Transcriptomic analysis of HCV+ vs HCV- hepatocytes and tumoral cells

HCV+ cells were detected by smiFISH on liver section of a patient with hepatocellular carcinoma. Clusters of HCV+ and HCV- cells were captured by laser microdissection and transriptomes analysed by RNA sequening. Highly sensitive single molecule fluorescent in situ hybridization applied to frozen tissue sections of a hepatitis C patient allowed the delineation of clusters of infected hepatocytes. Laser micro-dissection followed by RNAseq analysis of HCV-positive and -negative regions from the tumoral and non-tumoral tissues from the same patient revealed HCV-related deregulation of expression of genes in the tumor and in the non-tumoral tissue. Overall design: mRNA profiles of clusters of cells HCV+ or HCV- from one patient were generated by deep sequencing using Illumina HiSeq2000.
