Furthermore, the addition of PKC agonists, such as phorbol myristate acetate (PMA), and tumor necrosis factor alpha (TNF-alpha), mimicked the phagocytic enhancing effect of sodium azide.

Sodium azide, an inhibitor of catalase, reduced the increased sensitivity of mC5 and C33 cells to TNF-alpha to the level of toxicity found with control Hp cells.

In contrast, chromatin condensation and ladder-like DNA fragmentation were not detected in L929 targets dying by necrosis from exposure to heat, repeated cycles of freeze-thaw, and sodium azide.

Atherosclerosis. 2008 Jan;196(1):129-35. Epub 2007 May 24.

However, recent in vitro studies raised the possibility that the effects of CRP are caused by biologically active contaminants such as sodium azide and endotoxin.
In human mononuclear cells, CRP-induced production of tumor necrosis factor-alpha (TNF-alpha), interleukin-1 beta (IL-1 beta), and matrix metalloproteinase-9 (MMP-9) in a concentration-dependent manner.

Furthermore, an evident upregulation of PAR-1 in cultured primary astrocytes also occurred following exposure to lipopolysaccharide (LPS) (a well-known inductor of glial cell activation) whereas other neurotoxic agents (such as staurosporine, hydrogen peroxide and sodium azide), which are known to induce cell death, were unable to determine any PAR-1 variation.
Furthermore, after exposure to TMT and LPS, the levels of tumor necrosis factor-alpha and interleukin-1beta were also increased in astrocyte cultures, suggesting that the PAR-1 upregulation we have detected may be involved in glial inflammatory response rather than in cell death.

This phenomenon was abrogated by cytochalasin and sodium azide.

The Fas/Apo-1 molecule is a member of tumor necrosis factor/nerve growth factor (TNF/NGF) receptor family and is able to induce apoptosis in various type of malignant cells, including most of the human leukemia T-cells.
This observation seemed specific to Fas-mediated apoptosis, because calcium ionophore A23187 or sodium azide failed to repress the expression of cdks.
