HSPA5 and cervical carcinoma: In a previous study, researchers screened out differentially expressed lncRNAs in cervical cancer related to glucose-regulated protein 78 (GRP78) from a database; these researchers demonstrated that LINC00294 is positively correlated with GRP78 and that knock down of GRP78 in HeLA cells significantly downregulates LINC00294, which inhibits the Hedgehog pathway and regulates cell cycle arrest, thereby suggesting that LINC00294 may be a diagnostic target for cervical cancer [44].
