New mechanism for repair of chromosomal breaks

Chromosomal breaks are the most harmful damage for cells. If they are not repaired, they block the duplication and segregation of chromosomes, stop the growth cycle and cause cell death. These breaks appear frequently in tumor cells and are produced spontaneously during the replication of genetic material.

Researchers identify involvement of certain cortical areas in the loss of control over food intake

Researchers at UPF, in collaboration with researchers from the University of Mainz (Germany), the Center for Genomic Regulation, Instituto Cajal, Johannes Gutenberg University (Germany), the Autonomous University Barcelona and Hospital del Mar have identified for the first time the involvement of certain cortical areas in the brain in the loss of control over food intake.

Study provides new insight into the regenerative capacity of mammalian embryos

A calf was born from an embryo lacking cells which form a large part of the placenta, providing new insight into the regenerative capacity of mammalian embryos.

New strategy uses iPSCs to regulate immune reaction to transplanted tissues

Scientists suggest a new strategy that uses induced pluripotent stem cells (iPSCs) to regulate immune reaction to transplanted tissues.

Fly model could help lay the foundation for new therapies to fight 'difficult' pathogen

The Clostridium difficile pathogen takes its name from the French word for "difficult." A bacterium that is known to cause symptoms ranging from diarrhea to life-threatening colon damage, C. difficile is part of a growing epidemic of concern for the elderly and patients on antibiotics.

Research provides new insights into molecular basis of X-chromosome inactivation

Researchers at the European Molecular Biology Laboratory in Heidelberg and Institut Curie in Paris have shown that the protein SPEN plays a crucial role in the process of X-chromosome inactivation, whereby female mammalian embryos silence gene expression on one of their two X chromosomes.

Defining neurogenic niche proteome helps identify key regulators of neurogenesis

In mammalian adult brains, neural stem cells are only present in few specific parts, so called niches. Only these niches are capable of generating new neurons.

Collaborative research uncovers underlying rules that, when broken, contribute to ALS

Clumps of proteins inside cells are a common thread in many neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS) or Lou Gehrig's disease.

Researchers reveal new activity above the surface in brain-cell receptors

Like buoys bobbing on the ocean, many receptors float on the surface of a cell's membrane with a part sticking above the water and another underwater, inside the cell's cytoplasm.

Genetic fingerprints could help identify cancer-causing culprits

Causes of cancer are being cataloged through an international study revealing the genetic fingerprints of DNA-damaging processes that drive cancer development.

Study lays foundation for translating mitochondrial biology into clinical applications

A study led by The University of Texas MD Anderson Cancer Center furthered understanding about mitochondria, the cell components known as the "powerhouse of the cell." Knowing more about the genome is crucial given that mitochondria play important roles in tumorigenesis.

Researchers discover new mutational phenomenon chromothripsis in cancer

Researchers at Harvard Medical School and EMBL-EBI have carried out the largest analysis across cancer types of the newly discovered mutational phenomenon chromothripsis.

Analyzing cancer-specific alterations found in tumor's RNA

Researchers at EMBL-EBI were among the leaders of a large international consortium that carried out a joint analysis of data from over 1000 donors of more than 25 cancer types, studying data on their whole genomes along with tumor transcriptome data, which indicates the genes that are active within a tumor.

Researchers study how structural variations in the genome can lead to cancer

Structural variations in genomes can arise from deleting, amplifying, or reordering genomic segments ranging from a few thousand letters of the genetic code to whole chromosomes.

First comprehensive survey of viruses found within different cancers

Researchers from the University of East Anglia have helped to carry out the first comprehensive survey of viruses found within different types of cancer.

Researchers discover new genetic drivers of cancer

The discovery of genetic drivers of cancer can have critical implications for the diagnosis and treatment of cancer patients, yet genome analysis has focused primarily on only 1-2% of the whole genome - the part that contains the code for making proteins.
