Bioinformaticians at IMIM and UPF have used molecular simulation techniques to explain a specific step in the maturation of the HIV virions, essential in understanding how the virus replicates. These results, which have been published in the latest edition of PNAS, could be crucial to the design of future antiretrovirals.The work has been carried out using GPUGRID.net, a voluntary distributed computing platform leveraging GPU accelerators to deliver “virtual supercomputing” performance.

Exposure to dioxins during pregnancy is associated with endocrine-disrupting effects in male infants. Genitalia distances that normally are longer in males than females, were reduced among male newborns whose mothers had higher exposure to dioxins. This is revealed in a study of 700 pregnant women and newborns from Greece and Spain.

Intake of foods high in acrylamide during pregnancy is associated with lower birth weight and smaller head circumference. This was revealed in an international study of the diet of 1,100 pregnant women and newborns from Denmark, England, Greece, Norway and Spain in which IMIM has participated.

Patients with breast cancer that undergo a selective sentinel lymph node biopsy have a better quality of life 12 months after surgery than those submitted to lymph node dissection. "Until now, there was a slight controversy as to the benefits in terms of the quality of life of patients undergoing a sentinel lymph node biopsy compared to a lymph node dissection.” says Roser Belmonte, a doctor at the Department of Physical Medicine and Rehabilitation at Hospital del Mar-Esperança and a researcher at IMIM.

Researchers from IMIM, have succeeded in determining the function of a new variant of enzyme IKKalpha (IKKα) to activate some of the genes taking part in the tumor progressions of colorectal cancer. In the future, this fact will make it possible to design new drugs that inhibit this enzyme specifically and are less toxic for the remaining body cells, hence improving the treatment for this disease.

Researchers from IMIM have deciphered the function executed by a protein called ?-catenin in generating blood tissue stem cells. These cells, also called haematopoietic, are used as a source for transplants that form part of the therapies to fight different types of leukaemia. The results obtained will open the doors to produce these stem cells in the laboratory and, thus, improve the quality and quantity of these surgical procedures. This will let patients with no compatible donors be able to benefit from this discovery in the future.

Researchers at the IMIM (Institut de Recerca Hospital del Mar) have proven that the absence of the 14-3-3 protein sigma in breast cancer cells is directly associated with these cells’ capacity to activate the signalling of a protein complex called NF-kB, which is related to tumour progression. The activation of NF-kB in tumours was also identified as the best indicator for relapse in breast cancer patients, compared to other parameters currently used, such as the presence of affected ganglions or the tumour’s size and degree.

Researchers at the IMIM (Hospital del Mar Research Institute) and the Hospital del Mar have studied the role of NK cells in the development and progression of Chronic Obstructive Pulmonary Disease (COPD) when a viral infection is present. The results from the study show that these cells play a decisive role in the natural progression of the disease.

An international collaborative study with the participation of researchers from the IMIM (Hospital del Mar Research Institute), has studied whether the link between the levels of HDL cholesterol, commonly called “good cholesterol” and the risk of suffering an acute myocardial infarction is or isn’t causal, by using genetic biomarkers. The article will be published in the prestigious Lancet journal.

A group of researchers from the IMIM (Hospital del Mar Research Institute) and from the INAD (Hospital del Mar Neuropsychiatry and Addictions Institute) has participated in an international study aiming to give a general overview at a chemical, pharmacological and behavioural level of a recently appeared new chemical compound, according to the Recreational Drugs European Network, as a new abused drug: methoxetamine (MXE).
