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.

Mice have different neural subsystem associated with instinctually important smells

A new study finds that mice have a distinct neural subsystem that links the nose to the brain and is associated with instinctually important smells such as those emitted by predators. That insight, published online this week in Proceedings of the National Academy of Sciences, prompts the question whether mice and other mammals have specially hardwired neural circuitry to trigger instinctive behavior in response to certain smells.

Human brown fat may actually be beige

Beige fat cells are more closely related to white than brown fat cells, say researchers who found that brown fat deposits in humans appear to be composed of beige cells.

Novel genomic sequencing method can help conduct in-depth analysis of single cells

Only by viewing a Georges Seurat painting at close range can you appreciate the hidden complexities of pointillism - small, distinct dots of color applied to form an image from a distance. Similarly, biologists and geneticists have long sought to analyze profiles of genes at the single cell level but technology limitations have only allowed a view from afar.

Protein associated with Huntington’s and other neurodegenerative diseases has several brain-specific forms

A protein essential for metabolism and recently associated with neurodegenerative diseases also occurs in several brain-specific forms. This discovery emerged in the course of a research project funded by the Austrian Science Fund FWF, the findings of which have now been published in the journal Human Molecular Genetics.

Researchers link specific gene mutations with four recognized subtypes of medulloblastoma

Researchers at Dana-Farber/Children's Hospital Cancer Center (DF/CHCC) and several collaborating institutions have linked mutations in specific genes to each of the four recognized subtypes of medulloblastoma, the most common malignant brain tumor of children. The discovery, reported July in the journal Nature, provides doctors with potential biomarkers for guiding and individualizing treatment and reveals prospective therapeutic opportunities for countering this devastating malignancy.

Natural compound can virtually eradicate HIV in infected culture cells

A new study by scientists on the Florida campus of The Scripps Research Institute shows, in cell culture, a natural compound can virtually eliminate human immunodeficiency virus (HIV) in infected cells. The compound defines a novel class of HIV anti-viral drugs endowed with the capacity to repress viral replication in acutely and chronically infected cells.

Researchers discover potential drug targets that might reduce ventilator-induced lung inflammation

When hospital patients need assistance breathing and are placed on a mechanical ventilator for days at a time, their lungs react to the pressure generated by the ventilator with an out-of-control immune response that can lead to excessive inflammation, new research suggests.

Premier research institutions, Biogen Idec partner to sequence genomes of patients with ALS

Biogen Idec today announced that it has entered into a research collaboration with premier academic and research institutions to sequence the genomes of up to 1,000 patients with amyotrophic lateral sclerosis (ALS) in an effort to gain a deeper understanding about the fundamental genetic causes of ALS.

Scientists discover new way to convert cord blood cells into iNC

For more than 20 years, doctors have been using cells from blood that remains in the placenta and umbilical cord after childbirth to treat a variety of illnesses, from cancer and immune disorders to blood and metabolic diseases.

New CD141hi DC subset plays a critical role in activating immune response against pathogens

Scientists at A*STAR's Singapore Immunology Network (SIgN), in collaboration with Newcastle University, UK, the Singapore Institute of Clinical Sciences and clinicians from multiple hospitals in Singapore, have identified a new subset of dendritic cells (DCs) in human peripheral tissue which have a critical role in activating our immune response against harmful pathogens.

Two cellular proteins team up to provide steady supply of RBCs

Two cellular proteins team up to provide a steady supply of red blood cells (RBCs), according to a study by Lizhao Wu, PhD, of the University of Medicine and Dentistry of New Jersey-New Jersey Medical School, and colleagues.

OncoMed commences dosing in OMP-54F28 Phase I clinical trial for advanced solid tumor cancers

OncoMed Pharmaceuticals, Inc., a clinical-stage company developing novel therapeutics that target cancer stem cells, or tumor-initiating cells, today announced that patient dosing has begun in a Phase I clinical trial of OMP-54F28 in patients with advanced solid tumor cancers.

BGI, BioMed Central launch GigaScience journal

BGI, the world's largest genome sequencing institute, and their publishing partner BioMed Central, a leader in scientific data sharing, announce the launch of a new journal, GigaScience, which publishes large-scale biological research in a unique format.

Genes responsible for immune function are almost different in middle age than in early adulthood

Important insights that explain why our ability to ward off infection declines with age are published in a new research report in the July 2012 issue of the Genetics Society of America's journal, GENETICS.

Oligodendroglia cells: An interview with Jeffrey Rothstein

There are three principle cells in the brain: neurons and two types of glial cells. One type is called an astrocyte. These were well known to inactivate neurotransmitters like glutamate, and provide metabolic support to neurons.

Research into “insulating” brain cells could help to cure neurodegenerative diseases such as ALS

Johns Hopkins researchers say they have discovered that the central nervous system's oligodendroglia cells, long believed to simply insulate nerves as they "fire" signals, are unexpectedly also vital to the survival of neurons. Damage to these insulators appears to contribute to brain injury in neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease for the Yankee baseball great who died from the disease.

Genetic test helps avoid needless thyroid surgery

US researchers report that a gene-based test may help to identify patients who have cytologically indeterminate thyroid nodules that are benign.

Disabling Nf1 gene makes stem cells from the third ventricle proliferate rapidly

Scientists showed in mice that disabling a gene linked to a common pediatric tumor disorder, neurofibromatosis type 1 (NF1), made stem cells from one part of the brain proliferate rapidly. But the same genetic deficit had no effect on stem cells from another brain region.

MammaPrint more cost-effective and clinically-useful test than Oncotype DX

New research from University of the Sciences' Mayes College of Healthcare Business and Policy suggests that MammaPrint - a gene expression profiling (GEP) test used to identify whether women with early-stage breast cancer would benefit from chemotherapy - is the more cost-effective and clinically-useful test than the most frequently used GEP in practice in the United States today.
