Abstract Background: Circular RNAs play an important role in regulating lung adenocarcinoma (LUAD). Bioinformatics analysis identified circ_0015278 as differentially expressed in LUAD. However, the biological mechanism of circ_0015278 in LUAD has not been fully clarified, especially in ferroptosis. Materials and Methods: Bioinformatics analysis was employed to explore the downstream mechanisms of Circ_0015278, subsequently confirmed by luciferase reporter assays. The impact of Circ_0015278 on cell proliferation, migration, invasion, and ferroptosis was investigated through a loss-of-function experiment. A xenotransplantation mouse model elucidated the effect of Circ_0015278 on tumour growth. Results: Circ_0015278 exhibited downregulation in LUAD. It inhibited cell proliferation, More >

Abstract Osteosarcoma is a very serious primary bone cancer with a high death rate and a dismal prognosis. Since there is no permanent therapy for this condition, it is necessary to develop a cure. Therefore, this investigation was carried out to assess the impacts and biological functions of hydroxysafflor yellow A (HYSA) in osteosarcoma cell lines (MG63). In this investigational study, MG63 cells were utilized. Microarray experiments, quantitative polymerase chain reaction (qPCR), immunofluorescent staining, extracellular acidification rate (ECAR), oxygen consumption rate (OCR), glucose consumption, lactate production, and ATP levels, proliferation assay, 5-Ethynyl-2′-deoxyuridine (EDU) staining, and Western… More >

Abstract Background: Inflammatory bowel disease (IBD) is a chronic inflammatory disease of the gastrointestinal tract. The destruction of the intestinal epithelial barrier is one of the major pathological processes in IBD pathology. Growing evidence indicated that epithelial cell ferroptosis is linked to IBD and is considered a target process. Methods: RAS-selective lethal 3 (RSL3) was used to induce ferroptosis in intestinal epithelial cell line No. 6 (IEC-6) cells, and cell ferroptosis and the effects of tanshinone IIA (Tan IIA) were determined by cell counting kit-8 (CCK-8), reactive oxygen species (ROS) staining, Giemsa staining and transmission electron microscope… More >
