Adenine News and Research

RSS

Adenine is one of the four bases in DNA that make up the letters ATGC, adenine is the "A". The others are guanine, cytosine, and thymine. Adenine always pairs with thymine.

Bottom up assembly of cells into 3-D microtissues

Scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory can now control how cells connect with one another in vitro and assemble themselves into three-dimensional, multicellular microtissues.

Discovery of gene variant for cleft lip

About 20 percent of isolated cleft lip, one of the world's most common birth defects, may be due to a one-letter difference in the DNA sequence of a gene involved in facial development, researchers supported by the National Institutes of Health report.

Potential method for repairing misspelling in DNA code that causes spinal muscular atrophy

Researchers at the University of Delaware have discovered a novel technique - that acts like a "spell-checker" for correcting a misspelling in the DNA code - to repair the defective gene that causes spinal muscular atrophy (SMA).

New understanding of cancer initiation

Researchers at the University of Nebraska Medical Center (UNMC) in Omaha have assisted in a significant discovery - the understanding of a common mechanism of cancer initiation - that could result in better cancer assessment, prevention and detection.

Discovery of gene variant that raises autism risk

Scientists have found a variation in a gene that may raise the risk of developing autism, especially when the variant is inherited from mothers rather than fathers.

Huntington's disease problem starts early

The damaging effects of the mutated protein involved in Huntington's disease take place earlier in cell life than previously believed, said researchers from Baylor College of Medicine in Houston in a report that appears in the current edition of the journal Neuron.

Gene variation increases risk of liver tumor in patients with cirrhosis

A particular gene variation appears to significantly increase the risk that individuals with cirrhosis of the liver will go on to develop hepatocellular carcinoma (HCC), a liver tumor that is the third leading cause of cancer death.

Advances in drug screening

With the discovery of suitable molecular targets - cellular molecules along pathways crucial for sustaining the life of cancer cells - comes the perplexing dilemma of where to find the next therapeutics that will bind to and disable those targets.

Research shows how stem cells decide to become either skeletal or smooth muscle

Researchers have discovered a key protein that controls how stem cells "choose" to become either skeletal muscle cells that move limbs, or smooth muscle cells that support blood vessels, according to a study published in the Proceedings of the National Academy of Sciences (PNAS).
