Conference Object A Carbohydrate sulfotransferase mutant zebrafish shows importance of keratan sulfate proteoglycan in skeletal structure(Mary Ann Liebert, 2024) Basol, M.; Ersoz, E.; Özaktaş, Helin; Cakan-Akdogan, G.Review Citation - WoS: 9Citation - Scopus: 7Micrornas and Long Non-Coding Rnas as Novel Targets in Anti-Cancer Drug Development(Bentham Science Publishers, 2023) Çetinkaya, Melisa; Baran, YusufNon-coding RNAs comprise the majority of RNAs that have been transcribed from the human genome, and these non-coding RNAs have essential regulatory roles in the cellular processes. They have been discovered to influence the expression of the genes, including tumor-suppressive and oncogenes, that establish the non-coding RNAs as novel targets for anti-cancer drug development. Among non-coding RNAs, microRNAs have been extensively studied in terms of cancer biology, and some microRNA-based therapeutics have been reached in clinical studies. Even though most of the research regarding targeting non-coding RNAs for anti-cancer drug development focused on microRNAs, long non-coding RNAs have also started to gain importance as potential therapeutic targets for cancer therapy. In this chapter, the strategies and importance of targeting microRNAs and long non-coding RNAs will be described, along with the clinical studies that involve microRNA-based cancer therapeutics and preclinical studies that involve long non-coding RNA-based therapeutics. Finally, the delivery strategies that have great importance in the effective delivery of the non-coding RNA-based cancer therapeutics, hence the therapy's effectiveness, will be described.Book Part Citation - Scopus: 5Epitranscriptomics Changes the Play: M6a Rna Modifications in Apoptosis(Springer, 2022) Akçaöz, Azime; Akgül, BünyaminApoptosis is a form of programmed cell death that is essential for cellular and organismal homeostasis. Any irregularities that disturb the balance between apoptosis and cell survival have severe implications, such as improper development or life-threatening diseases. Thus, it is highly critical to maintain a proper rate of apoptosis throughout development. In fact, several complex transcriptional and posttranscriptional mechanisms exist in eukaryotes to critically regulate the rate of apoptotic processes. Recent studies suggest that not only RNA sequences but also their modifications, such as m6A methylation, play a fundamental role in these transcriptional and posttranscriptional processes. A specific set of proteins, called writer, eraser, and reader of m6A marks, modulate the rate of apoptosis by determining the m6A repertoire and the fate of certain transcripts associated with apoptosis. In this Review, we will cover the dynamic m6A RNA modifications and their impact on modulation of apoptosis.Article Citation - WoS: 3Citation - Scopus: 4Applicability of Low-Intensity Vibrations as a Regulatory Factor on Stem and Progenitor Cell Populations(Bentham Science Publishers, 2020) Baskan, Öznur; Karadaş, Özge; Meşe, Gülistan; Özçivici, EnginPersistent and transient mechanical loads can act as biological signals on all levels of an organism. It is therefore not surprising that most cell types can sense and respond to mechanical loads, similar to their interaction with biochemical and electrical signals. The presence or absence of mechanical forces can be an important determinant of form, function and health of many tissue types. Along with naturally occurring mechanical loads, it is possible to manipulate and apply external physical loads on tissues in biomedical sciences, either for prevention or treatment of catabolism related to many factors, including aging, paralysis, sedentary lifestyles and spaceflight. Mechanical loads consist of many components in their applied signal form such as magnitude, frequency, duration and intervals. Even though high magnitude mechanical loads with low frequencies (e.g. running or weight lifting) induce anabolism in musculoskeletal tissues, their applicability as anabolic agents is limited because of the required compliance and physical health of the target population. On the other hand, it is possible to use low magnitude and high frequency (e.g. in a vibratory form) mechanical loads for anabolism as well. Cells, including stem cells of the musculoskeletal tissue, are sensitive to high frequency, low-intensity mechanical signals. This sensitivity can be utilized not only for the targeted treatment of tissues, but also for stem cell expansion, differentiation and biomaterial interaction in tissue engineering applications. In this review, we reported recent advances in the application of low-intensity vibrations on stem and progenitor cell populations. Modulation of cellular behavior with low-intensity vibrations as an alternative or complementary factor to biochemical and scaffold induced signals may represent an increase of capabilities in studies related to tissue engineering.
