Journal Article
Sasso, L., Purdie, L., Grabowska, A. M., Jones, A. T., & Alexander, C. (2018). Time and cell-dependent effects of endocytosis inhibitors on the internalization of biomolecule markers and nanomaterials. Journal of Interdisciplinary Nanomedicine, 3(2), doi:10.1002/jin2.39. ISSN 2058-3273

Endocytosis is an essential function of cells, with key roles in the internalisation of nutrients, signal molecules and also drugs. Endocytic processes are therefore widely investigated in the context of drug delivery, and inhibitors of endocytic pat... Read More

Cancer reversion with oocyte extracts is mediated by cell cycle arrest and induction of tumour dormancy (2018)
