Circular RNAs (circRNAs) are non-coding RNA (ncRNA) molecules that, due to their covalent ring structure and lack of free ends, have a very high intracellular stability compared linear counterparts. In general, circRNAs expressed in mammalian cells exhibit tissue/cell-specific expression patterns. Mounting evidence is indicative that regulate variety cellular processes by acting as miRNA sponges, transcriptional regulators, protein molecular scaffolds, protein/peptide translators. The emergence the biological functions has brought novel outlook our better understanding physiology disease pathogenesis. CircRNAs also been shown play critical role occurrence, development progression cancers. Their participation pathophysiology various diseases including cardiovascular diseases, diabetes neurological disorders important. Such characteristics led more studies investigating promising tools medicine targeted therapy.

Abstract Micropeptides are commonly identified as peptides encoded by non‐coding RNAs (ncRNAs). In the short open reading frame (sORF) of ncRNAs, there is a base sequence encoding functional micropeptides, which great significance in biological field. Recently, micropeptides regulate diverse processes, including mitochondrial metabolism, calcium transport, mRNA splicing, signal transduction, myocyte fusion, and cellular senescence, regulating homeostasis internal environment cancer's incidence progression. Especially, study cancer about potential regulatory mechanism will be conducive to further understanding process initiation development. More more research shows have been confirmed play an essential role emergence multiple kinds cancers, Breast cancer, Colon Colorectal Glioma, Glioblastoma, Liver cancer. This review presents comprehensive synthesis latest advancements our roles cells, with particular focus on networks involving oncogenesis. The new mode action provides innovative ideas for diagnosis treatment. Moreover, we explored significant capacity diagnostic biomarkers targets anti‐cancer therapies clinical settings, highlighting their development micropeptide‐based tools therapeutics.

Abstract Developing messenger RNA (mRNA) vaccines for COVID-19 renewed and intensified the interest in using mRNA disease prevention treatment. Despite their efficacy, linear molecules are short-lived human body, primarily due to enzymatic degradation at free ends. In contrast, circular (circRNA) exhibits enhanced stability resistance exonuclease degradation. However, this depends highly on purity. Unfortunately, vitro transcription/self-splicing reaction products contain a mixture of RNAs. Yet, practical methods purifying circRNA from solutions containing contaminants lacking. study, we explored feasibility ultrafiltration purify protein-encoding produced by self-splicing precursor (preRNA) during transcription (IVT). We measured sieving coefficients, separation metric, circRNA, RNA, nicked conformers polyethersulfone membranes with molecular weight cutoffs 30 300 kDa, analyzing performance as function permeate flux. also estimated critical fluxes determined suitable operating conditions purification. achieved purity 86% yield above 50%. By comparison, size-exclusion high-performance liquid chromatography (SE-HPLC), leading alterative technology, was 41% 45%. These findings highlight superior method research scale. Its scalability suggests that it could play role enabling large-scale manufacturing circRNA-based therapeutics.
