Metarrestin, a perinucleolar compartment inhibitor, effectively suppresses metastasis

Abstract: Metastasis remains a leading cause of cancer mortality due to the lack of specific inhibitors against this complex process. To identify compounds selectively targeting the metastatic state, we used the perinuclear compartment (PNC), a complex nuclear structure associated with metastatic behaviors of cancer cells, as a phenotypic marker for a high-content screen of over 140,000 structurally diverse compounds. Metarrestin, obtained through optimization of a screening hit, disassembles PNCs in multiple cancer cel… Show more

“…The prevalence of PNC bodies (expressed as the fraction of cells containing one or more PNCs) was 38.2% in untreated murine KPC tumors (Fig. 4a) which was similar to the PNC prevalence in the previously examined NOD/IL2 gamma (null) PANC1 metastasis model (35.1%) and higher than in cancer cell lines derived from primary pancreatic tumors (average ~ 23.5%) [15]. After 14-day treatment with 25 mg/kg metarrestin by oral gavage, PNC prevalence in KPC tumors was reduced to 9.8% (Fig.…”

“…Suppression of Pol I activity partially recapitulates the effect of Metarrestin, although the drug does not induce genotoxic stress in cells. Remarkably, Metarrestin proved to be very effective in vivo, as it substantially blocked formation of metastasis in both xenograft and PDX tumor models, without displaying adverse effects in healthy animals [14].…”

“…One of the recent additions to the RNA polymerase inhibitors is metarrestin which functions by impairing Pol I-ribosomal DNA interaction and inhibiting the function of Pol I (Frankowski et al, 2018). It also inhibits the transcription of Pol I and disrupts the function of the perinuclear compartment which is a complex nuclear structure associated with metastatic cancer.…”
