Stem cells and cancer cells express a common subset of antigens called oncofetal antigens. Theoretically, vaccination with stem cells is effective at boosting the preexisting anticancer immune response. Herein we describe the efficacy of two stem cell-based vaccines in the prophylaxis and treatment of subcutaneous hepatic tumors transplanted into mice. C57BL/6j mice were vaccinated weekly with either hepatic stem cells (HSCs) or embryonic stem cells (ESCs) for three weeks, followed by a subcutaneous challenge with Hepa 1-6 cells at one week (group 1) or four weeks (group 2) after vaccination...

Amar Bahadur Singh, Jingwen Liu
Peroxisome proliferator-activated receptor δ (PPARδ) regulates many genes involved in lipid metabolism. Hepatic lysophosphatidylcholine acyltransferase 3 (LPCAT3) has critical functions in triglycerides transport and ER stress response due to its unique ability to catalyze the incorporation of polyunsaturated fatty acids into phospholipids. Previous studies identified liver X receptor as the transcription factor controlling LPCAT3 expression in mouse liver tissue. Here we show that the hepatic LPCAT3 gene is transcriptionally regulated by PPARδ...

BACKGROUND: Guidelines recommend that patients with hepatitis C virus (HCV)-related liver disease be treated for HCV before liver transplant (LT) to eliminate the virus prior to surgery. However, the unpredictability of donor organ availability may limit treatment duration. Interruption of HCV treatment with resumption post-LT is one potential solution which has not been investigated widely. METHODS: Patients from 5 clinical centres included in the large, national, noninterventional Hepa-C registry who started treatment with direct-acting antiviral agents (DAAs) while awaiting LT were identified retrospectively and followed up prospectively...

Historically, the routine use of laboratory automation solutions has been prohibitively expensive for many laboratories. As legacy hardware has begun to emerge on the secondary market, automation is becoming an increasingly affordable option to augment workflow in virtually any laboratory. To assess the utility of legacy liquid handling in stem cell differentiation, a used liquid handling robot was purchased at auction to automate a stem cell differentiation protocol that gives rise to CD14 + CD45+ mononuclear cells...

Acinetobacter baumannii had emerged as an important nosocomial and opportunistic pathogen worldwide. To assess the evolution of colistin resistance in A. baumannii and its effect on bacterial fitness, we exposed five independent colonies of A. baumannii ATCC 17978 to increasing concentrations of colistin in agar (4/5) and liquid media (1/5). Stable resistant isolates were analyzed using whole genome sequencing. All strains were colistin resistant after exposure to colistin. In addition to the previously reported lpxCAD and pmrAB mutations, we identified four novel putative colistin resistance genes: A1S_1983...

Aerosol or inhalational studies of high-consequence pathogens have recently been increasing in number due to the perceived threat of intentional aerosol releases or unexpected natural aerosol transmission. Specific laboratories designed to perform these experiments require tremendous engineering controls to provide a safe and secure working environment and constant systems maintenance to sustain functionality. Class III biosafety cabinets, also referred to as gloveboxes, are gas-tight enclosures with non-opening windows...

Elevated levels of circulating asymmetric and symmetric dimethylarginines (ADMA and SDMA) predict and potentially contribute to end organ damage in cardiovascular diseases. Alanine-glyoxylate aminotransferase 2 (AGXT2) regulates systemic levels of ADMA and SDMA, and also of beta-aminoisobutyric acid (BAIB)-a modulator of lipid metabolism. We identified a putative binding site for hepatic nuclear factor 4 α (HNF4α) in AGXT2 promoter sequence. In a luciferase reporter assay we found a 75% decrease in activity of Agxt2 core promoter after disruption of the HNF4α binding site...

BACKGROUND: Heterochromatin protein 1 (HP1, homologue HepA in Penicillium oxalicum) binding is associated with a highly compact chromatin state accompanied by gene silencing or repression. HP1 loss leads to the derepression of gene expression. We investigated HepA roles in regulating cellulolytic enzyme gene expression, as an increasingly number of studies have suggested that cellulolytic enzyme gene expression is not only regulated by transcription factors, but is also affected by the chromatin status...

JC-001 is a Chinese medicine that has been used to treat liver disease; however, its significance in cancer treatment has not been characterized. In this study, we used an immunocompetent tumor model to characterize the antitumor activity of JC-001. A total of 48 Hepa 1-6 tumor-bearing C57BL/6 mice were randomly grouped into 4 groups and treated with H2O or JC-001 via oral administration. After hepatoma cell lines, including HepG2, Hep3B, SK-Hep-1, and Hepa 1-6, underwent 96 hours of JC-001 treatment, a low cytotoxic effect was observed...

Phosphatidylcholine (PC) is a major phospholipid of mitochondria, comprising 40-50% of both the outer and the inner membranes. However, PC must be imported from its production organelles because mitochondria lack the enzymes essential for PC biosynthesis. In a previous study, we found that StarD7 mediates the intracellular transfer of PC to mitochondria. Therefore, in this study, we analyzed the contribution of StarD7 to the maintenance of mitochondrial phospholipid content and function using siRNA-mediated knockdown and knock-out (KO) of the StarD7 gene in HEPA-1 cells...

Alterations in mitochondrial DNA (mtDNA) and autophagy activation are common events in tumors. Here we have investigated the effect of mitochondrial genome depletion on chemical hypoxia-induced autophagy in liver tumor cells. Human SK-Hep-1 wild-type and mtDNA-depleted (Rho) cells were exposed to the hypoxia mimetic agents CoCl2 and deferoxamine (DFO). Up-regulation of HIF-1α, but not HIF-2α was observed. The expression of several HIF-1α target genes was also found. In human SK-Hep-1 and mouse Hepa 1-6 liver tumor cells, but not in the counterpart Rho derived lines, chemical hypoxia increased the abundance of autophagosomes and autolysosomes...

Inhalation of nitric oxide (NO) produces selective pulmonary vasodilation without dilating the systemic circulation. However, the current NO/N2 cylinder delivery system is cumbersome and expensive. We developed a lightweight, portable, and economical device to generate NO from air by pulsed electrical discharge. The objective of this study was to investigate and optimize the purity and safety of NO generated by this device. By using low temperature streamer discharges in the plasma generator, we produced therapeutic levels of NO with very low levels of nitrogen dioxide (NO2) and ozone...

This study investigates the impacts of outdoor and indoor ozone concentrations, ESP operation and occupancy on particle number concentrations within a modern office in Changsha, China. The office's one-pass air handling system contains a mini-bag filter (MERV 12) followed by an electrostatic precipitator (ESP) and high efficiency particulate air (HEPA) filter. Over a five-week period the system was operated either without the ESP (Stage 1, first-third week) or with the ESP (Stage 2, fourth and fifth week). Ozone and particle number concentrations were measured on working days...

Significant strides have been made in optimizing the design of filtration and pressurization systems used on the enclosed cabs of mobile mining equipment to reduce respirable dust and provide the best air quality to the equipment operators. Considering all of the advances made in this area, one aspect that still needed to be evaluated was a comparison of the efficiencies of the different filters used in these systems. As high-efficiency particulate arrestance (HEPA) filters provide the highest filtering efficiency, the general assumption would be that they would also provide the greatest level of protection to workers...
