Patterns of mutation in cancer genes
In most cancers, the majority of the changes to the DNA (termed mutations), acquired during the disease process are inconsequential in terms of driving the cancer, however a few of the changes in a small set of
Cyagen Biosciences – Helping you choose the right animal model for your research
While many animal models are available “ off the shelf ” through various repositories and collaborations, generation of novel animal models has allowed for more effective studies, not limited by previously derived lines/ strains. Historically, researchers have
From parasitic microfungi towards the origins of Microsporidia
Microsporidia are unicellular eukaryotic parasites, infecting virtually all animals including humans. They are characterized by peculiar morphological and genetic features, which are the result of their extreme adaptation to the intracellular lifestyle. Interestingly, the infection apparatus in
G-quadruplexes: novel DNA structures controlling life from the beginning
The process by which a single cell, the zygote, becomes a fully formed organism has been a historic scientific enigma. Now we know that the information stored in the genes of the DNA is the responsible for
Unravel the key genes potentially related to high strength of cotton fiber by comparative phenotypic and genomic analyses
The demand of high strength of cotton fibers has been increased dramatically with the advent of modern high speed spinning technology for producing yarn. Cotton fiber is a gigantic single cell which consists of almost pure cellulose.
Protection from DNA-damage with the natural compound resveratrol
Resveratrol is currently known as a health-beneficial natural compound that is contained in grape skins, red wine, and other natural foods. Recent studies suggest that the compound could elongate the life spans of several organisms through a
Prox-1 and adipogenesis
Adipogenesis is the biological process that controls adipocytes differentiation and is one of the most well studied models of cellular differentiation. Adipose tissue is involved in the control of energy balance and especially in the study of
Allelic variations within genes coding for cytokines among Orang Asli in Peninsular Malaysia: New candidate genes for future disease studies
Cytokines are a set of low molecular weight proteins/glycoproteins secreted by almost all types of cells. They regulate cell growth, immune response and blood cell development in the bone marrow. Genetic variations in cytokine genes include single
Single nucleotide polymorphisms as genomic markers for high-throughput pharmacogenomic studies
DNA is a double strand molecule composed of nucleotide subunits, consisting of three components: a sugar, a phosphate group and one of four nitrogen-containing base, (Adenine, Cytosine, Guanine or Thymine). Among humans, DNA molecules are 99.9% identical.
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
