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).

Using cationic nanonmaterials to target visceral adiposity

Researchers have long been working on how to treat obesity, a serious condition that can lead to hypertension, diabetes, chronic inflammation, and cardiovascular diseases.

New metagenomic study reveals global landscape of antimicrobial resistance

There are large geographical differences in both how frequently resistant genes occur and in which types of bacteria the genes are found.

Two experimental mRNA vaccines highly effective in reducing malaria infection and transmission

Malaria is found in more than 90 countries around the world, causing 241 million cases and an estimated 627,000 deaths every year.

Early life experiences can affect gene activity more than half a lifetime later

Early life experiences can impact the activity of our genes much later on and even affect longevity, finds a new study in fruit flies led by UCL researchers.

The importance of early cancer screening

In this interview, Thomas Qiu, Senior Product Manager from BGI Genomics, talks to NewsMedical about current global cancer rates, and the importance of early cancer screening.

INPP5D gene plays key role in enabling microglial cells to prevent plaque buildup

A change in the DNA code (mutation) of a gene that plays a key role in the brain's immune defenses may prevent related cells from clearing away protein-filled clumps, a new study in mice shows.

Understanding how the gut mycobiota respond to antibiotic treatment

Antibiotic treatment disrupts the balance of beneficial and harmful bacteria in a person's gut. That disruption can lead to the overgrowth of fungal species in the gut mycobiota, including the common intestinal yeast Candida albicans.

Scientists discover how an enzyme involved in DNA repair becomes vital to tumor survival

Scientists at the Francis Crick Institute, in collaboration with Artios, have identified how an enzyme involved in DNA repair (POLQ), becomes vital to the survival of certain cancers, if the cancer cells lose the ability to use a more common method of DNA repair.

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.
