Objective: This study aims to identify the changes in the expression of hypoxia-inducible genes in seven different cancer cell lines that vary in their oxygen levels in an attempt to identify hypoxia biomarkers that can be targeted in therapy. Profiling of hypoxia inducible-gene expression of these different cancer cell lines can be used as baseline data for further studies.
Methods: Human cancer cell lines obtained from the American Type Culture Collection were used; MCF7 breast cancer cells, PANC-1 pancreatic cancer cells, PC-3 prostate cancer cells, SHSY5Y neuroblastoma brain cancer cells, A549 lung cancer cells, and HEPG2 hepatocellular carcinoma.
