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).

Phenols in purple corn may fight obesity, inflammation and diabetes, mice study shows

Scientists at the University of Illinois have developed new hybrids of purple corn containing different combinations of phytochemicals that may fight obesity, inflammation and diabetes, a new study in mice indicates.

CRISPR-scanning could lead to more effective treatments for cancer

11,000 people are predicted to die from acute myeloid leukemia in 2019, according to the American Cancer Society. The cancer starts in the bone marrow. There, mutated genes fail to prevent blood cells from replicating again and again and again, growing tumors.

Spatial orgnization of the genome can be altered using small molecules

Researchers have discovered that the spatial organization of the genome can be altered using small molecule compounds which are considered as promising anti-cancer drugs.

New catalog of DNA mutation 'fingerprints' could help doctors pinpoint cancer culprits

Scientists in Cambridge and London have developed a catalog of DNA mutation 'fingerprints' that could help doctors pinpoint the environmental culprit responsible for a patient's tumor - including showing some of the fingerprints left in lung tumors by specific chemicals found in tobacco smoke.

Restoring function of 'misregulated' cancer-fighting genes

Working with human colon cancer cells and mice, researchers led by experts at the Johns Hopkins Kimmel Cancer Center say they have successfully blocked the activity of portions of a protein known as UHRF1 and restored the function of hundreds of cancer-fighting genes that became "misregulated" by the disease.

Potential new therapeutic approach identified for neuroblastoma tumors

Research led by Michael Lan, PhD, Professor of Pediatrics and Genetics at LSU Health New Orleans School of Medicine, found that a compound named 5'-iodotubercidin (5'-IT) suppresses the growth of neuroblastoma cells and identified a potential new therapeutic approach for the disease.

Research group develops extremely sensitive pancreatic cancer diagnostic method

Thus, the prospects for early pancreatic cancer detection are of enormous importance. Innovation Fund Denmark has just granted 13.1 million kroner for new and promising pancreatic cancer diagnostic technologies.

Johns Hopkins scientists design new cell model of aging-associated colon cancer risk

Johns Hopkins Kimmel Cancer Center researchers say a new study of clusters of mouse cells known as "organoids" has significantly strengthened evidence that epigenetic changes, common to aging, play a essential role in colon cancer initiation.

DNA fragments from ancient hominins reveal new branches of the Denisovan lineage

It's widely accepted that anatomically modern humans interbred with their close relatives, the Neanderthals and Denisovans, as they dispersed out of Africa.

NASA Twins Study: Extended spaceflight has small, transient effect on the gut microbiome

A year in space seems to have a small but significant, transient effect on the gut microbiome, according to a new paper on the NASA Twins Study published in the journal Science.

High levels of blood lipids may worsen multiple sclerosis symptoms in obese patients

A newly published paper in the Lancet journal EBioMedicine identifies a link between high levels of blood lipids and worsening of disease in multiple sclerosis patients who are overweight or obese.

Modern humans interbred with multiple Denisovan populations, suggests study

The findings are based on a new study led by Murray Cox from Massey University in New Zealand and made possible by sampling efforts led by Herawati Sudoyo from the Eijkman Institute for Molecular Biology in Jakarta, Indonesia.

Study describes vulnerability shared by large subset of cancer cell lines

Cancer cells adapt to potentially fatal mutations and other molecular malfunctions by adjusting one or more other genes' activity, in the process becoming dependent on those genes for their survival and growth.

Rare gut condition is more predictable from individual's genetic makeup, study finds

Hirschsprung disease - a rare condition where the failure of gut nerves to develop before birth leads to impaired bowel contractions that prevent infants from passing stool - is more predictable from an individual's genetic makeup than previously envisioned.

Bacteria share genes with one another, even across tissue boundaries

Bacteria in the human body are sharing genes with one another at a higher rate than is typically seen in nature, and some of those genes appear to be traveling - independent of their microbial hosts - from one part of the body to another, researchers report in the journal Scientific Reports.

New liquid biopsy technique used to assess melanoma progression

When the surgeon surgically removes a melanoma, some patients are said to be 'cancer-free' and they do not get additional treatment. However, should the fluid obtained in the drainage implanted after surgery be tested using the liquid biopsy technique rather than be disposed of as medical waste, the test might predict the high or low risk of cancer recurrence.
