Abstract :Aim: The low-density lipoprotein receptor gene insert ignore into journalissuearticles values(LDLR); family plays a fundamental role in many malignancies and may have a putative cancer-boosting function. In our study, we have attempted to comparatively investigate the differential gene expressions of LDLR family in normal prostate epithelial cell line insert ignore into journalissuearticles values(RWPE-1);, prostate cancer cell line insert ignore into journalissuearticles values(DU145 cell line);, prostate cancer stem cells insert ignore into journalissuearticles values(DU145 CSCs); and non-CSCs insert ignore into journalissuearticles values(DU145 non-CSCs, bulk population);. Materials and Methods: Cancer stem cells in DU-145 prostate cancer cell line were isolated by flow cytometry according to CD133 and CD44 cell surface properties. Whole transcriptome sequencing data was comprehensively analyzed for each group. The protein-protein interaction network was determined using the STRING protein database. Results: Our data showed that the expression levels of LRP1, LRP3, LRP8 and LRP11 were increased in the DU145 CSCs relative to the normal prostate epithelial cell line. Conclusion: Overall, our data suggest that the LRP functions and/or the expression in prostate cancer may ultimately change the invasive phenotype of the CSCs.
