Cereblon protein now holds hope in fight against multiple myeloma

Research on the same protein that was a primary mediator of the birth defects caused by thalidomide now holds hope in the battle against multiple myeloma, say Mayo Clinic researchers who presented results of several clinical trials at the 53nd annual meeting of the American Society of Hematology Dec. 10-13 in San Diego.

MPC project to study how plant genes contribute to producing medicinal compounds

Scientists are about to make publicly available all the data they have so far on the genetic blueprint of medicinal plants and what beneficial properties are encoded by the genes identified.

Researchers identify genetic factors responsible for neurons in the thalamus

The thalamus is the central translator in the brain: Specialized nerve cells (neurons) receive information from the sensory organs, process it, and transmit it deep into the brain. Researchers from the Institute of Toxicology and Genetics (ITG) of KIT have now identified the genetic factors Lhx2 and Lhx9 responsible for the development of these neurons.

First mobile safety lab for South African patients with AIDS and TB

The first mobile safety laboratory to operate under Biosafety Level 3 has been in use in South Africa since May 2011. As development of the Fraunhofer Institute for Biomedical Engineering in St. Ingbert, this special truck is used for testing and advising patients with AIDS and tuberculosis. The mobile laboratory can save patients' lives in remote areas because it cuts the waiting time between diagnosis and the start of treatment to just one day.

M. pneumoniae CARDS toxin plays a critical role in asthma

Five years ago, microbiologists at The University of Texas Health Science Center San Antonio discovered the toxin produced by a common respiratory bacterial pathogen, Mycoplasma pneumoniae. Joel Baseman, Ph.D., who led the discovery, said at the time that the toxin's presence in humans could be causing as many as 40 percent of all asthma cases.

Multiple CT scans can increase risk of cancer

From the doctor's office to the airport, Americans have more opportunity for radiation exposure than ever before. While low levels of radiation are used in medical imaging and airport body scanners, there is much debate about exposure levels and potential cancer risks. New research from Wake Forest Baptist Medical Center has found that there could be an increased risk of cancer for certain individuals who are exposed to multiple CT scans.

Small genetic changes may increase risk of schizophrenia

Carrying single DNA letter changes from two different genes together may increase the risk of developing schizophrenia, Johns Hopkins researchers reported in the November 16 issue of Neuron.

MDC professor to receive Gottfried Wilhelm Leibniz Prize

Professor Nikolaus Rajewsky of the Max Delbr-ck Center for Molecular Medicine (MDC) Berlin is to receive Germany's most prestigious research award, the Gottfried Wilhelm Leibniz Prize.

Nitroglycerin can boost body's natural immune response to cancer

Researchers at Queen's University have identified a new mechanism that could potentially explain why the body's immune system sometimes fails to eliminate cancer. The new findings shed light on the possible cause of immune resistance in cancer cells, and indicate that nitroglycerin, a relatively safe and low-cost drug used for more than a century to treat angina, may be effective for managing certain cancers.

Modern humans have a better sense of smell than Neanderthals

Compared to Neanderthals, modern humans have a better sense of smell. Differences in the temporal lobes and olfactory bulbs also suggest a combined use of brain functions related to cognition and olfaction. The increase of brain size is intimately linked to the evolution of humanity. Two different human species, Neanderthals and modern humans, have independently evolved brains of roughly the same size but with differing shapes. This could indicate a difference in the underlying brain organization.

Isis announces addition of three new drug development candidates

Isis Pharmaceuticals, Inc. announced today that it has added three new drugs to its development pipeline, ISIS-APOARx, ISIS-DGAT2Rx and ISIS-FVIIRx.

Researchers discover novel viral oncogenesis mechanism

Human tumor viruses contribute to 15-20% of human cancers worldwide. Kaposi's sarcoma herpesvirus (KSHV) is an etiological agent for Kaposi's sarcoma (KS) and two other rare lymphoproliferative malignancies. KS is the most common cancer in HIV-infected untreated individuals and remains a primary cause of cancer deaths in many subequatorial African countries as a result of the AIDS pandemic.

Fast Forward, Lineagen to fund clinical development and validation of blood-based assay for MS

Lineagen, Inc., an innovative molecular diagnostics company focused on complex, genetically linked disorders, and Fast Forward, LLC, a nonprofit subsidiary of the National Multiple Sclerosis Society, today announced an alliance to fund the clinical development and validation of a blood-based assay for multiple sclerosis.

Liver transplantations for NASH-Cirrhosis increase dramatically

Nonalcoholic steatohepatitis (NASH) occurs when fat builds up in the liver. This accumulation of fat damages the liver and leads to cirrhosis. NASH is rapidly increasing in the U.S. mainly related to the epidemics of obesity and diabetes.

DCC gene protects mice from onset of colon cancer

The research team at Lyon has developed an animal model carrying a mutation of the DCC gene. Mice carrying the mutation develop tumours, because this gene can no longer induce the death of the cancer cells. This discovery could lead to the development of a new targeted cancer treatment that aims to reactivate the dying of cancer cells.

Researchers develop mouse model to investigate fenugreek allergy

A mouse model to investigate allergy to fenugreek has been developed by Norwegian researchers. The model can also be used to study cross-reactivity to peanut, soy and lupin, major food allergens with public health relevance.

Antioxidant can delay onset of all indicators of Alzheimer's

When you cut an apple and leave it out, it turns brown. Squeeze the apple with lemon juice, an antioxidant, and the process slows down. Simply put, that same "browning" process-known as oxidative stress-happens in the brain as Alzheimer's disease sets in. The underlying cause is believed to be improper processing of a protein associated with the creation of free radicals that cause oxidative stress.

Novel prognostic model for patients with treatment-related MDS

A large-scale analysis of patients whose myelodysplastic syndrome is related to earlier cancer treatment overturns the notion that all of them have a poor prognosis, researchers from The University of Texas MD Anderson Cancer Center report at the 53rd Annual Meeting of the American Society of Hematology.

Molecular signature indicative of hypoxia predicts progression to AD

A study led by Research Professor Matej Ore-ič from VTT Technical Research Centre of Finland suggests that Alzheimer's disease is preceded by a molecular signature indicative of hypoxia and up-regulated pentose phosphate pathway.

Dendrimers offers a new way to treat age-related macular degeneration, retinitis pigmentosa

Hitching a ride into the retina on nanoparticles called dendrimers offers a new way to treat age-related macular degeneration and retinitis pigmentosa. A study by investigators at Mayo Clinic, Wayne State University and Johns Hopkins Medicine shows that steroids attached to the dendrimers target the damage-causing cells associated with neuroinflammation, leaving the rest of the eye unaffected and preserving vision.
