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.

Mutant p53 protein 'tackles' DNA guardian to drive tumor development

Melbourne scientists have discovered how tumor development is driven by mutations in the most important gene in preventing cancer, p53.

Tracking down microRNA candidates linked to disease

What started as Ninad Oak's side project turned out into something much larger, his doctorate thesis. "The project started as my qualifying exam that I proposed at the end of my first year of graduate school," said Oak, a graduate student in molecular and human genetics in Dr. Sharon E. Plon's lab. "This was an off topic qualifying exam at the time, meaning the lab had not worked on this topic before."

Genetic inhibition of SARM1 prevents axonal degeneration in nervous systems

Disarm Therapeutics, a biotechnology company creating a new class of disease-modifying therapeutics for patients with axonal degeneration, a central driver of neurological disease, today announced data demonstrating that genetic inhibition of SARM1 prevents axonal degeneration in the central, ocular and peripheral nervous systems.

PPM1D gene confers a survival advantage to stem cells after chemotherapy

Chemotherapy has been associated with increased risk of leukemia years after the treatment, but what leads to that association is not clear.

UCV researchers discover the influence of exosomes on age-related macular degeneration

Researchers of the Neurobiology and Neurophysiology team of the Medicine Faculty at Valencia Catholic University, headed by Jorge Bacia, have discovered that exosomes - microscopic extracellular vesicles that are released by all cells - from the retinal pigment epithelium lead to cases of neovascularization, a finding which could be closely related to similar processes in age-related macular degeneration.

U.S. immigration changes a person's gut microbiome

Researchers at the University of Minnesota and the Somali, Latino, and Hmong Partnership for Health and Wellness have new evidence that the gut microbiota of immigrants and refugees rapidly Westernize after a person's arrival in the United States.

New study upends conventional theories about fluid nature of cell membranes

If you want to understand how the cell membrane works, Adam Cohen says, look no further than your kitchen. Cohen, a Professor of Chemistry and Chemical Biology and of Physics, is the lead author of a new study that upends the conventional theories about the fluid nature of cell membranes and how they react to tension.

CNIO researchers link MASTL protein to origin of thrombocytopenia

The Cell Division and Cancer Group of the Spanish National Cancer Research Centre has discovered that MASTL, the protein whose function in the organism has not yet been sufficiently investigated, plays an important role in controlling the cytoskeleton, the structure that gives shape to the cells, and enables their mobility and capacity for grouping.

Researchers discover how protein pair regulates cellular calcium signals

All mammalian cells need a ready supply of calcium ions to execute functions as diverse as neurotransmission, muscle contraction, hormone release, or immune responses. So fundamental is this requirement that cells protect themselves from disaster by storing calcium in a network of intracellular cisterns called the endoplasmic reticulum, or ER.

Genetic defect linked to ALS causes sugar-starved cells to overproduce lipids

A genetic defect tied to a variety of neurodegenerative diseases and mental illnesses changes how cells starved of sugar metabolize fatty compounds known as lipids, a new study led by researchers from the Johns Hopkins Bloomberg School of Public Health shows.
