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).

UVA Health researchers develop new tool to advance genomics and disease research

UVA Health researchers have developed an important new tool to help scientists sort signal from noise as they probe the genetic causes of cancer and other diseases.

Discovery could lead to new mantle cell lymphoma drugs

A form of blood cancer known as mantle cell lymphoma is critically dependent on a protein that coordinates gene expression, such that blocking its activity with an experimental drug dramatically slows the growth of this lymphoma in preclinical tests, according to a study from Weill Cornell Medicine researchers.

Microniches of intratumoral microbiota impact spatial and cellular heterogeneity in cancer

Researchers mapped spatial, cellular, and molecular interactions of host and tumor-associated bacteria within the tumor microenvironment.

Time-restricted eating may benefit Alzheimer's

In a recent study published in the Experimental Gerontology journal, researchers in the United States assessed the impact of time-restricted eating (TRE) on Alzheimer's disease (AD), cognitive decline, and sleep.

New studies improve understanding of the genetic factors that protect people against COVID-19

Two recent papers by Brazilian researchers have contributed to the scientific understanding of the genetic factors that protect people against infection by SARS-CoV-2 or prevent progression to severe COVID-19.

KEMEPHY diet may be an effective dietary pattern for athletes

Scientists have characterized the effects of the ketogenic Mediterranean diet with phytoextracts on gut microbiota composition in athletes. The study by researchers in Italy and Spain is published in the journal Frontiers in Nutrition.

Repetitive stress induces features of accelerated aging in the eye

New research from the University of California, Irvine, suggests aging is an important component of retinal ganglion cell death in glaucoma, and that novel pathways can be targeted when designing new treatments for glaucoma patients.

Researchers investigate the impact of cultural and genetic structure on food choices

Genetic studies of the past 20 years have extensively shown how, across human populations worldwide, the majority of genetic differences are encountered at the individual rather than at the population level.

Evaluating cell-free DNA-based blood tests for early detection of multiple cancers

Researchers assessed several approaches for a circulating cell-free deoxyribonucleic acid (cfDNA)-based multi-cancer early detection (MCED) test. Defining the clinical limit of detection (LOD) based on circulating tumor allele fraction (cTAF) enables the comparison of different approaches.

MIT researchers develop new technique for genome-wide studies of the liver

The liver’s ability to regenerate itself is legendary. Even if more than 70 percent of the organ is removed, the remaining tissue can regrow an entire new liver.

The role of bacteria in cancer growth

Tumor-associated microbiota is an important component of the tumor microenvironment (TME) across 33 types of human cancer. However, little evidence is available regarding the spatial distribution and localization of these microbes in tumor cells.

Rutgers scientists develop new approach to effectively shut down viral infections

Rutgers scientists have developed a new approach to stopping viral infections: a so-called live-attenuated, replication-defective DNA virus vaccine that uses a compound known as centanamycin to generate an altered virus for vaccine development.

New AI blood testing technology detects more than 80% of liver cancers

A novel artificial intelligence blood testing technology developed and used by Johns Hopkins Kimmel Cancer Center researchers to successfully detect lung cancer in a 2021 study has now detected more than 80% of liver cancers in a new study of 724 people.

Bombali ebolavirus has been detected among bats in Mozambique

Researchers reported on the detection of Bombali virus (BOMV, of the ebolavirus genus) ribonucleic acid (RNA) among three free-tailed Mops condylurus (Molossidae) bat species in Mozambique.

Pt(IV)-conjugated drug-delivery system shows efficacy in glioblastoma therapy

A recent study demonstrated a novel method for delivering anti-cancer drugs, conjugated to modified cell-penetrating peptides across the blood-brain barrier, in mice to treat glioblastoma.

Scientific gathering aims to integrate advances in cancer and aging research

Institute for Research in Biomedicine - IRB Ageing is the main risk factor for the development of cancer, and the features shared by these two biological processes are increasingly evident. This week the Institute for Research in Biomedicine (IRB Barcelona) and the BBVA Foundation are holding the 38th Barcelona Biomed conference "Quantitative dynamics of aging and premalignancy". Held at the Sant Pau Art Nouveau Site on 14, 15 and 16 November, the event will be hosting 21 internationally recognized experts in the field who will present their latest breakthroughs.
