MicroRNA Dysregulation in Human Prostate Cancer Cell Model (M12 and P69)

ABSTRACT: An isogenic prostate cancer cell model was used to profile miRNA changes that contribute to the tumorigenic state of prostate cancer. P69 cells are an SV40 large T antigen immortalized cell line that is poorly tumorigenic and non-metastatic. The M12 derivative was derived from an in vivo selection process using nude, athymic mice. Immortalized cells were cultured and used to extract RNA and probed against the human miRNA panel from Exiqon. There were a total of 186 miRNAs that were at least two fold differentially regulated .

Two human prostate cancer cell lines were used to evaluate miRNA expression differences contributing to oncogenesis. Two replicates were performed and the data presented as the mean fold difference between P69 and M12.

Gene expression signature of EGR3 silencing in M12 human prostate cancer cells

Project description:EGR3 expression is upregulated in human prostate cancer compared to normal prostate tissue and is associated with absence of relapse, while low EGR3 expression in tumors is predicitive of disease relapse (Pio et al., PLOS One 2013; 8(1):e54096). However the function of EGR3 in prostate cancer is unknown. Human prostate cancer cells M12 containing high levels of EGR3 were used for shRNA-mediated silencing of EGR3. Gene expression analysis of EGR3 knockdown cells reveals a role in inflammation and the existence of a crosstalk with the NFkB pathway. The M12 prostate cancer cell line is a tumorigenic derivative of the P69 SV40-T immortalized epithelial cells obtained through serial passages of P69 tumor xenografts in mice (Bae et al., Prostate 1998; 34:275-82). M12 cells were transfected with shRNA scramble plasmid (shSCR) or shEGR3 plasmid and selected with puromycin (1 μg/ml). Single-cell clones were isolated using standard methods. Stably transfected cells (shSCR-M12 and shEGR3-M12) were then maintained in growth medium supplemented with puromycin. Two separate clones (termed cl 2 and cl 3) were studied. Knockdown of EGR3 (50% efficacy on average) was stable over many cell culture passages. Biological duplicates of control cells (scramble shRNA) and of two separate clones of shEGR3 cells (clone 2 and clone 3) were used for the gene expression arrays (i.e. 6 samples).

miRNA high-throughput sequencing of human prostate cancer cell lines P69, M12, M2182

Project description:Purpose: Next-generation sequencing (NGS) of miRNA expression in cancer cell lines provides a path for analysis of dysregulated pathways and potential treatment of dysregulation. The goals of this study are to compare NGS-derived miRNA expression data in a non-tumorigenic prostate cell line (P69) to its metastatic derivative cell lines M12 and M2182.

Transcription profiling of human breast tumor epithelia cell types HMLER and BPLER compared to immortalized parent cells of origin - HME and BPE

Project description:The gene expression of two different tumorigenic human breast epithelial cell types (HMLER and BPLER) is compared with their immortalized parental cell-of-origin (HME and BPE). Experiment Overall Design: Two different normal primary human mammary epithelial cell populations (BPECs and HMECs) were isolated based on their differing in vitro growth requirements. These cells were immortalized by hTERT giving rise to BPE and HME cells. These hTERT immortalized cells (BPE and HME) were transformed by SV40-early region (LT+st) and H-Ras giving rise to transformed tumorigenic derivatives BPLER and HMLER. Biological replicates (4 - 6 samples) for each of 4 cell types were analyzed (untransformed hTERT immortalized cell populations (BPE&HME), and transformed tumorigenic derivatives (BPLER & HMLER).

Functional and evolutionary significance of human microRNA seed region mutations [M12]

Project description:MicroRNAs (miRNAs) are small non-coding RNAs that play a central role in the regulation of gene expression at the post transcriptional and/or translational level thus impacting various biological processes. Dysregulation of miRNAs could affect processes associated with progression of a variety of diseases including cancer. Majority of miRNA targeting in animals involves a 7-nt M-bM-^@M-^\seed regionM-bM-^@M-^] mapping to positions 2-8 at the moleculeM-bM-^@M-^Ys 5' end. The importance of this 7 nt sequence to miRNA function is evidenced by the fact that the seed region sequence of many miRNAs is highly conserved within and between species. In this study, we computationally and experimentally explore the functional significance of sequence variation within the seed region of human miRNAs. Our results indicate that change of a single nt within the 7-nt seed region changes the spectrum of targeted mRNAs significantly meanwhile further nt changes have little to no additional effect. This high functional cost of even a single nucleotide change within the seed region of miRNAs explains why the seed sequence is highly conserved among many miRNA families both within and between species and could help clarify the likely mechanisms underlying the evolution of miRNA regulatory control. mRNAs were collected from 3 M12 miRNA treated and 3 negative control miRNA treated HEY ovarian cancer cell samples. mRNA expression was captured on Affymetrix U133 Plus 2 chips. To compare mRNA expression pattern between the M12 treated cells and the negative control treated cells, present/absent calls were generated using MAS5, while signals were calculated using GCRMA and then log2 transformed. Expression of differentially expressed genes or down regulated miRanda-mirSVR predicted miRNA target genes was compared between miRNA treated samples.
