Abstract

The present study aimed to determine the influence of the Wnt/β-catenin signaling pathway on the proliferation, invasion, migration and apoptosis of malignant melanoma (MM) A375 cells. β‑catenin interfering lentivirus liquid (β‑catenin‑RNAi‑LV) and empty vector lentivirus liquid (β‑catenin‑negative‑LV) were used to infect A375 cells. Infected cells were obtained and marked as A375‑RNA interference (A375‑RNAi) or A375‑negative, respectively. Western blotting was used to measure the expression of β‑catenin in infected cells and uninfected cells were utilized as a control. An MTT assay was adopted to measure cell proliferation and the clone formation of cells was assessed. In addition, the Transwell method was used to detect cell invasion and migration in vitro and flow cytometry was utilized to determine cell apoptosis. Western blot analysis demonstrated that β‑catenin was highly expressed in uninfected A375 cells but exhibited reduced expression in A375‑RNAi cells. These results indicate that β‑catenin expression is effectively silenced by β‑catenin‑RNAi‑LV. The proliferative and clone forming abilities of A375‑RNAi cells were impaired compared with A375‑negative and A375 cells. Additionally, the apoptosis rate was increased and the invasion and migration of A375‑RNAi cells was decreased. However, no significant differences were identified in the proliferation, clone formation, apoptosis rate, invasion and migration of A375‑negative cells compared with A375 cells. Therefore, the current study demonstrated that the inhibition of β‑catenin expression or activity inhibits cell proliferation and invasion and migration, further downregulating the expression of anti‑apoptotic genes and accelerating cellular apoptosis.
