In cigarette smoke-induced and inflammation-associated lung cancer development, cigarette smoke extract (CSE) activates tumor necrosis factor-alpha (TNF-α) secretion from macrophages. TNF-α converting enzyme (TACE), also known as α-Secretase or ADAM17 (A Disintegrin and Metalloprotease), is a member of the ADAM family of metalloproteases. TACE mediated ectodomain shedding leads to the conversion of the inactive TNF-α precursor into the active mature pro-inflammatory cytokine. The SensoLyte 520 TACE (α-Secretase) Activity Assay Kit was used to detect TACE activity in CSE-activated macrophages. This assay is reliable, reproducible and easy to carry out in 96 well plate format.
在香烟烟雾诱导和炎症相关的肺癌发展过程中,香烟烟雾提取物(CSE)可激活巨噬细胞分泌肿瘤坏死因子-α(TNF-α)。TNF-α转换酶(TACE),也称为α-分泌酶或ADAM17(一种去整合素和金属蛋白酶),是金属蛋白酶ADAM家族的成员。TACE介导的胞外域脱落导致无活性的TNF-α前体转化为有活性的成熟促炎细胞因子。使用SensoLyte 520 TACE(α-分泌酶)活性检测试剂盒检测CSE激活的巨噬细胞中的TACE活性。该检测方法可靠、可重复,且易于以96孔板形式进行操作。
