Bladder cancer (BCa) is one of the most common urinary malignancies in the world. Growing evidence suggests that epithelial-to-mesenchymal transition (EMT) is a major contributor for BCa metastasis. lncRNA small nucleolar RNA host gene 16 (SNHG16) has been reported as a tumor promoter in many cancers. This study aims to investigate the function and mechanism of SNHG16 on EMT in BCa. Quantitative RT-PCR (qRT-PCR) was used to determine the expression of SNHG16 in human BCa tissues and TGF-β-induced cells. Western blot (WB) was performed to evaluate the expression of EMT-related proteins. Transwell assay was exerted to assess the migration and invasion ability of SNHG16 in BCa. RNA pull-down assay was conducted to confirm the RNA-RNA interaction. The precise mechanism by which SNHG16 regulated EMT process in BCa was also explored. SNHG16 was found up-regulated in TGF-β-induced BCa cells and BCa tissues. Transwell assay showed that overexpression of SNHG16 significantly promoted the migration and invasion of BCa cells, whereas knock-down of SNHG16 caused the opposite effects. Then, the interaction between SNHG16 and miR-200a-3p was verified by dual-luciferase reporter assay and RNA pull-down assay. And the effects of knock-down or overexpression of SNHG16 on migration and invasion were reversed by co-transfecting miR-200a-3p inhibitors or mimics. This study first demonstrated that SNHG16 was responsible for EMT of BCa cells via miR-200a-3p/ ZEB1/ZEB2 axis. These results provided a potential therapeutic strategy for BCa treatment, especially in metastatic BCa.

Tumors or cancer of the URINARY BLADDER.
A growth differentiation factor that is secreted in response to cell stress and in response to MACROPHAGE ACTIVATION. In addition growth differentiation factor 15 demonstrates a diverse array of biological properties including the induction of cartilage formation, the inhibition of hematopoietic progenitor proliferation, and the induction of neuronal migration.
A HERNIA-like condition in which the weakened pelvic muscles cause the URINARY BLADDER to drop from its normal position. Fallen urinary bladder is more common in females with the bladder dropping into the VAGINA and less common in males with the bladder dropping into the SCROTUM.
An SHC-signaling adaptor protein that transduces PHOSPHOTYROSINE-dependent signals downstream of RECEPTOR PROTEIN-TYROSINE KINASES and non-receptor tyrosine kinases. It is required for TGF-BETA-induced CELL MIGRATION; NEOLPASM INVASION; and METASTASIS of BREAST NEOPLASMS; its SH2 DOMAIN is essential for tumor survival. It also functions in signaling downstream of ANGIOPOIETIN RECEPTOR TIE-2, regulating the migration of ENDOTHELIAL CELLS; and PHYSIOLOGIC NEOVASCULARIZATION.
A member of the S100 PROTEIN FAMILY that regulates INFLAMMATION and the immune response. It recruits LEUKOCYTES, promotes cytokine and chemokine production, and regulates leukocyte adhesion and migration. S100A12 can also function via binding to ADVANCED GLYCOSYLATION END PRODUCT-SPECIFIC RECEPTORS, to stimulate innate immune cells.
