Propofol attenuates TNF- α-induced MMP-9 expression in human cerebral microvascular endothelial cells by inhibiting Ca2+/CAMK II/ERK/NF-κB signaling pathway.
In conclusion, propofol inhibits TNF-α-induced MMP-9 expression in hCMEC/D3 cells via repressing the Ca2+/CAMKII/ERK/NF-κB signaling pathway. TNF-α-impaired BBB integrity could be reversed by propofol, and propofol attenuates the inhibitory effect of TNF-α on collagen IV. PMID: 31235816 [PubMed - as supplied by publisher]

Propofol Induces Cardioprotection Against Ischemia-Reperfusion Injury via Suppression of Transient Receptor Potential Vanilloid 4 Channel
Ca2+ entry via the transient receptor potential vanilloid 4 (TRPV4) channel contributes to Ca2+ overload and triggers many pathophysiological conditions, including myocardial ischemia/reperfusion (I/R) injury. Propofol, a widely used intravenous anesthetic, attenuates myocardial I/R injury. However, the mechanism of propofol remains to be examined. The present study aims to test the hypothesis that propofol attenuates myocardial I/R injury through the suppression of TRPV4. We used a murine ex vivo model of myocardial I/R and in vitro cultured myocytes subjected to hypoxia/reoxygenation (H/R). Propofol or TRPV4 antagonist, ...

Propofol Affects Non-Small-Cell Lung Cancer Cell Biology By Regulating the miR-21/PTEN/AKT Pathway In Vitro and In Vivo.
CONCLUSIONS: Our study indicated that propofol inhibited A549 cell growth, accelerated apoptosis via the miR-21/PTEN/AKT pathway in vitro, suppressed NSCLC tumor cell growth, and promoted apoptosis in vivo. Our findings provide new implications for propofol in cancer therapy and indicate that propofol is extremely advantageous in surgical treatment. PMID: 32925348 [PubMed - in process]

lncRNA BDNF-AS Attenuates Propofol-Induced Apoptosis in HT22 Cells by Modulating the BDNF/TrkB Pathway
This study aimed to investigate the involvement of BDNF-AS in propofol-induced apoptosis in HT22 cells. HT22 cells were treated with various concentrations of propofol at different time points. BDNF-AS was silenced using BDNF-AS-targeting siRNA. TrkB was antagonized by the TrkB inhibitor, ANA-12. Flow cytometry, quantitative reverse-transcription PCR, and western blotting were performed to analyze apoptosis and the expression of genes and proteins, respectively. In propofol-treated HT22 cells, BDNF-AS was upregulated, and BDNF was downregulated in a time- and dose-dependent manner. BDNF-AS downregulation mediated by siRNA ...

Endoplasmic Reticulum Stress is Involved in the Neuroprotective Effect of Propofol.
In this study, we found that propofol up-regulated BiP and attenuated tunicamycin-induced neural cell death. Propofol pretreatment also inhibited tunicamycin-induced up-regulation of C/EBP homologous protein (CHOP). We also found that propofol or tunicamycin alone increased the levels of spliced XBP1 (XBP1s) and cleaved activating transcription factor 6 (ATF6), an active form of ATF6. However, pretreatment with propofol attenuated the levels of phosphorylated protein kinase receptor-like ER kinase, phosphorylated elF2α, ATF4, and caspase-3, but failed to affect the increase of cleaved ATF6 and XBP1s, induced by tunicamyci...

Propofol Attenuates Lipopolysaccharide-Induced Reactive Oxygen Species Production Through Activation of Nrf2/GSH and Suppression of NADPH Oxidase in Human Alveolar Epithelial Cells
In conclusion, propofol reduced LPS-induced ROS production via inhibition of inflammatory factors and enhancement of Nrf2-related antioxidant defense, providing its cytoprotective evidence under inflammatory conditions.

Anesthetic agent propofol inhibits myeloid differentiation factor 88-dependent and independent signaling and mitigates lipopolysaccharide-mediated reactive oxygen species production in human neutrophils in vitro.
This study aimed to investigate the influence of PPF on lipopolysaccharide (LPS)-induced reactive oxygen species production in human neutrophils. We isolated neutrophils from the peripheral blood of 10 healthy male donors. Neither 1µg/ml LPS nor 10-150μmol/L PPF influenced the rate of neutrophil apoptosis, but PPF significantly inhibited LPS-mediated reactive oxygen species production in a dose-dependent manner. PPF inhibited LPS-induced expression of MyD88, tumor necrosis factor receptor-associated factor 6, and TRIF, but not the expression of interferon regulatory factor 3 or phosphorylation of p47(phox), p38-mitogen-a...

Propofol protects hippocampal neurons from apoptosis in ischemic brain injury by increasing GLT-1 expression and inhibiting the activation of NMDAR via the JNK/Akt signaling pathway.
Abstract Ischemic brain injury (IBI) can cause nerve injury and is a leading cause of morbidity and mortality worldwide. The neuroprotective effects of propofol against IBI have been previously demonstrated. However, the neuroprotective effects of propofol on hippocampal neurons are not yet entirely clear. In the present study, models of IBI were established in hypoxia-exposed hippocampal neuronal cells. Cell viability assay and apoptosis assay were performed to examine the neuroprotective effects of propofol on hippocampal neurons in IBI. A significant decrease in cell viability and a significant increase in cel...

Propofol inhibits invasion and growth of ovarian cancer cells via regulating miR-9/NF- κB signal.
Propofol inhibits invasion and growth of ovarian cancer cells via regulating miR-9/NF-κB signal. Braz J Med Biol Res. 2016 Dec 12;49(12):e5717 Authors: Huang X, Teng Y, Yang H, Ma J Abstract Propofol is one of the most commonly used intravenous anesthetic agents during cancer resection surgery. A previous study has found that propofol can inhibit invasion and induce apoptosis of ovarian cancer cells. However, the underlying mechanisms are not known. miR-9 has been reported to be little expressed in ovarian cancer cells, which has been related to a poor prognosis in patients with ovarian cancer. Studie...

Propofol inhibits proliferation, migration, and invasion but promotes apoptosis by regulation of Sox4 in endometrial cancer cells.
This study aimed to explore the effects of propofol on EC in vitro and in vivo. Different concentrations of propofol were used to treat Ishikawa cells. Colony number, cell viability, cell cycle, apoptosis, migration, and invasion were analyzed by colony formation, MTT, flow cytometry, and Transwell assays. In addition, the pcDNA3.1-Sox4 and Sox4 siRNA plasmids were transfected into Ishikawa cells to explore the relationship between propofol and Sox4 in EC cell proliferation. Tumor weight in vivo was measured by xenograft tumor model assay. Protein levels of cell cycle-related factors, apoptosis-related factors, matrix meta...
