Job description

Supervisor: Dr Magdalena CrossleyDepartment/location: Cancer Research UK Cambridge Institute (CRUK CI)Course start date: 1st October 2025OverviewDr Magdalena Crossley wishes to recruit a PhD student to work on the project entitled: ‘Investigating the causes and consequences of R-loop dysregulation in cancer’.For further information about CRUK CI’s newest research group, please visit our website at:Project detailsRNA-DNA hybrid structures, including R-loops, form on the genome and have physiological roles in regulating gene expression. However, dysregulation of R-loops can threaten genome maintenance and has been linked to cancer, neurodegeneration and autoimmunity. We investigate, at the molecular level, how R-loops and RNA-DNA hybrids become pathological, impacting genome stability and innate immunity.We recently discovered that dysregulation of R-loop metabolism by cancer-associated mutations leads to the excision of R-loops. Excised RNA-DNA hybrids are exported from the nucleus and build up in the cytoplasm of cells, activating an innate immune response (Crossley et al., Nature 2023). We developed new biochemical, genomics and imaging approaches to study RNA-DNA hybrids across different cellular compartments. PhD projects are expected to gain mechanistic and translational insights into this novel and fascinating population of nucleic acids. Projects will be tailored to the successful individual(s) based on interests and previous experience, incorporating one or more of the following areas:

• Genome biology and cellular dynamics of RNA-DNA hybrids, eg their biogenesis from oncogene activation, retroelements and mitochondria.
• RNA-DNA hybrids in innate immunity and cellular responses, eg senescence.
• Extracellular RNA-DNA hybrid release.
• Developing genomics and computational approaches for interrogation of RNA-DNA hybrids in cells and patient samples.

Your project will explore the role of RNA-DNA hybrids in human cells, with the aim to translate our mechanistic findings into patient samples and inform new therapeutic entry points.You can expect to develop innovative skills in both experimental and computational approaches, benefit from close mentoring, and have an opportunity to shape the scientific direction of a new research group.Further reading * Crossley M.
