Researchers at IRB Barcelona unravel a role for tumour suppressor genes in restricting the growth of neighbouring cell populations.
The study, published yesterday in PLoS Biology, might have implications for understanding the early events of tumorigenesis and the selection of the tumour-initiating cells.
The study, published in Current Biology, focuses on cilia, the cellular structures that by sensing chemicals and mechanical forces allow for smelling, hearing, and many other essential functions.
Researchers at IRB Barcelona reveal that the protein E-Cadherin is required for groups of diverse cells to migrate together
Tumours with intermediary levels of E-Cadherin generally have a poorer prognosis; the phenomenon of heterogeneous cell migration may be related to this
Researchers at IRB Barcelona discover the molecular mechanism that determines how epigenetic markers influence gene expression
Combination of two strong denaturants of DNA leads to stabilization of the structure
An unexpected finding that opens new fields to the biotechnological use of DNA
A study, published today in the journal Nature, marks a milestone in the understanding of chronic lymphocytic leukemia (CLL)
CLL is the most frequent leukemia with more than 12,000 new cases diagnosed in Europe every year
IRB Barcelona group leader Modesto Orozco participated in the study as he is involved with the International Cancer Genome Consortium (ICGC)
Maria Macias, Pau Martín, and Joan Massagué publish a featured review article in Trends in Biochemical Sciences (TIBS) on the Smad protein family, the members of which play a key role in cancer.
The article is accompanied by a web application in which available 3D structures of Smads can be explored, as can their alterations in several metazoa, their variability in humans, and their mutations in tumours.
Researchers at IRB Barcelona study CEP63, a gene that is mutated in Seckel Syndrome, a rare disease that causes microcephaly and growth defects.
The protein CEP63 is crucial for the correct division of brain stem cells. In its absence, mice reproduce Seckel Syndrome.
The scientists rescued the microcephaly during mouse embryonic development by removing a protein that caused the loss of stem cells.
Also, CEP63-depleted male mice are infertile. The relationship between this protein and sperm production is revealed for the first time.
A study done on fruit flies and published in Nature Communications reveals that the protein dDsk2, in addition to degrading proteins, also plays a key role in regulating gene expression.
This protein is also present in humans and is known to be mutated in several neurodegenerative diseases, including Alzheimer’s. But the mechanism by which these mutations contribute to the development of disease remains unclear.
IRB Barcelona is to start a study to examine the relationship between dDsk2 mutations and neurodegenerative diseases.
dSysMap (which stands for “Disease-mutations Systemic Mapping”) is a computational tool to interpret the effect of genetic mutations on the development of complex diseases.
The tool allows researchers to explore how alterations in more than 2,000 proteins affect the diverse biological functions in which these molecules are involved.
The Pan-Cancer consortium has included the tool in order to gain a more global view of the causes of tumour development.
