Human colon cancer cell lines (CRCs) RKO, SW480 and SW620 were investigated for
TG2 involvement in tumour advancement and aggression. TG2 expression correlated
with tumour advancement and expression of markers of epithelial-mesenchymal
transition (EMT). The metastatic cell line SW620 showed high TG2 expression
compared to the primary tumour cell lines SW480 and RKO and could form tumour
spheroids under non- adherent conditions. TG2 manipulation in the CRCs by shRNA
or TG2 transduction confirmed the relationship between TG2 and EMT. TGF?1
expression in CRC cells, and its level in the cell medium and extracellular
matrix was increased in primary tumour CRCs overexpressing TG2 and could regulate
TG2 expression and EMT by both canonical (RKO) and non-canonical (RKO and SW480)
signalling. TGF?1 regulation was not observed in the metastatic SW620 cell line,
but TG2 knockdown or inhibition in SW620 reversed EMT. In SW620, TG2 expression
and EMT was associated with increased presence of nuclear ?-catenin which could
be mediated by association of TG2 with the Wnt signalling co-receptor LRP5. TG2
inhibition/knockdown increased interaction between ?-catenin and ubiquitin shown
by co-immunoprecipitation, suggesting that TG2 could be important in ?-catenin
regulation. ?-Catenin and TG2 was also upregulated in SW620 spheroid cells
enriched with cancer stem cell marker CD44 and TG2 inhibition/knockdown reduced
the spheroid forming potential of SW620 cells. Our data suggests that TG2 could
hold both prognostic and therapeutic significance in colon cancer.
