DIA-PRM Proteomic Analysis of Phlegm-Dampness Constitution with Glucolipid Metabolic Disorders by the Intervention of Hua Tan Qu Shi Recipe.

ABSTRACT:

Background

Phlegm-dampness constitution as one of nine constitutions in traditional Chinese medicine (TCM) has been a high risk factor for glucolipid metabolic disorders (GLMD). Based on our previous findings, Hua Tan Qu Shi recipe (HTQSR) could effectively improve metabolic indicators of GLMD by targeting on phlegm-dampness constitution. However, the proteomic mechanisms of GLMD with the treatment of HTQSR targeting on phlegm-dampness constitution remain unknown.

Methods

Clinical participants from phlegm-dampness constitution with the prediabetic state (T), phlegm-dampness constitution with marginally elevated blood lipids (Z), and phlegm-dampness constitution before sickness (W) were included in this study, who orally took HTQSR for 12 weeks and, respectively, marked AT, AZ, and AW. Data-independent acquisition (DIA) and parallel reaction monitoring (PRM) were performed to identify the differential proteins; then, Venn analysis was used to investigate coexpressed and coregulated proteins. In addition, ingenuity pathway analysis (IPA) software was utilized to explore the related pathways and diseases and biofunctions.

Results

LXR/RXR activation, acute phase response signaling, and production of nitric oxide and reactive oxygen species in macrophages were obviously activated between the T and AT groups, as well as the Z and AZ groups. In contrast, these three pathways were inhibited between the W and AW groups. Importantly, one coexpressed and coregulated differential protein, B2MG, was validated by PRM among all groups.

Conclusions

This work firstly reported the underlying proteomic mechanisms of GLMD with the treatment of HTQSR targeting on phlegm-dampness constitution, indicating that intervention of phlegm-dampness constitution might be a novel strategy for the preventive treatment of GLMD.

Project description:BackgroundPrehypertension is the preclinical stage of hypertension, which is more likely to develop into hypertension than normal blood pressure. Although the body may experience pathological changes at this stage, there are often no symptoms. Chinese medicine constitution theory is widely used to assess an individual's health and disease status, which provides a new method for disease prevention. The phlegm-dampness constitution (PDC) is the main constitution in prehypertension. Dysbiosis of the intestinal flora is considered to be related to the development of hypertension. However, the characteristics of the intestinal flora in prehypertensive populations with PDCs are still unknown.Methods16S rRNA gene sequencing of fecal samples was performed in this study, which included 30 prehypertensive subjects with PDCs, 30 nonphlegm-dampness constitution (NPDC) prehypertensive individuals with balanced constitution, and 30 ideal blood pressure subjects with balanced constitution (BC). On the basis of the composition of the intestinal flora, a random forest classifier was constructed to screen the specific bacteria of the prehypertensive PDC population, and the diagnostic efficiency was determined by the area under the curve (AUC).ResultsAt the phylum level, the abundance of Bacteroidetes decreased in the PDC group compared with the NPDC group. Bacteroides was the most important genus at the genus level. Compared with those in the NPDC or BC group, the relative abundances of o_RF39, f_Porphyromonadaceae, f_Christensenellaceae, g_parabacteroides, and g_nitrobacteria in the PDC group were significantly greater. The random forest analysis results revealed that Alistipes, Butyricimonas, Odoribacter, Parabacteroides, and Corynebacterium are bacterial genera that significantly differ between the PDC and NPDC groups and greatly contribute to group differentiation. Receiver operating characteristic (ROC) analysis revealed that the AUC range of differential bacteria and its combined diagnostic model ranged from 0.653 (95% CI: 0.511-0.794) to 0.706 (95% CI: 0.573-0.838), suggesting that it is a potential risk marker for phlegm-dampness constitution with prehypertension.ConclusionsOur study indicates that PDC individuals with prehypertension can be distinguished from NPDC individuals according to their gut microbiome characteristics. Prevention and treatment measures based on these biomarkers may be beneficial in opening new ideas and directions for identifying more aggressive and effective interventions for prehypertensive populations.

Project description:BackgroundConstitution in traditional Chinese medicine (TCM) plays a key role in the genesis, development, and prognosis of diseases. Phlegm-dampness constitution (PDC) is one of the nine constitutions in TCM, susceptible to metabolic disorders, which is mainly manifested by profuse phlegm, loose abdomen, and greasy face. Epidemiologic, genomic, and epigenetic studies have been carried out in previous works, confirming that PDC represents a distinctive population with microcosmic changes related to metabolic disorders. However, whether long noncoding RNAs (lncRNAs) play a regulatory role in metabolic disease in subjects with PDC remains largely unknown. We aimed to investigate distinct lncRNA and mRNA expression signatures and lncRNA-mRNA regulatory networks in the phlegm-dampness constitution (PDC).MethodsThe peripheral blood mononuclear cells (PBMCs) were isolated from the subjects with PDC (n = 13) and balanced constitution (BC) (n = 9). The profiles of lncRNAs and mRNAs in PBMCs were analyzed using microarray and further validated with RT-qPCR. Subsequently, pathway analysis was performed to investigate the function of differentially expressed mRNAs by using Ingenuity Pathway Analysis (IPA).ResultsResults suggested that some mRNAs, which were regulated by the differentially expressed lncRNAs, were mainly enriched in lipid metabolism and immune inflammation-related pathways. This was consistent with the molecular characteristics of previous studies, indicating that the clinical characteristics of metabolic disorders in PDC might be regulated by lncRNAs. Furthermore, by making coexpression network construction as well as cis-regulated target gene analysis, several lncRNA-mRNA pairs with potential regulatory relationships were identified by bioinformatic analyses, including RP11-317J10.2-CA3, RP11-809C18.3-PIP4K2A, LINC0069-RFTN1, TTTY15-ARHGEF9, and AC135048.13-ORAI3.ConclusionsThis study first revealed that the expression characteristics of lncRNAs/mRNAs may be potential biomarkers, indicating that the distinctive physical and clinical characteristics of PDC might be partially attributed to the specific expression signatures of lncRNAs/mRNAs.

Project description:According to traditional Chinese medicine (TCM) constitutional theory, individuals with phlegm-dampness constitution (PDC) are at increased risk for metabolic disorders. Previous studies have indicated that PDC individuals exhibit gene expression changes associated with metabolic disorders, even individuals with normal metabolic indices. However, the biological mechanisms underlying these changes remain unclear. The gut microbiota has recently emerged as a promising avenue for elucidating TCM principles. Here, we revealed that individuals with PDC have distinct gut microbiota and serum metabolite profiles. A decrease in phytosphingosine was associated with increased PDC scores and metabolic disorder severity. Subsequent experiments demonstrated that Flavonifractor plautii can biosynthesize phytosphingosine, which was also negatively correlated with the PDC score. Interestingly, both F. plautii and phytosphingosine levels decreased in PDC subjects with normal metabolic indices. Fecal transplantation from these individuals accelerated the development of metabolic disorders in mice. However, supplementation with F. plautii and phytosphingosine ameliorated metabolic disorders by increasing phytosphingosine levels in the gut‒hepatic axis. Mechanistic investigations confirmed that phytosphingosine can directly bind to hepatic peroxisome proliferator-activated receptor α (PPARα) and activate its nuclear transcription activity, thereby regulating downstream gene expression related to glucose‒lipid metabolism. Our research indicates that the decrease in F. plautii and its product, phytosphingosine, contributes to gene expression changes related to metabolic disorders in PDC individuals and increases their susceptibility to metabolic disorders. These findings suggest that diagnosing PDC may be beneficial for identifying at-risk populations among apparently healthy individuals, thereby advancing the broader field of metabolic disorder prevention and TCM integration.

Project description:BackgroundObesity is conventionally considered a risk factor for multiple metabolic diseases, such as dyslipidemia, type 2 diabetes, hypertension, and cardiovascular disease (CVD). However, not every obese patient will progress to metabolic disease. Phlegm-dampness constitution (PDC), one of the nine TCM constitutions, is considered a high-risk factor for obesity and its complications. Alterations in the gut microbiota have been shown to drive the development and progression of obesity and metabolic disease, however, key microbial changes in obese patients with PDC have a higher risk for metabolic disorders remain elusive.MethodsWe carried out fecal 16S rRNA gene sequencing in the present study, including 30 obese subjects with PDC (PDC), 30 individuals without PDC (non-PDC), and 30 healthy controls with balanced constitution (BC). Metagenomic functional prediction of bacterial taxa was achieved using PICRUSt.ResultsObese individuals with PDC had higher BMI, waist circumference, hip circumference, and altered composition of their gut microbiota compared to non-PDC obese individuals. At the phylum level, the gut microbiota was characterized by increased abundance of Bacteroidetes and decreased levels of Firmicutes and Firmicutes/Bacteroidetes ratio. At the genus level, Faecalibacterium, producing short-chain fatty acid, achieving anti-inflammatory effects and strengthening intestinal barrier functions, was depleted in the PDC group, instead, Prevotella was enriched. Most PDC-associated bacteria had a stronger correlation with clinical indicators of metabolic disorders rather than more severe obesity. The PICRUSt analysis demonstrated 70 significantly different microbiome community functions between the two groups, which were mainly involved in carbohydrate and amino acid metabolism, such as promoting Arachidonic acid metabolism, mineral absorption, and Lipopolysaccharide biosynthesis, reducing Arginine and proline metabolism, flavone and flavonol biosynthesis, Glycolysis/Gluconeogenesis, and primary bile acid biosynthesis. Furthermore, a disease classifier based on microbiota was constructed to accurately discriminate PDC individuals from all obese people.ConclusionOur study shows that obese individuals with PDC can be distinguished from non-PDC obese individuals based on gut microbial characteristics. The composition of the gut microbiome altered in obese with PDC may be responsible for their high risk of metabolic diseases.

Project description:BackgroundConsidered an effective supplementary therapy, traditional Chinese medicine (TCM) has been widely applied in the treatment of coronary heart disease (CHD). In this study, we aim to investigate the effects and mechanisms of Huo-Tan-Chu-Shi decoction (HTCSD, an in-hospital TCM prescription) in the treatment of CHD with the phlegm-damp syndrome in mice by non-targeted metabolomics with liquid chromatography-mass spectrometry (LC-MS)/MS.MethodsA CHD with phlegm-damp syndrome model was established with ApoE-/- mice by subcutaneous injection with isoproterenol combined with high temperature, high humidity, and a high-fat diet, and divided into the HTCSD and Tanshi groups. C57BL/6 mice were set as the control group with an ordinary environment and diet. After administration, electrocardiogram (ECG), interventricular septum thickness (IVS) and left ventricular posterior wall thickness (LVPW), serum levels of creatine phosphokinase-Mb (CK-MB), cardiac troponin T (cTnT), lactic dehydrogenase (LDH) and oxidized low-density lipoprotein (oxLDL), and myocardial histopathological changes were recorded to assess myocardial damage. LC-MS/MS was applied to demonstrate the serum metabolic profile and explore potential mechanisms.ResultsThe obvious depressions of the ST segment and T wave presented in the ECG of Tanshi mice, while the depressions in ECG of HTCSD mice were significantly reduced. Compared with the control group, IVS, LVPW, and serum levels of CK-MB, cTnT, LDH, and oxLDL increased greatly in the Tanshi group, while these indicators decreased remarkably in the HTCSD group compared with those of the Tanshi group. Histopathology showed severe structural disorder, necrosis, and fibrosis of myocardial cells in Tanshi mice, which were alleviated in HTCSD mice. Metabonomics analysis showed obvious metabolic alterations among the experimental mice and revealed that the relevant metabolic pathways mainly included phospholipid metabolism, necroptosis, and autophagy.ConclusionsHTCSD has a certain therapeutic effect in mice with CHD with phlegm-damp syndrome via reducing myocardial ischemia, hypertrophy, and fibrosis. The underlying mechanisms involve the regulation of phospholipid metabolism, necroptosis, and autophagy.

Project description:BackgroundGu-ben-hua-shi (AESS) formula is a clinical experienced prescription from Guangdong Hospital of Traditional Chinese Medicine (TCM), which is used to treat atopic dermatitis (AD). Our previous work has shown that AESS has therapeutic effect on AD by regulating yes-associated protein (YAP). AESS formula has multi-component and multi-target characteristic, and need to be analyzed by systematic chemical profiling and network pharmacology technology, as well as verification of key signaling pathways. Therefore, this study aimed at investigating the efficacy and effect of AESS formula in the treatment of AD and its effect on NLRP3 signaling pathway.MethodsThe components of AESS formula were analyzed and identified by ultra high performance liquid chromatography/tandem mass spectrometry (UHPLC- MS/MS), and the potential mechanism of AESS formula in the treatment of AD was predicted by network pharmacology approach, with detected main components, and the potential components targeted NOD-like receptor thermal protein domain associated protein (NLRP3) signaling pathway [Direct binding with NLRP3, apoptosis-associated speck-like protein (ASC) and Caspase-1] were assessed using molecular docking. AD-like symptoms were constructed by DNCB induced BALB/c mice. The effect of AESS formula on dorsal skin structure in AD-like mice was observed using H&E staining. Furthermore, the western blotting experiment explored the expression of the NLRP3 pathway protein.ResultsBy UHPLC-MS/MS analysis, 91 compounds were detected in AESS formula, and 76 of them were identified, while by network pharmacological analysis, 1500 component targets were obtained, and 257 of them were obtained by intersection with eczema targets. Then one of the key pathways, nucleotide-binding oligomerization domain (NOD)-like signaling pathway was obtained by KEGG enrichment analysis. Molecular docking results showed 24 main components could effectively combine with ASC and Caspase-1 (≤-7 kcal/mol). The animal experiment results further showed that AESS formula alleviates symptoms in AD-like mice. ELISA kit results showed that the expression of IL-1β and IL-18 in serum was inhibited after AESS treatment. Additionally, western blotting analysis showed that the expressions of ASC, Caspase-1 and NLRP3 protein expression in the skin tissue of mice were down-regulated after AESS treatment. The experimental results show that AESS formula inhibited the expression of NLRP3 signaling pathway for the treatment of AD.ConclusionsAESS formula can improve AD symptoms in mice by inhibiting the activation of NLRP3 inflammasome and the expression of the related downstream inflammatory cytokines.
