CCND1 and non-small cell lung carcinoma: Our integrated transcriptomic and experimental analyses reveal a novel ceRNA regulatory axis in NSCLC pathogenesis, wherein the lncRNAs LOC729919 and LOC100134412 function as molecular sponges for miR-145-3p, thereby derepressing the expression of the metastasis-associated ECM regulator FN1 and the cell cycle controller CCND1.
