Therefore, when facing a high-grade and pleomorphic sarcoma biopsy from the retroperitoneum, judicious use of immunohistochemical stains for MDM2 and CDK4 is helpful in identifying dedifferentiated liposarcoma.

In addition to approved medicines MabThera/Rituxan and Gazyva/Gazyvaro, Roche's pipeline of investigational hematology medicines includes an anti-CD79b antibody drug conjugate (RG7596/polatuzumab vedotin), a small molecule antagonist of MDM2 (RG7112) and in collaboration with AbbVie, a small molecule BCL-2 inhibitor (venetoclax/RG7601/GDC-0199/ABT-199).
In this study, a potential of mean force method was used to calculate the absolute binding affinities for the disordered p53 and MDM2 when the proline in p53 is in both cis and trans conformations.
Studies have shown that a Single Nucleotide Polymorphism (SNP) on promoter region of MDM2 gene, the SNP309 (T to G change on nucleotide 309 of the first intron), results in a higher level of MDM2 mRNA and MDM2 protein, and consequent reduction of the p53 pathway.
Krishna et al studied protein over expression (MDM2) in ameloblastoma and oral squamous cell carcinoma (OSCC) and found that the keratinizing cells of acanthomatous ameloblastoma showed less MDM2 reactivity as compared to high reactivity in OSCC which could be suggestive of terminal differentiation and non-proliferative phenotype of central cells.
To clarify this hypothesis, it is mentioned that Mdm2 (Mouse double minute 2 homolog) which has been recognized as E3 ubiquitin-protein ligase, regulates both the transcriptional activity and the half-life of p53 in a negative feedback loop.
2007), 3 case-control studies on the 309T> G polymorphism of MDM2 (Mouse double minute 2 homolog) gene (Sousa, Pando, Breda, Catarino, & Medeiros, 2011; Xiao et al.
