-carbon monosaccharides with particular physicochemical
properties. They modulate the biological functions of the molecules that carry them and are …

Application of capillary electrophoresis (CE) in combination with mass spectrometry (MS)
and tandem MS to glycoscreening in biomedical projects is highlighted. In the first part …

Membrane lipid regulation of cell function is poorly understood. In early development, sterol
efflux and the ganglioside G M1 regulate sperm acrosome exocytosis (AE) and fertilization …

An advanced understanding of sperm function is relevant for evidence-based male fertility
prediction and addressing male infertility. A standard breeding soundness evaluation (BSE) …

Cell membranes are composed of many different lipids and protein receptors, which are
important for regulating intracellular functions and cell signaling. To orchestrate these …

A novel lectin was purified from the coelomic fluid of the sea cucumber Holothuria scabra
(HSL), subjected to bacterial challenge. HSL is a monomeric glycoprotein of molecular mass …

This review discusses identification, isolation and characterization of proteins mediating
species-selective sperm-to-egg adhesion during sea urchin fertilization. Bindin is the only …
