Figure 4. Verify the mutual regulation relationship between CHPF and MAD1L1. (A) The proteins potentially interacted with CHPF by IP and LC-MS/MS assays. (B) Gene ontology analysis of potentially interacted proteins with CHPF. (C) The result of IP and LC-MS/MS assays. (D) CHPF expression was positively associated with MAD1L1 expression in GBM based on GEPIA dataset. (E) Effects of CHPF knockdown on inhibiting MAD1L1 expression in U251 and U87 cells. (F) Co-IP assays were conducted to verify the interaction between CHPF and MAD1L1 in U251 and U87 cells. (G) The interaction between CHPF and MAD1L1 was verified using GST pull-down assay. (H) Immunofluorescence experiment revealed the location of CHPF and MAD1L1 in 251 cells.
