Certain metabolites linked to stem cell function in the intestine: Molecules called ketone bodies may improve stem cells’ ability to regenerate new intestinal tissue

MIT biologists have discovered an unexpected effect of a ketogenic, or fat-rich, diet: They showed that high levels of ketone bodies, molecules produced by the breakdown of fat, help the intestine to maintain a large pool of adult stem cells, which are crucial for keeping the intestinal lining healthy. The…

AI reveals new breast cancer types that respond differently to treatment: Revelations could personalize treatment, including picking out those likely to benefit from immunotherapy

Scientists have used artificial intelligence to recognise patterns in breast cancer — and uncovered five new types of the disease each matched to different personalised treatments. Their study applied AI and machine learning to gene sequences and molecular data from breast tumours, to reveal crucial differences among cancers that had…

Bone cells suppress cancer metastases

In breast cancer, there are cases of women and men whose cancer returns in their bones 20-30 years after they were treated for their primary disease and thought they were cancer-free. This phenomenon always puzzled Jefferson researcher Karen Bussard, PhD. How is it possible that breast cancer cells from a…

On the origin of B1 cells

A new MDC study may resolve a decades-old debate in immunology: A team led by Prof. Klaus Rajewsky reports in Science that distinct progenitor cells are not required for the development of B1 cells. Instead, the team’s experiments show that B1-typical B-cell receptor can reprogram B2 cells into B1 cells,…
