UCSF study reveals molecular timing mechanism of stem cells

UC San Francisco researchers have for the first time developed a method to precisely control embryonic stem cell differentiation with beams of light, enabling them to be transformed into neurons in response to a precise external cue.

BET inhibitors can cause molecular changes in neurons, lead to memory loss in mice

Cancer researchers are constantly in search of more-effective and less-toxic approaches to stopping the disease, and have recently launched clinical trials testing a new class of drugs called BET inhibitors. These therapies act on a group of proteins that help regulate the expression of many genes, some of which play a role in cancer.

PHD1 inhibition may have therapeutic potential for colorectal cancer

Scientists at VIB and KU Leuven have shown that blocking the PHD1 oxygen sensor hinders the activation of p53, a transcription factor that aids colorectal cancer (CRC) cells in repairing themselves and thus resisting chemotherapy. Chemotherapy resistance remains a major clinical issue in the treatment of CRC. These findings indicate that PHD1 inhibition may have valuable therapeutic potential. The study was published in the leading medical journal EMBO Molecular Medicine, which features molecular biology-driven research.

Researchers elucidate mechanism that induces skeletal muscle atrophy in patients with congestive heart failure

It is a paradox: Patients with advanced congestive heart failure lose skeletal muscle mass, but their heart muscles become enlarged to provide the body with an adequate supply of blood and thus with oxygen. It has long been known that the protein angiotensin II plays a villainous role in this process, but the exact mechanism has remained unclear.

New study reveals role of hydrogen sulfide gas in autoimmune disease

The immune system not only responds to infections and other potentially problematic abnormalities in the body, it also contains a built-in brake in the form of regulatory T cells, or Tregs. Tregs ensure that inflammatory responses don't get out of hand and do damage. In autoimmune diseases, sometimes these Treg cells don't act as they should.

Scientists decipher new molecular signaling path that prompts protein degradation in muscle

Patients in advanced states of myocardial insufficiency generally lose their muscle mass and muscle strength. Indeed a fact that until now has negatively impacted the clinical course of the disease and that has resulted in poor prognoses for patients. Such pathological muscle loss impacts the skeletal muscles in particular.

Sigma 1 receptor appears to play vital role in supporting the retina

A receptor that is already a target for treating neurodegenerative disease also appears to play a key role in supporting the retina, scientists report.

New technology advances genome engineering

In his mind, Basil Hubbard can already picture a new world of therapeutic treatments for millions of patients just over the horizon. It's a future in which diseases like muscular dystrophy, cystic fibrosis and many others are treated permanently through the science of genome engineering.

CSN6 protein linked to poor survival among patients with colorectal cancer

A protein called CSN6 has been found to be correlated with poor survival among patients with colorectal cancer, according to a study at The University of Texas MD Anderson Cancer Center.

Researchers identify genome-organizing mechanism that transmits vital genetic materials during mitosis

Chromosomes are responsible for carrying our genes and essentially protecting the information that helps ensure normal, healthy growth, with vital instructions being passed on from cell to cell by a process known as mitosis. While this copying mechanism has been well understood for decades, scientists have been unable to describe exactly how genetic information is protected and properly segregated as mitosis is happening.

Researchers develop new technology to track DNA-protein binding in live cells

Researchers have developed a new technology that precisely marks where groups of regulatory proteins called transcription factors bind DNA in the nuclei of live cells.

NFIX protein drives NSC differentiation toward oligodendrocytes

An international team of researchers has shown that NFIX, a protein that regulates neuronal stem cell activity (NSC), also has a role in driving NSC differentiation toward oligodendrocytes, a type of glial cell. These cells produce the myelin that surrounds and protects neurons.

Lund University researchers discovered 'main switch' that regulates cell invaginations

Lack of microinvaginations in the cell membrane, caveolae, can cause serious diseases such as lipodystrophy and muscular dystrophy. Researchers at Lund University in Sweden have now discovered a "main switch" that regulates the formation of these invaginations.

Research: Critical aspects of human genome's regulatory program encoded by genomic sequence elements

Since the classical studies of Jacob and Monod in the early 1960s, it has been evident that genome sequences contain not only blueprints for genes and the proteins that they encode, but also the instructions for a coordinated regulatory program that governs when, where and to what extent these genes and proteins are expressed.

BrightFocus announces recipients of 2015 research program grants

BrightFocus Foundation, which funds research worldwide on Alzheimer's disease, glaucoma, and macular degeneration, today announced that its 2015 research program grants have been awarded to 58 scientists in 20 states and 7 foreign countries. Part of an $11 million research investment, the grants reflect the largest annual research funding in the foundation's history.

Stress responder plays critical, early step in repairing DNA damage

DNA damage increases the risk of cancer, and researchers have found that a protein, known to rally when cells get stressed, plays a critical, early step in its repair.

Reducing incorrect gene expression can extend lifespan of cells

Working with yeast and worms, researchers found that incorrect gene expression is a hallmark of aged cells and that reducing such "noise" extends lifespan in these organisms. The team published their findings this month in Genes & Development.

Study focuses on regulation of neuronal plasticity

A team of scientists has linked changes in the structure of a handful of central brain neurons to understanding how animals adjust to changing seasons. Its findings enhance our understanding of the mechanisms vital to the regulation of our circadian system, or internal clock.

Researchers uncover new mechanism that p53 protein uses to trigger cell death

Researchers have identified a new mechanism that the tumor suppressor protein p53 uses to trigger cell death via apoptosis and have shown how the process could be harnessed to kill cancer cells. St. Jude Children's Research Hospital scientists led the study, which appears today in the scientific journal Molecular Cell.

Researchers uncover master regulators that govern the fate of TFH cells

Follicular helper Tcells (TFH cells), a rare type of immune cell that is essential for inducing a strong and lasting antibody response to viruses and other microbes, have garnered intense interest in recent years but the molecular signals that drive their differentiation had remained unclear.
