Our main interest is the investigation of the molecular mechanisms underlying the progression of chronic liver disorders. We have identified one carbon metabolism (1CM) as an essential process to preserve the differentiated phenotype of quiescent hepatocytes. 1CM is a master connection between the intermediate metabolism and epigenetic regulation that must be finely tuned since its unbalance triggers a progressive liver ailment leading to Non Alcoholic Steatohepatitis (NASH) and Hepatocellular Carcinoma (HCC). Our work has contributed to elucidate protein networks that explain the molecular pathogenesis of chronic liver diseases and HCC using a functional proteomics approach. Deficiencies on key 1CM enzymes, such as methionine adenosyltransferase (MAT1A) and methylthioadenosine phosphorylase (MTAP) lead to a deregulated methylation capacity of liver cells and a deep reshape of their protein methylation profile (including RNA binding proteins). Assuming the key role of 1CM remodeling in the progression of liver disorders, we have developed a multiplexed mass spectrometry-based method to quantify the enzymes catalyzing 1CM reactions. This quantification kit is a straightforward method to follow up chronic liver diseased patients. All these studies are part of the Liver initiative of the Biology and Disease Human Proteome Project, which are currently coordinated by our lab. We are also actively participating in the functional annotation of unknown proteins in the framework of the Chromosome Centric Human Proteome Project. Our research has been founded with grants for more than 20 years and our results have been published in more than 140 peer reviewed scientific articles.

In the event that the cookies are installed from a computer or domain managed by the editor itself but the information collected by these is managed by a third party can not be considered as party cookies.

2. Types of cookies as the length of time that remain active:

Depending on the length of time that remain active in the terminal equipment can be distinguished:

- Session cookies: cookies are a type designed to collect and store data while the user accesses a web page. Are usually used to store information that only worth preserving for the service requested by the user at any one time (eg a list of products purchased).

- Persistent cookies: cookies are a type of data which are stored in the terminal and can be accessed and treated for a period defined by the head of the cookie, and can range from a few minutes to several years.

3. Cookies types according to their purpose:

Depending on the purpose for which the data are processed through cookies, we can distinguish between:

- Technical cookies: these are those that allow the user to navigate through a web page or application platform and the use of different options or services it exist as, for example, control traffic and data communication, identify the session, access to restricted access parts, remember the elements of an order, make the buying process an order, make an application for registration or participation in an event, use security features while browsing store content for dissemination videos or sound or share content via social networks.

- Customization cookies: these are those that allow the user to access the service with some general characteristics based on a predefined set of criteria in the user terminal would eg language, the type of browser through which you access the service, the locale from which you access the service, etc.
