| خلاصه مقاله | Background: Human papillomavirus (HPV) is a causative agent of cervical cancer, and is major etiologic agent of all the cases. The purpose of this investigation was to use RNAsequencing (RNA-seq) to screen the appropriate differentially expressed genes (DEGs) in the PBMCs for the progressive cervical cancer. Materials and Methods: Here we carried out RNAseq gene expression profiling of 45 peripheral blood mononuclear cells (PBMCs) from Tabriz (northwest of Iran) women, of the disease from cervical intraepithelial neoplasia I (CIN), CINII, CIN-III, healthy control (n= 15), and identified distinct RNA-seq gene expression signatures. The cDNA libraries were paired-end sequenced using an Illumina HiSeq 4000. All raw RNA-sequencing data analyses were performed using conventional RNA-sequencing analysis tools. Next, gene ontology analyses were carried out to elucidate the biological processes of DEGs. Finally, relative transcript abundance of selected DEGs was verified using qRT-PCR on additional validation groups. Results: Specifically, 14, 192, and 895 DEGs were identified for CIN-I, CIN-II and CIN-III, when compared with the healthy subjects. Overall, immune and inflammatory pathways were found to be significantly upregulated in patients with progressive stage. Additionally, we identified candidate signatures of disease progression such as CCL-2, CCL-5, IL-6, IL-10, TNF-α, and ANXA1 among others that were validated by qRTPCR in the samples used for RNA-seq studies as well in an independent set of additional samples. Conclusion: This study provides us with new insights into the biological function and potential cervical cancer and could facilitate the development of diagnostic markers of cervical cancer progression. |
