Abstract

Increasing evidence has suggested that microRNAs (miRNAs; miRs) are extensively involved in the progression of chondrosarcoma (CHS). However, few studies have investigated the functional role of miR‑525 in CHS tissues and cells. In the present study, it was discovered that miR‑525 levels were decreased in CHS tissues and cells. Dual luciferase assays indicated that F‑spondin 1 (SPON1) is a target gene of microRNA (miR)‑525. In addition, miR‑525 overexpression suppressed SW1353 cell migration and invasion and enhanced SW1353 cell apoptosis. Increased SPON1 expression levels were identified in CHS tissues and cell lines. Furthermore, miR‑525 overexpression significantly suppressed the activation of focal adhesion kinase (FAK)/Src/phosphatidylinositol‑4,5‑bisphosphate 3‑kinase (PI3K)/protein kinase B (Akt) signaling in CHS cells; this suppression led to SPON1 silencing. In comparison, the SPON1 knockdown‑mediated inactivation of FAK/Src/PI3K/Akt signaling was inhibited by inhibiting miR‑525. In summary, the present study revealed that decreased miR‑525 levels could enhance CHS malignancy as decreased miR‑525 binding to the 3' untranslated region of SPON1 activates FAK/Src/PI3K/Akt signaling.
