| Summary: | Abstract Osteosarcoma (OS) is the second most common primary malignant bone tumors in adolescents that causes cancer‐related deaths. Previous studies have confirmed the promoting role of lncRNA HCP5 in the development of OS, but the specific mechanism is still not well understood. MiRNA levels were measured via RT‐qPCR and protein expression was detected via western blotting. Cell proliferation was analyzed by CCK‐8 assays and colony formations assay were conducted to measure colony formation ability. Dual‐luciferase reporter assay was performed to detect the targeting relationship between HCP5 and miR‐29b‐3p, and between miR‐29b‐3p and LOXL2. Wound healing assays and Transwell assays were conducted to verify the migration and invasion abilities of OS cells. Correlations between the levels of HCP5 and miR‐29b‐3p, and between miR‐29b‐3p and LOXL2 were determined by Pearson correlation coefficient analysis. MiR‐29b‐3p expression was decreased and HCP5 and LOXL2 levels were increased in OS tissues and cell lines. MiR‐29b‐3p could directly act on LOXL2 and knockdown of LOXL2 restrained the proliferation, migration, and invasion of OS cells. Moreover, transfection with sh‐HCP5‐1 and sh‐HCP5‐2 suppressed the malignant biological behavior of OS cells. HCP5 directly targeted miR‐29b‐3p, and promoted OS proliferation, migration, and invasion via the miR‐29b‐3p/LOXL2 axis. The lncRNA HCP5 may upregulate LOXL2 expression by targeting miR‐29b‐3p, thereby promoting OS proliferation, migration, and invasion. |
