Abstract
INTRODUCTION Previous research has shown that an aqueous extract of Humulus japonicus (EH) can ameliorate hypertension, nonalcoholic fatty liver disease, and oxidative stress in adipocytes by activating the thermogenic pathway. However, the effects of an ethanol (30%) extract of EH on obesity are unknown. METHODS Various protein expression levels in fully differentiated 3T3-L1 adipocytes were assessed by Western blotting. Lipid deposition in 3T3-L1 adipocytes was examined by oil red O staining. The MTT assay was used to evaluate adipocyte viability. Caspase 3 activity and glycerol release were determined using commercial assay kits. RESULTS In this study, we discovered that EH treatment inhibited lipogenesis and promoted lipolysis in both differentiated 3T3-L1 adipocytes and adipose tissue of mice fed a high-fat diet. EH treatment also increased phosphorylated protein kinase A (PKA) levels while reducing p38 phosphorylation. When H89, a PKA inhibitor, was used, the effects of EH on lipogenic lipid accumulation and lipolysis in 3T3-L1 adipocytes were eliminated. Treatment with luteolin 7-O-β-d-glucoside (LU), the major active compound in EH, also suppressed lipid deposition and p38 phosphorylation but enhanced lipolysis in 3T3-L1 adipocytes. These changes were abrogated by H89. CONCLUSION These findings indicate that EH containing LU reduces lipogenesis and stimulates lipolysis via the PKA/p38 signaling pathway, leading to an improvement in obesity in mice. Therefore, our study suggested that EH could be a promising therapeutic agent for treating obesity.

Abstract
In this study, an Angelica keiskei (A. keiskei) Jiaosu (FAK) was prepared by yeast fermentation to investigate its anti-obesity effect on high-fat diet (HFD)-fed mice. 70 SPF grade male C57BL/6J mice were randomly divided into 7 groups (n = 10): blank control group (N), high-fat model group (M), positive control group (Orl), unfermented control group (NF), high-dose intervention group (FH), medium-dose intervention group (FM), and low-dose intervention group (FL). The results showed that FAK intervention significantly reduced the body weight, Lee's index and liver index of HFD-fed mice (P < 0.05). Compared with M group, the serum levels of triglyceride (TG), total cholesterol (TC), leptin and glucose (GLU) in FH group were remarkably decreased and that of interleukin-27 (IL-27) were increased (P < 0.05). The levels of TG, and TC in the liver of mice were also markedly decreased in the FH group (P < 0.05). HE staining results showed that the liver cells in the three intervention groups had less degeneration and fatty vacuoles in the cytoplasm, and the liver cords were orderly arranged compared with that of M group. Furthermore, FAK significantly inhibited epididymal adipose tissue cell expansion induced by HFD. FAK up-regulated the protein expression levels of p-AMPK and PPARα to promote lipolysis and down-regulated the expression of PPARγ to reduce lipid synthesis (P < 0.05). Additionally, the results of gut microbiota showed that after the intervention, a decrease trend of F/B value and Deferribacterota was noticed in the FH group compared with M group. At the genus level, FAK intervention significantly increased that of Ileiobacterium compared to the M group (p < 0.05). A rising trend of norank_f_Muribaculaceae, Lactobacillus, and Bifidobacterium were also observed in the HF group. Conclusively, these findings demonstrated that FAK intervention can effectively improve obesity in mice caused by HFD and the potential mechanisms was related to the regulation of serum levels of leptin and IL-27, lipogenesis and lipolysis in adipose tissue and gut microbiota composition.

Abstract
Humulus japonicus (HJ) is an herbal medicine, which has been reported as being antioxidative and anti-inflammatory. The present study aimed to investigate the effect of oral administration of HJ water extract (HJW) on cognitive function through the cholinergic system in Alzheimer's disease (AD) mouse models. Institute of Cancer Research mice injected with beta-amyloid (Aβ) (1-42) (i.c.v.) and APP/PS1 transgenic (TG) mice were orally administered with HJW at 500 mg/kg/day for 3 weeks. Aβ-injected mice and APP/PS1 TG mice showed cognitive dysfunction, which was evaluated by various behavioral tests. HJW treatment significantly attenuated memory impairments in Aβ-injected mice and APP/PS1 TG mice. Aβ injection decreased acetylcholine (ACh) concentrations and choline acetyltransferase (ChAT) activity, and increased acetylcholinesterase (AChE) activity. These cholinergic impairments were also found in APP/PS1 TG mice. HJW significantly attenuated cholinergic alterations in Aβ-injected mice and TG mice. In addition, HJW significantly decreased Aβ plaque deposition in the cerebral cortex and hippocampus of TG mice. Therefore, the present study demonstrated that HJW protected against AD-related memory impairments via enhancing the cholinergic system and inhibiting Aβ plaque deposition.

Ameliorative Effects of Humulus japonicus Extract and Polysaccharide-Rich Extract of Phragmites rhizoma in Rats with Gastrointestinal Dysfunctions Induced by Water Avoidance Stress. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:9993743.

Abstract
Chronic stress can cause the gastrointestinal disorders characterized by an altered bowel movement and abdominal pain. Studies have shown that Humulus japonicus extract (HJE) has anti-inflammatory and antidiarrheal effects, and Phragmites rhizoma extract (PEP) has antioxidative and antistress effects. The present study aimed to investigate the possible effects of HJE and PEP in rat models with stress-induced gastrointestinal dysfunctions. The rats were exposed to water avoidance stress (WAS, 1 h/day) for 10 days to induce gastrointestinal disorders. We found that WAS significantly increased fecal pellet output during 1 h stress, gastric emptying, colonic contractility, and permeability compared to the normal rats. Pretreatment with HJE and PEP (0.25 and 0.5 mL/kg, both administered separately) improved the increased gastric emptying and colonic contractility induced by electrical field stimulation, acetylcholine, and serotonin and also alleviated the increased colonic permeability. HJE and PEP also increased the claudin-1 and occludin expressions, reduced by WAS. WAS increased the concentration of TNF-α and TBARS and reduced FRAP. HJE and PEP recovered these effects. HJE and PEP improved the gastrointestinal disorders induced by WAS by upregulating the tight junction protein, possibly acting on cholinergic and serotonergic receptors to abolish the colonic hypercontractility and hyperpermeability and degradation of inflammatory cytokines via an antioxidant effect.

Abstract
Alcohol induces liver injury related to oxidative stress and inflammatory responses. The purpose of this study was to investigate the hepatoprotective effect of Humulus japonicus extract (HJE) against alcohol-induced liver injury. Furthermore, we investigated the mechanisms of the protective effect of HJE on alcohol-induced liver injury. The pretreatment of HJE decreased the levels of aspartate aminotransferase, alanine aminotransferase, triglyceride, and total cholesterol in the plasma, suppressed the malondialdehyde, myeloperoxidase, and enhanced the activities of superoxide dismutase, glutathione, and catalase. The inhibitory effect of HJE against oxidative stress may be associated with the upregulation of nuclear factor erythroid 2-related factor 2 and its target gene heme oxygenase-1. Moreover, HJE inhibited the pro-inflammatory cytokines (tumor necrosis factor alpha, interleukin-1 beta) by downregulating toll-like receptor 4, myeloid differentiation primary response 88, and nuclear factor kappa B p65. These findings provide evidence for the elucidation of the hepatoprotective mechanisms for HJE.

Abstract
An aqueous extract of Humulus japonicus (AH) has been documented to ameliorate hypertension and non-alcoholic fatty liver disease (NAFLD). Here, we investigated the effects of an aqueous extract of AH on thermogenesis and palmitate-induced oxidative stress in adipocytes. To verify the effect of AH on browning, we measured the expression levels of specific markers in 3T3-L1 adipocytes using qPCR and Western blotting, respectively. To assess the role of oxidative stress, cells were stained with DCFDA and observed by fluorescence microscopy. AH increased the expression of brown adipose tissue-specific markers. Additionally, it induced fatty acid oxidation and lipolysis and suppressed both lipogenic markers and lipid accumulation. Furthermore, AH ameliorated hydrogen peroxide-induced oxidative stress. Enhanced expression of these markers contributed to fat browning, fatty acid oxidation and lipolysis of 3T3-L1 adipocytes via the AMP-activated protein kinase (AMPK) and peroxisome proliferator-activated receptor delta (PPARδ) signaling pathways. Moreover, AMPK and PPARδ resulting in protective effects of AH against oxidative stress. In sum, AH could promote the browning, lipolysis and thermogenesis in 3T3-L1 adipocytes and would suppress the hydrogen peroxide-induced oxidative stress and lipogenesis during differentiation. We therefore suggest that AH could be used as a potential candidate for treating obesity and related metabolic disorders.
