Description

General description

A cell-permeable thioethanone compound that upregulates p53 family-responsive element-dependent reporter plasmid transcription activity in cells bearing Glu266, His273, Lys280, or Trp278 mutant p53 by increasing the cellular protein, but not mRNA, level of the p53 homologue p73 (by ~3.7-fold in A431 cells in 20 h with 2 µg/ml RETRA) as well as by disrupting p73 interaction with mutant p53, while exhibiting no similar effects in wild-type p53-bearing or p53-null cells. RETRA is shown to increase transcription of proapoptotic genes (5- and >10-fold increase, respectively, of PUMA/BBC3 and p21/CDKN1A, with 1.5 µg/ml RETRA for 14 h), induce apoptosis, and inhibit the growth of A431, but not wild-type p53-bearing or p53-null cells, in a p53- and p73-dependent manner in vitro, as well as delay (by ~4 days) and reduce (by ~50% on day 25) A431-derived tumor formation in mice (0.4 mg/animal via 6 daily i.p.) in vivo.
