    Noncoding Way of the Metastasis
    (Elsevier, 2022) Göker Bağca, Bakiye; Kuşoğlu, Alican; Çeşmeli, Selin; Biray Avcı, Çığır
    According to the World Health Organization statistics, the second leading cause of death globally is cancer. Together with this, metastasis is viewed as the leading cause of cancer death in patients with the disease due to the lack of treatment modalities for malignant tumors. One of the key mechanisms related to cancer metastasis is the epithelial-mesenchymal transition which enables epithelial cancer cells to gain mesenchymal cancer cell properties with elevated migration and invasion capacity that make it easy to spread distant tissues and survive from harsh conditions. Studies indicate that metastatic cancer cells have a gene expression signature that ensures those cells have increased migratory capacity as well as increased survival rate in circulation. Recently, the relationship of metastasis with two types of noncoding RNAs (ncRNAs), microRNAs (miRNAs), and long noncoding RNAs (lncRNAs) has been getting attention. In this chapter, the role of miRNAs and lncRNAs and treatment strategies regarding the role of ncRNAs in metastasis biology will be evaluated.

    Endogenous miRNA Sponges
    (Humana Press, 2022) Alkan, Ayşe Hale; Akgül, Bünyamin
    MicroRNAs (miRNAs) are a class of noncoding RNAs of 17–22 nucleotides in length with a critical function in posttranscriptional gene regulation. These master regulators are themselves subject to regulation both transcriptionally and posttranscriptionally. Recently, miRNA function has been shown to be modulated by exogenous RNA molecules that function as miRNA sponges. Interestingly, endogenous transcripts such as transcribed pseudogenes, long noncoding RNAs (lncRNAs), circular RNAs (circRNAs) and mRNAs may serve as natural miRNA sponges. These transcripts, which bind to miRNAs and competitively sequester them away from their targets, are naturally existing endogenous miRNA sponges, called competing endogenous RNAs (ceRNAs). Here we present a historical background of miRNAs, exogenous and endogenous miRNA sponges as well as some examples of endogenous miRNA sponges involved in regulatory mechanisms associated with various diseases, developmental stages, and other cellular processes. © 2022, Springer Science+Business Media, LLC, part of Springer Nature.
