Cysteine‑ and glycine‑rich protein 2 (CSRP2) are closely associated with tumor invasion and metastasis. CSRP2 is significantly upregulated in glioma tissues and is associated with the clinical stage of the tumor. Overexpression of CSRP2 in glioma cells promotes the proliferation and metastasis of cancer cells, whereas CSRP2 knockdown inhibits the biological functions of tumor cells. Transcriptome sequencing of CSRP2‑knockdown U251M cells revealed that silencing of CSRP2 inhibited the JAK‑STAT1 signaling pathway, and differentially expressed genes were significantly enriched in cell processes related to necroptosis. Experiments on necroptosis in glioma cells using flow cytometry, Hoechst 33342/PI dual staining and transmission electron microscopy indicated that CSRP2 overexpression inhibited necroptosis in glioma cells. Western blotting results showed that overexpression of CSRP2 activated the JAK‑STAT1 signaling pathway, while the addition of the pathway inhibitor ruxolitinib promoted the phosphorylation of necroptosis proteins RIPK1, RIPK3 and MLKL. Therefore, it was hypothesized that CSRP2 maintains JAK‑STAT1 activation by inhibiting the protein inhibitor of activated STAT1, which then inhibits the necrotizing apoptosis of glioma cells.
