The Neuroendocrine Impact of Acute Stress on Synaptic Plasticity
We describe the synaptic plasticity that occurs in four stress-associated brain structures, the hypothalamus, hippocampus, amygdala, and prefrontal cortex, in response to single or short-term stress exposure. The rapid transformative impact of glucocorticoids makes this stress signal a particularly potent effector of acute neuronal plasticity.PMID:37788632 | DOI:10.1210/endocr/bqad149 (Source: Endocrinology)

Lesions of KNDy and Kiss1R neurons in the arcuate nucleus produce different effects on LH pulse patterns in female sheep
This study tested the functional role of ovine KNDy neurons in pulse generation and explored the roles of nearby Kiss1 receptor (Kiss1R)-containing cells using lesions produced with saporin (SAP) conjugates. Injection of NK3-SAP ablated over 90% of the KNDy cells, while Kiss-SAP (saporin conjugated to kisspeptin-54) lesioned about two-thirds of the Kiss1R population without affecting KNDy or GnRH cell number. Both lesions produced a dramatic decrease in LH pulse amplitude, but had different effects on LH pulse patterns. NK3-SAP increased interpulse interval (IPI), but Kiss-SAP did not. In contrast, Kiss-SAP disrupted the r...

Legacy and emerging per- and polyfluoroalkyl substances (PFAS) regulate steroidogenesis in the male gonad
Endocrinology. 2023 Sep 28:bqad142. doi: 10.1210/endocr/bqad142. Online ahead of print.ABSTRACTPer- and polyfluoroalkyl substances (PFAS) are widely used in a variety of industrial processes and manufacturing of consumer products. Current efforts by the manufacturing industry will limit use of long-chain or legacy PFAS represented by perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) and replace with short-chain or emerging PFAS such as perfluorobutanoic acid (PFBA) and perfluorobutane sulfonic acid (PFBS). However, there is little to no information on the toxicity of new and emerging PFAS. Therefore, w...

Functional Water Channels Within the TSH Receptor - a new paradigm for TSH action with disease implications
Endocrinology. 2023 Sep 28:bqad146. doi: 10.1210/endocr/bqad146. Online ahead of print.ABSTRACTThe TSH receptor (TSHR) transmembrane domain (TMD) lives in the plasma membrane consisting of lipids and water molecules. To understand the role of TSHR-associated water molecules we used molecular dynamic simulations of the TMD and identified a network of putative receptor associated transmembrane water channels. This result was confirmed with extended simulations of the full length TSHR with and without TSH ligand binding. While the transport time observed in the simulations via the TSHR protein was slower than via the lipid bi...

Puberty suppression followed by testosterone therapy does not impair reproductive potential in female mice
This study used a translational murine IVF model to examine the effects of female puberty suppression with depot leuprolide acetate (LA), followed by virilizing therapy with testosterone cypionate (T), on embryologic and pregnancy outcomes. LA effectively inhibited puberty when mice were treated beginning at 3 weeks of age. LA treatment was associated with higher mouse weight but lower ovarian weight. LA-treated mice ovulated developmentally competent eggs in response to gonadotropin administration, albeit at a higher dose than controls. Ovaries from mice treated with LA and T produced oocytes that had morphologically norm...

Research Progress of Metformin in the Treatment of Oral Squamous Cell Carcinoma
Endocrinology. 2023 Sep 20:bqad139. doi: 10.1210/endocr/bqad139. Online ahead of print.ABSTRACTOral squamous cell carcinoma (OSCC) is one of the most common malignancies with high mortality, posing a great threat to both human physical and mental health. With the advancement of scientific research, a variety of cancer therapies have been used for OSCC treatment. However, the prognosis of OSCC shows no significant improvement. Metformin has been recognized as the first-line drug for the treatment of diabetes, and recent studies have shown that metformin has a remarkable suppressive effect on tumor progression. Metformin can...
