Abstract

The purpose of the present study was to investigate the expression profile of leucine‑rich repeat‑containing protein 8A (LRRC8A) in osteosarcoma and normal cortical bone, as well as its association with sex, age and tumor malignancy. Immunohistochemical staining of osteosarcoma tissue microarrays (TMAs) was performed to determine the protein expression of LRRC8A and compare them among different subgroups. The expression of LRRC8A in the nuclei and cytoplasm of U2OS tumor cells and MC3T3‑E1 osteoblast‑like cells was determined using reverse transcription‑quantitative PCR. Of all samples of the TMA for patients with osteosarcoma that were tested, 94% featured high cytoplasmic expression of LRRC8A, while in all normal bone tissue control groups, the gene was mainly expressed in the nucleus. In MC3T3‑E1 osteoblasts, the expression of LRRC8A at the RNA level was mainly in the cytoplasm. The difference in expression of LRRC8A between microarrays and osteoblasts was statistically significant. In U2OS osteosarcoma cells, LRRC8A mRNA was concentrated in the nuclei and cytoplasm. In osteosarcoma, the expression level of LRRC8A was not significantly associated with sex or age. In conclusion, LRRC8A was highly expressed in the cytoplasm of osteosarcoma cells and the degree of expression may be associated with the degree of tumor malignancy.
