Canine DNA study uncovers new genes linked to gastric cancer

Dogs share our homes, our habits and sometimes, our diseases. Gastric cancer is rare in dogs, but when it does strike, it closely resembles gastric cancer in humans: subtle clinical signs, comparable tumor subtypes, late-stage diagnosis and poor outcomes.

New compound infuzide shows promise against resistant bacterial infections

Antimicrobial resistance directly causes more than 1 million deaths every year and contributes to more than 35 million more, according to the World Health Organization. Staphylococcus aureus and Enterococcus sp., 2 gram-positive pathogens highly likely to develop resistance to known treatments, can cause dangerous hospital-acquired and community-acquired infections.

Scientists uncover how a single gene shaped the course of plague pandemic

Scientists have documented the way a single gene in the bacterium that causes bubonic plague, Yersinia pestis, allowed it to survive hundreds of years by adjusting its virulence and the length of time it took to kill its victims, but these forms of plague ultimately died out.

What drives insulin resistance? Proteomics reveals key pathways in human skeletal muscle

Identifying proteomic signatures of insulin resistance in fasting muscle offers insights for personalized type 2 diabetes therapies based on molecular profiles.

New discovery reveals how cohesin complex alters gene expression

Cohesin is a protein that forms a ring-shaped complex which wraps and alters the DNA molecule shape. It moves through the DNA and creates specific loops in the genetic material which determine the architecture of the genome and gene expression.

Genetic analysis shows leprosy was endemic in pre-colonial America

Long considered a disease brought to the Americas by European colonizers, leprosy may actually have a much older history on the American continent.

Advanced organoid model recreates complex liver architecture

The liver has a unique structure, especially at the level of individual cells. Hepatocytes, the main liver cells, release bile into tiny channels called bile canaliculi, which drain into the bile duct in the liver periportal region.

Salk researchers create detailed genetic atlas of cannabis to date

Cannabis has been a globally important crop for millennia. While best known today as marijuana for its psychoactive cannabinoid THC (tetrahydrocannabinol), historically, cannabis has been a cornerstone of human civilization, providing seed oil, textiles, and food for more than 10,000 years.

Necrosis may hold the key to unlocking longevity and space health solutions

The process of necrosis, a form of cell death, may represent one of the most promising ways to change the course of human aging, disease and even space travel, according to a new study from researchers at UCL, drug discovery company LinkGevity and the European Space Agency (ESA).
