The aim of this study was to verify the effects of circular RNA nuclear factor of activated T-cells, cytoplasmic 3 (circNFATC3), in oral squamous cell carcinoma (OSCC) development. The levels of circNFATC3, microRNA-520h (miR-520h), and lactate dehydrogenase A (LDHA) were measured by qRT-PCR and western blot analysis. The cellular functions were assessed by using commercial kits, MTT assay, EdU assay, flow cytometry analysis, and transwell assay. The interactions between miR-520h and circNFATC3 or LDHA were confirmed by dual-luciferase reporter assay. Finally, the mice test was enforced to evaluate the character of circNFATC3. We observed that the contents of circNFATC3 and LDHA were upregulated and miR-520h levels were downregulated in OSCC tissues compared with those in paracancerous tissues. For functional analysis, circNFATC3 knockdown repressed the cell glycolysis metabolism, cell proliferation, migration, and invasion, although it improved cell apoptosis in OSCC cells. LDHA could regulate the development of OSCC. circNFATC3 acted as a miR-520h sponge to modulate LDHA expression. In addition, the absence of circNFATC3 subdued tumor growth . In conclusion, circNFATC3 promoted the advancement of OSCC by adjusting the miR-520h/LDHA axis.

Objective: To determine the changes in the expression of circular RNA Circ-PALLD in heart failure and explore the biogenesis of Circ-PALLD.
Methods: We analyzed second-generation sequencing results of human and murine heart failure samples to identify the candidate CircRNAs. Sanger generation sequencing was performed after PCR amplification, and the sequencing results were compared to determine the reverse splicing pattern of the corresponding CircRNAs.

Background: Insulin like growth factor II mRNA binding protein 3 (IGF2BP3) is an RNA binding protein with multiple roles in regulation of gene expression at the post-transcriptional level and is implicated in tumorigenesis and progression of numerous cancers including gastric cancer (GC). Circular RNAs (circRNAs) are a diverse endogenous noncoding RNA population that have important regulatory roles in cancer. However, circRNAs that regulate the expression of IGF2BP3 in GC is largely unknown.

Article Synopsis
- Circular RNAs (circRNAs), particularly circNFATC3, play a significant role in the regulation of RAI14 and miR-23b-3p in gastric cancer, impacting patient prognosis.
- Higher levels of RAI14 and circNFATC3 or lower levels of miR-23b-3p are linked to worse outcomes for gastric cancer patients, suggesting a complex relationship between these molecules.
- The study demonstrates that restoring miR-23b-3p can inhibit cancer cell growth and invasion, while RAI14 promotes these processes, indicating potential therapeutic targets within the circNFATC3/miR-23b-3p/RAI14 regulatory axis.

Circular RNAs were once considered artifacts of transcriptome sequencing but have recently been identified as functionally relevant in different types of cancer. Although there is still no clear main function of circRNAs, several studies have revealed that circRNAs are expressed in various eukaryotic organisms in a regulated manner often independent of their parental linear isoforms demonstrating conservation across species. circNFATC3, an abundant and uncharacterized circular RNA of exon 2 and 3 from , was identified in transcriptomic data of solid tumors.
