MANY THANKS !
The 1st International Symposium "Immune Responses in Cancer and Infection" jointly organized by the CRCL and the CIRI (International Research Centre in Infectiology) took place recently in Lyon. It was a great pleaser to welcome 20 international speakers as well as a total of 380 participants! We thank our sponsors and partners which help us to organize this event! Many thanks again.

A stemness-related ZEB1-MSRB3 axis governs cellular pliancy and breast cancer genome stability

11 April 2017
Morel AP et al. Nature Medecine Avril 2017 (CRCL team of Alain Puisieux).
Chromosomal instability (CIN), a feature of most adult neoplasms from their early stages onward, is a driver of tumorigenesis. However, several malignancy subtypes, including some triple-negative breast cancers, display a paucity of genomic aberrations, thus suggesting that tumor development may occur in the absence of CIN. Here we show that the differentiation status of normal human mammary epithelial cells dictates cell behavior after an oncogenic event and predetermines the genetic routes toward malignancy. Whereas oncogene induction in differentiated cells induces massive DNA damage, mammary stem cells are resistant, owing to a preemptive program driven by the transcription factor ZEB1 and the methionine sulfoxide reductase MSRB3. The prevention of oncogene-induced DNA damage precludes induction of the oncosuppressive p53-dependent DNA-damage response, thereby increasing stem cells' intrinsic susceptibility to malignant transformation. In accord with this model, a subclass of breast neoplasms exhibit unique pathological features, including high ZEB1 expression, a low frequency of TP53 mutations and low CIN.

Structural Decoding of the Netrin-1/UNC5 Interaction and its Therapeutical Implications in Cancers

25 March 2016
This study involves the team of Patrick Mehlen.
Netrin-1 has been shown to be up-regulated in a fraction of human cancers as a mechanism to allow these tumors to escape the pro-apoptotic activity of some of its main dependence receptors, the UNC5 homologs (UNC5H). Here we identify the V-2 domain of netrin-1 to be important for its interaction with the Ig1/Ig2 domains of UNC5H2. We generate a humanized anti-netrin-1 antibody that disrupts the interaction between netrin-1 and UNC5H2 and triggers death of netrin-1-expressing tumor cells in vitro. We also present evidence that combining the anti-netrin-1 antibody with epidrugs such as decitabine could be effective in treating tumors showing no or modest netrin-1 expression. These results support that this antibody is a promising drug candidate.
