The antitumor activity of Momordica anti-human immunodeficiency virus protein of 30 kDa (MAP30) has been proved. However, the role of MAP30 on tumor metastasis has not yet been identified. For this purpose, we investigated this effect and underlying mechanism of MAP30 in bladder cancer (BC). Here, we reported that MAP30 significantly inhibited the cell proliferation and clone formation of 5637 and T24 cells in vitro by promoting apoptosis and cell cycle arrest. We also found MAP30 inhibited cell migration and invasion by suppressing the epithelial/mesenchymal transition (EMT) process. Moreover, the Affymetrix GeneChip assay revealed that MAP30 significantly changed gene expression profile in T24 cells, especially the genes in cell cycle regulation pathways. After the Ingenuity Pathway Analysis, we predicted that NUPR1 was the most important upstream regulator. Subsequently, we verified that the AKT and EMT signaling pathways were inhibited by MAP30 treatment in T24 cells. In conclusion, MAP30 treatment inhibited the progression of human BC, especially cell migration and invasion through suppressing AKT pathways.
