Impact of Endocrine‐Disrupting Chemicals (EDCs) Used in the Food Industry on Endocrine Abnormalities

Food Safety and Health, EarlyView.
This review was conducted to examine the relationship between hormone disruption and other endocrine abnormalities in the context of the constant consumption of genetically modified foods and overexposure to chemicals used directly and indirectly in the agrifood industry.

E3 Siah ubiquitin ligase regulates dichotomous spermatogenesis in Sitotroga cerealella

Frontiers in Cell and Developmental Biology
Spermatogenesis in Lepidoptera holds significant importance due to its unique process of dichotomous spermatogenesis, yielding eupyrene and apyrene spermatozoa through a complex molecular mechanism.

Deficiency of Mkrn2 causes abnormal spermiogenesis and spermiation, and impairs male fertility. [PDF]

, 2016
Although recent studies have shed insights on some of the potential causes of male infertility, new underlining molecular mechanisms still remain to be elucidated.

Pregnancy via Testicular Sperm Extraction for Anejaculation After Neuroblastoma Surgery

IJU Case Reports, EarlyView.
ABSTRACT Background Surgical treatment of a neuroblastoma, a malignant tumor of the sympathetic nervous system, may result in ejaculatory disorder. There are no reports examining ejaculation disorders after neuroblastoma surgery. Case Presentation The patient was a 31‐year‐old Japanese male who had undergone surgery for neuroblastoma of the abdomen at ...

A CRISPR-Cas9 sex-ratio distortion system for genetic control. [PDF]

, 2016
Genetic control aims to reduce the ability of insect pest populations to cause harm via the release of modified insects. One strategy is to bias the reproductive sex ratio towards males so that a population decreases in size or is eliminated altogether ...

Epigenetics and oxidative stress: A twin‐edged sword in spermatogenesis

Andrologia, 2019
Spermatogenesis is a series of complex events involving a delicate balance between cell proliferation and cell differentiation. Aggregation of chromatins and epigenetic modifications play a vital role in spermatogenesis via regulation of molecular ...

Pyriproxyfen Disrupts the Ongoing Spermatogenesis Wave in Danio rerio Potentially Mediated by Voltage‐Dependent Calcium Channels and Protein Kinase C

Journal of Applied Toxicology, EarlyView.
ABSTRACT Pyriproxyfen (PPX) is an analog of the juvenile hormone from insects. Following our previous studies, for the ex vivo short‐term effect, we chose 10−9 M pyriproxyfen to analyze the morphology of spermatogenesis wave cells. In silico docking and ADMET (Absorption, Distribution, Metabolism, Excretion, Toxicity) studies were carried out to ...

Androgen-induced rhox homeobox genes modulate the expression of AR-regulated genes [PDF]

, 2010
Rhox5, the founding member of the reproductive homeobox on the X chromosome (Rhox) gene cluster, encodes a homeodomain-containing transcription factor that is selectively expressed in Sertoli cells, where it promotes the survival of male germ cells ...

Formation and function of the manchette and flagellum during spermatogenesis.

Reproduction, 2016
The last phase of spermatogenesis involves spermatid elongation (spermiogenesis), where the nucleus is remodeled by chromatin condensation, the excess cytoplasm is removed and the acrosome and sperm tail are formed.
