Title: PRSS contributes to cetuximab resistance in colorectal cancer Document date: 2020_1_1
ID: tymoeyoo_52
Snippet: The CRC cell lines were plated in six-well plates. After 24 hours, the cells were washed with PBS and cultured for 24 hours in serum-free medium. The cell supernatant and protein were collected for immunoblotting. We also detected the biochemical responses of cetuximabtreated cells by immunoblotting. During incubation in serum-free medium, the cells were treated with cetuximab for 24 hours. Cell extracts were freshly prepared and analyzed. Antibo.....
Document: The CRC cell lines were plated in six-well plates. After 24 hours, the cells were washed with PBS and cultured for 24 hours in serum-free medium. The cell supernatant and protein were collected for immunoblotting. We also detected the biochemical responses of cetuximabtreated cells by immunoblotting. During incubation in serum-free medium, the cells were treated with cetuximab for 24 hours. Cell extracts were freshly prepared and analyzed. Antibodies against EGFR, pAKT (Ser 473 ), AKT, p-p42/44 MAPK (Thr 202 /Tyr 204 ), p42/44 MAPK, and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) were purchased from Cell Signaling Technology. The phosphorylation-specific EGFR (Tyr 1068 ) antibody and PRSS1 antibody were obtained from Abcam.
