Life Sci 2021; 287:120119. [PMID: 34743004 DOI: 10.1016/j.lfs.2021.120119] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2021] [Revised: 10/29/2021] [Accepted: 11/01/2021] [Indexed: 12/26/2022]
Abstract
AIM Hepatic fibrosis in injured liver is characterized by the activation of hepatic stellate cells (HSCs) from their quiescent state. Survivin (BIRC5) is one of the key genes that are upregulated during activation of HSCs but their role in HSC activation and fibrosis progression is unknown. Here, we have investigated the role of survivin protein in early fibrogenic activation of HSCs and fibrosis progression in chronic liver injury. MATERIALS & METHODS Primary quiescent HSCs were isolated from healthy mice liver through perfusion and cultured for fibrogenic activation. Survivin expression was suppressed by its pharmacological suppressant, YM155. We developed chronic liver injury induced fibrotic mice model through administrating repeated dose of CCl4 for 2 weeks and 4 weeks. Mice were pre-treated with YM155 a week before CCl4 administration till 2nd week of dosing and then discontinued. Hepatic parameters were characterized and underlying mechanisms were investigated. KEY FINDINGS Survivin expression gradually increased along with the expression of αSMA, collagen I activation maker in HSCs during their activation from quiescent state. Survivin suppression through YM155 downregulated αSMA, collagen I. Pre-treatment of YM155 in mice ceased the early activation of HSCs and onset of fibrosis in injured liver. However, discontinuation of YM155 initiated the activation of HSCs and fibrosis progression that shows survivin expression in HSCs is essential for their early activation and onset of liver fibrosis. SIGNIFICANCE Survivin expression induces with activation of HSCs and drives onset of liver fibrosis in injured liver. Targeting survivin protein in activated HSCs could be a potential anti-fibrotic therapeutic approach in chronic liver injury.

Abstract
More than 70% of eukaryotic proteins are regulated by phosphorylation. However, the mechanism of dephosphorylation that counteracts phosphorylation is less studied. Phosphatases are classified into 104 distinct groups based on substrate-specific features and the sequence homologies in their catalytic domains. Among them, dual-specificity phosphatases (DUSPs) that dephosphorylate both phosphoserine/threonine and phosphotyrosine are important for cellular homeostasis. Ssu72 is a newly studied phosphatase with dual specificity that can dephosphorylate both phosphoserine/threonine and phosphotyrosine. It is important for cell-growth signaling, metabolism, and immune activation. Ssu72 was initially identified as a phosphatase for the Ser5 and Ser7 residues of the C-terminal domain of RNA polymerase II. It prefers the cis configuration of the serine-proline motif within its substrate and regulates Pin1, different from other phosphatases. It has recently been reported that Ssu72 can regulate sister chromatid cohesion and the separation of duplicated chromosomes during the cell cycle. Furthermore, Ssu72 appears to be involved in the regulation of T cell receptor signaling, telomere regulation, and even hepatocyte homeostasis in response to a variety of stress and damage signals. In this review, we aim to summarize various functions of the Ssu72 phosphatase, their implications in diseases, and potential therapeutic indications.

Abstract
The liver possesses a remarkable regenerative capacity based partly on the ability of hepatocytes to re-enter the cell cycle and divide to replace damaged cells. This capability is substantially reduced upon chronic damage, but it is not clear if this is a cause or consequence of liver disease. Here, we investigate whether blocking hepatocyte division using two different mouse models affects physiology as well as clinical liver manifestations like fibrosis and inflammation. We find that in P14 Cdk1Liv-/- mice, where the division of hepatocytes is abolished, polyploidy, DNA damage, and increased p53 signaling are prevalent. Cdk1Liv-/- mice display classical markers of liver damage two weeks after birth, including elevated ALT, ALP, and bilirubin levels, despite the lack of exogenous liver injury. Inflammation was further studied using cytokine arrays, unveiling elevated levels of CCL2, TIMP1, CXCL10, and IL1-Rn in Cdk1Liv-/- liver, which resulted in increased numbers of monocytes. Ablation of CDK2-dependent DNA re-replication and polyploidy in Cdk1Liv-/- mice reversed most of these phenotypes. Overall, our data indicate that blocking hepatocyte division induces biological processes driving the onset of the disease phenotype. It suggests that the decrease in hepatocyte division observed in liver disease may not only be a consequence of fibrosis and inflammation, but also a pathological cue.

Abstract
The liver is a highly regenerative organ, but its regenerative capacity is compromised in severe liver diseases. Hepatocyte-driven liver regeneration that involves the proliferation of preexisting hepatocytes is a primary regeneration mode. On the other hand, liver progenitor cell (LPC)-driven liver regeneration that involves dedifferentiation of biliary epithelial cells or hepatocytes into LPCs, LPC proliferation, and subsequent differentiation of LPCs into hepatocytes is a secondary mode. This secondary mode plays a significant role in liver regeneration when the primary mode does not effectively work, as observed in severe liver injury settings. Thus, promoting LPC-driven liver regeneration may be clinically beneficial to patients with severe liver diseases. In this review, we describe the current understanding of LPC-driven liver regeneration by exploring current knowledge on the activation, origin, and roles of LPCs during regeneration. We also describe animal models used to study LPC-driven liver regeneration, given their potential to further deepen our understanding of the regeneration process. This understanding will eventually contribute to developing strategies to promote LPC-driven liver regeneration in patients with severe liver diseases.

Abstract
This study aimed to determine the role of survivin in sepsis patients.Serum samples of 288 sepsis patients and 290 healthy individuals (as healthy controls) were collected 24 hours within enrollment. Serum survivin and inflammatory cytokines were detected by enzyme-linked immunosorbent assay, and biochemical indexes were recorded. In sepsis patients, acute pathologic and chronic health evaluation II score and sequential organ failure assessment score were evaluated, and 28-day mortality was recorded.Survivin was greatly decreased in sepsis patients compared to healthy controls (P < .001) and it predicted decreased sepsis risk (area under curve (AUC): 0.921, 95% confidence interval (CI): 0.900-0.942). For clinical characteristics of sepsis patients, survivin was negatively correlated with acute pathologic and chronic health evaluation II score (P < .001), score and sequential organ failure assessment score (P < .001), serum creatinine (P < .001), white blood cell (P = .037), C-reactive protein (P < .001), tumor necrosis factor-α (P < .001), interleukin (IL)-1β (P < .001), IL-6 (P < .001), and IL-8 (P < .001), while positively correlated with albumin (P < .001). For prognosis of sepsis patients, survivin was decreased in deaths compared to survivors (P < .001), and it predicted decreased death risk (AUC: 0.625, 95% CI: 0.558-0.692). Meanwhile, accumulating mortality was decreased in survivin high patients compared to survivin low patients (P = .006). However, multivariate logistic regression revealed survivin was not an independent predictive factor for 28-day mortality, indicating it might interact with other independent factors to affect prognosis of sepsis patients.Survivin was decreased in sepsis patients and predicted decreased sepsis risk. Meanwhile, survivin was correlated with declined inflammation, reduced disease severity, and favorable prognosis in sepsis patients.

Abstract
Polyploidy (or whole-genome duplication) is the condition of having more than two basic sets of chromosomes. Polyploidization is well tolerated in many species and can lead to specific biological functions. In mammals, programmed polyploidization takes place during development in certain tissues, such as the heart and placenta, and is considered a feature of differentiation. However, unscheduled polyploidization can cause genomic instability and has been observed in pathological conditions, such as cancer. Polyploidy of the liver parenchyma was first described more than 100 years ago. The liver is one of the few mammalian organs that display changes in polyploidy during homeostasis, regeneration and in response to damage. In the human liver, approximately 30% of hepatocytes are polyploid. The polyploidy of hepatocytes results from both nuclear polyploidy (an increase in the amount of DNA per nucleus) and cellular polyploidy (an increase in the number of nuclei per cell). In this Review, we discuss the regulation of polyploidy in liver development and pathophysiology. We also provide an overview of current knowledge about the mechanisms of hepatocyte polyploidization, its biological importance and the fate of polyploid hepatocytes during liver tumorigenesis.

Abstract
Myeloid derived suppressor cells (MDSC) in the liver microenvironment protects against the inflammation-induced liver injury in fulminant hepatitis (FH). However, the molecular mechanism through which MDSC is recruited into the inflamed liver remain elusive. Here we identified a protein kinase Tpl2 as a critical mediator of MDSC recruitment into liver during the pathogenesis of Propionibacterium acnes/LPS-induced FH. Loss of Tpl2 dramatically suppressed MDSC mobilization into liver, leading to exaggerated local inflammation and increased FH-induced mortality. Mechanistically, although the protective effect of Tpl2 for FH-induced mortality was dependent on the presence of MDSC, Tpl2 neither directly targeted myeloid cells nor T cells to regulate FH pathogenesis, but functioned in hepatocytes to mediate the induction of MDSC-attracting chemokine CXCL1 and CXCL2 through modulating IL-25 (also known as IL-17E) signaling. As a consequence, increased MDSC in the inflamed liver specifically restrained the local proliferation of infiltrated pathogenic CD4+ T cells, and thus protected against the inflammation-induced acute liver failure. Together, our findings established Tpl2 as a critical mediator of MDSC recruitment and highlighted the therapeutic potential of Tpl2 for the treatment of FH.

Abstract
Polyploid cells contain more than two homologous sets of chromosomes. The original observations of liver polyploidy date back to the 1940s, but functional roles for polyploid cells are still unclear. Liver polyploidy may influence regeneration, stress response, and cancer, although little evidence has established direct causal links between polyploidy and these biological phenotypes. In this review, we will introduce broad concepts about polyploidy including its distribution in nature and how polyploids form in normal and pathological situations. Then we will examine recent discoveries that have begun to clarify functionality and disease relevance of liver polyploidy. Finally, we will discuss implications and future directions of research about polyploidy in the liver.

Abstract
Yaks (Bos grunniens) have special physiological structures that help them adapt to high-altitude environments. Survivin is actively studied in cancer tissues, but less in normal tissues. Therefore, the aim of the present study was to analysis the relationship between survivin expression and apoptosis rate in yaks. A partial gene sequence of survivin was cloned and characterized using bioinformatics. The expression of survivin was investigated using real-time quantitative PCR (RT-qPCR) and western blot (WB) analysis and localized using immunohistochemistry (IHC). The results revealed that in normal physiological organs, survivin is mainly expressed in cytoplasm and its expression was up-regulated with age. Its expression in heart and liver was higher than in other organs, such as spleen, lung, brain, kidney, and testis. It is noteworthy that the expression of survivin in spleen is differed from that in other organs. Therefore, we selected immune organs (lymph node, thymus and spleen) to investigate the relationship between survivin expression and apoptosis. Caspase-3 was used as a reference. Within the same age group, the expression of survivin was the highest in the spleen, but that of caspase-3 was the highest in the lymph node (P < 0.01). Furthermore, the IHC analysis revealed that survivin and caspase-3 are expressed in the same location (mainly in the cytoplasm, Hassall's corpuscles, the medulla of the lymph node, the red pulp and marginal zone of the spleen. More importantly, survivin expression was down-regulated with age in immune organs, and the opposite trend was observed for caspase-3 expression (P < 0.01). The results proved that the expression of survivin and caspase-3 is down- and up-regulated with age, respectively, suggesting that survivin and caspase-3 might coordinating and participating in slowing down the rate of apoptosis rate in immune organs of healthy yak.

Abstract
Nowadays, orthotopic liver transplantation is considered the most efficient approach to the end stage of chronic hepatic cirrhosis. Because of the limitations of orthotopic liver transplantation, stem cells are an attractive therapeutic option. Mesenchymal stem cells (MSCs) especially show promise as an alternative treatment for hepatic cirrhosis in animal models and during clinical trials. Nevertheless, the homing of transplanted MSCs to the liver occurs in limited numbers. Therefore, we review the strategies for enhancing the homing of MSCs, mainly via the delivery routes, optimizing cell culture conditions, stimulating the target sites, and genetic modification.

Abstract
UNLABELLED Obesity is a critical risk factor for hepatocellular carcinoma (HCC). However, it remains unknown whether inhibition of de novo lipid biosynthesis can suppress HCC. In this study, we blocked the sterol regulatory element-binding protein (SREBP) pathway, one of the key determinants of lipid homeostasis, by ablating 78-kDa cell-surface glycoprotein or SREBP cleavage-activating protein in hepatocytes, as well as by administering a chemical compound called betulin. We found that either genetically or pharmacologically inhibiting the SREBP pathway dramatically reduced diethylnitrosamine-induced HCC progression by down-regulating tumor-promoting cytokines, including interleukin (IL)-6, tumor necrosis factor alpha, and IL-1β. CONCLUSION Inhibition of de novo lipid biosynthesis by suppressing the SREBP pathway prevents HCC. This study identifies a previously underappreciated role of the SREBP pathway in HCC and suggests a novel metabolic strategy to control liver cancer. (Hepatology 2017;65:1936-1947).

Abstract
A characteristic cellular feature of the mammalian liver is the progressive polyploidization of the hepatocytes, where individual cells acquire more than two sets of chromosomes. Polyploidization results from cytokinesis failure that takes place progressively during the course of postnatal development. The proportion of polyploidy also increases with the aging process or with cellular stress such as surgical resection, toxic stimulation, metabolic overload, or oxidative damage, to involve as much as 90% of the hepatocytes in mice and 40% in humans. Hepatocyte polyploidization is generally considered an indicator of terminal differentiation and cellular senescence, and related to the dysfunction of insulin and p53/p21 signaling pathways. Interestingly, the high prevalence of hepatocyte polyploidization in the aged mouse liver can be reversed when the senescent hepatocytes are serially transplanted into young mouse livers. Here we review the current knowledge on the mechanism of hepatocytes polyploidization during postnatal growth, aging, and liver diseases. The biologic significance of polyploidization in senescent reversal, within the context of new ways to think of liver aging and liver diseases is considered.

Hepatocellular carcinoma repression by TNFα-mediated synergistic lethal effect of mitosis defect-induced senescence and cell death sensitization. Hepatology 2016; 64:1105-20.

Abstract
UNLABELLED Hepatocellular carcinoma (HCC) is a cancer lacking effective therapies. Several measures have been proposed to treat HCCs, such as senescence induction, mitotic inhibition, and cell death promotion. However, data from other cancers suggest that single use of these approaches may not be effective. Here, by genetic targeting of Survivin, an inhibitor of apoptosis protein (IAP) that plays dual roles in mitosis and cell survival, we identified a tumor necrosis factor alpha (TNFα)-mediated synergistic lethal effect between senescence and apoptosis sensitization in malignant HCCs. Survivin deficiency results in mitosis defect-associated senescence in HCC cells, which triggers local inflammation and increased TNFα. Survivin inactivation also sensitizes HCC cells to TNFα-triggered cell death, which leads to marked HCC regression. Based on these findings, we designed a combination treatment using mitosis inhibitor and proapoptosis compounds. This treatment recapitulates the therapeutic effect of Survivin deletion and effectively eliminates HCCs, thus representing a potential strategy for HCC therapy. CONCLUSION Survivin ablation dramatically suppresses human and mouse HCCs by triggering senescence-associated TNFα and sensitizing HCC cells to TNFα-induced cell death. Combined use of mitotic inhibitor and second mitochondrial-derived activator of caspases mimetic can induce senescence-associated TNFα and enhance TNFα-induced cell death and synergistically eliminate HCC.

Abstract
Borealin, a member of the chromosomal passenger complex, plays a key regulatory role at centromeres and the central spindle during mitosis. Loss of Borealin leads to defective cell proliferation and early embryonic lethality. The in vivo functions of Borealin in mammalian postnatal development, tissue homeostasis, and tumorigenesis remain elusive. We specifically analyzed the role of Borealin in regulating postnatal liver development, damage-induced liver regeneration, and liver carcinogenesis using mice carrying conditional Borealin alleles. Perinatal loss of Borealin caused increased genome ploidy and enlarged cell size in hepatocytes, likely due to the impaired function of the chromosomal passenger complex in mitosis. Borealin deletion also showed attenuated expansion of Sox9+HNF4α+ progenitor-like cells in liver regeneration during 3,5-diethoxycarbonyl-1,4-dihydrocollidine diet-induced liver injury. Moreover, ΔN90-β-Catenin and c-Met-induced hepatocarcinogenesis development was largely impeded by Borealin deletion. These findings indicate that Borealin plays a key role in liver development, regeneration, and tumorigenesis and suggests that Borealin could be a potential target for related liver diseases.

Upregulation of hydroxysteroid sulfotransferase 2B1b promotes hepatic oval cell proliferation by modulating oxysterol-induced LXR activation in a mouse model of liver injury. Arch Toxicol 2016; 91:271-287. [PMID: 27052460 DOI: 10.1007/s00204-016-1693-z] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2015] [Accepted: 03/21/2016] [Indexed: 02/07/2023]
Abstract
Hydroxysteroid sulfotransferase 2B1b (SULT2B1b) sulfates cholesterol and oxysterols. Hepatic oval cells (HOCs), thought to be progenitor cells, can be triggered in chemically injured livers. The present study focused on the role of SULT2B1b in HOC proliferation after liver injury. Our experiments revealed that the expression of SULT2B1b was increased dramatically in a chemical-induced liver injury model, mainly in HOCs. Upon challenge with a hepatotoxic diet containing 0.1 % 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC), SULT2B1-/- mice presented alleviated liver injury and less HOC proliferation compared with wild-type (WT) mice, and these findings were verified by serum analysis, histopathology, immunofluorescence staining, RNA-seq, and Western blotting. HOCs derived from SULT2B1-/- mice showed lower proliferative capability than those from WT mice. SULT2B1b overexpression promoted growth of the WB-F344 hepatic oval cell line, whereas SULT2B1b knockdown inhibited growth of these cells. The IL-6/STAT3 signaling pathway also was promoted by SULT2B1b. Liquid chromatography and mass spectrometry indicated that the levels of 22-hydroxycholesterol, 25-hydroxycholesterol, and 24,25-epoxycholesterol were higher in the DDC-injured livers of SULT2B1-/- mice than in livers of WT mice. The above oxysterols are physiological ligands of liver X receptors (LXRs), and SULT2B1b suppressed oxysterol-induced LXR activation. Additional in vivo and in vitro experiments demonstrated that LXR activation could inhibit HOC proliferation and the IL-6/STAT3 signaling pathway, and these effects could be reversed by SULT2B1b. Our data indicate that upregulation of SULT2B1b might promote HOC proliferation and aggravate liver injury via the suppression of oxysterol-induced LXR activation in chemically induced mouse liver injury.

Abstract
Cirrhosis is defined as the histological development of regenerative nodules surrounded by fibrous bands in response to chronic liver injury. In cirrhotic liver where hepatocytes proliferation is compromised, liver progenitor cells (LPCs) are activated and then differentiated into hepatocytes and cholangiocytes, leading to the generation of regenerative nodules and functional restoration. Here, we summarize and discuss recent findings on the mechanisms underlying LPCs-mediated regeneration in liver cirrhosis. Firstly, we provide recent research on the mechanism underlying LPCs activation in severe or chronic liver injury. Secondly, we present new and exciting data on exploring the origin of LPCs, which reveal that the hepatocytes give rise to duct-like progenitors that then differentiate back into hepatocytes in chronic liver injury or liver cirrhosis. Finally, we highlight recent findings from the literature exploring the role of LPCs niche in directing the behavior and fate of LPCs. This remarkable insight into the cellular and molecular mechanisms of LPCs-mediated regeneration in liver cirrhosis will provide a basis for translating this knowledge into clinical application.

Abstract
The Baculoviral IAP repeat-containing protein 5 (BIRC5), also known as inhibitor of apoptosis protein survivin, is a member of the chromosomal passenger complex and a key player in mitosis. To investigate the function of BIRC5 in liver regeneration, we analyzed a hepatocyte-specific BIRC5-knockout mouse model using a quantitative label-free proteomics approach. Here, we present the analyses of the proteome changes in hepatocyte-specific BIRC5-knockout mice compared to wildtype mice, as well as proteome changes during liver regeneration induced by partial hepatectomy in wildtype mice and mice lacking hepatic BIRC5, respectively. The BIRC5-knockout mice showed an extensive overexpression of proteins related to cellular maintenance, organization and protein synthesis. Key regulators of cell growth, transcription and translation MTOR and STAT1/STAT2 were found to be overexpressed. During liver regeneration proteome changes representing a response to the mitotic stimulus were detected in wildtype mice. Mainly proteins corresponding to proliferation, cell cycle and cytokinesis were up-regulated. The hepatocyte-specific BIRC5-knockout mice showed impaired liver regeneration, which had severe consequences on the proteome level. However, several proteins with function in mitosis were found to be up-regulated upon the proliferative stimulus. Our results show that the E3 ubiquitin-protein ligase UHRF1 is strongly up-regulated during liver regeneration independently of BIRC5.
