Demonstrated that the nuclear matrix protein CIZ1 facilitates the localization of Xist RNA to the inactive X-chromosome territory, contributing to understanding X-chromosome inactivation.
Showed that CIZ1 is required for the maintenance of the epigenetic landscape and that this maintenance is corrupted in differentiated fibroblasts in long-term culture.
Identified that CIZ1-F, an alternatively spliced variant of CIZ1, is overrepresented in early-stage common solid tumors, suggesting its potential role in cancer development.
Discovered that dominant CIZ1 fragments drive epigenetic instability and are expressed in early-stage cancers, highlighting their potential as therapeutic targets.
Revealed that epigenetic deprogramming occurs through the disruption of CIZ1-RNA nuclear assemblies in early-stage breast cancers, providing insights into epigenetic mechanisms in cancer.
Demonstrated that the nuclear matrix protein CIZ1 is localized to the inactive X chromosome, and its absence leads to loss of Xist localization and female-specific lymphoproliferative disorder in mice.
Emma Stewart investigates the role of CIZ1 in epigenetic maintenance and its disruption in early-stage cancers, with a focus on RNA nuclear assemblies and epigenetic instability. Her research contributes to understanding cancer development and potential therapeutic targets.
