Ribonucleic acid (RNA) is a biologically important type of molecule that consists of a long chain of nucleotide units. Each nucleotide consists of a nitrogenous base, a ribose sugar, and a phosphate.

Protein discovery could lead to mosquito "birth control"

Researchers have discovered a way of preventing mosquito eggs from hatching, paving the way for drugs that could serve as “birth control” within mosquito populations.

New mechanism of gene regulation involved in tumor progression discovered

Genes contain all the information needed for the functioning of cells, tissues, and organs in our body. Gene expression, meaning when and how are the genes being read and executed, is thoroughly regulated like an assembly line with several things happening one after another.

Study offers new insight on mechanism underlying control of gene expression

Researchers have provided new insight on the mechanism underlying the control of gene expression in all living organisms, according to a study published today in eLife.

New analytic method can precisely detect viral infections using immune responses

Cytomegalovirus is widespread and remains in the body for a lifetime after infection. In healthy individuals, this virus is usually kept in check but can become dangerous when the immune system is weakened or during pregnancy.

New molecular engineering method improves precision of biomarker analysis

Researchers from the University of Helsinki in cooperation with the University of Tartu, Competence Centre on Health Technologies from Estonia, and the Karolinska Institute, published an article in Nature's partner journal Genomic Medicine in which they present Targeted Allele Counting by sequencing along with several of its potential applications.

Research illuminates abilities of ADAR1 to ‘hyper-mutate’ tumor suppressor RNAs in leukemia

Writing in the January 3 issue of Cancer Cell, researchers at University of California San Diego School of Medicine report that detection of "copy editing" by a stem cell enzyme called ADAR1, which is active in more than 20 tumor types, may provide a kind of molecular radar for early detection of malignancies and represent a new therapeutic target for preventing cancer cell resistance to chemotherapy and radiation.

Researchers reveal cause of possible genetic problems in mitochondria

A group of researchers from the Andalusian Centre for Molecular Biology and Regenerative Medicine has revealed the importance of eliminating any excess of defective products that might have accumulated in the mitochondria, as its presence generates mitochondrial instability and information loss on the mitochondrial genome.

Study provides new insights into how genes are activated

In a study in Nature, researchers at Karolinska Institutet present a new method for analyzing how instructions in the genome control how our genes are activated in individual cells.

Himalayan marmot genome offers clues to high-altitude adaptation

Himalayan marmots can survive at altitudes up to 5,000 meters in the Himalayan regions of India, Nepal, and Pakistan and on the Qinghai-Tibetan Plateau of China, where many of them face extreme cold, little oxygen, and few other resources.

White colonies on kimchi surface is not formed by molds but by yeasts, finds study

WiKim reported that the white colonies on the surface of kimchi is not formed by molds but by "yeasts" and that genomic data was acquired regarding the hygienic safety of the yeast strains.

Yale researchers use arthritis medication to treat patient with disfiguring sarcoidosis

An all-Yale team of researchers successfully treated a patient with disfiguring sarcoidosis, a chronic disease that can affect multiple organs, with a drug approved for rheumatoid arthritis.

Study investigates role of miRNAs in anesthetic-induced myocardial conditioning

Many studies have shown that the mechanism of drug-induced myocardial conditioning is enzyme-mediated through messenger RNA and miRNA regulation. In this study Orriach et al. investigated the role that miRNAs play in the cardio-protective effect of halogenated anesthetics, which are widely used in cardiac surgery.

Elegant, low-cost approach enhances single-cell RNA sequencing

Droplet microfluidics has revolutionized single-cell RNA sequencing, offering a low-cost, high-throughput method for single-cell genomics. However, this method has been limited in its ability to capture complete RNA transcription information.

Study lays foundation for addressing unresolved questions in human aging

Doctors have long observed that biological age and chronological age are not always one and the same. A 55-year-old may exhibit many signs of old age and have numerous age-related diseases, whereas an 80-year-old may be healthy and robust.

Study uncovers initial folding mechanism of membrane proteins, key in design of new drugs

An international team coordinated by the Interdisciplinary Research Structure in Biotechnology and Biomedicine of the University of Valencia has proved how the folding of membrane proteins begins before they are inserted into biological membranes, a fact that has been central to the biochemical research for decades.
