Scientists reveal underlying mechanism for formation and growth of epithelial tubes

A team of scientists from Singapore and France has revealed the underlying mechanism for the formation and growth of a fundamental type of tissue - epithelial tubes. Defects in the architecture of epithelial tubes lead to diseases such as cholestasis, atherosclerosis and polycystic kidney disease.

Scientists seek development of advanced tools to explore microbiomes

In October, an interdisciplinary group of scientists proposed forming a Unified Microbiome Initiative (UMI) to explore the world of microorganisms that are central to life on Earth and yet largely remain a mystery. An article in the journal ACS Nano describes the tools scientists will need to understand how microbes interact with each other and with us.

New GSA e-book provides detailed overviews of aging process across multiple organisms

A new e-book published by The Gerontological Society of America provides a primary resource for detailed overviews of the aging process across multiple organisms -- from microbes to humans. This seminal publication, "Molecular and Cellular Biology of Aging," is intended as a textbook for emerging scholars of all levels.

Researchers use large-scale computer modeling to show effects of confinement on cell macromolecules

Using large-scale computer modeling, researchers have shown the effects of confinement on macromolecules inside cells -- and taken the first steps toward simulating a living cell, a capability that could allow them to ask 'what-if' questions impossible to ask in real organisms.

Discovery could offer clues to how some viruses control expression of genetic material

Researchers at Case Western Reserve University and the University of Michigan have produced the first image of an important human protein as it binds with ribonucleic acid (RNA), a discovery that could offer clues to how some viruses, including HIV, control expression of their genetic material.

First computational method based on evolutionary principles developed to predict protein dynamics

Researchers from the Structural Biology Computational Group of the Spanish National Cancer Research Centre, led by Alfonso Valencia, in collaboration with a group headed by Francesco Gervasio at the University College London (UK), have developed the first computational method based on evolutionary principles to predict protein dynamics, which explains the changes in the shape or dimensional structure that they experience in order to interact with other compounds or speed up chemical reactions.

Novel chemical virus can cross double lipid layer surrounding cells to release drugs

Viruses are able to redirect the functioning of cells in order to infect them. Inspired by their mode of action, scientists from the CNRS and Université de Strasbourg have designed a "chemical virus" that can cross the double lipid layer that surrounds cells, and then disintegrate in the intracellular medium in order to release active compounds.

Symic receives $1.5M NIH Phase II SBIR grant to develop AVF therapeutic candidate

Platform therapeutic company Symic Biomedical, Inc. announced today that it has received a $1.5M Phase II SBIR grant from the National Institutes of Health to further develop its therapeutic agent to reduce arteriovenous fistula (AVF) failures, a significant unmet clinical need in end stage renal disease (ESRD) patients undergoing hemodialysis.

Study opens up new line of research into origin of digestive diseases

There are numerous studies related to the absorption of nutrients from the stomach since understanding what happens in our digestive system is crucial, for example, in order to be able to avoid in the future some of the diseases that affect part of the population to a lesser or greater extent.

Applying NMR to biological problems: an interview with Professor Arthur Palmer

Our current focus is on areas in protein folding, molecular recognition by proteins and also enzyme catalysis. NMR spin relaxation is one of the very powerful techniques in NMR for studying conformational dynamics in proteins or chemical kinetic processes.

RAB3GAP complex plays important role in autophagy

Neurodegenerative disorders such as Alzheimer's disease are typically characterized by protein deposits in the brain. These are comprised of defective, insoluble proteins which no longer fulfill their function and which cells are unable to break down. The work group headed by Professor Christian Behl of the Institute of Pathobiochemistry of the University Medical Center of Johannes Gutenberg University Mainz has determined the RAB3GAP complex as a novel factor that influences the efficient degradation of proteins.
