A new mouse model for the study of neurofibromatosis
2015-04-16
(Press-News.org) The research group of the neurofibromatosis of the Catalan Institute of Oncology (ICO), the Institute of Biomedical Research of Bellvitge (IDIBELL) and the Institute of Medicicina Predictive and Personalized Cancer (IMPPC) has developed new mouse models for the study of principal malignant tumor associated with neurofibromatosis type 1.
Details of the development and characterization of new animal models have been published in EMBO Molecular Medicine.
Neurofibromatosis, a rare and minority
The neurofibromatosis are disorders of the nervous system that primarily affect the development and growth of neural tissue cells.
Neurofibromatosis type 1 is the most common form, affecting one in 3,500 people, approximately. It is caused by mutations in the NF1 gene, located on chromosome 17. The involvement of this gene can cause a diverse range of health problems, such as tumors on the skin and nervous system.
In this sense, the primary malignant tumor associated with neurofibromatosis type 1 is called malignant tumor of the peripheral nerve sheath. It belongs to the group of soft tissue sarcomas, there is no effective treatment and is associated with poor survival.
New animal models
ICO-IDIBELL-IMPPC team has created what is called orthotopic tumor models, ie have successfully implanted human tumor mouse relevant body and develop as you would in person.
The EMBO Molecular Medicine study shows how the animal model reproduces histological, genetic and epigenetic human tumor characteristics and patterns of spread, which is not achieved with other methods of implementation.
Until now there were no animal models based on direct transplantation of primary tumors originating in these patients. This group has generated five different models using immunosuppressed mice implanted with malignant tumors of peripheral nerve sheath in the same tissue where the tumors originate in humans.
These animal models allow a better study of tumor and promote personalized medicine. If required, you might have a mouse with tumor of each patient so that you can predict how it will develop and decide in each case what the most appropriate treatment for each patient will be.

A new study is a rare look into the delicate dynamics of social movement, and shows how people avoid bumping into each other while doing complementary, coordinated tasks such as dancing. The research reveals that people fall into a specific pattern to avoid a collision. The study led by Michael J. Richardson, a University of Cincinnati associate professor of psychology, is published in the highly ranked Journal of Experimental Psychology: Human Perception and Performance, a journal of the American Psychological Association.
The study involved 12 pairs of two participants ...

The exchange of words, speaking and listening in conversation, may seem unremarkable for most people, but communicating with others is a challenge for people who have aphasia, an impairment of language that often happens after stroke or other brain injury. Aphasia affects about 1 in 250 people, making it more common than Parkinson's Disease or cerebral palsy, and can make it difficult to return to work and to maintain social relationships. A new study published in the journal Nature Communications provides a detailed brain map of language impairments in aphasia following ...

Three or more hours of walking per week can boost the vitality and health of prostate cancer survivors. Men and women who have survived colorectal cancer and are regular walkers as well report lower sensations of burning, numbness, tingling or loss of reflexes that many often experience post-treatment. These are among the findings of two studies published in Springer's Journal of Cancer Survivorship that highlight the benefits of exercise for cancer survivors.
In the first, a group of American researchers led by Siobhan Phillips of Northwestern University weighed up the ...

One of the immune system's most critical challenges is to differentiate between itself and foreign invaders -- and the number of recognized autoimmune diseases, in which the body attacks itself, is on the rise. But humans are not the only organisms contending with "friendly fire."
Even single-celled bacteria attack their own DNA. What protects these bacteria, permitting them to survive the attacks?
A new study published in Nature by a team of researchers at Tel Aviv University and the Weizmann Institute of Science now reveals the precise mechanism that bacteria's defense ...

(PHILADELPHIA) - As cesarean section rates continue to climb in the United States, researchers are looking to understand the factors that might contribute. There has been debate in the field about whether non-medically required induction of labor leads to a greater likelihood of C-section, with some studies showing an association and others demonstrating that inductions at full term can actually protect both the mothers and babies. In order to tease apart the evidence, a new analysis pooled the results from five randomized controlled trials including 844 women, and found ...

Berkeley - A new study quantifying the amount of carbon stored and released through California forests and wildlands finds that wildfires and deforestation are contributing more than expected to the state's greenhouse gas emissions.
The findings, published online today (Wednesday, April 15), in the journal Forest Ecology and Management, came from a collaborative project led by the National Park Service and the University of California, Berkeley. The results could have implications for California's efforts to meet goals mandated by the state Global Warming Solutions Act, ...

Researchers at the Angiocardioneurology Department of the Neuromed Scientific Institute for Research, Hospitalisation and Health Care of Pozzilli (Italy), have found, in animal models, that the absence of a certain enzyme causes a syndrome resembling the Attention Deficit Hyperactivity Disorder (ADHD). The study, published in the international journal EMBO Molecular Medicine, paves the way for a greater understanding of this childhood and adolescent disease, aiming at innovative therapeutic approaches.
Described for the first time in 1845, but came to the fore only in ...

HEIDELBERG, 15 April 2015 - A genetic investigation of individuals in the Framingham Heart Study may prove useful to identify novel targets for the prevention or treatment of high blood pressure. The study, which takes a close look at networks of blood pressure-related genes, is published in the journal Molecular Systems Biology.
More than one billion people worldwide suffer from high blood pressure and this contributes significantly to deaths from cardiovascular disease. It is hoped that advances in understanding the genetic basis of how blood pressure is regulated ...

Philadelphia, PA, April 16, 2015 - About 15% of patients with Lyme disease develop peripheral and central nervous system involvement, often accompanied by debilitating and painful symptoms. New research indicates that inflammation plays a causal role in the array of neurologic changes associated with Lyme disease, according to a study published in The American Journal of Pathology. The investigators at the Tulane National Primate Research Center and Louisiana State University Health Sciences Center also showed that the anti-inflammatory drug dexamethasone prevents many ...

New York, NY--While a large number of women quit or reduce smoking upon pregnancy recognition, many resume smoking postpartum. Previous research has estimated that approximately 70% of women who quit smoking during pregnancy relapse within the first year after childbirth, and of those who relapse, 67% resume smoking by three months, and up to 90% by six months.
A new study out in the Nicotine & Tobacco Research indicates the only significant predictor in change in smoking behaviors for women who smoked during pregnancy was in those who breastfed their infant, finding ...
