Abstract: A pharmaceutical anticancer or anticancer drug-resistance composition for a cancer cell, containing a CAGE-derived peptide, is provided. The pharmaceutical anticancer composition contains an effective ingredient of the CAGE-derived oligopeptide with SEQ TD NO.1 or SEQ ID NO.2 and reduces anticancer drug resistance or exhibits an anticancer effect.

Abstract: Schistosomiasis mansoni is caused by flukes called Schistosoma(es) that enters the human body through the skin in Schistosoma infested waters. The Schistosomes travel from the skin into human blood vessels where they mate, produce antigen containing eggs that travel from the blood vessels into the small intestines, where they are released in the human feces. Male and female Schistosome mates in human blood vessels, male Schistosomes secrete a protein called TGR ? protein to the Trk receptor sites on the females Schistosomes membranes. The process stimulates the formation of chemical SmInAct in female Schistosomes, a chemical necessary for the female Schistosomes to produce eggs. This novel technique describes new methods to inhibit Trk receptor sites on female Schistosome membranes using Trk inhibitor agent to prevent TGR ? proteins from binding to the Trk receptor sites. Thus, preventing SmInAct from being created in female Schistosomes, preventing production of eggs and Schistosomiasis.
