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).

Study identifies DNA mutations linking liver disease with obesity and diabetes

For the first time, DNA mutations in liver cells have been identified that impact metabolism and insulin sensitivity in patients with liver disease.

Research elucidates how chaperones display "selective promiscuity" for specific proteins

A team of researchers at the University of Massachusetts Amherst has announced a major new advance in understanding how our genetic information eventually translates into functional proteins - one of the building blocks of human life.

Women who carry a mutation in PALB2 gene more likely to be diagnosed with breast cancer

Most of us have heard about the BRCA1 and BRCA2 genes. Men and women with a personal and/or family history of breast cancer have been offered testing for mutations in these two genes for a number of years to determine if they are at greater risk for breast and other cancers.

Single-genome sequencing reveals malaria parasite genetics and evolution

Understanding how malaria parasites evolve after a human is bitten by an infected mosquito is very difficult. There can be billions of individual parasites in a patient's bloodstream and traditional genetic sequencing techniques can't identify the raw material for evolution: new mutations.

Novel therapy approach could stop tumor growth

The immune system protects the body from cancer. To protect healthy body cells from its own immune system, they have developed a protective shield: the protein CD47 is a so called "don't eat me" signal, which tells the immune cells to stand back.

Scientists move a step closer to harnessing viruses to fight antibiotic resistance

As antibiotics increasingly develop resistance to bacteria that cause infection, scientists have moved a step closer to harnessing viruses as an alternative form of therapy.

CAST brings advancements in genomic medicine to admixed individuals

One way to make health care more personalized is to use a person's DNA sequence — or genome — to predict their risk of disease. But as the field of precision medicine grows, so have concerns that we may be leaving a large fraction of Americans out.

Nucleoside modifications suppress the potential of RNA to activate dendritic cells

A new paper shows that human TLR3, TLR7, and TLR8 receptors are activated with naturally occurring RNA, but this is eliminated once modified nucleosides such as m5C, m6A, m5U s2U, or pseudouridine are incorporated.

Development of disinfection process based on ozone for highly efficient inactivation of SARS-CoV-2

This study aimed to evaluate the ozone capacity generated within a newly developed disinfection chamber to eradicate SARS-CoV-2 from porous materials and non-porous materials like glass.

Research reveals components of Sinbis virus ribonucleoproteins

To address this gap in research regarding the understanding of post-replicative alphavirus RNPs, scientists have created a novel proteome-wide approach known as viral RNA interactome capture (vRIC). This study is available in the bioRxiv* preprint server while awaiting peer review.

CRISPR/Cas9-directed epigenetic editing reveals diverse transcriptomic regulation and functional effects

Oncotarget published "Diverse transcriptional regulation and functional effects revealed by CRISPR/Cas9-directed epigenetic editing" which reported that the adequate functioning of this process is indispensable for tissue homeostasis and cell fate determination.

New algorithm provides a high-definition analysis of genome organization in single cells

Within the microscopic boundaries of a single human cell, the intricate folds and arrangements of protein and DNA bundles dictate a person's fate: which genes are expressed, which are suppressed, and - importantly - whether they stay healthy or develop disease.

Plasmonic sensing of isothermally amplified nucleic acids and single-molecule detection of SARS-CoV-2

A new study finds that plasmonic sensing of LAMP amplicons through DNA hybridization enables highly specific detection of SARS-CoV-2 RNA.

CDC and ClinGen partner to develop expert curated variant list for the genomic community

The Centers for Disease Control and Prevention's Genetic Testing Reference Material Program (GeT-RM) has partnered with the Clinical Genome Resource (ClinGen) to develop a publicly available list of 546 expert curated pathogenic variants in 84 genes for use in next-generation sequencing (NGS) genetic testing.

Exosomal and non-exosomal miRNAs may serve as biomarkers for HCV-related cirrhosis, liver cancer

Oncotarget published "Exosomal and non-exosomal miRNA expression levels in patients with HCV-related cirrhosis and liver cancer" which reported that patients with HCV-related cirrhosis are at risk for liver cancer development.

Vaccine-induced memory B cells can recognize SARS-CoV-2 variants

Researchers have been investigating the effect that memory B cells produced in individuals who have received an mRNA vaccine have against SARS-CoV-2 variants.

New metagenome assembler can generate accurate DNA sequences

Metagenomics often involves sequencing DNA samples that can only be described as "tricky." Such DNA shows high heterogeneity, which can cause interspecies misassemblies.

Study traces the evolution of hepatitis B virus since prehistoric times

A study published in the journal Science traces the evolution of the hepatitis B virus from prehistory to the present, revealing dissemination routes and changes in viral diversity. Domingo Carlos Salazar García, researcher from the Prehistory, Archeology and Ancient History Department of the University of Valencia, has participated in this study led by the Max Planck Institute for the Science of Human History (Germany).

Penn State researchers sequence bacteria genomes to enhance the early detection of novel pathogens

To enhance the early detection of novel infectious bacteria that could cause outbreaks of infectious disease and public health emergencies, a team of researchers in Penn State's College of Agricultural Sciences will sequence the genomes of 700 Bacilli bacteria - near relatives of the biothreat pathogen that causes anthrax.
