Eye transformer impacts JAK/STAT-signaling pathway response with microbial challenge

Scientists are keeping their eye on a new discovery published in the November 2011 print issue of the FASEB Journal (http://www.fasebj.org) that explains what causes some genes to go out of control. Scientists have identified a "cellular switch," called eye transformer, that controls the flow of information from chemical signals outside of the cell to genes in the cell nucleus.

Study reveals two enzymes help immune cells deploy pathogen-killing traps

A new study reveals that two enzymes help immune cells deploy pathogen-killing traps by unraveling and using the chromatin (DNA and its associated proteins) contained in the cells' nuclei to form defensive webs. The study appears online on October 25 in The Journal of Cell Biology.

Researchers suggest gene therapy may treat patients with major depression

In a report published in the Oct. 20 issue of Science Translational Medicine, researchers at NewYork-Presbyterian Hospital/Weill Cornell Medical Center say animal and human data suggest gene therapy to the brain may be able to treat patients with major depression who do not respond to traditional drug treatment.

New mechanism controlling transmission of abnormal signal at origin of several cancers identified

Researchers at the Institute for Research in Immunology and Cancer (IRIC) of the Universit- de Montr-al have identified a new mechanism controlling the transmission of an abnormal signal at the origin of several cancers. In an article published in the journal Cell, Marc Therrien's team explains the recent discovery of a protein complex that controls the RAS/MAPK signalling pathway, responsible for some of the deadliest cancers, including pancreatic, colon and lung cancers, and melanomas.

Researchers discover how cocaine corrupts brains' reward center

Mount Sinai researchers have discovered how cocaine corrupts the brain and becomes addictive. These findings-the first to connect activation of specific neurons to alterations in cocaine reward-were published in Science on October 15. The results may help researchers in developing new ways of treating those addicted to the drug.

Fluctuations in internal body temperature regulate body's circadian rhythm: Research

Researchers at UT Southwestern Medical Center have found that fluctuations in internal body temperature regulate the body's circadian rhythm, the 24-hour cycle that controls metabolism, sleep and other bodily functions.

Scientists identify mechanism that regulate nuclear size

Size matters when it comes to the nucleus of a cell, and now scientists have discovered the signals that control how big the nucleus gets. Nuclear size varies not only among different species, but also in different types of cells in the same species and at different times during development. In addition, cancer cells are known to develop larger nuclei as they become more malignant. Screening for cervical cancer, for example, involves looking for grossly distorted nuclei in cervical cells collected during a Pap smear.

Scientists identify root cause of chromosomal errors and gene diversity

A team led by a scientist at the University of Pittsburgh School of Medicine has discovered a regulatory protein that influences where genetic material gets swapped between maternal and paternal chromosomes during the process of creating eggs and sperm. The findings, which shed light on the roots of chromosomal errors and gene diversity, appear in tomorrow's issue of Nature.

Researchers develop new method to identify chemical histone modifications

Test system on Drosophila should provide the key to histone function. The genetic inherited material DNA was long viewed as the sole bearer of hereditary information. The function of its packaging proteins, the histones, was believed to be exclusively structural. Additional genetic information can be stored, however, and passed on to subsequent generations through chemical changes in the DNA or histones. Scientists from the Max Planck Institute for Biophysical Chemistry in Göttingen have succeeded in creating an experimental system for testing the function of such chemical histone modifications and their influence on the organism.

Scientists identify molecular mechanism of muscle stem cell differentiation

Under normal circumstances, adult stem cells reside in muscle tissue, where they can differentiate into a number of different cell types. After an injury (or even a tough workout), muscles are inflamed as cells and molecules flood the area to control damage and begin repairs. When called upon to replace muscle tissue damaged by injury or genetic disease, some muscle stem cells differentiate, becoming new muscle cells, while others make more stem cells. At Sanford-Burnham Medical Research Institute (Sanford-Burnham), a team of scientists led by Pier Lorenzo Puri, M.D., Ph.D., recently uncovered the molecular messengers that translate inflammatory signals into the genetic changes that tell muscle stem cells to differentiate.

Researchers explain nano-topographical responsiveness of stem cells

Many scientists aspire to take control over the stem cell differentiation process, so that we can grow organs and implants perfectly matched to each patient in the future. Now research in the Journal of Tissue Engineering, published by SAGE-Hindawi, explains how engineering the topography on which stem cells grow, and the mechanical forces working on them, can be as powerful an agent for change as their chemical environment.

Researchers develop new technique to detect lung cancer

Early detection is critical for improving cancer survival rates. Yet, one of the deadliest cancers in the United States, lung cancer, is notoriously difficult to detect in its early stages.
