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.

Genetic screening identifies genes driving resistance with guide RNA library

Researchers have developed a method to create a comprehensive library of mutations across all genes in the mouse genome. This library can be used to examine the role of every gene in different cell types.

Finding suggests new route for packaging RNA molecules of interest into nanovesicles

The role of microRNAs is fundamental for the correct moment-to-moment adjustment in the expression of target genes. "Before this study, we already knew that these small molecules could be packaged into small vesicles and exported to the extracellular space, to be later captured by other cells and in this way play an important role in intercellular communication," explains CNIC researcher Carolina Villarroya, the first author on the study.

Study supports mounting evidence that inflammation may be the cause of chronic rhinosinusitis

Saint Louis University researchers have analyzed the microbiomes of people with chronic rhinosinusitis and healthy volunteers and found evidence that some chronic sinus issues may be the result of inflammation triggered by an immune response to otherwise harmless microorganisms in the sinus membranes.

Research findings point to possible new strategy for treating ALS

Amyotrophic lateral sclerosis, better known as Lou Gehrig's disease, is a devastating illness that gradually robs sufferers of muscle strength and eventually causes a lethal, full-body paralysis. The only drug available to treat the disease extends life spans by a meager three months on average.

WSU researchers discover how Nipah virus employs burglary-ring-like teamwork to infiltrate human cell

A team of scientists from Washington State University has discovered how one of the planet's most deadly known viruses employs burglary-ring-like teamwork to infiltrate the human cell.

Researchers construct "golden trap" capable of capturing molecules

The method's high sensitivity lies in the customized environment for the substance of interest. Dresden's Adrian Keller and his colleagues have constructed a type of "golden trap" capable of capturing the molecules and thereby enabling their detection.

Gilead Sciences gets FDA approval for once-daily single tablet HIV-1 regimen Complera

Gilead Sciences, Inc. today announced that the U.S. Food and Drug Administration has approved the single tablet HIV-1 regimen Complera (emtricitabine/rilpivirine/tenofovir disoproxil fumarate) for use in certain virologically-suppressed (HIV RNA <50 copies/mL) adult patients on a stable antiretroviral regimen in order to replace their current antiretroviral treatment regimen. Complera was first approved in 2011 for patients new to therapy and is now one of the most widely-prescribed HIV regimens in the United States.

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.

New mutations in the estrogen receptor drive strong drug resistance exhibited by human breast tumors

Human breast tumors transplanted into mice are excellent models of metastatic cancer and are providing insights into how to attack breast cancers that no longer respond to the drugs used to treat them, according to research from Washington University School of Medicine in St. Louis.

Study: Antisense drugs show activity in wide range of tissues and organs

Antisense therapeutics, a class of drugs comprised of short nucleic acid sequences, can target a dysfunctional gene and silence its activity. A new study has shown that antisense drugs delivered systemically show activity in a wide range of tissues and organs, supporting their broad therapeutic potential in many disease indications, as described in an article in Nucleic Acid Therapeutics, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.

Ribosomal proteins RPL5, RPL11 play essential role in normal cell proliferation

Researchers from the Laboratory of Cancer Metabolism (LCM) led by George Thomas at the Bellvitge Biomedical Research Institute (IDIBELL), the Catalan Institute of Oncology (ICO) and the Division of Hematology/ Oncology, University of Cincinnati, have shown that loss of either one of two tumor suppressors, ribosomal proteins RPL5 or RPL11, fail to induce cell-cycle arrest, but prevent the proliferation of cells as they have a reduced capacity to synthesize proteins.
