Subject: In our study, we outlined a prominent expression profile for CXC chemokines GROalpha and ENA-78 with respect to CRC pathology. ENA-78 exhibited a very pronounced significant overexpression in the CRC and CRLM tissues with respect to CRA tissues thus indicating a vast progressive increase in the transition from the premalignant condition to the development of the malignant status. Along with a much more pronounced up-regulation in the malignant tissues in comparison to GROalpha and a significant clinicopathological correlation with early stage onset of CRC, we regard ENA-78 as a most interesting candidate with respect to a potential role in the progression from CRA to CRC and thus, in the initiation of CRC. The content of the manuscript is original and it has not been published or accepted for publication, either in whole or in part, in any form. No part of the manuscript is currently under consideration for publication elsewhere.
