New ways to deliver high doses of cancer killing drugs

Cancer treatment

Researchers investigating ways to deliver high doses of cancer-killing drugs inside tumors have shown they can use a laser and light-activated gold nanoparticles to remotely trigger the release of approved cancer drugs inside cancer cells in laboratory cultures. The study by researchers at Rice University and Northwestern University Feinberg School of …

Life-threatening reactions after taking drug for treating cancer

Cancer treatment

Albert Einstein College of Medicine researchers report that the composition of people’s gut bacteria may explain why some of them suffer life-threatening reactions after taking a key drug for treating metastatic colorectal cancer. The findings, described online in npj Biofilms and Microbiomes, a Nature research journal, could help predict which …

Membrane vesicles have potential applications in nanotechnology

Bacillus subtilis

Many bacteria release membrane vesicles, which are nanoscale spheres consisting of a cellular membrane containing various biomolecules. Membrane vesicles can transport DNA and proteins, and are involved in bacterial interactions. They have potential applications in nanotechnology and biomedicine; e.g., in cancer treatment. However, the formation of membrane vesicles by bacteria …

Magic mushrooms produce psychoactive compounds

Magic mashroom

Little fungi pack a punch: “Magic mushrooms” of the Psilocybe species produce psychoactive compounds that alter perception when ingested. Recently, the effects on the neuronal system caused by their ingredient psilocybin have attracted the interest of pharmacologists. German scientists have now identified four of the enzymes responsible for the biosynthesis of psilocybin. …

killer peptide that can eliminate therapy resistant cells

Killer peptide

A new study by University of Kentucky Markey Cancer Center researchers shows that when therapy-sensitive cancer cells die, they release a killer peptide that can eliminate therapy resistant cells. Tumor relapse is a common problem following cancer treatment, because primary tumor cells often contain therapy-resistance cancer cells that continue to …
