Estrogenic and anti-estrogenic effects of PFASs could depend on the presence of estrogen

Perfluoroalkyl substances (PFASs) have received intense scrutiny in recent years because of their persistence in the environment and potential endocrine-disrupting effects. However, their estrogenic activities are controversial, with different studies showing apparently contradictory results. Now, researchers reporting in ACS’ Environmental Science & Technology have used a combination of laboratory experiments and computer […]

OneSkin Launches a Topical Senolytic Treatment

Senescent cells are damaging to tissue function and health when they linger and grow in number, as becomes the case with age. They contribute to the chronic inflammation of aging via their signaling, the senescence-associated secretory phenotype. In skin, senescent cells are most likely responsible for a sizable fraction of […]

What do breast cancer cells feel inside the tumour?

Using a new technique, a team of McGill University researchers has found tiny and previously undetectable ‘hot spots’ of extremely high stiffness inside aggressive and invasive breast cancer tumours. Their findings suggest, for the first time, that only very tiny regions of a tumour need to stiffen for metastasis to […]

Scientists use clues in the human genome to discover new inflammatory syndrome

Researchers from the National Institutes of Health (NIH) have discovered a new inflammatory disorder called vacuoles, E1 enzyme, X-linked, autoinflammatory and somatic syndrome (VEXAS), which is caused by mutations in the UBA1 gene. VEXAS causes symptoms that included blood clots in veins, recurrent fevers, pulmonary abnormalities and vacuoles (unusual cavity-like structures) in […]

Silencing gene expression to cure complex diseases

Many people think of new medicines as bullets, and in the pharmaceutical industry, frequently used terms like “targets” and “hits” reinforce that idea. Immuneering co-founder and CEO Ben Zeskind ’03, PhD ’06 prefers a different analogy. His company, which specializes in bioinformatics and computational biology, sees many effective drugs more […]

‘Genome Archeologists’ at U of T and UHN activate immune response against cancer

Researchers at University Health Network and the University of Toronto have identified silent and ancient DNA elements buried in our genomes that, when reactivated, can initiate a powerful immune response to kill colorectal cancer cells. The researchers also discovered a key enzyme that human cancer cells use to prevent that […]

Study shows how exercise stalls cancer growth through the immune system

People with cancer who exercise generally have a better prognosis than inactive patients. Now, researchers at Karolinska Institutet in Sweden have found a likely explanation of why exercise helps slow down cancer growth in mice: Physical activity changes the metabolism of the immune system’s cytotoxic T cells and thereby improves […]

How Stem Cells Choose their Careers

“What do you want to be when you grow up?” is a question it seems like every child gets asked. A few precocious ones might answer “a doctor” or “an astronaut,” but most will probably smile and shrug their shoulders. But well before a child could comprehend the question or […]

New insights into autoimmune disease

The immune response is a balancing act: Too much can lead to inflammatory or autoimmune disease; too little could lead to a serious infection. Regulatory T cells, or Tregs, are important players in striking this balance, acting as “brakes” on the immune response so it doesn’t go overboard. Consequently, controlling […]

Cancer's Dangerous Renovations to our Chromosomes Revealed

Cancer remodels the architecture of our chromosomes so the disease can take hold and spread, University of Virginia researchers have revealed. This remodelling is important because the arrangement of the components in our chromosomes actually affects the workings of our genes. With these renovations, cancer begins making a comfortable home […]
