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).

Scientists discover major regulator of schizophrenia that is active during early development

Researchers have discovered a gene that acts as a master regulator of schizophrenia during the early stages of human brain development.

Simple genetic test may boost response rates in children with eosinophilic esophagitis

Personalized medicine - where the proper medicine and proper dose are used for the individual patient - moved a step closer to reality for children suffering from eosinophilic esophagitis, an inflammation of the food pipe often caused by an allergic reaction to certain foods.

Study identifies inhibitor that protects cells from toxic DUX4 effects

About one in 8,000 people have facioscapulohumeral muscular dystrophy, according to a 2014 study, which is relatively common in the world of genetic diseases.

New liquid biopsy test may be more predictive of patient's immunotherapy response

A new liquid biopsy test could detect microsatellite instability (MSI) and tumor mutational burden (TMB), indicating that it could help determine which patients are likely to respond to immune checkpoint inhibitors.

Gene coding error likely responsible for rare form of inherited 'short telomere' disease

By combing through the entire genetic sequences of a person with a lung scarring disease and 13 of the person’s relatives, Johns Hopkins Medicine researchers say they have found a coding error in a single gene that is likely responsible for a rare form of the disease and the abnormally short protective DNA caps on chromosomes long associated with it.

Novel technology makes biopsies less invasive and more informative

A team of researchers from the National University of Singapore has developed a novel technology that could sensitively and accurately detect and classify cancer cells, as well as determine the disease aggressiveness from the least invasive biopsies.

Long-term antibiotic use in preemies promotes drug-resistant gut bacteria

Very preterm infants are often sick and require antibiotic treatment to save their lives. However, when this form of therapy lasts for 20 months or more, it may affect the gut microbiome over the long-term in addition to its acute effects.

Gut microbiome and IBD – the connection maybe in diet says study

A new study has shown conclusive evidence that inflammatory bowel disease or IBD is intimately associated with the gut microbial environment which can be altered with prescription diet. The microbiome within the human gut is a collection of healthy and helpful bacteria that help in several functions of the body including development and maintenance of immunity.

Nanocapsules packed with gene-editing tools could be promising platform for many gene therapies

New tools for editing genetic code offer hope for new treatments for inherited diseases, some cancers, and even stubborn viral infections. But the typical method for delivering gene therapies to specific tissues in the body can be complicated and may cause troubling side effects.

Liquid biopsies provide complete picture of genetic alterations linked to cancer drug resistance

Many patients see their tumors shrink in response to a drug, only to have them come back with a vengeance as they evolve to fend off the treatment. Oncologists want to be able to quickly detect cancer drug resistance as it emerges in their patients and identify another drug the tumors will still respond to.

Mutations linked with sensitivity or resistance to immunotherapy in mNSCLC

The relationship between gene alterations and response to anti-PD-L1 with and without anti-CTLA-4 are not well characterized.

Salk researchers develop method to reveal epigenetic features of brain cells

The brain's prefrontal cortex, which gives us our ability to solve problems and plan ahead, contains billions of cells. But understanding the large diversity of cell types in this critical region, each with unique genetic and molecular properties, has been challenging.

Lung-MAP study: Majority of cancer patients don't understand genomic test results

A majority of cancer patients don't understand key aspects of the genomic test results they receive as participants in biomarker-driven clinical trials, according to a first-of-its-kind pilot study conducted under the Lung Cancer Master Protocol.

Researchers develop new cocktail of drugs that shrink pancreatic tumors

Cancer is relentless and resilient. When a drug blocks a cancer cell's main survival pathway, the cell avoids the obstacle by taking different pathways or detours to save itself. This tactic is called "developing resistance," and it's one of the key challenges researchers face when seeking effective therapeutics to combat pancreatic ductal adenocarcinoma (PDA).
