Article Abstract
Tribbles homolog 2 (TRIB2) is implicated in tumorigenesis and drug resistance in various types of cancers. However, the role of TRIB2 in the regulation of tumorigenesis and drug resistance of cancer stem cells (CSCs) is still elusive. In the present study, we showed increased expression of TRIB2 in spheroid-forming and aldehyde dehydrogenase-positive CSC populations of A2780 epithelial ovarian cancer cells. Short hairpin RNA-mediated silencing of TRIB2 expression attenuates the spheroid-forming, migratory, tumorigenic, and drug-resistant properties of A2780 cells, whereas overexpression of TRIB2 increases the CSC-like characteristics. TRIB2 overexpression induced GSK3β inactivation by augmenting AKT-dependent phosphorylation of GSK3β at Ser9, followed by increasing β-catenin level via reducing the GSK3β-mediated phosphorylation of β-catenin. Treatment of TRIB2-ovexpressed A2780 cells with the phosphoinositide-3-kinase inhibitor LY294002 abrogated TRIB2-stimulated proliferation, migration, drug resistance of A2780 cells. These results suggest a critical role for TRIB2 in the regulation of CSC-like properties by increasing the stability of β-catenin protein via the AKT-GSK3β-dependent pathways.

Resistance-conferring mutations in the androgen receptor (AR) ligand-binding pocket (LBP) compromise the effectiveness of clinically approved orthosteric AR antagonists. Targeting the dimerization interface pocket (DIP) of AR presents a promising therapeutic approach. In this study, we report the design and optimization of -(thiazol-2-yl) furanamide derivatives as novel AR DIP antagonists, among which was the most promising candidate.

Antimicrobial resistance (AMR) is a significant public health concern globally, and Pakistan is no exception. The misuse and overuse of antibiotics, inadequate regulation of their sale, and a lack of awareness contribute to the rising levels of AMR in the country. study presents a detailed analysis of blood and urine samples collected in Pakistan over various periods, focusing on pathogen prevalence, gender distribution, and age-wise patterns.

Crosstalk between leukemic cells and their surrounding mesenchymal stromal cells (MSCs) in the bone marrow microenvironment is crucial for the pathogenesis of myelodysplastic syndromes (MDS) and is mediated by extracellular vesicles (EVs). The EV-specific miRNAs derived from MDS-MSCs remain poorly explored. EVs isolated from HS-5, an immortalized stromal cell line, promoted the proliferation and 5-azacytidine (AZA) resistance of SKM-1 cells.

Antimicrobial resistance is largely driven by overuse of antibiotics, which is particularly common in low- and middle-income countries. We combine provider knowledge assessments and over 2000 anonymous standardized patient visits to providers in India to examine why they overprescribe antibiotics for pediatric diarrhea and figure out how to reduce overprescribing. Seventy percent of providers prescribed antibiotics without indication of bacterial infection.

IFN-β, a type I interferon, has been used as a first-line therapy for patients with multiple sclerosis (MS) for more than 30 years; however, the cellular and molecular basis of its therapeutic efficacy remains unclear. Here, we first used experimental autoimmune encephalomyelitis (EAE), a mouse model for MS, to show that the therapeutic effects of IFN-β were associated with a down-regulation of microRNA-21 (miR-21) and pathogenic T17 (pT17) cells. In vitro experiments demonstrated that genetic knockout of miR-21 directly inhibited pathogenic T17 cell differentiation.
