Childhood brain cancer (ETMR/ETANTR): an interview with Dr. Nada Jabado, Department of Pediatrics at McGill University

Embryonal tumours with multilayered rosettes (ETMR) are rare, deadly brain tumours that affect mainly children below the age of 4 years. There are 300 cases reported but probably there are many more as this tumour is often misdiagnosed.

RNA sequencing unlocks bipolar secrets

An RNA sequencing study of patients with bipolar disorder has shown altered expression of genes and transcripts, including those involved in neuroplasticity and circadian rhythms.

Cell transplantation, gene therapy combination to open new therapeutic avenues for Alzheimer's disease

In a recent study published in the Neural Regeneration Research (Vol. 8, No. 33, 2013), Prof. Feng Li and team from Zhongshan School of Medicine, Sun Yat-sen University in China, synthesized a 19-nt oligonucleotide targeting BACE1, the key enzyme in amyloid beta protein (Aβ) production, and introduced it into the pSilenCircle vector to construct a short hairpin (shRNA) expression plasmid against the BACE1 gene.

Research: Human neural stem cells could improve blood flow in critical limb ischemia

New research has shown human neural stem cells could improve blood flow in critical limb ischemia through the growth of new vessels. Critical limb ischemia is a disease that severely obstructs arteries and reduces the blood flow to legs and feet. CLI remains an unmet clinical problem and with an ageing population and the rise in type II diabetes, the incidence of CLI is expected to increase.

Buyang Huanwu Decoction regulates neural stem cell behavior in ischemic brain

The traditional Chinese medicine Buyang Huanwu Decoction has been shown to improve the neurological function of patients with stroke.

Study suggests neural stem cells have tendency for malignant transformation

Although it is believed that glioma is derived from brain tumor stem cells, the source and molecular signal pathways of these cells are still unclear.

Study highlights new treatment options for neurodevelopmental disorders like TSC

Clemson University scientists are working to determine how neurons are generated, which is vital to providing treatment for neurological disorders like Tuberous Sclerosis Complex (TSC).

Researchers suggest new view of how stem cells may help repair brain following trauma

University of South Florida researchers have suggested a new view of how stem cells may help repair the brain following trauma. In a series of preclinical experiments, they report that transplanted cells appear to build a "biobridge" that links an uninjured brain site where new neural stem cells are born with the damaged region of the brain.

Stem cell therapy improves radiation-induced cognitive impairment

Patients receiving cranial irradiation treatment for brain cancer may find the treatment life-saving, but often suffer progressive and debilitating cognitive detriments, including spatial learning and memory deficits. The cognitive deficits are a contributing factor to the often significant adverse impacts on the surviving patients' quality of life after radiation therapy. In an effort to improve post-irradiation cognitive impairment, scientists at the University of California, Irvine, and colleagues at Neuralstem, Inc. (Rockville, MD), have transplanted fetal stem cells into laboratory animals with radiation-induced cognitive impairments and found that this led to a number of cognitive improvements.

Neural stem cells transplantation in tumor-bearing rats can hinder tumor cell growth

Neural stem cells transplanted into tumor-bearing rats can hinder tumor cell growth and prolife-ration; however, the mechanism remains unclear.

Researchers suggest neural stem cells may regenerate after anti-cancer treatment

Scientists have long believed that healthy brain cells, once damaged by radiation designed to kill brain tumors, cannot regenerate. But new Johns Hopkins research in mice suggests that neural stem cells, the body's source of new brain cells, are resistant to radiation, and can be roused from a hibernation-like state to reproduce and generate new cells able to migrate, replace injured cells and potentially restore lost function.

Researchers explore potential of neural stem cells to repair brain damage

Scientists have long believed that healthy brain cells, once damaged by radiation designed to kill brain tumors, cannot regenerate. But new Johns Hopkins research in mice suggests that neural stem cells, the body’s source of new brain cells, are resistant to radiation, and can be roused from a hibernation-like state to reproduce and generate new cells able to migrate, replace injured cells and potentially restore lost function.

Understanding the movement of neurons sheds light on how cancer cells invade health tissues

The invasion of brain-tumor cells into surrounding tissue requires the same protein molecule that neurons need to migrate into position as they differentiate and mature, according to new research from the University of Illinois at Chicago College of Medicine and published August 7 in the online journal PLOS ONE.

Brain tumor cells in arrested development contribute to cell variety that protects cancer

A program that pushes immature cells to grow up and fulfill their destiny as useful, dedicated cells is short-circuited in the most common and deadly form of brain tumor, scientists at The University of Texas MD Anderson Cancer Center report this week in the Early Edition of the Proceedings of the National Academy of Sciences.

Nanofiber scaffolds regulate apoptosis, proliferation in neural stem cells by altering gene expression

The surface characteristics of nanoscaffolds made by nanotechnology are more similar to the three-dimensional topological structure of the extracellular matrix and the effects on the biological behaviors of cells and tissue repair are more beneficial.

Scientists focus on the role of mutated adult neural stem cells play in human diseases

CHARGE syndrome* is a severe developmental disorder affecting multiple organs. It affects 1 in 8500 newborns worldwide. The majority of patients carry a mutation in a gene called CHD7. How this single mutation leads to the broad spectrum of characteristic CHARGE symptoms has been a mystery.

TSRI neuroscientists fill in significant gap in the understanding of how neurons mature

Neuroscientists at The Scripps Research Institute have filled in a significant gap in the scientific understanding of how neurons mature, pointing to a better understanding of some developmental brain disorders.

Stem cell patterns in flies offer potential applications for human biologists

A new study examining the brains of fruit flies reveals a novel stem cell mechanism that may help explain how neurons form in humans. A paper on the study by researchers at the University of Oregon appeared in the online version of the journal Nature in advance of the June 27 publication date.

Researchers find way to differentiate iPSCs into mature human neurons in the brain

Difficult-to-study diseases such as Alzheimer's, schizophrenia, and autism now can be probed more safely and effectively thanks to an innovative new method for obtaining mature brain cells called neurons from reprogrammed skin cells. According to Gong Chen, the Verne M. Willaman Chair in Life Sciences and professor of biology at Penn State University and the leader of the research team, "the most exciting part of this research is that it offers the promise of direct disease modeling, allowing for the creation, in a Petri dish, of mature human neurons that behave a lot like neurons that grow naturally in the human brain."
