| Title | Spatiotemporally Deciphering the Unknown Role of Persistent HPV Infection in Precancer to Cervical Cancer Progression: Integrating Single-Cell RNA-Sequencing Landscape and Spatial Transcriptomics Atlas |
| Organism | Homo sapiens |
| Overall design | Nine cervical tissue samples of different disease stages from normal, HPV-infected, precancer to cancer were collected from colposcopy examination and analyzed using scRNAseq and spatial transcriptomics . |
| Summary | The mechanism underlying the cervical carcinogenesis mediated by persistent HPV infection remains elusive. Here we pioneeringly deciphered both temporal transition and spatial distribution of the cellular subsets during the disease progression from normal cervix, precancer lesions to cervical cancer by integrating scRNA-seq with ST. We not only identified three ‘HPV-related epithelial clusters’ unique to normal, HSIL and cervical cancer respectively, but also discovered node genes which potentially determined the disease progression. Moreover, we observed a gradual transition of multiple immune cells from positive immune response to dysregulation and exhaustion, to an immune-suppressive microenvironment during the malignant program. Besides, the cellular interaction analysis further verified a ‘homeostasis-balance-malignancy’ change within cervix microenvironment during disease escalation. Together, these findings not only deciphered mysterious persistent HPV infection spatiotemporally from the process of precancer to cervical cancer but also provided unprecedented possibilities for accurate diagnosis, precise treatment and prognosis evaluation for precancer and cervical cancer. |
