Northwestern Medicine investigators have identified a previously unknown regulator of tumor immune evasion, which may help improve the efficacy of current and future antitumor immunotherapies, according to recent findings published in the Journal of Clinical Investigation.

“The study provides a molecular insight into understanding why some cancer patients cannot be treated by the checkpoint blockade antitumor therapy, but others can,” said Deyu Fang, Ph.D...

Often referred to as the “powerhouses of the cell,” mitochondria are well known for their role as energy suppliers, but these organelles are also critical for maintaining our overall health. Mitochondrial stress is associated with aging and age-related diseases, including neurodegeneration, but there has been a limited understanding of the cellular mechanisms behind this mitochondrial stress signaling...

Researchers at the University of California, San Francisco, have successfully leveraged an FDA-approved drug to halt growth of tumors driven by mutations in the RAS gene, which are famously difficult to treat and account for about 1 in 4 cancer deaths.

Taking advantage of what they discovered to be the cancer cells’ appetite for a reactive form of iron, the researchers tweaked an anticancer drug to operate only in these iron-rich cells, leaving other cells to function normally...
