T-DNA Transmision and Tumor Inducing(TI) Effect of Agrobacterium tumefaciens on Solatium nigrum 致瘤农杆菌对龙葵的致瘤作用及其T-DNA的转移
Objective To set up a cell model of human tumor cell inducing differentiation. 目的建立肿瘤细胞诱导分化的模型。
It can kill or inhibit tumor by inducing immune cells to proliferate and enforcing their activity, making cytokines secret, enhancing tumor cell apoptosis by Fas - FasL, and inhibiting tumor vascularization. 它可以通过诱导免疫细胞的增殖并提高其活性、促进各种细胞因子的产生及分泌、增强Fas-FasL介导的肿瘤细胞的凋亡、抑制肿瘤的血管形成等机制杀伤或抑制肿瘤。
A number of evidences have shown that arsenic is of property to promote tumor by inducing intracellular signal transduction, activating transcription factors and changing the expression of genes that are involved in promoting cell growth, proliferation and malignant transformation. 大量研究表明砷可以通过诱导信号转导通路,激活转录因子和改变控制细胞生长、增殖和恶性转化的基因表达来发挥促癌作用。
