The determinants of metabolic and reproductive health disorders in the peripartum period and the degree to which feeding and lying space and management can influence health are only partially understood. The objective of this randomized controlled study was to determine whether providing noncompetitive feeding and lying access in the close-up dry period improves health and immune function. Forty-eight Holstein cows of all parities were randomly assigned to a treatment group of 6 to 10 cows in 1 pen with either 80% cows to stalls and 90 cm of feeding space per cow (understocked) or 120% stocking density and 45 cm of feeding space per cow (overstocked) for 3 wk before expected calving...

Organic anion-transporting polypeptides (OATPs; gene symbol SLCO) are membrane transporters that mediate the transport of wide ranges of compounds. Expression of different OATP members has been reported in the kidney, liver, placenta, brain, and intestine. Due to their broad substrate spectra and wide distribution within human body, these transporters have been proposed to play key roles in the influx transport of many oral drugs. Inflammation is known to regulate the expression and functions of many drug-metabolizing enzymes and drug transporters...

PURPOSE: Trabectedin is one of the few active agents in soft tissue sarcoma (STS) but hepatotoxicity is frequent and represents a dose-limiting factor. Protective strategies aiming at counteracting this important side effect have a crucial clinical impact. Due to its antioxidant properties, N-acetylcysteine (NAC) has a recognized hepatoprotective effect and this provides the rationale for testing NAC in the management of trabectedin-induced hepatotoxicity. METHODS: Patients with recurrent or metastatic soft tissue sarcoma, consecutively observed at our institution, who were considered eligible to trabectedin, received concomitant NAC if they had impaired hepatic or renal function at baseline or developed hepatotoxicity during treatment...

Sirt6 is one of the sirtuin family members, a kind of NAD+-dependent histone deacetylase and ADP-ribose transferase enzyme. It has an important role in physiological and pathological processes, regulating aging, cancer, obesity, insulin resistance, inflammation, and energy metabolism. Recent studies have suggested that reduced Sirt6 action is related to obesity and diabetes. Aging and overnutrition, two major risk factors for obesity and diabetes, lead to decreased Sirt6 level and function, which results in abnormal glucose and lipid metabolism...

Accumulating evidence highlights the fact that long non‑coding RNAs (lncRNAs) serve as critical factors in the growth of hepatocellular carcinoma (HCC). The dysregulation of lncRNA KCNQ1 opposite strand/antisense transcript 1 (KCNQ1OT1) has been reported in numerous human benign diseases. However, the role of KCNQ1OT1 in human HCC remains poorly understood. In this study, we demonstrated that the expression of KCNQ1OT1 was abnormally increased in HCC tissues. The ectopic high expression of KCNQ1OT1 was associated with liver cirrhosis, a larger tumor size, an advanced TNM stage, and a worse overall survival and tumor‑free survival...

Hepatic gluconeogenesis is essential to maintain the blood glucose levels, and its abnormal activation leads to hyperglycemia and type 2 diabetes. However, the molecular mechanisms in the regulation of hepatic gluconeogenesis remain to be fully defined. In this study, using murine hepatocytes and a liver-specific knockout mouse model, we explored the physiological role of nuclear factor Y (NF-Y) in regulating hepatic glucose metabolism and the underlying mechanism. We found that NF-Y targets the gluconeogenesis pathway in the liver...

In this work, the in vivo biocompatibility and biodegradation behavior of Mg-Nd-Zn-Zr alloy (denoted as JDBM) screws were studied using a goat femoral condyle fracture model. Blood analysis indicates that the liver and kidney functions of goats were not affected by JDBM, JDBM coated with brushite (denoted as JDBM-DCPD) and PLA implants. Radiographic analysis shows that JDBM-DCPD screw has lower degradation rate than JDBM. Histological images show that compared with PLA, JDBM and JDBM-DCPD show superior effect to promote more new bone formation...

AIMS: Heme oxygenase-1 (HO-1), an endogenous cytoprotective enzyme, is reported that can be localized in mitochondria under stress, contributing to preserve mitochondrial function. Mitochondrial quality control (QC) is essential to cellular health and recovery linked with redox homeostasis. Recent studies reported that phosphoglycerate mutase family member (PGAM) 5, a mitochondria-resident phosphatase, plays critical role in mitochondrial homeostasis. Therefore, we aim to investigate cytoprotective mechanisms of HO-1 in I/R-induced hepatic injury focusing on mitochondrial QC associated with PGAM5 signaling...

BACKGROUND: The advent of human-induced pluripotent stem cells holds great promise for producing ample individualized hepatocytes. Although previous efforts have succeeded in generating hepatocytes from human pluripotent stem cells in vitro by viral-based expression of transcription factors and/or addition of growth factors during the differentiation process, the safety issue of viral transduction and high cost of cytokines would hinder the downstream applications. Recently, the use of small molecules has emerged as a powerful tool to induce cell fate transition for their superior stability, safety, cell permeability, and cost-effectiveness...

Hepatic encephalopathy (HE) is a neuropsychiatric complication commonly associated with liver disease, namely cirrhosis. The inability of the liver to metabolize ammonia results in a buildup of ammonia, which can cross the blood-brain barrier and cause significant neurocognitive impairment. Up to 80% of patients with cirrhosis will experience HE and a large proportion of these patients are at high risk of recurrent HE. There are several factors to consider when developing a cost-effective approach to managing HE, such as patient compliance, the adverse event (AE) profile of drug therapy, efficacy of drug therapy, and relative cost-benefits of drug therapy...

Cancer stem cells (CSCs) niche in the tumor microenvironment is responsible for cancer recurrence and therapy failure. To better understand its molecular and biological involvement in hepatocellular carcinoma (HCC) progression, one can design more effective therapies and tailored then to individual patients. While sorafenib is currently the only approved drug for first-line treatment of advanced stage HCC, its role in modulating the CSC niche is estimated to be small. By contrast, transforming growth factor (TGF)-β pathway seems to influence the CSC and thus may impact hallmarks of HCC, such as liver fibrosis, cirrhosis, and tumor progression...

Most individuals adjust their caffeine intake according to the objective and subjective effects induced by the methylxanthine. However, to reach the desired effects, the quantity of caffeine consumed varies largely among individuals. It has been known for decades that the metabolism, clearance, and pharmacokinetics of caffeine is affected by many factors such as age, sex and hormones, liver disease, obesity, smoking, and diet. Caffeine also interacts with many medications. All these factors will be reviewed in the present document and discussed in light of the most recent data concerning the genetic variability affecting caffeine levels and effects at the pharmacokinetic and pharmacodynamic levels that both critically drive the level of caffeine consumption...

BACKGROUND: The cytokine interleukin-18 was originally identified as an interferon-γ-inducing proinflammatory factor; however, there is increasing evidence to suggest that it has non-immunological effects on physiological functions. We previously investigated the potential pathophysiological relationship between interleukin-18 and dyslipidemia, non-alcoholic fatty liver disease, and non-alcoholic steatohepatitis, and suggested interleukin-18 as a possible novel treatment for not only these diseases but also for cancer immunotherapy...

Primary hepatocyte culture is an important in vitro system for the study of liver functions. In vivo , hepatocytes have high oxidative metabolism. However, oxygen supply by means of diffusion in in vitro static cultures is much less than that by blood circulation in vivo . Therefore, we investigated whether hypoxia contributes to dedifferentiation and deregulated metabolism in cultured hepatocytes. To this end, murine hepatocytes were cultured under static or shaken (60 revolutions per minute) conditions in a collagen sandwich...
