Project description:Expression profiling of Xenografts of Hepatocellular Carcinoma Keywords: Human Cancer Briefly, primary HCCs obtained during liver resection were minced into fine fragments capable of passing through an 18-gauge needle, mixed in a 1:1 (v/v) ratio with Matrigel (Collaborative Research, Bedford, MA) and injected in the subcutaneous flanks of 8-week-old male severe combined immune deficient (SCID/SCID, The Jackson Laboratory, Harbor, ME) mice. Six to eight mice were injected for each primary tumor. Growth of established tumor xenografts was monitored twice weekly by vernier caliper measurement of tumor length (a) and width (b), and tumor volume was calculated as (a x b2) / 2. Serial passages of xenograft lines were obtained by dissecting tumors from sacrificed animals and reinjecting the dissociated tumor cells into successive generations of SCID mice as described above. Seven xenograft lines were studied in this report (2-1318, 5-1318(1), 5-1318(3), 2006, 26-1004, 26-1004(cirr), and 30-1004). Xenografts 2-1318 and 5-1318(1) were derived from Hep B-positive patients.

Project description:Background: It is a challenge to identify those patients who, after undergoing potentially curative treatments for hepatocellular carcinoma, are at greatest risk of recurrence. Such high-risk patients could receive novel interventional measures. An obstacle to the development of genome-based predictors of outcome in patients with hepatocellular carcinoma has been the lack of a means to carry out genomewide expression profiling of fixed, as opposed to frozen, tissues. Methods: We aimed to demonstrate the feasibility of gene-expression profiling of more than 6000 human genes in formalin-fixed paraffin-embedded tissues. We applied the method to tissues from 307 patients with hepatocellular carcinoma, from four series of patients, to discover and validate a gene-expression signature associated with survival. Results: The expression-profiling method for formalin-fixed, paraffin-embedded tissue was highly effective: samples from 90% of the patients yielded data of high quality, including samples that had been archived for more than 24 years. Gene-expression profiles of tumor tissue failed to yield a significant association with survival. In contrast, profiles of the surrounding nontumoral liver tissue were highly correlated with survival in a training set of 82 Japanese patients, and the signature was validated in tissues from an independent group of 225 patients from the United States and Europe (p = 0.04). Conclusions: We have demonstrated the feasibility of genomewide expression profiling of formalin-fixed, paraffin-embedded tissues and have shown that a reproducible gene-expression signature correlating with survival is present in liver tissue adjacent to the tumor in patients with hepatocellular carcinoma. This SuperSeries is composed of the following subset Series: GSE10140: Gene Expression in Fixed Tissues and Outcome in Hepatocellular Carcinoma (Training Set, Liver) GSE10141: Gene Expression in Fixed Tissues and Outcome in Hepatocellular Carcinoma (Training Set, HCC) GSE10142: Gene Expression in Fixed Tissues and Outcome in Hepatocellular Carcinoma (Validation Set) Keywords: Hepatocellular carcinoma, Expression array, Illumina, Signatures, Outcome prediction Training cohort: 80 tumor and 82 non-tumor liver tissues surgically resected from patients with hepatocellular carcinoma (HCC); Validation cohort: 225 non-tumor liver tissues surgically resected from patients with HCC. Clinical data has been withheld from GEO due to privacy concerns.
