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.

Study indicates that smoking disrupts circadian clock function in both lungs and brain

As if cancer, heart disease and other diseases were not enough motivation to make quitting smoking your New Year's resolution, here's another wake-up call: New research published in the January 2014 issue of The FASEB Journal suggests that smoking disrupts the circadian clock function in both the lungs and the brain.

University of Utah discovers cellular mechanism that stops metastasis of breast cancer

Researchers from Huntsman Cancer Institute (HCI) at the University of Utah discovered a cellular mechanism that drives the spread of breast cancer to other parts of the body (metastasis), as well as a therapy which blocks that mechanism. The research results were published online in the journal Cell Reports on January 2.

Computer algorithm developed to identify genes that could be transformed to stop aging process

Restricting calorie consumption is one of the few proven ways to combat aging. Though the underlying mechanism is unknown, calorie restriction has been shown to prolong lifespan in yeast, worms, flies, monkeys, and, in some studies, humans.

Researchers study health consequences of RTE proliferation that occurs in aging tissues

The genomes of organisms from humans to corn are replete with "parasitic" strands of DNA that, when not suppressed, copy themselves and spread throughout the genome, potentially affecting health. Earlier this year Brown University researchers found that these "retrotransposable elements" were increasingly able to break free of the genome's control in cultures of human cells.

Researchers complete genomic analysis of cervical cancer in two patient populations

Researchers from the Boston area, Mexico, and Norway have completed a comprehensive genomic analysis of cervical cancer in two patient populations. The study identified recurrent genetic mutations not previously found in cervical cancer, including at least one for which targeted treatments have been approved for other forms of cancer.

Fluidigm announces universal sample prep workflow for single-cell DNA sequencing

Fluidigm Corporation today announced a universal sample prep workflow for single-cell DNA sequencing that runs on its C1TM Single-Cell Auto Prep System. This workflow streamlines targeted, whole exome and whole genome sequencing in heterogeneous cell populations and enables researchers to discover and screen somatic mutations, such as SNP, small indels, and translocations.

Study finds link between genes affected by testosterone and antibody responses to influenza vaccine

A new study has identified a link between certain genes affected by testosterone and antibody responses to an influenza vaccine. The findings, published in Proceedings of the National Academy of Sciences, suggest that testosterone levels may partially explain why men often have weaker responses to vaccines than women.

PAZ extracts may be useful option for improving plasma cholesterol profile

Health Enhancement Products, Inc., in conjunction with Wayne State University's Department of Nutrition and Food Science in the College of Liberal Arts and Sciences, announces the publication of a scientific article in the Journal of Nutrition & Metabolism, "ProAlgaZyme sub-fraction improves the lipoprotein profile of hypercholesterolemic hamsters, while inhibiting production of betaine, carnitine, and choline metabolites."

Manipulating epigenetic mechanism may promote cell death in pediatric brain cancer

Researchers at the Federal University of Rio Grande do Sul, the university hospital (Hospital de Cl-nicas de Porto Alegre, HCPA) and the Children's Cancer Institute (Instituto do C-ncer Infantil do Rio Grande do Sul, ICI-RS) in Porto Alegre, Brazil, have shown that manipulating an epigenetic mechanism, which regulates gene expression, may promote cell death and favor maturation towards less malignant-prone phenotypes in pediatric brain cancer cell lines.

MSCs isolated from MS patients have decreased suppressive function

Multiple sclerosis, an inflammatory autoimmune disease affecting more than one million people worldwide, is caused by an immune reaction to myelin proteins, the proteins that help form the myelin insulating substance around nerves. Demyelination and MS are a consequence of this immune reaction. Bone marrow mesenchymal stem cells have been considered as an important source for cell therapy for autoimmune diseases such as MS because of their immunosuppressive properties.

Arizona scientists investigate intriguing effects of spaceflight on microbial pathogens

At Arizona State University's Biodesign Institute, Cheryl Nickerson and her team have been investigating the intriguing effects of spaceflight on microbial pathogens.

Scientists establish a goal of creating vaccine gene chip to speed up vaccine testing

Testing the efficacy of vaccines in clinical trials takes years, even decades. Yet challenging infections like HIV, malaria and dengue are striking today. To speed up vaccine testing, scientists at the Emory Vaccine Center have established a goal of creating a "vaccine gene chip."

PAM50 FDA-cleared breast cancer test to be launched at ARUP Laboratories

The PAM50 breast cancer signature developed at the University of Utah and Huntsman Cancer Institute received FDA approval and will launch at ARUP Laboratories in Salt Lake City. The test utilizes gene expression data from 50 genes weighted together with clinical variables to generate a risk category and numerical score to assess a patient's risk of distant recurrence at ten years in postmenopausal women with node-negative (Stage I or II) or node-positive (Stage II), Hormone Receptor-Positive (HR+) breast cancer.

Study could lead towards a personalised medicine for chemoresistant lymphomata

To date, tests have only been carried out on cells, but a piece of research conducted by the Department of Genetics at the UPV/EHU's Faculty of Medicine in collaboration with MD Anderson and the CNIO is opening up the door for the treatment of lymphoma types that have a lower survival rate. The study of the molecular characteristics of the tumours would enable molecules that are altered in a specific way to be identified and turned into new therapeutic targets that would improve the prognosis of patients with chemoresistant lymphomata.

Eleven researchers receives 2014 DeLill Nasser Award for Professional Development in Genetics

The Genetics Society of America (GSA) is pleased to announce the selection of eleven early career researchers - five graduate students and six postdoctoral researchers - as recipients of a spring 2014 DeLill Nasser Award for Professional Development in Genetics.

Study shows effectiveness of PAM50-based Prosigna Breast Cancer Prognostic Gene Signature Assay

NanoString Technologies, Inc., a provider of life science tools for translational research and molecular diagnostic products, today announced new results from a combined analysis of the Austrian Breast & Colorectal Cancer Study Group 8 (ABCSG-8) and Trans-Arimidex, Tamoxifen, Alone or in Combination (TransATAC) studies. These results, which evaluated samples from 2,137 patients, suggest that the PAM50-based Prosignaz Breast Cancer Prognostic Gene Signature Assay may help identify women with late distant recurrence after five years of endocrine treatment.

Spaceflights cause cellular-level damage and may lead to long-term vision problems

Those who travel to space are rewarded with a beautiful sight - planet Earth. But the effects of space travel on the human sense of sight aren't so beautiful. More than 30 percent of astronauts who returned from two-week space shuttle missions and 60 percent who spent six months aboard the International Space Station were diagnosed with eye problems. Two recent investigations examined mechanisms that may explain eye changes in spaceflight, help find ways to minimize this health risk to astronauts and eventually prevent and treat eye diseases on Earth.

Lund University researcher explores why type 2 diabetes raises dementia risk later in life

It is well known that type 2 diabetes raises the risk of dementia. The reasons for this are less clear, but one explanation could be insulin resistance in the brain, according to Malin Wennstr-m, a researcher at Lund University's Molecular Memory Research Unit. She has received EUR 700,000 from the Swedish Research Council to investigate her theory.
