IL-32 promotes breast cancer cell growth and invasiveness
Interleukin (IL)-32 is a newly identified cytokine in humans and primates. It has been established that IL-32 may antagonize cancer growth. However, to the best of our knowledge, the direct effect of IL-32 on breast cancer cell growth has not yet been investigated. In addition, rodents lack the expr...

Sumario: | Interleukin (IL)-32 is a newly identified cytokine in humans and primates. It has been established that IL-32 may antagonize cancer growth. However, to the best of our knowledge, the direct effect of IL-32 on breast cancer cell growth has not yet been investigated. In addition, rodents lack the expression of IL-32; hence, the effects of IL-32 on breast cancer xenografts in nude mice have not been studied. The present study aimed to examine the potential regulatory effects of IL-32 on breast cancer cells in nude mice. The effects of IL-32 on tumor cell growth in cell cuture and a tumor xenograft model were investigated, as well as the effects of IL-32 on apoptosis. The effects of IL-32 on cell proliferation and apoptosis were investigated by MTT assay and TUNEL staining, respectively. The results revealed that IL-32 increases the proliferation rate of cancer cells and decreases the rate of apoptosis, In addition, IL-32 was found to enhance the growth of tumor xenografts in vivo. In summary, IL-32 may represent a useful therapeutic target for human breast cancer. |
