abstract = {Patients with advanced colorectal cancer often are treated
with systemic cytotoxic therapy using fluouracil (5-FU),
oxaliplatin, irinotecan, and FOLFOX or FOLFIRI combination
protocols. Additionally, signaling pathways that are active
in colorectal cancer can be therapeutically targeted. Here,
we examined if chemotherapy impacts on WNT, MAPK and NOTCH
signaling pathways in xenograft models of colon cancer.
Furthermore, we tested if combining chemotherapy with MAPK
and NOTCH inhibition has superior therapeutic effects. We
demonstrate that tumor cells with high WNT, MAPK and NOTCH
activity are variably affected by different chemotherapeutic
regimens, while vital tumor cells with different pathway
activity remain in treated colon cancer xenografts. Although
this provided a rationale to additionally target pathway
activity, we found no significant increase in therapy
response when combining MAPK and NOTCH inhibition with
fluouracil chemotherapy. We attribute this finding to a
decrease in tumor cell proliferation upon MAPK and NOTCH
inhibition, resulting in reduced effectiveness of cytotoxic
treatment. Therapeutic benefits of combining chemotherapy
with targeting of signaling pathways that are active in
colon cancer thus must be critically evaluated for patients
with colorectal cancer. This article is protected by
