LINC00470 promotes malignant progression of testicular germ cell tumors.
Background: Testicular germ cell tumor (TGCT) is a common malignant tumor in adolescents. Now, many long non-coding RNAs (LncRNAs) have been found to have an important function in TGCT. LINC00470 is specifically and highly expressed in TGCT, however, there is still no definite information concerning its role and underlying mechanism in TGCT. The purpose of this research was to look into the involvement of LINC00470 in TGCT and its intrinsic mechanism.
Methods and results: UCSC and GEPIA2 databases were used to analyze the expression of LINC00470, and the BEST website was used to perform GSEA enrichment analysis, immune infiltration analysis, and drug susceptibility analysis. SiRNA transfection was used to silence LINC00470 in TCAM-2 and NCCIT cells. Clone formation and Transwell assays were performed in TGCT cells to confirm the effects of LINC00470 on clone formation, migration, and invasion. Western Blot was performed to determine the expression of proteins related to the EMT and AKT signaling pathways. LINC00470 was specifically highly expressed in TGCT, and played a role in promoting tumor cell clone formation and cell metastasis by affecting the TGF-β and PI3K-AKT-mTOR signaling pathways to regulate the epithelial-mesenchymal transition (EMT) process; LINC00470 may also play a pro-tumor role by negatively regulating immune infiltration; in addition, the expression of LINC00470 was negatively correlated with the chemosensitivity of cisplatin in TGCT patients.
Conclusions: LINC00470 may play a significant role in the etiology and metastasis of TGCT through EMT and AKT-mediated signaling pathways.
期刊介绍：
Molecular Biology Reports publishes original research papers and review articles that demonstrate novel molecular and cellular findings in both eukaryotes (animals, plants, algae, funghi) and prokaryotes (bacteria and archaea).The journal publishes results of both fundamental and translational research as well as new techniques that advance experimental progress in the field and presents original research papers, short communications and (mini-) reviews.
