Genomic discovery: Protecting kidney function during heart failure

Mayo Clinic cardiology researchers have found a peptide that helps preserve and improve kidney function during heart failure, without affecting blood pressure. Earlier variations of this peptide caused blood pressure to drop limiting the potential benefits to the kidneys. The findings appear in the current Proceedings of the National Academy of Sciences.

A novel and universal method for microRNA data analysis

Our understanding of the importance of microRNAs in regulating gene expression is expanding, and with it our requirement for robust methods to measure their expression levels. Now a new method published in BioMed Central's open access journal Genome Biology helps researchers to better understand the delicate interplay between differences in microRNA expression levels and their target genes.

Oxidative stress strongly evident in the in-utero environment of the fetus with Down syndrome

A paper published in the Proceedings of the National Academy of Sciences by Tufts Medical Center and Tufts University researchers reports that amniotic fluid surrounding Down syndrome fetuses shows oxidative stress, a condition that could harm fetal cells and play a role in affected individuals. The results demonstrate secondary adverse consequences of Down syndrome and suggest potential prenatal therapies.

Discovery of genetic link between periodontitis and heart attack

The relationship between the dental disease periodontitis and coronary heart disease (CHD) has been known for several years. Although a genetic link seemed likely, until now its existence was uncertain. Now, for the first time, scientists have discovered a genetic relationship between the two conditions, a researcher told the annual conference of the European Society of Human Genetics today (Monday 25 May).

Getting more from whole-transcript microarrays

The widely-used Affymetrix Whole-Transcript Gene 1.0 ST (sense target) microarray platform, normally used to assay gene expression, can also be utilized to interrogate exon-specific splicing. Research published today in the open access journal BMC Bioinformatics shows scientists how to monitor alternative splicing activity on a genome-wide scale, without investing in new exon microarray technologies.

Research brings quick, precise view of cell development and gene expression

A team of University of Oregon biologists, using fruit flies, has created a way to isolate RNA from specific cells, opening a new window on how gene expression drives normal development and disease-causing breakdowns.

Amino acid glutamine show promise in treating stomach ulcers

Nearly 20 years ago, it was discovered that bacteria known as Helicobacter pylori were responsible for stomach ulcers. Since then, antibiotics have become the primary therapy used to combat the H. pylori infection, which affects approximately six percent of the world population and is also a primary cause of stomach cancer. But today the bacteria is growing increasingly resistant to antibiotics.

The effect of tea polyphenols on paracetamol-induced hepatotoxicity

Paracetamol is one of the most widely used, studied, and arguably the most notorious hepatotoxic drugs, which is safe at therapeutic doses but causes liver failure when overdosed.

New insights into transcription factors in human cells

Bioinformatics researchers from UC San Diego just moved closer to unlocking the mystery of how human cells switch from "proliferation mode" to "specialization mode."

Study looks at shikonin for human gastric adenocarcinoma

Previous studies on shikonin, a chemical derived from the Chinese medicinal herb had anti-tumor effects although it was found to be toxic.

Key genetic mechanism a potential key to new class of antibiotics

Researchers have determined the structure of a key genetic mechanism at work in bacteria, including some that are deadly to humans, in an important step toward the design of a new class of antibiotics, according to an accelerated publication that appeared online today as a "paper of the week" in the Journal of Biological Chemistry.

Mammalian alpha-fetoprotein affects the development of rat colons

Mammalian alpha-fetoprotein (AFP) is a single-chain glycoprotein and altered serum AFP levels have been observed concurrent with aberrant growth manifestations in some congenital defects and cancer.

Scientists use RNA to reprogram 1 cell type into another

For the past decade, researchers have tried to tweak cells at the gene and nucleus level to reprogram their identity.

Researchers study signaling networks that set up genetic code

In a new study, researchers at the University of Illinois have identified and visualized the signaling pathways in protein-RNA complexes that help set the genetic code in all organisms.

microRNAs manipulate cells to one day create safe embryonic-like stem cells

A team of UCSF researchers has for the first time used tiny molecules called microRNAs to help turn adult mouse cells back to their embryonic state.

Synthetic green-glowing genes show how 'silent' mutations influence protein production

Biologists at the University of Pennsylvania have revealed a hidden code that determines the expression level of a gene, providing a way to distinguish efficient genes from inefficient ones.

RNA interference can be used to silence genes selectively - potential for Huntington's disease therapy

Howard Hughes Medical Institute researchers have designed tiny RNA molecules that shut off the gene that causes Huntington's disease without damaging that gene's healthy counterpart, which maintains the health and vitality of neurons.
