Abstract
BACKGROUND Nonalcoholic fatty liver disease (NAFLD), characterized by excessive hepatic lipid accumulation, imposes serious challenges on public health worldwide. Breastfeeding has been reported to reduce the risk of NAFLD. Extracellular vesicles (EVs) are bilayer membrane vesicles released from various cells into the extracellular space, participating in multiple life processes. Whether EVs from human milk exert metabolic benefits against NAFLD is worth investigating. METHODS AND RESULTS In this study, the EVs were isolated from human milk collected from healthy mothers and quantified. Functional analyses were performed using the NAFLD mouse model and free fatty acid (FFA)-stimulated mouse primary hepatocytes. The results showed that human milk-derived EVs could effectively alleviate high fat diet-induced hepatic steatosis and insulin resistance in mice with NAFLD via inhibiting lipogenesis and increasing lipolysis. The FFA-induced lipid accumulation was also inhibited in hepatocytes after treatment with human milk-derived EVs. Mechanistically, the human milk derived-EVs cargo (proteins and miRNAs), which linked to lipid metabolism, may be responsible for these beneficial effects. CONCLUSION The findings of this study highlighted the therapeutic benefits of human milk-derived EVs and provided a new strategy for NAFLD treatment.

Abstract
Obesity is a global epidemic, it can induce glucose and lipid metabolism disorder and non-alcoholic fatty liver disease (NAFLD). This study explored a new way to control weight and improve fatty liver, namely, living in hypoxia environment and supplement with lactoferrin (Lf). Sixty male C57BL/6J mice were divided into six groups, namely, control, hypoxia, high-fat diet, hypoxia + high-fat diet, hypoxia + high-fat diet + low dose Lf intervention, and hypoxia + high-fat diet + high-dose Lf intervention. Mice in the hypoxia treatment groups were treated with approximately 11.5 % oxygen for 6 h every day for 8 weeks. Results showed that interventions combining Lf and hypoxia treatments showed better effect against obesity and NAFLD than hypoxia treatment alone. The interventions controlled weight gain in mice, improved glucolipid metabolism in mice. The combination intervention reduced cholesterol absorption by reducing the level of hydrophobic bile acids, and elevating the level of hydrophilic bile acids. Gut microbiota analysis revealed that the combination intervention considerably elevated short chain fatty acids (SCFAs)-producing bacteria level, and reduced the Desulfovibrionaceae_unclassified level. Thus, Lf combined with hypoxia intervention effectively prevents obesity and NAFLD by restoring gut microbiota composition and bile acid profile.

Abstract
Acute myeloid leukemia (AML) is classified into favorable-risk, intermediate-risk, and poor-risk subtypes. This study aimed to compare the serum proteomic signatures of the three AML subtypes and identify prognostic biomarkers for AML. Serum samples from patients with favorable-risk (n = 14), intermediate-risk (n = 19), and poor-risk AMLs (n = 18) were used for the analysis of tandem mass tag (TMT) labeling-based quantitative proteomics. Comparative analysis was performed to identify differentially expressed proteins (DEPs) between groups. Prognostic proteins were screened using binary logistics regression analysis. TMT-MS/MS proteomics analysis identified 138 DEPs. Fumarate hydratase (FH), isocitrate dehydrogenase 2 (IDH2), and enolase 1 (ENO1) were significantly upregulated in poor-risk patients compared with favorable-risk patients. ELISA assay confirmed that patients with poor-risk AMLs had higher levels of IDH2, ENO1, and FH compared with intermediate-risk AML patients. Logistics analysis identified that proteins 3-hydroxyacyl-CoA dehydrogenase type-2 (HADH, odds ratio (OR) = 1.035, p = 0.010), glutamine synthetase (GLUL, OR = 1.022, p = 0.039), and lactotransferrin (LTF, OR = 1.1224, p = 0.016) were associated with poor prognosis, and proteins ENO1 (OR = 1.154, p = 0.053), FH (OR = 1.043, p = 0.059), and IDH2 (OR = 3.350, p = 0.055) were associated with AML prognosis. This study showed that AML patients had elevated levels of FH, IDH2, ENO1, LTF, and GLUL proteins and might be at high risk of poor prognosis.

Abstract
Bisphenol-A (BPA) and gamma-radiation are two risky environmental pollutants that human beings are exposed to in everyday life and consequently they threaten human health via inducing oxidative stress, inflammation, and eventually tissue damage. This study aims at appraising the protective effect of Boswellic Acid (BA) (250 mg/kg/day, orally) administration on BPA (150 mg/kg/day, i.p) and γ-irradiation (IR) (3 Gy/week for 4 weeks up to cumulative dose of 12 Gy/experimental course) for 4 weeks-induced damage to liver and heart tissues of rats. The present results indicated a significant improvement against damage induced by BPA and IR revealed in biochemical investigations (hepatic PPAR-α/P38 and cardiac ET-1/Calcineurin-A/NFATc1/P38) and histopathological examination of liver and heart. It could be concluded that BA possesses a protective effect against these two deleterious environmental pollutants which attracted major global concerns due to their serious toxicological impact on human health.

Lactoferrin Prevents Hepatic Injury and Fibrosis via the Inhibition of NF-κB Signaling in a Rat Non-Alcoholic Steatohepatitis Model. Nutrients 2021; 14:42.

Abstract
Non-alcoholic steatohepatitis (NASH) can cause liver cirrhosis and hepatocellular carcinoma (HCC), with cases increasing worldwide. To reduce the incidence of liver cirrhosis and HCC, NASH is targeted for the development of treatments, along with viral hepatitis and alcoholic hepatitis. Lactoferrin (LF) has antioxidant, anti-cancer, and anti-inflammatory activities. However, whether LF affects NASH and fibrosis remains unelucidated. We aimed to clarify the chemopreventive effect of LF on NASH progression. We used a NASH model with metabolic syndrome established using connexin 32 (Cx32) dominant negative transgenic (Cx32ΔTg) rats. Cx32ΔTg rats (7 weeks old) were fed a high-fat diet and intraperitoneally injected with dimethylnitrosamine (DMN). Rats were divided into three groups for LF treatment at 0, 100, or 500 mg/kg/day for 17 weeks. Lactoferrin significantly protected steatosis and lobular inflammation in Cx32ΔTg rat livers and attenuated bridging fibrosis or liver cirrhosis induced by DMN. By quantitative RT-PCR, LF significantly down-regulated inflammatory (Tnf-α, Il-6, Il-18, and Il-1β) and fibrosis-related (Tgf-β1, Timp2, and Col1a1) cytokine mRNAs. Phosphorylated nuclear factor (NF)-κB protein decreased in response to LF, while phosphorylated JNK protein was unaffected. These results indicate that LF might act as a chemopreventive agent to prevent hepatic injury, inflammation, and fibrosis in NASH via NF-κB inactivation.

Abstract
Lactoferrin (Lf) can attenuate alcoholic liver injury (ALI) in male mice; however, the effects of Lf on acute ALI in female mice are still unknown. Female C57BL/6J mice were randomly divided into four groups and fed with different diets for 4 weeks: an AIN-93G diet for control (CON) and ethanol (EtOH) groups; an AIN-93G diet with 0.4 and 4% casein replaced by Lf for low-dose Lf (LLf) and high-dose Lf (HLf) groups. Acute ALI was induced by intragastric administration of ethanol (4.8 g/kgbw) every 12 h continuously for three times. HLf had obvious alleviating effects on acute ALI. Lf pretreatment did not affect hepatic alcohol metabolism key enzymes. Meanwhile, the ethanol-induced hepatic reactive oxygen species level increase was not ameliorated by Lf. Metabolomics and bioinformatics analysis results suggested an important role of redox-stress response capacity (RRC). Western blots showed HLf-promoted AKT and AMP-activated protein kinase activations and upregulated Nrf2 and LC3-II expressions, which was associated with RRC improvement. In summary, HLf could prevent acute ALI in female mice, and RRC likely played an important role.

Abstract
Fluorene-9-bisphenol (BHPF), a substitute for bisphenol A (BPA), has been widely used in the synthesis of polyester polymers. Studies have reported multiple BHPF toxicities but its effect on the liver remains unknown. In this study, we performed short-term and subchronic toxicity tests, as well as primary hepatocyte experiments, to investigate the hepatic toxicity of BHPF using CD-1 mice. And microarray was used to analyze the changes of global gene expression in the liver of mice treated with BHPF. The results showed that the liver coefficient and the activities of serum aminotransferases were obviously elevated by BHPF at doses of 27.8 mg/kg body weight (bw)/day or higher in mice treated for 10 days. Histological analysis showed obvious changes, including narrowed hepatic sinuses, dilated central vein, leucocyte infiltration, and cytoplasmic vacuolation, in the livers of mice treated with BHPF at dosages of 2 mg/kg bw/3-day and higher for 36 days. Microarray analyses revealed 2623 differentially expressed genes (DEGs) in the livers of mice treated with 50 mg/kg bw/day of BHPF for 3 days, which could be enriched in GO terms of T cell activation, leukocyte migration, and leukocyte chemotaxis and KEGG pathways of natural killer cell-mediated cytotoxicity and autoimmune thyroid disease. The top 10 hub DEGs, including LTF and MMP8, were observed in the protein-protein interaction network obtained via STRING database analysis, and are proposed as potential biomarkers for liver injury studies. Primary hepatocyte experiments demonstrated the hepatotoxicity of BHPF at concentrations of 10-6 M and higher. This study indicates that BHPF could cause liver injury at relatively low levels, suggesting that the risk of human BHPF exposure should be of concern.

Abstract
Melanocortin 4 receptor (MC4R)-deficient mice had been used for several years to study human nonalcoholic steatohepatitis (NASH). However, although liver pathologic and biochemical indicators have been examined, mice models do not always faithfully display the phenotype of the human disease. In this study, we investigated the MC4R knockout phenotype in miniature pigs. We found that pigs lacking MC4R exhibited hyperorexia, insulin resistance, hyperinsulinemia, disordered lipid metabolism and their livers accumulated significant amounts of fat. We have shown that deletion of MC4R results in hyperphagia and increased body fat, ultimately leading to hepatic steatosis without atherogenic diet.

Abstract
Purpose: Hyperthermia (HT), a clinical treatment involving delivery of heat to tumors, has been used in combination with traditional chemotherapy and radiotherapy to enhance their effects. However, the molecular mechanism underlying the high efficacy of combination therapy is not clear. This study was conducted to identify the molecular mechanism underlying the sensitization of lung cancer to radiotherapy by HT.Materials and methods: Nuclear receptor subfamily 4, group A, member 3 (NR4A3) and Krüppel-like factor 11 (KLF11) expression in non-small-cell lung cancer cells was confirmed by performing real-time quantitative reverse transcription-polymerase chain reaction. Tumor cell proliferation and apoptosis were assessed via a colony-forming assay and Annexin V/propidium iodide staining.Results and conclusions: Expression profile analysis revealed elevated levels of NR4A3 and KLF11 in A549 lung cancer cells after treatment with HT combined with radiation. We also confirmed that NR4A3 and KLF11 induced apoptosis and inhibited cell proliferation by elevating intracellular reactive oxygen species levels. Knockdown of NR4A3 or KLF11 using siRNA led to decreased effects of radiohyperthermia. Finally, the effect of these two factors on lung cancer progression was evaluated by in vivo xenograft studies. Taken together, the results suggest that NR4A3 and KLF11 are critical for increasing the efficacy of radiotherapy in combination with HT.

Abstract
Radiotherapy is a standard treatment option for patients with glioblastoma (GBM). Although it has high therapeutic efficacy, some proportion of the tumor cells that survive after radiotherapy may cause side effects. In this study, we found that fructose 1,6-bisphosphatase 1 (FBP1), a rate-limiting enzyme in gluconeogenesis, was downregulated upon treatment with ionizing radiation (IR). Ets1, which was found to be overexpressed in IR-induced infiltrating GBM, was suggested to be a transcriptional repressor of FBP1. Furthermore, glucose uptake and extracellular acidification rates were increased upon FBP1 downregulation, which indicated an elevated glycolysis level. We found that emodin, an inhibitor of phosphoglycerate mutase 1 derived from natural substances, significantly suppressed the glycolysis rate and IR-induced GBM migration in in vivo orthotopic xenograft mouse models. We propose that the reduced FBP1 level reprogrammed the metabolic state of GBM cells, and thus, FBP1 is a potential therapeutic target regulating GBM metabolism following radiotherapy.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is one of the most common chronic liver diseases with a prevalence of ~25% worldwide. NAFLD includes simple hepatic steatosis, non-alcoholic steatohepatitis, fibrosis, and cirrhosis, which can further progress to hepatocellular carcinoma. Therefore, effective strategies for the prevention of NAFLD are needed. The pathogenesis of NAFLD is complicated due to diverse injury insults, such as fat accumulation, oxidative stress, inflammation, lipotoxicity, and apoptosis, which may act synergistically. Studies have shown that carotenoids, a natural group of isoprenoid pigments, prevent the development of NAFLD by exerting antioxidant, lipid-lowering, anti-inflammatory, anti-fibrotic, and insulin-sensitizing properties. This review summarizes the protective action of carotenoids, with primary focuses on astaxanthin, lycopene, β-carotene, β-cryptoxanthin, lutein, fucoxanthin, and crocetin, against the development and progression of NAFLD.
