Probing the Biological Plausibility of Fluoride as an Endocrine Disruptor

open access: yesBirth Defects Research, Volume 118, Issue 5, May 2026.
ABSTRACT Background Fluoride has come under recent scrutiny regarding concerns over potential neurodevelopmental and endocrine‐related toxicities, with recent reviews by the National Toxicology Program (NTP) and European Food Safety Authority (EFSA) concluding with moderate or reasonable confidence, respectively, that exposure to drinking water having ...

A microRNA cluster in the Fragile-X region expressed during spermatogenesis targets FMR1. [PDF]

open access: yes, 2019
Testis-expressed X-linked genes typically evolve rapidly. Here, we report on a testis-expressed X-linked microRNA (miRNA) cluster that despite rapid alterations in sequence has retained its position in the Fragile-X region of the X chromosome in ...

RNA Modifications: Current Understandings and Future Perspectives

open access: yesMedComm, Volume 7, Issue 5, May 2026.
Types of RNA modification. We have summarized the currently common types of RNA modifications, including ac4C, m6A, m1A, m5C, m3C, m7G, and ψ, and visually characterized their features through structural formulas. The characteristic structures are marked with a background color different from the background color.

Establishment of a normal medakafish spermatogonial cell line capable of sperm production in vitro [PDF]

open access: yes, 2004
Spermatogonia are the male germ stem cells that continuously produce sperm for the next generation. Spermatogenesis is a complicated process that proceeds through mitotic phase of stem cell renewal and differentiation, meiotic phase, and postmeiotic ...

Histone Modifications in Cardiovascular Disease: Mechanisms and Therapeutic Opportunities

open access: yesMedComm, Volume 7, Issue 5, May 2026.
This graphical abstract summarizes how classical and emerging histone posttranslational modifications (PTMs), together with their chromatin regulators (writers, erasers, and readers), govern major pathobiological programs in cardiovascular disease.

High‐Resolution Imaging Reveals Mitochondrial Protein Imbalance in Sperm of Oligoasthenospermic Men

open access: yesMolecular Reproduction and Development, Volume 93, Issue 5, May 2026.
ABSTRACT Male infertility accounts for nearly half of global infertility cases and is often linked to poor sperm quality, such as oligospermia, asthenospermia, and teratospermia. Although the exact mechanisms remain unclear, mitochondria, which are critical for ATP production and reactive oxygen species generation during fertilization, are increasingly

Use of Pentoxifylline to Improve Seminal Parameters in Dogs

open access: yesVeterinary Medicine and Science, Volume 12, Issue 3, May 2026.
A single oral dose of pentoxifylline (10 mg/kg) administered 40 min before ejaculation significantly improved sperm concentration and progressive motility in dogs. The effect was most pronounced in oligospermic subjects, supporting pentoxifylline as a rapid, well‐tolerated adjunct therapy for canine subfertility .

Kisspeptin as a test of hypothalamic dysfunction in pubertal and reproductive disorders

open access: yesAndrology, Volume 14, Issue 4, Page 1002-1016, May 2026.
Abstract The hypothalamic–pituitary–gonadal axis is regulated by the gonadotropin‐releasing hormone pulse generator in the hypothalamus. This is comprised of neurons that secrete kisspeptin in a pulsatile manner to stimulate the release of GnRH, and, in turn, downstream gonadotropins from the pituitary gland, and subsequently sex steroids and ...
