How does a begnihn tumor become cancerous?
While the evolution of cancer towards its most aggressive phases is largely studied, the mechanisms by which a benign tumour can become malignant remain poorly understood. Based on this observation, the "Nuclear Receptors and Prostate Diseases" team has developed a new model to study these early phases in Drosophila. Their work highlights the crucial role of growth factors in the transformation of the tumour. These results are published in Nature Communications (Rambur et al., 2020).

Muscular dystrophy and cardiac defects: the calcium lead
The majority of patients suffering from Myotonic Dystrophy Type I (DM1) exhibit cardiac conduction disturbance, reducing their life expectancy and causing sometimes sudden death. In their last study (Auxerre-Plantié et al., 2019), the team “Diversification of muscle and heart cells in normal and pathological conditions” used the fruitfly as a model system to reveal that this cardiac conduction defects are linked to gene expression alteration in cellular calcium regulation pathways, offering a new therapeutic lead for DM1 cardiac involvement.

Read moreTranscriptional alterations in Glioma: DNA methylation is the tip of the “epigenetic” iceberg
In cancer cells, aberrant DNA methylation is commonly associated with transcriptional alterations, including silencing of tumor suppressor genes. However, multiple epigenetic mechanisms, including polycomb repressive marks, contribute to gene deregulation in cancer. In its last study (Court et al., 2019) the team " Genomic Imprinting and the epigenetic control of cell fate determination" used glioma, one the most widespread type of brain tumor, to evaluate for the first time the relative contribution of DNA methylation-independent mechanisms on transcriptional alteration at CpG-island (CGI)/promoter-associated genes in cancer cells. They found that most transcriptional alterations in tumor samples were DNA methylation-independent. Instead, altered histone H3 trimethylation at lysine 27 (H3K27me3) was the predominant molecular defect at deregulated genes.
