RNA-Seq of A375 cells treated with tetracycline-based crosslinking probes, with and without competition by parent tetracyclines, to show specific binding of the tetracycline analogs Col-3 and doxycycline on rRNA substructures of the human ribosome

ABSTRACT: Upon finding that the tetracyclines COL-3 and doxycycline target unique rRNA substructures of the 80S ribosome (E-MTAB-7147), we confirmed these putative ribosomal binding sites by showing that tetracycline-based crosslinking probes are specifically competed from these rRNA structures by their parent drugs. In short, we incorporated dual bioorthogonal handles into tetracycline-based probes, containing both a photoactive diazirine to enable direct probe crosslinking to the human ribosome and an azide handle to allow selective enrichment of crosslinked biomolecules via copper-free ‘click’ chemistry. The COL-3 and doxycycline probes were each incubated with A375 cells, followed by irradiation at 365 nm to induce photolysis of the diazirine moiety and subsequent crosslinking to adjacent riboso
