简要总结
Human papilloma virus (HPV) is responsible of the most common sexually transmitted infection. It can cause severe cancer lesions, of the cervix, vulva, vagina, penis and oropharynx. The International Agency for Cancer Research of World Health Organization (WHO) classified a dozen of HPV related high-risk cancer types, and recognized cervical cancer as the most common HPV-related disease. HPV 16 and 18 are responsible for 70% of cervical cancers.
Due to the few symptoms of cervical cancer, women are often diagnosed with advanced state. Current treatments imply cervical conisation or hysterectomy, with or without lymphadenectomy and or radiotherapy, or chemotherapy.
However, few pharmacological options are available against oncogenic papilloma viruses and thus against recurrences The aim of this project is to develop relevant organoids models from patient biopsies that will be used to identify biomarkers and evaluate in a closest preclinical setting novel nucleic acids based therapeutic strategy for HPV-cervical-vaginal dysplasia and cancers.
详细描述
In this project, the investigators want to develop organotypic culture of primary-derived biopsies, and combine them with organ-on-a-chip technology, to better characterize the HPV infection and cancer progression, as well as to screen innovative treatments for cervical and vaginal cancers.
Our study will cover cervical dysplasia and cervical cancers HPV induced. The investigators will perform cervical and or vaginal biopsies from patients with oncogenic HPV lesions. A protocol validated to collect biopsies from precancerous cervico-vaginal lesions or cervical cancer patients in CHRO (Orleans, France). The biopsies will be performed during a consultation in the Hospital center of Orleans, or in the theatre room during a conisation or an hysterectomy. The PRIMMO platform is the research platform of Regional hospital center of Orleans (CHRO) dedicated to the promotion of translational research. It will be involved in the collection, analysis and biobank storage setup of the project. Fresh samples will be collected and bring directly to the lab for organoid cell culture development. Detection of HPV in each biopsy will be carried out by the PRIMMO platform.
The organoid development from patient biopsies will take place into the lab of the Biophysic Molecular center in Orleans.
The organoids will be selected according to three criteria: their ability to grow until a first passage, their doubling time and their ability to be frozen and resuscitated. Such organoids maintain pathogen-host interaction and better model physiopathology of vaginal cervical dysplasia CIN2-3 or cervical cancer and thus allow for the detection of biomarkers for pre-cancerous lesions. In addition, organoids reduce the use of animal models and can be used for drug screening, In a second step, the investigators propose to use mRNA to produce in situ the nanobodies targeting E6 and E7, to inhibit viral replication and tumor growth
Socio-epidemiological data will be collected for each patient, in the form of a table.
