Novas perspectivas no diagnóstico do hipogonadismo pediátrico masculino: a importância do AMH como marcador de células de Sertoli [PDF]
Sertoli cells are the most active cell population in the testis during infancy and childhood. In these periods of life, hypogonadism can only be evidenced without stimulation tests, if Sertoli cell function is assessed.

The Semaphorin 3E (Sema3E)‐Plexin‐D1 pathway mediated by C/EBPα and C/EBPβ downstream of the luteinizing hormone (LH) surge plays important roles in the mouse preovulatory ovary. Timely activation and suppression of this pathway during the preovulatory stage are crucial for ovulation, corpus luteum formation, and proper angiogenesis.

LRRC4 deficiency disrupts the metabolic homeostasis of mitochondrial aerobic respiration and glycolysis during GC differentiation by inhibiting the ubiquitination‐mediated degradation of YAP, which ultimately leads to POI. These findings reveal the novel molecular etiology of POI and provide a promising target for prevention and treatment.

Duplicated membrane estrogen receptors in the European sea bass (Dicentrarchus labrax): Phylogeny, expression and regulation throughout the reproductive cycle [PDF]
The numerous estrogen functions reported across vertebrates have been classically explained by their binding to specific transcription factors, the nuclear estrogen receptors (ERs).

A Splice‐Region Variant Causes an Atypical Presentation of GNAS Inactivation Disorder
ABSTRACT Pathogenic variants in GNAS can cause a wide range of diseases including pseudohypoparathyroidism, pseudopseudohypoparathyroidism, McCune‐Albright syndrome, among others. The specific phenotypic features that may be seen are influenced by the variant type and location in the gene, whether it causes loss or gain of function, and whether it is ...

Deciphering the skeletal interoceptive circuitry to control bone homeostasis
This review introduces the skeletal interoceptive circuitry, covering the ascending signals from bone tissues to the brain (sensors), the central neural circuits that integrate this information and dispatch commands (CPU), and the descending pathways that regulate bone homeostasis (effectors).
