Potential hazard assessment of 6PPD-quinone in the context of ulcerative colitis: network toxicology, machine learning, transcriptomic analysis, and preliminary In vivo validation

BackgroundThe ubiquitous tire-derived pollutant 6PPD-quinone (6PPD-Q) poses potential systemic health risks, yet its toxicological impact on the intestinal tract, particularly in the context of ulcerative colitis (UC), remains largely unknown. This stu…

Treatment sequence of stem cell delivered heterologous oncolytic virus impact on tumor microenvironment in immunocompetent ovarian cancer model

IntroductionOvarian cancer (OC) is a biologically heterogeneous malignancy associated with poor clinical outcomes. Oncolytic viruses (OVs) have emerged as a promising immunotherapeutic strategy; however, optimal approaches to maximize their antitumor e…
