精氨酸对肿瘤生长和机体营养的影响已研究多年,但饮食中精氨酸对肿瘤生长的作用仍未阐明。一般认为,正常及肿瘤细胞体外培养时精氨酸是比需的,因此作者假设,在体内的肿瘤细胞增殖可能也依赖饮食中的精氨酸,进而研究了饮食中供给和缺失精氨酸对体内肝转移性肿瘤生长的作用,以及体外培养时两种条件下肿瘤细胞增殖的情况。 The effect of arginine on tumor growth and body nutrition has been studied for years but the role of arginine in the diet on tumor growth remains unclear. Arginine is generally believed to be more specific than normal when cultured in vitro and in vivo, so the authors hypothesize that in vivo tumor cell proliferation may also be dependent on arginine in the diet and that the arginine supply and absence in the diet is studied The role of in vivo liver metastatic tumor growth, and the proliferation of tumor cells in both conditions in vitro.
