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 post ‐conditioning alleviates hepatic ischaemia reperfusion injury via BRG1‐mediated Nrf2/HO‐1 transcriptional activation in human and mice
Abstract To explore the effects of propofol post‐conditioning (PPC) on hepatic ischaemia/reperfusion injury (HIRI) and the potential mechanisms that might be involved in the interaction of Brahma‐related gene1(BRG1) and Nuclear‐related factor 2(Nrf2). Patients were randomized into PPC(n = 16) and non‐PPC(NPC)( n = 21) groups. Propofol(2 mg/kg) was infused within 10 min. of the onset of liver reperfusion during liver transplantation in the PPC group. Liver function tests, as well as Brg1, Nrf2, Heme oxygenase‐1(HO‐1) and NADPH:quinone oxidoreductase1(NQO1) expression levels were evaluated. CMV‐Brg1 mice were d...

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...

Propofol Regulates Neural Stem Cell Proliferation and Differentiation via Calmodulin-Dependent Protein Kinase II/AMPK/ATF5 Signaling Axis.
CONCLUSIONS: The results from study demonstrated that propofol inhibits the proliferation, differentiation, and migration of NSCs, and these effects are partially mediated by CaMkII/pS485/AMPK/ATF5 signaling pathway. PMID: 30303867 [PubMed - as supplied by publisher]

Calpain-2 plays a pivotal role in the inhibitory effects of propofol against TNF- α-induced autophagy in mouse hippocampal neurons.
Calpain-2 plays a pivotal role in the inhibitory effects of propofol against TNF-α-induced autophagy in mouse hippocampal neurons. J Cell Mol Med. 2020 Jul 06;: Authors: Li Y, He Z, Lv H, Chen W, Chen J Abstract Calpains are calcium-dependent proteases and play critical roles in neuronal autophagy induced by inflammation. Propofol has been reported to exert anti-inflammatory effects in neurons. We aimed to identify whether and how propofol-modulated calpain activity and neuron autophagy in response to tumour necrosis factor-α (TNF-α). Mouse hippocampal neurons were pre-treated with propofol and exp...

Propofol ameliorates renal ischemia/reperfusion injury by enhancing macrophage M2 polarization through PPAR γ/STAT3 signaling
Aging (Albany NY). 2021 Jun 10;13. doi: 10.18632/aging.203107. Online ahead of print.ABSTRACTPropofol (Pro) confers protection against renal ischemia/reperfusion (rI/R) injury through incompletely characterized mechanisms. Since Pro has shown net anti-inflammatory properties as part of its beneficial effects, we examined the potential role of Pro in the modulation of macrophage polarization status during both rI/R injury in vivo and exposure of cultured peritoneal macrophages (PMs) to hypoxia/reoxygenation (H/R). Rats were subjected to 45-min r/IR surgery or a sham procedure and administered PBS (vehicle) or Pro during the...

Propofol inhibits proliferation and migration of glioma cells by up-regulating lncRNA GAS5
Toxicol In Vitro. 2022 Jan 24:105321. doi: 10.1016/j.tiv.2022.105321. Online ahead of print.ABSTRACTPropofol has been documented to exhibit anti-tumor effects in cancers. However, the underlying mechanisms of its inhibition remain unclear. We conducted this study to investigate the effect of propofol on lncRNA GAS5 in glioma cells, and to probe the role of GAS5 in the anti-tumor effects of propofol. Human glioma cell line U251 were treated with propofol. Cell proliferation, migration, invasion, cell cycle and apoptosis were evaluated, and the expression of GAS5 was measured. After that, we knockdown the expression of GAS5 ...

Propofol Protects Myocardium From Ischemia/Reperfusion Injury by Inhibiting Ferroptosis Through the AKT/p53 Signaling Pathway
The molecular mechanism underlying the protective role of propofol against myocardial ischemia/reperfusion (I/R) injury remains poorly understood. Previous studies have shown that ferroptosis is an imperative pathological process in myocardial I/R injury. We hypothesized that propofol prevents myocardial I/R injury by inhibiting ferroptosis via the AKT/p53 signaling pathway. The ferroptosis-inducing agent erastin (E) and AKT inhibitor MK2206 (MK) were used to investigate the role of propofol in myocardial I/R injury. H9C2 cells treated without any reagents, erastin for 24 h, propofol for 1 h before adding erastin were as...

Tissue Cell. 2022 Aug 6;78:101891. doi: 10.1016/j.tice.2022.101891. Online ahead of print.ABSTRACTTo verify whether propofol alleviates liver ischemia-reperfusion injury (IRI) in mice by regulating Cyp2b10/ Cyp3a25 pathway. The liver I/R injury in vivo and in vitro model was constructed. The serum level of AST, ALT, ALP and ALB was detected using ELISA. The mRNA and protein expression of Cyp2b10 and Cyp3a25 were determined by qRT-PCR and western blot, respectively. The liver cell activity was assessed by MTT assay. The binding between Cyp2b10 and Cyp3a25 was evaluated by online website prediction, CoIP, and cell transfecti...
