USP20 mediates malignant phenotypic changes in bladder cancer through direct interactions with YAP1.

Yes-associated protein 1 (YAP1) has attracted attention for its potential in the treatment of various types of malignancies. The Hippo-YAP1 axis is inhibited in bladder cancer (BC), which is a major driver of BC progression and oncogenesis. Hippo pathway activity is controlled by the phosphorylation cascade in the MST1/2-LATS1/2-YAP1 axis, in addition to other modifications such as ubiquitination of the Hippo pathway proteins through the co-regulation of E3 ligases and deubiquitinases.

Tractable Method for Rapid Quality Assessment of Therapeutic Antibodies in Harvested Cell Culture Fluid based on FcγRIIIa-Immobilized Magnetic Microspheres.
