CRABP2 and neoplasm of esophagus: As shown in Fig 3, the G1 phase of CRABP2 OE transfected stable EC109 cells was significantly less than that of Vector transfectedEC109 cells, whereas the S phase of CRABP2 OE transfected EC109 cells was much more than that of Vector transfected EC109 cells at both 24 h and 48 h, suggesting that CRABP2 might promote the G1/S checkpoint progression in esophageal tumor cells.
