SIRT1 Undergoes Alternative Splicing in a Novel Auto-Regulatory Loop with p53 [PDF]
Background The NAD-dependent deacetylase SIRT1 is a nutrient-sensitive coordinator of stress-tolerance, multiple homeostatic processes and healthspan, while p53 is a stress-responsive transcription factor and our paramount tumour suppressor. Thus, SIRT1-

Subendothelial macrophages are a major cellular component of atherosclerotic lesions. In response to subendothelial retention of modified lipoproteins,1 2 blood-borne monocytes enter the subendothelial space, differentiate into macrophages, and accumulate large amounts of lipoprotein-derived cholesterol (foam cells).3 4 Specific consequences of ...

The degradation of p53 and its major E3 ligase Mdm2 is differentially dependent on the proteasomal ubiquitin receptor S5a. [PDF]
p53 and its major E3 ligase Mdm2 are both ubiquitinated and targeted to the proteasome for degradation. Despite the importance of this in regulating the p53 pathway, little is known about the mechanisms of proteasomal recognition of ubiquitinated p53 and

Macroautophagy (autophagy hereafter) captures, degrades, and recycles intracellular components to maintain metabolic homeostasis and protein and organelle quality control. Autophagy thereby promotes survival in starvation and prevents tissue degeneration. There is an important relationship between autophagy and p53.

p53 α-Helix mimetics antagonize p53/MDM2 interaction and activate p53 [PDF]
Abstract Overexpression or hyperactivation of MDM2 contributes to functional inactivation of wild-type p53 in nearly 50% of tumors. Inhibition of p53 by MDM2 depends on binding between an NH2-terminal (residues 16–28) p53 α-helical peptide and a hydrophobic pocket on MDM2, presenting an attractive target for development of inhibitors ...

Inactivation and inducible oncogenic mutation of p53 in gene targeted pigs. [PDF]
Mutation of the tumor suppressor p53 plays a major role in human carcinogenesis. Here we describe gene-targeted porcine mesenchymal stem cells (MSCs) and live pigs carrying a latent TP53(R167H) mutant allele, orthologous to oncogenic human mutant TP53 ...

A long-term goal in the cancer-field has been to develop strategies for treating p53-mutated tumors. A novel small-molecule, PG3-Oc, restores p53 pathway-signaling in tumor cells with mutant-p53, independently of p53/p73. PG3-Oc partially upregulates the

Tumor suppressor protein p53 (TP53) is a key transcription factor that, in response to various stress signals, regulates numerous genes involved in a broad range of cellular functions including DNA repair, apoptosis, cell cycle arrest, senescence, metabolism, etc [...]

Independent regulation of P53 stabilisation and activation after Rb deletion in primary epithelial cells [PDF]
We have previously reported that deletion of the retinoblastoma gene Rb leads to rapid but transient p53 stabilisation. We investigated here the pathways involved.
