Methods The human monocytic U937 cells were treated with S. aureus at different time with or without SP600125. Cell apoptosis was analyzed by flow cytometry. JNK, Bax, and caspase-3 activities were detected by Western blotting. Results S. aureus induced apoptosis in cultured U937 cells in a time-dependent manner. Expression of Bax and phospho-JNK significantly increased in S. aureus-treated U937 cells, and the level of activated caspase-3 also increased in a time-dependent manner. Inhibition of JNK with SP600125 significantly inhibited S. aureus-induced apoptosis in U937 cells. Conclusions S. aureus can induce apoptosis in U937 cells by phosphorylation of JNK and activation of Bax and caspase-3. SP600125 protects U937 cells from apoptosis induced by S. aureus via inhibiting the activity of JNK.展开更多

Methods:A total of 70 SPF-grade healthy adult female Wistar rats were selected, and were randomly divided into 5 groups using a random number table: model group, positive group, curcumin group, PDT group, and PDT+curcumin group. The rat model of cervical cancer was constructed by intraperitoneal injection of U14 cells(5 ×106/mL) 1mL. After successful modeling, the model group was given intraperitoneal injection of normal saline+natural light, and the positive group was intraperitoneally injected with 100 mg/kg DAPT solution+Natural light, the curcumin group was given intraperitoneal injection of 200 μL of 150 μmol/L curcumin+natural light, the PDT group was given intraperitoneal injection of normal saline+photodynamic therapy at 100 J/cm^(2), and the PDT+curcumin group was given intraperitoneal injection of 200 μL of 150 μmol/L curcumin+photodynamic therapy at 100 J/cm^(2). Results: HE staining results showed that PDT+ curcumin group exhibited a more sparse arrangement of tumor cells in the lesion tissue slices, relatively smaller cell volume, lower nuclear-cytoplasmic ratio, and more condensed nuclei, with a noticeable presence of vesicular nuclei and perinuclear halos than the other four groups. The expression of Notch-1 protein in PDT+curcumin group, as measured by immunohistochemistry and Western blotting, was significantly lower than that in other four groups(P<0.05). CD4^(+), CD8^(+)and CD4^(+)/CD8^(+)expression levels in PDT+curcumin group were higher than those in model group, positive group and PDT group(P<0.05). The expression of Bcl-2 protein in PDT+curcumin group was lower than that in the other four groups, and the expression of Bax protein in PDT+curcumin group was higher than that in the other four groups(P<0.05). Conclusion: Curcumin-mediated PDT can inhibit Notch signaling pathway, promote immune factors, and regulate the expression of apoptosis-related proteins such as Bcl-2 and Bax.展开更多

Cell apoptosis in liver tissues was assessed via terminal deoxynucleotidyl transferase d UTP nick-end labelling assay. In addition, the m RNA and protein expression levels of p-JNK,p-c-Jun, caspase-8, Fas, and Fas-L were determined via fluorescence-based quantitative real-time PCR,immunohistochemical and Western blot assays.RESULTS: Histopathological examination of the liver showed that the model rats had moderate-to-severe steatosis with infiltration of inflammatory cells as well as significantly higher expression levels of the p-JNK, p-c-Jun, caspase-8, Fas, and Fas-L proteins, compared with those in the blank control group(P < 0.01). Hepatic lobules of the rats in the treatment groups showed significantly reduced vacuolar degeneration and steatosis as well as alleviated inflammatory cell infiltration. The high and medium-dose CGXZ groups exhibited significantly lower m RNA and protein expression levels of p-JNK, p-c-Jun, caspase-8, Fas, and Fas-L, compared with those in the model group(P < 0.05 or P <0.01).CONCLUSION: CGXZ pill inhibited the onset of hepatocyte apoptosis by regulating the expression of p-JNK, p-c-Jun, caspase-8, Fas, and Fas-L, thereby exerting therapeutic effects against NASH.展开更多
