Researchers visualize vasculature within native liver cyst walls of human ADPKD patients

As part of an effort to develop effective medical therapies that block the progression of liver cyst growth in patients with Autosomal Dominant Polycystic Kidney Disease (ADPKD), researchers at the University of Colorado Anschutz Medical Center have found that the liver cyst walls develop and maintain a vasculature as they grow out from the body of the liver and that factors released by epithelial cells that line the liver cyst wall lumen can drive the proliferation and development of vascular endothelial cells.

Phenotype microarrays compare growth characteristics of pathogenic and non-pathogenic E. coli

Dr Karin Heurlier and colleagues at the Universities of Nottingham and Birmingham in conjunction with Biolog Inc of California USA, used powerful high throughput analytical tools (phenotype microarrays) that enabled them to compare about 2000 growth characteristics of several pathogenic (disease-causing) E. coli with a non-pathogenic laboratory E. coli strain.

New risk index for COPD developed to estimate the risk of death

Researchers from the Centre for Research in Environmental Epidemiology (CREAL) and the Municipal Institute of Medical Research (IMIM-Hospital del Mar), in collaboration with the Hospital Clínic of Barcelona, have participated in an international consortium that has developed a new risk index for COPD patients. With this index, doctors can assess disease severity more objectively and estimate the risk of death.

Predictors of disease behavior change in patients with Crohn's disease

Using the Vienna classification system, it has been shown in clinic-based cohorts that there can be a significant change in disease behavior over time, whereas disease location remains relatively stable. Clinical and environmental factors as well as medical therapy might be relevant in predicting disease behavior change in patients with CD.

Discovery of mechanism that protects somatic cells against the behaviour of germ cells

An IRB Barcelona research team discovers the mechanism that favors the correct separation of germ cells -- future ovules and sperm -- from the rest of the cells during embryonic development

Discovery of novel tumor suppressor

La Jolla Institute for Allergy & Immunology researchers studying an enzyme believed to play a role in allergy onset, instead have discovered its previously unknown role as a tumor suppressor that may be important in myeloproliferative diseases and some types of lymphoma and leukemia. Myeloproliferative diseases are a group of disorders characterized by an overproduction of blood cells by the bone marrow and include chronic myeloid leukemia. Lymphoma and leukemia are cancers of the blood.

Miglustat shows promise for cystic fibrosis

Miglustat is a drug currently under phase 2 clinical trials on patients suffering from cystic fibrosis (1). Its potential for treating the disease was discovered in 2006 thanks to the work of Frédéric Becq's team at the Institute of Cell Physiology and Biology (CNRS/Université de Poitiers), funded by the associations Vaincre la Mucoviscidose, MucoVie66, La Pierre Le Bigaut and ABCF2.

A new take on growth factor signaling in tamoxifen resistance

Differences in growth factor (GF) signaling may cause the poor prognosis in some breast cancer cases. A new study, published in the open access journal BMC Medical Genomics, suggests that some estrogen receptor-positive breast cancers respond poorly to tamoxifen because of increased GF signaling.

Don't stress when the going gets tough - you'll go gray!

A study by Japanese researchers has revealed that a certain kind of stress damages the hair - they say "genotoxic stress" damages DNA by depleting the melanocyte stem cells (MSCs) within hair follicles that are responsible for making the pigment-producing cells.

HER2/neu protein predicts development of invasive breast cancer in women with ductal carcinoma in situ

Women with ductal carcinoma in situ (DCIS) who exhibit an overexpression of the protein HER2/neu have a six-fold increase in risk of invasive breast cancer, according to a new study from the University of Pennsylvania School of Medicine.

Tuberculosis can evade immune response

Current research suggests that Mycobacterium tuberculosis can evade the immune response. The related report by Rahman et al, "Compartmentalization of immune responses in human tuberculosis: few CD8+ effector T cells but elevated levels of FoxP3+ regulatory T cells in the granulomatous lesions," appears in the June 2009 issue of The American Journal of Pathology.
