Transcription profiling of human hepatocellular carcinomas to investigate HOX A13 expression

ABSTRACT: HOX A13 over expression represents: i) a novel molecular marker of hepatocellular carcinomas; ii) a sign of epithelial-endothelial transition accounting for tumor independent angiogenesis and lymphangiogenesis. Experiment Overall Design: Genomic analysis of high HOX A13 expressing pairs (HCC/non tumorous liver tissues) to investigate the molecular mechanisms responsible for the increased expression of HOX A13 in liver cancers and to identify potential HOX A13 targets.

Transcription profiling of human hepatocellular carcinomas

Project description:Gene expression profile of Human hepatocellular carcinoma were investigated with spotted cDNA microarray technology. Tumor and non-tumorous region used this experiment were hybridization with normal liver total RNA in same cDNA chip, respectivly. All tests were accompanied with dye-swap normalization.

Identification of microRNAs specifically expressed in HCV-associated hepatocellular carcinoma

Project description:Background: Several studies have investigated the association of miRNAs with hepatocellular carcinoma (HCC) but the data are not univocal. Methods: We performed a microarray study of miRNAs in hepatitis C virus (HCV)-associated HCC and other liver diseases and healthy conditions. Results and Conclusions: The simultaneous comparison of different liver diseases and normal livers allowed the identification of 18 miRNAs exclusively expressed in HCV-associated HCC, with sensitivity and specificity values of diagnostic-grade. A total number of 76 liver specimens obtained from 43 patients were analyzed: 26 liver specimens obtained from 10 patients with HCV-associated HCC, including 9 specimens from the tumor area (HCC) and 17 specimens from the surrounding non-tumorous tissue affected by cirrhosis (HCC-CIR); 18 specimens from 10 patients with HCV-associated cirrhosis without HCC (CIR); 13 specimens from 4 patients with HBV-associated acute liver failure (ALF); 12 specimens from 12 liver donors (LD); and 7 from normal liver of 7 subjects who underwent hepatic resection for liver angioma (NL).

Hepatocellular carcinomas (HCC) in mice transduced in utero with feline immunodeficiency virus-based vectors (expression)

Hepatocellular carcinomas (HCC) in mice transduced in utero with feline immunodeficiency virus-based vectors (expression)

Project description:Fetal mice (16 days gestation) were administered feline immunodeficiency virus (FIV)-based lentiviral viral particles containing the gene encoding GFP. Six liver tumors developed in three mice between the ages of 273 and 484 days, each mouse developed 2 tumors. These tumors and non-tumorous liver tissue from the same animals and animals that did not develop tumors and untransduced controls were harvested and microarrays were performed on total RNA extracted from these samples. We were interested in investigating the link between lentiviral integration and gene expression. Keywords: Comparison of HCC with non-tumorous liver tissue adjacent to tumor. Fourteen samples were analyzed in total: Two tumors from each of three mice (6 samples); surrounding non-tumorous liver tissue from each of these three mice (3 samples); two female mice and one male mouse that were transduced and did not develop tumors (3 samples); one female and one male untransduced mouse (2 samples). The samples were performed in two runs: one containing the samples from female mice and the second containing samples from male mice.

Hepatocellular carcinomas (HCC) in mice transduced in utero with feline immunodeficiency virus-based vectors (CGH)

Project description:Fetal mice (16 days gestation) were administered FIV-based lentiviral viral particles containing the gene encoding EGFP. Six liver tumors developed in three mice (1 male, 2 females) between the ages of 273 and 484 days, each mouse developed 2 tumors. These tumors and non-tumorous liver tissue from the same animals were harvested and aCGH was performed on genomic DNA extracted from these samples. We were interested in investigating the link between lentiviral integration and chromosomal aberrations. Two tumors from each mouse (1 male, 2 females) were each compared to non-tumorous tissue surrounding the tumors.

Transcription profiling of tumorous and non tumorous live from Parkin-/- mice suggestsa role for Parkin as a tumor suppressor gene for hepatocellular carcinoma

Project description:To provide an insight into the molecular mechanism by which parkin deficiency contributes to hepatocarcinogenesis, we analyzed gene expression profiles of nontumorous and tumorous liver tissues from parkinâ/â mice using cDNA microarray analyses. Experiment Overall Design: We analysed the up and down regulated genes in tumorous and non-tumorous liver tissues of parkin-/- mice compared with normal liver tissues of wild-type mice.

Gene expression profiling of 18 hepatocellular carcinoma and adjacent non-tumorous liver tissue

Project description:These paired HCC and non-tumorous liver tissues were used to determine highly differentially expressed genes in HCC and non-tumorous liver tissue. Hepatocellular carcinoma (HCC) is a malignancy with poor survival outcome. Genes showing extreme differential expression between paired human HCC and adjacent non-tumorous liver tissue were investigated. PLVAP was identified as a gene specifically expressed in vascular endothelial cells of HCC but not in non-tumorous liver tissues. This finding was confirmed by RT-PCR analysis of micro-dissected cells and immunohistochemical staining of tissue sections. A recombinant monoclonal anti-PLVAP Fab fragment co-expressing extracellular domain of human tissue factor (TF) was developed. The potential therapeutic effect and toxicity to treat HCC were studied using a Hep3B HCC xenograft model in SCID mice. Infusion of recombinant monoclonal anti-PLVAP Fab-TF into the tumor feeding artery induced tumor vascular thrombosis and extensive tumor necrosis at doses between 2.5 µg and 12 µg. Tumor growth was suppressed for 40 days after a single treatment. Systemic administration did not induce tumor necrosis. Little systemic toxicity was noted for this therapeutic agent. The results of this study suggest that anti-PLVAP Fab-TF may be used to treat HCC cases for which transcatheter arterial chemoembolization (TACE) is currently used, but without major drawbacks of TACE. Anti-PLVAP Fab-TF may improve therapeutic outcome and be a viable therapeutic agent in patients with more advanced disease and compromised liver function. Frozen hepatocellular carcinoma and adjacent non-tumorous liver tissues were used for gnee expression profiling study. Affymetrix U133A genechips were used for gene expression profiling. This dataset is part of the TransQST collection.

Transcriptome evidence provides insight into Hox gene regulating rolling behavior in oniscidea

Project description:Behavior of rolling in oniscidea species had been reported as a sign to protect themselves to increase their survival rates, but the molecular mechanisms of rolling behaviors were still largely unknown. So we deeply characterized the molecular differences in rolling oniscidea samples and stretching oniscidea samples by transcriptome sequencing strategy (RNA-seq). Bulk RNA sequencing was performed with rolling and streching oniscidea samples. And our study suggests that Hox genes' expression levels could play an essential role in regulating neuron system development in oniscidea animals.
