However, its impact on angiogenesis modulation, particularly through the synaptopodin-2-like (SCEL) gene, remains poorly understood. The effects of BSP on HMEC-1 cells exposed to lipopolysaccharide (LPS) were assessed using cell viability, migration, apoptosis, and angiogenesis assays. SCEL's role was explored through lentiviral transfection to manipulate SCEL expression. Animal models were employed to evaluate BSP's therapeutic potential in burn wound healing, with histological analysis, immunohistochemistry (IHC), and molecular assays to assess tissue repair and angiogenesis. BSP significantly alleviated LPS-induced damage in HMEC-1 cells by promoting cell survival, reducing apoptosis, and enhancing migration and angiogenesis. BSP treatment downregulated SCEL expression, reversing LPS-induced cellular damage. In SCEL-overexpressing cells and mice, BSP's beneficial effects on wound healing were attenuated, indicating SCEL's regulatory role in angiogenesis. In vivo, BSP accelerated burn wound closure, improved tissue organization, and enhanced angiogenesis, as evidenced by increased CD31 expression. SCEL overexpression impaired these effects, highlighting the essential role of SCEL downregulation in BSP-mediated healing.

The present study investigated how TGF-β1 induces ferroptosis and thereby contributes to renal tubular epithelial cell fibrosis. Bioinformatics was employed to identify the differentially expressed genes relevant to renal fibrosis. An in vitro TGF-β1-induced fibrosis model of HK-2 cells was established, and the cell shape index was calculated. Fer-1, NAC, and PD98059 were utilized for targeted intervention, and their mechanisms were verified by transducing cells with WISP1-targeting shRNA lentivirus. Cell morphology was examined under a microscope, and cells were collected to determine the levels of ferroptosis-related factors (Fe<sup>2+</sup>, MDA, GSH, and LPO). Western blotting was performed to measure the levels of ERK1/2, WISP1, and ferroptosis indicators (GPX4 and hyperoxidized PRDX4). Flow cytometry was performed to determine the ROS levels and the rate of cell ferroptosis. TGF-β1 induced the transformation of HK-2 cells into fibroblast-like cells, leading to increased ROS levels, activation of the ERK1/2-WISP1 signaling pathway, and upregulation of ferroptosis and fibrosis-related factors. However, these effects could be effectively inhibited through pretreatment with Fer-1, NAC, and PD98059 individually, which further validated the involvement of the ERK1/2-WISP1 signaling pathway. In addition, WISP1 knockdown suppressed the cell transformation into fibroblast-like cells as well as the ferroptosis process, thereby reducing the expression levels of ferroptosis and fibrosis-related factors.
