Highlights
The most remarkable major achievements were focused on the deregulation of FAS/FASL pathway and in the contribution of JAK2 mutations to T-LBL development . Specifically, we have demonstrated that the FAS-FASL system is impaired in a significant fraction of lymphomas through inactivating mutations and/or deregulation of FAS and/or other members of the pathway rendering T-LBL tumour cells more resistant to apoptotic cell death . Regarding JAK2 we have identified one activating TEL- JAK2 translocation and six missense mutations, identifying intra-tumour heterogeneity (subclonal heterogeneity) with implications for targeted therapies and accurately diagnosis . Functional approaches revealed that several JAK2 mutations may activate JAK-STAT signalling pathway and to induce the expression of the potent oncogene LMO2 . Aberrant hypermethylation of SOCS3 also contributes to enhance activation of JAK-STAT signalling in these tumours . We therefore proposed that the use of pan-JAK inhibitors in combination with epigenetic drugs should be considered in future treatments . In addition our team has collaborated in the demonstration that the cannabinoid receptor CB2 is a pivotal regulator of HER2 oncogenic signalling in breast cancer; and in the identification of new susceptibility genes involved in alcohol use disorders .
With regard to projects, our team has participated in a European initiative (OPERRA-604984) (2014- 16) and in an ACCI-CIBERER-12-03 project; and directed several projects: (1) from the Spanish Nuclear Security Council; (2) the Spanish National Plan (SAF2012-36566); (3) and from the IIS-FJD .
Additional results were a doctoral thesis, our participation in one training course, and in several Masters and Post-graduates degrees at several Universities or Institutions (UAM, UCM, CNIO etc .) . Members employed by the CIBERER have participated in multiple training courses organized by the CIBERER itself or other Institutions from the del SNS . Finally, as a member of the IIS-FJD, our team have performed genetic and epigenetic analyses of all T-LBL samples attended in the FJD Hospital .
