Antigenotoxic Effect Of Ferulic Acid In 7,12-Dimethyl Benz(A)- Anthracene (Dmba) Induced Genotoxicity

Abstract: The antigenotoxic effect of ferulic acid was carried out by evaluating the cytogenetic markers, the micronuclei frequency and chromosomal aberrations, in the bone marrow of hamsters in 7,12-dimethylbenz(a)anthracene (DMBA) induced genotoxicity. Genotoxicity was induced in experimental hamsters by single intraperitoneal injection of DMBA (30mg kg -1 b.w). Pretreatment of ferulic acid orally at a dose of 40mg kg -1 b.w for five days significantly reduced the frequency of micronucleated polychromatic erythrocytes… Show more

“…Micronuclei frequency is a sensitive indicator of genetic/ mutagenic damage (Balakrishnan et al, 2007;Wu et al, 2004). DMBA is a potent genotoxic agent that causes the alteration of normal bone marrow cells when administered into the animals (Sugunadevi et al, 2012) and the effect is retained even after a long period (Balakrishnan et al, 2007). A hallmark of neoplastic transformation is the accumulation of genetic lesions which can be characterized by having increased micronuclei frequency.…”

“…W testach in vitro na komórkach eukariotycznych wykazano działanie antygenotoksyczne kwasu ferulowego wobec następujących czynników mutagennych: nadtlenku wodoru [21], nikotyny [25], menadionu [87] i promieniowania gamma [98][99][100][101]. Wykonano również testy in vivo, w których wykazano aktywność genotoksyczną wobec promieniowania gamma [99,100,102,103], nikotyny [104], benzo(a)pirenu [24] oraz 7,12-dimetylobenzo(a)-antracenu [105], natomiast brak aktywności wobec mitomycyny-C [27,88]. Wśród proponowanych przez badaczy mechanizmów działania antygenotoksycznego jest działanie antyoksydacyjne [14,25,36,97,99,104], wiązanie z DNA i blokowanie wiązania mutagenu [25], hamowanie aktywacji mutagenu [21], wiązanie z mutagenem [24] i indukcja enzymów detoksyfikacyjnych [24].…”
