In this regard, they have discovered a scenario where the level of autophagy is much higher in cells with several copies of DNA and that it can even trigger this programmed cell death.

Nebreda, Dr. Maria J. Macias and Dr. Modesto Orozco, all at IRB Barcelona, has developed a new type of p38 inhibitor, which preferentially impairs one of the activation pathways of this protein. In particular, these inhibitors block the self-activation (or autophosphorylation) of p38 but allow it to continue to be activated by other mechanisms.

As essential structures with specialized functions, these organelles rely on intricate connections for seamless communication. Among these organelles, mitochondria (known as cell powerhouses) and the endoplasmic reticulum (responsible for protein and lipid synthesis) engage in vital exchanges.

The study, which was led by Dr. Guiomar Solanas, Dr. Salvador Aznar Benitah, both at IRB Barcelona, ​​and Dr. Holger Heyn, at CNAG, highlights an IL-17-mediated ageing process to an inflammatory state.

By reading their DNA letters, cells produce an intermediate RNA molecule that will give rise to the corresponding protein. Most diseases occur with altered protein levels, which are either a cause or consequence of the condition itself. RNA plays a pivotal role in diseases with altered protein levels by serving as the intermediary messenger between DNA and protein. Institute for Research in Biomedicine Barcelona
