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).

Nanotechnology plays major role in COVID-19 vaccine development

From mRNA vaccines entering clinical trials, to peptide-based vaccines and using molecular farming to scale vaccine production, the COVID-19 pandemic is pushing new and emerging nanotechnologies into the frontlines and the headlines.

Genetic variation shapes individual perception of fatty foods, twins study reveals

Most people would agree that the pleasure of some foods stems in part from its fat content. New research, led by the Monell Chemical Senses Center, has now found that liking of fatty food is more complex than its fat content alone - it could also be related to inborn genetic traits of the consumer related to fat perception.

People with accelerated biological age at increased risk of COVID-19 symptom severity and mortality

Now, a new study published on the preprint server medRxiv in July 2020 discusses the explanation in terms of the biological aging markers in patients with severe disease, rather than the chronological age.

Baylor Scott & White Research Institute receives NIH award for esophageal cancer study

The incidence of esophageal adenocarcinoma has increased 8-fold over the past 50 years. This is one of the deadliest cancers, with a five-year survival rate of only 20 percent. However, the survival rate more than doubles if the cancer is identified early.

Newly identified gene variants in Black Americans could lead to precision prostate cancer therapies

Black men in the United States are known to suffer disproportionately from prostate cancer, but few studies have investigated whether genetic differences in prostate tumors could have anything to do with these health disparities.

Upcoming phase II study to discover personalized therapy for patients at high risk for breast cancer relapse

Indiana University School of Medicine researchers Milan Radovich, PhD, and Bryan Schneider, MD, have discovered that the presence of circulating tumor DNA (ctDNA) and circulating tumor cells (CTCs) in the plasma of women's blood who have undergone chemotherapy prior to surgery for the treatment of stage 1, 2 or 3 triple negative breast cancer are critical indicators for the prediction of disease recurrence and disease-free survival.

UHN leads first-of-its-kind real world evidence study of medical cannabis

Medical cannabis is finally being put under the microscope, in a first-of-its-kind real world evidence study led by Dr. Hance Clarke, Director of Pain Services, Toronto General Hospital, and a recognized leader in educating Canadians about chronic pain management and the risk factors of continued opioid use.

Mapping immune landscape of hematological malignancies may help improve cancer therapies

Activating the immune system of the body is a promising form of treatment for cancer. Researchers at the University of Helsinki and Helsinki University Hospital as well as the University of Eastern Finland mapped out the immune landscape of hematological malignancies in a dataset covering more than 10,000 patients to identify drug targets and patient groups which could potentially benefit from immunotherapies.

DNA hypermethylation correlated with reduced amygdala volume in male patients with schizophrenia

Researchers at Kumamoto University, Japan have revealed that DNA methylation occurs in the gene that codes serotonin transporter (SERT), a protein that regulates neurotransmitter transmission, in schizophrenia and bipolar patients.

Researchers identify factor that regulates the abnormal growth of heart

The human heart is like a sponge, able to expand and grow, increasing its capacity to take up blood. In theory, an enlarged heart can also squeeze out more blood, with more power, than an average-sized heart. But in reality, for most people, this growth - known as cardiac hypertrophy - is abnormal and signals trouble.
