Abstract
Background: Hepatocellular carcinoma (HCC) is a common and leading cancer around the globe. This study
investigated the anticancer properties of extract of Annona senegalensis in N-diethylnitrosamine (DEN) - induced
hepatocellular carcinoma in male Wistar rats.
Methods: Rats were simultaneously induced with a combination of 100 mg/kg b.wt of DEN and 0.5 mL/kg of
carbon tetrachloride (CCl4) intraperitoneally once a week for three weeks in a row. Thereafter, animals were
treated with 100 mg/kg and 200 mg/kg b.wt of A. senegalensis extract daily for 21days. Analysis using gas
chromatography-mass spectrometry (GC–MS) was carried out to discover the phytoconstituents contained in the
n-hexane extract of A. senegelensis. The levels of liver function parameters and antioxidant enzyme activities were
determined via spectrophotometric analysis. Reverse transcriptase-polymerase chain reaction technique was
used to assess the gene expression patterns of BCL-2, P53, P21, IL-6, FNTA, VEGF, HIF, AFP, XIAP, and EGFR
mRNAs.
Results: Treatment of DEN-induced hepatocellular carcinoma Wistar rats with the extract caused significant
(p < 0.05) decrease in the activities of ALT and AST. It also resulted in a reduction of the concentration of MDA
and a significant increase (p < 0.05) in SOD and GSH activities. IL-6, BCL-2, VEGF, EGFR, XIAP, FNTA, and P21
mRNAs expressions were significantly (p < 0.05) downregulated after treatment. Histopathological analysis
revealed that the extract improved the liver architecture.
Conclusion: A. senegelensis n-hexane extract demonstrates its anticancer properties by improving the liver architecture, increasing the antioxidant defense systems, downregulating the pro-inflammatory, anti-apoptotic,
angiogenic, alpha-fetoprotein and farnesyl transferase mRNAs expression and hitherto up-regulate the expression
of tumor suppressor (P21 and P53) mRNAs.
