Article Title: RNA methyltransferase NSUN2 enhances vasculogenic mimicry and malignant progression of cervical cancer through upregulation of MMP-9

doi: 10.3892/ol.2026.15518

Figure Lengend Snippet: MMP-9 , a factor that promotes Vasculogenic mimicry, is highly expressed in CC and is associated with poor prognosis. (A) CC database of TCGA was used to analyze key factors associated with VM. (B) Association of Sox2 expression with overall survival in CC (log-rank test). (C) Association of MMP-9 expression with overall survival in CC (log-rank test). (D) Panoramic scans after immunohistochemical detection of MMP-9 and H&E staining in samples from cancerous and paracancerous tissues from subjects with CC. Scale bar, 50 µm. Original magnification, ×20. (E) Protein levels of MMP-9 in 20 paired samples, with the MMP-9 level in CC tissue expressed compared with that in the paired normal tissue. (F) Expression levels of MMP-9 mRNA in 44 paired CC and paracancerous tissues, with MMP-9 expression in CC tissue expressed compared with that in the paired normal tissue. (G) Comparison of the average expression levels of MMP-9 mRNA in CC tissues compared with paracancerous tissues. (H) HeLa and SiHa cells were incubated under hypoxia (0.1% O 2 ) and proteins collected at 24, 48 and 72 h for western blotting of ALDH1, EPHA2, MMP-9 and GAPDH. ImageJ was used to semi-quantify western blotting signals from HeLa (I) and SiHa (J) cells. GAPDH served as an internal reference. *P<0.05, **P<0.01 and ***P<0.001.
