From: Induction of long intergenic non-coding RNA HOTAIR in lung cancer cells by type I collagen
Elevated expression of HOTAIR and Col-1 in human NSCLC. A) The RNA levels of HOTAIR were measured using qRT-PCR in the RNA samples extracted from the cancer and non-cancer tissue specimens of the patients with NSCLC. The RNA levels of HOTAIR were measured using qRT-PCR and normalized to the house keeping gene β-actin. B) Similar to part A except that the mRNA levels of Col-1 were compared between cancer and non-cancer tissues. Means and standard deviations were obtained from 26 pairs of cancer and non-cancer specimens. ** and *** indicated a P value < 0.01 and 0.001 respectively as determined by paired two tail student T test.
