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.

Researchers discover SCANR that helps protect a cell's genes against DNA interlopers

Gene wars rage inside our cells, with invading DNA regularly threatening to subvert our human blueprint. Now, building on Nobel-Prize-winning findings, UC San Francisco researchers have discovered a molecular machine that helps protect a cell's genes against these DNA interlopers.

Nucleic Acid Therapeutics publishes special research section on noncoding RNAs

As scientists continue to unravel the complexity of the human genome and to uncover vital elements that play a role in both normal physiology and disease, one particular class of elements called noncoding RNAs is gaining a lot of attention. Guest Editor Tom Cech, PhD and Executive Editor Fintan Steele, PhD explore the enormous potential value of this rapidly advancing research area in their Editorial " The (Noncoding) RNA World."

Study shows importance of lncRNAs for regulation of adipogeneis

Whitehead Institute researchers have identified a previously unrecognized layer of genetic regulation that is necessary for the generation of undesirable white fat cells. When this regulation is disrupted, white fat cells are unable to accumulate lipid droplets or mature from their precursors.

FOXC2 vital to epithelial-mesenchymal transition in breast cancer

Researchers have identified a pivotal protein in a cellular transformation that makes a cancer cell more resistant to treatment and more capable of growing and spreading, making it an inviting new target for drug development.

CELF6 genetic mutation may underlie common behaviors seen in people with autism

Scientists at Washington University School of Medicine in St. Louis have identified a genetic mutation that may underlie common behaviors seen in some people with autism, such as difficulty communicating and resistance to change.

Ability to tune gene activity will permit refined research for drug resistance, cancer

Scientists who built a synthetic gene circuit that allowed for the precise tuning of a gene's expression in yeast have now refined this new research tool to work in human cells, according to research published online in Nature Communications.

New drug delivery system can reduce size of ovarian tumors by as much as 83%

By loading fragile RNA into silicon nanoparticles, researchers from The Methodist Hospital and two other institutions found a new drug delivery system can reduce the size of ovarian tumors by as much as 83 percent -- and stop tumor growth in chemotherapy-resistant ovarian cancer tissue.

RNAi effective in treating cancer patients

The new study published in Cancer Discovery, the flagship journal of the American Association of Cancer Research (AACR), involving three Spanish and six American research centres, presents significant results in treating cancer patients with nanoparticles containing ribonucleic acid interference (RNAi) molecules.

Metastatic renal cell carcinoma (mRCC) therapy: an interview with Charles A. Nicolette, Ph.D., CSO of Argos Therapeutics

Metastatic renal cell carcinoma is a devastating disease. There are roughly 20-25,000 new cases per year in the United States and it is increasing for some reason.

Study shows effects of maternal obesity on fetuses

In a study to be presented on February 15 between 8 a.m. and 10 a.m. PST, at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting -, in San Francisco, California, researchers from Tufts Medical Center will present findings showing the effects of maternal obesity on a fetus, specifically in the development of the brain.

Researchers identify miR-506 as potential therapeutic candidate for metastatic ovarian cancer

Researchers employed an extensive analysis of genomic information to identify a new, high-risk cohort of ovarian cancer patients, characterize their tumors, find a potential treatment and test it in mouse models of the disease.

Researchers discover miR-27b that regulates lipid levels in the blood

Researchers have identified a microRNA liver gene, miR-27b, which regulates lipid (cholesterol or fat) levels in the blood. This regulator gene controls multiple genes involved in dyslipidemia-abnormal blood cholesterol levels that can contribute to heart disease.

MicroRNA can be used to define four subtypes of triple-negative breast cancer

A new, large-scale study of triple-negative breast cancer shows that small molecules called microRNA can be used to define four subtypes of this aggressive malignancy.

UPC develops new system for electroporation of cell cultures

Researchers from the Polytechnic University of Catalonia have developed a technique that improves and cuts the cost of a technique called electroporation, which involves opening pores in cell membranes using an electric field to introduce substances like drugs and DNA. Current methods are aggressive and expensive whereas the new system manages to apply low voltage electroporation with a small printed circuit board, which costs less than a Euro per unit and does not damage cells.

CtBP may play a key role in aggressive forms of breast cancer

A protein associated with conditions of metabolic imbalance, such as diabetes and obesity, may play a role in the development of aggressive forms of breast cancer, according to new findings by researchers at the National Cancer Institute (NCI), part of the National Institutes of Health, and their colleagues.

Tumor necrosis factor receptor 2 involved in renal decline in diabetes

Researchers have found that circulating levels of tumor necrosis factor receptor 2 are independently associated with the development of chronic kidney disease in nonobese Japanese patients with Type 2 diabetes.

Investigators discover two new genes associated with severe early-onset disorders of heart rhythm

A team led by Vanderbilt University investigators has discovered two new genes - both coding for the signaling protein calmodulin - associated with severe early-onset disorders of heart rhythm.

Liver gene found to regulate cholesterol and fat blood levels

Researchers have identified a microRNA liver gene, miR-27b, which regulates lipid (cholesterol or fat) levels in the blood. This regulator gene controls multiple genes involved in dyslipidemia—abnormal blood cholesterol levels that can contribute to heart disease.

Researchers assess complete landscape of kinome expression in cancer

When it comes to gene sequencing and personalized medicine for cancer, spotting an aberrant kinase is a home run. The proteins are relatively easy to target with drugs and plenty of kinase inhibitors already exist.

Non-coding RNA MALAT1 influences lung cancer metastasis

The vast majority - approximately 80 percent - of our DNA does not code for proteins, yet it gets transcribed into RNA. These RNA molecules are called non-coding and fulfill multiple tasks in the cell. Alongside a well-studied group of small RNAs, there is also a class of so-called long non-coding RNAs consisting of more than 200 nucleotides.
