IMIM: The inhibition of a protein opens the door to the treatment of pancreatic cancer, one of the tumours with the worst prognosis

IMIM: The inhibition of a protein opens the door to the treatment of pancreatic cancer, one of the tumours with the worst prognosis


News from IMIM


Researchers from IMIM (Hospital del Mar Medical Research Institute) have identified a new protein, galectin-1, as a possible therapeutic target for pancreatic cancer. For the first time they have demonstrated the effects of the inhibition of this protein in mice suffering this type of cancer and the results showed an increase in survival of 20%. The work further suggests that it could be a therapeutic target with no adverse effects. This article will be published in the next edition of the Cancer Research journal, will be featured on the front page and will also be published as an author's view in OncoImmunology.

Until now, the strategies for treating this tumour were aimed at attacking the tumour cells and had little success. The latest studies indicate that trying to destroy what surrounds the tumour is possibly a better strategy. “Our contribution is directed toward this, as the reduction of galectin-1 mainly affects the immune system and the cells and structure that surrounds the tumour cells, which is called the stroma. Therefore, galectin-1 as a therapeutic target has great potential”, explains Dr. Pilar Navarro, co-ordinator of the research group on molecular mechanisms of tumorigenesis of IMIM and director of the research.
