Examples of questions from
 Est-ce que les Coronavirus peuvent causer des cancers ?
 Est-ce qu’ils font partie de la famille des virus oncogènes ?
 Quelles sont les séquelles des infections SARS CoV 1 et 2, et MERS ?
 Est-ce que les épidémies SARS-Cov1 et MERS sont liées à des apparitions de cancers ?
 Est-ce que les lésions causées par l’infection SARS CoV2 peuvent potentialiser une
transformation tumorale? (évolution tissulaire et sensibilité au développement de cancers
suite à une fibrose, ou autres lésions)
 Quelles sont les voies de signalisation intracellulaires activées par les coronavirus ? Pendant
l’inflammation ? Quelles sont les adaptations métaboliques ?
 Est-ce qu’il y a des similitudes avec des virus oncogènes déjà connus tels que HPV, HBV, EBV,
etc. ? …
