Abstract
The liver performs a multitude of bodily functions, whilst retaining the ability to regenerate damaged tissue. In this review, we discuss sex steroid biology, regulation of mammalian liver physiology and the development of new model systems to improve our understanding of liver biology in health and disease. A major risk factor for the development of liver disease is hepatic fibrosis. Key drivers of this process are metabolic dysfunction and pathologic activation of the immune system. Although non-alcoholic fatty liver disease (NAFLD) is largely regarded as benign, it does progress to non-alcoholic steatohepatitis in a subset of patients, increasing their risk of developing cirrhosis and hepatocellular carcinoma. NAFLD susceptibility varies across the population, with obesity and insulin resistance playing a strong role in the disease development. Additionally, sex and age have been identified as important risk factors. In addition to the regulation of liver biochemistry, sex hormones also regulate the immune system, with sexual dimorphism described for both innate and adaptive immune responses. Therefore, sex differences in liver metabolism, immunity and their interplay are important factors to consider when designing, studying and developing therapeutic strategies to treat human liver disease. The purpose of this review is to provide the reader with a general overview of sex steroid biology and their regulation of mammalian liver physiology.

Abstract
Mesenchymal stem cells (MSCs) have multi-lineage differentiation potential which make them an excellent source for cell-based therapies. Histone modification is one of the major epigenetic regulations that play central role in stem cell differentiation. Keeping in view their ability to maintain gene expression essential for successful differentiation, it was interesting to examine the effects of valproic acid (VPA), a histone deacetylase inhibitor, in the hepatic differentiation of MSCs within the 3D scaffold. MSCs were treated with the optimized concentration of VPA in the 3D collagen scaffold. Analyses of hepatic differentiation potential of treated MSCs were performed by qPCR, immunostaining and periodic acid Schiff assay. Our results demonstrate that MSCs differentiate into hepatic-like cells when treated with 5 mM VPA for 24 h. The VPA-treated MSCs have shown significant upregulation in the expression of hepatic genes, CK-18 (P < 0.05), TAT (P < 0.01), and AFP (P < 0.001), and hepatic proteins, AFP (P < 0.05) and ALB (P < 0.01). In addition, acetylation of histones (H3 and H4) was significantly increased (P < 0.001) in VPA-pretreated cells. Further analysis showed that VPA treatment significantly enhanced (P < 0.01) glycogen storage, an important functional aspect of hepatic cells. The present study revealed the effectiveness of VPA in hepatic differentiation within the 3D collagen scaffold. These hepatic-like cells may have an extended clinical applicability in future for successful liver regeneration.

Intravenous indocyanine green dye is insufficient for robust immune cell labelling in the human retina. PLoS One 2020; 15:e0226311.

Abstract
It is not currently possible to reliably visualise and track immune cells in the human central nervous system or eye. Previous work demonstrated that indocyanine green (ICG) dye could label immune cells and be imaged after a delay during disease in the mouse retina. We report a pilot study investigating if ICG can similarly label immune cells within the human retina. Twelve adult participants receiving ICG angiography as part of routine standard of care were recruited. Baseline retinal images were obtained prior to ICG administration then repeated over a period ranging from 2 hours to 9 days. Matched peripheral blood samples were obtained to examine systemic immune cell labelling and activation from ICG by flow cytometry with human macrophage cultures as positive controls. Differences between the delayed near infrared ICG imaging and 488 nm autofluorescence was observed across pathologies, likely arising from the retinal pigment epithelium (RPE). Only one subject demonstrated ICG signal on peripheral blood myeloid cells and only three distinct cell-sized signals appeared over time within the retina of three participants. No significant increase in immune cell activation markers were detected after ICG administration. ICG accumulated in the endosomes of macrophage cultures and was detectable above a minimum concentration, suggesting cell labelling is possible. ICG can label RPE and may be used as an additional biomarker for RPE health across a range of retinal disorders. Standard clinical doses of intravenous ICG do not lead to robust immune cell labelling in human blood or retina and further optimisation in dose and route are required.

Genes Dis 2020; 8:509-520. [PMID: 34179313 PMCID: PMC8209308 DOI: 10.1016/j.gendis.2019.12.012] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2019] [Revised: 12/10/2019] [Accepted: 12/31/2019] [Indexed: 02/07/2023] Open
Abstract
As a potential chemo-therapeutic agent, all-trans retinoic acid (ATRA) can significantly reverse epithelial-mesenchymal transition (EMT) of hepal-6 hepatocarcinoma cell line in vitro, but the mechanism is unclear. The expression profile of microRNA-200 (miR-200) families is different in hepatocellular carcinoma. In this study, we found that ATRA treatment could up-regulate the expression of miR-200a-3p, 200c-3p, and 141-3p, which were involved in ATRA regulated proliferation and apoptosis of hepal-6 cell, but not colony formation. Meanwhile, miR-200a-3p, 200c-3p, and 141-3p could recovery ATRA inhibited migration and invasion abilities of hepal-6 cells at various levels. miR-200a-3p and 200c-3p prevented ATRA from inducing the differentiation and hepatic functions of hepal-6 cells. Antagomir specific for miR-200a-3p and 200c-3p down-regulated the expression of CK18, but only miR-200a-3p antagomir played prominent role in regulating the expression of these mesenchymal markers, N-Cadherin, Snail and Twist. The transcriptional activities of 8 transcription factors were up-regulated and 35 transcription factors were down-regulated by ATRA. Compared with ATRA group, inhibition of miR-200a-3p, 200c-3p, and 141-3p significantly strengthened the expression of Fra1/Jun (AP1), Ets1/PEA3, Brn3, and Zeb1/AREB6 at varying degrees. Therefore, this result suggested that ATRA may suppress EMT through down-regulating miR-200a-3p, 200c-3p and 141-3p related transcription factors. miR-200 and their downstream genes might be the potentially specific targets for the treatment of hepatocarcinoma.

Abstract
Hepatic progenitor cells (HPCs) are potential seed cells for hepatocyte transplantation treatment of liver diseases. ATRA can induce the differentiation and mature function of hepatic progenitor cells, but the mechanism is still poorly understood. Here, by using microRNA array to analyze the expression profiles of microRNA (miR), we found that miR-200 family molecules in HPCs were upregulated after ATRA treatment, especially miR-200a-3p, 200c-3p, and 141-3p. ATRA induction could downregulate the expression of hepatic stem markers Oct4 and AFP, and improve the expression of hepatic markers ALB, CK18, and TAT, and the activity of ALB-GLuc, as well as indocyanine green uptake and glycogen storage function of HPCs. These above effects of ATRA on HPC differentiation were almost inhibited by blocking of miR-200a-3p, but not miR-200c-3p and 141-3p using antagomir. Cell autophagy is associated with ATRA regulation in HPCs, compared with control group, the expression of LC3 and Beclin1 increased in ATRA-treated HPCs, and orange and red fluorescent spot, which represents autophagy flow, also enhanced after ATRA treatment. However, ATRA-induced cell autophagy level was inhibited in antagomir-200a-3p+ATRA-treated cells. Therefore, the present study indicates that antagomir-200a-3p is related to ATRA-induced hepatic differentiation of HPCs through regulating cell autophagy, supporting the possible use of ATRA as a key inducer in HPC-based therapy of liver diseases.

Abstract
Reliable animal models are required for the in vivo study of the molecular mechanisms and effects of chemotherapeutic drugs in hepatocarcinoma. In vivo tracing techniques based on firefly luciferase (FLuc) may optimize the non-invasive monitoring of experimental animals. The present study established a murine Hepa1-6-FLuc cell line that stably expressed a retrovirus-delivered FLuc protein gene. The cell morphology, proliferation, migration and invasion ability of Hepa1-6-FLuc cells were the same as that of the Hepa1-6 cells, and thus is suitable to replace Hepa1-6 cells in the construction of hepatocarcinoma animal models. No differences in subcutaneous tumor mass and its pathomorphology from implanted Hepa1-6-FLuc cells were observed compared with Hepa1-6 control tumors. Bioluminescence imaging indicated that the Luc signal of the Hepa1-6-FLuc cells was consistently strengthened with increases in tumor mass; however, the Luc signal of Hepa1-6-AdFLuc became weaker and eventually disappeared during tumor development. Therefore, compared with the transient expression by adenovirus, stable expression of the FLuc gene in Hepa1-6 cells may better reflect cell proliferation and survival in vivo, and provide a reliable source for the establishment of hepatocarcinoma models.

Abstract
Developing a thorough understanding of experimental methods of hepatic differentiation in hepatic progenitor cells (HPCs) should expand the knowledge of hepatocyte induction in vitro and may help to develop cell transplantation therapies for the clinical usage of HPCs in liver diseases. A previous induction method effectively induced differentiation and metabolic abilities in HPCs. Periodic acid-Schiff (PAS) staining is used to identify glycogen synthesis and hepatocyte function; however, this method failed to detect induced hepatocytes. The present study aimed to investigate the possible factors affecting the previous confusing results of PAS staining. Removal of single induction factors, including dexamethasone, hepatic growth factor and fibroblast growth factor 4 from the induction media did not restore PAS staining, whereas replacement of 2% horse serum (HS) with 10% fetal bovine serum (FBS) significantly increased the number of PAS positive cells. Following 12 days of basal induction, replacing the induction medium with media containing 10% FBS for 12–72 h significantly improved PAS staining, but did not influence indocyanine green uptake. Furthermore, incubation in induction medium with 10% FBS following 12 days of normal induction did not affect the expression of hepatic markers and mature function of HPCs. Therefore, the present study suggested that 2% HS in the induction medium did not affect the hepatic function of induced cells, but did affect glycogen storage, whereas replacement of medium with 10% FBS in advance of PAS staining may restore the failure of PAS staining in low serum concentrations of induced hepatocytes.

Combinational use of lipid-based reagents for efficient transfection of primary fibroblasts and hepatoblasts. Biotechniques 2017; 63:37-39.

Abstract
Commercially available lipid-based transfection reagents are widely used to deliver DNA to cells. However, these lipid-based transfection reagents show poor gene transfer efficiency in primary cells. Here, we demonstrate a simple method to improve gene transfer efficiency in primary fibroblasts and hepatoblasts using a combination of lipid-based transfection reagents. Our data show that combined use of Lipofectamine LTX and FuGENE HD increases the efficiency of gene transfer compared with the use of either reagent alone, and this combination achieves the best result of any pairwise combination of Lipofectamine LTX, FuGENE HD, TransFectin, and Fibroblast Transfection Reagent.

Abstract
BACKGROUND AND AIM In view of its unique properties of detoxification and involvement of metabolic and biochemical functions, in vitro hepatocyte culture serves as a valuable material for drug screening and mechanistic analysis for pathology of liver diseases. The restriction of rapid de-differentiation and inaccessibility of human hepatocytes from routine clinical procedure, however, limits its use. METHODS To address this issue, the effort to direct human mesenchymal stem cells (hMSCs) into hepatocytes using a modified protocol was proposed. With the additional treatment of histone deacetylase inhibitor (HDACi) and DNA methyltransferase inhibitor (DNMTi), in vitro hMSC-derived hepatocytes were cultivated and their hepatic characteristics were examined. RESULTS By using a modified protocol, it was shown that Trichostatin A and 5-aza-2-deoxycitidine protected differentiating cells from death and could sufficiently trigger a wide range of liver-specific markers as well as liver functions including albumin production, glycogen storage, and urea cycle in hMSC-derived hepatocytes. The increased mRNA expression for hepatitis C virus (HCV) entry including CD81, Occludin, LDL receptor, and scavenger receptor class B type I in hMSC-derived hepatocytes was also detected, implying its potential to be utilized as an in vitro model to analyze dynamic HCV infection. CONCLUSIONS The present study successfully established a protocol to direct hMSCs into hepatocyte-like cells suggesting the beneficial impact to apply HDACi and DNMTi as potent modulators for hMSCs to liver differentiation.

Abstract
We describe a near infrared (NIR) light-activated gene silencing method in undifferentiated human embryonic stem cell (hESC) using a plasmonic hollow gold nanoshell (HGN) as the siRNA carrier. Our modular biotin-streptavidin coupling strategy enables positively charged TAT-peptide to coat oligonucleotides-saturated nanoparticles as a stable colloid formation. TAT-peptide coated nanoparticles with dense siRNA loading show efficient penetration into a wide variety of hESC cell lines. The siRNA is freed from the nanoparticles and delivered to the cytosol by femtosecond pulses of NIR light with potentially exquisite spatial and temporal control. The effectiveness of this approach is shown by targeting GFP and Oct4 genes in undifferentiated hESC (H9). The accelerated expression of differentiation markers for all three germ layers resulting from Oct4 knockdown confirms that this method has no detectable adverse effects that limit the range of differentiation. This biocompatible and NIR laser-activated patterning method makes possible single cell resolution of siRNA delivery for diverse studies in stem cell biology, tissue engineering and regenerative medicine.

Abstract
5-azacytidine (5-azaC) is known to induce cardiomyocyte differentiation. However, its function in hepatocyte differentiation is unclear. The present study investigated the in vitro capability of 5-azaC to promote maturation and differentiation of mouse embryonic hepatic progenitor cells, with the aim of developing an approach for improving hepatic differentiation. Mouse embryonic hepatic progenitor cells (HP14.5 cells) were treated with 5-azaC at concentrations from 0 to 20 μmol/l, in addition to hepatocyte induction culture medium. Hepatocyte induction medium induces HP14.5 cell differentiation. 5-azaC may enhance the albumin promotor-driven Gaussia luciferase (ALB-GLuc) activity in induced HP14.5 cells. In the present study 2 μmol/l was found to be the optimum concentration with which to achieve this. The expression of hepatocyte-associated factors was not significantly different between the group treated with 5-azaC alone and the control group. The mRNA levels of ALB; cytokeratin 18 (CK18); tyrosine aminotransferase (TAT); and cytochrome p450, family 1, member A1 (CYP1A1); in addition to the protein levels of ALB, CK18 and uridine diphosphate glucuronyltransferase 1A (UGT1A) in the induced group with 5-azaC, were higher than those in the induced group without 5-azaC, although no significant differences were detected in expression of the hepatic stem cell markers, DLK and α-fetoprotein, between the two groups. Treatment with 5-azaC alone did not affect glycogen synthesis or indocyanine green (ICG) metabolic function in HP14.5 cells, although it significantly increased ICG uptake and periodic acid-Schiff-positive cell numbers amongst HP14.5 cells. Therefore, the present study demonstrated that treatment with 5-azaC alone exerted no effects on the maturation and differentiation of HP14.5 cells. However, 5-azaC exhibited a synergistic effect on the terminal differentiation of induced hepatic progenitor cells in association with a hepatic induction medium.

Abstract
Primary hepatocytes are highly differentiated cells and proliferatively quiescent. However, the stress produced during liver digestion seems to activate cell cycle entry by proliferative/dedifferentiation programs that still remain unclear. The aim of this work was to assess whether the oxidative stress associated with hepatocyte isolation affects cell cycle and particularly cytokinesis, the final step of mitosis. Hepatocytes were isolated from C57BL/6 mice by collagenase perfusion in the absence and presence of N-acetyl cysteine (NAC). Polyploidy, cell cycle, and reactive oxygen species (ROS) were studied by flow cytometry (DNA, phospho-histone 3, and CellROX(®) Deep Red) and Western blotting (cyclins B1 and D1, and proliferating cell nuclear antigen). mRNA expression of cyclins A1, B1, B2, D1, and F by reverse transcription (RT)-PCR was also assessed. Glutathione levels were measured by mass spectrometry. Here we show that hepatocyte isolation enhanced cell cycle entry, increased hepatocyte binucleation, and caused marked glutathione oxidation. Addition of 5 mM NAC to the hepatocyte isolation media prevented glutathione depletion, partially blocked ROS production and cell cycle entry of hepatocytes, and avoided the blockade of mitosis progression, abrogating defective cytokinesis and diminishing the formation of binucleated hepatocytes during isolation. Therefore, addition of NAC to the isolation media decreased the generation of polyploid hepatocytes confirming that oxidative stress occurs during hepatocyte isolation and it is responsible, at least in part, for cytokinesis failure and hepatocyte binucleation.
