Project description:To explore the role of HIC1 deletion in regulating prostate cancer(PCa) microenvironment development, Human Gene Expression Microarrays were searched for altered genes upon HIC1 knockout expression in PC3 cells. According to fold-change screening between HIC1-knockout and its respective control cells, both up-regulated and down-regulated genes were shown.

Project description:This study aimed to further our understanding of the role that hypermethylatioted in cancer 1 (HIC1) plays in prostate cancer (PCa) development. Microarrays were searched for some genes that had correlated expression with HIC1 mRNA. Our data showed that HIC1 promoter hypermethylation was presented in cell lines, tissues and plasma of PCa patients. According to fold-change screening between restoring expression of HIC1 and its respective control cells, both up-regulated and down-regulated genes were commonly observed in PC3 and C4-2B cells. The restoring expression HIC1 in PCa lines were respectively noted as PC3-HIC1 and C4-2B-HIC1 cells, and the respective controls were noted as C4-2B-GFP and PC3-GFP cells.

Project description:To explore the role of HIC1 silencing in regulating PCa EMT development, Human Gene Expression Microarrays were searched for altered genes upon silencing HIC1 expression in C4-2B and DU145 cells. According to fold-change screening betweenHIC1-silenced and its respective control cells, both up-regulated and down-regulated genes were shown. Human PCa cell lines C4-2B and DU145 were transfected with lenti-virus (shRNA targeting HIC1 and respective control). HIC1-silenced cells were respectively noted as C4-2B-shHIC1 and DU145-shHIC1. Their respective control cells were respectively noted as C4-2B-shctrl and DU145-shctrl.

Project description:In order to address the putative role of MELK and UBE2C in prostate cancer development and progression, we performed functional analysis upon siRNA-based knockdown, and searched for downstream genes and processes by microarray experiments. RNAi-based inhibition of MELK and UBE2C was efficient in PC3 prostate cancer cells and decreased transcriptional level down to about 30% remaining expression level. Illumina microarray experiments were done upon siRNA based knockdown 48h after transfection of PC3 cells in triplicates.

Project description:Transcription factors are one of the major groups of proteins whose suppression leads to tumor growth arrest. Different types of cancer express a specific set of transcription factors that establish and maintain specific gene expression patterns. In prostate cancer cells, one of the key transcriptional regulators is the HOXB13 protein, but its function has not been well characterized. In the present study, we searched for protein partners of HOXB13 by co-immunoprecipitation followed by high-throughput mass spectrometric analysis (IP/LC-MS) using the PC3 cell line as a source. This analysis revealed that the major partners of HOXB13 were transcription factors with different types of DNA-binding domains.

Project description:BACKGROUND: Cancer stem-like cells are proposed to sustain solid tumors by virtue of their capacity for self-renewal and differentiation to cells that comprise the bulk of the tumor, and have been identified for a variety of cancers based on characteristic clonal morphologies and patterns of marker gene expression. METHODS: Single cell cloning and spheroid culture studies were used to identify a population of cancer stem-like cells in the androgen-independent human prostate cancer cell line PC3. RESULTS: We demonstrate that, under standard culture conditions, ~10% of PC3 cells form holoclones with cancer stem cell characteristics. These holoclones display high self-renewal capability in spheroid formation assays under low attachment and serum-free culture conditions, retain their holoclone morphology when passaged at high cell density, exhibit moderate drug resistance, and show high tumorigenicity in scid immunodeficient mice. PC3 holoclones readily form spheres, and PC3-derived spheres yield a high percentage of holoclones, further supporting their cancer stem cell-like nature. We identified one gene, FAM65B, whose expression is consistently up regulated in PC3 holoclones compared to paraclones, the major cell morphology in the parental PC3 cell population, and two genes, MFI2 and LEF1, that are consistently down regulated. This molecular profile, FAM65Bhigh/MFI2low/LEF1low, also characterizes spheres generated from parental PC3 cells. The PC3 holoclones did not show significant enriched expression of the putative prostate cancer stem cell markers CD44 and integrin α2β1. PC3 tumors seeded with holoclones showed dramatic down regulation of FAM65B and dramatic up regulation of MFI2 and LEF1, and unexpectedly, a marked increase in tumor vascularity compared to parental PC3 tumors, suggesting a role of cancer stem cells in tumor angiogenesis. CONCLUSIONS: These findings support the proposal that PC3 tumors are sustained by a small number of tumor-initiating cells with stem-like characteristics, including strong self-renewal and pro-angiogenic capability and marked by the expression pattern FAM65Bhigh/MFI2low/LEF1low. These markers may serve as targets for therapies designed to eliminate cancer stem cell populations associated with aggressive, androgen-independent prostate tumors such as PC3.
