COPRISIN is an antibiotic substance extracted from Copris tripartitus. This study is intended to identify various cell biological stimuli that COPRISIN, widely known as an antibacterial substance, has on human cells and to identify its molecule mechanism. A variety of human cell lines were divided into epithelial cells including kidney cells or womb cells, and immunocyte including T cells or macrophages and, after their being cultivated and maintained, cell biological changes of the respective cells according to COPRISIN treatment were compared. As a result, it was confirmed that, different from other experiment cells, COPRISIN specifically caused cell kill in T cells and macrophages. That is, fragmentation of DNA, typical characteristics observed in the process of apoptosis, was confirmed in the nucleus of cells dying owing to COPRISIN treatment. An Apoptosis process is one dependent upon activity of caspase family protein, it was proved that COPRISIN medium cell kill process was one through a caspase-independent route such as AIF. Though it was found out that transcription of TNF-α and extracellular TNF-α secretion increased in blood cells stimulated by COPRISIN, it was also confirmed that TNF-α was a major medium factor in a COPRISIN induced cell kill process from the fact that a cell kill process by COPRISIN was not inhibited at all with TNF-α inhibiting antibody treatment. Above results revealed that COPRISIN, different from other tissue origin cells including kidney cells, can specifically induce apoptosis in immunocyte, which is caused by a caspase-independent cell signal transmission route.
