EMT represents the dominant program within advanced stages of colon cancer, where
cells acquire migratory characteristics in order to invade secondary tissues and
form metastasis. Where the majority of the therapeutic strategies are
concentrated on the reduction of the tumor mass through different apoptotic
mechanisms, the present study advocates an important role for miR-205-5p in
impairment of colon cancer cells migration and restoration of the epithelial
phenotype. Upon identification of a homogenous downregulated profile for
miR-205-5p in colon adenocarcinoma patients, functional studies demonstrated that
experimental upregulation of this sequence is able to significantly raise the
levels of E-cadherin through direct inhibition of ZEB1. Moreover, the elevation
in CDH1 expression was translated into functional parameters where cells lost
their invasion and migratory characteristics and formed homogenous clusters
through adhesion interactions. Survival analysis of colon adenocarcinoma patients
revealed that low levels of miR-205-5p are associated with an unfavorable
prognostic compared to those with increased expression, demonstrating the
possible clinical utility of miR-205-5p replacement. Exogenous administration of
miRNA mimics was not associated with significant changes in cell viability or
inflammatory pathways. Therefore, the proposed strategy is aiming towards
inhibition of metastasis and limitation of the tumor borders in advanced stages
patients in order to prolong the survival time and to increase the efficiency of
the current therapeutic strategies.
