Abstract
BACKGROUND Laparoscopic liver resection (LLR) is rapidly gaining popularity; however, its efficacy for nonalcoholic fatty liver disease (NAFLD)-associated hepatocellular carcinoma (HCC) (NAFLD-HCC) has been not evaluated. The purpose of this study was to compare short- and long-term outcomes between LLR and open liver resection (OLR) among patients with NAFLD-HCC. METHODS We used a single-institution database to analyze data for patients who underwent LLR or OLR for NAFLD-HCC from January 2007 to December 2022. We performed propensity score-matching analyses to compare overall postoperative complications, major morbidities, duration of surgery, blood loss, transfusion, length of stay, recurrence, and survival between the two groups. RESULTS Among 210 eligible patients, 46 pairs were created by propensity score matching. Complication rates were 28% for OLR and 11% for LLR (p = 0.036). There were no significant differences in major morbidities (15% vs. 8.7%, p = 0.522) or duration of surgery (199 min vs. 189 min, p = 0.785). LLR was associated with a lower incidence of blood transfusion (22% vs. 4.4%, p = 0.013), less blood loss (415 vs. 54 mL, p < 0.001), and shorter postoperative hospital stay (9 vs. 6 days, p < 0.001). Differences in recurrence-free survival and overall survival between the two groups were not statistically significant (p = 0.222 and 0.301, respectively). CONCLUSIONS LLR was superior to OLR for NAFLD-HCC in terms of overall postoperative complications, blood loss, blood transfusion, and postoperative length of stay. Moreover, recurrence-free survival and overall survival were comparable between LLR and OLR. Although there is a need for careful LLR candidate selection according to tumor size and location, LLR can be regarded as a preferred treatment for NAFLD-HCC over OLR.

Abstract
BACKGROUND Adverse outcomes of cirrhosis remain a top priority. AIMS We examined the distribution of cirrhosis causes, HCC incidence and mortality and related changes over time in a nationwide U.S. COHORT METHODS A retrospective study of a national sample of commercially insured patients with cirrhosis from Optum's de-identified Clinformatics® Data Mart Database (CDM). RESULTS A total of 628,743 cirrhosis cases were identified with 45% having NAFLD, 19.5% HCV, and 16.3% ALD. African Americans had the highest rate of decompensation (60.6%), while Asians had the highest rate of HCC (2.4%), both p < 0.001. African Americans more frequently had HCV (28.4%) while Hispanic/Latinos more frequently had NAFLD (49.2%, p < 0.001). Patients in the 2014-2021 cohort were significantly older (63.0 ± 12.8 vs. 57.0 ± 14.3), less frequently decompensated (54.5% vs. 58.3%) but more frequently had HCC (1.7% vs. 0.6%) and NAFLD (46.5% vs. 44.2%), all p < 0.001. The overall annual incidence of HCC was 0.76% (95% CI: 0.75-0.77) with a 5-year cumulative incidence of 4.03% (95% CI: 3.98-4.09), with significant variation by sex, race/ethnicity, and cirrhosis aetiology. The overall median years of survival were 11.4 (95% CI: 11.3-11.5) with a 5-year cumulative survival of 73.4% (95% CI: 73.3%-73.6%), also with significant disparities in similar subgroups (lowest in cryptogenic cirrhosis and worse in 2014-2021 vs. 2003-2013). The 2014-2021 period was independently associated with worse survival (aHR: 1.14, 95% CI: 1.08-1.20). CONCLUSIONS HCC incidence and survival vary by aetiology among patients with cirrhosis, with cryptogenic cirrhosis having the lowest survival and lower survival in the more recent time period.

Abstract
Background & Aim Causes of hepatocellular carcinoma (HCC) may change as treatments become available for some liver diseases. We examined the distribution of HCC cause and survival of a nationwide cohort of insured patients. Methods Optum's de-identified Clinformatics® Data Mart Database (CDM), 2003-2021. Results A total of 34707 patients with HCC were included: mean age: 68.3±11.6 years, 61% male, 62% Caucasian, 74% cirrhosis. Non-alcoholic fatty liver disease (NAFLD) was the most common etiology (38.9%), then hepatitis C virus (HCV) (25.3%), cryptogenic (18.0%), alcohol-associated liver disease (9.4%), other liver diseases (5.8%) and hepatitis B virus (HBV) at 2.6%. NAFLD patients were the oldest (mean age 71.1±11.2) and had the highest Charlson Comorbidity Index (CCI) (mean 10.5±3.9), while HCV were the youngest (mean age 64.2±9.2 years) and HBV had the lowest CCI (mean 7.2±4.4) (both P<0.0001). The overall 5-year survival was 18.8% (95% CI 18.2-19.3) but was lower in the recent 2014-2021 period vs 2003-2013 (18.1% vs 19.5%, P=0.003). The 2014-2021 cohort (inclusive of HCV treatment advances) was significantly older, with more females, fewer Caucasians, more African Americans, more Hispanics, fewer Asians, more cirrhosis, more NAFLD, and higher CCI (all P<0.001). On multivariable analysis, males (aHR: 1.13), Caucasians (aHR: 1.46), African Americans (aHR: 1.53) and Hispanics (aHR: 1.28) vs Asians, 2014-2021 (vs 2003-2013) cohort (aHR: 1.12), NAFLD (aHR: 1.14) or cryptogenic liver disease (aHR: 1.45) were associated with increased mortality (all P<0.001). Conclusion HCC patients in more recent time 2014-2021 were more likely to be older, more likely to have nonviral etiology, and had worse survival compared to those from 2003 to 2013.

Survival Improvements in Advanced Hepatocellular Carcinoma with Sequential Therapy by Era. Cancers (Basel) 2023; 15:5298. [PMID: 37958471 PMCID: PMC10650854 DOI: 10.3390/cancers15215298] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2023] [Revised: 11/02/2023] [Accepted: 11/03/2023] [Indexed: 11/15/2023] Open
Abstract
Treatment modalities for advanced hepatocellular carcinoma (HCC) have changed dramatically, with systemic therapy as the primary option. However, the effect of sequential treatment on prognosis remains unclear. This retrospective study included patients who began systemic therapy between 2009 and 2022. The patients were separated into three groups according to systemic therapy commencement. The number of therapy lines, treatment efficacy, and overall survival (OS) were compared. Multivariate analyses of the prognostic factors were analyzed using the Cox proportional hazards model. Overall, 336 patients were included (period 1: 2009-2013, n = 86; period 2: 2014-2018, n = 132; period 3: 2019-2022, n = 118). A significant etiological trend was observed with decreasing viral hepatitis-related HCC and increasing non-viral hepatitis-related HCC. Across periods 1-3, the proportion of patients who were administered >2 lines progressively increased (1.2%, 12.9%, and 17.0%, respectively; p < 0.001) and the median OS was significantly prolonged (14.3, 16.8, and 31.0 months; p < 0.001). The use of <3 lines, the non-complete and partial response of the first line, modified albumin-bilirubin at grade 2b or 3, an intrahepatic tumor number ≥ 5, extrahepatic metastasis, and alpha-fetoprotein at ≥400 ng/mL were the strongest factors associated with shorter OS. Sequential therapies have contributed to significant improvements in HCC prognosis, suggesting that sequential treatment post-progression is worthwhile for better survival.

Abstract
BACKGROUND/AIMS Understanding of nonalcoholic fatty liver disease (NAFLD) continues to expand, but the relationship between race and ethnicity and NAFLD outside the use of cross-sectional data is lacking. Using longitudinal data, we investigated the role of race and ethnicity in adverse outcomes in NAFLD patients. METHODS Patients with NAFLD confirmed by imaging via manual chart review from any clinics at Stanford University Medical Center (1995-2021) were included. Primary study outcomes were incidence of liver events and mortality (overall and non-liver related). RESULTS The study included 9,340 NAFLD patients: White (44.1%), Black (2.29%), Hispanic (27.9%), and Asian (25.7%) patients. For liver events, the cumulative 5-year incidence was highest among White (19.1%) patients, lowest among Black (7.9%) patients, and similar among Asian and Hispanic patients (~15%). The 5-year and 10-year cumulative overall mortality was highest for Black patients (9.2% and 15.0%, respectively, vs. 2.5-3.5% and 4.3-7.3% in other groups) as well as for non-liver mortality. On multivariable regression analysis, compared to White patients, only Asian group was associated with lower liver-related outcomes (aHR: 0.83, P=0.027), while Black patients were at more than two times higher risk of both non-liver related (aHR: 2.35, P=0.010) and overall mortality (aHR: 2.13, P=0.022) as well as Hispanic patients (overall mortality: aHR: 1.44, P=0.022). CONCLUSION Compared to White patients, Black patients with NAFLD were at the highest risk for overall and non-liver-related mortality, followed by Hispanic patients with Asian patients at the lowest risk for all adverse outcomes. Culturally sensitive and appropriate programs may be needed for more successful interventions.

Abstract
Hepatocellular carcinoma (HCC) continues to be a serious medical problem with poor prognosis worldwide. The distribution of the major etiologies of HCC is changing due to the progress of anti-viral treatments, including hepatitis B virus (HBV) suppression by nucleoside/nucleotide analogues (NAs) and increased sustained virologic response (SVR) rates by direct-acting antivirals (DAAs) for hepatitis C virus (HCV), as well as the rising trend of nonviral liver disease. Although viral hepatitis remains the most common cause of HCC, non-alcoholic liver disease (NAFLD) with metabolic syndrome and alcohol-associated liver disease (ALD) are increasing. Effective and well-tolerated NAs treatment can slow the disease progression of chronic HBV infection to cirrhosis, end-stage liver disease, and reduce HCC risk. Treatment with NAs is also associated with significant improvement in the long-term survival of patients with HBV infection who already have HCC. DAAs have achieved viral elimination in almost all patients with HCV without significant adverse events, even in patients with decompensated liver cirrhosis and HCC. Similarly, DAA therapy can reduce disease progression, liver and non-liver complications, and improve the long-term survival of patients with chronic HCV infection with or without HCC. Meanwhile, NAFLD is a rapidly increasing cause of HCC along with the epidemics of obesity and type 2 diabetes globally. NAFLD-related HCC can occur in patients without cirrhosis and is known to have a lower survival rate than viral hepatitis-related HCC. Since there is currently no specific pharmacotherapy effective for NAFLD, lifestyle modification and prevention of complications are important to improve prognosis. Additionally, ALD is the second fastest-growing cause of HCC-related deaths, especially with an accelerated trend since the COVID-19 pandemic. This review provides an overview of the epidemiologic trends in the etiologies of HCC, and the progress of treatments for each etiology and the impact on outcome in the patients with HCC.

Abstract
Hepatocellular carcinoma (HCC) is the most common primary liver cancer and is the sixth most frequent cancer in the world, being the third cause of cancer-related deaths. Nonalcoholic steatohepatitis (NASH) is characterized by fatty infiltration, oxidative stress and necroinflammation of the liver, with or without fibrosis, which can progress to advanced liver fibrosis, cirrhosis and HCC. Obesity, metabolic syndrome, insulin resistance, and diabetes exacerbates the course of NASH, which elevate the risk of HCC. The growing prevalence of obesity are related with increasing incidence of NASH, which may play a growing role in HCC epidemiology worldwide. In addition, HCC initiation and progression is driven by reprogramming of metabolism, which indicates growing appreciation of metabolism in the pathogenesis of this disease. Although no specific preventive pharmacological treatments have recommended for NASH, dietary restriction and exercise are recommended. This review focuses on the molecular connections between HCC and NASH, including genetic and risk factors, highlighting the metabolic reprogramming and aberrant epigenetic alterations in the development of HCC in NASH. Current therapeutic aspects of NASH/HCC are also reviewed.

Abstract
Non-alcoholic fatty liver disease (NAFLD) occurs in 25% of the global population and manifests as lipid deposition, hepatocyte injury, activation of Kupffer and stellate cells, and steatohepatitis. Predominantly expressed in hepatocytes, the augmenter of liver regeneration (ALR) is a key factor in liver regulation that can alleviate fatty liver disease and protect the liver from abnormal liver lipid metabolism. ALR has three isoforms (15-, 21-, and 23-kDa), amongst which 23-kDa ALR is the most extensively studied. The 23-kDa ALR isoform is a sulfhydryl oxidase that resides primarily in the mitochondrial intermembrane space (IMS), whereby it protects the liver against various types of injury. In this review, we describe the role of ALR in regulating hepatocytes in the context of NAFLD. We also discuss questions about ALR that remain to be explored in the future. In conclusion, ALR appears to be a promising therapeutic target for treating NAFLD.

[PMID: 33387668 PMCID: PMC8243558 DOI: 10.1016/j.cgh.2020.12.029] [Citation(s) in RCA: 32] [Impact Index Per Article: 16.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/24/2020] [Revised: 12/22/2020] [Accepted: 12/24/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND AND AIMS Hepatocellular carcinoma (HCC) is the fastest rising cause of cancer-related death in the United States; however, HCC incidence and mortality are not equally distributed among racial and ethnic groups. Our aim was to characterize the direction and magnitude of racial and ethnic disparities in overall survival and early tumor detection among patients with HCC. METHODS We searched MEDLINE, EMBASE and Cochrane databases from inception through August 2020 for studies reporting HCC outcomes (early stage presentation and overall survival) by race and ethnicity. We calculated pooled hazard ratios (HRs) and odds ratios (ORs) for each racial and ethnic group (White, Black, Hispanic, Asian) using the DerSimonian and Laird method for a random-effects model. RESULTS We identified 35 articles comprising 563,097 patients (53.0% White, 17.3% Black, 18.4% Hispanic, 5.0% Asian). Compared with White patients, Black patients had worse survival (pooled HR 1.08; 95% CI, 1.05 - 1.12), whereas Hispanic (pooled HR 0.92; 95% CI, 0.87 - 0.97) and Asian (pooled HR 0.81; 95% CI, 0.73 - 0.88) patients had better survival. Among articles reporting tumor stage (n = 20), Black patients had lower odds of early stage HCC compared with White patients (OR, 0.66; 95% CI, 0.54 - 0.78). Conversely, there was no difference in odds of early HCC detection for Asian (OR, 1.01; 95% CI, 0.97 - 1.05) or Hispanic patients (OR, 0.87; 95% CI, 0.74 - 1.01) compared with White patients. The most common limitation of studies was risk of residual confounding from socioeconomic status and liver dysfunction. CONCLUSIONS There are significant racial and ethnic disparities in HCC prognosis in the United States, with Black patients having worse overall survival and Hispanic and Asian patients having better overall survival compared with White patients. Interventions are needed to reduce disparities in early HCC detection to improve HCC prognosis.

Abstract
Background With the rising incidence of hepatocellular carcinoma (HCC), ongoing efforts should be focused on providing equitable and state-of-the-art care to patients. Purpose The aim of this study was to determine the survival of patients with HCC seen at a high-proportion Safety Net Hospital (h-SNH), where loco-regional therapy and hepatology services are available and liver transplantation (LT) is referred to outside facilities. Patients and Methods A retrospective cohort study was conducted on all patients with HCC seen at Valley Wise Health Center (VWHC) over a ten-year period. Clinical variables, treatment modalities, survival duration, hospice, and LT referrals of 161 patients were collected from the medical records. Survival analysis was used to determine the relationship of clinically relevant variables and survival among patients with HCC. A Log rank test was used to compare univariate variables. A Cox regression analysis was used to compare and control for multiple variables. Results Of the 161 patients included in the study, 33% were uninsured. The median age was 59 (21 to >89) years with 47% Hispanic, 31% Caucasian, 15% African American and 7% other races included for the analysis. The median survival for the cohort was 20.1 months. In the multivariate model, insurance status, final MELD, tumor within the Milan criteria and having received treatment for HCC were associated with survival. Surveillance for HCC was associated with HCC in the univariate analysis, but not in the multivariable model. Thirty percent of patients were referred for LT and 1.25% of the entire cohort received it. Conclusion Despite the availability of treatment modalities available for HCC at VWHC and the option of liver transplantation for appropriate candidates at outside centers, OS was less than reported from programs with on-site liver transplant programs. Reasons for lower survival in centers without liver transplant programs should be further studied.

Abstract
PURPOSE The purpose of this study was to investigate the influences of sex comb on midleg like-2 (SCML2) on hepatocellular carcinoma (HCC) and potentially related mechanisms. MATERIALS AND METHODS SCML2 expression in tumor tissues and cells was analyzed using the TCGA database and/or qRT-PCR. The proliferation of HCC cells was detected by CCK-8, colony formation, and EdU assays. The migration and invasion of HCC cells were detected by transwell and wound healing assays. Apoptosis of HCC cells was determined by flow cytometry. Additionally, qRT-PCR and Western blot were used to detect the expression of SCML2 and Wnt/β-catenin/epithelial-mesenchymal transition (EMT) signaling. A xenograft model in mice was established to verify the in vitro findings. RESULTS We found that SCML2 was highly expressed in HCC tissues and cells and that high expression of SCML2 was correlated with poor prognosis in HCC patients. SCML2 overexpression promoted proliferation, invasion, and migration and repressed apoptosis of HCC cells. The reverse results were obtained in SCML2-silenced cells. Further, we found that SCML2 activated the Wnt/β-catenin/EMT pathway. SCML2 silencing reduced the protein levels of Wnt3a, β-catenin, N-cadherin, Vimentin, and Snail and enhanced E-cadherin protein expression both in vivo and in vitro. CONCLUSION SCML2 silencing inhibits the proliferation, migration, and invasion of HCC cells by regulating the Wnt/β-catenin/EMT pathway.

Abstract
The prevalence of hepatocellular carcinoma (HCC) is increasing worldwide, whereas that of most other cancers is decreasing. Non-alcoholic fatty liver disease (NAFLD), which has increased with the epidemics of obesity and type 2 diabetes, increases the risk of HCC. Interestingly, NAFLD-associated HCC can develop in patients with or without cirrhosis. A lack of awareness about NAFLD-related HCC has led to delays in diagnosis. Therefore, a large number of patients with HCC are diagnosed with advanced-stage HCC with low 5-year survival. In this context, increasing awareness of NAFLD and NAFLD-related HCC may lead to earlier diagnosis and more effective interventions.

Abstract
BACKGROUND & AIMS The benefits of hospice care in Medicare recipients with hepatocellular carcinoma (HCC) have not been fully evaluated, which we aimed to study. METHODS We used nationally representative samples of the Medicare beneficiaries in the USA (2011-2016) to assess the impact of hospice care on the outcomes of patients with HCC. Hospice care benefits on the survival time, length of stay (LOS), 30-day readmissions, and daily charges during the last year and month of life were assessed by logistic regression and generalised linear regression. RESULTS Among 2,230 Medicare beneficiaries with HCC (mean age, 74.9 years; non-Hispanic White 79.1%; male 66.6%), median survival from HCC diagnosis was 68 days; 556 (24.9%) received hospice services; median hospice LOS was 12 days (4-35 days). Hospice users increased from 20.1% to 31.1% over time, driven by enrolment ≤15 days (45.1-59.2%, respectively). In the last year of life, hospice users (vs. no hospice care) had longer median survival time (76.5 vs. 66 days), lower in-hospital mortality (1.1% vs. 25.5%) and lower median daily charges ($951 vs. $1,004) despite more inpatient admissions and higher comorbid diseases. Hospice enrolment was associated with 48.6% reduction in daily charges (95% CI: -54.9% to -41.5%). Longer hospice LOS was associated with lower rates of healthcare utilisation. Patients with chronic liver disease were less likely to enrol in hospice care (odds ratio = 0.18, 95% CI: 0.14-0.24). CONCLUSIONS Although hospice provides a significant decrease in healthcare utilisation and some benefit in survival, most care is given in the last 2 weeks of life. Efforts to encourage earlier use of hospice services must continue. LAY SUMMARY The purpose of hospice care is to provide comfort and lessen suffering at the end of life. Hospice care allows one to die outside the hospital environment which is the wish of most people. However, we found that among persons aged 65 years and older who were diagnosed with liver cancer (which has a poor prognosis), only 25% were enrolled in hospice care and the majority used a hospice only in the last weeks of life. This is a disheartening finding as liver cancer patients with longer hospice enrolment had lower costs and improved survival. We suggest that healthcare practitioners consider discussion of palliative and hospice care routinely with patients suffering from liver cancer.

Abstract
BACKGROUND & AIMS The profile of chronic liver disease (CLD) in the United States has changed due to obesity trends and advances in treatment of viral hepatitis. We assessed liver transplant listing trends by CLD etiology. METHODS Adult candidates for liver transplantation were selected from the Scientific Registry of Transplant Recipients (2002 through 2019). We calculated proportion trends for common CLD etiologies at time of placement on the wait list, including chronic infection with hepatitis B virus, chronic infection with hepatitis C virus (HCV), nonalcoholic steatohepatitis (NASH, including cryptogenic cirrhosis), alcohol-related liver disease (ALD) without or with chronic HCV infection, autoimmune hepatitis, primary biliary cholangitis, and primary sclerosing cholangitis, in patients with and without hepatocellular carcinoma (HCC). RESULTS From the 168,441 patients with known etiology and non-acute liver failure on the liver transplant waitlist, 27,799 patients (16.5%) had HCC. In 2002, the most common etiologies in patients without HCC were chronic HCV infection (37%) and ALD (16%), whereas only 5% had NASH. Among patients with HCC, 58% had chronic HCV infection and 10% had ALD and only 1% had NASH. In 2019, among patients without HCC, NASH was the second leading indication for liver transplantation (28% of patients), after ALD (38% of patients). Among patients with HCC, chronic HCV infection remained the leading indication (40% of patients) but NASH (24% of patients) surpassed ALD (16% of patients) to become the second leading indication. NASH was the leading indication in women without HCC (34%), in patients older than 54 years (36%), and in patients on Medicare (41%). In trend analysis, NASH was the most rapidly increasing indication for liver transplantation in patients without HCC (Kendall tau=0.97; P < .001) and in patients with HCC (tau=0.94; P < .0001). CONCLUSIONS In an analysis of data from the Scientific Registry of Transplant Recipients (2002 through 2019), we found NASH to be the second most common indication for liver transplant in 2019, and the fastest increasing indication. In 2019, NASH was the leading indication for liver transplantation among women without HCC.

Abstract
BACKGROUND It is uncertain whether the prognosis of Barcelona Clinical Liver Cancer (BCLC) stage 0 hepatocellular carcinoma (HCC) has improved. AIMS To evaluate whether the outcomes of BCLC stage 0 patients has improved, and if so, what are the reasons behind the noted improved outcome. METHODS A total of 591 patients with BCLC stage 0 HCC diagnosed at Samsung Medical Center, Seoul, Korea were grouped based on year of diagnosis (earlier cohort; 2007-2009 and later cohort; 2013-2015) and compared. RESULTS The overall survival (OS) was improved for BCLC stage 0 patients at later cohort (5-year survival rate: 82.1% vs. 92.0% for earlier cohort and later cohort, p = 0.015). However, after adjustment, the treatment period was not an independent factor for OS, especially when the albumin-bilirubin (ALBI) grade was adjusted. The incidence of liver cirrhosis (LC)-related death was increased from 10.4% to 33.3%, while the incidence of HCC-related death decreased from 57.5% to 28.6% in the latter cohort. CONCLUSIONS The survival improvement of BCLC stage 0 patients was largely explained by better liver function at diagnosis. Mortality from LC-related death was increasing, which calls for careful attention for finding strategies for preserving the liver function for BCLC stage 0 patients.

Abstract
The early diagnosis and treatment of liver hepatocellular carcinoma (LIHC) remains a major challenge. Therefore, it is of great significance to strengthen basic research on LIHC in order to improve the prevention and treatment of the disease. Numerous studies have indicated that the PI3K/Akt and FoxO signaling pathways mediate proliferation, survival and migration during the development of LIHC. Therefore, they have become a target for LIHC treatment. Furthermore, let-7c has been demonstrated to repress cell proliferation, migration and invasion, and to induce G1 phase arrest and apoptosis of LIHC cells. However, the mechanism of its action is not clear. In the present study, the association between let-7c and the PI3K/Akt/FoxO signaling pathway, as well as their roles in the development of LIHC were investigated using The Cancer Genome Atlas and various public databases (Tumor-miRNA-Pathway, OncomiR, DIANA-TarBase v8, KOBAS 3.0, ONCOMINE, Kaplan-Meier plotter, LinkedOmics, UALCAN and cBioPortal). The effects of let-7c-5p on PI3K/Akt/FoxO signaling pathway-related target genes were analyzed following overexpression of let-7c-5p in the MHCC-97H cell line via reverse transcription-quantitative PCR, and the let-7c-5p target genes belonging to the PI3K/Akt/FOXO signaling pathway in LIHC were screened out. GO and KEGG enrichment analyses of these target genes was performed using g:Profiler, gOST. In addition, GeneMANIA and Search Tool for the Retrieval of Interacting Genes/Proteins (STRING) databases were used to determine the gene-gene and protein-protein interaction networks, respectively. The data demonstrated that cyclin B2 (CCNB2), cyclin E2 (CCNE2), cyclin dependent kinase 4 (CDK4), homer scaffold protein 1 (HOMER1), heat shock protein 90 α family class A member 1 (HSP90AA1), neuroblastoma RAS viral oncogene homolog (NRAS), protein phosphatase 2 catalytic subunit α (PPP2CA), protein kinase AMP-activated catalytic subunit α2 (PRKAA2) and Rac family small GTPase 1 (RAC1) may be target genes of let-7c-5p. These genes, particularly CCNE2, were associated with poor overall survival and could be promising candidate biomarkers for disease and poor prognosis in LIHC. Among them, seven genes (CCNE2, CDK4, HSP90AA1, NRAS, PPP2CA, PRKAA2 and RAC1) belonged to the PI3K-Akt signaling pathway and four genes (CCNB2, HOMER1, NRAS and PRKAA2) belonged to the FoxO signaling pathway. The majority of these genes were closely associated with the cell cycle and their elevated expression may aggravate cell cycle disorders. Therefore, let-7c may be considered to be an anti-oncogene of LIHC. The present study may provide novel targets and strategies for the diagnosis and treatment of LIHC.

Abstract
Objective This study aims to explore the mechanism of the miR-424-5p/E2F7 axis in hepatocellular carcinoma (HCC) and provide new ideas for targeted therapy of HCC. Methods Bioinformatics analysis was used to identify the target differentially expressed miRNA in HCC and predict its target gene. qRT-PCR was employed to verify the expression of miR-424-5p and E2F7 mRNA in HCC cells. Western blot was performed to detect the effect of miR-424-5p ectopic expression on the protein expression of E2F7. CCK-8 was used to detect proliferative activity of HCC cells and flow cytometry was carried out for analyzing cell cycle distribution. Dual luciferase reporter assay was conducted to verify the direct targeting relationship between miR-424-5p and E2F7. Results We observed that miR-424-5p was down-regulated in HCC cells. CCK-8 showed that overexpression of miR-424-5p inhibited cell proliferation, and flow cytometry showed that miR-424-5p could block cells in G0/G1 phase. E2F7 was up-regulated in HCC cells, and E2F7 overexpression could facilitate the proliferative ability of HCC cells and promote the cell cycle progressing from G0/G1 to S phase. Furthermore, dual-luciferase reporter assay indicated that miR-424-5p could directly down-regulate E2F7 expression. Analysis on cell function demonstrated that miR-424-5p inhibited the proliferation of HCC cells and blocked cell cycle at G0/G1 phase by targeting E2F7. Conclusion Our results proved that E2F7 was a direct target of miR-424-5p, and miR-424-5p could regulate cell cycle and further inhibit the proliferation of HCC cells by targeting E2F7.

Abstract
AIMS Liver hepatocellular carcinoma (LIHC) is the main manifestation of primary liver cancer, with low survival rate and poor prognosis. Medical decision-making process of LIHC is so complex that new biomarkers for diagnosis and prognosis have yet to be explored, this study aimed to identify the genes involved in the pathophysiology of LIHC and biomarkers that can be used to predict the prognosis of LIHC. METHODS Six Gene Expression Omnibus (GEO) datasets selected from GEO were screened and integrated to find out the differential expression genes (DEGs) obtained from LIHC and normal hepatic tissues. The Gene Ontology and Kyoto Encyclopaedia of Genes and Genomes pathway enrichment analysis of DEGs was implemented by DAVID. The Protein-protein interaction network was performed via STRING. In addition, Cox regression model was used to construct a gene prognostic signature. RESULTS We ascertained 10 hub genes, nine of them (CDK1, CDC20, CCNB1, Thymidylate synthetase, Nuclear division cycle80, NUF2, MAD2L1, CCNA2 and BIRC5) as biomarkers of progression in LIHC patients. We also build a six gene prognosis signature (SOCS2, GAS2L3, NLRP5, TAF3, UTP11 and GAGE2A), which can be implemented to predict over survival effectively. CONCLUSIONS We revealed promising genes that may participate in the pathophysiology of LIHC, and found available biomarkers for LIHC prognosis prediction, which were significant for researchers to further understand the molecular basis of LIHC and direct the synthesis medicine of LIHC.

Abstract
BACKGROUND Despite an increasing burden of nonalcoholic steatohepatitis (NASH), limited data are available comparing outcomes of NASH-related hepatocellular carcinoma (HCC) versus other etiologies. METHODS Patient demographic and tumor characteristics were collected for 1,051 patients diagnosed with NASH-, alcohol-related liver disease (ALD)-, hepatitis C virus (HCV)-, and hepatitis B virus (HBV)-related HCC at 2 large health systems from January 2008 through December 2016. Patient demographics, clinical characteristics, and survival were compared. Risk-adjusted treatment receipt and overall survival (OS) were examined using multivariable analysis. RESULTS A total of 92 patients with NASH-related HCC were compared with 153 patients with ALD-, 719 with HCV-, and 87 with HBV-related HCC. Patients with NASH were older, more likely female, and more likely Hispanic white. Patients with NASH and HBV had more compensated liver disease than those with ALD or HCV, including significantly higher proportions having noncirrhotic HCC. Despite similar surveillance receipt and Barcelona Clinic Liver Cancer (BCLC) tumor stage at diagnosis, patients with NASH had higher rates of curative-intent therapy than those with other diseases. Unadjusted median OS was 16 months for NASH, 15 months for ALD, 14 months for HCV, and 8 months for HBV. In multivariable analysis, NASH was associated with worse OS compared with ALD (hazard ratio, 1.92; 95% CI, 1.3-2.5), but there was no difference between NASH- and HCV- or HBV-related HCC. CONCLUSIONS Patients with NASH-related HCC present with more preserved liver function, including a higher proportion having noncirrhotic HCC, than other diseases. Despite patients having similar tumor stage at diagnosis, NASH is independently associated with worse survival compared with ALD, but similar survival compared with HCV and HBV.

LncRNA FTX represses the progression of non-alcoholic fatty liver disease to hepatocellular carcinoma via regulating the M1/M2 polarization of Kupffer cells. Cancer Cell Int 2020; 20:266. [PMID: 32595415 PMCID: PMC7315496 DOI: 10.1186/s12935-020-01354-0] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2020] [Accepted: 06/15/2020] [Indexed: 01/06/2023] Open
Abstract
Background The effect of lncRNA FTX on non-alcoholic fatty liver disease (NAFLD) conversion to hepatocellular carcinoma (HCC) is unclear. Methods In our study, C57BL/6 mice was fed with high fat diet for obtaining NAFLD mouse model, and diethylnitrosamine induced the formation of HCC tumor. The expression of iNOS and CD206 in tissues were examined using immunohistochemistry. In addition, qRT-PCR was implemented to detect the expression of FTX and mRNAs. The percentage of M1 and M2 Kupffer cells (KCs) were determined using flow cytometry. The pathological change in liver tissues was displayed by H&E staining. Besides, immunofluorescence assay was performed to ensure the primary KCs through labeling F4/80. Results Here, we found that the expression of FTX and the ratio of M1/M2 KCs in liver tissues from NAFLD-transformed HCC (NAFLD-HCC) patients lower than in liver tissues from NAFLD patients. Subsequently, we revealed that the expression of FTX and M1/M2 KCs ratio were downregulated during NAFLD conversion to HCC. Importantly, increasing of FTX inhibited HCC tumor growth, improved liver damage and promoted M1 polarization of KCs during NAFLD conversion to HCC, while these effects of FTX were reversed by inactivating of KCs. Finally, in vitro experiments, our data indicated that FTX facilitated the M1 polarization of KCs. Conclusion In conclusion, our results demonstrated that upregulation of FTX suppressed NAFLD conversion to HCC though promoting M1 polarization of KCs. Our findings presented a new regulatory mechanism for NAFLD conversion to HCC, and provided a new biomarker for inhibiting this conversion.

Abstract
BACKGROUND AND AIMS Survival data among patients with hepatitis C virus (HCV)-related hepatocellular carcinoma (HCC) after achieving sustained virologic response (SVR) with interferon-free direct-acting antivirals (DAAs) in both Asian and western countries are limited. Survival rates were compared between patients with HCV-related HCC who were untreated for HCV and those who achieved SVR. APPROACH AND RESULTS Using data from two U.S. and six Asian centers from 2005 to 2017, we categorized 1,676 patients who were mono-infected with HCV-related HCC into patients untreated for HCV (untreated group) and DAA-treated patients with SVR (SVR group) and matched by propensity score matching (PSM); multivariable Cox regression with HCV treatment status as a time-varying covariate was used to determine mortality risk and landmark analysis to avoid immortal time bias. There were 1,239 untreated patients and 437 patients with SVR. After PSM, background risks of the 321 pairs of matched patients were balanced (all P > 0.05). After time-varying adjustment for HCV treatment initiation compared with untreated patients, patients with SVR had significantly higher 5-year overall survival (87.78% vs. 66.05%, P < 0.001). Multivariable Cox regression showed that SVR was independently associated with a 63% lower risk of 5-year all-cause mortality (hazard ratio [HR], 0.37; 95% confidence interval [CI], 0.16-0.83; P = 0.016) and 66% lower risk of 5-year liver-related mortality (HR, 0.34; 95% CI, 0.13-0.88; P = 0.026) with similar trends after removing patients with liver transplants. Landmark analysis at 90, 180, and 360 days showed consistent results (HRs ranged 0.22 to 0.44, all P < 0.05). CONCLUSION In this multinational consortium, patients with HCV-related HCC who obtained SVR achieved a 60%-70% improvement in 5-year survival (both all-cause and liver related) compared with patients untreated for HCV. Patients eligible for HCC therapy should also be considered for DAA therapy.

Synergism of wt-p53 and synthetic material in local nano-TAE gene therapy of hepatoma: comparison of four systems and the possible mechanism. BMC Cancer 2019; 19:1126. [PMID: 31747895 PMCID: PMC6868790 DOI: 10.1186/s12885-019-6162-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2019] [Accepted: 09/13/2019] [Indexed: 01/10/2023] Open
Abstract
Background TAE-gene therapy for hepatoma, incorporating the tumor-targeted therapeutic efficacy of trans-arterial embolization, hydroxyapatite nanoparticles (nHAP) and anti-cancer wild-type p53 gene (wt-p53), was presented in our former studies (Int J Nanomedicine 8:3757-68, 2013, Liver Int 32:998-1007, 2012). However, the incompletely antitumoral effect entails defined guidelines on searching properer materials for this novel therapy. Methods Unmodified nHAP, Ca(2+) modified nHAP, poly-lysine modified nHAP and liposome were separately used to form U-nanoplex, Ca-nanoplex, Pll-nanoplex, L-nanoplex respectively with wt-p53 expressing plasmid. The four nanoplexs were then applied in vitro for human normal hepacyte L02 and hepatoma HePG2 cell line, and in vivo for rabbits with hepatic VX2 tumor by injection of nanoplexs/lipiodol emulsion into the hepatic artery in a tumor target manner. The distribution, superficial potential, physical structure, morphology and chemical compositions of nanoplexs were evaluated by TEM, SEM, EDS etc., with the objective of understanding their roles in hepatoma TAE-gene therapy. Results In vitro, L-nanoplex managed the highest gene transferring efficiency. Though with the second highest transfection activity, Pll-nanoplex showed the strongest tumor inhibition activity while maintaining safe to the normal hepacyte L02. In fact, only Pll-nanoplex can combine both the antitumoral effect to HePG2 and safe procedure to L02 among the four systems above. In vivo, being the only one with successful gene transference to hepatic VX2 tumor, Pll-nanoplex/lipiodol emulsion can target the tumor more specifically, which may explain its best therapeutic effect and hepatic biologic response. Further physical characterizations of the four nanoplexs suggested particle size and proper electronic organic surface may be crucial for nano-TAE gene therapy. Conclusion Pll-nanoplex is the most proper system for the combined therapy due to its selectively retention in liver cancer cells, secondary to its morphological and physico-chemical properties of nanometric particle size, steady emulsion, proper organic and electronic surface.

Abstract
Increasing evidence has indicated the important roles of long noncoding RNA small nucleolar RNA host gene 7 (SNHG7) in tumourigenesis as a potential oncogene. However, the function of SNHG7 in hepatic carcinoma remains unclear. In the present study, we found that SNHG7 expression was significantly upregulated in hepatic carcinoma tissues, especially in aggressive cases, and it was closely correlated with the poor prognosis. Furthermore, knockdown of SNHG7 inhibited the proliferation, migration, and invasion of hepatic carcinoma cell lines in vitro. Mechanistically, SNHG7 directly interacted with miR‐425 as a ceRNA. Moreover, knockdown of SNHG7 significantly inhibited the tumorigenic Wnt/β‐catenin/EMT pathway. SNHG7 regulated Wnt/β‐catenin/EMT pathway through sponging miR‐425 and played an oncogenic role in hepatic carcinoma progression. Together, our study elucidated the role of SNHG7 as a ceRNA in hepatic carcinoma, provided new potential diagnosis and therapeutic application in hepatic carcinoma progression. Significance of the study SNHG7 could promote proliferation and metastasis of hepatic carcinoma cell in vitro and in vivo, suggesting that SNHG7 exerts tumorigenic role in hepatic carcinoma progression. Further mechanism research revealed that SNHG7 exhibited the tumorigenic role through Wnt/β‐catenin/EMT pathway as a miR‐425 sponge. These findings provided new cues to understand the molecular signalling network in carcinogenesis of hepatic carcinoma, and it may provide new evidence for therapeutic application in hepatic carcinoma.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is becoming a major etiological risk factor for hepatocellular carcinoma (HCC) in the United States and other Western countries. In this study, we investigated the role of gene-specific promoter cytosine DNA methylation and gene expression alterations in the development of NAFLD-associated HCC in mice using (1) a diet-induced animal model of NAFLD, (2) a Stelic Animal Model of nonalcoholic steatohepatitis-derived HCC, and (3) a choline- and folate-deficient (CFD) diet (CFD model). We found that the development of NAFLD and its progression to HCC was characterized by down-regulation of glycine N-methyltransferase (Gnmt) and this was mediated by progressive Gnmt promoter cytosine DNA hypermethylation. Using a panel of genetically diverse inbred mice, we observed that Gnmt down-regulation was an early event in the pathogenesis of NAFLD and correlated with the extent of the NAFLD-like liver injury. Reduced GNMT expression was also found in human HCC tissue and liver cancer cell lines. In in vitro experiments, we demonstrated that one of the consequences of GNMT inhibition was an increase in genome methylation facilitated by an elevated level of S-adenosyl-L-methionine. Overall, our findings suggest that reduced Gnmt expression caused by promoter hypermethylation is one of the key molecular events in the development of NAFLD-derived HCC and that assessing Gnmt methylation level may be useful for disease stratification.

A reliable LC-MS/MS method for the quantification of natural amino acids in mouse plasma: Method validation and application to a study on amino acid dynamics during hepatocellular carcinoma progression. J Chromatogr B Analyt Technol Biomed Life Sci 2019; 1124:72-81. [PMID: 31177050 DOI: 10.1016/j.jchromb.2019.05.039] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2019] [Revised: 05/17/2019] [Accepted: 05/31/2019] [Indexed: 01/15/2023]
Abstract
A simple and fast LC-MS/MS method was developed and validated for simultaneous quantification of 20 proteinogenic l-amino acids (AAs) in a small volume (5 μL) of mouse plasma. Chromatographic separation was achieved on an Intrada Amino Acid column within 13 min via gradient elution with an aqueous solution containing 100 mM ammonium formate and an organic mobile phase containing acetonitrile, water and formic acid (v:v:v = 95:5:0.3), at the flow rate of 0.6 mL/min. Individual AAs and corresponding stable-isotope-labeled AAs internal standards were analyzed by multiple reaction monitoring (MRM) in positive ion mode under optimized conditions. Method validation consisted of linearity, sensitivity, accuracy and precision, recovery, matrix effect, and stability, and the results demonstrated this LC-MS/MS method as a specific, accurate, and reliable assay. This LC-MS/MS method was thus utilized to compare the dynamics of individual plasma AAs between healthy and orthotopic hepatocellular carcinoma (HCC) xenograft mice housed under identical conditions. Our results revealed that, 5 weeks after HCC tumor progression, plasma l-arginine concentrations were significantly decreased in HCC mice while l-alanine and l-threonine levels were sharply increased. These findings support the utilities of this LC-MS/MS method and the promise of specific AAs as possible biomarkers for HCC.

Abstract
The present study aimed to examine the apoptotic effects of adenovirus (ADV)-mediated herpes simplex virus thymidine kinase (ADV-TK) combined with ganciclovir (GCV) in tissues obtained from patients with hepatocellular carcinoma in order to provide a theoretical basis for the development of this gene therapy program. Apoptosis detection was conducted using the terminal deoxynucleotidyl-transferase-mediated dUTP nick end labelling assay and the apoptosis index was compared between the experimental; and control groups. Furthermore, the protein expression levels of caspase-3, B-cell lymphoma-2 (Bcl-2), Bcl-2-assoicated protein X (Bax) and nuclear factor (NF)-κB were examined in pathological specimens using immunohistochemical staining. The Bax/Bcl-2 ratio and the release of cytochrome c were examined using western blot analysis. Results indicated that combined ADV-TK and GCV treatment significantly increased the number of apoptotic cells compared with the control group (P<0.05). Immunohistological analysis revealed that ADV-TK and GCV treatment significantly increased the number of caspase-3-positive cells, reduced the Bax/Bcl-2 ratio and NF-κB expression levels and promoted the release of cytochrome c compared with the control group (P<0.01). In conclusion, the present results suggest that combined ADV-TK and GCV treatment exerts its effect through the apoptotic signaling pathway.

Abstract
Hepatocellular carcinoma (HCC) remains a leading cause of cancer-related deaths, warranting better therapies. Restoration of tumor-suppressive microRNAs depleted in hepatocellular carcinoma represents a new therapeutic strategy. Herein, we sought to identify a potent microRNA (miRNA) agent that could alleviate HCC tumor burden and improve survival. Among a collection of bioengineered noncoding RNA molecules produced through bacterial fermentation, we identified let-7c agent as the most potent inhibitor of HCC cell viability. Bioengineered let-7c selectively modulated target gene expression (Lin-28 homolog B [LIN28B], AT-rich interactive domain-containing protein 3B [ARID3B], B cell lymphoma-extra large [Bcl-xl], and c-Myc) in HCC cells, and consequently induced apoptosis and inhibited tumorsphere growth. When formulated with liposomal-branched polyethylenimine polyplex, bioengineered let-7c exhibited serum stability up to 24 h. Furthermore, liposomal polyplex-formulated let-7c could effectively reduce tumor burden and progression in orthotopic HCC mouse models, while linear polyethyleneimine-formulated let-7c to a lower degree, as revealed by live animal and ex vivo tissue imaging studies. This was also supported by reduced serum α-fetoprotein and bilirubin levels in let-7c-treated mice. In addition, lipopolyplex-formulated let-7c extended overall survival of HCC tumor-bearing mice and elicited no or minimal immune responses in healthy immunocompetent mice and human peripheral blood mononuclear cells. These results demonstrate that bioengineered let-7c is a promising molecule for advanced HCC therapy, and liposomal polyplex is a superior modality for in vivo RNA delivery.

Abstract
BACKGROUND Economic burden of HBV and HCV infection are trending upwards. AIMS Compare hepatitis B virus (HBV) and hepatitis C virus (HCV) related hospital admission rates, charges, mortality rates, causes of death in a US population-based study. METHODS Retrospective cohort analysis of HBV and HCV patients from the California Office of Statewide Health Planning and Development (2006-2013) database. RESULTS A total of 23,891 HBV and 148,229 HCV patients were identified. Across the 8-year period, the mean increase for all-cause ($1,863 vs $1,388) and liver-related hospitalization charges ($1,175 vs $675) were significantly higher for the HBV cohort compared to the HCV cohort. HBV patients had significantly higher liver-related hospital charges per person per year than HCV patients after controlling for covariates ($123,239 vs $111,837; p = 0.002). Compared to HCV patients, adjusted mortality hazard ratio was slightly lower in HBV patients (relative risk = 0.96; 95% CI 0.94-0.99). The major causes and places of death were different. The three major causes of death for HBV were: other malignant neoplasms (35%), cardiovascular disease/other circulatory disorders (17%), and liver-related disease (15%) whereas for HCV patients were: liver-related disease (22%), other malignant neoplasms (20%), and cardiovascular disease (16%). Regarding the place of death, 53% of HBV patients and 44% of HCV patients died in hospital inpatient, respectively. CONCLUSIONS HBV patients incurred higher liver-related hospital charges and higher mean increase for all-cause and liver-related hospitalization charges over the 8-year period compared to HCV patients. HBV patients had slightly lower mortality rate and their major causes and places of death were noticeably different from HCV patients.
