Abstract Introduction Ankylosing spondylitis (AS) is a chronic autoimmune disease, and the precise pathogenesis largely unknown at present. Bone marrow-derived mesenchymal stem cells (BMSCs) with immunosuppressive anti-inflammatory potential Th17/Treg reciprocal relationship regulated by BMSCs have been reported to be involved in some disorders. Here we studied biological immunological characteristics of BMSCs, frequency phenotype CCR4 + CCR6 Th/Treg their interaction vitro AS. Methods The...

The control of self-renewal and differentiation neural stem progenitor cells is a crucial issue in cell cancer biology. Drosophila type II neuroblast lineages are prone to developing impaired homeostasis if the limited self-renewing potential intermediate progenitors (INPs) unrestrained. Here, we demonstrate that SWI/SNF chromatin remodeling Brahma (Brm) complex functions cooperatively with another factor, Histone deacetylase 3 (HDAC3) suppress formation ectopic neuroblasts. We show multiple...

Although many staging classifications have been proposed for hepatocellular carcinoma (HCC), determining a patient's prognosis in clinical practice is challenge due to the molecular diversity of HCC. We investigated relationship between MEP1A, candidate oncogene, and outcomes HCC patients; furthermore, we explored role MEP1A In this report, it was demonstrated by quantitative real‐time polymerase chain reaction that messenger RNA levels were significantly elevated tumor tissues compared with...

Non-small cell lung cancer (NSCLC) stands prominent among the prevailing and formidable oncological entities. The immune metabolic-related molecule Phospholipase A2, group IID (PLA2G2D) exerts promotional effects on tumor progression. However, its involvement in angiogenesis remains elusive. Therefore, this investigation delved into functional significance of PLA2G2D concerning NSCLC. This study analyzed expression enriched pathways NSCLC tissues through bioinformatics analysis, measured...
