Recently, with the development of RNA research techniques, a wide variety of circular RNAs (circRNAs) have been discovered and some of them are confirmed to have crucial biological functions. CircRNAs arise from exons (i.e. exonic circRNAs) or introns (i.e. intronic circRNAs). Acting as microRNA sponges or combining with proteins, circRNAs participate in the regulation of gene expression and influence the activity of some proteins. In addition, some circRNAs even encode proteins. More importantly, several circRNAs play a key role in the occurrence and progression of some tumors, including stomach, liver, colon, breast, cervical, and ovarian cancers. Therefore, circRNAs may be a novel type of diagnostic marker and therapeutic target of cancers.

Hepatocellular carcinoma (HCC) is one of the common malignant tumors. HCC gene regulatory network (HCC GRN), whose nodes consist of genes, miRNAs or TFs and whose edges consist of interaction relationships of nodes, is one of the important ways to study molecular mechanism of HCC. Based on various experimental data, types of HCC GRNs could be conducted such as TF-miRNA regulatory network. Integrating the studies of HCC GRN, TF-miRNA transcriptional regulatory network performs better in identifying core genes which play important roles in network disturbances. It is a trend that gene variations and transcriptional regulatory networks should be combined, however the corresponding research is almost blank. This review summarizes the source of HCC data sources, the classification, character, and research program of HCC GRN. Finally, according to present analysis and discussion of progress and research status of HCC GRN, we provide a useful reference for researchers.

This paper was aimed to investigate the microRNA associated with multidrug resistance gene MDR1 of salvianolic acid A reversal in lung cance. Human lung cancer A549 cells were divided into normal control group and drug group, and the MDR1 expression levels were determined by real-time quantitative PCR. MicroRNA expression profiling of normal control group and drug group were detected by using the latest microRNA microarray. Quantitative RT-PCR was used to validate the differentially expressed miRNA. Forecast of miRNA associated with MDR1 multi-resistant genes of up-regulated miRNA. Experimental results showed that the dosage of MDR1 expression level significantly lowered compared with control group. The miRNA expression spectrum analyses of human lung cancer A549 cells to drug group and the control group were detected by microRNA microarray, 426 differentially expressed miRNA were screened out. Then target prediction were performed for difference up-expression of miRNA and found that there were four obvious increase of miRNA associated with MDR1 multi-resistant genes. Real-time quantitative PCR for 4 microRNA verification, the results were consistent with the chip. So the author considered that salvianolic acid A down lung cancer multidrug resistance gene MDR1 is likely to be affected by the miRNA expression and regulation of target genes, to further clarify the traditional Chinese medicine to reverse multi-drug resistant mechanism provides the experimental basis.

Glucocorticoid receptor (GR) is identified as a member of nuclear receptor family. To exert its biological action, the ligand bound GR is translocated from the cytoplasm into the nucleus by regulating transcriptional signals of related genes. In clinical practice, the effects of glucocorticoid are often mediated by GR signaling pathways. An increasing number of studies have indicated that GR signaling pathways play an essential role in the proliferation, invasion and prognosis of bladder cancer. Meanwhile, the new-generation selective GR activator improves its anti-tumor effects, and at the same time reduces the adverse reactions of hormones, which probably raises the prospect for the treatment of bladder cancer.

Objective: To investigate the TNFAIP3/A20 abnormalities and its association with Epstein-Barr virus (EBV) in classical Hodgkin lymphoma (CHL). Methods: Formalin-fixed, paraffinembedded tissue blocks of 54 CHL patients were collected and subjected to the construction of tissue microarray (TMA) for further analyses. EBV status was evaluated by in situ hybridization (ISH) for EBER1/2 and immunohistochemistry (IHC) with anti-LMP-1 antibody. Fluorescence in situ hybridization (FISH) and IHC were performed to determine the copy number alterations of TNFAIP3 and A20 protein expression respectively. Results: The concordance rate of IHC for LMP-1 and ISH for EBER1/2 was100%, and 25.9% (14/54) cases were identified with EBV infection. Immunohistochemistry analysis demonstrated 27.8% (15/54) cases with A20 expression deficiency. Of the 54 cases tested for A20 expression, 49 cases were simultaneously analyzed by FISH, which showed 10 (20.4% ) cases harboring TNFAIP3 deletion. However, discrepancy was observed between the results of A20 by IHC and TNFAIP3 deletion by FISH. Only 1 case with TNFAIP3 deletion demonstrated complete loss of A20 immunoreactivity. In addition, comparison of the frequency of either A20 expression loss or TNFAIP3 deletion between EBV-positive and-negative cases did not reveal any significance (P>0.05). Conclusion: TNFAIP3 deletion could be observed in both EBV-positive and - negative CHL cases. A20 expression by IHC could not confirm TNFAIP3 deletion by FISH, which might be related to the technical issues.
