Biochimie. 2018 Jun 02;: Authors: Zinovieva OL, Grineva EN, Prokofjeva MM, Karpov DS, Zheltukhin AO, Krasnov GS, Snezhkina AV, Kudryavtseva AV, Chumakov PM, Mashkova TD, Prassolov VS, Lisitsyn NA Abstract Early prediction of tumor relapse depends on the identification of new prognostic cancer biomarkers, which are suitable for monitoring tumor response to different chemotherapeutic drugs. Using RNA-Seq, RT-qPCR, bioinformatics, and studies utilizing the murine tumor xenograft model, we have found significant and consistent changes in the abundance of five lincRNAs (LINC00973, LINC00941, CASC19, CCAT1, and BCAR4) upon treatment of both HT-29 and HCT-116 cells with 5-fluorouracil, oxaliplatin, and irinotecan at different doses and durations; both in vitro and in vivo. The most frequent changes were detected for LINC00973, whose content is most strongly and consistently increased upon treatment of both colon cancer cell lines with all three chemotherapeutic drugs. Additional studies are required in order to determine the molecular mechanisms by which anticancer drugs affect LINC00973 expression and to define the consequences of its upregulation on drug resistance of cancer cells.
