The roles of natural product in drug discovery and development cannot be over emphasised. It plays a vital role in human therapy and gives a better understanding on the cellular pathways.This study investigated the modulatory effects of partially purified fractions of Piper guineense Schumach. & Thonn. (Piperaceae), Zanthoxylum zanthoxyloides Lam. (Rutaceae), Amaranthus viridis L. (Amaranthaceae), Costus afer Ker-Gawl. (Zingiberaceae) and Catharanthus roseus (L.) G. Don. (Apocynaceae) on oestrogen receptor-? (ESR-?), tumour protein p53 (TP-53), retinoblastoma (RB) and NAD(P) H quinine oxidoreductase (NQO1) genes in cervical cancer cell line (HeLa cells). n-Hexane, ethylacetate, chloroform, and water fractions of 80% ethanol extracts of study plants were screened with brine shrimp lethality and water-soluble tetrazolium-1 (WST-1) cytotoxicity assay. HeLa cells were treated with 1:10 dilutions of IC50 concentrations of test fractions for 24 hours, total RNA was extracted, RNA quality was checked, and normalized to a baseline concentration. Gene expression was monitored by semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR). Results showed that ESR-? was downregulated (p < 0.05) by P. guineense-hexane, C. roseus-chloroform and A. viridis-ethylacetate fractions. TP53 gene was up-regulated (p < 0.05) by P. guineense-hexane and Z. zanthoxyloides-ethylacetate fractions. None of the test fractions caused an up-regulation in the expression of retinoblastoma gene. NQO1 gene was down-regulated (p < 0.05) by C. roseus-chloroform, P. guineense-hexane, A. viridis, C. afer, and Z. zanthoxyloides ethylacetate fractions. Our study provides scientific evidence of the possible anti-proliferative potentials of C. roseus-chloroform, P. guineense-hexane, ethylacetate fractions of A. viridis, C.afer, and Z. zanthoxyloides in cervical cancer.
