Natural carbazole alkaloid murrayafoline A displays potent anti-neuroinflammatory effect by directly targeting transcription factor Sp1 in LPS-induced microglial cells
Bioorg Chem. 2022 Sep 28;129:106178. doi: 10.1016/j.bioorg.2022.106178. Online ahead of print.ABSTRACTNeuroinflammation is a leading cause for neurological disorders. Carbazole alkaloids, isolated from the medicinal plants of Murraya species (Rutaceae), have exhibited wide pharmacological activities particularly for neuroinflammation. However, its underlying cellular targets and molecular mechanisms still remain unclear. In current study, we found that murrayafoline A (MA), a carbazole alkaloid obtained from Murraya tetramera, potently inhibited the production of neuroinflammation mediators, such as nitric oxide (NO), TNF-...

α-Iso-cubebene attenuates neointima formation by inhibiting HMGB1-induced monocyte to macrophage differentiation via suppressing ROS production
Int Immunopharmacol. 2022 Aug 5;111:109121. doi: 10.1016/j.intimp.2022.109121. Online ahead of print.ABSTRACTα-Iso-cubebene (ICB) is a dibenzocyclooctadiene lignin contained in Schisandra chinensis, a medicinal herb used to improve cardiovascular symptoms. To investigate the mechanisms involved, the effects of ICB on cellular production of reactive oxygen species (ROS) was determined using cultured human THP-1 cells. When THP-1 cells were stimulated with HMGB1, cellular concentration of ROS was increased in dose- and time-dependent manners. These increases were significantly attenuated in cells pretreated with NADPH oxida...

Synthesis and anti-melanoma effect of 3-O-prenyl glycyrrhetinic acid against B16F10 cells via induction of endoplasmic reticulum stress-mediated autophagy through ERK/AKT signaling pathway
In this study, 4-phenylbutyric acid (4PBA, a chemical chaperone) and small interference RNA (siRNA) knockdown of C/EBP Homologous Protein (CHOP)/growth arrest- and DNA damage-inducible gene 153(GAD153) blocked NPC-402-mediated autophagy induction, thus confirming the role of ER stress and autophagy in melanoma cell death. NPC-402 induced oxidative stress and apoptosis in melanoma cells, which were effectively mitigated by treatment with N-acetylcysteine (NAC). In vivo studies showed that intraperitoneal (i.p.) injection of NPC-402 at 10 mg/kg (5 days in 1 week) significantly retarded angiogenesis in the Matrigel plug assay...

Storax Protected Primary Cortical Neurons from Oxygen-Glucose Deprivation/Reoxygenation Injury via Inhibiting the TLR4/TRAF6/NF- κB Signaling Pathway
This study aimed to elucidate the neuroprotective effects and underlying mechanisms of storax on oxygen-glucose deprivation/reoxygenation (OGD/R) in injured cortical neurons. The cortical neurons of Wistar rats were primarily cultured in vitro. TheTUNELmethod and CM-H2DCFDA probe were used to detect cell apoptosis and reactive oxygen species (ROS) expression. Enzyme-linked immunosorbent assay, reverse transcription-polymerase chain reaction, and Western blot were used to detect the expression of inflammatory cytokines and proteins of the TLR4/TRAF6/NF-κB signaling pathway. Immunofluorescence was used to measure NF-κB nuc...

New mechanism of nephrotoxicity of triptolide: Oxidative stress promotes cGAS-STING signaling pathway
In this study, we show that triptolide activated the cGAS-STING signaling pathway in kidney tubular cells in vivo and in vitro. Renal injury models were established in BALB/c mice and human tubular epithelial cells using TPL. We found that TPL enhanced the phosphorylation levels of STING, TBK1 and IRF3, and upregulated the expression of IFNβ, which is the production of cGAS-STING signaling pathway. STING inhibitor C176 had protective effects in TPL-induced nephrocyte damage. STING siRNA down regulated the expression level of IFNβ. In addition, triptolide induced an increase in protein levels of the transcription factor B...

Tetramethylpyrazine Alleviates Endothelial Glycocalyx Degradation and Promotes Glycocalyx Restoration via TLR4/NF- κB/HPSE1 Signaling Pathway During Inflammation
Front Pharmacol. 2022 Jan 3;12:791841. doi: 10.3389/fphar.2021.791841. eCollection 2021.ABSTRACTTetramethylpyrazine (TMP), a Chinese traditional herbal extraction widely used in treating cardiovascular diseases, could attenuate vascular endothelial injuries, but the underlying mechanism remains incomprehensive. Vascular glycocalyx coating on the endothelium would be damaged and caused endothelial dysfunction in the inflammatory microenvironment, which was the initial factor of morbidity of many vascular diseases, such as atherosclerosis (AS). Here, we thoroughly investigated the molecular mechanism of TMP on vascular endot...

GSE184859 Brusatol inhibits proliferation and invasion of glioblastoma by down-regulating the expression of ECM1
Contributors : Cai Lin ; Dai Zhang'an ; Lu XiangheSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensBrusatol (Bru), a Chinese herbal extract, has a variety of anti-tumor effects. However, little is known regarding its role and underlying mechanism in glioblastoma cells. Here, we found that Bru could inhibit the proliferation of glioblastoma cells in vivo and in vitro. Besides, it also had an inhibitory effect on human primary glioblastoma cells. In order to further study the underlying mechanism of Bru ’s action on GBM, we performed RNA sequencing array on GBM cells treated by Bru wit...
