STAT3 transcription factor remains in the axon of nerve cells to help prevent neurodegeneration

A study in The Journal of Cell Biology shows how a transcription factor called STAT3 remains in the axon of nerve cells to help prevent neurodegeneration. The findings could pave the way for future drug therapies to slow nerve damage in patients with neurodegenerative diseases.

Four transcription factor genes control processes related to heart and head muscle formation

A group of researchers in Israel, the United States and other nations have made important advances in the rapidly-expanding field of "regenerative medicine," outlining for the first time connections in genetic regulation that normally prevent birth defects in heart and facial muscles.

Researchers zero in on process by which stem cells maintain proper undifferentiated state

The ability of embryonic stem cells to differentiate into different types of cells with different functions is regulated and maintained by a complex series of chemical interactions, which are not well understood. Learning more about this process could prove useful for stem cell-based therapies down the road. New research from a team led by Carnegie's Yixian Zheng zeroes in on the process by which stem cells maintain their proper undifferentiated state.

Idea of nuclear reprogramming holds promise for repairing damaged tissue

The idea of taking a mature cell and removing its identity (nuclear reprogramming) so that it can then become any kind of cell, holds great promise for repairing damaged tissue or replacing bone marrow after chemotherapy.

Scientists identify mechanism via Top2b enzyme that drives doxorubicin-induced heart damage

Doxorubicin, a 50-year-old chemotherapy drug still in widespread use against a variety of cancers, has long been known to destroy heart tissue, as well as tumors, in some patients.

Study identifies genetic variations as predictors of prostate cancer-related fatigue

Researchers at Moffitt Cancer Center and the University of South Florida have found that men with prostate cancer who receive androgen deprivation therapy may predictably suffer from fatigue if they have single nucleotide polymorphisms in three pro-inflammatory genes. The discovery highlights the importance of personalized medicine, in which therapies are tailored to a patient's genetic profile.

Researchers identify genes that control regeneration of the intestine in planarian flatworms

Researchers report in the journal Developmental Cell that they have identified genes that control growth and regeneration of the intestine in the freshwater planarian Schmidtea mediterranea.

Researchers identify new means to eradicate malaria infections

Researchers have identified a new means to eradicate malaria infections by rapidly killing the blood-borne Plasmodium parasites that cause the disease.

Study confirms Elf5 protein as tumor suppressor of breast cancer

A protein that is necessary for lactation in mammals inhibits the critical cellular transition that is an early indicator of breast cancer and metastasis, according to research conducted at the University at Buffalo and Princeton University and highlighted as the cover paper in November issue of Nature Cell Biology.

UNM Cancer Center scientist to continue histone modification study

While every one of our cells contains all of our genetic information, each type of cell uses only specific parts of that information to make its proteins. Uncovering more about the mechanism that directs which particular pieces of genetic information the cell uses is the research focus of Mary Ann Osley, PhD, University of New Mexico Professor of Molecular Genetics and Microbiology and Co-Leader of the Cancer Biology and Biotechnology Program at the UNM Cancer Center.

TSRI scientists to study structural rules that govern nuclear receptors

A consortium of scientists from both campuses of The Scripps Research Institute (TSRI) has been awarded $2.7 million from the National Institute of General Medical Sciences of the National Institutes of Health to study the structural rules that govern a large superfamily of proteins that help regulate critical functions such as reproduction, development and metabolism.

Vascular cell generation could be used to treat vascular disorders

A study in mice has shown that large numbers of vascular endothelial cells can be generated from human amniotic fluid-derived cells.

Reprogrammed vascular endothelial cells from ACs shows promise against vascular disorders

A new approach for generating large numbers of circulatory system cells, known as vascular endothelial cells (VECs), from human amniotic-fluid-derived cells (ACs) is reported in a study published by Cell Press October 18th in the journal Cell. The strategy, which shows promise in mice, opens the door to establishing a vast inventory of VECs for promoting organ regeneration and treating diverse vascular disorders.

Reprogrammed endothelial cells for treatment of vascular disorders

A research team at Weill Cornell Medical College has discovered a way to utilize diagnostic prenatal amniocentesis cells, reprogramming them into abundant and stable endothelial cells capable of regenerating damaged blood vessels and repairing injured organs.

Weill Cornell Medical College researcher wins 2012 William B. Coley Award

Dr. Laurie H. Glimcher, the Stephen and Suzanne Weiss Dean of Weill Cornell Medical College and provost for medical affairs of Cornell University, is a winner of the 2012 William B. Coley Award for Distinguished Research in Basic Immunology from the Cancer Research Institute for her outstanding achievements in immunology and cancer research.

New book focuses on Wnt signaling

Wnt proteins are signaling molecules that play critical roles during embryonic development and in the regeneration of adult tissues. They bind to Frizzled and LRP family receptors on the cell surface, triggering a series of events that cause beta-catenin to enter the nucleus and activate transcription factors that control cell fate and cell proliferation. Mutations in components of the Wnt pathway lead to developmental defects and are common in cancer.

Study finds novel function of non-protein coding RNA

While studying Parkinson's disease, an international research group made a discovery which can improve industrial protein synthesis for therapeutic use. They managed to understand a novel function of non-protein coding RNA: the protein synthesis activity of coding genes can be enhanced by the activity of the non-coding one called "antisense."

Researchers identify critical mechanisms of epigenetic cell programming

A team of researchers at the IRCM, supervised by Dr. Jacques Drouin, reprogrammed the identity of cells in the pituitary gland and identified critical mechanisms of epigenetic cell programming.

Scientists resolve new molecular circuit controlling cellular metabolism

Cancer, diabetes, and excess body weight have one thing in common: they alter cellular metabolism. Scientists from the Max Planck Institute of Immunobiology and Epigenetics in Freiburg and the Medical University of Vienna together with an international research team have jointly resolved a new molecular circuit controlling cellular metabolism.
