Evaluation of correct endogenous reactive oxygen species content for human sperm capacitation and involvement of the NADPH oxidase system.
BACKGROUND Generation of controlled amounts of reactive oxygen species (ROS) and phosphorylation of protein tyrosine residues (Tyr) are two closely related changes involved in sperm capacitation. This study investigated the effect of altered endogenous ROS production on Tyr-phosphorylation (Tyr-P), acrosome reaction (AR) and cell viability during sperm capacitation. The possible origin of the a...
متن کاملInvolvement of Activation of Nadph Oxidase
ABSTRACT Zinc is employed as a supplement; however, zinc-related nephropathy is not generally known. In this study, we investigatecl zinc-induced renal cell iajury using a pig kidney-derived cultured renal epithelial cell line, LLC-PKI, with proximal kidney tubule-like features, and examined the involvement of free radicals and extracellular signal-regu]ated kinase (ERK) in the cell injury. The...
متن کاملProteins implicated in sperm capacitation.
Spermatozoa after being deposited in the female reproductive tract spend a considerable time in this foreign environment prior to fertilization of the oocyte. Chang and Austin independently observed1,2 that this time spent by the spermatozoa in the female tract is not consequential but a necessary event in the life cycle of the male gamete, and Austin2 first called this maturation period of spe...
متن کاملLeptin and leptin receptor in pig spermatozoa: evidence of their involvement in sperm capacitation and survival.
Several studies have recently investigated the role of leptin, the adipocyte-secreted hormone, in the growth and reproduction of rodents, humans, and domestic animals. The present study was designed to explore the expression of leptin and its receptor in pig spermatozoa. Successful Western blot evidenced a 16 kDa band for leptin and six isoforms, ranging from 120 to 40 kDa, for the leptin recep...
متن کاملInvolvement of NADPH oxidase in age-associated cardiac remodeling
Increased activation of the renin-angiotensin-aldosterone system (RAAS) and an increase in oxidative stress are both implicated in age-related cardiac remodeling but their precise interrelationship and linkage to underlying molecular and cellular abnormalities remain to be defined. Recent studies indicate that NADPH oxidases are major sources of oxidative stress and are activated by the RAAS. T...
