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).

Researchers rejuvenate aged human cells with stem cell technology

Scientists have used stem cell technology to force old human cells to rejuvenate, reversing the impact that aging has on cells.

Old human cells regain youthful strength after rejuvenating protein treatment, study finds

Old human cells return to a more youthful and vigorous state after being induced to briefly express a panel of proteins involved in embryonic development, according to a new study by researchers at the Stanford University School of Medicine.

Crumpled grapheme can be more sensitive in detecting DNA cancer markers

Graphene-based biosensors could usher in an era of liquid biopsy, detecting DNA cancer markers circulating in a patient's blood or serum. But current designs need a lot of DNA.

3D chromatin landscapes in T cell acute lymphoblastic leukemia important beyond DNA code changes

Children with aggressive blood cancers have differences -- not just in the DNA code of their blood cells -- but also in the heavily twisted protein superstructure that controls access to genes.

Scientists discover new genetic editing powers in squid

Revealing yet another super-power in the skillful squid, scientists have discovered that squid massively edit their own genetic instructions not only within the nucleus of their neurons, but also within the axon -- the long, slender neural projections that transmit electrical impulses to other neurons.

Harnessing human genetics to uncover clues to longevity

The genetic code within DNA has long been thought to determine whether one becomes sick or resists illnesses. DNA contains the information that makes all cells that compose our bodies and allows them to function.

Microbiome search-based method can improve efficiency in disease detection and diagnosis

Big data makes big promises when it comes to providing insights into human behavior and health. The problem is how to harness the information it provides in an efficient manner.

Study identifies ancestral fragments of DNA associated with hereditary prostate cancer

Vanderbilt researchers have identified haplotypes, ancestral fragments of DNA, that are associated with hereditary prostate cancer (HPC) in a first-of-its-kind genomic study made possible by the study of prostate cancer patients with family histories of the disease.

Changes in 3D genetic structure equally important as DNA code mutations in childhood leukemia

A study found that children with aggressive blood cancers have different superstructures of the proteins that control gene access.

High blood pressure and obesity shown to be two strongest risk factors for shortening lifespan

A team have demonstrated that high blood pressure and obesity are the two strongest risk factors of shortening our lifespan.

Plasma monitoring of EGFR mutations in NSCLC may help predict resistance to tyrosine kinase inhibitors

Oncotarget Volume 11, Issue 11 reported that at clinical progression, 64 EGFR T790M plasma positive patients were subjected to second line-treatment with osimertinib and strictly monitored during the first month of therapy.

Researcher working to measure gene expression in blood of patients treated for opioid use disorder

MingKuan Lin, Research Assistant Professor, INOVA Neuroscience, School of Systems Biology, is working to measure gene expression levels in blood from patients undergoing treatment with buprenorphine for opioid use disorder.

Scientists identify new role of important factor in early embryonic development

In collaboration with Stanford University, a working group from MedUni Vienna’s Division of Cell and Developmental Biology, led by Mark Wossidlo, has identified the role of a factor involved in early embryonic development.

MILabs enhances preclinical diagnostic U-CT system for COVID-19 research

Based on recent scientific research, diagnostic X-ray CT is able to detect COVID-19, the disease caused by the novel coronavirus (SARS-CoV-2), in individuals with high clinical suspicion of the virus -- even in cases with negative initial DNA tests.

Researchers produce fat busting proteins in the lab

Triglycerides, those fats that seem to be the bane of any diet, remain a mystery for many researchers. Plenty of them are in Big Macs, deep pan pizza and the like, but some are a necessity to fuel the body for daily activities.

Diet affects sperm and the health of offspring

A new study published in the journal Molecular Cell, in March 2020, reports that parental diet is a crucial factor in the future metabolic health of the offspring.

The cost of excessive sugar in the diet

A new study from the MRC London Institute of Medical Sciences, in the UK, reports that while eating foods rich in sugar does not necessarily make you fat, they can make you very sick. They do this by increasing the level of a compound called uric acid in the blood. The study is published in the journal Cell Metabolism in March 2020.
