05). Myocardial protein and mRNA expression of NOX2 and NOX4 was significantly downregulated in DOX+Val group compared with in the DOX group (all P less then 0.05). In vitro, ROS production and apoptosis in DOX‑treated H9C2 cells was significantly reduced by NOX2‑small interfering (si)RNA and NOX4‑siRNA, and significantly increased by overexpressing NOX2 and NOX4. To conclude, Val applied simultaneously with DOX could prevent DOX‑induced myocardial injury and reduce oxidative stress by downregulating the myocardial expression of NOX2 and NOX4 in rats.Age‑related cataract (ARC) is the leading cause of blindness worldwide. Oxidative DNA damage is a biochemical feature of ARC pathogenesis. The present study investigated the role of long non‑coding RNAs in the DNA repair of oxidative damage, partially the regulation of the DNA repair gene, 8‑oxoguanine DNA glycosylase (OGG1), in lens affected by ARC. The ogg1 mutant zebrafish model was constructed to verify the role of ogg1 in the lens. A high‑throughput lncRNA profiling was performed on human lens epithelial cells (LECs) following oxidative stress. The lncRNAs with the OGG1 target gene were analyzed for possible differentiated expression levels. The lens capsule samples of patients with ARC were collected to further verify the screening results. lncRNA was then overexpressed and knocked down in LECs to observe cell proliferation and apoptosis. The association between lncRNA, miRNA and the OGG1 mRNA 3'UTR were analyzed. The ogg1 mutant zebrafish developed more severe lens lesions following oxidative challenge. lncRNA NONHSAT143692.2 was distinctly expressed in various disease models. The knockdown of NONHSAT143692.2 downregulated the expression of OGG1 mRNA (P less then 0.001) and OGG1 protein (P less then 0.001), aggravated oxidative damage to LECs, increased apoptosis (P less then 0.001) and decreased cell proliferation (P less then 0.01). The overexpression of NONHSAT143692.2 reversed the above‑mentioned outcomes. miR‑4728‑5p was predicted to bind to NONHSAT143692.2 and OGG1 mRNA 3'UTR. The overexpression of miR‑4728‑5p downregulated the expression of NONHSAT143692.2 (P less then 0.001), OGG1 mRNA (P less then 0.001) and OGG1 protein (P less then 0.001). The knockdown of miR‑4728‑5p reversed the above‑mentioned outcomes. check details Overall, the findings of the present study demonstrate that the NONHSAT143692.2/miR‑4728‑5p/OGG1 axis may play an important role in the development of ARC. This novel concept may provide new insight into the molecular diagnosis and treatment of ARC.Axial spondyloarthritis (AxSpA) is a chronic rheumatic disease involving the axial skeleton. Recent evidence suggested that certain circular RNAs (circRNAs) have a crucial role in rheumatic diseases. However, the functions of circRNAs in AxSpA have remained largely elusive. The present study identified the utility of the circRNA Homo sapiens (hsa)_circ_0079787 as a potential biomarker for AxSpA. A total of 5 circRNAs (hsa_circ_0002715, hsa_circ_0001947, hsa_circ_0079787, hsa_circ_0000367 and hsa_circ_0035197) were determined in the peripheral blood of 46 patients with AxSpA, 46 patients with systemic lupus erythematosus (SLE) and 25 healthy controls (HC) by reverse transcription‑quantitative PCR analysis. The detailed clinical history of each patient was recorded and the correlations between these circRNAs and clinical characteristics were analyzed. Furthermore, receiver operating characteristic (ROC) curves were constructed to evaluate the diagnostic value of hsa_circ_0079787 and other factors for AxSpA. Of ombination of hsa_circ_0079787‑PLT‑MPV‑PCT may provide improved diagnostic accuracy for AxSpA. In addition, the levels of hsa_circ_0079787 in the peripheral blood were correlated with disease activity and severity of AxSpA.CD44 is widely expressed on the surface of most tissues and all hematopoietic cells, and regulates many genes associated with cell adhesion, migration, proliferation, differentiation, and survival. CD44 has also been studied as a therapeutic target in several cancers. Previously, an anti‑CD44 monoclonal antibody (mAb), C44Mab‑5 (IgG1, kappa) was established by immunizing mice with CD44‑overexpressing Chinese hamster ovary (CHO)-K1 cells. C44Mab‑5 recognized all CD44 isoforms, and showed high sensitivity for flow cytometry and immunohistochemical analysis in oral cancers. However, as the IgG1 subclass of C44Mab‑5 lacks antibody‑dependent cellular cytotoxicity (ADCC) and complement‑dependent cytotoxicity (CDC), the antitumor activity of C44Mab‑5 could not be determined. In the present study, we converted the mouse IgG1 subclass antibody C44Mab‑5 into an IgG2a subclass antibody, 5‑mG2a, and further produced a defucosylated version, 5‑mG2a‑f, using FUT8‑deficient ExpiCHO‑S (BINDS‑09) cells. check details Defucosylation of 5‑mG2a‑f was confirmed using fucose‑binding lectins, such as AAL and PhoSL. The dissociation constants (KD) for 5‑mG2a‑f against SAS and HSC‑2 oral cancer cells were determined through flow cytometry to be 2.8x10‑10 M and 2.6x10‑9 M, respectively, indicating that 5‑mG2a‑f possesses extremely high binding affinity. Furthermore, immunohistochemical staining using 5‑mG2a‑f specifically stained the membranes of oral cancer cells. In vitro analysis demonstrated that 5‑mG2a‑f showed moderate ADCC and CDC activities against SAS and HSC‑2 oral cancer cells. In vivo analysis revealed that 5‑mG2a‑f significantly reduced tumor development in SAS and HSC‑2 xenografts in comparison to control mouse IgG, even after injection seven days post‑tumor inoculation. Collectively, these results suggest that treatment with 5‑mG2a‑f may represent a useful therapy for patients with CD44‑expressing oral cancers.T‑2 toxin is a type A trichothecene mycotoxin. In order to reduce the side effects of T‑2 toxin and increase the tumor targeting ability, a pH‑sensitive liposome of T‑2 toxin (LP‑pHS‑T2) was prepared and characterized in the present study. The cytotoxicity of LP‑pHS‑T2 on A549, Hep‑G2, MKN‑45, K562 and L929 cell lines was tested by 3‑(4,5‑dimethylthiazolyl‑2)‑2,5‑diphenyltetrazolium bromide assay, with T‑2 toxin as the control. The apoptotic and migratory effects of LP‑pHS‑T2 on Hep‑G2 cells were investigated. The preparation process of LP‑pHS‑T2 involved the following parameters Dipalmitoyl phosphatidylcholine dioleoylphosphatidylethanolamine, 12; total phospholipid concentration, 20 mg/ml; phospholipidcholesterol, 31; 4‑(2‑hydroxyethyl)‑1‑piperazineethanesulfonic acid buffer (pH 7.4), 10 ml; druglipid ratio, 21; followed by ultrasound for 10 min and extrusion. The encapsulation efficiency reached 95±2.43%. The average particle size of LP‑pHS‑T2 after extrusion was 100 nm; transmission electron microscopy showed that the shape of LP‑pHS‑T2 was round or oval and of uniform size.
