Acromegaly: pathogenesis & treatment [PDF]
Acromegaly is a multi-system disorder whose etiology is most often traced back to a growth hormone-secreting pituitary adenoma (PA). Growth hormone (GH) secretion promotes insulin-like growth factor 1 (IGF-1) release from peripheral tissues, leading to ...

Soluble guanylyl cyclase α1 subunit is a key mediator of proliferation, survival, and migration in ECC-1 and HeLa cell lines [PDF]
Soluble guanylyl cyclase (sGC) is a heterodimeric enzyme constituted by two subunits, α1 and β1. Previously we have shown that 17β-estradiol (E2) exerts opposite effects on these subunits by increasing α1 and decreasing both β1 expression and enzymatic ...

Depression, a prevalent neuropsychiatric disorder with unclear pathogenesis, involves dysfunctional adenylyl cyclase 8 (Adcy8) as a key risk factor. Chronic stress selectively reduces Adcy8 expression in the dorsal CA1 (dCA1) neurons. Depletion of Adcy8 in dCA1 excitatory neurons induces depressive‐like behaviors by impairing neuronal excitability and ...

Nitric oxide-sensitive guanylyl cyclase is differentially regulated by nuclear and non-nuclear estrogen pathways in anterior pituitary gland. [PDF]
17β-estradiol (E2) regulates hormonal release as well as proliferation and cell death in the pituitary. The main nitric oxide receptor, nitric oxide sensitive- or soluble guanylyl cyclase (sGC), is a heterodimer composed of two subunits, α and β, that ...

Ex Vivo Spatiotemporal Characterization of Spermatogenesis in Mouse Testicular Organoids
To date, in vitro spermatogenesis remains a challenge in reproductive medicine. In this study, Sun et al. developed a promising in vitro strategy to generate testicular organoids that enable germ cells from newborn mice to enter meiosis, complete chromosome recombination and synapsis, and develop into haploid spermatids.

Diagnosis and Treatment of Pituitary Adenomas
Pituitary adenomas are among the most common primary intracranial tumours. They are predominantly benign and account for 10–15 % of all intracranial neoplasms. These tumours are divided into two subgroups: macroadenomas (> 1 cm) and microadenomas (<

The development of the skull of the Egyptian cobra Naja h. haje (Squamata: Serpentes: Elapidae) [PDF]
Background: The study of craniofacial development is important in understanding the ontogenetic processes behind morphological diversity. A complete morphological description of the embryonic skull development of the Egyptian cobra, Naja h.

Perfluorooctane sulfonate (PFOS) exposure disrupts oocyte maturation and early embryonic development. This study elucidates the mechanism by which enhanced O‐GlcNAcylation of FOXK1 underlies the PFOS‐induced reduction of progesterone levels in granulosa cells and the disturbance of follicular microenvironment.
