Polyamines promote cellular proliferation, and their levels are controlled by ornithine decarboxylase antizyme 1 (Az1), through the proteasome-mediated, ubiquitin-independent degradation of ornithine decarboxylase (ODC), the rate-limiting enzyme of polyamine biosynthesis. Az1-mediated degradation of...

Neuroblastoma and medulloblastoma are the most common solid tumors in children, with MYC(N) proto-oncogene amplification serving as a key marker of aggressive disease and poor treatment outcomes. However, the complex nature of the challenging MYC(N) protein underscores the urgent need for additional...

In chimera assays, murine naïve embryonic stem (ES) cells usually produce better chimeras than the more primed epiblast-derived stem (EpiS) cells. Overexpression of the cytoskeleton-associated protein LIMA1/EPLIN in EpiS cells improves the rate of successful chimeras, while the knockout of LIMA1 in ...
