\t\t\tThe protein p38 is a member of the MAPK family\u2014molecules that transmit signals from outside the cell inside, thus allowing an appropriate and dynamic cell response. This protein is expressed in all cells of the body and it performs highly diverse functions depending on the context and tissue involved. <\/p>\n

Nebreda’s group at IRB focuses on the function of p38 in cancer. Their work describes the essential role of p38 in tumour progression for the first time in vivo. Furthermore, the scientists demonstrate that the treatment of mice with a p38 inhibitor previously used in clinical assays causes a considerable reduction in tumour size. The study provides useful information for clinicians and pharmaceutical companies about the role of p38 in the context of colon cancer. Colorectal cancer is now the second leading cause of cancer-related death in the world. <\/p>\n

“p38 inhibitors may have clinical applications, but probably\u2014and this forms part of the medicine of the future\u2014these will be in combination with other drugs. We are trying to find out what p38 inhibitors should be combined with to make the tumour, which is now smaller, finally disappear,” explains the Spanish scientist Nebreda, head of the Signalling and Cell Cycle Lab at IRB, BBVA Foundation Cancer Research Professor and ICREA research professor. <\/p>\n

The role of p38 in cancer is not clear cut. In this same study, Indian-born Jalaj Gupta who recently obtained his PhD in Nebreda’s lab and is first author of the work, demonstrates that this same protein in a pre-tumoral context, favoured by inflammation of the colon\u2014also known as colitis\u2014impedes tumour development. <\/p>\n

It is well-known that patients with chronic inflammation of the intestine, such as that caused by Crohn’s disease, have a greater incidence of colon tumours that the healthy population. In order to study the relationship between inflammation and cancer, Nebreda’s team use mouse models that reproduce this inflammatory context. <\/p>\n
