查询词典 cofactor

Vitamin K acts as a cofactor in normal blood coagulation from the post translation modification of a number of plasma proteins such as prothrombin. Vitamin K has been the focus of considerable research demonstrating an anticancer potential.However, yet the mechanisms of action remain unclear. A number mechanisms has been proposed and focused on the oxidative model which increased redox-cycling of menadione and the production of ROS surpasses the oxidative capacity of the cell, resulting in cell death.

由过去文献报告指出，Vitamin K也具有抗癌的效果，但作用机制不是完全清楚，目前了解依作用机制分成2种模式，一则是氧化模式，透过氧化还原的方式大量产生过氧化物，增加细胞氧化的负担而进一步造成细胞死亡，另一则是非氧化模式由从转录因子来探讨，Vitamin K会促进特定的转录因子表现进而调控细胞周期停滞及细胞凋亡。

"Almost all enzymes are proteins ; many depend on a nonprotein cofactor, either a loosely associated organic compound (e.g., a vitamin) or a tightly bound metal ion (e.g., iron, zinc) or organic (often metal-containing) group."

Each group was subdivided into oldage (＞60 years) and middleage (＜60 years) subgroups. Polymorphism of ApoE, ApoE IE1, ApoH extron 8 G1025C (Try316Ser), ApoA5 SNP3 (1131T ＞C), S19W (C56C＞G) and ApoC3 (482C/T) were studied. Meanwhile the cofactor between ApoE and ApoE IE1, as well as haplotype of ApoA5＊3 ApoC3482TT were analyzed. The parameters of plasma lipids were measured through biochemistry.
