PURPOSE: Alcoholism is a heterogeneous set of disorders caused by ethanol intake. Harmful effects of paternal consumption on the offspring are poorly explored and not fully understood. We analyzed the effect of paternal alcohol consumption on both th

Purpose: To investigate whether the ability of human spermatozoa to decondense in vitro in the presence of heparin (Hep) and glutathione (GSH) is related to assisted reproduction (ART) success. Methods: Cross-sectional pilot study involving male part

In bovine, intracytoplasmic sperm injection (ICSI) remains inefficient partially due to low levels of sperm decondensation. The aim of this study was to determine whether the injection of normal size sperm pretreated with heparin (Hep) and L-glutathi
During sperm development, a highly condensed chromatin is formed due to the replacement of histones by other positively charged proteins: the protamines. This renders a stable yet transcriptionally inactive DNA which is carried by sperm to the fertil

El núcleo del espermatozoide de mamíferos contiene la cromatina inusualmente condensada, gracias al reemplazo de la mayoría de las histonas por otras proteínas básicas llamadas protaminas. Sin embargo, apenas el espermatozoide penetra el ooplasm

BACKGROUND: Human sperm nuclear decondensation in vivo involves protamine disulfide bond reduction by glutathione (GSH) and protamine/histone exchange, presumably with heparan sulfate (HS) as the protamine acceptor. The aim of the present study was t

Background: Human spermatozoa decondense in vitro upon exposure to heparin and glutathione. Glutathione is also the disulfide bond reducer in vivo, and heparan sulfate, a functional analogue of heparin, has been proposed as the protamine acceptor. Th

Reduced glutathione (GSH) is an endogenous disulfide bond reducer present in mammalian oocytes. It plays a critical role in sperm decondensation following fertilization, disrupting the protamine bonds that sustain the hypercondensed state of sperm DN

Purpose To analyze the presence of various histone modifications in ejaculated human spermatozoa Methods In this prospective study, seminal ejaculates from 39 normozoospermic individuals were evaluated for semen analysis and the presence of histone m

We have previously described enhanced human breast cancer cell proliferation and mouse mammary tumor growth induced by α(2)-adrenoceptor (α(2)-AR) expression in epithelial cells. The aim of the present work was to assess if stromal fibroblasts can
