A high-fat diet-induced C57BL/6N mouse model of non-alcoholic fatty liver disease (NAFLD) was established. The effect and mechanism of Raw Bowl Tea polyphenols (RBTP) on preventing NAFLD via regulating intestinal function were observed. The serum, liver, epididymis, small intestine tissues, and feces of mice were examined by biochemical and molecular biological methods, and the composition of RBTP was analyzed by HPLC assay. The results showed that RBTP could effectively reduce the body weight, liver weight, and liver index of NAFLD mice. The serum effects of RBTP were: (1) decreases in alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (AKP), total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C), D-lactate (D-LA), diamine oxidase (DAO), lipopolysaccharide (LPS), and an increase of high density lipoprotein cholesterol (HDL-C) levels; (2) a decrease of inflammatory cytokines such as interleukin 1 beta (IL-1β), interleukin 4 (IL-4), interleukin 6 (IL-6), interleukin 10 (IL-10), tumor necrosis factor alpha (TNF-α), and interferon gamma (INF-γ); (3) a decrease the reactive oxygen species (ROS) level in liver tissue; and (4) alleviation of pathological injuries of liver, epididymis, and small intestinal tissues caused by NAFLD and protection of body tissues. qPCR and Western blot results showed that RBTP could up-regulate the mRNA and protein expressions of LPL, PPAR-α, CYP7A1, and CPT1, and down-regulate PPAR-γ and C/EBP-α in the liver of NAFLD mice. In addition, RBTP up-regulated the expression of occludin and ZO-1, and down-regulated the expression of CD36 and TNF-α in the small intestines of NAFLD mice. Studies on mice feces showed that RBTP reduced the level of Firmicutes and increased the minimum levels of Bacteroides and Akkermansia, as well as reduced the proportion of Firmicutes/Bacteroides in the feces of NAFLD mice, which play a role in regulating intestinal microecology. Component analysis showed that RBTP contained seven polyphenolic compounds: Gallic acid, (-)-epigallocatechin, catechin, L-epicatechin, (-)-epigallocatechin gallate, (-)-gallocatechin gallate, and (-)-epicatechin gallate (ECG), and high levels of caffeine, (-)-epigallocatechin (EGC), and ECG. RBTP improved the intestinal environment of NAFLD mice with the contained active ingredients, thus playing a role in preventing NAFLD. The effect was positively correlated with the dose of 100 mg/kg, which was even better than that of the clinical drug bezafibrate.

“…PPAR is a member of the nuclear receptor superfamily that regulates the expression of target genes, and can be activated by ligands such as fatty acid-like compounds. PPAR plays important roles during cell signal transduction processes, and is involved in a wide variety of metabolic pathways such as oxidative respiration and fatty acid β-oxidation, as well as the physiological and pathological processes of various diseases, including obesity [36]. There are three types of PPARs: α, β, and γ. PPAR-γ is highly expressed in adipose tissues, and regulates the processes of adipocyte proliferation and differentiation.…”

Sichuan pickle is a traditional fermented food in China which is produced by the spontaneous fermentation of Chinese cabbage. In this study, the anti-obesity effects of a new lactic acid bacterium (Lactobacillus fermentum CQPC05, LF-CQPC05) isolated from Sichuan pickles were assessed in vivo. An obese animal model was established in mice by inducing obesity with high-fat diet. Both serum and tissues were collected from the mice, and then subjected to qPCR and Western blot analyses. The results showed that LF-CQPC05 could decrease the values of hepatosomatic, epididymal fat, and perirenal fat indices that were induced by a high-fat diet in mice. Moreover, LF-CQPC05 reduced the levels of alanine aminotransferase (ALT), aspartate aminotransaminase (AST), total cholesterol (TC), triglyceride (TG), and low-density lipoprotein cholesterol (LDL-C), and increased the level of high-density lipoprotein cholesterol (HDL-C) in both serum samples and liver tissues of obese mice fed with a high-fat diet. Pathological observations demonstrated that LF-CQPC05 could alleviate the obesity-induced pathological changes in the liver tissue of mice, and reduce the degree of adipocyte enlargement. The results of qPCR and Western blot analyses further indicated that LF-CQPC05 upregulated the mRNA and protein expression levels of lipoprotein lipase (LPL), PPAR-α: peroxisome proliferator-activated receptor-alpha (PPAR-α), (cholesterol 7 alpha-hydroxylase) CYP7A1, and carnitine palmitoyltransferase 1 (CPT1A), and downregulated the expression levels of peroxisome proliferator-activated receptor-gamma (PPAR-γ) and CCAAT enhancer-binding protein alpha (C/EBP-α) in both liver tissue and epididymal adipose tissue. Taken altogether, this study reveals that LF-CQPC05 can effectively inhibit high-fat diet-induced obesity. Its anti-obesity effect is comparable to that of l-carnitine, and is superior to that of Lactobacillus delbrueckii subsp. bulgaricus, a common strain used in the dairy industry. Therefore, LF-CQPC05 is a high-quality microbial strain with probiotic potential.

We determined the lipid-lowering effect of a new strain of the lactic acid bacteria Lactobacillus plantarum CQPC02 (LP-CQPC02), from Sichuan pickled cabbages, using an in vivo animal model. A high-fat diet was used to generate obese mice. The effect of LP-CQPC02 was measured using serum parameters and tissues collected from the mice. Obese mice treated with LP-CQPC02 had a lower organ index for liver, epididymal fat, and perirenal fat, and lower levels of aminotransferase (AST), alanine aminotransferase (ALT), triglyceride (TG), and total cholesterol (TC), and low density lipoprotein cholesterol (LDL-C) but higher levels of high density lipoprotein cholesterol (HDL-C) in the serum and liver. LP-CQPC02-treated obese mice also had lower serum levels of the cytokines tumor necrosis factor alpha (TNF-α), interferon gamma (IFN-γ), interleukin 6 (IL-6), and interleukin 1 beta (IL-1β), and higher levels of interleukin 4 (IL-4) and interleukin 10 (IL-10). LP-CQPC02 treatment lessened the obesity-associated pathological changes in the liver and epididymal adipose tissue and reduced adipocyte enlargement. The quantitative PCR (qPCR) and Western blot results showed that LP-CQPC02 treatment up-regulated mRNA and protein expression of lipoprotein lipase (LPL), peroxisome proliferator-activated receptor-alpha (PPAR-α), cholesterol 7 alpha-hydroxylase (CYP7A1), and carnitine palmitoyltransferase 1 (CPT1), but down-regulated peroxisome proliferator-activated receptor-gamma (PPAR-γ) and CCAAT enhancer-binding protein alpha (C/EBP-α) expression in the liver and epididymal adipose tissue. LP-CQPC02 effectively inhibited high-fat diet-induced obesity. The effects of LP-CQPC02 are comparable to the drug l-carnitine but superior to Lactobacillus delbruechii subsp. bulgaricus (LDSB), which is commonly used in the dairy industry. LP-CQPC02 is a potentially useful, high-quality probiotic strain.
