The angiotensin-converting enzyme(ACE)inhibitory peptide NCW derived from Mizuhopecten yessoensis has been demonstrated to have significant in vivo anti-hypertensive effects,however,its anti-hypertensive mechanism is still not fully clarified.This study established a UPLC-Q-TRAP-MS/MS-based widely targeted kidney metabolomics approach to explore the changes of kidney metabolic profiles and to clarify the antihypertensive mechanism of peptide NCW in spontaneously hypertensive rats(SHRs).Multivariate statistical analysis indicated that the kidney metabolic profiles were clearly separated between the SHR-NCW and SHRUntreated groups.A total of 85 metabolites were differentially regulated,and 16 metabolites were identified as potential kidney biomarkers,e.g.,3-hydroxybutyrate,malonic acid,deoxycytidine,and L-aspartic acid.The peptide NCW might regulate kidney metabolic disorder of SHRs to alleviate hypertension by suppressing inflammation and improving nitric oxide production under the regulation of linoleic acid metabolism,folate related pathways,synthesis and degradation of ketone bodies,pyrimidine metabolism,β-alanine metabolism,and retinal metabolism.

Akkermansia muciniphila play an important in ameliorating obesity but is not allowed for direct consumption in most countries.To date,microbiota-directed foods selectively promote the targeted human gut microbes,providing a strategy for A.muciniphila enhancement.Multiple studies have indicated the potential regulation of the polyphenol on A.muciniphila.Therefore,a polyphenol screening based on A.muciniphila upregulation was performed in mice.Chlorogenic acid(CGA)exhibited a greater response to A.muciniphila upregulation.Furthermore,we found that CGA did not directly promote A.muciniphila growth or mucin secretion.Microbiome and metabolomics revealed that the increased abundance of A.muciniphila resulted from the inhibition of CGA on Desulfovibrio and Alistipes and the influence of docosahexaenoic acid,β-hydroxybutyrate,and N-acetyl-lactosamine.Finally,to confirm the regulation of CGA on A.muciniphila under disease conditions,high-fat diet-fed mice were established.The results showed CGA promoted A.muciniphila growth,and we expectedly found that CGA suppressed the augment in body weight of mice,significantly attenuated adipose tissue abnormality,provided liver protection and improved gut barrier integrity.These results suggest that CGA inhibits the development of obesity.Overall,our results indicate that microbiota-directed food is a promising approach for the treatment of obesity.

Blautia has attracted attention because of its potential efficacy in ameliorating host energy metabolism and inflammation.This study aims to investigate the influences of Blautia producta D4 on colitis induced by dextran sulfate sodium(DSS)and to reveal the underlying mechanisms.Results showed that B.producta D4 intervention significantly relieved body weight loss,and suppressed the elevation of pro-inflammatory cytokines(including interleukin-6(IL-6),tumor necrosis factor-α(TNF-α),and interleukin-1β(IL-1β))and excessive oxidative stress(myeloperoxidease(MPO)activity,superoxide dismutase(SOD)activity,glutathione peroxidase(GSH-Px)activity,and malondialdehyde(MDA)level)in colitis mice.Moreover,the concentrations of tight junction proteins(occludin,claudin-1,and ZO-1)related to the intestinal barrier were obviously elevated,and colitis-related TLR4/NF-κB pathway activation was remarkably inhibited after B.producta D4 intervention.The intestinal microbial disorder was evidently ameliorated by increasing the relative abundance of Clostridium sensu stricto 1,Bifidobacterium,GCA-900066225,Enterorhabdus,and reducing the relative abundance of Lachnospiraceae NK4A136 group.In conclusion,oral administration of B.producta D4 could ameliorate DSS-induced colitis by suppressing inflammatory responses,maintaining the intestinal barrier,inhibiting TLR4/NF-κB pathway,and regulating intestinal microbiota balance.These results are conducive to accelerate the development of B.producta D4 as a functional probiotic for colitis.

Partridge tea (Mallotus fortians Muell-Arg)， an important and widely consumed substitute tea in Hainan， possessed multi-biological activities. This study investigated the composition and content of phenolics-rich extracts purified from partridge tea， and then explored the effect of partridge tea polyphenol extract (PTE) on glucose and lipid metabolism disorders in type 2 diabetes mellitus (T2DM) mice. The results showed that the dominant components in PTE included rutin (152.78 ± 2.93) mg/g， 3-chlorogenic acid (85.81 ± 3.48) mg/g， caffeic acid (63.78 ± 1.86) mg/g， catechin (12.10 ± 1.41) mg/g， gallic acid (5.24 ± 0.12) mg/g， kaempferitrin， ellagic acid， ferulic acid， caffeic acid methylester， and geraniin. After 6 weeks of PTE intervention， glucose tolerance， insulin resistance， and pancreatic β-cell function in T2DM mice have significantly improved. This improvement was corroborated by an increase in glucagon-like peptide-1 (GLP-1); homeostasis model assessment of β-cell function (HOMA-β)， glycogen， insulin protein expression， and reduction of insulin， glycosylated serum protein (GSP)， homeostasis model assessment-insulin resistance index (HOMA-IR)， glucagon protein expression. The supplementation of PTE also seems to alleviate the inflammatory response， as evidenced by a decrease in endotoxin and inflammatory cytokine levels. Hyperglycemia-induced mitochondrial damage is alleviated by PTE intervention. Hematoxylin-eosin staining (H & E staining) and lipid profile analysis indicate that PTE intervention can help regulate lipid metabolism disorders. In addition， the integration of metabolomics and transcriptomic analysis indicates that PTE intervention could regulate glycolipid metabolism pathways related to T2DM， including insulin， AMPK， bile acid metabolism and glutathione metabolism signaling pathways. More importantly， the validation results from reverse transcription-polymerase chain reaction (RT-PCR) confirmed that the expressions of Scd1， Fasn， Hmgcr， and Slc2a4 (related to glycolipid metabolism) were cons
