DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

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.

New insight into genomic alterations associated with telomere maintenance mechanisms in cancer

To gain an infinite lifespan, cancer cells need to maintain the ends of their chromosomes, known as telomeres. They achieve this in various different ways.

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.

UMass Amherst study aims to develop new test for BRCA-positive lactating moms

Breastfeeding women with a pathogenic BRCA1 or BRCA2 genetic mutation face a significant risk, even at a young age, of breast and ovarian cancer.

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.

Age-linked cognitive decline could be slowed by immune activation

A new study published in February 2020 in the Journal of Experimental Medicine (JEM), reports that activating a specific type of immune cell found in the brain could delay reduced cognition often found in older people, and even prevent neurologic degeneration of age.

Research could help understand the effect of ionizing radiation on human cells

Small organic molecules, including the amino acids that form the 'building blocks' of proteins in living cells, fragment to form ions under the impact of high-energy radiation such as electron beams.

Targeting a protein could be key to suppressing breast cancer metastasis

A new study by University of Kentucky Markey Cancer Center researchers suggests that targeting a protein known as heat shock protein 47 (Hsp47) could be key for suppressing breast cancer metastasis.

Analysis shows overall survival in lung cancer patients harboring 'niche' mutations

Mutations were observed in all genes studied, except c-MET, DDR2, MAP2K1, and RET.

Princeton researchers find link between microbes and cancers in threatened California foxes

Can staph microbes lead to cancer? Microbes are known to affect digestion, mood and overall health, and now Princeton researchers have shown that a shift in the microbiome is linked to cancer -- at least in a threatened subspecies of foxes found only on one island off the California coast.

4D-printed microneedle array could replace painful hypodermic needles

Painful hypodermic needles may not be needed in the future to give shots, inject drugs and get blood samples.

Prenatal single cell blood test for gene defects

With the current state of knowledge regarding genetic testing, non-invasive prenatal testing (NIPT) is in favor for genetic testing in unborn babies, using fragments of DNA circulating in the mother’s blood.

Unveiling the structure of the influenza virus

The flu season is coming, and the frigid temperatures make it worse. The influenza B virus is the causative agent of the common flu, but over the past years, it has become more potent in causing disease. Now, a team of MIT scientists has found and unveiled the structure of the virus, particularly the key influenza protein, in the hopes to develop new drugs to combat influenza.

Study uncovers more pieces of the autism puzzle

A major international study from the Autism Sequencing Consortium with participation of researchers from the Danish iPSYCH psychiatry project, has recently mapped 102 new autism genes.

Developing tests for genetic signs could lead to earlier cancer detection

Early signs of cancer can appear years before diagnosis and developing tests for these genetic signs could provide new ways to spot cancer early, according to new research led by the Crick and EMBL-EBI, and supported by an international cancer genomics consortium, the Pan-Cancer Analysis of Whole Genomes Project.
