摘    要:目的:用蛋白酶酶解乌贼墨,经纯化获得寡肽,并对其进行抗肿瘤活性研究。方法:通过胰蛋白酶酶解获得乌贼墨酶解物,将酶解液用超滤、G-25分子筛凝胶层析进行分离纯化,高效液相进行纯度检测。分离纯化得到的寡肽进行氨基酸序列检测,并用CCK-8检测寡肽对DU-145细胞增殖的影响和HE染色方法观察其对细胞形态的影响。结果:乌贼墨寡肽的N端氨基酸序列为:Gln-Pro-Lys,得率为1.82%。将寡肽进行抗肿瘤活性研究,发现寡肽对DU-145细胞有明显的增殖抑制效应,且有浓度依赖性。HE染色结果显示了寡肽使细胞形态发生不规则变化,失去原有的恶性表型。结论:用酶解方法制得的乌贼墨寡肽有明显的抗肿瘤活性。

关 键 词:乌贼墨  酶解  寡肽  抗肿瘤  NGln-Pro-Lys

Abstract:AIM: To investigate the antitumor effect of peptides from Sepia ink by enzymatic hydrolysis. METHODS: Sepia ink was hydrolyzed with trypsin to prepare peptides; hydrolysates were isolated by ultrafiltration and purified using G-25 gel filtration. The purity of the sepia ink oligopeptides was demonstrated by HPLC and its peptide sequence was detected. Then CCK-8 method was employed to measure cellular viability, and HE staining was used to detect cell morphological change. RESULTS: An oligopeptide was obtain...
Keywords:Sepia ink  Enzymatic hydrolysis  Oligopeptide  Antitumor  N Gln-Pro-Lys
