Abstract

Melanoma, as one of the most highly metastatic types of cancer, is resistant to current treatment methods, including popular targeted molecular therapy. Consequently, it is essential to develop a deeper understanding of the mechanisms involved in melanoma progression so that alternative treatments may be identified. To date, accumulating evidence supports the use of calpains, including calpain small subunit 1 (also known as Capn4 or CAPNS1), which affect cancer progression through many pathways, such as epithelial‑mesenchymal transition (EMT), the Wnt/β-catenin (β-catenin) and the nuclear factor κB (NF-κB) signaling pathways. The EMT pathway is well known as one of the most important events in tumor metastasis. The present study observed cross-talk among the EMT, β-catenin and NF-κB pathways. To identify the underlying mechanisms of Capn4 activity in melanoma cells, we determined Capn4 expression by gene chip and immunohistochemistral analyses in melanoma tissues and cells in vitro. The extent of apoptosis as determined by TUNEL assay, DAPI staining, and cleaved-caspase-3 assay was increased in human melanoma cells in which Capn4 expression had been knocked down when compared with untreated cells. Transwell assays and xenograft tumorigenicity studies were also performed to assess the effects of Capn4 on migration and invasion in vitro and tumor growth in vivo, respectively. The levels of β-catenin, vimentin, E-cadherin and N-cadherin were altered in human melanoma cells as determined by western blot analysis assay. Our study demonstrated that Capn4 is an underlying target for melanoma treatment.
