Ex Vivo Spatiotemporal Characterization of Spermatogenesis in Mouse Testicular Organoids

Advanced 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.

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

Advanced 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.

Expression of three GnRH receptors in specific tissues in male and female sea lampreys Petromyzon marinus at three distinct life stages [PDF]

, 2013
Two recently cloned gonadotropin-releasing hormone (GnRH) receptors (lamprey GnRH-R-2 and lamprey GnRH-R-3) along with lamprey (l) GnRH-R-1 were shown to share similar structural features and amino acid motifs common to other vertebrate receptors.

The Pivotal Role of GR‐CAR Pathway in Fetal Programming of Hepatic Cytochrome P450 3A Alteration in Adulthood

Advanced Science, EarlyView.
Prenatal dexamethasone exposure (PDE) persistently upregulates hepatic CYP3A1/CYP2B1 in offspring via glucocorticoid receptor (GR) activation. In vivo and in vitro studies show GR promotes P300/CBP binding to the constitutive androstane receptor (CAR) promoter, sustaining histone acetylation (H3K9/K27ac) and enhancing CYP expression. The GR–CAR pathway

Magnetic resonance imaging (MRI) findings in isolated growth hormone deficiency

The Turkish Journal of Pediatrics, 1998
In this study the presence of pituitary-hypothalamic abnormalities was searched by magnetic resonance (MR) imaging in 30 children (18 males and 12 females, aged 7.4 to 23 years) with isolated growth hormone deficiency (IGHD).

Methotrexate-associated lymphoproliferative disorder with hypopituitarism and central diabetes insipidus

Endocrinology, Diabetes & Metabolism Case Reports, 2019
Patients treated with immunosuppressive drugs, especially methotrexate (MTX), rarely develop lymphoproliferative disorders (LPDs), known as MTX-related LPD (MTX–LPD). The primary site of MTX–LPD is often extranodal. This is the first reported case of MTX–

Migrasomes in Ischemic Stroke: Molecular Landscape and Pathophysiological Impact

Advanced Science, EarlyView.
Multi‐omics profiling of stroke patients exposes systemic molecular fingerprints of immune activation, oxidative stress and metabolic collapse. Complement and coagulation cascade, and cholesterol metabolism emerge as shared functional hallmarks of plasma migrasomes in stroke patients and migrasomes isolated from experimental stroke mice.

Excitatory and inhibitory effects of prolactin release activated by nerve stimulation in rat anterior pituitary

Reproductive Biology and Endocrinology, 2009
Background A series of studies showed the presence of substantial amount of nerve fibers and their close relationship with the anterior pituitary gland cells. Our previous studies have suggested that aside from the classical theory of humoral regulation,

The anterior pituitary and reproduction in bats [PDF]

Reproduction, 1979
This contribution is a review of investigations on the role(s) of the anterior pituitary in chiropteran reproduction. Information on this subject has come mainly from histological studies of cytological changes during the annual cycle and mostly from hibernating temperate-zone species. Although direct evidence is unavailable, it appears that variations

Unexpectedly High Incidence of Immune‐Related Adverse Events in Gastric Cancer Patients Who Received Conversion Surgery After Nivolumab‐Including Chemotherapy

Annals of Gastroenterological Surgery, EarlyView.
ABSTRACT Background Nivolumab‐including chemotherapy (nivo‐CTX) for stage IV gastric cancer (GC) may increase the chance of conversion surgery but risk of immune‐related adverse events (irAEs) during perioperative period remains unclear. Methods We examined irAEs in 36 patients with marginally resectable GC who received nivo‐CTX followed by surgery ...
