Ferroptosis in Obstetrical and Gynecological Diseases: A Mini Review.

Ferroptosis is an iron-dependent form of non-apoptotic cell programmed death, characterized by the disturbance of iron metabolism, accumulation of lipid peroxides and disruption of cellular antioxidant system. Ferroptosis induces oxidative cell death through decrease of antioxidant capacity and accumulation of lipid reactive oxygen species (ROS) in cells. In recent years, studies have confirmed that ferroptosis is closely related to numerous organ injuries, degenerative pathologies and even the tumorigenesis and therapeutic resistance of tumors.

Interaction of Exosomal MicroRNA and Oxidative Stress in the Pathogenesis of Colitis-Associated Cancer.

Colitis-associated cancer (CAC) is the most serious complication of inflammatory bowel disease. In recent years, the incidence of CAC has increased worldwide. Oxidative stress (OS) is involved in the development of CAC through oxidative damage to biomolecules or activation of inflammatory signaling pathways.

Single-cell RNA-seq Reveals the Inhibitory Effect of Methamphetamine on Liver Immunity with the Involvement of Dopamine Receptor D1.

Methamphetamine (METH) is a highly addictive psychostimulant that causes physical and psychological damage and immune system disorder, especially in the liver which contains a significant number of immune cells. Dopamine, a key neurotransmitter in METH addiction and immune regulation, plays a crucial role in this process. Here, we developed a chronic METH administration model and conducted single-cell RNA sequencing (scRNA-seq) to investigate the effect of METH on liver immune cells and the involvement of dopamine receptor D1 (DRD1).

Kupffer cells dictate hepatic responses to the atherogenic dyslipidemic insult.

Apolipoprotein-B (APOB)-containing lipoproteins cause atherosclerosis. Whether the vasculature is the initially responding site or if atherogenic dyslipidemia affects other organs simultaneously is unknown. Here we show that the liver responds to a dyslipidemic insult based on inducible models of familial hypercholesterolemia and APOB tracing.

Integrated pan-cancer analysis and experimental verification of the roles of meiotic nuclear divisions 1 in breast cancer.

Introduction: The aberrant up-regulation of meiotic nuclear division 1 (MND1) in somatic cells is considered as one of the driving factors of oncogenesis, whereas its expression and role in breast invasive cancer (BRCA) remain unclear. Hence, this study embarked on a comprehensive evaluation of MND1 across various cancers and identified its roles in BRCA.

Methods: Based on publicly available databases, including but not limited to UCSC Xena, TCGA, GTEx, GEO, STRING, GeneMANIA, and CancerSEA, we evaluated the expression patterns, genomic features, and biological functions of MND1 from a pan-cancer viewpoint and delved into the implications of MND1 in the prognosis and treatment of BRCA.

Red nucleus mGluR2 but not mGluR3 mediates inhibitory effect in the development of SNI-induced neuropathological pain by suppressing the expressions of TNF-α and IL-1β.

Our previous study has verified that activation of group Ⅰ metabotropic glutamate receptors (mGluRⅠ) in the red nucleus (RN) facilitate the development of neuropathological pain. Here, we further discussed the functions and possible molecular mechanisms of red nucleus mGluR Ⅱ (mGluR2 and mGluR3) in the development of neuropathological pain induced by spared nerve injury (SNI). Our results showed that mGluR2 and mGluR3 both were constitutively expressed in the RN of normal rats.
