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 [Spatial Transcriptomics]

ABSTRACT: 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.

Expression data of mRNA and circRNA from HPV16 positive cervical cancer tissues, HSIL tissues and normal cervical epithelial tissues

Project description:CircRNAs have been found to regulate mRNA expression levels and serve an important role in cervix carcinogenesis. To explore the circRNA expression profiles during the development and progression of cervical cancer, we performed microarray analysis with total RNA in normal cervical epithelium(n=7), HPV16 positive high-grade squamous intraepithelial lesion (HSIL)(n=6), and HPV16 positive cervical squamous cell carcinoma tissues(n=7).

Genomic Sequencing of Cervical Cancers

Project description:<p>Cervical cancer is responsible for 10-15% of cancer related deaths in women worldwide. The etiological role of infection with high-risk human papilloma viruses (HPV) in carcinomas of the cervix is well established. In general, the development of cervical carcinomas follows a progression from persistent HPV infection through precancerous lesions to invasive cancer. Previous studies have implicated somatic mutations in PIK3CA, PTEN, TP53, STK11 and KRAS as well as chromosome-arm level copy number alterations in the pathogenesis of cervical carcinomas. Here, we report whole exome sequencing analysis of 118 cervical carcinoma-normal paired samples from patients in Norway and Mexico, as well as transcriptome sequencing of 80 cases and whole genome sequencing of 13 tumor-normal pairs. Novel somatic mutations include recurrent E322K substitutions in the MAPK1 gene encoding the ERK2 kinase and inactivating mutations in the HLA-B gene. In addition, recurrent somatic mutations in FBXW7, EP300, and NFE2L2 are novel in the context of primary cervical carcinomas. Analysis of HPV integration sites revealed recurrent integration into the RAD51B locus as well as co-occurrence of HPV genome integration and copy number gains within several genomic loci. These findings shed new light on the pathogenesis of cervical carcinomas and suggest potential novel therapeutic targets.</p>

circularRNA Sequencing of HPV16 positive cervical cancer tissues, HSIL tissues and normal cervical epithelial tissues

Project description:To explore the circRNA expression profiles during the development and progression of cervical cancer, we performed RNA sequencing analysis with ribosomal RNA-depleted in HPV negative normal cervical epithelium, HPV16 positive normal cervical epithelium, HPV16 positive high-grade squamous intraepithelial lesion (HSIL), and HPV16 positive cervical squamous cell carcinoma tissues,6 cases in each group.Totally 66868 circRNAs were identified (Back-spliced junctions reads≥1)

Differentially expressed gene profiles according to physical status of human papillomavirus integration in cervical cancer

Project description:Integration of human papillomavirus (HPV) DNA into the host genome is a critical aetiological event in the progression from normal cervix to intraepithelial neoplasm, and finally to invasive cervical cancer. In this study, we want to know how HPV DNA physical status relates to treatment outcome for cervical carcinomas. Cervical cancer samples were compared with normal sample. And also, we divided 39 cervical cancer patients into four groups according to HPV DNA physical status and investigated differentially expressed gene profiles in these groups using Agilent two-color experiment.

human plasma sample parallel reaction monitoring

Project description:Women are vulnerable to cervical diseases including normal control, HSIL and early stage cervical carcinoma . The parallel reaction monitoring mass spectrometry (PRM-MS) were used to qualitatively and quantitatively analyze the candidate differential proteins identified in our previous studies and to link them with HPV status. The integration of HPV status with candidate serum markers is expected to efficiently narrow down the high risk population and provide sufficient clinical information for early diagnosis and effective therapy.

MicroRNA analysis in HPV-positive and HPV-negative cervical cancer cell lines

Project description:Persistent infection by high-risk human papillomaviruses (HPVs) is associated with the development of cervical cancer and a subset of anogenital and head and neck squamous cell carcinomas. Abnormal expression of cellular microRNAs (miRNAs) plays an important role in the development of cancer, including HPV-related tumors. MiRNA expression profile was investigated by microrray analysis in the HPV-positive cervical cancer cell lines SiHa (HPV16-positive cell line derived from a cervical squamous cell carcinoma), CaSki (HPV16-positive cell line derived from a metastatic cervical epidermoid carcinoma), and HeLa (HPV18-positive cell line derived from a cervical adenocarcinoma) and compared with primary HFKs and C33a (HPV-negative cervical cell line).

Genome-wide microRNA profiling of HPV-positive self-samples: Promising triage markers for early detection of cervical cancer

Project description:Offering self-sampling for HPV testing improves the effectiveness of current cervical screening programs. Molecular triage markers directly applicable on self-samples are needed to further stratify HPV-positive women at risk of cervical cancer (so-called triage) and to avoid over-referral and overtreatment. MicroRNAs (miRNAs) deregulation has been implicated in the development of cervical cancer, and represents a potential class of triage markers. However, it is unknown whether deregulated miRNA expression is reflected in self-samples. This study is the first to establish genome-wide miRNA profiles in HPV-positive self-samples to identify miRNAs that can predict the presence of CIN3 and cervical cancer in self-samples. Small RNA sequencing (sRNA-Seq) was conducted to determine genome-wide miRNA expression profiles in 73 HPV-positive self-samples of women with and without cervical precancer (CIN3). The optimal miRNA marker panel for CIN3 detection was determined by GRidge, a penalized method on logistic regression. Classification of sRNA-Seq data yielded a panel of 9 miRNAs with a combined Area Under the Curve (AUC) of 0.89 for CIN3 detection. Six out of nine miRNAs were validated by qPCR in 165 independent HPV-positive self-samples and resulted in a combined AUC of 0.72 for CIN3+ detection. This study shows that deregulated miRNA expression associated with CIN3 and cervical cancer development can be detected in HPV-positive self-samples using genome-wide miRNA profiling. Further validation by qPCR indicates that miRNA expression analysis offers a promising novel molecular triage strategy for CIN3 and cervical cancer detection applicable to self-samples.
