Nonetheless, the regulatory interactions between c-Myc and p53 are not retained by cancer cells as is evident from the often-imbalanced expression of c-Myc over wildtype p53. Although p53 repression in cancer cells is frequently associated with the loss of ARF, we disclose here an alternate mechanism whereby c-Myc inactivates p53 through the actions of the c-Myc-Inducible Long noncoding RNA Inactivating P53 (MILIP). MILIP functions to promote p53 polyubiquitination and turnover by reducing p53 SUMOylation through suppressing tripartite-motif family-like 2 (TRIML2). MILIP upregulation is observed amongst diverse cancer types and is shown to support cell survival, division and tumourigenicity. Thus our results uncover an inhibitory axis targeting p53 through a pan-cancer expressed RNA accomplice that links c-Myc to suppression of p53.]]> Wed 17 Nov 2021 16:28:34 AEDT ]]> The N-Myc-responsive lncRNA MILIP promotes DNA double-strand break repair through non-homologous end joining https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:51136 Tue 22 Aug 2023 15:58:29 AEST ]]> The pan-cancer lncRNA PLANE regulates an alternative splicing program to promote cancer pathogenesis https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:45314 Thu 27 Oct 2022 13:56:29 AEDT ]]> SENEBLOC, a long non-coding RNA suppresses senescence via p53-dependent and independent mechanisms https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:40525 Mon 08 Aug 2022 15:05:19 AEST ]]>
