New study challenges longstanding assumption about the cause of the genome's most common mutation

A Ludwig Cancer Research study has punctured a longstanding assumption about the source of the most common type of DNA mutation seen in the genome—one that contributes to many genetic diseases, including cancer.

Study uncovers mutations and DNA structures driving bladder cancer

How bladder cancer originates and progresses has been illuminated as never before in a study led by researchers at Weill Cornell Medicine and the New York Genome Center. The researchers found that antiviral enzymes that mutate ...

Genetics

Study finds new genetic loci associated with dementia

A research team comprising several researchers within the University of Kentucky's Sanders-Brown Center on Aging has investigated the genetic risk of neuropathological traits commonly seen by neuropathologists performing ...

Genetics

How diabetes risk genes make cells less resilient to stress

The cells in your pancreas, like people, can only handle so much stress before they start to break down. Certain stressors, such as inflammation and high blood sugar, contribute to the development of type 2 diabetes by overwhelming ...

Cell line models identify cause of melanoma with drug resistance

Melanoma is a type of cancer that originates from melanocytes, the cells responsible for producing skin pigment, and is known as the most lethal form of skin cancer due to its high rates of metastasis and recurrence. With ...

Genetics

Algorithms uncover cancers' hidden genetic losses and gains

Understanding the specific mutations that contribute to different forms of cancer is critical to improving diagnosis and treatment. But limitations in DNA sequencing technology make it difficult to detect some major mutations ...

Genetics

New cause of syndromic microcephaly identified

Greenwood Genetic Center (GGC) researchers, in collaboration with scientists from Belgium, Spain, and Italy, have confirmed that variants in LMNB1 cause syndromic microcephaly with variable short stature, intellectual disability, ...

Genetics

Risk gene for Alzheimer's has early effects on the brain

A genetic predisposition to late-onset Alzheimer's disease affects how the brains of young adults cope with certain memory tasks. Researchers from the German Center for Neurodegenerative Diseases (DZNE) and the Ruhr-Universität ...

Decoding the genetics that drive disease

From Alzheimer's to obesity, life can change dramatically if you discover you have a genetic risk of disease. Now, a new study from the Australian Centre for Precision Health, University of South Australia is challenging ...

Genetics

DNA webs may drive lung pathology in severe COVID-19

Sticky webs of DNA released from immune cells known as neutrophils may cause much of the tissue damage associated with severe COVID-19 infections, according to two new studies published September 14 in the Journal of Experimental ...

Genetics

Taste buds may play role in fostering obesity in offspring

Cornell food scientists show in animal studies that a mother's high-fat diet may lead to more sweet-taste receptors and a greater attraction to unhealthy food in their offspring—resulting in poor feeding behavior, obesity ...

Studying the human genome to understand the risk of autism

A team of researchers at CHU Sainte-Justine and Université de Montréal has succeeded in using bioinformatics to develop a statistical model to assess how the gain or loss of genetic material impacts the risk of autism.

Genetics

Building blocks for microbiome research

All multicellular living beings are colonized by an unimaginably large number of microorganisms and have evolved together with these microbial symbionts from the beginning. The natural microbiome, i.e. the entirety of the ...

Telomere length varies across human tissue types

Telomere length has long been considered an important biomarker in human aging and disease, but most studies on the relationship between telomere length and health have looked only in a single tissue type: blood. This limitation ...

Genetics

Biological sex affects genes for body fat, cancer, birth weight

Biological sex has a small but ubiquitous influence on gene expression in almost every type of human tissue, reports a new study from Northwestern Medicine, the University of Chicago and the Centre for Genomic Regulation ...

Genetics

New genetic analysis method could advance personal genomics

Geneticists could identify the causes of disorders that currently go undiagnosed if standard practices for collecting individual genetic information were expanded to capture more variants that researchers can now decipher, ...
