BTYNB is an inhibitor of the oncofetal mRNA-binding protein IMP1 (IC50 = 5 μM for IMP1 binding to c-Myc mRNA). BTYNB downregulates β-TrCP1 mRNA and reduces activation of nuclear transcriptional factors-kappa B (NF-κB). BTYNB disrupts this enhancer function by impairing IGF2 mRNA-binding protein 1 (IGF2BP1)-RNA association.

How to use

In Vitro:

In cells, BTYNB downregulates several mRNA transcripts regulated by IMP1. BTYNB destabilizes c-Myc mRNA, resulting in downregulation of c-Myc mRNA and protein. BTYNB downregulates β-TrCP1 mRNA and reduces activation of nuclear transcriptional factors-kappa B (NF-κB). The oncogenic translation regulator, eEF2, emerges as a new IMP1 target mRNA, enabling BTYNB to inhibit tumor cell protein synthesis. BTYNB potently inhibits proliferation of IMP1-containing ovarian cancer and melanoma cells with no effect in IMP1-negative cells. Overexpression of IMP1 reverses BTYNB inhibition of cell proliferation. BTYNB completely blocks anchorage-independent growth of melanoma and ovarian cancer cells in colony formation assays.
