Zebrafish dmrta2 Regulates the Expression of cdkn2c in Spermatogenesis in the Adult Testis

, 2013
The exact function of the doublesex and mab-3 related transcription factor-like family a2 gene (dmrta2) has remained largely unknown possibly because of its functional redundancy with dmrta1 in most vertebrates.

Minimally Invasive Sampling for Molecular Profiling of Lymph Nodes Using a Modified Acupuncture Needle

iMetaMed, EarlyView.
Schematic illustration of the preparation of His@PDA@Needle, a modified acupuncture needle designed for minimally invasive sampling of lymph node‐derived DNA for molecular profiling. ABSTRACT Current clinical liquid biopsy approaches predominantly rely on blood‐derived biomarkers, which are often limited in sensitivity.

Induction of Spermatogenesis and Its Predictors in Men with Prepubertal-Onset Hypogonadotropic Hypogonadism Undergoing Gonadotropin Therapy

The World Journal of Men's Health
Purpose: To evaluate the outcomes of gonadotropin therapy (GT) using human chorionic gonadotropin (hCG) and recombinant follicle-stimulating hormone (rFSH) for inducing spermatogenesis in men with prepubertal-onset hypogonadotropic hypogonadism (HH ...

Impacts of morphine addiction on spermatogenesis in rats

Iranian Journal of Reproductive Medicine, 2016
Background: There are numerous investigations on wide range of issues that disrupt regulatory spermatogenesis, individuals who are exposed to drug abuse faced infertility and immature spermatogenesis. Objective: The aim of this study was to evaluate the

N6‐Methyladenosine in Inflammatory Bowel Disease: An Emerging Regulator of Pathogenesis and a Novel Therapeutic Frontier

iMetaMed, EarlyView.
Inflammatory bowel disease (IBD) is a chronic inflammatory disorder of the intestine associated with an imbalance in intestinal homeostasis. m6A‐modifying enzymes, consisting of m6A writers, erasers and readers, plays a pivotal role in the pathogenesis and progression of IBD by affecting four intestinal barriers, including the intestinal mechanical ...

Nonclassical Testosterone Signaling:A New Pathway Controlling Spermatogenesis? [PDF]

, 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 ...

Nanoplastics: Methods, Exposure and Effects on Domestic, Farm and Wild Animals

Journal of Applied Toxicology, EarlyView.
ABSTRACT Nanoplastics (NPs) are synthetic polymer particles ranging in size from 1 nm to 1 μm that have been identified as a major concern for ecosystems and organisms due to their plethora of negative effects. The aim of this review is to provide a comprehensive overview of the knowledge relating to exposure and effects of NPs in domestic (i.e., farm ...

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.

Redox‐Associated Renal and Male Reproductive Alterations Following Dexamethasone Exposure in Male Rats: Histopathological and Spermatological Evaluations

Journal of Applied Toxicology, EarlyView.
ABSTRACT Dexamethasone (DEX) is widely used in clinical practice, although it may also cause oxidative stress–related damage in different tissues, including the kidney and male reproductive system. This study investigated DEX‐induced renal and reproductive injury in rats and evaluated the modulatory effect of reduced glutathione on DEX‐associated redox

Low‐Dose Chlorothalonil Induces Testicular Injury Through Disruption of Steroidogenic Signaling in Adult Male Mice

Journal of Applied Toxicology, EarlyView.
ABSTRACT Chlorothalonil (CHL) is a widely used organochlorine fungicide frequently detected in environmental and food matrices. Although increasing evidence indicates adverse effects in nontarget species, the mechanisms underlying CHL‐induced male reproductive toxicity remain incompletely understood.
