Differential regulation of histamine H < sub > 1 < /sub > receptor-mediated ERK phosphorylation by G < sub > q < /sub > proteins and arrestins
Biochem Pharmacol. 2023 May 16:115595. doi: 10.1016/j.bcp.2023.115595. Online ahead of print.ABSTRACTGq protein-coupled histamine H1 receptors play crucial roles in allergic and inflammatory reactions, in which the phosphorylation of extracellular signal-regulated kinase (ERK) appears to mediate the production of inflammatory cytokines. ERK phosphorylation is regulated by G protein- and arrestin-mediated signal transduction pathways. Here, we aimed to explore how H1 receptor-mediated processes of ERK phosphorylation might be differentially regulated by Gq proteins and arrestins. For this purpose, we evaluated the regulator...

Baicalin inhibited both the Furin/TGF β1/Smad3/TSP-1 pathway in endothelial cells and the AKT/Ca < sup > 2+ < /sup > /ROS pathway in platelets to ameliorate inflammatory coagulopathy
In this study, the effects of baicalin, an active component of the traditional Chinese medicine Huangqin, on inflammatory coagulopathy were observed both in vivo and in vitro. In LPS-induced rats, baicalin ameliorated coagulation indexes, inhibited platelet hyperactivation and decreased the expression of thrombospondin-1 (TSP-1) in vessels. In cultured endothelial cells, baicalin decreased the expression of TSP-1 and collagen as well as the TNF-α-induced increase in the levels of TSP-1 and ICAM-1. Baicalin could significantly decrease the platelet adhesion on endothelial cells treated with TNF-α. Baicalin also could inhi...

Pharmacokinetics, Safety, and Tolerability of the siRNA JNJ ‐73763989 in Healthy Chinese Adult Participants
AbstractJNJ-73763989, composed of the 2 short-interfering RNA triggers JNJ-73763976 and JNJ-73763924, targets all hepatitis B virus messenger RNAs, thereby reducing all viral proteins. In this phase 1, single-site, open-label, parallel-group, randomized study, participants were given 1 subcutaneous injection of JNJ-73763989 (100 or 200  mg) to investigate the pharmacokinetics, safety, and tolerability of JNJ-73763989 in healthy Chinese adult participants. Plasma and urine pharmacokinetic parameters were determined for each trigger up to 48 hours after dosing. Eighteen participants, 9 per dose group, were enrolled. The me...

Brusatol Inhibits Proliferation and Invasion of Glioblastoma by Down-Regulating the Expression of ECM1
Brusatol (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. RNA-seq analysis indicated that Bru possibly achieved these effects through inhibiting the expression of extracellular matrix protein 1 (ECM1). Down-regulating the expression of ECM1 via transfecting siRNA could weaken the proliferation and invasion of glioblastoma cells and prom...

Compound Kushen Injection Protects Skin From Radiation Injury via Regulating Bim
Conclusion: We conclude that CKI represents a promising radio-protective agent with a potential differential beneficial effect on both cancer cells (inducing apoptosis) and HSF cells (providing radio-protection via inhibiting IR-induced apoptosis), via regulating Bim. Our study uncovers a novel mechanism by which CKI inhibits human cancer cell while protects skin from radiotherapy, indicating CKI might be a promising radio-protective drug.Clinical Trial Registration: Chinese Clinical Trial Registry (www.chictr.org.cn), identifier ChiCTR2100049164.

Uncovering Bupi Yishen Formula Pharmacological Mechanisms Against Chronic Kidney Disease by Network Pharmacology and Experimental Validation
Chronic kidney disease (CKD) is a leading public health problem with high morbidity and mortality, but the therapies remain limited. Bupi Yishen Formula (BYF) - a patent traditional Chinese medicine (TCM) formula - has been proved to be effective for CKD treatment in a high-quality clinical trial. However, BYF’s underlying mechanism is unclear. Thus, we aimed to reveal BYF pharmacological mechanism against CKD by network pharmacology and experimental studies. Network pharmacology-based analysis of the drug-compound-target interaction was used to predict the potential pharmacological mechanism and biological basis of BYF....

Chinese Herbal Preparation SaiLuoTong Alleviates Brain Ischemia via Nrf2 Antioxidation Pathway –Dependent Cerebral Microvascular Protection
Stroke is one of the most devastating diseases worldwide. The Chinese herbal preparation SaiLuoTong (SLT) capsule showed outstanding therapeutic effects on stroke and its sequelae. The aim of this study was to further elucidate its therapeutic mechanism. We duplicated a permanent cerebral ischemia model in rats by MCAO and used SLT (33 and 16.5 mg/kg) to intervene. The results showed SLT dose dependently decreased infarction volumes, relieved neuron degeneration and loss, and ameliorated neurological functions, and the dose of 33 mg/kg had statistical significance (compared with the model group, p < 0.05); SLT of 33 ...

Panax notoginseng saponins reduces the cisplatin-induced acute renal injury by increasing HIF-1 α/BNIP3 to inhibit mitochondrial apoptosis pathway
Biomed Pharmacother. 2021 Aug 9;142:111965. doi: 10.1016/j.biopha.2021.111965. Online ahead of print.ABSTRACTCisplatin (CDDP) may induce apoptosis of renal tubular epithelial cells (RTEC) and cause CDDP-induced acute kidney injury (CAKI) during cancer treatment, but yet lack of preventive measures and effective treatment. As a new Chinese herbal preparation, Panax notoginseng saponins (PNS) has been found to mitigate CDDP-induced CAKI through elevating the expression of HIF-1α in the rat model, according to the data from our previous works. However, the underlying link between HIF-1α and apoptosis has not been well eluci...

Tetramethylpyrazine Preserves the Integrity of Blood-Brain Barrier Associated With Upregulation of MCPIP1 in a Murine Model of Focal Ischemic Stroke
Tetramethylpyrazine (TMP), a prominent ingredient of Chinese herb Ligusticum chuanxiong Hort, is known to suppress neuroinflammation and protect blood-brain barrier (BBB) integrity. We investigated whether monocyte chemotactic protein-induced protein 1 (MCPIP1, also known as Regnase-1), a newly identified zinc-finger protein, plays a role in TMP-mediated anti-inflammation and neuroprotection. Male C57BL/6 mice were subjected to focal cerebral ischemia induced by middle cerebral artery occlusion (MCAO) for 2 h, followed by reperfusion for 24 h. TMP (25 mg/kg or 50 mg/kg) or vehicle was administered intraperitoneally 12...
