Glycogen metabolism plays a key role in the development of hepatoellular carcinoma(HCC),but the function of glycogen metabolism genes in the tumor microenvironment(TME)is still to be elucidated.Single cell RNA-seq data were obtained from ten HCC tumor samples totaling 64,545 cells and 65 glycogen metabolism genes were analyzed bya nonnegative matrix factorization(NMF).The prognosis and immune response of new glycogen TME cell dusters were predicted by using HCC and immunotherapy cohorts from public databases.HOC single cell analysis was divided into fibroblasts,NT T cells,macrophages,endothelial clls,and B cells,which were separately divided into new cell clusters by glycogen metabolism gene annotation.Pseudo temporal trajectory analysis demonstrated the temporal differentiation trajectory of different glycogen subtype cell dusters.Cellular communication analysis revealed extensive interactions between endothelial cells with glycogen metabolizing TME cell.related subtypes and diferent glycogen subtype cell clusters.SCENIC analysis of transcription factors upstream of TME cell clusters with different glycogen metabolism.In addition,TME cell dusters of glycogen metabolism were found to be enriched in expression in CAF subtypes,CD8 depleted,M1,and M2 types.Bulk seq analysis showed the prognostic signifcance of glycogen metabolism.mediated TME cell dusters in HCC,while a significant immune response was found in the immunotherapy cohort in patients treated with immune checkpoint blockade(ICB),especially for CAFs,T cells,and macrophages In summary,our study reveals for the first time that glycogen metabolism mediates intercellular communication in the hepatocellular carcinoma microenvironment while elucidating the anti-tumor mechanisms and immune prognostic responses of different subtypes of cell dusters. 展开更多

Over the past 2 decades,cancer stem cells(CSCs)have been identified as the root cause of cancer occurrence,progression,chemoradioresistance,recurrence,and metastasis.Targeting CSCs is a novel therapeutic strategy for cancer management and treatment.Liver cancer(LC)is a malignant disease that can endanger human health.Studies are increasingly suggesting that changes in the liver mechanical microenvironment are a primary driver triggering the occurrence and development of liver cancer.In this review,we summarize current understanding of the roles of the liver mechano-microenvironment and liver cancer stem cells(LCSCs)in liver cancer progression.We also discuss the relationship between the mechanical heterogeneity of liver cancer tissues and LCSC recruitment and metastasis.Finally,we highlight potential mechanosensitive molecules in LCSCs and mechanotherapy in liver cancer.Understanding the roles and regulatory mechanisms of the mechano-microenvironment and LCSCs may provide fundamental insights into liver cancer progression and aid in further development of novel therapeutic strategies. 展开更多

Hepatocellular carcinoma(HCC),which develops from liver cirrhosis,is highly prevalent worldwide and is a malignancy that leads to liver failure and systemic metastasis.While surgery is the preferred treatment for HCC,intervention and liver transplantation are also treatment options for end-stage liver disease.However,the success of partial hepatectomy and intervention is hindered by the decompensation of liver function.Conversely,liver transplantation is difficult to carry out due to its high cost and the lack of donor organs.Fortunately,research into bone-marrow stromal cells(BMSCs)has opened a new door in this field.BMSCs are a type of stem cell with powerful proliferative and differential potential that represent an attractive tool for the establishment of successful stem cell-based therapy for liver diseases.A number of different stromal cells contribute to the therapeutic effects exerted by BMSCs because BMSCs can differentiate into functional hepatic cells and can produce a series of growth factors and cytokines capable of suppressing inflammatory responses,reducing hepatocyte apoptosis,reversing liver fibrosis and enhancing hepatocyte functionality.Additionally,it has been shown that BMSCs can increase the apoptosis rate of cancer cells and inhibit tumor metastasis in some microenvironments.This review focuses on BMSCs and their possible applications in liver regeneration and metastasis after hepatectomy. 展开更多

Although viral hepatitis treatments have evolved over the years, the resultant liver cirrhosis still does not completely heal. Platelets contain proteins required for hemostasis, as well as many growth factors required for organ development, tissue regeneration and repair. Thrombocytopenia, which is frequently observed in patients with chronic liver disease(CLD) and cirrhosis, can manifest from decreased thrombopoietin production and accelerated platelet destruction caused by hypersplenism; however, the relationship between thrombocytopenia and hepatic pathogenesis, as well as the role of platelets in CLD, is poorly understood. In this paper, experimental evidence of platelets improving liver fibrosis and accelerating liver regeneration is summarized and addressed based on studies conducted in our laboratory and current progress reports from other investigators. In addition, we describe our current perspective based on the results of these studies. Platelets improve liver fibrosis by inactivating hepatic stellate cells, which decreases collagen production. The regenerative effect of platelets in the liver involves a direct effect on hepatocytes, a cooperative effect with liver sinusoidal endothelial cells, and a collaborative effect with Kupffer cells. Based on these observations, we ascertained the direct effect of platelet transfusion on improving several indicators of liver function in patients with CLD and liver cirrhosis. However, unlike the results of our previous clinical study, the smaller incremental changes in liver function in patients with CLD who received eltrombopag for 6 mo were due to patient selection from a heterogeneous population. We highlight the current knowledge concerning the role of platelets in CLD and cancer and anticipate a novel application of platelet-based clinical therapies to treat liver disease. 展开更多

In the last years,several studies have been focused on elucidate the role of tumor microenvironment(TME)in cancer development and progression.Within TME,cells from adaptive and innate immune system are one of the main abundant components.The dynamic interactions between immune and cancer cells lead to the activation of complex molecular mechanisms that sustain tumor growth.This important cross-talk has been elucidate for several kind of tumors and occurs also in patients with liver cancer,such as hepatocellular carcinoma(HCC)and intrahepatic cholangiocarcinoma(iCCA).Liver is well-known to be an important immunological organ with unique microenvironment.Here,in normal conditions,the rich immune-infiltrating cells cooperate with non-parenchymal cells,such as liver sinusoidal endothelial cells and Kupffer cells,favoring self-tolerance against gut antigens.The presence of underling liver immunosuppressive microenvironment highlights the importance to dissect the interaction between HCC and iCCA cells with immune infiltrating cells,in order to understand how this cross-talk promotes tumor growth.Deeper attention is,in fact,focused on immune-based therapy for these tumors,as promising approach to counteract the intrinsic anti-tumor activity of this microenvironment.In this review,we will examine the key pathways underlying TME cell-cell communications,with deeper focus on the role of natural killer cells in primary liver tumors,such as HCC and iCCA,as new opportunities for immune-based therapeutic strategies. 展开更多

The current treatments of liver cancer in China are mainly comprehensive treatment and systematic treatment, with poor therapeutic effect and high recurrence rate and metastasis rate. The existence of immunosuppressive microenvironment is an important reason for liver tumor cells to escape from the host immune system, and also an important basis for the occurrence and development of liver cancer. With the recent transformation of the target of tumor therapy from tumor cells to tumor cell immune microenvironment, immunotherapy has emerged quietly. It is a new strategy for the treatment of hepatocellular carcinoma to improve the immune attack on tumor cells by changing the immunosuppressive environment of hepatocellular carcinoma cells. Immune checkpoint is the main mechanism by which liver cancer cells escape the host immune system. PD-1/PDL-1 and CTLA-4 are targeted immunocheckpoint inhibitors, which have shown good therapeutic effects and application prospects in the clinical treatment of HCC. This article reviews the latest advances in immunocheckpoint inhibitors in the immunotherapy of hepatocellular carcinoma. 展开更多

Microcirculation of liver cancer is the micro-vascular system which comes from the tissue of liver cancer. It can offer the nutritional requirement for accelerating the cancer cell proliferation and metastasis. The intrinsic mechanism of angiogenesis is the key link in the formation of liver cancer microcirculation system. Liver regeneration microenvironment also plays an important role in the construction of liver cancer microcirculation, through the improvement of liver regeneration microenvironment affecting tumor microcirculation is the new strategy of prevention and treatment of liver cancer. In recent years, it is found that many kinds of Chinese medicine can inhibit angiogenesis, decrease the microvessel density, and delay or prevent the development of liver cancer. 展开更多

The occurrence and development of liver cancer are essentially the most serious outcomes of uncontrolled liver regeneration. The progression of liver cancer is inevitably related to the abnormal microenvironment of liver regeneration. The deterioration observed in the microenvironment of liver regeneration is a necessary condition for the occurrence, development and metastasis of cancer. Therefore, the use of a technique to prevent and treat liver cancer via changes in the microenvironment of liver regeneration is a novel strategy. This strategy would be an effective way to delay, prevent or even reverse cancer occurrence, development and metastasis through an improvement in the liver regeneration microenvironment along with the integrated regulation of multiple components, targets, levels, channels and time sequences. In addition, the treatment of "tonifying Shen(Kidney) to regulate liver regeneration and repair by affecting stem cells and their microenvironment" can regulate "the dynamic imbalance between the normal liver regeneration and the abnormal liver regeneration"; this would improve the microenvironment of liver regeneration, which is also a mechanism by which liver cancer may be prevented or treated. 展开更多

BACKGROUND Calculus bovis(CB),used in traditional Chinese medicine,exhibits anti-tumor effects in various cancer models.It also constitutes an integral component of a compound formulation known as Pien Tze Huang,which is indicated for the treatment of liver cancer.However,its impact on the liver cancer tumor microenvironment,particularly on tumor-associated macrophages(TAMs),is not well understood.AIM To elucidate the anti-liver cancer effect of CB by inhibiting M2-TAM polarization via Wnt/β-catenin pathway modulation.METHODS This study identified the active components of CB using UPLC-Q-TOF-MS,evaluated its anti-neoplastic effects in a nude mouse model,and elucidated the underlying mechanisms via network pharmacology,transcriptomics,and molecular docking.In vitro assays were used to investigate the effects of CB-containing serum on HepG2 cells and M2-TAMs,and Wnt pathway modulation was validated by real-time reverse transcriptase-polymerase chain reaction and Western blot analysis.RESULTS This study identified 22 active components in CB,11 of which were detected in the bloodstream.Preclinical investigations have demonstrated the ability of CB to effectively inhibit liver tumor growth.An integrated approach employing network pharmacology,transcriptomics,and molecular docking implicated the Wnt signaling pathway as a target of the antineoplastic activity of CB by suppressing M2-TAM polarization.In vitro and in vivo experiments further confirmed that CB significantly hinders M2-TAM polarization and suppresses Wnt/β-catenin pathway activation.The inhibitory effect of CB on M2-TAMs was reversed when treated with the Wnt agonist SKL2001,confirming its pathway specificity.CONCLUSION This study demonstrated that CB mediates inhibition of M2-TAM polarization through the Wnt/β-catenin pathway,contributing to the suppression of liver cancer growth. 展开更多

In this editorial,we review the article by Liu et al published in the World Journal of Gastrointestinal Surgery investigating the efficacy and safety of immunotherapy in patients with gastric cancer(GC)and liver metastasis.GC,the fifth most com-monly diagnosed malignancy worldwide,presents a significant challenge due to its multifactorial etiology and a grim prognosis for unresectable or recurrent cases.The advent of immune checkpoint inhibitors(ICIs)has revolutionized oncology;yet liver metastasis has been associated with reduced response rates,progression-free survival,and overall survival in various malignancies.The Che-ckMate-649 and KEYNOTE-859 trials demonstrated promising results with ICIs in advanced GC,particularly in patients with liver metastasis.However,a meta-analysis of liver metastatic solid tumors revealed worse outcomes with ICIs,high-lighting the need for further investigation.While combined therapies,including ICIs with local treatments,show promise in improving outcomes,the nuanced landscape of ICIs in liver metastatic GC necessitates continued research for robust conclusions.The current contradictions in the literature underscore the impor-tance of cautious interpretation and the exploration of tailored approaches to enhance clinical efficacy in this challenging patient population. 展开更多

In this editorial we comment on the review by Wang et al published in the recent issue of the World Journal of Gastroenterology in 2023.Small extracellular vesicles(exosomes)play important roles in the tumor microenvironment.In this review,the authors introduce the following points:(1)The composition and function of exosomal microRNAs(miRNAs)of different cell origins in hepatocellular carcinoma(HCC);(2)the crosstalk between exosomal miRNAs from stromal cells and immune cells in the tumor microenvironment and the progression of HCC;and(3)the potential applicability of exosomal miRNAs derived from mesenchymal stem cells in the treatment of HCC.In addition,the potential applicability of exosomal miRNAs derived from mesenchymal stem cells in the treatment of HCC was introduced.In this review,the authors give us an overview of the exosomal RNA and summarize the function of exosomal RNA in HCC,which provides a deeper understanding of exosomal miRNAs to the readers. 展开更多

On the basis of real-world clinical data,the study aimed to explore the effect and mechanisms of the treatment plan of“traditional Chinese medicine(TCM)regulating liver regeneration.”A total of 457 patients with HBV-related liver failure were retrospectively collected.The patients were divided into three groups:the modern medicine control group(MMC group),patients treated with routine medical treatment;the control group combining traditional Chinese and Western medicine(CTW),patients treated with routine medical treatment plus the common TCM formula;and the treatment group of“TCM regulating liver regeneration”(RLR),patients treated with both routine medical treatment and the special TCM formula of RLR.After 8 weeks of treatment,the mortality of patients in the RLR group(12.31%)was significantly lower than those in the MMC(50%)and CTW(29.11%)groups.Total bilirubin level significantly decreased and albumin increased in the RLR group when compared with the MMC and CTW groups(P<0.05).In addition,there were significant differences in the expression of several cytokines related to liver regeneration in the RLR group compared with the MMC group.RLR treatment can decrease jaundice,improve liver function,and significantly reduce the mortality in patients with HBV-related liver failure.The mechanism may be related to the role of RLR treatment in influencing cytokines related to liver regeneration. 展开更多

Since the beginning of 2017, Chinese Journal of Cancer has published a series of important questions in cancer research and clinical oncology to promote cancer research and accelerate collaborations. In this article, 10 questions are presented as followed. Question 76. How to develop effective therapeutics for cancer cachexia? Question 77.How can we develop preclinical animal models to recapitulate clinical situations of cancer patients for more effective anti-cancer drug development? Question 78. How can we develop novel effective therapeutics for pancreatic cancer and hepatocellular carcinoma? Question 79. What are the true beneficial mechanisms of antiangiogenic therapy in cancer patients? Question 80. How to approach the complex mechanisms of interplay among various cellular and molecular components in the tumor microenvironment? Question 81. Can tissue oxygenation improve the efficacy of conventional chemotherapy on cancer? Question 82. Can tissue oxygenation improve the efficacy of radiotherapy on digestive system tumors including liver cancer? Question 83. Can we integrate metabolic priming into multimodal management of liver cancer? Question 84. Has the limit of anti-androgen strategy in prostate cancer treatment been reached by the new generation of anti-androgen drugs? Question 85. Can we identify individuals with early-stage cancers via analyzing their clinical and non-clinical information collected from social media, shopping history, and clinical, pathological, and molecular traces? 展开更多
