WebJan 6, 2024 · Whether, whether RB1 inactivation is a feature of the tumour at diagnosis prior to treatment or whether it is acquired at the point of drug resistance, may give further insight into its potential role in either predicting or facilitating histological transformation. Consistent with previous efforts, Pros et al. 4. WebWe showed that MYCN overexpression leads to RB inactivation by inducing RB hyperphosphorylation during the G1 phase through cell cycle synchronization experiments. Moreover, we generated two MYCN-amplified NB cell lines conditionally knockdown (cKD) for the RB1 gene through a CRISPRi approach.
