Example sentences for: mdm

How can you use “mdm” in a sentence? Here are some example sentences to help you improve your vocabulary:

Previous studies have shown that phosphorylation of serines 15, 20, 33 and 37 of p53 block the interaction of p53 with mdm2, leading to stabilization and accumulation of p53 protein in the cell [ 10, 11, 13, 14, 15, 18].
The molecular mechanisms leading to breast malignancies are unclear, but many genetic abnormalities and epigenetic factors have been implicated, including changes affecting known tumor suppressor genes ( p53 , BRCA1, BRCA2 , PTEN/MMAC1/TEP1) and proto-oncogenes (neu/ErbB2/HER2 , ErbB1/EGFR , PRAD-1/cyclin D1 , Mdm2 , and c-myc) [reviewed in ref.
Hepatic RNA was extracted and quantified as we reported previously [ 10 ] . RNA was mixed with 32P-labeled c-myc, mdm2, p53, JunB, and β-actin probes, then co-precipitated, purified, and electrophoresed on 5% polyacrylamide gel.
mdm2 binding is dependent on the phosphorylation status of serine 20 of p53 [ 15], although phosphorylation of serines 15, 33 and 37 also play a role.
The protein product of the mdm2 oncogene is over-expressed in a considerable number of tumors [ 27 ] . This protein is a pivotal negative regulator of p53 [ 27 ] ; it interacts with the P53 protein masking its transcriptional domain and accelerating its proteasomal degradation [ 21 27 ] . The later process involves the deacetylation and ubiquitylation of the p53 protein by mdm2 [ 28 ] . Inactivation and/or degradation of p53 diminishes the cell ability to undergo apoptosis [ 21 ] . Conversely, p53 may influence mdm2.
