Cell signaling is vital for cells to communicate and coordinate their activities, not just in the human body, but in all organisms. There are thousands of signaling pathways, ranging from protein homeostasis to carcinogenesis and biofilm formation.

Cell-to-cell signaling pathway that designates future location of ear's sensory organs tracked

Researchers have tracked a cell-to-cell signaling pathway that designates the future location of the ear's sensory organs in embryonic mice. The scientists succeeded in activating this signal more widely across the embryonic tissue that becomes the inner ear. Patches of sensory structures began growing in spots where they don't normally appear.

Study identifies four genetic variants associated with ESRD disease in Chinese diabetic patients

Examination of a gene involved in cell signaling finds that four common variants of this gene are associated with the development of end-stage renal disease in Chinese patients with type 2 diabetes, according to a study in the August 25 issue of JAMA.

Wellcome Trust supports research on role of 'rotten eggs' as an anti-inflammatory agent

A research project at the Peninsula Medical School in Exeter, which will study the effect of hydrogen sulfide (H2S - the 'rotten eggs' gas) as an effective anti-inflammatory agent, has won a research grant of -140,000 over three years from the Wellcome Trust.

Research on ocean-dwelling bacterium unveils food poisoning mechanism in human

Researchers at UT Southwestern Medical Center have uncovered a key weapon in the molecular arsenal the infectious bacterium Vibrio parahaemolyticus (V. para) uses to kill cells and cause food poisoning in its human host.

Researchers find link between chronic inflammation and cancer

Virginia Commonwealth University Massey Cancer Center researchers have uncovered a new link between chronic inflammation and cancer. Although cancers do not always cause inflammation, chronic inflammation is known to help tumor cells grow.

New MIC platform measures cell-signaling pathways in brain tumor samples at single-cell level

New technologies for the diagnosis of cancer are rapidly changing the clinical practice of oncology. As scientists learn more about the molecular basis of cancer, the development of new tools capable of multiple, inexpensive biomarker measurements on small samples of clinical tissue will become essential to the success of genetically informed and personalized cancer therapies.

Scientists discover technique for more controlled lab experiments on cellular mechanobiology

Bioengineers at the University of Pennsylvania have created a system to control the flexibility of the substrate surfaces on which cells are grown without changing the surface properties, providing a technique for more controlled lab experiments on cellular mechanobiology, an important step in the scientific effort to understand how cells sense and respond to mechanical forces in their environment.

Cetuximab recommended for colorectal cancer tumors without mutation in KRAS gene

In a report published in the July 2010 issue of the American Society for Clinical Oncology Post, new recommendations on the use of the drug cetuximab have been issued after officials halted enrollment in a phase III clinical trial in patients with spread of colon cancer into regional lymph nodes whose tumors had been surgically removed.

Penn researchers reverse cognitive decline in fruit flies with Alzheimer's gene mutation

Investigators have found that fruit fly (Drosophila melanogaster) males -- in which the activity of an Alzheimer's disease protein is reduced by 50 percent -- show impairments in learning and memory as they age. What's more, the researchers were able to prevent the age-related deficits by treating the flies with drugs such as lithium, or by genetic manipulations that reduced nerve-cell signaling.

Cigarette smoking affects entire networks of gene interaction: Research

The effects of smoking cigarettes on gene activity have been investigated in the largest study of its kind. Researchers writing in the open access journal BMC Medical Genomics studied white blood cells taken from 1,240 people to identify 323 unique genes whose expression levels were significantly correlated with smoking behavior.

Fluidigm's IFC platform products help perform digital-PCR measurements on single gene

Utilizing Fluidigm Corporation's Dynamic Array™ and Digital Array™ integrated fluidic circuits (IFCs), Stanford University researchers to have discovered a much larger spectrum of differences between individual cells than has previously been demonstrated. Among these differences are the communication capabilities that emerge from the interactions of genetic circuitry that mediates cell-to-cell communication.

PIKAMAB secures exclusive rights to issued U.S. patent from UABRF

PIKAMAB, a biopharmaceutical company specializing in stratified medicine, announced today that it has secured exclusive rights to an issued U.S. patent (US 6,986,987) from the UAB Research Foundation. This patent pertains to the discovery that the functional polymorphism (Ser/Gly248) in the cytoplasmic domain of Fc alpha receptor determines the proinflammatory potential of serum IgA autoantibodies through cell signaling and production of cytokines such as TNF-alpha, IL-6, and IL-1β in an allele-dependent manner.

Engineered allosteric regulation provides precise control of kinase activity in living cells

Cancer occurs when human cells move and multiply inappropriately. Within cells, a process called phosphorylation serves as an on/off switch for a number of cellular processes that can be involved in cancer, including metabolism, transcription, configuration, movement, cell death and differentiation. This process is controlled by a group of enzymes called protein kinases that - working together and separately - modify the structure of proteins, changing them and allowing them to control cellular processes.

UH researchers analyze 'wireless connections' in brain to prevent neurological diseases

Many diseases of brain function, such as epilepsy and schizophrenia, are caused by problems in how neurons communicate with each other. A University of Houston researcher and his team are analyzing these commands and connections in an attempt to prevent those diseases.
