PVT1 and cancer: Recently, researchers have proved the potential value of lncRNAs and miRNAs in cancer screening, diagnosis, and treatment; for example, lncRNA PVT1 was found to regulate the progression of pulpitis by down‐regulating the expression of miR‐455‐5p 23, and lncRNA DCRF could regulate cardiomyocyte autophagy through targeting miR‐551b‐5p 24.
