Inflammatory cytokines and oral cancer risk: an integrated study combining two-sample Mendelian randomization with experimental validation.

Objective: This study aimed to investigate the causal relationship between inflammatory cytokines and oral cavity cancer risk using Mendelian randomization analysis and experimental validation.

Methods: Two-sample Mendelian randomization was conducted using summary-level genome-wide association study data on 41 inflammatory cytokines and oral cavity cancer risk in Europeans. Single nucleotide polymorphisms associated with cytokines (p < 5 × 10-6) and oral cancer were selected as instrumental variables, excluding those in linkage disequilibrium.

Exosomes derived from mesenchymal stem cells overexpressing miR-210 inhibits neuronal inflammation and contribute to neurite outgrowth through modulating microglia polarization.

Inflammatory responses play a critical role in the progress of neurodegenerative disorders. MSC-Exos is considered to have an anti-inflammatory effect on the treatment strategy for brain injury. However, the therapeutic effect and possible mechanism of Exosomal miR-210 on microglia polarization-induced neuroinflammation and neurite outgrowth have not been reported.

Engineered BMSCs-Derived Exosomal miR-542-3p Promotes Cutaneous Wound Healing.

Background: The healing of cutaneous wounds requires better strategies, which remain a challenge. Previous reports indicated that the therapeutic function of mesenchymal stem cells is mediated by exosomes. This work demonstrated the regenerative effects of engineered BMSCsderived Exosomal miR-542-3p in skin wound mouse models.

Leptin improves intestinal flora dysfunction in mice with high-fat diet-induced obesity.

Objective: This study investigated the effects of leptin on intestinal flora and inflammation in mice with high-fat diet (HFD)-induced obesity.

Methods: Mice were fed an HFD for 8 weeks; some were concurrently administered oral leptin for 4 weeks. Pathological changes in adipose tissue were detected using hematoxylin-eosin staining; endotoxin content in adipose tissue was measured by enzyme-linked immunosorbent assay.

OB-RGRP regulates the phosphorylation of JAK2 and STAT3 in primary rat adipocytes.

This study aimed to explore the role of obestatin R gene-related protein (OB-RGRP) in autocrine signal transduction of adipocytes. Primary rat adipocytes were isolated and verified by microscopic observation and oil red O staining. OB-RGRP expression vector and OB-RGRP siRNA (si-OB-RGRP) were constructed and transfected into adipocytes.
