Research Abstract

To monitor cancer circadian rhythm, DBPpromoter-luciferase (DBP-luc) stably introduced colon cancer cell line was established. We found heat shock (43C 1h) did not affects rhythm phase of DBP-luc cell. Additionally, hypoxia responsive element (HRE)-GFP was introduced to DBP-luc cell to monitor hypoxia and circadian rhythm simultaneously. To make DBP-luc / HRE-GFP stably introduced cell line by single transfection, we designed and made new gene constructs. We established the 3D in vitro DBP-luc cell culture system which mimics hypoxia of cancer tissue.
