Download or read book Involvement of MicroRNAs in the Development of Androgen Independent Prostate Cancer written by Richard James Ottman and published by . This book was released on 2016 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study, the association of genome wide miRNA expression (1113 unique miRNAs) with development of resistance to ADT was determined. Androgen sensitive prostate cancer cells that progressed to ADT and AR antagonist Casodex (CDX) resistance upon androgen withdrawal and treatment with CDX were used. Validation of expression of a subset of 100 miRNAs led to identification of 43 miRNAs that are significantly altered during progression of cells to treatment resistance. A correlation of altered expression of 10 proteins targeted by some of these miRNAs in these cells was shown.
Book Synopsis Identification of Dysregulated MiRNA Targets in Human Prostate Cancer by : Po-hsun Chen
Download or read book Identification of Dysregulated MiRNA Targets in Human Prostate Cancer written by Po-hsun Chen and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: MicroRNAs (miRNAs) are small, non-coding RNAs (18~24 nt) that regulate diverse cell functions in mammalian cells, including proliferation, differentiation, metabolism, stress resistance, and death. There is increasing evidence that altered expression and function of regulatory miRNAs contribute to the uncontrolled growth of human cancers. We examined the hypothesis that miRNA expression profiles can distinguish malignant from normal tissues. With the use of high throughput, liquid phase hybridization analyses (mirMASA) were carried out with 40 Stage 1c/2 prostate cancer specimens, using 114 miRNA-specific probes. We identified 5 miRNAs (miR -23b, -100, -145, -221, and -222) that were significantly downregulated in malignant prostate tissues as compared with their normal counterpart from the same patient. Decreased expression was confirmed by quantitative real-time PCR (qRT-PCR) analyses. The pathophysiological role of these downregulated miRNAs was further characterized in the prostate cancer LNCaP cell line, which exhibited similarly reduced expression of miR- 23b, -145, -221, and -222. Ectopic expression of mature miR-23b and miR-145 reduced LNCaP cell growth by>40%. In contrast, transfection with a miRNA (miR-141) that was upregulated did not markedly affect cancer cell growth. The altered expression of miR- 145 was of particular interest, in view of its similarly reduced expression in breast, cervical, colon, and lung carcinomas. In silico search (TargetScan) yielded 396 eligible targets for miR-145, of which 6 were markedly upregulated in LNCaP cells. These include the prostaglandin F receptor (PTGFR), transforming growth factor (TGFBR2), p21-activated kinase 7 (PAK7), SLIT-ROBO Rho GTPase activating protein 2 (SRGAP- 2), kinesin family member 3A (KIF3A), and Ras association (RalGDS/AF-6) domain family 2 (RASSF2). miR-145 was uniformly downregulated in all prostate caner lines tested (LNCaP, 22Rv1, PC-3, Du-145, as compared with the nonmalignant prostate line RWPE-1) This miRNA may be differentially expressed in androgen dependent (AD) and androgen independent (AI) prostate cancer cell lines according to qPCR analysis. Mean expression level of miR-145 was approximately 6-fold lower in AD (LNCaP, 22Rv1) than AI (PC3, Du-145) lines. qPCR analysis suggests that PTGFR and RASSF2 were upregulated in 3 of 4 prostate cancer cell lines, whereas MYCN was only upregulated in androgen independent cell lines. The expression of CCND2, MAP3K3 and MAP4K4 were not significantly upregulated by qPCR analysis. These findings suggest that altered miR-145 expression may impact prostate cancer growth through its loss of regulation of PTGFR and/or RASSF2 activities. qPCR analysis of miR-145 treated prostate cancer cells showed decreased expression of PTGFR and RASSF2 indicating these two genes are potential targets of miR-145 modulation. Direct binding only showed moderate reduction of RASSF2 and a more pronounced reduction of PTGFR. These studies suggest that miR-145 may modulate prostate cancer cell growth by modulating PTGFR activity.

Book Synopsis MicroRNA in Development and in the Progression of Cancer by : Shree Ram Singh
Download or read book MicroRNA in Development and in the Progression of Cancer written by Shree Ram Singh and published by Springer Science & Business. This book was released on 2014-04-21 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: miRNAs are a class of endogenous, small non-protein coding RNA molecules (~ 22 nucleotides) which are novel post-transcriptional regulators of gene expression. Since we have hundreds of miRNAs, the major challenge is now to understand their specific biological function. In fact the experimental evidence suggests that signaling pathways could be ideal candidates for miRNA-mediated regulation. Several studies suggest that miRNAs affect the responsiveness of cells to signaling molecules such as WNT, Notch, TGF-β and EGFR. Altered expression of particular miRNAs has been implicated in the onset and development of cancer and could be used as potential biomarkers for the disease. Recently, many studies have found miRNAs have crucial regulatory roles in Cancer stem cells (CSCs) a kind of tumor initiating cells (TICs) and dormancy. Findings also suggest that DNA methylation may be important in regulating the expression of many miRNAs in several cancer initiating cells. Several miRNAs are known to either upregulated or downregulated in CSCs when compared to non-cancerous cells from the same tissues. CSCs are a small subpopulation of cells identified in a variety of tumors and involve in self-renewal, differentiation, chemoresistance and tumorigenesis. The volume will give a comprehensive account of important advancements in the area of miRNAs and cancer.

Book Synopsis Mirnas as Biomarkers for Prostate Cancer Progression by : Gene C. Clark
Download or read book Mirnas as Biomarkers for Prostate Cancer Progression written by Gene C. Clark and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Prostate cancer is one of the most challenging global medical issues today. In 2011, prostate cancer was the most diagnosed malignancy in the United States, making up 29% of new cancer cases. In that year it was the second leading cause of cancer related deaths among men in the USA and the second most common cause of cancer related death overall from the EU. The prostate remains, however, an under studied organ, making insights into the anatomy and biology of prostate cancer difficult to achieve. After 30 years, PSA screening of men of the appropriate age is still the first step in prostate cancer diagnosis, usually followed by a manual prostate exam which may lead to a transrectal biopsy. This study makes use of Next Generation Sequencing to successfully identify a superior miRNA based urinary assay for the detection of prostate cancer. A receiver operating curve AUC of 0.90 was achieved for patients vs. non-patients using an additive risk model defined by empirically derived critical threshold values of eight urinary miRNAs identified with this method. This is superior to the PSA blood test's AUC of 0.66 which illustrates that a miRNA profile such as this has the potential to surpass protein biomarkers such as PSA in terms of specificity and sensitivity. It was also demonstrated that a geometric mean of three urinary miRNAs were useful for endogenous normalization. One significant risk factor for prostate cancer is being African American. Again using Next Generation Sequencing technology, we have established a miRNA expression profile for the stages of a prostate cancer cell line progression model derived from the normal prostate epithelium of an African American man. Normal prostate epithelium was immortalized only with SV40 large T antigen (P69) and passaged three times in nude mice, producing the highly aggressive and metastatic M12 cell line. The M2182 cell line is an intermediate between the P69s and M12s having only been passaged twice and not yet having acquired metastatic potential. The F6 cell line was derived by reintroducing a copy of chromosome 19 missing from the M12 cell line via microcell mediated chromosome transfer. These profiles show a large downregulation of miRNAs early in tumorigenesis (from P69 toM2182) affecting the DLK1-DIO3 megacluster and the miR-200 family. The later acquisition of metastatic potential (from M2182 to M12) is concomitant with the upregulation of specific miRNAs including the HOX gene miRNAs miR-10a and miR-196 and miR-9. Thus, the analysis of this progression model has uncovered relevant miRs and genes the dysregulation of which contribute to prostate tumorigenesis.
Book Synopsis MicroRNAs: Key Regulators of Oncogenesis by : Sadegh Babashah
Download or read book MicroRNAs: Key Regulators of Oncogenesis written by Sadegh Babashah and published by Springer. This book was released on 2014-07-08 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aberrant expression and function of microRNAs (miRNAs) in cancer have added a new layer of complexity to the understanding of development and progression of the disease state. It has been demonstrated that miRNAs have a crucial function in oncogenesis by regulating cell proliferation and apoptosis as oncogenes or tumor suppressors. The expression signatures of miRNAs provide exciting opportunities in the diagnosis, prognosis and therapy of cancer. Since miRNAs can function as either oncogenes or tumor suppressor genes in oncogenesis, the potential of using these small RNAs as therapeutic targets opens up new opportunities for cancer therapy by either inhibiting or augmenting their activity.

Book Synopsis Combinatorial Analysis of Tumorigenic MicroRNAs Driving Prostate Cancer by : William Thomas Budd
Download or read book Combinatorial Analysis of Tumorigenic MicroRNAs Driving Prostate Cancer written by William Thomas Budd and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Prostate cancer is the leading non-cutaneous malignancy affecting men in the United States. One in every six men will be affected by prostate cancer. Due to the high incidence of prostate cancer, there is a need to develop biomarkers capable of identifying tumors from benign prostatic lesions. miRNAs are small molecules that regulate protein translation and impact cellular integrity when dysregulated. It is widely thought that miRNAs have the potential to serve as biomarkers. This study utilizes a unique combinatorial analysis of miRNA dysregulation to identify key miRNAs involved in prostate tumor initiation, progression and metastasis. Numerous dysregulated miRNAs potentially influence cancer development. A unique bioinformatically driven, network based approach was used to rank potential miRNAs that drive tumor progression. This study showed that miRNAs preferentially regulate highly connected proteins and transcription factors that affect numerous downstream targets. Thus dysregulation of a single highly connected miRNA could severely impact homeostatic maintenance of the tissue. In combination with miRNA profiling of a cancer cell progression model, the utilization of laser captured microdissection was used to separate cancer specific microRNA portraits from background differences arising from stroma cells, lymphocytes, and remaining normal epithelial cells. Integration of miRNA profiles with information gathered using networks biology and targeted proteomics resulted in the identification of a key miRNA that affects prostate cancer development and may be useful as a novel biomarker for identification/ staging of prostate cancer. Human miR-125b was identified as a potential miRNA suppressor of tumor formation. Previous work has identified miR-125-b as the post-transcriptional regulator of the ErbB2/ ErbB3 growth factor receptor family. Loss of miR-125b drives up expression of ErbB2/ ErbB3 activating downstream PI3K/AKT and RAS oncogene pathways. The level of miR-125b decreases 3-5-fold between benign and tumor epithelium. Further, miR-125b decreases during the development of prostatic intraepithelial neoplasia, which is regarded as an early indicator of prostate cancer. Thus miR-125b may be an ideal marker of early changes indicative of cancer. Restoration of miR-125b into highly tumorigenic, metastatic cells reduces mobility and invasion of underlying tissues. Taken together these data show miR-125b is a tumor suppressor in the healthy prostate.
