Study shows how astrocytes control new neuron generation in the brain

Researchers from the Laboratory of astrocyte biology and CNS regeneration headed by Prof. Milos Pekny just published a research article in a prestigious journal Stem Cells on the molecular mechanism that controls generation of new neurons in the brain.

Scientists develop reliable method to convert adult blood cells into iPSCs

Johns Hopkins scientists have developed a reliable method to turn the clock back on blood cells, restoring them to a primitive stem cell state from which they can then develop into any other type of cell in the body.

Changes in DNA methylation might be linked to evolution of humans' vulnerability to diseases

Chimpanzees rarely get cancer, or a variety of other diseases that commonly arise in humans, but their genomic DNA sequence is nearly identical to ours. So, what's their secret? Researchers reporting in the September issue of the American Journal of Human Genetics, a Cell Press journal, have found that differences in certain DNA modifications, called methylation, might play a role.

Gibbons use same vocal techniques as professional soprano singers

Have you ever heard an opera singing ape? Researchers in Japan have discovered that singing gibbons use the same vocal techniques as professional soprano singers. The study, published in the American Journal of Physical Anthropology, explains how recording gibbons singing under the influence of helium gas reveals a physiological similarity to human voices.

Researchers deciphered function of claudin-10 gene in the kidney

Sodium chloride, better known as salt, is vital for the organism, and the kidneys play a crucial role in the regulation of sodium balance. However, the underlying mechanisms of sodium balance are not yet completely understood.

The Wistar Institute, MSKCC partner to publish first annotated atlas of Epstein-Barr virus genome

Researchers from The Wistar Institute and Memorial Sloan-Kettering Cancer Center (MSKCC) have teamed to publish the first annotated atlas of the Epstein-Barr virus genome, creating the most comprehensive study of how the viral genome interacts with its human host during a latent infection. Epstein-Barr virus (EBV), which is thought to be responsible for one percent of all human cancers, establishes a latent infection in nearly 100 percent of infected adult humans.

Scripps Research Institute scientist to uncover workings of the immune system

A team led by a scientist at The Scripps Research Institute has received a $22.5 million, five-year project renewal from the National Institutes of Health to uncover the workings of the immune system.

New method can differentiate between breast cancer patients with good and poor prognosis

It is now possible to identify aggressive breast cancers by interpreting the mathematical patterns in the cancer genome. Researchers at the University of Oslo, Norway (UiO) have developed a completely new method for differentiating between breast cancer patients with high and low risks of dying from the illness.

LXRbeta may play a role in prevention and treatment of Parkinson's

Scientists at the University of Houston (UH) have discovered what may possibly be a key ingredient in the fight against Parkinson's disease.

GlcNAc plays a key role in keeping cancerous monsters ‘fed’

Behaving something like ravenous monsters, tumors need plentiful supplies of cellular building blocks such as amino acids and nucleotides in order to keep growing at a rapid pace and survive under harsh conditions. How such tumors meet these burgeoning demands has not been fully understood.

PHF20 transcriptional factor plays a unique role in regulating p53

Researchers at Moffitt Cancer Center and colleagues have identified PHF20, a novel transcriptional factor, and clarified its role in maintaining the stability and transcription of p53, a gene that allows for both normal cell growth and tumor suppression. PHF20, the researchers found, plays a previously unknown and unique role in regulating p53.

Study helps explain how human airways clear sticky mucus out of the lungs

A runny nose and a wet cough caused by a cold or an allergy may not feel very good. But human airways rely on sticky mucus to expel foreign matter, including toxic and infectious agents, from the body.

Influenza virus can change microRNA expression to control immune responses in human lung cells

When you are hit with the flu, you know it immediately -- fever, chills, sore throat, aching muscles, fatigue. This is your body mounting an immune response to the invading virus. But less is known about what is happening on the molecular level.

MOZ protein could explain variations in severity of DiGeorge syndrome

The discovery of a 'switch' that modifies a gene known to be essential for normal heart development could explain variations in the severity of birth defects in children with DiGeorge syndrome.

NCKU research team identifies Au nanorod complex for cancer therapy

A National Cheng Kung University (NCKU) research team has discovered Near-Infrared Light-Responsive oligonucleotide-gated Au nanoensembles (Au nanorod complex), a potent new anti-cancer complex that is seen as a promising targeted therapy for curing cancer.

New UCLA study pinpoints unique human patterns of gene activity in the brain

Human and chimp brains look anatomically similar because both evolved from the same ancestor millions of years ago. But where does the chimp brain end and the human brain begin? A new UCLA study pinpoints uniquely human patterns of gene activity in the brain that could shed light on how we evolved differently than our closest relative.

Researcher describes structure and function of tuberculosis efflux pump regulator

Edward Yu took note of the facts - nearly 2 million deaths each year, 9 million infected each year, developments of multidrug-resistant, extensively drug-resistant and now totally drug-resistant strains - and decided to shift his research focus to tuberculosis.

Microtubule stiffening worsens skeletal muscle degeneration in Duchenne muscular dystrophy

University of Maryland (UM) researchers and collaborators report in the journal Science Signaling that skeletal muscle degeneration in Duchenne muscular dystrophy (DMD) is worsened by stiffening of the microtubule cytoskeleton that provides structure inside muscle cells.
