Summary The lab is interested in identifying novel transcription factors that regulate this process, and investigate whether these factors are involved in regeneration.
The bidirectional conversion between differentiated cells and stem cells often underlies carcinogenesis. Mechanisms must be in place to prevent differentiated cells from reverting to multipotent stem cells. We have recently discovered that zinc finger transcription factor Nerfin-1 is required to maintain neurons in a differentiated state (Froldi et al., 2015). In the absence of Nerfin-1, neurons rapidly increase their cellular growth and switch on stem cell markers, then form tumours.
