As research involving the transplantation of human “mini-brains”—known as brain organoids—into animals to study disease continues to expand, so do the ethical debates around the practice. A new paper published in Cell Stem Cell by researchers from Penn Medicine and the Department of Veterans Affairs sought to clarify the abilities of brain organoids and suggests an ethical framework that better defines and contextualizes these organoids and establishes thresholds for their use.

A research team from the Johns Hopkins Kimmel Cancer Center reports it has discovered a metabolic vulnerability in multiple types of cancer cells that bear a common genetic mutation affecting cellular machines called spliceosomes. In test tube and mouse experiments, the researchers learned that the resulting spliceosome malfunction cripples the cells’ chemical process for generating the amino acid serine, making the cancer cells dependent on external (dietary) sources of the amino acid. When mice were fed a serine-restricted diet, their tumors (myeloid sarcomas, the solid tumor version of acute myeloid leukemia) shrank, suggesting that a similar dietary intervention might be helpful for patients bearing the mutation, the researchers say. Among foods high in serine are soybeans, nuts, eggs, lentils, meat and shellfish.

Newly discovered chemical-sensing cells in the gums protect the mouth by standing guard against infections that damage soft tissue and destroy the bone that supports the teeth. With the help of bitter taste receptors that also detect byproducts from harmful bacteria, these special gum cells trigger the immune system to control the amount and type of bacteria in the mouth and could one day lead to personalized dental treatments against gum disease.
