Objective: Quercetin is a flavonoid compound extracted from fruits and plants and is used as a natural antioxidant to prevent or treat a variety of diseases such as cancer, obesity, chronic inflammation, and reproductive system dysfunction. The aim of this study was to investigate the effects of quercetin on obesity and ovarian tissue by analyzing the expression of genes involved in the hypothalamus-pituitary-gonadal axis, including ob-Rb, ob-Ra, and brain-derived neurotrophic factor (Bdnf), neuropeptide Y (NPY), and Kisspeptin (Kiss-1).
Methods: In this experimental study, female rats were divided into three groups, and the effect of quercetin with doses of 50 and 100 mg/kg on weight and BMI was investigated. Also, the gene expression was assessed using the real-time PCR technique. The estrogen, progesterone, FSH, and LH were assessed using the chemiluminescence technique. The diameter and number of different types of follicles, corpus luteum, and blood vessels in mice were investigated. The growth indicators of the children, including the number, weight, and height and head width of the born children, were checked.
Results: Quercetin caused a decrease in BMI, a significant increase in the expression of ob-Rb, ob-Ra, and Bdnf genes, a significant decrease in the expression of NPY and Kiss-1 genes, and led to an increase in sex hormones. Quercetin improved follicular indices and increased the number of mouse embryos.
Conclusions: Probably, quercetin affects the hypothalamus-pituitary-gonadal axis by changing the expression of genes, and it helps to reduce obesity and increase fertility and better function of the reproductive system.

Importance: VEXAS syndrome (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) is a monogenic disease caused by UBA1 somatic variants in hematopoietic progenitor cells, mostly involving adult men. It is associated with inflammatory-related symptoms, frequently involving the skin and hematological disorders. Recently described myelodysplasia cutis (MDS-cutis) is a cutaneous manifestation of myelodysplasia in which clonal myelodysplastic cells infiltrate the skin.

Purpose: After stromal injury to the cornea, the release of growth factors and pro-inflammatory cytokines promotes the activation of quiescent keratocytes into a migratory fibroblast and/or fibrotic myofibroblast phenotype. Persistence of the myofibroblast phenotype can lead to corneal fibrosis and scarring, which are leading causes of blindness worldwide. This study aims to establish comprehensive transcriptional profiles for cultured corneal keratocytes, fibroblasts, and myofibroblasts to gain insights into the mechanisms through which these phenotypic changes occur.

Tissue-resident macrophages adopt distinct gene expression profiles and exhibit functional specialization based on their tissue of residence. Recent studies have begun to define the signals and transcription factors that induce these identities. Here we describe an unexpected and specific role for the broadly expressed transcription factor Krüppel-like factor 2 (KLF2) in the development of embryonically derived large cavity macrophages (LCMs) in the serous cavities.

A previously reported clinical trial in familial adenomatous polyposis (FAP) patients treated with erlotinib plus sulindac (ERL + SUL) highlighted immune response/interferon-γ signaling as a key pathway. In this study, we combine intermittent low-dose ERL ± SUL treatment in the polyposis in rat colon (Pirc) model with mechanistic studies on tumor-associated immune modulation. At clinically relevant doses, short-term (16 weeks) and long-term (46 weeks) ERL ± SUL administration results in near-complete tumor suppression in Pirc colon and duodenum (p < 0.
