RNA-Seq of A375 cells treated with tetracycline-based crosslinking probes to identify binding sites for the tetracycline analogs Col-3 and doxycycline on the human ribosome

Project description:Following the identification of the 80S ribosome as a putative target of the tetracycline analogs Col3 and doxycycline, we next sought to identify the precise binding sites for these tetracyclines within the ribonucleoprotein complex. 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 ribosomal components. Pulldown and RNA-Seq of the crosslinked RNAs from our experiments were used to identify enrichment of reverse transcription (RT) stops at ribosomal RNA sites caused by local crosslinking of our probes. This RNA-Seq based RT stop enrichment analysis was compared to results using an non-specific aniline control probe and untreated controls.

RNA-seq of human melanoma cell line A375 treated with the tetracycline analogs Col-3 or doxycycline against untreated controls

Project description:Apart from their antibacterial activity, tetracyclines have demonstrated diverse and beneficial “off-target” biological activities in human disease, spurring interest in their development as non-antimicrobial therapeutics in diseases such as cancer. To better define biological pathways modified by the tetracyclines in human cancer, we sought to determine differential gene expression in the A375 cancer cell line treated with the tetracyclines, Col-3 and doxycycline, relative to control (vehicle-treated) cells. A375 cells were treated with either 10 μM Col-3, 10 μM doxycycline, or vehicle (DMSO) for 6 h, and changes to gene expression were assessed by RNA-Seq.

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

Project description: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 ribosomal components. Pulldown and RNA-Seq of the crosslinked RNAs from our experiments were used to identify enrichment of reverse transcription (RT) stops at ribosomal RNA sites caused by local crosslinking of our probes. In these experiments, UV crosslinking was preformed with the COL-3 and doxycycline probe compounds in the presence and absence of free COL-3 and doxycycline (i.e., parent tetracycline molecules lacking the bifunctional diazirine-azide moiety), which were used as competitors to specifically diminish crosslinking to the ribosomal RNA. Crosslinking to ribosomal RNA was determined using RNA-Seq based RT stop enrichment, which was was also compared to inactive tetracycline probes containing a modified bifunctional linker, a non-specific aniline probe, and untreated controls.

Tetracycline-treated Litomosoides sigmodontis vs. untreated control Litomosoides sigmodontis

Project description:The filarial nematodes Brugia malayi, Wuchereria bancrofti and Onchocerca volvulus cause elephantiasis, dermatitis and blindness, resulting in severe morbidity in developing countries. 1.3 billion people are at risk of infection. Targeting the essential Wolbachia endobacteria of filarial nematodes with doxycycline has proven to be an effective therapy, resulting in a block in embryogenesis and worm development, and macrofilaricidal effects. However, doxycycline is contraindicated for a large portion of the at-risk population. To identify new targets for anti-wolbachial therapy, understanding the molecular basis of the Wolbachia-filaria symbiosis is required. We performed cross-species hybridization by using the Brugia malayi microarray to identify differentially expressed genes in the rodent filaria Litomosoides sigmodontis after depletion of Wolbachia which therefore might have a role in symbiosis. Female adult Litomosoides sigmodontis from patent infections were treated with tetracycline to deplete endosymbiotic Wolbachia bacteria. RNA from tetracycline-treated Litomosoides sigmodontis was compared to untreated age-matched control worms. This experiment was performed for three different timepoints: day 6, 15 and 36 of tetracycline treatment. One biological replicate was performed each with two technical replicates (dye-flip replicates).

Expression data in HTETOP cells following tetracycline or dexrazoxane treatment

Project description:HTETOP cells, derived from the human fibrosarcoma cell line HT1080, express human topoisomearse II α (TOP2A) exclusively from a tetracycline (TET)-regulated transgene, we used HTETOP cells to differentiate between TOP2A-dependent and –independent apoptotic effects of doxorubicin and dexrazoxane. We used microarrays to detect global transcriptional changes in HTETOP cells following tetracycline doxycycline or dexrazoxane treatment. Keywords: Drug treatment comparison
