What is the most important protein of the genome?
Several media, including Quo Magazine, have echoed the research headed by Ferran Azorín, CSIC research professor and group leader of the Chromatin Structure and Function laboratory at IRB Barcelona. The study reveals why histone 1 is a major protection factor against genomic instability and a vital protein for the organism.
Published in Nature Communications, this work explains for the first time that the suppression of histone 1 causes cell damage and genomic instability (DNA damage).

More than 200 regions (amino acids) in histones are identified as responsible for regulating the response to cell stress.
The study reports that histones undergo distinct modifications depending on the type of cell stress.
The work by the Cell Signaling laboratory has been published in the journal Nucleic Acids Research.
The newspapers Público and El Punt Avui,and the TV channel La Sexta, among other media, have reported on a recent study headed by Cayetano González, ICREA researcher at IRB Barcelona. Using the vinegar fly, Drosophila melanogaster, this study has identified possible regulators of the differences in tumours associated with the sex of an individual. Published in Science Advances, the study compares the brain tumours of male and female flies at the molecular level and identifies the protein responsible for the different degrees of aggressiveness.
An understanding of the molecular basis of differences in the incidence and survival of cancer between men and women may allow the discovery of specific and more effective treatments.
The study, published in Science Advances, compares the brain tumours of male and female flies at the molecular level and identifies proteins responsible for the different degree of aggressiveness.
