A large amount of non-coding RNA are found existing in eukaryotic transcriptome, which play an important role in regulating the expression of genes as well as participating in physiological and pathological process of various cells.In recent years,the research of ncRNA in diagnosis of breast cancer is extremely hot. In this review, the research of three types of peripheral blood ncRNAs as breast cancer diagnostic biomarkers were reviewed, including microRNA(miRNA), long non-coding RNA(lncRNA), and circular RNA(circRNA).Also,the prospect of ncRNA in clinical research and translational medicine of breast cancer was mentioned, in order to provide a new idea for breast cancer with the discovery of diagnostic markers in early detection and the monitoring of diagnosis and treatment process.

OBJECTIVE: To investigate the expression of ZNF652 in breast cancer tissues and cells and explore its role in breast cancer cell proliferation, invasion and migration. METHODS: We exploited the data from the TCGA database to analyze the differential expression of ZNF652 in breast cancer tissues and adjacent tissues and the correlations of ZNF652 expression with the clinicopathological characteristics of breast cancer patients including molecular subtypes, pathological types, TNM stages and clinical stages. RT-qPCR and Western blotting were used to detect the expression of ZNF652 in 5 breast cancer cell lines including MCF-7, MDA-MB-231, SK-BR-3, UACC-812 and BT-474. Using a lentivirus system and siRNA technique, we assessed the effects of ZNF652 over-expression and knockdown on proliferation, colony forming ability, migration and invasion of breast cancer cells with CCK-8 assay, clonogenic assay, Transwell assay and wound healing assay. The subcellular localization of ZNF652 in 293T cells was determined using immunofluorescence assay. RESULTS: ZNF652 was significantly up-regulated in breast cancer tissues ( CONCLUSIONS ZNF652 is highly expressed in breast cancer tissues and cells to promote the development and progression of breast cancer and may serve as a potential molecular target for diagnosis and treatment of the malignancy.

Since the outbreak of COVID-19 pandemic, the detection capability has been improving and the detection techniques have been evolving with innovations. qRT- PCR and mNGS, which represent the current mainstay diagnostic technologies, play key roles in disease diagnosis and monitoring of virus variation. The detection technologies based on serum and plasma IgM and IgG antibodies are important for auxiliary diagnosis. RT-LAMP is highly specific for a diagnostic purpose. Digital PCR could quantitatively detect nucleic acid and SHERLOCK has a higher sensitivity. These techniques all have great potential for future development and application for pathogen detection. In this review the authors summarize the basic rationales, technical characteristics and the current application of the SARS-CoV-2 detection techniques.
