چکیده

Mitochondria activation factor (MAF) is a high-molecular-weight polyphenol purified from black tea that activates mitochondrial respiration. It increased the mitochondrial membrane potential and motility of sea urchin sperm, by up to 8%, to the same extent as sperm-activating peptides (SAPs) secreted by the egg. Unlike SAPs, MAF had no effect on sperm swimming behavior, suggesting that the mechanism of sperm activation by MAF is different from that of SAPs.

Structure, function and biosynthesis of sperm-activating peptides and fucose sulfate glycoconjugate in the extracellular coat of sea urchin eggs.

A decapeptide (GFDLNGGGVG) isolated from the solubilized jelly layer of the sea urchin Hemicentrotus pulcherrimus stimulates the respiration and motility of H. pulcherrimus spermatozoa and, in addition, produces a number of biological effects on H. pulcherrimus spermatozoa including increases in cAMP and cGMP levels, activation of a Na+/H+ exchange system, and increases in intracellular pH (pHi...

A cytosolic sperm protein factor mobilizes Ca2+ from intracellular stores by activating multiple Ca2+ release mechanisms independently of low molecular weight messengers.

Ca2+ oscillations can be induced in mammalian eggs and somatic cells by microinjection of a cytosolic sperm protein factor. The nature of the sperm factor-induced Ca2+ signaling was investigated by adding sperm protein extracts to homogenates of sea urchin eggs, which contain multiple classes of Ca2+ release mechanisms. We show that the sperm factor mobilizes Ca2+ from non-mitochondrial Ca2+ st...

Metabolism of sea urchin sperm. Interrelationships between intracellular pH, ATPase activity, and mitochondrial respiration.

Mitochondria of sperm of the sea urchin Strongylo-centrotus purpuratus are tightly coupled before induction of the acrosomal reaction. When the sperm are diluted at low external pH (pH 5.5) or in high potassium (200 mM) or in the absence of sodium, their internal pH is acidic (6.2-7.0) as measured by amine accumulation. Under these conditions the internal ATPase activity (primarily the dynein A...

Atp-induced Sliding of Microtubules in Bull Sperm Flagella

ATP-induced sliding of doublet microtubules has been recently demonstrated with axonemes of sea urchin sperm flagella which had been briefly digested with trypsin (13) . The specific chemical conditions in which such sliding occurs are the same as those required for the reactivation of beating in demembranated sea urchin sperm cells (4) . The conclusion from these observations, that the bending...

Relationship between sperm ATP content and motility of carp spermatozoa.

Carp spermatozoa are immotile in seminal plasma or in saline solution of high osmolality (> 400 mosmol kg-1). These 'quiescent' spermatozoa initiate a progressive forward motility when transferred in freshwater or in saline solution with low osmolality (< 160 mosmol kg-1). In this study we investigated 'in vitro' the relationship between sperm ATP content (measured by bioluminescence) and sperm...
