SOX2 and prostate carcinoma: At the present stage, research regarding the effect of LncRNAs on CSCs mainly concentrates on HCC, prostate cancer, breast cancer, and glioma, and researchers have found that the mechanisms of LncRNAs in different tumors are not consistent (see Additional file 1), which include changes in histone modification, the regulation of classic stem cell-related signaling pathways such as SOX2/KLF4, the induction of EMT, and the inhibition of miRNA function.
