LncRNA CHRF, a sponge of miRNA‐10b, promoted cell proliferation and epithelial‐mesenchymal transition (EMT) process in prostate cancer.9 LncRNA ZEB1‐AS1 mediated the miR‐200c/141‐ZEB1 axis to facilitate tumor growth and cell metastasis in glioma cancer.10 LncRNA SNHG14, which was identified as an oncogene, boosted the development of cervical cancer via regulating miR‐206 and targeting YWHAZ.11 Previous investigations also indicated that a variety of lncRNAs were participated in the regulation of LUAD development. The gene discussed is PTGDR; the disease is Familial prostate cancer.
