The aims of this study were to investigate the localization of non-phosphorylated β‑catenin and Galectin-3 (GAL-3), the regulation of the expression of both proteins by activation of estrogen receptors (ERs) and their role in tumorigenic characteristics of androgen-independent prostate cancer DU-145 cells. DU-145 cells were cultured in the absence (control), and presence of 17β-estradiol (E2). Cells were also untreated or pre-treated with the inhibitor of GAL‑3, VA03, or with a compound that disrupts the complex β-catenin-TCF/LEF transcription factor, PKF 118-310.

Environmental endocrine disruptor chemicals (EDCs) have raised significant concerns due to their potential adverse effects on human health, particularly on the central nervous system (CNS). This study provides a comparative analysis of the effects of 17-alpha ethinyl estradiol (EE2) and diethyl phthalate (DEP) on neuronal cell proliferation and neurotoxicity. Using differentiated SH-SY5Y human neuronal cells, we evaluated cell viability, microRNA (miRNA) regulation, and RNA expression following exposure to subtoxic concentrations of EE2 and DEP.

Background: Tris (2-chloroethyl) phosphate (TCEP), a widely used flame retardant, is widespread in the environment and potentially harmful to organisms. However, the specific mechanisms of TCEP-induced neurological and reproductive toxicity in fish are largely unknown. Turbot (Scophthalmus maximus) is cultivated on a large scale, and the emergence of pollutants with endocrine disrupting effects seriously affects its economic benefits.

Context The adipose tissue produces adipokines - hormones essential to many biological functions, including reproduction. Aims We hypothesised that resistin, one of the adipokines, is present in the blood plasma, uterine luminal flushings (ULF) and uterus of pigs during the oestrous cycle and early pregnancy, and that resistin influences uterine steroidogenesis. Methods This study aimed to determine the expression of resistin in the porcine endometrium and myometrium during the cycle and pregnancy by quantitative real-time polymerase chain reaction and western blot (WB).

The aim of this study was to determine the effect of Sparstolonin B (SsnB) on cell proliferation and apoptosis in human breast cancer (MCF-7) and human ovarian epithelial cancer (OVCAR-3) cell lines in the presence and absence of estradiol hemihydrate (ES). Phosphoinositol-3 kinase (PI3K), phosphorylated protein kinase B alpha (p-AKT), phosphorylated mTOR (mechanistic target of rapamycin) signaling proteins, and sphingomyelin/ceramide metabolites were also measured within the scope of the study. The anti-proliferative effects of SsnB therapy were evaluated over a range of times and concentrations.
