Abstract
Andiroba (Carapa guianensis Aubl) is an Amazonian plant whose oil has been widely used in traditional medicine for various purposes, including anti-inflammation. Research reports indicate that the oil can confer antitumor activity due to the presence of fatty acids, which can directly influence cell death mechanisms. Thus, andiroba oil (AO) has gained interest for its potential to be used in antineoplastic therapies. Here, we report an in vitro analysis of the cytotoxic and mutagenic potential of AO in the gastric cancer cell line, ACP02. Cell survival was assessed by the MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] assay, differential staining with ethidium bromide and acridine orange assessed apoptosis-necrosis, and mutagenesis was assessed by the micronucleus test. The apolar oil was first diluted in 0.1% dimethyl sulfoxide (DMSO) and then further diluted to six concentrations (0.01, 0.1, 1, 10 and 100 μg/mL and 1 mg/mL) in RPMI medium. Controls included RPMI alone (negative control) and 0.1% DMSO diluted in medium (vehicle control). The MTT test showed that AO significantly reduced cell viability (P < .05) only when the highest tested concentration was applied for 48 hours. The apoptosis/necrosis test ...Continue Reading
