From: Regulatory effects of COL1A1 on apoptosis induced by radiation in cervical cancer cells
The effects of COL1A1 in cervical cells after treating with radiation. a The expression of COL1A1 depended on the the increasing dose of radiation. *P < 0.005 for 4 Gy group vs 0 Gy group in Hela and CaSki cells. b Colony formation of different cells to X-ray radiation was detected. The images of the colonies were stained with 0.5% crystal violet in CaSki and Hela cells. c Survival fraction of different cells to a dose of X-ray radiation (0–10 Gy). **P < 0.01 vs 0 Gy
