Manipulating a specific gene from yeast could lead a new approach to combatting drug resistance

A recent study that shows manipulating and deleting a specific gene (AMN1) from yeast could provide a foundation for a new approach to combatting drug resistance when treating microbial infections or cancer.

New micro-protein supports cell division and proliferation during nutrient scarcity

Researchers from the University of Eastern Finland and the University of Montreal (Canada) have discovered that a micro-protein, which they named Nrs1, supports cell division and proliferation when nutrients are scarce.

Researchers identify human BCAS3 and C16orf70 as novel autophagic proteins

Autophagy is an intracellular degradation process of cytosolic materials and damaged organelles. Researchers at Ubiquitin Project of TMIMS have been studying the molecular mechanism of mitophagy, the selective autophagy process to eliminate damaged mitochondria.

Biomarkers can predict how genetically identical cells behave differently under stress

A set of biomarkers not traditionally associated with cell fate can accurately predict how genetically identical cells behave differently under stress, according to a UT Southwestern study.

Study sheds new light on mechanisms of cohesin function involved in cancer and cardiac development

Ana Losada, from the Spanish National Cancer Research Centre (CNIO), is the scientist who identified cohesin in vertebrates, a protein that is essential in cell division.

Researchers unravel key mechanisms behind the mysteries of aging

Molecular biologists and bioengineers at the University of California San Diego have unraveled key mechanisms behind the mysteries of aging. They isolated two distinct paths that cells travel during aging and engineered a new way to genetically program these processes to extend lifespan.

Study sheds light on homologous recombination of DNA strands

As chromosomes go, X and Y make an unlikely pair. The X is large and contains thousands of genes critical for life. The Y, by contrast, is little more than a nub.

Study elucidates how essential amino acid in humans acts as growth signal for cells

A recent study from the Laxman lab elucidates how a small metabolite and amino acid, methionine, acts as a growth signal for cells, by setting into motion a metabolic program for cell proliferation.

Study: Atg2 tethers pre-autophagosomal membrane to endoplasmic reticulum during autophagosome formation

Postdoctoral Researcher Tetsuya Kotani, Associate Professor Hitoshi Nakatogawa, Honorary Professor Yoshinori Ohsumi and colleagues at Tokyo Institute of Technology have analyzed the Atg protein Atg2, whose function had been completely unknown, and have discovered that Atg2 tethers the pre-autophagosomal membrane to the endoplasmic reticulum during autophagosome formation.

Study links cell size with commitment to division

How does a cell know when to divide? We know that hundreds of genes contribute to a wave of activity linked to cell division, but to generate that wave new research shows that cells must first grow large enough to produce four key proteins in adequate amounts.

Researchers discover glutamine-dependent activation of cell growth and autophagy

The human body consists of about 35 trillion cells, so it could be said that overall body growth is the growth of individual cells.

Genetic diversity plays major role in evolution of drug resistance

Researchers have shown that genetic diversity plays a key role in enabling drug resistance to evolve. Scientists at the Wellcome Trust Sanger Institute and the Institute for Research on Cancer and Ageing of Nice in France, show that high genetic diversity can prime new mutations that cause drug resistance.

Understanding molecular mechanisms and metabolic pathways of yeast for drug discovery

My research uses budding yeast as a tool for synthetic biology, and also in chemical and functional genomic applications. We are interested in understanding molecular mechanisms and metabolic pathways of yeast for drug discovery.

Cancer cells may lose copies of ribosomal DNA to enable faster proliferation, study shows

Research from the Stowers Institute provides evidence suggesting that cancer cells might streamline their genomes in order to proliferate more easily.

Researchers reveal molecular mechanism of autophagy initiation

Researchers revealed that Atg13 links autophagy initiation factors to each other using a string-like conformation, thereby promoting the association of diverse elements of the autophagy initiation machinery, initiating autophagosome formation through the recruitment of Atg9 vesicles and phosphorylation of various Atg factors.

Continuous errors in damaged DNA repair may lead to tumor formation

A group of researchers at Osaka University found that if DNA damage response (DDR) does not work when DNA is damaged by radiation, proteins which should be removed remain instead, and a loss of genetic information can be incited, which, when repaired incorrectly, will lead to the tumor formation.

Two studies shed new light on nature of tandem DNA repeat arrays

A pair of studies by a team of scientists has shed new light on the nature of a particular type of DNA sequences—tandem DNA repeat arrays—that play important roles in transcription control, genome organization, and development.

FSU investigator solves cell division mystery

In the second part of his lab's recent one-two punch, Florida State University researcher Daniel Kaplan said he has solved a cell division mystery in a way that will intrigue the makers of cancer-fighting drugs.

Reducing incorrect gene expression can extend lifespan of cells

Working with yeast and worms, researchers found that incorrect gene expression is a hallmark of aged cells and that reducing such "noise" extends lifespan in these organisms. The team published their findings this month in Genes & Development.

Researchers discover how and where chromosome fragile sites occur in human DNA

Using a novel method they developed to map chromosome breaks in a model organism, the budding yeast, Wenyi Feng, Ph.D., of Upstate Medical University and her colleagues have discovered new information as to how and where chromosome fragile sites can occur in human DNA. These sites are frequently observed in cancer cells and are responsible for causing genomic rearrangements.
