New research finds novel drug target for acute myeloid leukemia, bringing hope for cancer patients

Researchers at UT Health San Antonio have identified a novel drug target for acute myeloid leukemia, which showed significant delays in disease progression and improved survival rates. The protein paraspeckle component 1 (PSPC1) plays a crucial role in the disease, and targeting it may offer new treatment options for AML patients.

Driving the CAR to fight acute myeloid leukemia

Researchers at Osaka University identify a specific molecule, HLA-DRB1, that can be targeted by CAR-based therapy for AML. Engineered CAR T cells showed strong and specific anti-AML effects in vitro and in vivo with mice, without overt toxicity.

North America is dripping from below, geoscientists discover

Researchers have discovered that the underside of the North American continent is experiencing 'cratonic thinning', a phenomenon where the continent is slowly losing its stability and rock layers. This process, driven by the subduction of the Farallon Plate, may eventually stop as the plate sinks deeper into the mantle.
