Rho GTPases and spermatogenesis
, 2003 Rho GTPases, such as Rho, Rac and Cdc42, are known to regulate many cellular processes including cell movement and cell adhesion. While the cellular events of germ cell movement are crucial to spermatogenesis since developing germ cells must migrate ...

Evaluation of Potential Hormonal Activities of Ashwagandha (Withania somnifera)
Phytotherapy Research, EarlyView.ABSTRACT Ashwagandha is a widely used herb in traditional medicine systems, particularly Ayurveda. Despite its extensive tradition, growing concerns regarding its potential endocrinological effects have prompted scientific scrutiny. This review systematically evaluates the current preclinical, clinical, and case study evidence concerning AS's effects ...

Human spermatogenesis and its regulation
, 2017 Spermatogenesis in humans is comprised of a series of highly complicated cellular events, necessary to support the production of an upward of 200 million sperm daily from puberty through the entire adulthood of a healthy man. Recent advances in the field

Environmental Toxicology, EarlyView.ABSTRACT Pesticides and pharmaceuticals are among the most common chemical groups in waterbodies and soils, and their universal distribution raises concerns about potential adverse effects on nontarget organisms and humans. Reproductive output disruption is of particular concern, as it transposes effects from the individual to the next generations at ...

LncRNA4667 is dispensable for spermatogenesis and fertility in mice
Reproductive and Developmental Medicine, 2019 Objective: Spermatogenesis is a complex process which is of vital importance for sexual reproduction. In many studies of spermatogenesis, the mRNAs, protein-coding genes, as well as small noncoding RNAs (ncRNAs) have been well characterized.

Environmental Toxicology, EarlyView.ABSTRACT Bisphenol A (BPA), its structural analogs, and phthalates are synthetic chemicals widely used, with documented endocrine‐disrupting activity. This study aimed to develop and validate a selective multiresidue analytical method for the simultaneous determination of BPA, 10 bisphenol analogs, and six phthalates in PET‐bottled mineral water.

Environmental Toxicology, EarlyView.ABSTRACT Mining plays a crucial role in economic development, but improper management can lead to severe environmental degradation. Particularly for iron ore, mining generates vast amounts of tailings often stored in unstable dams. This study aims to investigate the toxicological impacts of environmentally relevant concentrations of metals mixture ...

Nonclassical Testosterone Signaling:A New Pathway Controlling Spermatogenesis?
, 2016 Testosterone is the essential regulator of spermatogenesis [1]. Produced by the testicular Leydig cells in response to pituitary Luteinizing Hormone (LH) stimulation, testosterone mediates its effects by binding to its cognate receptor, the ligand ...
