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).

One round of adenosine triphosphate turnover sufficient for SNARE complex disassembly

In 2013, James E. Rothman, Randy W. Schekman, and Thomas C. Südhof won the Nobel Prize in Physiology or Medicine for their discoveries of molecular machineries for vesicle trafficking, a major transport system in cells for maintaining cellular processes. Vesicle traffic acts as a kind of "home-delivery service" in cells.

MDC scientists find solution to increase efficiency of precise genetic modifications

CRISPR-Cas9 is a powerful new tool for editing the genome. For researchers around the world, the CRISPR-Cas9 technique is an exciting innovation because it is faster and cheaper than previous methods. Now, using a molecular trick, Dr. Van Trung Chu and Professor Klaus Rajewsky of the Max Delbrück Center for Molecular Medicine Berlin-Buch and Dr. Ralf Kühn, MDC and Berlin Institute of Health, have found a solution to considerably increase the efficiency of precise genetic modifications by up to eightfold.

Researchers harness gene editing technique in mosquito that infects people with deadly diseases

Traditionally, to understand how a gene functions, a scientist would breed an organism that lacks that gene - "knocking it out" - then ask how the organism has changed. Are its senses affected? Its behavior?

Research: Common bacteria poised to become antibiotic-resistant superbugs

Antibiotic resistance is poised to spread globally among bacteria frequently implicated in respiratory and urinary infections in hospital settings, according to new research at Washington University School of Medicine in St. Louis.

Study: Blood test may help diagnose Fragile X syndrome related disorders in women

A blood test may shed new light on Fragile X syndrome related disorders in women, according to a new study published in the March 25, 2015, online issue of Neurology, the medical journal of the American Academy of Neurology. Fragile X is the most common inherited form of intellectual disability and the most frequent genetic cause of autism.

Mitochondrial DNA movement: an interview with Professor Jiri Neuzil, Griffith University

According to our understanding, mitochondria undergo cycles of fusion-fission, i.e. they divide within the constraints of a cell and, upon cell division, each of the two daughter cells gets its ‘share’ of mitochondria.

LifeCodexx announces promising results from proof-of-principle study of qPCR-based NIPT assay

LifeCodexx AG today reports the successful outcome of a proof-of-principle of its novel assay for non-invasive prenatal testing (NIPT assay) based on quantitative real-time PCR (qPCR). This NIPT assay, designed to determine fetal aneuploidies from maternal blood, will offer significant advantages, such as enhanced test performance at affordable prices, over other prenatal examination methods.

New study reveals how cells sort out loops meant to encode microRNAs

Just as two DNA strands naturally arrange themselves into a helix, DNA's molecular cousin RNA can form hairpin-like loops. But unlike DNA, which has a single job, RNA can play many parts -- including acting as a precursor for small molecules that block the activity of genes. These small RNA molecules must be trimmed from long hairpin-loop structures, raising a question: How do cells know which RNA loops need to be processed this way and which don't?

Markovian models show promise for describing postoperative pain trajectories

Markovian models show promise for describing postoperative pain states and, eventually, may help guide clinical decisions, a new study found.

DNA samples collected from tampons may help detect endometrial cancer

Researchers at Mayo Clinic have shown that it is possible to detect endometrial cancer using tumor DNA picked up by ordinary tampons. The new approach specifically examines DNA samples from vaginal secretions for the presence of chemical "off" switches — known as methylation — that can disable genes that normally keep cancer in check.

Brain-somatic-activating mutations in MTOR cause focal cortical dysplasia type II

Epilepsy is a brain disorder that afflicts more than 50 million people worldwide. Many epilepsy patients can control their symptoms through medication, but about 30% suffer from intractable epilepsy and are unable to manage the disease with drugs. Intractable epilepsy causes multiple seizures, permanent mental, physical, and developmental disabilities, and even death.
