abstract = {Colorectal cancer (CRC) can be divided into 4 subtypes of
which consensus molecular subtype 4 (CMS4) is associated
with metastasis and poor survival. Previously, we reported
that the KPN mouse model resembles human CMS4. Strikingly,
although tumor formation in this model is slow and limited,
effective metastasis is observed. To understand this
aggressive behavior, we compared two distinct in vitro KPN
models, organoids and tumoroids. The organoid model only
carries the original mutations, while the tumoroids are
derived from in vivo grown tumors that underwent selection
during development. Here, we reveal that tumoroids harbor
endogenous WNT pathway activity, which can be driven by
tankyrase activity and Cdx2 downregulation. Importantly, WNT
pathway activation was heterogeneous in nature, subject to
regulation and allowed for a mixture of WNT-driven and
YAP-driven cells within tumoroids. This unique type of WNT
pathway activation is not crucial for colonic tumor growth,
but results in metastatic spreading. Intriguingly, these
findings reflect a specific subset of aggressive human CMS4
cancers that display low CDX2 expression and lack of
classical WNT pathway mutations, while having a higher
tendency to metastasize. Together, these data propose a
novel mechanism for WNT pathway activation that drives
metastasis formation in aggressive CRC.},
