Gene Expression News and Research

RSS

Gene Expression is the process by which a gene gets turned on in a cell to make RNA and proteins. Gene expression may be measured by looking at the RNA, or the protein made from the RNA, or what the protein does in a cell.

HDAC-mediated mechanisms play critical role in regulating lung repair and regeneration

Lung diseases such as asthma and chronic obstructive pulmonary disease (COPD) are on the rise, according to the American Lung Association and the National Institutes of Health.

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.

HIF-1α protein can work directly to stop new cells from forming

A protein known for turning on genes to help cells survive low-oxygen conditions also slows down the copying of new DNA strands, thus shutting down the growth of new cells, Johns Hopkins researchers report. Their discovery has wide-ranging implications, they say, given the importance of this copying - known as DNA replication - and new cell growth to many of the body's functions and in such diseases as cancer.

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.

Scientists explore development of unique dentition of 'toothed whales'

Whales are mammals, but they don't look like the mammals living around us, as they have a triangular fluke for tail, no hind legs and no body hair. And inside their mouths, their teeth are unfamiliar too - being much simpler and 'peg like'. A multidisciplinary team of researchers have now married together the fossil record and the embryonic development process to investigate how the whale got its teeth.

Real-time PCR reproducibility improved by handheld electronic pipette

INTEGRA has reported how a leading US clinical diagnostic laboratory has, using a VIAFLO 96 handheld electronic pipette, significantly improved the reproducibility and productivity with which it carries out Real-time PCR assays.

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.

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.

Castle Biosciences launches MyUvealMelanoma website

Castle Biosciences Inc., a leading developer of prognostic tests for rare cancers, announced today the launch of MyUvealMelanoma.com, a website created to educate newly diagnosed patients, their families and healthcare providers about the most common form of eye cancer. MyUvealMelanoma tells the story of this disease, its treatment and the importance of prognostic testing, through the experience of patients who recently faced this devastating diagnosis first-hand.

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.

Probiotics shows promise in reducing both incidence and severity of necrotizing enterocolitis

"Good" bacteria that live in our intestines have been linked with a variety of health benefits, from fighting disease to preventing obesity. In a new study, Kriston Ganguli of Massachusetts General Hospital for Children and Harvard Medical School and her colleagues have discovered another advantage to these friendly microscopic tenants: Chemicals secreted by good bacteria that typically live in the intestines of babies could reduce the frequency and severity of a common and often-lethal disease of premature infants.

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.

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.

RNF20 protein required for MLL-rearranged leukemia amplification

Acute myeloid leukemia (AML) is an aggressive blood cancer that is currently incurable in 70% of patients. In a bold effort, CSHL scientists are among those identifying and characterizing the molecular mechanisms responsible for this cancer in order to generate potential new therapeutics.

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.

Combined genomic and proteomic plasma analysis can identify molecular disease mechanisms

For the first time, scientists have combined genomic and proteomic analysis of blood plasma to enhance identification of genetically regulated protein traits. This could be applied to any large association study of civilization diseases where blood plasma has been collected, vastly improving a clinician's ability to identify disease susceptibility in individuals and populations.

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.
