Article Details
While African Health Sciences has been freely accessible online there have been questions on whether it is Open Access or not. We wish to clearly state that indeed African Health Sciences is Open Access. There are key issues regarding Open Access needing clarification for avoidance of doubt:
- 1. Henceforth, papers in African Health Sciences will be published under the CC BY (Creative Commons Attribution License) 4.0 International. See details on https://creativecomons.org/)
- 2. The copyright owners or the authors grant the 3rd party (perpetually and in advance) the right to disseminate, reproduce, or use the research papers in part or in full, format/medium as long as:
- No substantive errors are introduced in the process
- Attribution of authorship and correct citation details are given
- The referencing details are not changed.
Should the papers be reproduced in part, this must be clearly stated.
- 3. The papers will be freely and universally accessible online in an easily readable format such as XML in at least one widely recognized open access repository such as PUBMED CENTRAL.

Identification of HPV16’s E6 gene in suspected cases of cervical lesions and docking study of its L1 protein with active components of Echinacea purpurae
Abstract
Background: HPV 16 is the primary etiologic agent of cervical cancer and the presence of L1 and E6 oncoproteins are largely responsible for its virulence. It was the objective of this study to identify HPV16 isolates from suspected cases of cervical cancer at Specialist Hospital Sokoto and Sir Yahaya Memorail Hospiatal Birnin Kebbi, Nigeria and also to identify
potent HPV16’s L1 protein inhibitor using in silico analysis.
Methods: A total of 144 cervical samples consisting of 21 low grade squamous intraepithelial lesion, 6 high grade lesion and 117 negative pap smears were collected. The samples were subjected for molecular detection using PCR targeting E6 gene of the virus. Data generated for the molecular prevalence was statistically analyzed using Chi-square method. AutoDock Vina was used to carry out the molecular docking between 2hr5 and Chicoric acid, curcumin and Echinacoside.
Results: Out of the 144 samples, 24 samples were positive for the PCR representing 16.9% molecular prevalence rate. There is statistically significant association between cyto-diagnoses and presence of HPV16 (P < 0.05). Docking analysis showed that the Chicoric acid components of Echinacea purpurae have strong binding affinity (-8.7 kcal/mol) to the L1 protein of the HPV.
Conclusion: This study provides data on HPV 16 epidemiology in northern Nigeria, and also provides novel evidence for consideration on certain interacting residues, when synthesizing Anti-HPV compounds in the wet lab.
Keywords: HPV; Echinacea purpurae; chicoric acid; echinacoside; curcumin.
