Dinitramine 是一种除草剂 (herbicide)。Dinitramine 可激活睾丸细胞中的 Erk/P38/JNK/MAPK 通路,并使其中的 PI3k/Akt 通路失活。Dinitramine 可诱导睾丸细胞发生内质网应激、胞质及线粒体内钙稳态失调、细胞凋亡 (apoptosis),以及细胞周期基因表达下调。Dinitramine 会降低睾丸细胞的活力与增殖能力,并通过抑制微管蛋白 (tubulin) 合成来阻碍细胞分裂。Dinitramine 可诱导斑马鱼胚胎出现心脏发育异常、血管生成受抑、炎症反应、细胞凋亡及胚胎生长受损。

生物活性

Dinitramine is a herbicide. Dinitramine activates the Erk/P38/JNK/MAPK pathway and inactivates the PI3k/Akt pathway in testicular cells. Dinitramine induces endoplasmic reticulum stress, dysregulation of calcium homeostasis in the cytoplasm and mitochondria, apoptosis, and downregulated expression of cell cycle genes in testicular cells. Dinitramine reduces the viability and proliferation capacity of testicular cells, and inhibits cell division by suppressing the synthesis of tubulin. Dinitramine induces abnormal heart development, inhibited angiogenesis, inflammatory responses, apoptosis, and impaired embryonic growth in zebrafish embryos[1][2].

Dinitramine (5-20 μM; 30 min) 可激活 Mapk 信号通路,并使 TM3 和 TM4 细胞中的 Pi3k/Akt 信号通路失活;在两种细胞系中,20 μM 处理 30 min 均可上调磷酸化 Erk1/2、P38 和 Jnk 的水平,同时下调磷酸化 Akt 和 Rps6kb1 的水平[1]
Dinitramine (20 μM; 24 h) 与钙调节剂联合处理可恢复经 dinitramine 处理的 TM4 细胞的增殖潜能,但无法恢复 TM3 细胞的增殖潜能[1]

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
