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).

How does the KLF4 transcription factor influence gene expression?

Scientists have led a research group to identify a mechanism using which transcription factor KLF4 can influence gene expression.

Researchers develop a DNA sensor to target and detect infectious viruses in minutes

A new sensor can detect not only whether a virus is present, but whether it's infectious – an important distinction for containing viral spread.

Prions may help yeast cope with rapidly changing environmental conditions

Prions are proteins found in the brain and familiar for their role in causing disease.

Genetic and epigenetic origin of pediatric liver cancer uncovered

Researchers at Hiroshima University have analyzed the molecular findings of almost 160 pediatric liver cancer cases and discovered molecular markers that should help to understand and treat the considerable variation in prognoses.

Premature aging of the tracheobronchial stem cells could contribute to chronic lung disease

Are prematurely aged or overworked stem cells a significant factor in chronic lung disease? Findings of a study just released in STEM CELLS Translational Medicine (SCTM) say this is likely so.

Researchers seek to point a way toward a unified theory for DNA folding

At more than 2 meters long, the human DNA molecule uses intricate folding patterns to fit into cells while locally unfolding to express genes. Such phenomena, however, are difficult to measure in experiments, and theoretical frameworks explaining them continue to be at odds with one another.

Coral reef biodiversity shuffles rather than the predicted collapse under ocean warming, acidification

Coral reefs are among the most biologically diverse, complex and productive ecosystems on the planet. Most of coral reef biodiversity consists of tiny organisms living deep within the three-dimensional reef matrix.

Scientists find two proteins that pair up to build lifelines to cancer cells

In human cancer cell and mouse studies, researchers from Johns Hopkins Medicine have found that a set of proteins work in tandem to build supply lines that deliver oxygen and nutrients to tumors, enabling them to survive and grow.

Changes in epigenome responsible for reduced stem cell function upon aging

The bones become thinner with age, resulting in frequent fractures and making them susceptible to bone diseases like osteoporosis.

UC Riverside scientists aim to turn edible plants into mRNA vaccine factories

The future of vaccines may look more like eating a salad than getting a shot in the arm. UC Riverside scientists are studying whether they can turn edible plants like lettuce into mRNA vaccine factories.

Study opens new avenues for therapies against Charcot-Marie-Tooth disease

CMT, a rare hereditary condition, commences when genetic changes interrupt the transmission of nerve signals from the brain to the muscles of the extremities, specifically those of the lower limbs.

Researchers reveal why nerve cell’s protein production slows down in CMT patients

A team led by MDC researcher Marina Chekulaeva has figured out why protein production slows down in the nerve cells of people suffering from Charcot-Marie-Tooth disease. This discovery could lead to a new therapeutic approach, the scientists report in the journal "Nucleic Acids Research".

Programmable DNA-based microfluidic chip for performing complex mathematical calculations

The term 'DNA' immediately calls to mind the double-stranded helix that contains all our genetic information. But the individual units of its two strands are pairs of molecules bonded with each other in a selective, complementary fashion.
