Abnormality of granulosa cells (GCs) is the critical cause of follicular atresia in premature ovarian failure (POF). RIPK3 is highly expressed in GCs derived from atretic follicles. We focus on uncovering how RIPK3 contributes to ovarian GC senescence.

Background: Achieving a stable vasculature is crucial for tissue regeneration. Endothelial cells initiate vascular morphogenesis, followed by mural cells that stabilize new vessels. This study investigated the in vivo effects of Sema4D-Plexin-B1 signaling on stem cells from human exfoliated deciduous teeth (SHED)-supported angiogenesis, focusing on its mechanism in PDGF-BB secretion.

Novel kappa opioid receptor (KOR) agonists that preferentially activate G-protein signaling versus β-arrestin-2 recruitment are described. Starting from a literature-reported phenol-containing diphenethylamine KOR agonist, structure-activity relationship (SAR) studies revealed replacement of the phenol with various non-hydroxylated bicyclic heteroaromatics led to tertiary diarylethylamines which retained KOR agonist activity and improved metabolic stability in human liver microsomes. Further optimizations produced compound 39, a potent activator of G-protein signaling (GTPγS EC = 14 nM, 83 % E) that did not elicit a β-arrestin-2 recruitment functional response (E < 10 %).

CRC (Colorectal cancer) ranks among the most prevalent tumors in humans and remains a leading cause of cancer-related mortality worldwide. Numerous studies have highlighted the connection between inflammasome over-activation and the initiation and progression of CRC. The activation of the NLRP3 (NOD-like receptor family, pyrin domain containing 3) inflammasome is dependent on the nuclear NF-kβ (Nuclear Factor kappa-light-chain-enhancer of activated B cells) pathway, leading to the maturation and release of inflammatory cytokines such as IL-1ß (Interleukin 1 beta) and IL-18 (Interleukin 18).

Neovascular age-related macular degeneration and diabetic macular edema are leading causes of vision-loss evoked by retinal neovascularization and vascular leakage. The glycoprotein microfibrillar-associated protein 4 (MFAP4) is an integrin αβ ligand present in the extracellular matrix. Single-cell transcriptomics reveal MFAP4 expression in cell-types in close proximity to vascular endothelial cells including choroidal vascular mural cells and retinal astrocytes and Müller cells.
