Abstract
- Prior studies have demonstrated that phosphatase of regenerating liver‑3 (PRL‑3) serves avital function in cell proliferation and metastasis in breast cancer. However, the molecular mechanisms underlying the function of PRL‑3 in breast cancer remain unknown. PRL‑3 expression was analyzed in 24 pairs of breast cancer and normal tissues using the reverse transcription‑quantitative polymerase chain reaction assay. The results of the present study identified that the expression of PLR‑3 in breast cancer tissues was increased 4.2‑fold, compared with normal tissues. Notably, overexpression of PRL‑3 significantly promoted the proliferation of cancer cells and inhibited endogenous p53 expression by downregulating the expression level of p14 alternate reading frame (p14ARF). In addition, decreased expression levels of PRL‑3 resulted in decreased breast cancer cell proliferation and increased expression level of p14ARF. These results suggested that PRL‑3 enhances cell proliferation by downregulating p14ARF expression, which results in decreased levels ofp53. The results of the present study demonstrated that PRL‑3 promotes tumor proliferation by affecting the p14ARF‑p53 axis, and that it may serve as a prognostic marker for patients with breast cancer.
