The protein CPEB4, which coordinates the expression of hundreds of genes required for neuronal activity, is altered in the brains of individuals with autism

Published in Nature, the study indicates that a defect in CPEB4 could be the link between environmental factors that alter brain development and the genes that determine susceptibility to autism

  • A group of scientists headed by Maria Macias, ICREA researcher at IRB Barcelona, describes the mechanism through which TGIF1 inhibits the activity of Smad proteins.
  • The study, which used molecular and structural biology techniques to analyse this interaction, has been published in Nucleic Acids.

Published in Science Advances, the study shows that the TLK1 and TLK2 enzymes are critical for ensuring the copying of DNA.

Loss of TLK1 and TLK2 results in extensive DNA damage during DNA replication and in cancer cell death.

Depletion of TLK1/2 enhances the effectiveness of some chemotherapeutic agents currently being tested in clinical trials

A new computational model has allowed researchers to identify new therapeutic targets that can attack cancer cells by lowering their intracellular pH.

The study, which is the result of collaboration between IRB Barcelona, the Moffitt Cancer Center, and the University of Maryland, has been published in Nature Communications.

A team headed by Manuel Serrano at IRB Barcelona has designed a drug encapsulation system that selectively targets senescent cells.

The study paves the way for therapeutic approaches to eliminate senescent cells in many diseases, such as pulmonary fibrosis and cancer.

An international team led by computational biologist Fran Supek at IRB Barcelona develop a machine learning method to predict unknown gene functions of microbes.

The system examines and compares ‘big data’ available on the metagenomes of human and environmental microbiomes.

A new study by researchers at IRB Barcelona demonstrates that myeloid cells, which belong to the leucocyte family and form part of the innate immune system, use p38 protein signalling to support inflammation-associated colon cancer.

Published in EMBO Molecular Medicine, the study by Angel R. Nebreda suggests that inhibition of the p38 pathway in myeloid cells may be a useful therapeutic approach, especially in tumours associated with chronic inflammation.

Researchers at the Centre for Genomic Regulation (CRG) in collaboration with IRB Barcelona, developed a new method to systematically identify genes contributing to heritable cancer risk.

The study, published in Nature Communications, is a success story for data sharing and openness in science.

A new study in collaboration with the Genomic Instability and Cancer Laboratory at IRB Barcelona and led by the University of Copenhagen,  reveals that TLK2 displays lower levels of activity in intellectual disability and that it is possible to inhibit it in breast cancer, where it is overactive.

The study suggests that the enzyme may be a target for potential therapies.

Researchers at IRB Barcelona reveal that the protein NEK7 is relevant for the correct formation of neurons in the hippocampus, a region of the brain associated with memory.

Animals without NEK7 may also have defects in other other brain regions.
