ancer cells do not need respiration, inhibiting GLUT1 may cause toxic effects
to all normal cells. 博主回复(2014-6-8 09:27):错!癌细胞不是不呼吸,而是以无
氧呼吸(糖酵解)为主,因为癌细胞缺氧。 .

n the endothelial cells of barrier tissues such as the blood–brain barrier.

lls. . [4]huangnigang1 2014-6-8 08:39 GLUT1不是oncogene, 没有突变致癌
功能,不可能成为抗癌药的靶位。GLUT1主要在红血球细胞表达,同癌症没有关系,但是
抑制GLUT1对正常细胞的功能将造成极大副作用。
