Proteomics News and Research

RSS

The term 'proteome' was first coined in 1994, and refers to all the proteins in a cell, tissue, or organism. Proteomics refers to the study of the proteome. Because proteins are involved in almost all biological activities, the proteome is a rich source of biological information.

Expression of tyrosine kinases may limit effectiveness of agents against sarcomas

To better understand the signaling pathways active in sarcomas, researchers at Moffitt Cancer Center used state-of-the-art mass spectrometry-based proteomics to characterize a family of protein enzymes that act as "on" or "off" switches important in the biology of cancer. The tyrosine kinases they identified, the researchers said, could act as "drivers" for the growth and survival of sarcomas.

Breast-fed babies may have healthy gut microbial population

Early colonization of the gut by microbes in infants is critical for development of their intestinal tract and in immune development. A new study, published in BioMed Central's open access journal Genome Biology, shows that differences in bacterial colonization of formula-fed and breast-fed babies leads to changes in the infant's expression of genes involved in the immune system, and in defense against pathogens.

New studies on personalized lung cancer treatment presented at 3rd ELCC

Several new studies that may help doctors tailor lung cancer treatment to the characteristics of individual patients and of their tumors are being presented at the 3rd European Lung Cancer Conference in Geneva.

More insight into tangled proteins in Alzheimer's disease

In Alzheimer's disease, brain neurons become clogged with tangled proteins. Scientists suspect these tangles arise partly due to malfunctions in a little-known regulatory system within cells. Now, researchers have dramatically increased what they know about this particular regulatory system in mice. Such information will help scientists better understand Alzheimer's and other diseases in humans and could eventually provide new targets for therapies.

T-FET biosensor can detect biomolecules at ultra-low concentrations

A new quantum mechanical-based biosensor designed by a team at University of California, Santa Barbara offers tremendous potential for detecting biomolecules at ultra-low concentrations, from instant point-of-care disease diagnostics, to detection of trace substances for forensics and security.

KineMed receives NIH RAID grant to advance FX-5A for heart disease

KineMed Inc. today announced its successful award of a Rapid Access to Intervention Development (RAID) peer-reviewed grant by the National Institute of Health to advance an HDL mimetic, designated FX-5A, designed to reverse atherosclerosis and heart disease.

New microfluidics-based microarray can accurately detect breast cancer

One in eight women will be diagnosed with breast cancer during her lifetime. The earlier cancer is detected, the better the chance of successful treatment and long-term survival. However, early cancer diagnosis is still challenging as testing by mammography remains cumbersome, costly, and in many cases, cancer can only be detected at an advanced stage.

Simple genetic test could help predict aggressiveness of rhabdomyosarcoma tumours

A study led by Dr Janet Shipley from The Institute of Cancer Research (ICR) in London in collaboration with Dr Mauro Delorenzi from the SIB Swiss Institute of Bioinformatics in Lausanne has shown that a simple genetic test could help predict the aggressiveness of rhabdomyosarcoma tumours in children

Novel sensor selectively screens single molecules passing through nanopores

A novel type of sensor, based on nanometer-scale pores in a semiconductor membrane, is a step closer to practical use in applications such as analyzing the protein contents of a single cell. Researchers pioneering single-molecule nanopore sensor technology at the Technische Universit-t M-nchen (TUM) have shown its potential through a succession of experiments over the past few years.

Study reveals how mutation shuts down DJ-1 protein's neuroprotective abilities

Purdue University researchers revealed how a mutation in a protein shuts down a protective function needed to prevent the death of neurons in Parkinson's disease, possibly opening the door to new drug strategies to treat the disorder.

Scientists discover the off signal for inflammation

Proteins, the building block for all living organisms, are the ultimate transformers - able to splice and switch roles and functions within the human body. But when these changes go wrong, diseases such as cancers and arthritis may result, says University of British Columbia researcher Chris Overall.
