Briefly speaking, we first analyzed GPX4 positively-correlated lncRNAs from Starbase database (http://starbase.sysu.edu.cn/), and then we screened lncRNAs highly expressed in cancer tissues compared with normal tissues in TNMplot (https://tnmplot.com/analysis/), and investigated the survival of lncRNAs in Kaplan Meier plotter (http://kmplot.com/analysis/). The gene discussed is GPX4; the disease is cancer.
