Scientists uncover a moving target in small cell lung tumors

Lung cancers account for approximately 25 percent of all cancer deaths. Even among those who do not smoke, 1 in 15 men and 1 in 17 women are expected to develop lung cancer in their lifetime, according to the American Cancer Society.

Study demonstrates the role of p53 gene in cell cycle regulation and apoptosis

The p53 gene is crucial in cell biology and thus cell replacement therapy. The function of this gene is to control the cell cycle and stop tumor formation.

Study may help develop medical implants for diabetic patients

For the first time, a research team led by Martin Fussenegger, a professor at ETH Zurich, has successfully used electric current to directly manipulate gene expression.

New insights into recombination of sex chromosomes during meiosis

As chromosomes go, X and Y make an unlikely pair. The X is large and contains thousands of genes critical for life.

gnomAD Consortium releases first set of discoveries on human genetic variation

For the last eight years, the Genome Aggregation Database Consortium (and its predecessor, the Exome Aggregation Consortium, or ExAC), has been working with geneticists around the world to compile and study more than 125,000 exomes and 15,000 whole genomes from populations around the world.

ADHD-associated genetic variants have reduced progressively in human lineage

According to a study published in the Scientific Reports journal, the frequency of genetic variants linked to attention-deficit/hyperactivity disorder (ADHD) has reduced progressively in the evolutionary human lineage from the Palaeolithic to the present day.

Chicken cells show promise for producing more effective human antibodies

Antibodies meant for potential drug applications can be produced quickly in chicken cells cultured in laboratories.

Warwick researchers discover how cells respond to fasting and activate autophagy

As modern life-styles and high-calorie diets drive the UK's obesity levels up, researchers from the University of Warwick have found how cells respond to fasting and activate the process called autophagy, which means a healthier lifestyle can be promoted to help people maintain a healthy body weight.

Study highlights crucial role of immune-system molecule in Huntington's disease

More than a decade before people with Huntington's disease show symptoms, they can exhibit abnormally high levels of an immune-system molecule called interleukin-6 (IL-6), which has led many researchers to suspect IL-6 of promoting the eventual neurological devastation associated with the genetic condition.

Study shows how ocean virus captures the metabolism of carbon-storing bacteria

Below the surface of the ocean, a virus is stealing the metabolism of the most abundant organism present on Earth. That might be attractive to those who breathe above the ocean’s surface.

Using CRISPR/Cas molecular scissors to recombine entire chromosomes

The CRISPR/Cas molecular scissors work like a fine surgical instrument and can be used to modify genetic information in plants.

New sequencing method helps map the spatial arrangement of DNA

A sequencing technique helps to map the spatial arrangement of DNA in the cell nucleus, revealing which regions of the genome are at greater risk of mutation.

Pre-existing genes can promote metastasis

Cancer can sometimes remain dormant, but it usually metastasizes and spreads to new sites in the body.

Bariatric surgery may change gene expression in fat tissue

Altered gene expression in fat tissue may help explain why individuals who have regained weight after weight loss surgery still experience benefits such as metabolic improvements and a reduced risk of type 2 diabetes.

New tool shows how microbes influence health and promote diseases

Scientists from the Quadram Institute and Earlham Institute have developed a unique tool that is helping them to translate the complex communication that takes place between the body and the microbiome.

Compounds in Brazilian shrub can reduce the virulence of antibiotic-resistant bacteria

Researchers have discovered that the Brazilian peppertree—an invasive, weedy shrub found in Florida—contains specific compounds that lower the virulence of Staphylococcus bacteria that are resistant to antibiotics.

Genetic 'memory' of ancestral homelands helps organisms adapt to environmental change

Organisms carry long-term "memories" of their ancestral homelands that help them adapt to environmental change, according to a new study that involved raising chickens on the Tibetan Plateau and an adjacent lowland site.

Researchers identify the smallest gene to study the evolution of metazoans

St Petersburg University researchers have successfully interpreted the Intoshia variabili gene, which happens to be the smallest representative of the parasite belonging to Orthonectida group.

Scientists develop novel model of liver cancer stem cells from normal iPSCs

Liver cancer is one of the deadliest cancers. It is insidious and does not present symptoms until it has progressed considerably, at which point, treatment options are limited and chances of survival are low. The most common type of liver cancer is hepatocellular carcinoma.
