Background

N,N’-Dinitrosopiperazine (1,4-Dinitrosopiperazine; DNP) is a carcinogen with specificity for nasopharyngeal epithelium and facilitates NPC metastasis. N,N’-Dinitrosopiperazine regulates multiple signaling pathways through protein phosphorylation, including LYRIC at serine 568[1].

N,N’-Dinitrosopiperazine (0.5-100 μM; 48 hours) has no inhibitory effects on the labeled 6-10B cells, and LDH activity is not significantly altered by DNP treatment in the 0.5-8 μM concentration range. However, it is cytotoxic from the concentration 10 μM[1].N,N’-Dinitrosopiperazine (2-8 μM; 24 hours) induces 6-10B cell invasion and motility in a dose-dependent manner. At 6 μM, when compares to the control group, DNP increases cell invasion at 421.7% and cell motility is increased by 328.2%[1].N,N’-Dinitrosopiperazine (6 μM; 24 hours) increases the expression of phospho-LYRIC s568 and LYRIC expression in CNE1 cells[1].

N,N’-Dinitrosopiperazine (injected into the tail veins; 40 mg/kg; 30 days) inhibits cell motility and invasion, and facilitates NPC metastasis in vivo. From a IHC result, Phospho-LYRIC expression is higher in the metastatic tumors of DNP-treated mice than in those of the untreated control mice[1].
