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.

Description

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].

In Vitro

Dinitramine (2-20 μM; 24 h) reduces the viability and proliferative potential of TM3 and TM4 cells. Treatment with 20 μM dinitramine decreases the viability of TM3 cells to 78.7% and that of TM4 cells to 84.7%, and reduces the proliferative potential of both cell lines to below 50%[1].
Dinitramine (10-20 μM; 6 days) reduces the spheroid density and area of TM3 and TM4 cells in 3D culture systems; treatment with 20 μM decreases the spheroid density of TM3 cells by 22% and the area by 12%, while treatments with both 10 μM and 20 μM significantly reduce the spheroid density and area of TM4 cells[1].
Dinitramine (0-20 μM; 24 h) induces cell cycle arrest and cell death in TM3 and TM4 cells, inhibits the mRNA expression of cell cycle progression genes *Ccnd1*, *Cdk4* and *Ccne1* in cells, and activates endoplasmic reticulum stress in cells[1].
Dinitramine (0-20 μM) increases cytosolic and mitochondrial matrix calcium levels in TM3 and TM4 cells; treatment with 20 μM elevates the cytosolic calcium level to 230% in TM3 cells and to 300% in TM4 cells, while increasing the mitochondrial matrix calcium level to 230% in both cell lines[1].
Dinitramine (5-20 μM; 30 min) activates the Mapk signaling pathway and inactivates the Pi3k/Akt signaling pathway in TM3 and TM4 cells; treatment with 20 μM for 30 min upregulates the levels of phosphorylated Erk1/2, P38 and Jnk, while downregulates the levels of phosphorylated Akt and Rps6kb1 in both cell lines[1].
Combined treatment with dinitramine (20 μM; 24 h) and calcium regulators restores the proliferative potential of dinitramine-treated TM4 cells, but fails to restore that of TM3 cells[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.
