Current Concepts of NonCoding RNAs in the Biology Diagrams Holdt, L. M. et al. Alu elements in ANRIL non-coding RNA at chromosome 9p21 modulate atherogenic cell functions through trans-regulation of gene networks. PLoS Genet. 9 , e1003588 (2013).
Circular RNAs (circRNAs), a type of non‐coding RNA, are single‐stranded circularized molecules characterized by high abundance, evolutionary conservation and cell development‐ and tissue‐specific expression. The functions and mechanisms of circRNAs in cell cycle regulation are largely focused on the G 1/ S phase transition and

These results indicate that lncRNAs that have cell-cycle-specific expression are candidates for regulation of cell-cycle progression and that they have distinct functions. There are a large number of these RNAs, each expressed at a specific time in the S-phase, which might facilitate the maintenance of gene expression programs in human cells. LncRNAs also participate in regulating alternative splicing, cell differentiation, and cell cycle regulation, and they are involved in regulating the occurrence of many diseases [12,13,14,15]. Dykes I.M., Emanueli C. Transcriptional and post-transcriptional gene regulation by long non-coding RNA. Genom. Proteom. circRNAs are single-stranded, highly stable, covalently closed RNA molecules that regulate gene expression either by acting as miRNAs sponges or by affecting mRNA and protein stability. 105 Many genes specific to the cell cycle are post-transcriptionally regulated by circRNAs, and disruption of this regulation can lead to cancer by accelerating
The mammalian cell cycle is precisely controlled by cyclin-dependent kinases (CDKs) and related pathways such as the RB and p53 pathways. Recent research on long non-coding RNAs (lncRNAs) indicates that many lncRNAs are involved in the regulation of critical cell cycle regulators such as the cyclins, CDKs, CDK inhibitors, pRB, and p53.
The crosstalk between non Biology Diagrams
Gene regulation by long non-coding RNAs and its biological functions there have been ~50,000 publications with 'long non-coding RNA' as a key term and more than 2,000 cell cycle and Cyclins and CDKs are key players in cell cycle regulation (Fig. 1). NcRNA CCND1, also called pncRNA (promoter-associated non-coding RNA), is transcribed from the upstream region of the cyclin D1 gene, CCND1, and negatively regulates cyclin D1. NcRNA CCND1 functions as a transcription factor regulator .
