Abstract

SHOC2 leucine rich repeat scaffold protein (SHOC2) has been identified as a positive regulator of the Ras pathway; however, the function of SHOC2 in breast cancer has rarely been explored. The current study investigated the effects of SHOC2 on breast cancer cell growth and evaluated its prognostic value in patients with breast cancer. The effects of SHOC2 on MCF‑7 and MDA‑MB‑231 breast cancer cells were studied using short hairpin RNA. In total, 120 pairs of formalin‑fixed, paraffin‑embedded breast cancer tissue specimens were compared to normal tissue using immunohistochemical staining. SHOC2 knockdown significantly inhibited MCF‑7 and MDA‑MB‑231 breast cancer cell proliferation, and induced cell apoptosis and cell cycle arrest. Additionally, the RAS‑MAPK/PI3K pathway was inhibited by SHOC2 knockdown. In a clinical study, the results revealed that high SHOC2 expression was associated with more aggressive clinical characteristics of breast cancer. Moreover, Kaplan‑Meier and Cox regression analyses indicated that SHOC2 expression was an independent prognostic factor for survival, suggesting that increased SHOC2 expression predicted a worse overall survival. This indicated that SHOC2 knockdown could affect breast cancer cell survival, and SHOC2 upregulation may be associated with a poor prognosis in patients with breast cancer.
