Researchers tested thousands of existing drugs to find new ways to kill multiple myeloma cancer cells, and discovered that a drug called RTA408 works by blocking a cellular cleanup system that myeloma cells depend on to survive. When RTA408 shuts down this cleanup system, cancer cells die through a specific mechanism involving the cell's outer membrane, and it kills even myeloma cells that have become resistant to current treatments. This finding could lead to a new treatment option for multiple myeloma patients who no longer respond to standard drugs.

Plain English
This study looked at how effective a type of chemotherapy, given directly to the liver, is for patients with liver cancer that has spread after they had surgery for esophageal cancer. Out of 19 patients, those who received this treatment early or as ongoing care after responding to another chemotherapy had a higher chance of survival, with a one-year survival rate of 67% compared to just 20% for those who received it later. Overall, patients had a median survival of about 10.8 months, and while this treatment had some side effects for a few people, it showed promise, especially for those who responded to earlier treatments. Who this helps: This research benefits patients with liver metastasis after esophageal cancer treatment.

Plain English
This research looked at how a protein called PERK affects blood stem cells (HSCs) when they are under stress. The study found that while PERK isn't needed for normal blood cell production, it plays a key role during stress by causing HSCs to multiply too much and eventually lose their ability to renew themselves. Specifically, when certain stress-related processes were disrupted, removing PERK improved the overall health of these stem cells by preventing this overgrowth. Who this helps: This helps patients who rely on healthy blood stem cells, such as those undergoing chemotherapy.

Plain English
Researchers tested thousands of existing drugs to find one that could block a cellular cleanup system called ERAD, and discovered that a drug called omaveloxolone (RTA408) does this effectively. When they applied this drug to multiple myeloma cancer cells—including ones that resist other treatments—it triggered the cancer cells to self-destruct by activating their internal death signals. This matters because multiple myeloma is currently incurable, and omaveloxolone could become a new treatment option, either alone or combined with existing drugs.

Plain English
This study focused on a 67-year-old woman with a serious type of esophageal cancer that couldn't be surgically removed.
