Up to now limited information is available concerning the activity of its main phytoconstituents towards the main targets of the cholesterol homeostasis. In the present study, the effects of bergamot peel extract and isolated constituents, namely glycosidic and non-glycosidic flavonoids, one coumarin and one limonoid on the low-density lipoprotein receptor (LDLR) and proprotein convertase subtilisin/kexin type 9 (PCSK9) were evaluated by using cultured HuH7 cell line. Furthermore, for the first time the effects of bergamot peel extract were studied to describe a potential hypolipidemic action. Significant differences were observed due to glycosylation and different substitution on flavanone moiety (<em>O</em>-methylation). Considering the thirteen isolated compounds, both naringenin-7-<em>O</em>-rutinoside (NA-rut) and apigenin-6,8-<em>C</em>-glicoside induced the expression of the LDLR while no effect was observed on PCSK9. However, hesperetin (HE) and its derivatives, hesperetin-7-<em>O</em>-glucoside and hesperetin-7-<em>O</em>-neohesperidoside (HE-glu, HE-neo) and eriodictyol (ER) showed a statin-like effect since a significant increase of both LDLR and PCSK9 expression were detected. Furthermore, bergamot peel extract (BE) firstly demonstrated a significant reduction of PCSK9 expression, indicating a potential adjuvant action to statins. BE, HE-neo, and NA-rut reduced intracellular sterols and the expression of PCSK9 transcription factor HNF1-α. BE also significantly improved the LDL uptake u Huh7 cells. Based on the present data, bergamot peel constituents can play a role in the management of hypercholesterolemia, on one hand they may produce an adjuvant action in combination with statins, while on the other hand they may have a statin-like effect. Additionally, BE may be a good candidate as an adjuvant to statins action.</p></div>","PeriodicalId":360,"journal":{"name":"Journal of Functional Foods","volume":"108 ","pages":"Article 105724"},"PeriodicalIF":5.6,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"3461684","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Network pharmacology analysis predicted that the potential molecular mechanism of Gyps/Caps combination against hyperlipidemia was mainly associated with steroid metabolism, lipid synthesis and inflammatory response. Animal experiment demonstrated that Gyps/Caps combination lowered the liver weight, liver index, serum lipid profile and hepatic cholesterol content, improved liver function by reducing the serum markers of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), thereby relieving the hepatic injury. Moreover, Gyps/Caps combination inhibited oxidative stress by decreasing the lactic dehydrogenase (LDH) activity and increasing the superoxide dismutase (SOD) activity. Western blotting result suggested that Gyps/Caps combination could upregulate the expressions of peroxisome proliferator-activated receptors γ (PPARγ), liver X receptor α (LXRα), ATP-binding cassette transporter A1 (ABCA1) and ATP-binding cassette transporter G1 (ABCG1) in the liver tissue. Cellular experiment revealed that the combination treatment protected RAW264.7 cells from ox-LDL induction through inhibiting apoptosis, lipid-decreasing and anti-inflammation, and caused the dramatic enhancement on PPARγ expression.
