Tokyo, July 18 (QNA) - A team of Japanese researchers have created artificial amino acids highly permeable to cancer cells.
The researchers at Aichi Cancer Center Research Institute tested new types of amino acids called peptides "CPP44" on cancer cells in human liver and white blood cells, Japan's (NHK World) website reported.
The substance penetrated tumor cells without damaging healthy cells.
The researchers also combined the peptides with anti-cancer agents to test on cancer cells in mice. They found that tumor sizes shrank by less than half.
They also discovered another type of peptides they formulated worked in a similar way on different kinds of cancer cells. (QNA)
