title: Effect of Punarnavine, an alkaloid from Boerhaavia diffusa, on cell-mediated immune responses and TIMP-1 in B16F-10 metastatic melanoma-bearing mice.
abstract: Effect of Punarnavine on the cell-mediated immune (CMI) response in metastatic condition was studied using C57BL/6 mice model. Administration of Punarnavine enhanced Natural Killer (NK) cell activity, antibody-dependent cellular cytotoxicity (ADCC) and antibody-dependent complement mediated cytotoxicity (ACC) and the activity was observed in treated group much earlier compared to the metastatic tumor-bearing control. Production of cytokines such as IL-2 and IFN-gamma were significantly enhanced by the administration of Punarnavine compared to the untreated metastatic tumor-bearing control. Peaks of pro-inflammatory cytokines such as IL-1beta, IL-6 and TNF-alpha were significantly lowered by Punarnavine administration compared to metastatic control. The level and expression of TIMP-1 was also enhanced by the administration of Punarnavine compared to metastatic tumor bearing control. These results indicate Punarnavine could enhance the immune response against metastatic progression of B16F-10 melanoma cells in mice.
