Elevated pressure upregulated the expression of Caspase‑1, GSDMD‑N, IL‑18 and IL‑1β in IR‑treated or OGD‑treated microglia both in vivo and in vitro. More importantly, Caspase‑1, GSDMD‑N, IL‑18 and IL‑1β expression in microglia was significantly downregulated when elevated pressure was reduced or removed. These results suggested that elevated ICP‑induced IL‑1β and IL‑18 overproduction via activation of the NLRP3 inflammasome by ischemia‑activated microglia may augment neuroinflammation.Cisplatin (DDP) resistance is a major obstacle in the chemotherapeutic efficacy of ovarian cancer. The present study aimed to explore the role of miR‑576‑3p in DDP sensitivity of ovarian cancer cells. Ovarian cancer cell lines SKOV3 and A2780 and DDP‑resistant ovarian cancer cell lines SKOV3/DDP and A2780/DDP were used in the present study. In vitro studies demonstrated that microRNA (miR)‑576‑3p overexpression increased the DDP sensitivity of DDP‑resistant ovarian cancer cells. A dual‑luciferase assay verified that both programmed death‑ligand 1 (PD‑L1) and cyclin D1 were targets of miR‑276‑3p and were reversely associated with the expression of miR‑576‑3p. Moreover, in vivo studies indicated that tumorigenesis was inhibited by DDP, which was enhanced by further miR‑576‑3p overexpression in tumor tissues. Taken together, the results suggested that miR‑576‑3p overexpression increased DDP chemosensitivity of ovarian cancer cells via decreasing PD‑L1 and cyclin D1, indicating that miR‑576‑3p may serve as a promising therapeutic target for ovarian cancer.Subsequently to the publication of the above article, the authors have realized that the bar charts shown for Fig. 3A and B, as they appeared in the paper, were the same as the bar charts shown for Fig. 4B and D. Fig. 3, as it should have appeared, is shown below. All the authors agree to this Corrigendum. Note that the revisions made to this figure do not adversely affect the results reported in the paper, or the conclusions stated therein. The authors regret that the duplication of the histograms in Fig. 4 as Fig. 3 was not noticed prior to the publication of this article, and offer their apologies to the Editor of Molecular Medicine Reports and to the readers of the Journal.

However, the mechanism underlying sepsis‑induced endothelial cell injury remains unclear. The present study hypothesized that sepsis‑induced inflammatory injury of endothelial cells may be the first step of endothelial barrier dysfunction. C381 chemical structure Therefore, the present study aimed to uncover the mechanism underlying the inflammatory effects of sepsis. A rat model of cecal ligation and puncture‑induced sepsis was established, and septic serum was collected. Subsequently, human umbilical vein endothelial cells (HUVECs) were treated with the isolated septic or normal serum. HUVEC viability was assessed using a Cell Count Kit‑8 assay. Furthermore, transmission electron microscopy and reverse transcription‑quantitative PCR (RT‑qPCR) analysis were carried out to observe the cell morphology and determine the mRNA expression levels in septic serum‑induced HUVECs. The protein expression levels were evaluated by western blot ana‑acetylcysteine, the ERK1/2 inhibitor PD98059, the p38 inhibitor SB203580, the JNK inhibitor SP610025 or the NF‑κB inhibitor pyrrolidine dithiocarbamate restored the septic serum‑induced IL‑1β, IL‑6 and TNF‑α expression. In conclusion, the results of the current study suggested that the septic serum‑induced endothelial cell injury may be mediated by increasing ROS generation, activation of mitogen‑activated protein kinases and NF‑κB translocation.Transforming growth factor β1 (TGF‑β1) is one of the most important fibrogenic factors promoting the activation of hepatic stellate cells (HSCs). Autophagy is a process used by cells to degrade and recycle cellular proteins. Although TGF‑β1 induces autophagy in several other cellular systems, the association between its effect on fibrogenesis and autophagy in HSCs have not been determined. Liver tissues from C57BL/6 mice and the mouse HSC line JS1 were analyzed. Acute and chronic liver injury models were induced by carbon tetrachloride (CCl4), and JS1 cells were stimulated by TGF‑β1 to assess the mechanism and relationship between autophagy and fibrosis. Liver tissues from acute and chronic injury models induced by CCl4 demonstrated evidence of increased autophagic activity, as assessed by the expression of the microtubule‑associated protein 1 light chain 3BII protein. TGF‑β1 stimulated the activation of JS1 cells and simultaneously increased autophagy flux. However, this effect was attenuated when autophagy was inhibited using chloroquine, 3‑methyladenine or lentiviral short hairpin RNA‑mediated knockdown of autophagy‑related gene 7. Furthermore, whether MAPK, including ERK, JNK and p38 MAPK cascades were associated with TGF‑β1‑induced autophagy in JS1 cells was determined. Subsequently, it was shown that the ERK inhibitor, PD98059, and JNK inhibitor, SP600125, were able to reverse TGF‑β1‑induced autophagy and fibrosis. The results of the present study suggest that TGF‑β1‑induced autophagy is involved in the activation of JS1 cells, possibly through activation of the ERK and JNK signaling pathways.Preeclampsia (PE) is a pregnancy‑specific complication characterized by hypertension and proteinuria, and it is one of the primary global causes of maternal and perinatal mortality. Poor remodeling of placental arteries and endothelial dysfunction serve important roles in the pathogenesis of PE. Peptide derived from complement C4 A chain (PDCC4) was identified in our previous peptidome analysis of serum from patients with PE. The present study aimed to investigate the effect of PDCC4 on endothelial dysfunction in PE. TNF‑α stimulated HUVECs were employed to mimic endothelial dysfunction in PE, and Cell Counting Kit 8 assay, wound healing assay, tube formation assay, RNA‑sequencing (seq) and western blot analysis were performed using HUVECs. Moreover, an in vivo model of PE was established using pregnant rats treated with lipopolysaccharide (LPS), and blood pressure monitoring, histopathological examination, ELISA and immunohistochemistry were performed on rats. It was found that TNF‑α impaired proliferation, migration and tube formation of HUVECs, but pretreatment with PDCC4 moderated these effects.
