Abstract

ABSTRACT Exposure to N-nitroso compounds (NOCs) in our environment via pesticides, tobacco, and smoked meat can be potentially carcinogenic. The induction of N-N’ ethylnitrosourea (ENU), a genotoxic NOC, leads to leukemogenesis. The study aimed to explore the ameliorating effect of the Ayurvedic herb Eclipta alba on the bone marrow cells of ENU-induced leukemic mice. Eclipta alba is investigated for its anti-cancer effect on various cell lines, but never on haematological malignant models. Theefficacy of the extract was explored on leukemia by changes in body weight, survivability, peripheral blood hemogram, bone marrow cytological, histological, and cell culture studies pre-and post-treatment. The treated group revealed significant immunomodulation of the expressional profile of NF-kB family and IL-1β in marrow cells, by flow-cytometry, and immunofluorescence study. Through our experimental endeavour we depicted the cellular mechanism, signaling modality and tried to establish the anti-cancer potency of Eclipta alba on ENU-induced leukemia.
