Mitochondrial DNA may have strong influence on cellular metabolism and disease susceptibility

About 1.5 billion years ago, tiny visitors came to live inside the cells that later evolved into all plant and animal life -- including humans.

UCI researchers accelerate and simplify directed evolution bioengineering technique

In a process known as directed evolution, scientists reengineer biomolecules to find ones that perform beneficial new functions. The field is revolutionizing drug development, chemical engineering and other applications, but to realize its promise involves painstaking and time-consuming laboratory work.

Scientists uncover hidden estrogen receptors in epithelial breast cells

Estrogens are hormones that play central roles in the development and the physiology of the breast, but also are involved in breast cancer. Like all hormones, estrogens exert their biological effects by binding to dedicated receptors in the target cell.

Cells retain memory of chemical signals to which they are exposed

We all start out as a clump of identical cells. As these cells divide and multiply, they gradually take on distinct identities, acquiring the traits necessary to form, for instance, muscle tissue, bone, or nerves. A recent study from Rockefeller scientists offers new insight into how these cellular identities are cultivated over the course of development.

Bfr organizes symposia for research on viruses and antimicrobial resistance in food chain

Against this background, the German Federal Institute for Risk Assessment is organising two symposia dealing with microbial risks in food in November 2018: "Food-associated viruses" on 7 November and "Antimicrobial resistance in the food chain" on 8/9 November.

Researchers develop powerful method to solve structures of small molecules

Small molecules -- from naturally occurring metabolites and hormones to synthetic medicines and pesticides -- can have big effects on living things. But for scientists to understand how the molecules work and how to design beneficial ones, they need to know the precise arrangement of atoms and chemical bonds.

ChromDesign project trains budding scientists in 3D architecture of genome

How does the three-dimensional architecture of our genes affect the differentiation of cells and development of diseases? This is the question behind the European Innovation Training Network "ChromDesign- Chromatin and Design".

Salk researchers solve genetic 'whodunnit' for cancer gene

Long thought to suppress cancer by slowing cellular metabolism, the protein complex AMPK also seemed to help some tumors grow, confounding researchers. Now, Salk Institute researchers have solved the long-standing mystery around why AMPK can both hinder and help cancer.

Scientists move closer to gonorrhea vaccine after large-scale proteomic study

In a study of proteins historic in its scope, researchers at Oregon State University have pushed closer both to a vaccine for gonorrhea and toward understanding why the bacteria that cause the disease are so good at fending off antimicrobial drugs.

Study explains how dermal fibroblasts age

With age, our tissues lose their function and capacity to regenerate after being damaged. A study published today in Cell by scientists at the Institute for Research in Biomedicine and the Centro Nacional de Análisis Genómico of the Center for Genomic Regulation explains how dermal fibroblasts age.

Changing Perspectives of the Triggers of Cell Division

Cell division is integral to understanding development, growth and disease states such as cancer. It has long been known that for replication, a complete new set of DNA and the formation of a septum, dividing the two cells, are necessary. New research changes perspectives of how these two processes influence the timing of cell division.

Small molecules designed to inhibit activity of enzymes in infectious diseases

A multidisciplinary study by the Computer Biochemistry Research Group of the Universitat Jaume I from Castellón, Spain, in collaboration with groups from universities from Canada and the United Kingdom, have designed small molecules that are able to bond with and inhibit the activity of enzymes in infectious diseases.

One type of Chlamydia protein manipulates human cells in two different ways

When Chlamydia trachomatis, the bacterium that causes one of the most common sexually transmitted infections worldwide, infects a human cell, it hijacks parts of the host to build protective layers around itself.

Researchers develop technique to disrupt communication between microorganisms

The World Health Organization considers Pseudomonas aeruginosa a germ requiring urgent action to prevent and control its spread. The bacteria can cause a variety of diseases from chronic lung infections to sepsis.

CWRH/UH researcher receives grant to study role of KLF2 factor in vascular-related disorders

Transcription factors are proteins that determine whether specific genes are transcribed or not by binding to DNA. In other words, they help turn genes "on" or "off."

New research to understand fundamental role of ubiquitin in cell death or survival

An effective regulation of programmed cell death is crucial for the correct development of embryos, a working innate immune system, and the prevention of cancer. How cells control the switch between cell survival and death, and which signaling pathways are involved, remain unclear.
