The mitochondrial electron transport chain (ETC) plays an essential role in energy production by inducing oxidative phosphorylation (OXPHOS) to drive numerous biochemical processes eukaryotic cells. Disorders of ETC and OXPHOS systems are associated with mitochondria- metabolism-related diseases, including cancers; thus, a comprehensive understanding the regulatory mechanisms is required. Recent studies have indicated that noncoding RNAs (ncRNAs) play key roles functions; particular, some ncRNAs been shown modulate systems. In this review, we introduce emerging ncRNAs, microRNAs (miRNAs), transfer-RNA-derived fragments (tRFs), long (lncRNAs), circular (circRNAs), regulation.

Abstract Current treatment strategies for cancer, especially advanced are limited and unsatisfactory. One of the most substantial advances in cancer therapy, last decades, was discovery a new layer immunotherapy approach, immune checkpoint inhibitors (ICIs), which can specifically activate cells by targeting checkpoints. Immune checkpoints type immunosuppressive molecules expressed on cells, regulate degree activation avoid autoimmune responses. ICIs, such as anti-PD-1/PD-L1 drugs, has shown inspiring efficacy broad applicability across various cancers. Unfortunately, not all patients benefit remarkably from overall response rates to ICIs remain relatively low types. Moreover, primary acquired resistance pose serious challenges clinical application immunotherapy. Thus, deeper understanding molecular biological properties regulatory mechanisms is urgently needed improve options fo r current therapies. Recently, circular RNAs (circRNAs) have attracted increasing attention, only due their involvement aspects hallmarks, but also impact shaping tumor microenvironment. In this review, we systematically summarize status existing roles circRNAs Meanwhile, aim settle issue an evidence-oriented manner that involved hallmarks effects

Abstract Circular RNAs (circRNAs) are a class of covalently closed, endogenous ncRNAs. Most circRNAs derived from exonic or intronic sequences by precursor RNA back-splicing. Advanced high-throughput sequencing and experimental technologies have enabled the extensive identification characterization circRNAs, such as novel types biogenesis, tissue-specific cell-specific expression patterns, epigenetic regulation, translation potential, localization metabolism. Increasing evidence has revealed that participate in diverse cellular processes, their dysregulation is involved pathogenesis various diseases, particularly cancer. In this review, we systematically discuss databases, challenges for circRNA discovery, new insight into strategies used studies biomedical applications. Although recent advanced understanding knowledge approaches annotation, functional applications continuously needed to provide insights circRNAs. The emergence circRNA-based protein strategy will be promising direction field biomedicine.

Abstract The carcinogenic role of FASN by regulating lipid metabolism reprogramming has been well-established in multiple tumors. However, whether mechanisms during intrahepatic cholangiocarcinoma (ICC) progression, such as circRNAs, regulate expression remains unknown. Here we demonstrate a metabolism-related circRNA, circMBOAT2 (hsa_circ_0007334 circBase), frequently upregulated ICC tissues, and positively correlated with malignant features. CircMBOAT2 knockdown inhibits the growth metastasis cells. Mechanistically, combines PTBP1 protects from ubiquitin/proteasome-dependent degradation, impairing function to transfer mRNA nucleus cytoplasm. Moreover, have same effect on fatty acid profile, unsaturated acids instead saturated are primarily regulated associated behaviors levels peroxidation ROS were significantly higher when was knocked down recovered overexpressed. Our results identified that promoted progression stabilizing facilitate cytoplasmic export, which altered metabolic profile redox homeostasis ICC, suggesting may serve an available therapeutic target for active metabolism.
