Researchers unravel 3D structure of key molecular target for cancer treatment

Columbia University scientists, in collaboration with researchers from Nimbus Therapeutics, have demystified a metabolic enzyme that could be the next major molecular target in cancer treatment.

Gut microbiome signatures in colorectal cancer transcend culture and diet

Patients with colorectal cancer have the same consistent changes in the gut bacteria across continents, cultures, and diets -- a team of international researchers, from University of Copenhagen among others, find in a new study.

Study evaluates effects of unpaired 1 gene overexpression on lifespan in flies

Alexey Moskalev, Ph.D., Head of the Laboratory of Geroprotective and Radioprotective technologies, and co-authors from the Institute of biology of Komi Science Center of RAS announce the publication of a scientific article titled "Effects of unpaired 1 gene overexpression on the lifespan of Drosophila melanogaster" in BMC Systems Biology - an open access journal publishing original peer-reviewed research articles in experimental and theoretical aspects of the function of biological systems at the molecular, cellular or organismal level.

Analysis of tumor microenvironment to improve effectiveness of preclinical trials

It was shown that co-culturing HeLa adenocarcinoma cells, peripheral blood mononuclear cells, and mesenchymal stromal cells results in changes in the proliferative activity of the peripheral blood mononuclear cells and mesenchymal stromal cell populations.

Molecular biologists develop pipeline to create and screen new lantibiotic peptides

Nature has provided us with lots of antimicrobials. However, given the rapid increase of antimicrobial resistance, there is a need for the development of new-to-nature antibiotics. Lantibiotics are an interesting option.

Study finds cellular protein as a 'gas pump attendant' of cancer development

The cells which make up our body vary significantly. A liver cell does not look like a muscle cell and each has a unique function. This is because liver cells produce the proteins that characterize them, and muscle cells do the same.

Scientists have more evidence of why clear margins in breast cancer surgery are such good news

When a breast cancer tumor is removed with no signs of cancer left behind, it's great news for patients, and now scientists have more evidence of why.

Researchers discover natural gene therapy for intractable skin disease

Pathogenic gene mutations causing a type of intractable skin disease can be eliminated from some parts of patients' skin as they age, according to Hokkaido University researchers and their collaborators in Japan. This represents a form of natural gene therapy.

Study provides better understanding of how cilia work and what causes oscillations

Human bodies have some built-in systems to care for themselves. The cells that line our lungs, nose, brain and reproductive system have cilia, which are tiny, hair-like structures designed to sweep out fluids, cells and microbes to stay healthy.

Seemingly identical bacteria may have a different effect

Our gut microbiome - the complement of bacteria we carry around in our intestines - has been linked to everything from obesity and diabetes to heart disease and even neurological disorders and cancer.

Pediatric Cell Atlas needed for better understanding of children’s health and illnesses

Research efforts to comprehensively map adult human cells are in progress. But in a Perspective publishing March 28 in the journal Developmental Cell, researchers argue that there is a need to map children’s cells with the same level of granularity.

Single lineage of stem cells contributes to lifelong hippocampal neurogenesis in mice

Scientists once thought that mammals entered adulthood with all of the neurons they would ever have, but studies from the 60s found that new neurons are generated in certain parts of the adult brain and pioneering studies from the 90s helped identify their origins and function.

Researchers discover how mosquitoes smell acidic volatiles in human sweat

Female mosquitoes are known to rely on an array of sensory information to find people to bite, picking up on carbon dioxide, body odor, heat, moisture, and visual cues.

Lab-grown blood vessels provide hope for dialysis patients

Research published this week describes how lab-grown blood vessels were transformed into living tissue when grafted into dialysis patients needing replacement blood vessels.

UTM researchers uncover 'master pacemaker' for biological clocks

What makes a biological clock tick? According to a new study from U of T Mississauga, the surprising answer lies with a gene typically associated with stem and cancer cells.

Maternal age affects how well offspring respond to aging interventions, study shows

Advanced maternal age at the time of giving birth is known to decrease how long the offspring will live and their fecundity. However, why this occurs is unknown, and it remains unclear if maternal age also alters how offspring respond to interventions to aging.

U of G study beginning to unravel mystery of hagfish’s zombie hearts

They are the scavengers of the deep and the dead. Hagfish are slimy bottom-dwellers that live off the carcasses of dead sea creatures and thrive in deep waters where oxygen is hard to come by. In fact, their hearts can keep on beating for 36 hours without any oxygen, making hagfish a champion among anoxia-tolerant fish.

Special input pathway may hold the key to coding sensory information in the cerebellum

As we go about our daily lives, we are constantly bombarded by a steady stream of sensory information. Take a typical morning routine for example- roused from sleep by a shrill alarm, the strong aroma of freshly brewed coffee, and the brake lights and traffic horns of rush hour. In the course of a single day, we experience thousands of different cues across all senses.

Scientists untangle the brain's life-support network

The portion of the brain known as the hypothalamus is small but mighty -- it controls fundamental behaviors and physiology that are essential for survival.

Study explores how a hallucinogenic drug impacts the brains of mice

While there is increasing interest in using hallucinogenic drugs to treat conditions like depression and post-traumatic stress disorder, scientists are just beginning to understand what these drugs actually do in the brain—and how they cause hallucinations.
