ArrayCGH of human hepatocellular carcinoma (HCC)

ABSTRACT: We used array-based comparative genomic hybridization (arrayCGH) of 76 hepatocellular carcinomas (HCCs) to search for genetically disrupted genes. Seventy-six HCC clinical specimens were analyzed. Genomic DNA of the tumor sample was labeled with Cy5 and reference normal DNA (Promega) was labeled with Cy3.

Hepatocellular carcinoma (HCC)

Project description:BACKGROUND & AIMS: Expression of microRNAs (miRNAs) in metastatic foci of hepatocellular carcinoma (HCC) is unknown. We identified metastasis-related miRNAs in recurrent cases after living donor liver transplantation (LDLT). Methods: We performed a comprehensive analysis of primary HCC (T), noncancerous liver (N), and resected recurrent (metastatic) HCC (M) using microarray analyses to identify metastasis-related miRNAs in in three patients with post-transplant recurrence. The RNA samples from three cases that underwent resection of recurrences after LDLT were made available for miRNA microarray analysis. The three cases included a 57-year-old man (case 1) with peritoneal recurrence and infected by hepatitis B virus (HBV), and a 48-year-old woman (case 2) and a 51-year-old man (case 3) with lung recurrences and hepatitis C virus (HCV) infection. Microarray analysis was performed for each RNA sample from the (T), (N) in the explanted liver, and (M). A sample containing equal amounts of RNAs from histologically normal livers of three living donors (NL: normal liver) was analyzed as a control.

Gut Microbiota in People With Hepatocellular Carcinoma (HCC)

Project description:Background: There are about 100 trillion microbial cells in a person s gut. This is called the human gut microbiota. When this is disrupted, it can lead to many diseases. Studies show that the gut microbiota in people with cancer is different than that found in healthy people. Researchers want to study links between the gut microbiota and the immune system in people with a liver disease called hepatocellular carcinoma (HCC). Objective: To study links between gut microbiota and the immune system in people with HCC. Eligibility: People at least 18 years old with HCC. They must be scheduled to have tumors removed by surgery. Design: * People having surgery for primary liver tumors at the Mount Sinai Medical Center will be screened for this study. * At the initial visit, blood, rectal swabs, urine, and stool will be collected. Participants will answer questions about their medical condition. * Before surgery, blood, rectal swabs, urine, and stool will be collected. This will be done at a routine visit. * When they have surgery, a piece of liver tissue with the tumor will be collected. This will be sent to the National Cancer Institute for tests. * After surgery, blood, rectal swabs, urine, and stool will be collected 3 times. This will be done at routine visits.

Proteomic characterization of human hepatocellular carcinoma (HCC) tumor biopsies

Project description:We analyzed the proteome of tumor and matched non-tumor biopsies from 51 treatment-naive Hepatocellular carcinoma (HCC) patients by DIA (SWATH). Thereby we aim to find subgroups of patients characterized by specific pathway activation. Furthermore, we aim to find novel factors involved in HCC development and novel biomarkers.

Phospho-proteomic characterization of human hepatocellular carcinoma (HCC) tumor biopsies

Project description:We analyzed the phospho-proteome of tumor and matched non-tumor biopsies from 51 treatment-naive Hepatocellular carcinoma (HCC) patients by label-free DDA. Thereby we aim to find subgroups of patients characterized by specific pathway activation. Furthermore, we aim to find novel factors involved in HCC development and novel biomarkers.
