I'm a Master’s student in Molecular Biochemistry. My supervisor has validated two research themes, and now I need to narrow them down to a single, feasible project for my final year. I’m torn between autoimmune mechanisms and oncology.

1. AITD: Epigenetic regulators (DNA methylation/ncRNA) in Hashimoto’s/Graves’ or the role of ER Stress (Unfolded Protein Response) in thyroid autoimmunity.

2. Thyroid Cancer: Identifying molecular biomarkers in the MAPK pathway (e.g., CCNA1 or SFN) to differentiate benign vs. malignant nodules using genomic classifiers.

I’m envisaging a future PhD application next year, and I’d like then for my Thetis to be about molecular crosstalk between AITDs and the tumor microenvironment in other glandular cancers like breast cancer. So is it better to focus on the Microbiome/AITD axis or the clinical utility of Cancer Biomarkers?
