Cardiac hypertrophy is an ongoing clinical challenge, as risk factors such as obesity, smoking and increasing age become more widespread, which lead to an increasing prevalence of developing hypertrophy. Pathological hypertrophy is a maladaptive response to stress conditions, such as pressure overload, and involve a number of changes in cellular mechanisms, gene expression and pathway regulations. Although several important pathways involved in the remodeling and hypertrophy process have been identified, further research is needed to achieve a better understanding and explore new and better treatment options. More recently discovered pathways showed the involvement of several non-coding RNAs, including micro RNAs (miRNAs), long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs), which either promote or inhibit the remodeling process and pose a possible target for novel therapy approaches. modeling serves as a vital tool for this further pathway analysis and treatment testing and has vastly improved over the recent years, providing a less costly and labor-intensive alternative to animal models.
心脏肥大是一个持续存在的临床挑战,随着肥胖、吸烟和年龄增长等危险因素日益普遍,导致心脏肥大的患病率不断上升。病理性肥大是对压力过载等应激条件的一种适应性不良反应,涉及细胞机制、基因表达和信号通路调控等多个方面的变化。尽管已经确定了一些参与重塑和肥大过程的重要信号通路,但仍需要进一步研究以更好地理解并探索新的、更好的治疗方案。最近发现的信号通路显示,包括微小RNA(miRNA)、长链非编码RNA(lncRNA)和环状RNA(circRNA)在内的几种非编码RNA参与其中,它们要么促进要么抑制重塑过程,为新型治疗方法提供了可能的靶点。建模是进一步进行信号通路分析和治疗测试的重要工具,并且近年来有了很大改进,为动物模型提供了一种成本更低、劳动强度更小的替代方案。
