Error-prone DNA replication and repair may lead to mutations and cancer in individuals who inherit a mutant copy of the BRCA1 gene, according to a new study by Weill Cornell Medicine investigators.
DNA's 3D shape — its twisted ladders complexly curled into coils and loops — and other features beyond its genetic code may influence where "hotspots" of cancer-causing mutations accumulate. That's ...
An analysis of pre-treatment tumor specimens from 105 patients with localized muscle-invasive bladder cancer found that the presence of a mutation in any one of three genes, all known to be involved ...
From the time we are conceived and through old age, genetic mutations accumulate in all our tissues, eluding the body’s typically efficient DNA repair machinery and potentially affecting our health ...
While most known types of DNA damage are fixed by our cells’ in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows. This means that ...
Researchers discover unexpected patterns in mutation risks across individuals, uncovering 13 distinct genomic patterns. The study provides crucial insights into cancer evolution, identifying the genes ...
There are some genes that can promote cancer; they are sometimes called oncogenes, and in tumor cells, mutations are often found in these genes. When they are functioning normally, oncogenes are often ...
The gene p53 acts as a tumor suppressor and often is called the ‘guardian of the genome.’ This gene is central to maintaining genomic stability, which prevents mutations from accumulating and leading ...
Mutations are changes in the molecular "letters" that make up the DNA code, the blueprint for all living cells. Some of these changes can have little effect, but others can lead to diseases, including ...
Geneticists looking inside the nuclear genome for mutations that contribute to disease have long relied on a principal known as constraint modeling, which allows researchers to assess the degree of ...
