abstract = {Aberrant Wnt pathway activation is a key driver of
colorectal cancer (CRC) and is essential to sustain tumour
growth and progression. Although the downstream
protein-coding target genes of the Wnt cascade are well
known, the long non-coding transcriptome has not yet been
fully resolved.In this study, we aim to comprehensively
reveal the Wnt-regulated long non-coding transcriptome and
exploit essential molecules as novel therapeutic targets.We
used global run-on sequencing to define β-catenin-regulated
long non-coding RNAs (lncRNAs) in CRC. CRISPRi dropout
screens were subsequently used to establish the functional
relevance of a subset of these lncRNAs for long-term
expansion of CRC.We uncovered that LINC02418 is essential
for cancer cell clonogenic outgrowth. Mechanistically,
LINC02418 regulates MYC expression levels to promote CRC
stem cell functionality and prevent terminal
differentiation. Furthermore, we developed effective small
interfering RNA (siRNA)-based therapeutics to target
LINC02418 RNA in vivo.We propose that cancer-specific
Wnt-regulated lncRNAs provide novel therapeutic
opportunities to interfere with the Wnt pathway, which has
so far defied effective pharmacological inhibition.},
