Abstract
Liver disease is a common and serious threat to human health. The progression of liver diseases is influenced by many physiologic processes, including oxidative stress, inflammation, bile acid metabolism, and autophagy. Various factors lead to the dysfunction of these processes and basing on the different pathogeny, pathology, clinical manifestation, and pathogenesis, liver diseases are grouped into different categories. Specifically, Sirtuin1 (SIRT1), a member of the sirtuin protein family, has been extensively studied in the context of liver injury in recent years and are confirmed the significant role in liver disease. SIRT1 has been found to play a critical role in regulating key processes in liver injury. Further, SIRT1 seems to cause divers outcomes in different types of liver diseases. Recent studies have showed some therapeutic strategies involving modulating SIRT1, which may bring a novel therapeutic target. To elucidate the mechanisms underlying the role of sirtuin1 in liver injury and its potentiality as a therapeutic target, this review outlines the key signaling pathways associated with sirtuin1 and liver injury, and discusses recent advances in therapeutic strategies targeting sirtuin1 in liver diseases.

Abstract
Alcohol-associated liver disease (ALD) is a substantial cause of morbidity and mortality worldwide and represents a spectrum of liver injury beginning with hepatic steatosis (fatty liver) progressing to inflammation and culminating in cirrhosis. Multiple factors contribute to ALD progression and disease severity. Here, we overview several crucial mechanisms related to ALD end-stage outcome development, such as epigenetic changes, cell death, hemolysis, hepatic stellate cells activation, and hepatic fatty acid binding protein 4. Additionally, in this review, we also present two clinically relevant models using human precision-cut liver slices and hepatic organoids to examine ALD pathogenesis and progression.

Abstract
Liver cancer is a severe concern for public health officials since the clinical cases are increasing each year, with an estimated 5-year survival rate of 30%–35% after diagnosis. Hepatocellular carcinoma (HCC) constitutes a significant subtype of liver cancer (approximate75%) and is considered primary liver cancer. Treatment for liver cancer mainly depends on the stage of its progression, where surgery including, hepatectomy and liver transplantation, and ablation and radiotherapy are the prime choice. For advanced liver cancer, various drugs and immunotherapy are used as first-line treatment, whereas second-line treatment includes chemotherapeutic drugs from natural and synthetic origins. Sorafenib and lenvatinib are first-line therapies, while regorafenib and ramucirumab are second-line therapy. Various metabolic and signaling pathways such as Notch, JAK/ STAT, Hippo, TGF-β, and Wnt have played a critical role during HCC progression. Dysbiosis has also been implicated in liver cancer. Drug-induced toxicity is a key obstacle in the treatment of liver cancer, necessitating the development of effective and safe medications, with natural compounds such as resveratrol, curcumin, diallyl sulfide, and others emerging as promising anticancer agents. This review highlights the current status of liver cancer research, signaling pathways, therapeutic targets, current treatment strategies and the chemopreventive role of various natural products in managing liver cancer.

Abstract
Hepatocellular carcinoma (HCC) is among the most common and lethal form of cancer worldwide. However, its diagnosis and treatment are still dissatisfactory, due to limitations in the understanding of its pathogenic mechanism. Therefore, it is important to elucidate the molecular mechanisms and identify novel therapeutic targets for HCC. Circadian rhythm-related genes control a variety of biological processes. These genes play pivotal roles in the initiation and progression of HCC and are potential diagnostic markers and therapeutic targets. This review gives an update on the research progress of circadian rhythms, their effects on the initiation, progression, and prognosis of HCC, in a bid to provide new insights for the research and treatment of HCC.

Abstract
TREM1 and TREM2 are members of the triggering receptors expressed on myeloid cells (TREM) family. Both TREM1 and TREM2 are immunoglobulin superfamily receptors. Their main function is to identify foreign antigens and toxic substances, thereby adjusting the inflammatory response. In the liver, TREM1 and TREM2 are expressed on non-parenchymal cells, such as liver sinusoidal endothelial cells, Kupffer cells, and hepatic stellate cells, and cells which infiltrate the liver in response to injury including monocyte-derived macrophages and neutrophils. The function of TREM1 and TREM2 in inflammatory response depends on Toll-like receptor 4. TREM1 mainly augments inflammation during acute inflammation, while TREM2 mainly inhibits chronic inflammation to protect the liver from pathological changes. Chronic inflammation often induces metabolic abnormalities, fibrosis, and tumorigenesis. The above physiological changes lead to liver-related diseases, such as liver injury, nonalcoholic steatohepatitis, hepatic fibrosis, and hepatocellular carcinoma. Here, we review the function of TREM1 and TREM2 in different liver diseases based on inflammation, providing a more comprehensive perspective for the treatment of liver-related diseases.

Abstract
Fatty liver disease (hepatosteatosis) is a hallmark of ALD and NAFLD. FABP4 is normally expressed in adipocytes and macrophages. ALD leads to FABP4 synthesis/release from steatotic hepatocytes. FABP4 stimulates hepatoma cell growth and migration.
Fatty liver disease (hepatosteatosis) is a common early pathology in alcohol-dependent and obese patients. Fatty acid binding protein-4 (FABP4) is normally expressed in adipocytes and macrophages and functions as a regulator of intracellular lipid movement/storage. This study sought to investigate hepatic FABP4 expression and function in alcoholic liver disease (ALD) and hepatocellular carcinoma (HCC). Using chronic ethanol fed mouse models and patient samples FABP4 expression was analyzed. Human HCC cells, and HCC cells transfected to express CYP2E1, were exposed to ethanol and analyzed for FABP4 expression, or exposed to rhFABP4 (in the absence/presence of ERK, p38-MAPK or JNK1/2 inhibitors) and cell proliferation and migration measured. Hepatosteatotic-ALD mouse models exhibited increased hepatic FABP4 mRNA and protein levels, with FABP4 expression confirmed in hepatocytes. In HCC cells, CYP2E1-dependent ethanol metabolism induced FABP4 expression in vitro and exogenous rhFABP4 stimulated proliferation and migration, effects abrogated by ERK and JNK1/2 inhibition. Increased FABP4 was also detected in ALD/ALD-HCC patients, but not patients with viral hepatitis/HCC. Collectively these data demonstrate ethanol metabolism induces hepatic FABP4 expression and FABP4 promotes hepatoma cell proliferation/migration. These data suggest liver-derived FABP4 may be an important paracrine-endocrine factor during hepatic foci expansion and/or hepatoma progression in the underlying setting of ALD.

Abstract
Alcohol‑associated hepatocellular carcinoma (HCC) is a subtype of HCC with poor prognosis. The present study aimed to identify key biomarkers for alcohol‑associated HCC. The gene data profiles and corresponding clinical traits of patients with alcohol‑associated HCC were downloaded from The Cancer Genome Atlas (TCGA) database. Firstly, good genes and good samples were identified, which were subsequently used to conduct weighted gene co‑expression network analysis (WGCNA). Hub genes in the significant modules were selected following Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses, and from constructing a protein‑protein interaction (PPI) network. Real hub genes among hub genes were determined following progression, survival analysis and gene set enrichment analysis (GSEA), as well as reverse transcription‑quantitative PCR and immunohistochemical staining of non‑alcohol‑ and alcohol‑associated HCC samples. In total, 64 good samples of alcohol‑associated HCC with height score <160 were selected, from which 15,195 good genes were identified and used to conduct WGCNA; 8 gene co‑expressed modules were identified using WGCNA, while 3 modules (including pink, magenta and turquoise) were significantly associated with Child‑Pugh score, T‑stage and body weight. Following GO and KEGG analysis and construction of the PPI network, a total of 30 hub genes were identified in the aforementioned 3 gene co‑expressed modules, while 16 hub genes (including AURKB, BUB1, BUB1B, CCNB1, CCNB2, CDC20, CDCA8, CDK1, PLK1, RPS5, RPS7, RPS8, RPS14, RPS27, RPSA and TOP2A) were associated with the development of alcohol‑associated HCC, and had a significant prognosis value. Among these genes, only RPS8 was highly expressed in alcohol‑associated HCC, but not in non‑alcohol‑associated HCC, while RPS5 was not significantly associated in either alcohol‑ or non‑alcohol‑associated HCC. GSEA demonstrated that 10 pathways, including RNA polymerase and ribosome pathways were enriched in alcohol‑associated HCC samples where RPS8 was highly expressed. Taken together, the results of the present study demonstrate that RPS8 may be a novel biomarker for the diagnosis of patients with alcohol‑associated HCC.

Abstract
Background Several studies demonstrated that glioblastoma multiforme progression and recurrence is linked to epigenetic regulatory mechanisms. Sirtuin 1 (SIRT1) plays an important role in glioma progression, invasion, and treatment response and is a potential therapeutic target. The aim of this study is to test the feasibility of 2-[18F]BzAHA for quantitative imaging of SIRT1 expression–activity and monitoring pharmacologic inhibition in a rat model of intracerebral glioma. Methods Sprague Dawley rats bearing 9L (N = 12) intracerebral gliomas were injected with 2-[18F]BzAHA (300–500 µCi/animal i.v.) and dynamic positron-emission tomography (PET) imaging was performed for 60 min. Then, SIRT1 expression in 9L tumors (N = 6) was studied by immunofluorescence microscopy (IF). Two days later, rats with 9L gliomas were treated either with SIRT1 specific inhibitor EX-527 (5 mg/kg, i.p.; N = 3) or with histone deacetylases class IIa specific inhibitor MC1568 (30 mg/kg, i.p.; N = 3) and 30 min later were injected i.v. with 2-[18F]BzAHA. PET-computerized tomography-magnetic resonance (PET/CT/MR) images acquired after EX-527 and MC1568 treatments were co-registered with baseline images. Results Standard uptake values (SUVs) of 2-[18F]BzAHA in 9L tumors measured at 20 min post-radiotracer administration were 1.11 ± 0.058 and had a tumor-to-brainstem SUV ratio of 2.73 ± 0.141. IF of 9L gliomas revealed heterogeneous upregulation of SIRT1, especially in hypoxic and peri-necrotic regions. Significant reduction in 2-[18F]BzAHA SUV and distribution volume in 9L tumors was observed after administration of EX-527, but not MC1568. Conclusions PET/CT/MRI with 2-[18F]BzAHA can facilitate studies to elucidate the roles of SIRT1 in gliomagenesis and progression, as well as to optimize therapeutic doses of novel SIRT1 inhibitors.

Abstract
Better understanding of the molecular mechanism involved in hepatocellular carcinoma (HCC) progression is essential for the development of therapeutic strategies to overcome chemoresistance in HCC patients. In this work, we show that 6-phosphogluconate dehydrogenase (6PGD), a key enzyme of the oxidative pentose phosphate pathway, is important for HCC growth and survival. Compared to normal liver tissues, we demonstrate that 6PGD expression is upregulated in HCC tissues. 6PGD overexpression increases 6PGD activity and promotes growth in normal liver cells. In contrast, targeting 6PGD using both genetic and pharmacological approaches inhibits HCC growth and survival. Combination of chemotherapeutic agents with 6PGD inhibition achieves greater efficacy in inhibiting HCC growth and survival than chemotherapeutic agent alone. We further show that inhibition of 6PGD activates AMP-activated protein kinase (AMPK) and acetyl-coenzyme A carboxylase 1 (ACC1), and decreases level of NADPH/NAD + and NADH in HCC, leading to SIRT1 activity reduction and oxidative stress. Conversely, AMPK depletion significantly abolishes the effects of physcion (a selective small-molecule 6PGD inhibitor) in decreasing NADPH/NAD + ratio, growth and survival, confirming the role of AMPK as the relevant upstream activator with 6PGD inhibition in HCC cells. Our work is the first to demonstrate the upregulation of 6PGD and its critical involvement in growth and survival in HCC. Our findings suggest 6PGD as a promising therapeutic target to overcome chemoresistance in HCC.

Abstract
Stem cells drive embryonic and fetal development. In several adult tissues, they retain the ability to self-renew and differentiate into a variety of specialized cells, thus contributing to tissue homeostasis and repair throughout life span. Alcohol consumption is associated with an increased risk for several diseases and conditions. Growing and developing tissues are particularly vulnerable to alcohol's influence, suggesting that stem- and progenitor-cell function could be affected. Accordingly, recent studies have revealed the possible relevance of alcohol exposure in impairing stem-cell properties, consequently affecting organ development and injury response in different tissues. Here, we review the main studies describing the effects of alcohol on different types of progenitor/stem cells including neuronal, hepatic, intestinal and adventitial progenitor cells, bone-marrow-derived stromal cell, dental pulp, embryonic and hematopoietic stem cells, and tumor-initiating cells. A better understanding of the nature of the cellular damage induced by chronic and episodic heavy (binge) drinking is critical for the improvement of current therapeutic strategies designed to treat patients suffering from alcohol-related disorders.

Abstract
Alcoholic liver disease is the result of cascade events, which clinically first lead to alcoholic fatty liver, and then mostly via alcoholic steatohepatitis or alcoholic hepatitis potentially to cirrhosis and hepatocellular carcinoma. Pathogenetic events are linked to the metabolism of ethanol and acetaldehyde as its first oxidation product generated via hepatic alcohol dehydrogenase (ADH) and the microsomal ethanol-oxidizing system (MEOS), which depends on cytochrome P450 2E1 (CYP 2E1), and is inducible by chronic alcohol use. MEOS induction accelerates the metabolism of ethanol to acetaldehyde that facilitates organ injury including the liver, and it produces via CYP 2E1 many reactive oxygen species (ROS) such as ethoxy radical, hydroxyethyl radical, acetyl radical, singlet radical, superoxide radical, hydrogen peroxide, hydroxyl radical, alkoxyl radical, and peroxyl radical. These attack hepatocytes, Kupffer cells, stellate cells, and liver sinusoidal endothelial cells, and their signaling mediators such as interleukins, interferons, and growth factors, help to initiate liver injury including fibrosis and cirrhosis in susceptible individuals with specific risk factors. Through CYP 2E1-dependent ROS, more evidence is emerging that alcohol generates lipid peroxides and modifies the intestinal microbiome, thereby stimulating actions of endotoxins produced by intestinal bacteria; lipid peroxides and endotoxins are potential causes that are involved in alcoholic liver injury. Alcohol modifies SIRT1 (Sirtuin-1; derived from Silent mating type Information Regulation) and SIRT2, and most importantly, the innate and adapted immune systems, which may explain the individual differences of injury susceptibility. Metabolic pathways are also influenced by circadian rhythms, specific conditions known from living organisms including plants. Open for discussion is a 5-hit working hypothesis, attempting to define key elements involved in injury progression. In essence, although abundant biochemical mechanisms are proposed for the initiation and perpetuation of liver injury, patients with an alcohol problem benefit from permanent alcohol abstinence alone.

Abstract
SIRT1 is a NAD-dependent histone deacetylase that is important in a wide variety of physiological and pathophysiological processes. Although many studies have examined the relationship between SIRT1 and cancer, the role of SIRT1 in tumor malignancy is controversial. Here, we examined the effects of the SIRT1 activator CAY10591 in gingival epithelial carcinoma Ca9-22 cells. CAY10591 treatment dose- and time-dependently increased SIRT1 level and activity. The treatment decreased cell growth and induced cell-cycle repressor p21 levels. In addition, dimethyl sulfoxide significantly reduced cellular invasion and migration, and CAY10591 enhanced this decrease. Quantitative PCR analysis showed that CAY10591 decreased expression of several invasion/migration promoter genes and induced repressor genes. Our findings suggest that CAY10591 suppresses cell growth and invasion/migration activity in gingival squamous cell carcinoma Ca9-22 cells.

Abstract
Background Nicotinamide riboside (NR) is a nicotinamide adenine dinucleotide (NAD+) precursor which is present in foods such as milk and beer. It was reported that NR can prevent obesity, increase longevity, and promote liver regeneration. However, whether NR can prevent ethanol-induced liver injuries is not known. This study aimed to explore the effect of NR on ethanol induced liver injuries and the underlying mechanisms. Methods We fed C57BL/6 J mice with Lieber-DeCarli ethanol liquid diet with or without 400 mg/kg·bw NR for 16 days. Liver injuries and SirT1-PGC-1α-mitochondrial function were analyzed. In in vitro experiments, HepG2 cells (CYP2E1 over-expressing cells) were incubated with ethanol ± 0.5 mmol/L NR. Lipid accumulation and mitochondrial function were compared. SirT1 knockdown in HepG2 cells were further applied to confirm the role of SirT1 in the protection of NR on lipid accumulation. Results We found that ethanol significantly decreased the expression and activity of hepatic SirT1 and induced abnormal expression of enzymes of lipid metabolism in mice. Both in vivo and in vitro experiments showed that NR activated SirT1 through increasing NAD+ levels, decreased oxidative stress, increased deacetylation of PGC-1α and mitochondrial function. In SirT1 knockdown HepG2 cells, NR lost its ability in enhancing mitochondrial function, and its protection against lipid accumulation induced by ethanol. Conclusions NR can protect against ethanol induced liver injuries via replenishing NAD+, reducing oxidative stress, and activating SirT1-PGC-1α-mitochondrial biosynthesis. Our data indicate that SirT1 plays an important role in the protection of NR against lipid accumulation and mitochondrial dysfunctions induced by ethanol. NR could reverse ethanol induced hepatic steatosis and oxidative stress. Boosting NAD+, NR enhanced mitochondrial functions by regulating SirT1/ PGC-1α. SirT1 played an important role in NR's protection against alcohol liver injuries.

Abstract
Heavy use of alcohol can lead to addictive behaviors and to eventual alcohol-related tissue damage. While increased consumption of alcohol has been attributed to various factors including level of alcohol exposure and environmental factors such as stress, data from behavioral scientists and physiological researchers are revealing roles for the circadian rhythm in mediating the development of behaviors associated with alcohol use disorder as well as the tissue damage that drives physiological disease. In this work, we compile recent work on the complex mutually influential relationship that exists between the core circadian rhythm and the pharmacodynamics of alcohol. As we do so, we highlight implications of the relationship between alcohol and common circadian mechanisms of effected organs on alcohol consumption, metabolism, toxicity, and pathology.

Abstract
SCOPE Resveratrol has been shown to improve insulin resistance via activating the NAD+ -dependent deacetylase SIRT1, but the effects of resveratrol on ethanol-induced insulin resistance remain unclear. This study was designed to explore the potential mechanism by which resveratrol ameliorated ethanol-induced insulin resistance, focusing on its regulations on the ratio of NAD+ /NADH and SIRT1 expression. METHODS AND RESULTS Male Sprague-Dawley rats were fed either control or ethanol liquid diets containing 0.8, 1.6 and 2.4 g/kg·bw ethanol with or without 100 mg/kg·bw resveratrol for 22 weeks. Resveratrol improved ethanol (2.4 g/kg·bw) induced reductions in insulin sensitivity, SIRT1 expression (51%, P < 0.05), NAD+ /NADH ratio (196%, P < 0.01) as well as the expression and activity of ALDH2 while decreased the augmentations in the expression and activity of ADH and CYP2E1. In primary rat hepatocytes, ethanol exposure (25 mmol/L, 24 h) similarly decreased SIRT1 expression and NAD+ /NADH ratio (33%, P < 0.05; 32%, P < 0.01), and 0.1 μmol/L resveratrol treatment reversed these decreases and inhibited the expressions of ADH and CYP2E1. CONCLUSION Resveratrol exhibits benefits against ethanol-induced insulin resistance via improving the ratio of NAD+ /NADH to regulate SIRT1, which is associated with the modulation of ethanol metabolism enzymes.

Abstract
BACKGROUND Spleen-deficiency syndrome (SDS) in Traditional Chinese Medicine (TCM) played pivotal roles on the development of hepatocellular carcinoma (HCC). This study was performed to establish and evaluate HCC model in mice with SDS in TCM. MATERIAL AND METHODS A total of 90 C57BL/6 mice were randomized in six groups (n=15 for each group): A, Control group; B, SDS group; C, orthotopic HCC (OHCC) group; D, OHCC based on SDS (SDS-OHCC) group; E, Drug-induced HCC (DHCC) group; F, DHCC based on SDS (SDS-DHCC) group. The SDS model were established by subcutaneous injection of reserpine, followed by the OHCC or DHCC model establishment. The SDS scores, tumor formation rate and survival time were recorded and calculated, as well as the histochemical stain was performed. RESULTS The SDS scores of mice in Group B, D, F were 17.57±4.86 (P<0.05 vs. Group A), 18.13±4.53 (P<0.05 vs. Group A and C) and 23.32±4.94 (P<0.05 vs. Group A and E) respectively. The tumor formation rate of mice in Group C, D, E and F were 73.33%, 100%, 60% and 80% respectively. The survival time of mice in Group C, D, E and F were 26.42±5.27, 17.33±4.76 (P<0.05 vs. Group C), 35.77±6.12 and 22.61±5.05 (P<0.05 vs. Group E) respectively. CONCLUSION The SDS-oriented HCC mice models were simple and easily-operated models for further studies on SDS oriented tumor. Meanwhile, SDS was a pivotal factor for low outcome of hepatic tumor.

Abstract
Evidence from recent researchers suggested that RTN4 is a multifunctional gene, including tumor suppression, apoptosis, vascular remodeling, and inhibition of axonal regeneration. The CAA and TATC insertion/deletion polymorphisms (CAA/TATC polymorphisms) of RTN4 3″-untranslated regions (UTRs) have been linked to cervical squamous cell carcinoma (CSCC), uterine leiomyomas (UL) and non-small cell lung cancer (NSCLC). However, the association between these two polymorphisms sites with Hepatocellular Carcinoma (HCC) risk was not carry out before. A total of 284 HCC patients and 484 control subjects were recruited for this study. The RTN4 CAA/TATC insertion/deletion genotypes were determined using polymerase chain reaction (PCR) assay. The ID/DD genotypes of CAA were significantly associated with an increased risk of HCC compared with the II genotype (ID vs. II: OR = 1.50, 95% CI: 1.10-2.04; DD vs. II: OR = 2.00, 95%CI: 1.15-3.46). Meanwhile, the frequency of D allele of CAA was significantly related with an increased risk of HCC compared with the I allele (D vs. I: OR = 1.39, 95% CI: 1.12-1.73). The ID genotypes of TATC was significantly associated with an increased risk of HCC compared with the DD genotype (ID vs. DD: OR = 1.70, 95% CI: 1.23-2.33). The present study provided evidence that RTN4 CAA/TATC polymorphisms were associated with HCC development in Chinese Han population.

Abstract
Hepatocellular carcinoma (HCC) is a significant cause of cancer-related morbidity and mortality. Chronic, heavy ethanol consumption is a major risk for developing the worsening liver pathologies that culminate in hepatic cirrhosis, the leading risk factor for developing HCC. A significant body of work reports the biochemical and pathological consequences of ethanol consumption and metabolism during hepatocarcinogeneis. The systemic effects of ethanol means organ system interactions are equally important in understanding the initiation and progression of HCC within the alcoholic liver. This review aims to summarize the effects of ethanol-ethanol metabolism during the pathogenesis of alcoholic liver disease, the progression toward HCC and the importance of ethanol as a comorbid factor for HCC development.

Abstract
The present review spans a broad spectrum of topics dealing with alcoholic liver disease (ALD), including clinical research, translational research, pathogenesis and therapies. A special accent is placed on alcohol misuse, as alcohol is a legally commercialized and taxable product. Drinking alcohol, particularly from a young age, is a major health problem. Alcoholism is known to contribute to morbidity and mortality. A systematic literature search was performed in order to obtain updated data (2008-2015). The review is focused on genetic polymorphisms of alcohol metabolizing enzymes and the role of cytochrome p450 2E1 and iron in ALD. Alcohol-mediated hepatocarcinogenesis is also discussed in the presence or absence of co-morbidities such as viral hepatitis C as well as therapeutic the role of innate immunity in ALD-HCV. Moreover, emphasis was placed on alcohol and drug interactions, as well as liver transplantation for end-stage ALD. Finally, the time came to eradicate alcohol-induced liver and intestinal damage by using betaine.

Abstract
Elevated levels of serum saturated fatty acid palmitate have been shown to promote insulin resistance, increase cellular ROS production, and trigger cell apoptosis in hepatocytes during the development of obesity. However, it remains unclear whether palmitate directly impacts the circadian clock in hepatocytes, which coordinates nutritional inputs and hormonal signaling with downstream metabolic outputs. Here we presented evidence that the molecular clock is a novel target of palmitate in hepatocytes. Palmitate exposure at low dose inhibits the molecular clock activity and suppresses the cyclic expression of circadian targets including Dbp, Nr1d1 and Per2 in hepatocytes. Palmitate treatment does not seem to alter localization or reduce protein expression of BMAL1 and CLOCK, the two core components of the molecular clock in hepatocytes. Instead, palmitate destabilizes the protein-protein interaction between BMAL1-CLOCK in a dose and time-dependent manner. Furthermore, we showed that SIRT1 activators could reverse the inhibitory action of palmitate on BMAL1-CLOCK interaction and the clock gene expression, whereas inhibitors of NAD synthesis mimic the palmitate effects on the clock function. In summary, our findings demonstrated that palmitate inhibits the clock function by suppressing SIRT1 function in hepatocytes.
