Energy intensive hub regions of the brain

In this work, we analyzed a massive database of brain connectivity data from the Allen Mouse Brain Connectivity Atlas, which contains data from experiments where researchers inject viral tracers into different regions of the mouse brain. The

How does aspirin inhibit melanin synthesis?

Non-steroidal anti-inflammatory drugs (NSAIDs) are known to act by directly suppressing the activity of cyclooxygenase, the key enzyme catalyzing the biosynthesis of prostaglandin, which induces inflammation. Therefore, NSAIDs are usually used for treating pain, inflammation, and fever.

A natural transgene may help plants to adapt to local conditions

Transgenes are genes that have moved from a donor to a recipient organism via a process known as horizontal gene transfer (HGT), in the absence of sexual reproduction. The genetic modification of crop species involves the deliberate

Another prince awakened Sleeping Beauty?

Tumor suppressor genes are one of the body’s defenses against uncontrolled growth of tumor cells. When these genes are ‘silenced,’ or prevented from doing their work, the abnormal cells grow unchecked, usually with fatal consequences to the

Sequence of the plant beneficial biocontrol agent Pseudomonas fluorescens DSM 8569

Pseudomonas represents an abundant bacterial group that can live in the soil. In this habitat many organisms like fungi, bacteria, plants or insects live together, often intensively interacting in close communities. The composition of these communities is

Novel presenilin 1 mutation in familial late-onset Alzheimer’s disease

Alzheimer’s disease (AD) is a progressive dementia, affecting over 20 million people worldwide, mainly adult subjects in advanced age characterized by loss of neurons and the presence of amyloid plaques in the brain. Several families have been

The exploration of gene expression in Atlantic bluefin tuna

Atlantic bluefin tuna (Thunus thynnus), the largest of the tuna species, is migratory top predator inhabiting the North Atlantic Ocean and the Mediterranean Sea. Extremely well adapted to life in open waters, they are able to traverse

PACAP expression induced in neuropathic pain is controlled by a splicing of REST/NRSF

Neuropathic pain (NP) is caused by the damage of the nervous system and one of the most common types of intractable pain. It is often severe, persistent, and refractory to available therapies. Although various analgesic has been

Understanding conifer responses to environmental changes

Conifers are a group of ancient plants that include tree species of great ecological and economical relevance. Inside this group, we can found trees such as pines, cedars, firs, spruces or cypresses. Coniferous forests dominate vast regions

Going my way? A tale of enzyme recruitment and activation

Protein synthesis is an energetically costly cellular process, in part due to the metabolic requirements of ribosome assembly and gene-specific messenger RNA (mRNA) production.  Consequently, biosynthetic flux through the protein translation pathway is tightly regulated while translational

G protein signaling: a major culprit of essential hypertension

Blood pressure (BP) is the driving force that distributes the blood to the organs of the body according to their instantanous needs. It may be increased by pressor agents acting on the heart, vessels, and blood volume,

Gene therapy: a promising candidate for cystic fibrosis treatment

An improved gene therapy treatment can cure mice with cystic fibrosis (CF). Cell cultures from CF patients, too, respond well to the treatment. Those are the encouraging results of a study presented by the Laboratory for Molecular

Genome sequence of the natural antagonist Pseudomonas fluorescens 2-79 against fungal plant diseases

In agriculture we have to deal with a huge variety of diseases caused by phytopathogenic bacteria, fungi or insects for instance. Many of these plant pathogens live in the soil and attack the respective cultivar at the

Why do people undergo genetic testing – for personal benefits, for family, or for science and society?

Genetic testing is an important tool to detect gene mutations (e.g., BRCA1/2) that increase the risk of cancer, especially among those who are known to have higher chances of carrying these mutations such as Ashkenazi Jewish individuals.

Prader-Willi syndrome: most common genetic cause of life-threatening obesity

Prader-Willi syndrome (PWS) is a rare complex multisystem genetic disorder. It is recognized as the most common known genetic cause of obesity in humans which can be life-threatening, if not controlled. PWS affects about 1 in 15,000

Association of polymorphism gene with clinical variability in cystic fibrosis patients

Cystic fibrosis (CF) is an inherited disease, caused by a dysfunction (mutation) in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. This disease affects a numerous organs particularly the lungs and digestive system. CF is characterized by
