As shown in Fig. 2C, TMCC1 protein was detected in all cell lines examined, with epithelial cells (Hep G2, Caco-2, and A549), neuroblastoma cells (SH-SY5Y), and glioblastoma cells (U87) showing high expression levels of TMCC1, and leukemia cells (HL-60 and HEL) and lymphoma cells (U-937) showing low expression levels. Here, TMCC1 is linked to glioblastoma.
