CXCL10 enhances radiotherapy effects in HeLa cells through cell cycle redistribution.

ABSTRACT: Radiotherapy is a crucial treatment for cervical cancer, the second most common type of cancer in women worldwide. In this study, we investigated the effects of CXC chemokine ligand 10 (CXCL10) gene therapy combined with radiotherapy on cervical cancer using HeLa cells. TUNEL assay revealed that the apoptotic rate in the combined treatment of CXCL10 gene therapy and radiotherapy was greatly increased compared with that of CXCL10 or radiotherapy alone. Flow cytometry showed that CXCL10 overexpression in HeLa cells resulted in a prolonged G1 phase and shortened S phase at 72 h post-transfection. Western blot analysis revealed that p27(Kip1) was up-regulated in CXCL10-treated HeLa cells; however, cyclin E was down-regulated. These results indicate that the combination of CXCL10 gene therapy a
