Abstract
Chronic liver injury induces liver cirrhosis and facilitates hepatocarcinogenesis. However, the effects of this condition on hepatocyte proliferation and differentiation are unclear. We showed that rodent hepatocytes display a ductular phenotype when they are cultured within a collagenous matrix. This process involves transdifferentiation without the emergence of hepatoblastic features and is at least partially reversible. During the ductular reaction in chronic liver diseases with progressive fibrosis, some hepatocytes, especially those adjacent to ectopic ductules, demonstrate ductular transdifferentiation, but the majority of increased ductules originate from the existing bile ductular system that undergoes extensive remodeling. In chronic injury, hepatocyte proliferation is weak but sustained, and most regenerative nodules in liver cirrhosis are composed of clonally proliferating hepatocytes, suggesting that a small fraction of hepatocytes maintain their proliferative capacity in chronic injury. In mouse hepatocarcinogenesis models, hepatocytes activate the expression of various fetal/neonatal genes, indicating that these cells undergo dedifferentiation. Hepatocyte-specific somatic integration of various oncogenes in mice demonstrated that hepatocytes may be the cells of origin for a broad spectrum of liver tumors through transdifferentiation and dedifferentiation. In conclusion, the phenotypic plasticity and heterogeneity of mature hepatocytes are important for understanding the pathogenesis of chronic liver diseases and liver tumors.

Abstract
Chromatin alterations brought by histone variants and modifications potentially regulate gene transcription from tumor initiation to progression. Histone H3.3 variant is one such epigenetic player important for disease progression and development. Though many studies have implicated H3.3 role in cancer progression and metastasis, its regulation, importance of specific modifications and chaperones have been not understood yet. We report DNA methylation mediated downregulation of histone H3 variant H3.3 in HCC and a concomitant increase in the level of the H3.2 variant. The loss of H3.3 in cancer tissues correlates with a decrease in the histone modifications associated with active transcription like H3K9/K14/K27Ac and H3K4Me3. The ectopic overexpression of H3.3 and H3.2 did not affect global PTMs and cell physiology, probably owing to the deregulation of specific histone chaperones CAF-1 (for H3.2) and HIRA (for H3.3) as observed in HCC tissues. Notably, knockdown of P150, a subunit of CAF-1 leads to a cell cycle arrest in S-phase in a neoplastic rat liver cell line, possibly due to the decrease in the histone levels necessary for DNA packaging. Remarkably, modulation of H3.3 in pre-neoplastic rat liver cells lead to an increase in cell proliferation and a decreased transcription of tumor suppressor genes, recapitulating the tumor cell phenotype. Our data suggests, inhibition of DNA methylation and histone deacetylation leads to the restoration of histone H3 variant expression in tumor cells.

Abstract
Cardiac hypertrophy, characterized by the enlargement of cardiomyocytes, is initially an adaptive response to physiological and pathological stimuli. Decompensated cardiac hypertrophy is related to fibrosis, inflammatory cytokine, maladaptive remodeling, and heart failure. Although pathological myocardial hypertrophy is the main cause of hypertrophy-related morbidity and mortality, our understanding of its mechanism is still poor. Long noncoding RNAs (lncRNAs) are noncoding RNAs that regulate various physiological and pathological processes through multiple molecular mechanisms. Recently, accumulating evidence has indicated that lncRNA-H19 is a potent regulator of the progression of cardiac hypertrophy. For the first time, this review summarizes the current studies about the role of lncRNA-H19 in cardiac hypertrophy, including its pathophysiological processes and underlying pathological mechanism, including calcium regulation, fibrosis, apoptosis, angiogenesis, inflammation, and methylation. The context within which lncRNA-H19 might be developed as a target for cardiac hypertrophy treatment is then discussed to gain better insight into the possible biological functions of lncRNA-H19 in cardiac hypertrophy.

Abstract
BACKGROUND Renal ischemia-reperfusion (I/R) injury is a major cause of AKI. Noncoding RNAs are intricately involved in the pathophysiology of this form of AKI. Transcription of hypoxia-induced, long noncoding RNA H19, which shows high embryonic expression and is silenced in adults, is upregulated in renal I/R injury. METHODS Lentivirus-mediated overexpression, as well as antisense oligonucleotide-based silencing, modulated H19 in vitro. In vivo analyses used constitutive H19 knockout mice. In addition, renal vein injection of adeno-associated virus 2 (AAV2) carrying H19 caused overexpression in the kidney. Expression of H19 in kidney transplant patients with I/R injury was investigated. RESULTS H19 is upregulated in kidney biopsies of patients with AKI, in murine ischemic kidney tissue, and in cultured and ex vivo sorted hypoxic endothelial cells (ECs) and tubular epithelial cells (TECs). Transcription factors hypoxia-inducible factor 1-α, LHX8, and SPI1 activate H19 in ECs and TECs. H19 overexpression promotes angiogenesis in vitro and in vivo. In vivo, transient AAV2-mediated H19 overexpression significantly improved kidney function, reduced apoptosis, and reduced inflammation, as well as preserving capillary density and tubular epithelial integrity. Sponging of miR-30a-5p mediated the effects, which, in turn, led to target regulation of Dll4, ATG5, and Snai1. CONCLUSIONS H19 overexpression confers protection against renal injury by stimulating proangiogenic signaling. H19 overexpression may be a promising future therapeutic option in the treatment of patients with ischemic AKI.

The pro-oncogenic effect of the lncRNA H19 in the development of chronic inflammation-mediated hepatocellular carcinoma. Oncogene 2021; 40:127-139. [PMID: 33093654 DOI: 10.1038/s41388-020-01513-7] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2020] [Revised: 10/01/2020] [Accepted: 10/05/2020] [Indexed: 01/09/2023]
Abstract
The oncofetal long noncoding RNA (lncRNA) H19 is postnatally repressed in most tissues, and re-expressed in many cancers, including hepatocellular carcinoma (HCC). The role of H19 in carcinogenesis is a subject of controversy. We aimed to examine the role of H19 in chronic inflammation-mediated hepatocarcinogenesis using the Mdr2/Abcb4 knockout (Mdr2-KO) mouse, a well-established HCC model. For this goal, we have generated Mdr2-KO/H19-KO double knockout (dKO) mice and followed spontaneous tumor development in the dKO and control Mdr2-KO mice. Cellular localization of H19 and effects of H19 loss in the liver were determined in young and old Mdr2-KO mice. Tumor incidence and tumor load were both significantly decreased in the liver of dKO versus Mdr2-KO females. The expression levels of H19 and Igf2 were variable in nontumor liver tissues of Mdr2-KO females and were significantly downregulated in most matched tumors. In nontumor liver tissue of aged Mdr2-KO females, H19 was expressed mainly in hepatocytes, and hepatocyte proliferation was increased compared to dKO females. At an early age, dKO females displayed lower levels of liver injury and B-cell infiltration, with higher percentage of binuclear hepatocytes. In human samples, H19 expression was higher in females, positively correlated with cirrhosis (in nontumor liver samples) and negatively correlated with CTNNB1 (beta-catenin) mutations and patients' survival (in tumors). Our data demonstrate that the lncRNA H19 is pro-oncogenic during the development of chronic inflammation-mediated HCC in the Mdr2-KO mouse model, mainly by increasing liver injury and decreasing hepatocyte polyploidy in young mice.

Abstract
Following partial hepatectomy (PH), the complex process of liver regeneration is initiated, which encompasses the synchronized induction of hepatocyte proliferation. Hepatocyte proliferation can be regulated by multiple stimuli, including long non-coding RNAs (lncRNAs) and Wnt/β-catenin signaling, although the underlying mechanism of lncRNA/Wnt in liver regeneration remains unclear. In the present study, a liver regeneration-associated functional lncRNA was identified, and its function was delineated in vitro and in vivo; lncRNA small nucleolar RNA host gene 12 (SNHG12) was revealed to be upregulated at various time-points after 2/3 PH. The expression of SNHG12 was also increased in normal liver cell lines treated with different concentrations of hepatocyte growth factor (HGF). Functionally, SNHG12 enhanced hepatocyte proliferation in vitro and in vivo, and the liver/body weight ratio of SNHG12-overexpressing mice was significantly higher than that of the control mice. Overexpression of SNHG12 promoted the activation of Wnt/β-catenin signaling in hepatocytes. Furthermore, specific inhibition of Wnt/β-catenin signaling significantly attenuated SNHG12-induced hepatocyte proliferation and the affected liver/body weight ratio. Collectively, the results of the present study indicated that SNHG12 contributes to liver regeneration by activating Wnt/β-catenin signaling. Therefore, drugs that regulate the SNHG12/Wnt axis may be beneficial for liver regeneration following PH.

Abstract
INTRODUCTION Extracellular vesicles (EVs) are cell-secreted packages that deliver cargo to target cells to effect functional and phenotypic changes. They are secreted by many different cell types, including adipose-derived stem cells (ADSCs), which are a promising field of study in regenerative medicine. Our aim was to perform a systematic review of the literature to summarize the scientific work that has been conducted on ADSC EVs to date. METHODS The Pubmed database was queried with keywords (and variations of) "adipose derived stem cell," "stromal vascular fraction," and "extracellular vesicles." We excluded review papers, then manually screened articles based on title and abstract. Full-text articles were assessed for eligibility to include in final review. RESULTS While an extensive body of research exists on EVs, a much smaller proportion of that is original research on ADSC EVs. Of 44 manuscripts that met our database search criteria, 21 articles were selected for our systematic review. CONCLUSION ADSC EVs were found to exert effects on angiogenesis, cell survival and apoptosis, inflammation, tissue regeneration, and reduction of disease pathology. Further studies examine characteristics of ADSC EVs. Future work should aim to further detail the safety profiles of ADSC EVs given their potential for cell-based therapies. The body of research studies characterizing ADSC EVs continues to expand, and much work remains to be done before human pilot studies can be considered. To our knowledge, we offer the first systematic review summarizing the research on ADSC EVs and their determined roles to date.

Abstract
Long noncoding RNA (lncRNA) H19 is abundantly expressed in fetal liver. Its expression is significantly diminished in adult healthy liver but is re‐induced in chronic liver diseases, including cholestasis. In this study, we developed a new method with combined in situ hybridization (ISH) and immunofluorescence (IF) colabeling to establish an H19 expression profile with both parenchymal and nonparenchymal cell‐specific markers in the livers of cholestatic mouse models and patients with cholestasis. H19RNA+ cells showed no colocalization with biliary epithelial cell marker cytokeratin 19 (CK19)+ cholangiocytes but were immediately adjacent to biliary structures in bile duct ligation (BDL), 3,5‐diethoxycarbony1‐1,4‐dihydrocollidine (DDC), and multidrug‐resistant gene 2 knockout (Mdr2–/–) mouse models and in human primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC) liver specimens. In contrast, double‐positive H19RNA+/sex‐determining region Y (SRY)‐box 9 (SOX9)+ ductal progenitor cells, H19RNA+/hepatocyte nuclear factor 4α (HNF4α)+ hepatocytes, H19RNA+/F4/80+ Kupffer cells, HNF4α+/SOX9+ hybrid hepatocytes, as well as triple‐positive H19RNA+/HNF4α+/SOX9+ periportal hepatocytes were identified. In addition, H19RNA could not be detected in mesenchymal cell marker desmin+ cells. Furthermore, H19RNA was predominately detected in cytoplasm with a small amount at the interspace with neighboring cells. Conclusion:H19RNA is localized in HNF4α+ periportal hepatocytes, SOX9+ ductal progenitor cells, and F4/80+ Kupffer cells but not in CK19+ cholangiocytes and desmin+ stellate cells in cholestatic livers.

Abstract
It has previously been reported that human adipose-derived stem cells (hASCs) can promote the regeneration of damaged tissues in rats with liver failure through a ‘paracrine effect’. Here we demonstrate a therapeutic effect of hASCs derived Extracellular Vesicles (EVs) on rat models with acute liver failure, as shown by the improvement of the survival rate by >70% compared to controls. Gene sequencing of rat liver revealed an increase in human long-chain non-coding RNA (lncRNA) H19 after hASC-derived EVs transplantation. When the H19 coding sequence was silenced in hASCs and EVs were then collected for treatment of rats with liver failure, we saw a decrease in the survival rate to 40%, compared to treatment with EVs generated from non-silenced hASCs. These data indicate that lncRNA H19 may be a potential therapeutic target for the treatment of liver failure.

Abstract
H19 RNA is highly expressed at early postnatal ages and precipitously decreases at a specific time corresponding with increases in expression of genes important for mature liver function, such as drug metabolizing enzymes. H19’s role in the regulation of liver maturation is currently unknown. Using an H19 knockout mouse model to determine the role of H19 in liver development, we quantified gene expression for insulin growth factor signaling, Wnt signaling, key cytochrome P450 (P450) enzymes known to change as the liver develops, and fetal and adult plasma protein produced in liver. In mice lacking H19 expression, liver weights were significantly increased immediately after birth and significant increases were found in the number of actively proliferating cells. Increases in cell proliferation may be due to increases in β-catenin protein affecting Wnt signaling, increases in insulin-like growth factor 2 (IGF2) expression, and/or increases in insulin-like growth factor 1 receptor (IGF1R) expression at the protein level. Loss of targeted inhibition of IGF1R by microRNA 675 (miR-675) may be the cause of IGF1R increases, as miR-675 expression is also abrogated with loss of H19 expression in our model. P450 expression patterns were largely unchanged. No change in the production of plasma proteins was found, indicating H19 may not be important for liver maturation despite its role in controlling cell proliferation during liver growth. H19 may be important for normal liver development, and understanding how the liver matures will assist in predicting drug efficacy and toxicity in pediatric populations.

Abstract
H19 is a long non-coding RNA regulated by genomic imprinting through methylation at the locus between H19 and IGF2. H19 is important in normal liver development, controlling proliferation and impacting genes involved in an important network controlling fetal development. H19 also plays a major role in disease progression, particularly in hepatocellular carcinoma. H19 participates in the epigenetic regulation of many processes impacting diseases, such as activating the miR-200 pathway by histone acetylation to inhibit the epithelial-mesenchymal transition to suppress tumor metastasis. Furthermore, H19's normal regulation is disturbed in diseases, such as hepatocellular carcinoma. In this disease, aberrant epigenetic maintenance results in biallelic expression of IGF2, leading to uncontrolled cellular proliferation. This review aims to further research utilizing H19 for drug discovery and the treatment of liver diseases by focusing on both the epigenetic regulation of H19 and how H19 regulates normal liver functions and diseases, particularly by epigenetic mechanisms.

Abstract
Exploring the biological functions of long non-coding RNAs (lncRNAs) has come to the foreground in recent years. Studies have indicated that the lncRNA metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) not only regulates tumorigenesis in hepatocellular carcinoma, but also controls cell cycle progression in hematopoietic cells. The present study was designed to investigate the biological role of lncRNA MALAT1 in liver regeneration. We carried out a series of assays during liver regeneration following 2/3 partial hepatectomy in mice. We explored the functions of lncRNA MALAT1 with a series of functional analyses in vitro. We found that MALAT1 was upregulated during liver regeneration. Moreover, MALAT1 accelerated hepatocyte proliferation by stimulating cell cycle progression from the G1 to the S phase and inhibiting apoptosis in vitro. In addition, our findings also demonstrated that MALAT1 was regulated by p53 during liver regeneration, and that p53 may be a key upstream regulator of MALAT1 activity. Mechanistically, we found that MALAT1 activated the Wnt/β-catenin pathway by inhibiting the expression of Axin1 and adenomatous polyposis coli (APC), and subsequently promoting the expression of cyclin D1. On the whole, the findings of this study suggest that MALAT1 is a critical molecule for liver regeneration. Pharmacological interventions targeting MALAT1 may thus prove to be therapeutically beneficial in liver failure or liver transplantation by promoting liver regeneration.

Abstract
Prohibitin 1 (PHB1) is a mitochondrial chaperone that regulates cell growth. Phb1 knock-out mice exhibit liver injury and hepatocellular carcinoma (HCC). Phb1 knock-out livers show induction of tumor growth-associated genes, H19 and insulin-like growth factor 2 (Igf2). These genes are controlled by the imprinting control region (ICR) containing CCCTC-binding transcription factor (CTCF)-binding sites. Because Phb1 knock-out mice exhibited induction of H19 and Igf2, we hypothesized that PHB1-mediated regulation of the H19-Igf2 axis might control cell proliferation in normal hepatocytes. H19 and Igf2 were induced (8-20-fold) in 3-week-old Phb1 knock-out livers, in Phb1 siRNA-treated AML12 hepatocytes (2-fold), and HCC cell lines when compared with control. Phb1 knockdown lowered CTCF protein in AML12 by ∼30% when compared with control. CTCF overexpression lowered basal H19 and Igf2 expression by 30% and suppressed Phb1 knockdown-mediated induction of these genes. CTCF and PHB1 co-immunoprecipitated and co-localized on the ICR element, and Phb1 knockdown lowered CTCF ICR binding activity. The results suggest that PHB1 and CTCF cooperation may control the H19-Igf2 axis. Human HCC tissues with high levels of H19 and IGF2 exhibited a 40-50% reduction in PHB1 and CTCF expression and their ICR binding activity. Silencing Phb1 or overexpressing H19 in the mouse HCC cell line, SAMe-D, induced cell growth. Blocking H19 induction prevented Phb1 knockdown-mediated growth, whereas H19 overexpression had the reverse effect. Interestingly H19 silencing induced PHB1 expression. Taken together, our results demonstrate that the H19-Igf2 axis is negatively regulated by CTCF-PHB1 cooperation and that H19 is involved in modulating the growth-suppressive effect of PHB1 in the liver.

Abstract
Helicobacter hepaticus infection of A/JCr mice is a model of infectious liver cancer. We monitored hepatic global gene expression profiles in H. hepaticus infected and control male A/JCr mice at 3 months, 6 months, and 1 year of age using an Affymetrix-based oligonucleotide microarray platform on the premise that a specific genetic expression signature at isolated time points would be indicative of disease status. Model based expression index comparisons generated by dChip yielded consistent profiles of differential gene expression for H. hepaticus infected male mice with progressive liver disease versus uninfected control mice within each age group. Linear discriminant analysis and principal component analysis allowed segregation of mice based on combined age and lesion status, or age alone. Up-regulation of putative tumor markers correlated with advancing hepatocellular dysplasia. Transcriptionally down-regulated genes in mice with liver lesions included those related to peroxisome proliferator, fatty acid, and steroid metabolism pathways. In conclusion, transcriptional profiling of hepatic genes documented gene expression signatures in the livers of H. hepaticus infected male A/JCr mice with chronic progressive hepatitis and preneoplastic liver lesions, complemented the histopathological diagnosis, and suggested molecular targets for the monitoring and intervention of disease progression prior to the onset of hepatocellular neoplasia.

Abstract
Recent studies have shown that metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) was overexpressed in many human solid cancers, however, its roles in plasma of hepatocellular carcinoma (HCC) patients were unclear. The aim of this study was to investigate the significance of plasma MALAT1 levels in HCC patients. Plasma samples were collected from pre-operative HCC, hepatic disease patients, and healthy controls, and tissue samples from HCC patients and colorectal cancer patients with liver metastasis. Plasma and tissue MALAT1 levels were measured. Plasma MALAT1 levels were progressively and significantly higher in HCC patients than hepatic disease patients, and higher in hepatic disease patients than healthy controls. The expression of MALAT1 in HCC tissue was slightly higher than that in paired non-cancerous liver tissue, but not significant. The expression of MALAT1 in the non-cancerous liver tissue of 20 HCC patients was significantly higher than that in normal liver tissue of 13 colorectal cancer patients. In contrast, plasma MALAT1 levels were significantly low in HCC patients with hepatitis B infection, and significantly high in patients with liver damage B or liver cirrhosis. In a receiver-operator curve analysis of HCC and hepatic disease patients, the cut-off value of plasma MALAT1 was 1.60 and the area under the curve was 0.66. Plasma MALAT1 levels were not correlated with α-fetoprotein or protein induced by vitamin K absence II, whereas sensitivity and specificity for the detection of HCC with the combination of MALAT1, α-fetoprotein, and protein induced by vitamin K absence II were 88.6% and 75%, respectively. In conclusion, the plasma MALAT1 level is associated with liver damage, and has clinical utility for predicting development of HCC.

Abstract
Hepatocellular carcinoma develops in either chronically injured or seemingly intact livers. To explore the tumorigenic mechanisms underlying these different conditions, we compared the mRNA expression profiles of mouse hepatocellular tumors induced by the repeated injection of CCl4 or a single diethylnitrosamine (DEN) injection using a cDNA microarray. We identified tumor-associated genes that were expressed differentially in the cirrhotic CCl4 model (H19, Igf2, Cbr3, and Krt20) and the non-cirrhotic DEN model (Tff3, Akr1c18, Gpc3, Afp, and Abcd2) as well as genes that were expressed comparably in both models (Ly6d, Slpi, Spink3, Scd2, and Cpe). The levels and patterns of mRNA expression of these genes were validated by quantitative RT-PCR analyses. Most of these genes were highly expressed in mouse livers during the fetal/neonatal periods. We also examined the mRNA expression of these genes in mouse tumors induced by thioacetamide, another cirrhotic inducer, and those that developed spontaneously in non-cirrhotic livers and found that they shared a similar expression profile as that observed in CCl4-induced and DEN-induced tumors, respectively. There was a close relationship between the expression levels of Igf2 and H19 mRNA, which were activated in the cirrhotic models. Our results show that mouse liver tumors reactivate fetal/neonatal genes, some of which are specific to cirrhotic or non-cirrhotic modes of pathogenesis.

Abstract
MicroRNAs (miRNAs) are small, regulatory non-coding RNAs that have potent effects on gene expression. Several miRNA are deregulated in cellular processes involved in human liver diseases and regulation of cellular processes. Recent studies have identified the involvement of miR-29 in hepatic fibrosis and carcinogenesis. Although several targets of miR-29 have been identified, there is limited information regarding the cell-type specific roles of miR-29 in the liver, and we sought to evaluate the role of this miRNA in hepatic pathobiology. We report the generation of a tissue–specific knockout mouse to evaluate the role of miR-29 in hepatic fibrosis and carcinogenesis in response to injury. We hypothesized that miR-29 contributes to the hepatocyte driven response to chronic cellular injury that results in fibrosis. In support of this hypothesis, fibrosis and mortality were enhanced in miR29 knockout mice in response to carbon tetrachloride. Genome-wide gene expression analysis identified an over-representation of genes associated with fibrosis. The oncofetal RNA H19 was modulated in a miR-29 dependent manner following exposure to carbon tetrachloride in vivo. The impact of a hepatocyte specific miR-29 knockout on survival following chronic hepatic injury in vivo implicates this miRNA as a potential target for intervention. These results provide evidence of the involvement of miR-29 in chronic hepatic injury, and suggest a role for deregulated hepatocyte expression of miR-29 in the response to hepatic injury, fibrosis and carcinogenesis.

Abstract
UNLABELLED In recent years, long noncoding RNAs (lncRNAs) have been investigated as a new class of regulators of biological function. A recent study reported that lncRNAs control cell proliferation in hepatocellular carcinoma (HCC). However, the role of lncRNAs in liver regeneration and the overall mechanisms remain largely unknown. To address this issue, we carried out a genome-wide lncRNA microarray analysis during liver regeneration in mice after 2/3 partial hepatectomy (PH) at various timepoints. The results revealed differential expression of a subset of lncRNAs, notably a specific differentially expressed lncRNA associated with Wnt/β-catenin signaling during liver regeneration (an lncRNA associated with liver regeneration, termed lncRNA-LALR1). The functions of lncRNA-LALR1 were assessed by silencing and overexpressing this lncRNA in vitro and in vivo. We found that lncRNA-LALR1 enhanced hepatocyte proliferation by promoting progression of the cell cycle in vitro. Furthermore, we showed that lncRNA-LALR1 accelerated mouse hepatocyte proliferation and cell cycle progression during liver regeneration in vivo. Mechanistically, we discovered that lncRNA-LALR1 facilitated cyclin D1 expression through activation of Wnt/β-catenin signaling by way of suppression of Axin1. In addition, lncRNA-LALR1 inhibited the expression of Axin1 mainly by recruiting CTCF to the AXIN1 promoter region. We also identified a human ortholog RNA of lncRNA-LALR1 (lncRNA-hLALR1) and found that it was expressed in human liver tissues. CONCLUSION lncRNA-LALR1 promotes cell cycle progression and accelerates hepatocyte proliferation during liver regeneration by activating Wnt/β-catenin signaling. Pharmacological intervention targeting lncRNA-LALR1 may be therapeutically beneficial in liver failure and liver transplantation by inducing liver regeneration.

Abstract
Non-coding RNA (ncRNA), a class of RNAs that do not code protein but have regulatory functions, can regulate gene expression and replication of hepatitis B virus or hepatitis C virus and play an important role in the virus-host interaction and the development of hepatocellular carcinoma (HCC). Deregulated ncRNAs in surgically removed hepatic tissues and circulation can be prognostic and diagnostic markers, respectively. ncRNAs functioning as either tumor suppressors or oncogenes can be therapeutic options. Here, we summarize the deregulated ncRNAs associated with the infections and HCC and focus on their roles on early diagnosis, prognosis prediction and therapeutic option of HCC.

Abstract
The embryos of some rodents and primates can precede early development without the process of fertilization; however, they cease to develop after implantation because of restricted expressions of imprinting genes. Asexually developed embryos are classified into parthenote/gynogenote and androgenote by their genomic origins. Embryonic stem cells (ESCs) derived from asexual origins have also been reported. To date, ESCs derived from parthenogenetic embryos (PgESCs) have been established in some species, including humans, and the possibility to be alternative sources for autologous cell transplantation in regenerative medicine has been proposed. However, some developmental characteristics, which might be important for therapeutic applications, such as multiple differentiation capacity and transplantability of the ESCs of androgenetic origin (AgESCs) are uncertain. Here, we induced differentiation of mouse AgESCs and observed derivation of neural cells, cardiomyocytes and hepatocytes in vitro. Following differentiated embryoid body (EB) transplantation in various mouse strains including the strain of origin, we found that the EBs could engraft in theoretically MHC-matched strains. Our results indicate that AgESCs possess at least two important characteristics, multiple differentiation properties in vitro and transplantability after differentiation, and suggest that they can also serve as a source of histocompatible tissues for transplantation.

Abstract
We previously developed a highly aggressive cell line from heart metastases of 4T1 breast carcinoma (designated 4THM), which produced liver metastases (designated 4TLM). In this study, gene array analysis (GAEA) compared gene expression profiles in 4TLM with profiles in 4T1 and 4THM primary tumors. GAEA demonstrated that 4T1 and 4THM tumors differed in about 250 genes. Over 1,000 genes, however, were expressed differently in 4TLM compared with primary tumors. A cohort of 16 genes showed significantly decreased expression in 4THM tumors, which decreased even further in 4TLM. Many of these genes have been implicated in breast cancer, and many are involved in cell adhesion and junctional complexes. Expression of multiple tight and adherence junction proteins was either downregulated or disappeared in 4TLM; downregulation of claudin 4, claudin 7 and gamma-catenin was confirmed by quantitative polymerase chain reaction, immunoblot, and immunocytochemical (ICC) analyses. At the protein level, intact ZO-1 was also observed in 4T1 tumors, but was not expressed in 4THM or 4TLM tumors. ICC demonstrated expression of gamma-catenin at the plasma membrane with 4T1 tumors, whereas staining appeared to be nuclear/perinuclear in 4THM tumors. Claudin 7 staining was also seen in monocyte/pmacrophage-like cells in liver around metastatic lesions by ICC, and it appeared that larger 4TLM tumors apparently reexpressed claudin 7 RNA and protein. Our results demonstrate that decreased or abnormal expression of a number of cell adhesion/junctional proteins, including claudin 4, 7, ZO-1 and gamma-catenin, correlates with liver metastases, and that cell adhesion molecules in the microenvironment are also altered.

Abstract
The expression of the H19 gene has been well studied in fetal human and mouse tissues but not in cattle. It is generally believed that H19 is abundantly expressed in the early stages of embryogenesis and is repressed postnatally. We report the expression pattern of this gene in cattle in a total of 120 fetal-organ combinations and in a total of 108 adult-organ combinations using quantitative real time PCR. In fetal tissues, H19 was abundantly expressed in amnion, chorion, and allantois. Fetal liver, lung, heart, spleen, eye, rib, mammary gland, and cotyledon showed moderate expression, while intestine and brain showed lower expression levels. For some organs examined in this study, the expression pattern in cattle fetal organs was similar to that of human, mouse, and sheep. For adult organs, H19 was highly expressed in muscle and moderately expressed in liver, lung, heart, kidney, pancreas, and ovary. Low expression levels were observed for adult spleen, caruncle, and endometrium. Of considerable interest was the observation that H19 transcripts have not been detected in the mouse and human kidney or in the mouse spleen. In contrast, we observed significant expression levels in adult kidney and low expression levels in adult spleen. In a comparison of adults and fetuses, significant differences in H19 expression levels were found for liver, lung, heart, and spleen. The expression pattern in adults implies that, in addition to possible roles in embryogenesis, the H19 gene may have other functions.

How does human stem cell therapy influence gene expression after liver injury? Microarray evaluation on a rat model. Dig Liver Dis 2005; 37:952-63. [PMID: 16214431 DOI: 10.1016/j.dld.2005.06.012] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/04/2005] [Accepted: 06/22/2005] [Indexed: 12/11/2022]
Abstract
BACKGROUND Tissue homeostasis is guaranteed by stem proliferating reserve, depending on dynamic changes in gene expression. A high plasticity is shown by the haematopoietic stem cells, potential source for liver regeneration. AIM We aimed to evaluate the gene expression modifications induced by human haematopoietic stem cell therapy after liver injury in rats. SUBJECTS Rats were sorted as follows: (A) human-haematopoietic stem cell injection after allyl alcohol liver damage; (B) only haematopoietic stem cell injection; (C) only allyl alcohol injection; and (D) sacrifice without any treatment. METHODS Livers, spleens and bone marrows were analysed with flow-cytometry. Livers were also studied by reverse-transcription PCR, histology, immunohistochemistry and microarray analysis; selected genes were confirmed by real-time PCR. RESULTS In subset A, haematopoietic stem cells were selectively recruited by liver, with respect to the group B, and they improved the liver regeneration process compared to group C. As regards microarrays, haematopoietic stem cell infusion upregulates 265 genes and downregulates 149 genes. Differentially regulated genes belong to a broad range of functional pathways, including proliferation, differentiation, adhesion/migration and transcripts related to oval-cell activation. Real-time PCR validated array results. CONCLUSIONS Our study confirmed the capacity of haematopoietic stem cells to contribute to liver regeneration. Moreover, microarray analysis led to the identification of genes whose regulation strongly correlates with a more efficient process of liver repair after haematopoietic stem cell injection.
