Research reveals how mutant p53 enhances tumor metastasis

Scientists at The Wistar Institute have found a novel mechanism through which mutant p53 enhances metastasis by controlling tumor metabolism. The research, published online in Genes & Development, also revealed how this process is influenced by a naturally occurring p53 gene variant.

Repurposing leukemia drugs may be effective approach for treating metastatic melanoma patients

Data from a new study led by University of Kentucky Markey Cancer Center researchers shows that repurposing drugs used to treat leukemia has promise for preventing melanoma metastasis.

Combined analysis makes risk prediction for colorectal cancer more precise

If first-degree relatives are affected by colorectal cancer, this indicates a person's own elevated risk of developing bowel cancer. The same holds true for people who have large numbers of genetic risk markers in their genome.

New discovery could help understand and treat glaucoma

Researchers have discovered two distinct groups of short molecules that regulate gene expression in the eyes of people with two different forms of glaucoma.

Research provides new directions in understanding and fighting glaucoma

Two distinctive handfuls of short molecules that regulate gene expression have been found in the eye fluid of patients with two distinct types of vision degenerating glaucoma.

Scientists reveal new insights into mechanism of gene regulation by 'magic spot'

Using an innovative crystallization technique for studying three-dimensional structures of gene transcription machinery, an international team of researchers, led by scientists at Penn State, has revealed new insights into the long debated action of the "magic spot"--a molecule that controls gene expression in Eschericahia coli and many other bacteria when the bacteria are stressed.

New low-cost microfluidic device brings single-cell technology to bedside

Single-cell analysis holds enormous potential to study how individual cells influence disease and respond to treatment, but the lack of cost-effective and user-friendly instrumentation remains challenging.

Patients at risk of heart disease do not always understand genetic test results

University of Sydney researchers are raising concerns over the need for informed decision making for genetic testing after a study published today finds patients at risk of inherited heart disease do not always understand test results or the impact results will have on their life.

Genetic variants make Asians and Europeans more prone to severe dengue

As globalization and climate change spread tropical infectious diseases around the globe, not all populations have the same degree of susceptibility.

Child’s snacking patterns could be linked to genetics, study finds

Whether your child asks for crackers, cookies or veggies to snack on could be linked to genetics, according to new findings from the Guelph Family Health Study at the University of Guelph.

Asthmatics have lower degree of DNA methylation in certain immune cells

Children with asthma have epigenetic DNA changes in certain cells of their immune system, a major international study involving researchers at Karolinska Institutet shows. The finding, which is presented in The Lancet Respiratory Medicine, can one day lead to improved diagnostics and treatment.

Researchers describe important step toward gene therapy for patients with Sandhoff disease

Babies with the rare, deadly genetic disorder Sandhoff disease begin to miss developmental milestones just months after birth. Lacking muscle tone, they never learn to sit up, develop heads too large to lift and eventually suffer uncontrollable seizures. There is no cure.

Scientists decode molecular structure of healthy huntingtin protein

Mutations on a single gene, the huntingtin gene, are the cause of Huntington's disease. They lead to an incorrect form of the correspondent protein.

Study sheds light on biological mechanisms that drive rare pediatric neurogenetic disorders

Researchers studying a rare genetic disorder that causes severe, progressive neurological problems in childhood have discovered insights into biological mechanisms that drive the disease, along with early clues that an amino acid supplement might offer a targeted therapy.

Epigenetic changes due to normal aging process linked to cancer risk

Some scientists have hypothesized that tumor-promoting changes in cells during cancer development--particularly an epigenetic change involving DNA methylation--arise from rogue cells escaping a natural cell deterioration process called senescence.

Neuroscientists discover novel mechanism of action behind schizophrenia

An international team of researchers led by a Case Western Reserve University School of Medicine scientist has uncovered a novel mechanism in which a protein--neuregulin 3--controls how key neurotransmitters are released in the brain during schizophrenia.

Antibiotic-producing bacterium releases more metabolites than assumed

The bacterium Streptomyces chartreusis is an antibiotic-producing bacterium that releases more metabolites into the surrounding medium than scientists assumed based on the analysis of the genome. Many of the substances are likely released to mediate interactions with its environment.

Penn study sheds new light on immune cell identity

Almost all cells in the human body have identical DNA sequences, yet there are 200-plus cell types with different sizes, shapes, and chemical compositions. Determining what parts of the genome are read to make protein and which are silenced is orchestrated by proteins called transcription factors.

Researchers discover five new genetic changes that may increase pancreatic cancer risk

In what is believed to be the largest pancreatic cancer genome-wide association study to date, researchers at the Johns Hopkins Kimmel Cancer Center and the National Cancer Institute, and collaborators from over 80 other institutions worldwide discovered changes to five new regions in the human genome that may increase the risk of pancreatic cancer.

Researchers create minuscule, light-powered wires to modify electrical signaling between neurons

The human brain largely remains a black box: How the network of fast-moving electrical signals turns into thought, movement and disease remains poorly understood. But it is electrical, so it can be hacked--the question is finding a precise, easy way to manipulate electrical signaling between neurons.
