Control of 3'-end formation in human breast cancer cells

Proper maturation of the 3' terminus of messenger RNAs (mRNAs) is essential to ensure functional gene expression. Most eukaryotes employ alternative polyadenylation (APA) to increase the number of RNA isoforms transcribed from one gene, thus allowing not only production of different proteins but also tissue-specific diversification of the protein function. However, aberrant APA leads to disruption of gene expression with severe consequences on genome stability, and can cause human disease and cancer. I am studying the mechanisms regulated by RNA binding proteins and chromatin modifications that prevent aberrant APA in breast cancer cells, which can help identify possible therapeutic targets for breast cancer treatment/prevention. A preliminary study can be found on biorXiv.

Regulation of transcriptional pausing by RNA binding proteins in breast cancer cells

Transcription across most human genes is generally paused near the start, both to allow quality control of the newly synthesised RNA and to regulate transcription levels. Disruption of this pathway has been linked to human disease and cancer. Several protein factors with a known role in cancer biology have been identified as regulators of transcription pausing (including c-myc). My research is focussing on characterising a possible role for oncogenic RNA binding proteins in this process, and understand their contribution to cancer progression and metastasis.

PREVIOUS RESEARCH INTERESTS

Chromatin regulation of transcription in the budding yeast Saccharomyces cerevisiae

During my PhD under the supervision of Dr Manolis Papamichos-Chronakis I described a mechanism of RNA quality control through premature transcription termination that depends on the chromatin remodeller INO80. A preprint of this study is currently deposited on biorXiv.

Integrity of human telomeres upon exposure to X-radiation

During my BSc and Master's I analysed the effects of X-radiation on human telomere length and integrity, cellular senescence and apoptosis. Furthermore, I found that the coenzyme Q10 has a role in protecting human telomeres from radiation-induced DNA damage. Part of my findings were published in Microgravity Science and Technology
