The recent advantage obtained by next generation sequencing allows a depth investigation of a new "old" kind of noncoding transcript, the circular RNAs. Circular RNAs are nontranslated RNAs, typically nonpolyadenylated, with a resistance to exonucleases that gives them the ability to be more stable than the common linear RNA isoforms. We used a bioinformatic detection tool (CIRCexplorer) to research predictive circRNAs from the next generation sequenced data of five samples of ductal in situ carcinoma (DCIS) and matched adjacent invasive ductal carcinoma (IDC). Furthermore, we also investigated the circular RNAs expressed in MCF7, an invasive breast ductal carcinoma cell line. We described the genomic context of the predicted circular RNAs and we address the hypothetical possible functional roles. This study showed a perspective of a panel of predictive circRNAs identified and the function that circRNAs could exert.

The genomic-level characteristics play a pivotal role as genetic assets for the identification of species and phylogenetic analysis. Here, we sequenced and analyzed the mitochondrial genome of (Ratzeburg), which was first morphologically described in "Die Ichneumonen der Forstinsecten in forstlicher und entomologischer Beziehung." The motivation for this research arises from the necessity to comprehend the genetic composition and evolutionary history of , a genus of parasitic wasps with potential agricultural significance, which.

Background: Colorectal cancer (CRC) remains one of the most common causes of cancer-related mortality worldwide. Its progression is influenced by complex interactions involving genetic, epigenetic, and environmental factors. Non-coding RNAs (ncRNAs), including microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs), have been identified as key regulators of gene expression, affecting diverse biological processes, notably programmed cell death (PCD).

Background: Head and neck squamous cell carcinoma (HNSCC), a highly invasive malignancy with a poor prognosis, is one of the most common cancers globally. Circular RNAs (circRNAs) have become key regulators of human malignancies, but further studies are necessary to fully understand their functions and possible causes in HNSCC.
Methods: CircCCT2 expression levels in HNSCC tissues and cells were measured via qPCR.

Background: Muscle and adipose tissue are the most critical indicators of beef quality, and their development and function are regulated by noncoding RNAs (ncRNAs). However, the differential regulatory mechanisms of ncRNAs in muscle and adipose tissue remain unclear.
Results: In this study, 2,343 differentially expressed mRNAs (DEMs), 235 differentially expressed lncRNAs (DELs), 95 differentially expressed circRNAs (DECs) and 54 differentially expressed miRNAs (DEmiRs) were identified in longissimus dorsi muscle (LD), subcutaneous fat (SF) and perirenal fat (VF) in Qinchuan beef cattle.

Chemotherapy and radiotherapy (chemo-/radiotherapy) have advanced as the main treatment modalities for nasopharyngeal carcinoma (NPC), improving patient survival rates. However, chemo-/radiotherapy resistance in NPC cells has emerged as a key factor contributing to poor prognosis. Recently, competing endogenous RNA networks (ceRNETs) have garnered attention for their potential clinical value in studying chemo-/radiotherapy resistance.
