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).

Research finds higher rate of rare tandem repeats in the genomes of individuals with schizophrenia

In our cells, the language of DNA is written, making each of us unique. A tandem repeat occurs in DNA when a pattern of one or more nucleotides – the basic structural unit of DNA coded in the base of chemicals cytosine (C), adenine (A), guanine (G) and thymine (T) – is repeated multiple times in tandem. An example might be: CAG CAG CAG, in which the pattern CAG is repeated three times.

New evidence of mpox virus transmission before onset of symptoms

Researchers extensively followed-up high-risk contacts of clade IIb mpox (MPX) virus (MPXV)-infected patients to evaluate the risk of MPX after MPXV exposure and to characterize early MPXV infections.

CSU engineers introduce a better way to perform mosquito-tracking for disease applications

West Nile, Zika, dengue and malaria are all diseases spread by bites from infected mosquitoes. To track the threat of such diseases over large populations, scientists need to know where the mosquitoes are, where they've been, and where they might go.

Study identifies risk factors that increase Black men's susceptibility to early-onset prostate cancer

A family history of cancer and genetic variants that might be inherited appear to be important risk factors for Black men diagnosed with early-onset prostate cancer, a study involving Duke Health researchers has found.

Blood tests may be able to guide treatment discussions for patients with metastatic cancer

As cancers grow and potentially spread to new parts of the body, they often shed cells and DNA into the blood stream. DNA can be analyzed for both the amount of DNA present and whether any potential mutations exist that may aid providers in deciding on treatments.

AI tool can reliably classify difficult-to-diagnose nasal cavity tumors

Although tumors in the nasal cavity and the paranasal sinus are confined to a small space, they encompass a very broad spectrum with many tumor types.

What genes are associated with asthma exacerbations?

In a new study, researchers reviewed the genomics, transcriptomics, and epigenetics of asthma exacerbations (AEs).

Scientists report new target to combat coronary artery disease

Soon after cholesterol and fat start depositing on the lining of the blood vessels that supply your heart, the smooth muscle cells that give the blood vessels strength and flexibility start to get bigger and multiply.

How does quinoa affect the gut microbiome of men?

Although a high intake of whole grain foods reduces the risk of cardiometabolic diseases, obesity, type 2 diabetes, and certain types of cancers, the underlying mechanism behind this occurrence is unclear. Whole grain foods tend to be healthier due to their high dietary fiber and phytoconstituents, typically lost during refining.

Could mRNA vaccines triumph over other viral infections in humans and domestic animals?

Researchers review potential areas for mRNA vaccine development against pathogenic viruses other than SARS-CoV-2.

Isolated monoclonal antibodies targeting SARS-CoV-2 S1/S2 cleavage effective against Delta and Omicron

Isolated monoclonal antibodies neutralize SARS-CoV-2 Delta and Omicron variants.

Simultaneous radiation and immunotherapy can benefit mNSCLC patients with high tumor aneuploidy

In many cancer types, cancer cells try to survive by escaping attack from the immune system. These cancer cells hijack mechanisms called immune checkpoints to trick the immune system into thinking they are healthy cells.

Researchers highlight the importance of localizing BRCA gene mutations for better ovarian cancer treatment

Mutations of BRCA1 and BRCA2 genes, which are inherited by 1 in 400 and 1 in 800 people respectively, significantly increase the risk of certain cancers such as ovarian, breast, pancreatic and prostate cancer.

Two studies emphasize the need for ethnically diverse prostate cancer genetic testing

More than 1.4 million men were diagnosed with prostate cancer in 2020 globally, but the molecular characteristics of the disease remain unexplored for the majority of patients around the world.

Possibility of the first fluid biomarker that reflects brain pathology in primary tauopathies

Addressing this gap in research, a recent Nature Medicine study hypothesized that 4R isoform-specific MTBR-tau species accumulate in the patient’s brain of specific subtypes of 4R tauopathies.

Common chemotherapy drug could carry toxic inheritance for future generations of cancer survivors

A common chemotherapy drug could carry a toxic inheritance for children and grandchildren of adolescent cancer survivors, Washington State University-led research indicates.

Researchers discover a new function of CRISPR/Cas9 gene scissors

For several years now, the CRISPR/Cas9 gene scissors have been causing a sensation in science and medicine.

New CRISPR-based tool can snip out faulty genes and replace them with new ones

Building on the CRISPR gene-editing system, MIT researchers have designed a new tool that can snip out faulty genes and replace them with new ones, in a safer and more efficient way.

AI helps design synthetic DNA that controls cells' protein production

With the help of an AI, researchers at Chalmers University of Technology, Sweden, have succeeded in designing synthetic DNA that controls the cells' protein production.

Duke researchers find human DNA sequence divergence after split from common ancestor of chimpanzees

A team of Duke researchers has identified a group of human DNA sequences driving changes in brain development, digestion and immunity that seem to have evolved rapidly after our family line split from that of the chimpanzees, but before we split with the Neanderthals.
