In simple terms: a mutation is a stable change in genetic sequence that can be copied when cells or viruses replicate. Most mutations have no detectable effect, some contribute to disease, and a small ...

About 25% of lung adenocarcinomas have mutations of the gene KRAS, which drives uncontrolled cell growth. In recent years, ...

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 ...

Myeloid leukemias are among the most aggressive blood cancers and have low survival rates. Today, leukemia patients undergo genetic analysis to identify mutations and select the most appropriate ...

A new study of 450 colorectal cancer patients has delivered some of the clearest evidence yet that mutations in two DNA proofreading genes, POLE and POLD1, can identify which patients are most likely ...

Every time a cell divides, its chromosomes must be distributed correctly between the two daughter cells. Central to this ...

A study demonstrates that the 'previous state' of blood stem cells plays a decisive role in the subtype of leukemia that develops. The new technique, called STRACK, allows monitoring of the evolution ...

Researchers at the Institute for Bioengineering of Catalonia (IBEC) have produced a mutational map showing how mutations in amylin—a hormone that plays a key role in glucose regulation—affect its ...

A study led by the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC), working in collaboration with an international research team, has identified a new molecular mechanism ...

Bones are not simply the rigid scaffolding that holds a body upright; they are living organs whose construction is choreographed by an intricate web of genetic instructions. When even a single letter ...
