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.

Study shows how pseudogenes can regulate activity of PTEN cancer-related gene

Small stretches of DNA in the human genome are known as "pseudogenes" because, while their sequences are nearly identical to those of various genes, they have long been thought to be non-coding "junk" DNA.

Researchers identify new pseudogene that regulates tumour-suppressing PTEN

Researchers at Karolinska Institutet in Sweden have identified a new so-called pseudogene that regulates the tumour-suppressing PTEN gene. They hope that this pseudogene will be able to control PTEN to reverse the tumour process, make the cancer tumour more sensitive to chemotherapy and to prevent the development of resistance.

Systemic delivery of antisense oligonucleotides neutralizes mutant RNA toxicity in mice with DM1

By targeting the specific mutation that causes the hereditary neuromuscular disease myotonic dystrophy, it is possible to neutralize the mutant RNA toxicity and minimize or even eliminate the disabling symptoms of the disease.

Study confirms presence of four molecular classes of head and neck squamous cell carcinoma

Head and neck squamous cell carcinoma (HNSCC) is the seventh most common form of cancer in the United States, but other than an association with the human papillomavirus, no validated molecular profile of the disease has been established.

Researchers identify new function for matriptase enzyme

Dr. Martin Richter (pharmacology), investigator with the Centre de recherche clinique Étienne-Le Bel (CRCELB) at the Centre hospitalier universitaire de Sherbrooke (CHUS) and professor in the Faculty of Medicine and Health Sciences of the Université de Sherbrooke (UdeS), and his collaborators have identified a new function of the enzyme matriptase, present in the human respiratory system, that can activate a viral protein involved in infections caused by the H1N1 influenza (or flu) virus.

Article provides examples of how epigenetic drug treatments could be beneficial in treating cancers

A review article by researchers at Boston University School of Medicine (BUSM) proposes a new epigenetic hypothesis linked to tumor production and novel ideas about what causes progenitor cells to develop into cancer cells. Published in the February 2013 issue of Epigenomics, the article provides examples of how epigenetic drug treatments could be beneficial in treating cancers while also decreasing the likelihood of cancer relapse.

Study may help design better DAA drug cocktails to treat HCV

Hepatitis C virus (HCV) infection affects about 4 million in the United States and is the primary cause of liver cirrhosis and liver cancer. Current therapy against HCV is suboptimal. Daclatasvir, a direct acting antiviral (DAA) agent in development for the treatment of HCV, targets one of the HCV proteins (i.e., NS5A) and causes the fastest viral decline (within 12 hours of treatment) ever seen with anti-HCV drugs.

Insights into HIV-1 virion makeup could improve gene therapy

A discovery about how the HIV-1 virion packages genomic RNA may help researchers to improve the efficacy of gene therapy.

Article details mechanism by which long non-coding RNA-activators promote gene expression

Long segments of RNA- encoded in our DNA but not translated into protein-are key to physically manipulating DNA in order to activate certain genes, say researchers at The Wistar Institute. These non-coding RNA-activators (ncRNA-a) have a crucial role in turning genes on and off during early embryonic development, researchers say, and have also been connected with diseases, including some cancers, in adults.

TSG might be novel compound for treatment of Alzheimer's and dementia with Lewy body

Administration of the active compound tetrahydroxystilbene glucoside (TSG) derived from the Chinese herbal medicine Polygonum multiflorum Thunb, reversed both overexpression of α-synuclein, a small protein found in the brain, and its accumulation using a mouse model of Alzheimer's disease.

New approach could make gene therapy dramatically more effective for HIV patients

A research team from Case Western Reserve University School of Medicine has discovered an approach that could make gene therapy dramatically more effective for patients.

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.
