LncRNA HCG18 facilitates melanoma progression by modulating miR-324-5p/CDK16 axis
AJTR Copyright © 2022..
OBJECTIVE: LncRNA HCG18 has been reported to act as a tumor promoter in gastric cancer, hepatocellular carcinoma and nasopharyngeal carcinoma. However, the role of HCG18 in melanoma is still not clear. In this study, we detected the expression and molecular function of HCG18 in melanoma.
METHODS: The expression of HCG18 in melanoma cell lines and 50 pairs of melanoma and corresponding non-cancer tissues was detected by RT-qPCR. The relationship between HCG18 and clinicopathology was analyzed. We used HCG18 overexpressing melanoma cell lines A375 and M14, and si-HCG18 to knock down HCG18 expression. CCK-8, clone formation, Transwell assay and FCM were used to explore the effect of HCG18 knockdown on cell proliferation, migration, invasion and apoptosis in melanoma cells. Bioinformatics software was used to predict the downstream miRNA regulated by HCG18, and the downstream target genes regulated by miR-324-5p. Dual-luciferase reporter assay and RNA pull-down assay were used to verify whether miR-324-5p was related to the predicted sequence of HCG18.
RESULTS: HCG18 was highly expressed in melanoma tissues and cells. Besides, we found that HCG18 was closely correlated with thickness, TNM stage and metastasis. Functional experiments discovered that HCG18 knockdown restrained cell proliferation, migration and invasion, while promoted cell apoptosis in melanoma cells. HCG18 was confirmed to be a sponge of miR-324-5p, and CDK16 might be a downstream gene of miR-324-5p. HCG18 was found to reverse the effect of miR-324-5p by upregulating CDK16 expression in melanoma cell proliferation, apoptosis, migration and invasion in vitro.
CONCLUSION: This study indicated that HCG18 played an essential role in the pathogenesis of melanoma and suggested that HCG18 might be a potential target for the treatment and diagnosis of melanoma.
