Objective: To investigate the effect of small interference RNA (siRNA) targeting nuclear factor-kappaB (NF-kappaB) on endometriosis.
Method: The eutopic endometrium of women with endometriosis were transplanted into the nonvascular region of 8-day-old chicken embryo chorioallantocic membrane (CAM), and the effects of NF-kappaB p65 siRNA on the vascularization and endometriotic lesion formation were tested with proper controls.
Results: Transplantation of the endometrium onto the CAM resulted in a strong angiogenic response in the chicken tissue. The angiogenesis was significantly reduced and endometriotic lesion formation significantly suppressed with siRNA targeting NF-kappaB in comparison with the control group.
Conclusions: The NF-kappaB pathway is involved in the development of endometriotic lesions in vitro, and NF-kappaB gene silencing reduces endometriotic angiogenesis and promotes cell apoptosis in the endometriotic lesions, suggesting that NF-kappaB might be a good target for endometriosis treatment.

Background: Bacterial pathogens frequently encounter host-derived metabolites during their colonization and invasion processes, which can serve as nutrients, antimicrobial agents, or signaling molecules for the pathogens. The essential nutrient choline (Cho) is widely known to be utilized by a diverse range of bacteria and may undergo conversion into the disease-associated metabolite trimethylamine (TMA). However, the impact of choline metabolism on bacterial physiology and virulence remains largely unexplored.

Plant viruses have evolved different viral suppressors of RNA silencing (VSRs) to counteract RNA silencing which is a small RNA-mediated sequence-specific RNA degradation mechanism. Previous studies have already shown that the coat protein (CP) of cucumber mosaic virus (CMV) reduced RNA silencing suppression (RSS) activity of the VSR of CMV, the 2b protein. To demonstrate the universality of this CP-VSR interference, our study included three different viruses: CMV and peanut stunt virus (PSV) from the Bromoviridae, and plum pox virus (PPV) from the Potyviridae family.

Triple-negative breast cancer (TNBC) has been a clinical challenge due to its high recurrence and metastasis rates. Chemotherapy remains the primary treatment for TNBC after surgery ablation, but it lacks targeted specificity and causes side effects in normal tissues. Receptor tyrosine kinase-like orphan receptor 1 (ROR1) is significantly expressed in TNBC cells, and small interference RNA (siRNA) targeting ROR1 can effectively suppress ROR1 gene expression, thereby inhibiting proliferation and metastasis.

RNA silencing is a core cellular process that acts to defend the genome against potentially damaging genetic elements such as viruses and transposons. It has been extensively characterized in many eukaryotes and exploited as a tool for determining gene function through removing the activity of specific genes. It has also been used in Phytophthora species to reveal genes involved in different lifecycle stages.

Paroxetine, a selective serotonin reuptake inhibitor, is widely used in the clinical treatment of depression. While several antidepressants show promise as geroprotectors, the role of paroxetine in aging remains unclear. In this study, we evaluated the lifespan extension effect of paroxetine in Caenorhabditis elegans (C.
