2. Apoptosis
  3. MDM-2/p53 Apoptosis
  4. DPBQ

DPBQ activates p53 and triggers apoptosis in a polyploid-specific manner, but does not inhibit topoisomerase or bind DNA. DPBQ elicits expression and phosphorylation of p53 and this effect is specific to tetraploid cells.

Description

DPBQ activates p53 and triggers apoptosis in a polyploid-specific manner, but does not inhibit topoisomerase or bind DNA. DPBQ elicits expression and phosphorylation of p53 and this effect is specific to tetraploid cells[1].

IC50 & Target

p53[1]
In Vitro

DPBQ elicits apoptosis and cell death and is selective for effects in 4N cells. DPBQ elicits expression and phosphorylation of p53 and this effect is specific to tetraploid cells. Knockdown of TP53 restores proliferation of tetraploid cells in the presence of DPBQ[1].

Kinase Assay
[1]

For Western blot analysis, 2N and 4N RPE1 cells are treated with DMSO, 50 ng/mL doxorubicin, or 1 μM DPBQ for 48 hours. Western blotting is performed with a SDS-PAGE Electrophoresis and semidry transfer. Samples are analyzed by chemiluminescence. β-actin is used as a protein loading control[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
Cell Assay
[1]

For Apoptosis assays, 2N and 4N RPE1 cells are treated with DMSO, 60 nM staurosporine, or 1 μM DPBQ for 48 hours. Apoptosis is evaluated by an Annexin V-PE/7-AAD apoptosis detection kit. For the flow cytometry analysis, the percent positive cells in the upper right and lower right quadrants are summed to give the total number of apoptotic cells. Three independent replicates are performed[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
