Article Abstract

We previously observed that nonylphenol (NP) exposure during development resulted in increases in body weight and hyperadrenalism in adult male offspring. The mechanism of hyperadrenalism includes the primary activation of the adrenal gland and the conversion of inactive glucocorticoids to active glucocorticoids by 11β-HSD1. The inhibition of 11β-HSD1 is investigated as a new therapeutic approach. This study examined the effect of PF915275 (a selective 11β-HSD1 inhibitor) on hyperadrenalism and adipogenesis in male rats exposed to NP during development. The results showed that treatment with the 11β-HSD1 inhibitor PF915275 reversed/alleviated NP-induced hyperadrenalism via the following mechanisms: (1) decreasing serum corticosterone, 11β-hydroxylase, and aldosterone synthase levels; (2) significantly increasing PPARα protein and mRNA expression. In adipose tissue, NP significantly increased PPARγ mRNA expression, whereas PF915275 significantly decreased the level of mRNA expression; and (3) the expression of key regulators/enzymes in the adipogenesis metabolic pathway was also modulated.

FBXW7 is a tumor suppressor gene that regulates metabolism and is associated with the onset and progression of colorectal cancer (CRC)), however, the precise mechanism whereby FBXW7 participates in the metabolic reprogramming of CRC remains unclear. Here, the research aims to reveal the association between the expression of FBXW7 and clinical variables and to investigate the molecular mechanism by which FBXW7 plays a critical role in the development of CRC. The clinical importance of FBXW7 in CRC was determined by immunohistochemistry.

Enhancing protein O-GlcNAcylation by pharmacological inhibition of the enzyme O-GlcNAcase (OGA) has been considered as a strategy to decrease tau and amyloid-beta phosphorylation, aggregation, and pathology in Alzheimer's disease (AD). There is still more to be learned about the impact of enhancing global protein O-GlcNAcylation, which is important for understanding the potential of using OGA inhibition to treat neurodegenerative diseases. In this study, we investigated the acute effect of pharmacologically increasing O-GlcNAc levels, using the OGA inhibitor Thiamet G (TG), in normal mouse brains.

Postmenopausal osteoporosis (PMOP) is a chronic systemic bone metabolism disorder. Promotion in the patterns of human bone marrow mesenchymal stem cells (hBMSCs) differentiation towards osteoblasts contributes to alleviating osteoporosis. Aucubin, a natural compound isolated from the well-known herbal medicine Eucommia, was previously shown to possess various pharmacological effects.

The aim of present study was to evaluate the impact of perimenopause on insulin resistance. Specifically, insulin sensitivity was assessed in a perimenopausal mouse model treated with 4-vinylcyclohexene diepoxide (VCD), together with the changes in exosomal miRNA and hepatic mRNA expression profiles. Homeostasis model assessment of insulin resistance (HOMA-IR) was utilized to assess the status of insulin resistance, and insulin action was evaluated during menopausal transition.
