This book was released on 2014-11-10 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies have shown that alterations of epigenetics and microRNAs (miRNAs) play critical roles in the initiation and progression of human cancer. Epigenetic silencing of tumor suppressor genes in cancer cells is generally mediated by DNA hypermethylation of CpG island promoter and histone modification such as methylation of histone H3 lysine 9 (H3K9) and tri-methylation of H3K27. MiRNAs are small non-coding RNAs that regulate expression of various target genes. Specific miRNAs are aberrantly expressed and play roles as tumor suppressors or oncogenes during carcinogenesis. Important tumor suppressor miRNAs are silenced by epigenetic alterations, resulting in activation of target oncogenes in human malignancies. Stem cells have the ability to perpetuate themselves through self-renewal and to generate mature cells of various tissues through differentiation. Accumulating evidence suggests that a subpopulation of cancer cells with distinct stem-like properties is responsible for tumor initiation, invasive growth, and metastasis formation, which is defined as cancer stem cells. Cancer stem cells are considered to be resistant to conventional chemotherapy and radiation therapy, suggesting that these cells are important targets of cancer therapy. DNA methylation, histone modification and miRNAs may be deeply involved in stem-like properties in cancer cells. Restoring the expression of tumor suppressor genes and miRNAs by chromatin modifying drugs may be a promising therapeutic approach for cancer stem cells. In this Research Topic, we discuss about alterations of epigenetics and miRNAs in cancer and cancer stem cell and understand the molecular mechanism underlying the formation of cancer stem cell, which may provide a novel insight for treatment of refractory cancer.

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.
Download or read book MicroRNA Targeted Cancer Therapy written by Fazlul H. Sarkar and published by Springer Science & Business. This book was released on 2014-04-22 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the discovery of microRNAs (miRNAs) some twenty years ago by Victor Ambros, David Baulcombe and Gary Ruvkun, these three scientists worked to uncover the mystery of miRNA, the small segments of nucleotides that silence genes. While studying the development of the nematode worm, Ambros and Ruvkun discovered miRNA in animals, while Baulcombe discovered it in plants. Since their discovery, it took more than two decade to fully appreciate the value of miRNA in human health and diseases. Emerging evidence suggest that the activation of oncogenes and/or the inactivation of tumor suppressor genes contribute to the development and progression of tumors. The regulation of genes is by far controlled by many transcription factors which are often deregulated during the development and progression of cancer. In addition, emerging evidence clearly suggests that the deregulation of miRNAs or small non-coding RNAs could also regulate the expression of genes and likewise, miRNA genes are also regulated by transcription factors. The most attractive feature of miRNAs is that one miRNA can regulate many target genes (mRNAs) and thus miRNA targeted therapy is highly promising because multiple genes could be regulated by targeting a single miRNA, which becomes very important for the killing of highly heterogeneous populations of cancer cells within a tumor mass. Therefore, miRNA targeted therapy is an attractive attribute of miRNA research, which is covered through eighteen chapters complied in this book “MicroRNA targeted Cancer therapy” and it is hoped that the field of miRNA research will be appreciated through critical reading of these chapters on the cutting-edge research on miRNAs.

Download or read book MicroRNA in Development and in the Progression of Cancer written by Shree Ram Singh and published by Springer. This book was released on 2016-09-03 with total page 0 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.
Download or read book MicroRNAs in Development and Cancer written by Frank J. Slack and published by World Scientific. This book was released on 2011 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: MicroRNAs have recently emerged as key regulators of gene expression during development and are frequently misexpressed in human disease states, in particular cancer. These 22-nucleotide-long transcripts act to promote or repress cell proliferation, migration and apoptosis during development, all of which are processes that go awry in cancer. Thus, microRNAs have the ability to behave like oncogenes or tumor suppressors. In addition, their small size and molecular properties make them amenable as targets and therapeutics in cancer treatment. This book goes into detail on how microRNAs represent a paradigm shift in thinking about gene regulation during development and disease, and provide the oncologist with a potentially powerful new battery of agents to diagnose and treat cancer.

Download or read book Dysregulated MicroRNA Expression Contributes to Emergence of Cancer Stem Cell Subpopulations in Human Colorectal Cancers written by Victoria A. Stark and published by . This book was released on 2022 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: MicroRNAs (miRNAs) have a role in the regulation of different biological pathways in the body. Dysregulation of these noncoding fragments can lead to disease, developmental defects, and various cancer types. In this study we investigate the miRNAs that are implicated to target genes that encode different stem cell (SC) genes during tumorigenesis of colorectal cancer (CRC). CRC is one of the leading causes of cancer-related death in the United States. One possible reason behind the lack of efficacy in cancer drug therapeutics might be the result of the tumor heterogeneity, as proposed by the Big Bang Model of cancer heterogeneity. Previous research has been done to track the colonic SCs present at the bottom of colonic crypts during tumorigenesis. The Boman research team demonstrated that aldehyde dehydrogenase1 (ALDH1) is a specific biomarker for tracking colonic SCs (SCs), and that SC overpopulation drives CRC development and growth. They also found that CRC contains multiple cancer SC (CSC) subpopulations. Other essential biomarkers include LRIG1, LGR5, and CD166 and it was postulated they mark different CSC subpopulations in the emergence of tumor heterogeneity in CRC. The gap in our knowledge is that we do not know what causes tumor heterogeneity. The research objective is to investigate whether the different miRNAs target the CSC genes in each of the CSC subpopulations. Hypothesis: Specific miRNAs target the different CSC subpopulations (LRIG1, ALDH, LGR5, and CD166) which leads to multiple CSC subpopulations that establishes intra-tumoral heterogeneity in CRCs. Specific Aims: Aim 1: To analyze the different cancer stem cell (CSC) subpopulations using flow cytometry. Aim 2: To determine the expression of miRNAs in each CSC subpopulation and identify the mRNAs predicted to be targeted by the upregulated miRNAs. Aim 3: To determine the plasticity of ALDH and LGR5 CSC subpopulations from HT29 cells by growing them in 3D cultures to see if the subpopulations interconvert and if the miRNA signatures remain unchanged. Accordingly, different CSC sub-populations were isolated using fluorescence activated cell sorting (FACS), differential expression of miRNAs between CSC subpopulations was measured using NanoString profiling, and mRNAs targeted by the miRNAs as well as their enriched functional-related mRNA groups was identified using bioinformatics analysis. My results depict 4 different subpopulations when running the CSC combination sorts between ALDH, LGR5, LRIG1, and CD166. I quantified different percentages of the CSC genes in their respective combination sorts via flow cytometry. Moreover, I determined the expression of miRNAs and predicted, using bioinformatics analyses, their respective mRNA targets for the CSC subpopulations. The LGR5/ALDH sort resulted in 326 significant miRNAs of interest. Thus, I focused on LGR5 and ALDH CSCs to assess cell plasticity studies because LGR5 and ALDH have major roles in CRC progression. In conclusion, the presence of multiple subpopulations and different mRNA targets provides a mechanism that explains how intra-tumor heterogeneity arises in CRC. It also illustrates that CRC is highly complex in its different miRNA and mRNA targets. This study is significant as we aim to understand tumor heterogeneity through miRNA dysregulation and how to therapeutically target CSC populations.
