SNHG12 and neoplasm: SNHG7 promotes cell proliferation and metastasis via the PI3K/Akt pathway and correlates with radioactive iodine resistance; SNHG15 accelerates epithelial-mesenchymal transition via the Hippo-YAP1 pathway; SNHG12 drives malignant phenotypes by interacting with Wnt/β-catenin signaling; SNHG14 enhances tumor invasion through multiple miRNA axes.
