Abstract
Provided are a composition including a Kang AI 1 (KAI1) polypeptide or a gene encoding the same, for inhibiting angiogenesis, and a use thereof, and more specifically, a composition including a KAI1 polypeptide or a gene encoding the same, for inhibiting angiogenesis, and a pharmaceutical composition for preventing and treating cancer. Further, KAI1, which is expressed in a pericyte rather than in an endotheliocyte, can inhibit angiogenesis by functioning as a negative angiogenic regulator, and thus the subject matter can inhibit angiogenesis due to a known angiogenesis factor by various methods such as a method using a supernatant in a pericyte which forcefully increases KAI1 or in which KAI1 is forcefully increased, a method using a KAI1 protein, or a method for inhibiting a Src-Pkc pathway provoking the degradation of KAI1. Further, the subject matter can identify the severity of a cancer patient by identifying the expression of KAI1 in a pericyte.
