Acromegaly: pathogenesis & treatment [PDF]

open access: yes, 2019
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]

open access: yes, 2019
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 ...

Adenylyl Cyclase 8 in Dorsal CA1 Neurons Prevents Depressive‐Like Behaviors by Maintaining Neuronal Excitability and Glutamatergic Neurotransmission Through TIP39‐PTH2R Signaling

open access: yesAdvanced Science, EarlyView.
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]

open access: yesPLoS ONE, 2011
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

open access: yesAdvanced Science, EarlyView.
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

open access: yesКреативная хирургия и онкология, 2020
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]

open access: yes, 2015
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.

PFOS Disrupts Oocyte Maturation and Early Embryonic Development via Ovarian FOXK1 O‐GlcNAcylation in Mice

open access: yesAdvanced Science, EarlyView.
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.

Characterization and Expression of Turkey Prolactin Regulatory Element Binding in the Anterior Pituitary Gland and Pancreas During Embryogenesis

open access: yesThe Journal of Poultry Science, 2016
The PRL regulatory element-binding (PREB) protein is a transcription factor that was originally cloned from the rat anterior pituitary gland and characterized as a regulator of the PRL promoter.

An expression and function analysis of the CXCR4/SDF-1 signalling axis during pituitary gland development.

open access: yesPLoS ONE, 2023
The chemokine SDF-1 (CXCL12) and its receptor CXCR4 control several processes during embryonic development such as the regulation of stem cell proliferation, differentiation, and migration.
