Abstract

Osteosarcoma is a common type of human carcinoma, which exhibits a high metastasis and recurrence rate. Previous studies have indicated that long non‑coding RNA phosphatase and tensin homolog pseudogene 1 (lnPTENP1) has tumor suppressive action by modulating PTEN expression in different types of tumor cells. However, the potential mechanism by which lnPTENP1 has an effect in osteosarcoma cells remains elusive. In the present study, the role of lnPTENP1 in osteosarcoma cells was investigated and the possible mechanisms by which it functions were explored. It was revealed that lnPTENP1 transfection significantly inhibited osteosarcoma cell growth, proliferation, migration and invasion. LnPTENP1 transfection also significantly promoted apoptosis in Mg63 cells treated with tunicamycin. Further analysis revealed that lnPTENP1 transfection regulated osteosarcoma cell growth via the PI3K/AKT signaling pathway. In vivo assays revealed that lnPTENP1 transfection significantly inhibited osteosarcoma tumor growth and significantly increased the protein expression and phosphorylation levels of PI3K and AKT. In conclusion, the results of the present study indicated that lnPTENP1 may inhibit osteosarcoma cell growth via the PI3K/AKT signaling pathway, which may be a potential novel target for human osteosarcoma therapy.
