Genomic instability is a hallmark of cancer. Inducing severe DNA damage and augmenting apoptosis to destroy cancer cells is thus a major chemotherapy approach, specifically for Triple Negative Breast Cancer cell (TNBC cell). We have uncovered a previously unrecognized role for a specific long non-coding RNA 152 (lncRNA152) induced by DNA damage reagent and function in protect genome stability, significantly overexpressed in TNBC cell. Our studies provide preliminary data that lncRNA152 overexpressed in TNBC cell and could potentially serve as a TNBC diagnostic biomarker. Also, lncRNA152-depleted cells are hypersensitive to the DNA damage inducer induced by the topoisomerase II inhibitor doxorubicin. lncRNA152 expression levels increase in response to DNA damage and are significantly higher in TNBC. We conclude that lncRNA152 could serve as a TNBC diagnostic biomarker and protects TNBC cells from DNA damage, perceptively providing a powerful approach to improve chemotherapy response.

The discovery of microRNA (miRNA) involvement in cancer a decade ago, and the more recent findings of long non-coding RNAs in human diseases, challenged the long-standing view that RNAs without protein-coding potential are simply “junk” transcription within the human genome. These findings evidently changed the dogma that “DNA makes RNA makes protein” by showing that RNAs themselves can be essential regulators of cellular function and play key roles in cancer development. MiRNAs are evolutionarily conserved short single-stranded transcripts of 19–24 nucleotides in length. They do not code for proteins, but change the final output of protein-coding genes by regulating their transcriptional and/or translation process. Ultraconserved genes (UCGs) are non-coding RNAs with longer length (>200bp) that are transcribed from the ultraconserved genomic region. Both miRNAs and UCGs are located within cancer-associated genomic regions (CAGRs) and can act as tumor suppressors or oncogenes. In this chapter, we present principles and concepts that have been identified over the last decade with respect to our understanding of the function of non-coding RNAs, and summarize recent findings on the role of miRNAs and UCGs in cancer development. Finally, we will conclude by discussing the translational potential of this knowledge into clinical settings such as cancer diagnosis, prognosis and treatment.

Genome Stability: From Virus to Human Application, Second Edition, a volume in the Translational Epigenetics series, explores how various species maintain genome stability and genome diversification in response to environmental factors. Here, across thirty-eight chapters, leading researchers provide a deep analysis of genome stability in DNA/RNA viruses, prokaryotes, single cell eukaryotes, lower multicellular eukaryotes, and mammals, examining how epigenetic factors contribute to genome stability and how these species pass memories of encounters to progeny. Topics also include major DNA repair mechanisms, the role of chromatin in genome stability, human diseases associated with genome instability, and genome stability in response to aging. This second edition has been fully revised to address evolving research trends, including CRISPRs/Cas9 genome editing; conventional versus transgenic genome instability; breeding and genetic diseases associated with abnormal DNA repair; RNA and extrachromosomal DNA; cloning, stem cells, and embryo development; programmed genome instability; and conserved and divergent features of repair. This volume is an essential resource for geneticists, epigeneticists, and molecular biologists who are looking to gain a deeper understanding of this rapidly expanding field, and can also be of great use to advanced students who are looking to gain additional expertise in genome stability. A deep analysis of genome stability research from various kingdoms, including epigenetics and transgenerational effects Provides comprehensive coverage of mechanisms utilized by different organisms to maintain genomic stability Contains applications of genome instability research and outcomes for human disease Features all-new chapters on evolving areas of genome stability research, including CRISPRs/Cas9 genome editing, RNA and extrachromosomal DNA, programmed genome instability, and conserved and divergent features of repair

Telomerase, an enzyme that maintains telomeres and endows eukaryotic cells with immortality, was first discovered in tetrahymena in 1985. In 1990s, it was proven that this enzyme also plays a key role in the infinite proliferation of human cancer cells. Now telomere and telomerase are widely accepted as important factors involved in cancer biology, and as promising diagnostic tools and therapeutic targets. Recently, role of telomerase in “cancer stem cells” has become another attractive story. Until now, there are several good books on telomere and telomerase focusing on biology in ciliates, yeasts, and mouse or basic sciences in human, providing basic scientists or students with updated knowledge.

This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.

Splicing of primary RNA transcript is a quasi-systematic step of gene expression in higher organisms. This is the first book to highlight the medical implications, i.e. diseases, caused by alternative splicing. Alternative splicing not only vastly increases protein diversity but also offers numerous opportunities for aberrant splicing events with pathological consequences. The book also outlines possible targets for therapy.
