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).

CRISPR gene-drive technology reverses antibiotic resistance in bacteria

Antibiotic resistance (AR) has steadily accelerated in recent years to become a global health crisis. As deadly bacteria evolve new ways to elude drug treatments for a variety of illnesses, a growing number of "superbugs" have emerged, ramping up estimates of more than 10 million worldwide deaths per year by 2050.

RNA micelles enable targeted chemotherapy without immune toxicity

A new study in mice hints at the potential to use tiny particles made with RNA molecules to deliver chemotherapy drugs and other therapies directly to tumors, killing cancer cells without generating an immune response or toxicity-related side effects.

Blocking p300 restores chemotherapy sensitivity in resistant tumors

Overcoming tumor resistance to chemotherapy drugs has long been a challenge for oncology clinicians and researchers.

European collaboration transforms immune cell data into cancer biomarkers

World Cancer Day, marked on 4 February, is an international day dedicated to raising awareness of cancer, and to encouraging its prevention, detection and treatment.

New DNA-based vaccine scaffolds boost targeted immune responses to HIV

One of the biggest hurdles in developing an HIV vaccine is coaxing the body to produce the right kind of immune cells and antibodies. In most vaccines, HIV proteins are attached to a larger protein scaffolding that mimics a virus.

Computational method clarifies microbial signals in tumor sequencing

When scientists sequence tumor DNA, they typically find small amounts of genetic code from bacteria, viruses and fungi – microorganisms that, if actually present in tumor tissues, could influence how they grow, evade immunity or respond to treatment.

Dyslexia linked to broader brain network vulnerabilities

A University of Houston psychology professor is challenging the notion that dyslexia, or specific reading disorder, stems from a single faulty gene in the brain, suggesting instead that it is caused by an overall brain network vulnerability.

New workflow boosts nuclear delivery for safer gene therapy

Gene therapy holds the promise of preventing and curing disease by manipulating gene expression within a patient's cells. However, to be effective, the new gene must make it into a cell's nucleus.

Next-generation sequencing expands possibilities for newborn screening

Every year, millions of newborns undergo routine screening as a preventive strategy to detect inherited disorders before symptoms emerge.

Too many antioxidants may negatively affect future offspring

Antioxidants have been marketed as miracle supplements, touted for preventing chronic diseases and cancers; treating COPD and dementia; and slowing aging.

DNA marker reveals pyrethroid resistance in malaria mosquitoes

A new study, jointly led by Liverpool School of Tropical Medicine and the Centre for Research in Infectious Diseases (CRID) in Cameroon, has detected a DNA marker in a gene encoding for a key enzyme, known as cytochrome P450, that helps mosquitoes to break down and survive exposure to pyrethroids, the main insecticides used for treating bed nets.

Five mutation patterns shape how cancers evade immunity

Cancer cells carry thousands of mutations, but not all mutations are created equal. Some make tumors highly visible to the immune system, while others help cancers hide.

Newly discovered stage controls malaria parasite division

Researchers studying the malaria parasite Plasmodium falciparum have discovered a previously unknown stage in its life cycle that appears to be crucial for reproduction.

New compound advances body clock independent of dosing time

A collaborative team including Emeritus Professor Tei H. (Kanazawa University), Associate Professor Takahata Y. (Osaka University), Professor Numano R. (Toyohashi University of Technology), and Associate Professor Uriu K. (Institute of Science Tokyo) discovered that Mic-628 selectively induces the mammalian clock gene Per1.
