Linc00673 was at first identified to be significantly upregulated in NSCLC tissues compared with normal lung tissues, and Shi et al. verified that linc00673 could promote cell proliferation via interacting with the H3K4 demethylase LSD1 and suppressing NCALD expression [24, 49]. The gene discussed is KDM1A; the disease is non-small cell lung carcinoma.
