SOX30 Governs Synaptonemal Complex Assembly and Homologous Recombination in Male Meiosis

Cell Proliferation, EarlyView.
The transcription factor SOX30 directly binds promoter regions of SYCE1 and SYCE2 to mediate their transcriptional activation, thereby enabling proper assembly of central elements within the synaptonemal complex. Structural destabilisation of the synaptonemal complex in Sox30 KK spermatocytes triggers synaptic discontinuity, impairs homologous ...

Diagnostic yield of OCT3/4 reflex testing in testicular biopsy

Histopathology, EarlyView.
GCNIS detection frequency was 48/3353 (1.4%) testicular biopsies from 42/1870 (2.2%) men who underwent testicular biopsy with or without testicular sperm extraction (TESE). OCT3/4 was particularly helpful for detecting interstitial seminoma, GCNIS coexisting with mature spermatogenesis, and focal GCNIS.

In vitro and in vivo studies on the effect of a mitochondrial fusion promoter on Leydig cell integrity and function

Frontiers in Toxicology
Background: The interstitial testicular Leydig cells are responsible for the production of testosterone, which functionally deteriorate with normal aging.

Auto‐inducible expression of chimeric antigen receptor T cells using the NR4A1 promoter

Immunology &Cell Biology, EarlyView.
The NR4A1 promoter is a compact auto‐inducible promoter to drive CAR expression in T cells. Compared with EF1α, or existing synthetic antigen‐inducible promoters, NR4A1 is more compact and ensures that resting CAR T cells express reduced baseline CAR. NR4A1 allows rapid induction upon antigen encounter with reduced T‐cell exhaustion.

Pharmacokinetics of Topical Administration of Altrenogest in Mares and Implications for Human Health

Journal of Veterinary Pharmacology and Therapeutics, EarlyView.
ABSTRACT Altrenogest is a synthetic progestogen widely used in equine reproductive management. Adverse effects to altrenogest have been reported in people with cutaneous exposure reported as the highest exposure pathway. Despite these reports, there has been no quantitative research to determine the capacity for altrenogest to be absorbed through skin.

Identification of Compound Heterozygous CYP11A1 Variants via Reanalysis of Clinical Sequencing Data

American Journal of Medical Genetics Part A, Volume 200, Issue 4, Page 923-928, April 2026.
ABSTRACT A molecular diagnosis is currently achievable in approximately 50% of patients assessed by clinical geneticists at tertiary care centres. Next‐Generation Sequencing Panels contain a defined group of genes associated with a clinically defined set of phenotypes.

Hypoxia drives spermatogenic impairment by triggering lysosome-dependent death of Leydig cells via M1 macrophage polarization

陆军军医大学学报
Objective To investigate the critical role of hypoxia in impairing spermatogenesis via M1 macrophage polarization and subsequent induction of lysosome-dependent cell death (LDCD) in Leydig cells. Methods Ten eight-week-old male SD rats (weight 220~250

IL1R2 Marks and Sorts a Spermatogonial Stem Cell Population Critical for Restoring Spermatogenesis Upon Interruption in Mammals

Advanced Science, Volume 13, Issue 13, 3 March 2026.
Spermatogonial stem cells (SSCs) provide critical support to spermatogenesis. Here, the author established Il1r2 as a sorting marker for SSCs, with which further insights into the SSC heterogeneity and dynamic features can be obtained. They also confirmed findings in both mouse and human, thus validating IL1R2 as the surface marker for isolating and ...

Targeting the CMKLR1‐Mediated Signaling Rebalances Immunometabolism State in Middle‐Age Testicular Macrophages

Advanced Science, Volume 13, Issue 14, 9 March 2026.
In middle age, testicular CMKLR1⁺ macrophages exhibited a pro‐inflammatory immunometabolic profile, mediated by adipose signals associated with high BMI. However, inhibition of CMKLR1 signaling, either through Cmklr1 genetic ablation or treatment with a CMKLR1 antagonist peptide, can reverse this phenotype.

[Leydig cell hypoplasia].

Arquivos brasileiros de endocrinologia e metabologia, 2006
The Leydig cell hypoplasia is a rare and well defined form of male pseudohermaphroditism with autosomal recessive inheritance pattern. An inadequate fetal testicular Leydig cell differentiation and, consequently a low androgenic production during intra uterine and post natal periods, result in absence or incomplete virilization in patients with 46,XY ...
