Konbertasen eginkizuna tumoreen garapenean sarritan ikertu da eta tumore-zeluletan horienadierazpen-mailan gertatutako aldaketak deskribatu dira. Artikulu honetan, konbertasen garrantziaminbizian ikertzen dugun arren, ikertzen dugun zelula ez da minbizi zelula. Konbertasen adierazpenatumorearen mikroingurunean aztertzen dugu gibeleko sinusoideko zelula endotelialetan konbertasenadierazpena ikertuz. Modu honetan, gibel sinusoideko zelula endotelialen konbertasen adierazpeneangertatutako aldaketak aztertu ditugu, SW620rekin (koloneko tumore-zelula metastatikoak) zein CSCSW620rekin(koloneko tumore-zelula ama metastatikoak) kontaktuan jartzerakoan. Hala, mRNAmailan, zelula endotelial hepatikoen konbertasen adierazpenean aldaketak ikusten dira, eta berezikiinteresgarriak dira PCSK9 eta PACE4-n gertatutako aldaketak.
The role of convertases in tumor development has often been investigated and changes in theexpression level of convertases in tumor cells have been described. In this article, although weinvestigate the importance of convertases in cancer, the cell we investigate is not the cancer cell. Westudied the expression of convertases in the tumor microenvironment by investigating their expressionin hepatic sinusoid endothelial cells. Thus, we have analyzed the changes produced in the expression ofconvertases in hepatic sinusoid endothelial cells upon contact with both SW620 (metastatic colon tumorcells) and CSC-SW620 (metastatic colon stem cells). Thus, at the mRNA level, changes in the expressionof hepatic endothelial cell convertases are observed, with changes in PCSK9 and PACE4 being ofparticular interest.
