RESUMEN
BACKGROUND: Although Huaier granules can be used as prospective anti-cholangiocarcinoma drugs, the mechanism of action of Huaier granules in cholangiocarcinoma is not clear. The anti-cholangiocarcinoma effect of Huaier granules was validated in cell line research. In vitro experiments were conducted to investigate the signalling pathways affected by Huaier in CCA cells. METHODS AND RESULTS: Real-time quantitative PCR (RTâqPCR) and Western blot analysis were performed to analyse gene expression in CCA cells. MTT assays, scratch tests, and Transwell assays were used to explore the effects on the proliferation and metastasis of CCA cells. Chromatin immunoprecipitation assays were performed to reveal the potential underlying mechanisms involved. Twist1 was upregulated in human CCA tissues. In addition, its expression levels were negatively related to FBP1 expression levels. Mechanistically, Twist1 can bind to the region of the FBP1 promoter to reduce its expression. Huaier plays an indispensable role in suppressing Twist1 expression to inhibit the Twist1/FBP1/Wnt/ß-catenin axis. Then, we verified the effect of Huaier in vitro. CONCLUSIONS: These findings suggested that Huaier granules were capable of inhibiting CCA development through regulating the Twist1/FBP1/Wnt/ß-catenin signalling axis and provided a novel orientation for the development of novel anti-CCA drugs.

This study investigates the specific mechanisms of Huaier-induced mitochondrial apoptosis in colorectal cancer. HCT116 and SW480 cells were subjected to Huaier treatment. Cell proliferation and migration capabilities were examined through CCK-8 and scratch experiments, respectively. Apoptotic cells were clarified with Annexin-PE staining. DCFH-DA staining, malondialdehyde(MDA), and glutathione(GSH) were used to evaluate the oxidative stress damage level of cells. MitoSOX and JC-1 probes were used to selectively target mitochondria reactive oxygen species(mtROS) and mitochondria membrane potential(MMP) for the evaluation of mitochondria damage. Western blot(WB) experiment was performed to determine apoptosis proteins and PINK1/Parkin pathway. Experiments reveal that in different concentrations of Huaier treatment, the proliferation and migration capabilities of HCT116 and SW480 cells were both restrained. Additionally, mitochondrial apoptosis was activated. Compared with the control group, excessive ROS in colorectal cancer cells was generated in the Huaier group, while MDA increased, and GSH decreased, indicating oxidative stress damage. mtROS increased, and MMP decreased in colorectal cancer cells treated with Huaier, indicating mitochondrial damage. WB result revealed that Huaier suppressed the PINK1/Parkin pathway, hindered the clearance of impaired mitochondria, and subsequently facilitated apoptosis. In conclusion, Huaier impairs colorectal cancer cells through oxidative stress and mitochondria damage. Furthermore, it suppressed the PINK1/Parkin pathway, promoting mitochondria apoptosis in colorectal cancer cells.

The incidence of ulcerative colitis (UC) is increasing annually, and UC has a serious impact on patients' lives. Polysaccharides have gained attention as potential drug candidates for treating ulcerative colitis (UC) in recent years. Huaier (Trametes robiniophila Murr) is a fungus that has been used clinically for more than 1000 years, and its bioactive polysaccharide components have been reported to possess immunomodulatory effects, antitumour potential, and renoprotective effects. In this study, we aimed to examine the protective effects and mechanisms of Huaier polysaccharide (HP) against UC. Based on the H2O2-induced oxidative stress model in HT-29 cells and the dextran sulphate sodium salt (DSS)-induced UC model, we demonstrated that Huaier polysaccharides significantly alleviated DSS-induced colitis (weight loss, elevated disease activity index (DAI) scores, and colonic shortening). In addition, HP inhibited oxidative stress and inflammation and alleviated DSS-induced intestinal barrier damage. It also significantly promoted the expression of the mucin Muc2. Furthermore, HP reduced the abundance of harmful bacteria Escherichia-Shigella and promoted the abundance of beneficial bacteria Muribaculaceae_unclassified, Anaerotruncus, and Ruminococcaceae_unclassified to regulate the intestinal flora disturbance caused by DSS. Nontargeted metabolomics revealed that HP intervention would modulate metabolism by promoting levels of 3-hydroxybutyric acid, phosphatidylcholine (PC), and phosphatidylethanolamine (PE). These results demonstrated that HP had the ability to mitigate DSS-induced UC by suppressing oxidative stress and inflammation, maintaining the intestinal barrier, and modulating the intestinal flora. These findings will expand our knowledge of how HP functions and offer a theoretical foundation for using HP as a potential prebiotic to prevent UC.

Objective: This study aimed to elucidate the therapeutic effects of Huaier granules on hepatocellular carcinoma (HCC) within the Milan criteria in patients who underwent microwave ablation (MWA). Materials and methods: A total of 228 patients were included, with 97 in the Huaier group and 131 in the control group. We evaluated progression-free survival (PFS), overall survival (OS), and extrahepatic metastasis survival (EMS) using Kaplan-Meier (KM) curves with a log-rank test. Propensity Score Matching (PSM) and Stabilized Inverse Probability of Treatment Weighting (IPTW) were performed to minimize selection and confounding biases. Results: Following PSM, the 1-, 3-, and 5-year PFS rates in the Huaier and control groups were 83.5% vs 70.7%, 57.7% vs 42.6%, and 43.6% vs 31.9% (p = 0.030), respectively. The 1-, 3-, and 5-year OS rates were 98.9% vs 95.6%, 83.9% vs 72.3%, and 72.2% vs 53.7% (p = 0.023), respectively. The corresponding 1-, 3-, and 5-year EMS rates were 98.9% vs 93.4%, 91.7% vs 83.7%, and 91.7% vs 78.5% (p = 0.039), respectively. Stabilized IPTW analysis of KM curves yielded results similar to those of the PSM analysis. Additionally, administering Huaier granules for at least 6 months significantly improved PFS and OS. Conclusion: Huaier granules can reduce the risk of recurrence and improve the OS of patients with HCC within the Milan criteria following MWA. Administering Huaier granules for over 6 months proved beneficial.
RESUMEN
BACKGROUND: Huaier (Trametes robiniophila Murr), a traditional Chinese medicine, is widely used in China as a complementary and alternative therapy to treat hepatocellular carcinoma (HCC). Past studies have shown that Huaier can arrest the cell cycle, promote apoptosis and inhibit the proliferation of cancer cells. However, how it regulates the metabolism of HCC is still unclear. OBJECTIVE: This study explores the metabolic-related function of Huaier in treating HCC with an in-silico approach. METHODS: A network pharmacology and bioinformatics-based approach was employed to investigate the molecular pathogenesis of metabolic reprogramming in HCC with Huaier. The compounds of Huaier were obtained from public databases. Oral bioavailability and drug likeness were screened using the TCMSP platform. The differential gene expressions between HCC and non-tumor tissue were calculated and used to find the overlap from the targets of Huaier. The enrichment analysis of the overlapped targets by Metascape helped filter out the metabolism-related targets of Huaier in treating HCC. Protein-protein interaction (PPI) network construction and topological screening revealed the hub nodes. The prognosis and clinical correlation of these targets were validated from the cancer genome atlas (TCGA) database, and the interactions between the hub nodes and active ingredients were validated by molecular docking. RESULTS: The results showed that Peroxyergosterol, Daucosterol, and Kaempferol were the primary active compounds of Huaier involved in the metabolic reprogramming of HCC. The top 6 metabolic targets included AKR1C3, CYP1A1, CYP3A4, CYP1A2, CYP17A1, and HSD11B1. The decreased expression of CYP3A4 and increased expression of AKR1C3 were related to the poor overall survival of HCC patients. The molecular docking validated that Peroxyergosterol and Kaempferol exhibited the potential to modulate CYP3A4 and AKR1C3 from a computational perspective. CONCLUSION: This study provided a workflow for understanding the mechanism of Huaier in regulating the metabolic reprogramming of HCC.
RESUMEN
BACKGROUND: Gemcitabine is the first-line chemotherapy drug that can easily cause chemotherapy resistance. Huaier is a traditional Chinese medicine and shows an antitumor effect in pancreatic cancer, but whether it can enhance the gemcitabine chemotherapeutic response and the potential mechanism remain unknown. PURPOSE: This study was performed to explore the effect of Huaier in promoting the tumor-killing effect of gemcitabine and elucidate the possible mechanism in pancreatic cancer. METHODS: Cell Counting Kit-8 assays and colony formation assays were used to detect proliferation after different treatments. Protein coimmunoprecipitation was applied to demonstrate protein interactions. Nuclear protein extraction and immunofluorescence were used to confirm the intracellular localization of the proteins. Western blotting was performed to detect cell proliferation-related protein expression or cancer stem cell-associated protein expression. Sphere formation assays and flow cytometry were used to assess the stemness of pancreatic cancer cells. The in vivo xenograft model was used to confirm the inhibitory effect under physiological conditions, and immunohistochemistry was used to detect protein expression. RESULTS: Huaier suppressed the proliferation and stem cell-like properties of pancreatic cancer cells. We found that Huaier suppressed the expression of forkhead box protein M1 (FoxM1). In addition, Huaier inhibited FoxM1 function by blocking its nuclear translocation. Treatment with Huaier reversed the stemness induced by gemcitabine in a FoxM1-dependent manner. Furthermore, we verified the above results by an in vivo study, which reached the same conclusion as those in vitro. CONCLUSION: Overall, this study illustrates that Huaier augments the tumor-killing effect of gemcitabine through suppressing the stemness induced by gemcitabine in a FoxM1-dependent way. These results indicate that Huaier can be applied to overcome gemcitabine resistance.

Background: There is basic research suggesting that Huaier granule can inhibit liver cirrhosis and hepatocellular carcinoma (HCC), but this conclusion has not been clinically verified. We analyzed the distant cancer tissue of two groups of hepatitis B virus (HBV) related HCC with/without Huaier granule, to clarify the effect of Huaier granule on liver inflammation, liver fibrosis, and postoperative recurrence. Methods: We collected clinicopathological data of HCC patients who received two surgery procedures at Mengchao Hepatobiliary Hospital of Fujian Medical University in China from January 2014 to December 2020. Patients according to taking/not taking Huaier granule after the first hepatectomy were divided into two groups, 51 patients with Huaier granule for more than 6 months after operation (Group A); 56 patients without Huaier granule (Group B). The effects on liver inflammation, fibrosis grade, and postoperative recurrence were compared between two groups. Results: The results showed that liver inflammation improved significantly in the Group A [19 (37.3%) cases improved, 31 (60.8%) cases remained unchanged, and 1 (2.0%) case deteriorated] was significantly more than that in the Group B [7 (12.5%) cases improved, 32 (57.1%) cases remained unchanged, and 17 (30.4%) cases deteriorated] (P<0.001). The liver fibrosis in the Group A [17 (33.3%) cases improved, 32 (62.7%) cases remained unchanged, and 2 (3.9%) cases deteriorated] was significantly improved in the Group B [5 (8.9%) cases improved, 45 (80.4%) cases remained unchanged, and 6 (10.7%) cases deteriorated] (P=0.005). The recurrence interval (27.0±21.2 months) in the Group A was significantly longer than that in the Group B (19.0±14.2 months) (P=0.026). Conclusions: Huaier granule can improve liver inflammation, fibrosis, and liver function and prolong the time to recurrence in HBV-related HCC. Given the high rate of postoperative recurrence and poor prognosis of HBV-related HCC, our findings may have useful clinical significance in the prevention of tumor recurrence in these patients.
RESUMEN
OBJECTIVE: The present study aims to investigate the effect of Huaier on oxaliplatin (OXA) resistance in HCT-8 colorectal cancer (CRC) cells. METHODS: Oxaliplatin-resistant HCT-8/L CRC cells were used. The Cell Counting Kit-8, western blotting, quantitative real-time polymerase chain reaction, protein extraction kit, immunofluorescence and acridine orange staining assays were used in the study. The experiment results proved that Huaier has an influence on the Wnt/ß-catenin signalling pathway, autophagy and drug resistance. The authors of the present study used chloroquine, an autophagy inhibitor and Wnt agonist 1 (a Wnt pathway agonist) to verify the present experiment. RESULTS: The results showed that Huaier can regulate autophagy, inhibit the Wnt/ß-catenin signalling pathway and reverse the drug resistance of OXA-resistant CRC cells. CONCLUSIONS: This study proved that Huaier can regulate autophagy, inhibit the Wnt/ß-catenin signalling pathway and reverse the drug resistance of OXA-resistant CRC cells.

Accumulating studies suggest that Huaier exerts anti-tumor effects through intricate mechanisms. Despite extensive research on its efficacy in lung cancer, further investigation is required to elucidate the molecular mechanism of Huaier. The involvement of long noncoding RNAs (lncRNAs) in the anti-lung cancer effects of Huaier remains unknown. In this study, we found Huaier suppressed cell viability, migration and invasion in non-small cell lung cancer (NSCLC) cells. LncRNA sequencing analysis revealed Deleted in lymphocytic leukemia 2 (DLEU2) to be significantly downregulated in Huaier-treated NSCLC cells. Furthermore, DLEU2 silencing was observed to suppress NSCLC progression, while DLEU2 overexpression attenuated the anti-tumor effects of Huaier in NSCLC, thereby promoting cell viability, migration and invasion of NSCLC. The ceRNA role of DLEU2 had been demonstrated in NSCLC, which directly interacted with miR-212-5p to rescue the repression of E74 Like ETS Transcription Factor 3 (ELF3) by this microRNA. Additionally, Huaier was found to regulate the expression of miR-212-5p and ELF3. Functionally, miR-212-5p inhibitor or ELF3 overexpression reversed the effects of DLEU2 silencing or Huaier treatment, resulting in increased colony formation, migration and invasion in NSCLC. Taken together, these results illuminate the mechanism underlying Huaier's anti-tumor effects via the DLEU2/miR-212-5p/ELF3 signaling pathway, which offers novel insights into the anti-tumor effects of Huaier and constitutes a promising therapeutic target for the treatment in NSCLC.

BACKGROUND: Combination therapy is an effective method for augmenting the efficacy of immune checkpoint inhibitors (ICIs). Huaier is a commonly used Chinese patent medicine with substantial antitumor effects. The combination of Huaier and ICIs may increase the efficacy of ICIs against hepatocellular carcinoma (HCC). METHODS: The major components of Huaier were detected by high-performance liquid chromatography-mass spectrometry. The optimal antitumor dose of Huaier was investigated in H22-bearing mice. Next, Huaier was combined with anti-CD8α antibody (Ab) or anti-PD-L1 Ab to observe the antitumor effect. The safety of these combination drugs was evaluated through blood biochemical tests and hematoxylin and eosin staining of histological sections. RT-qPCR, immunohistochemistry, flow cytometry, and transcriptome sequencing were performed to investigate the potential action mechanism of anti-PD-L1 Ab combined with Huaier against HCC. RESULTS: HPLC-MS/MS identified 333 components of Huaier, including carboxylic acids and derivatives, thienothiophenes, phenols, flavonoids and so on. Huaier exhibited significant antitumor effects, with the strongest effect noted at a dose of 4 g/kg. Huaier boosted CD8+ T cells infiltration into the tumor. Next, CD8+ T cells were depleted by with anti-CD8α Ab, and the antitumor effect of Huaier was suppressed. Flow cytometry results revealed that CD8+ T cells were reduced in the Huaier+anti-CD8α Ab group, with the antitumor effect of this group being inhibited. This indicated that CD8+ T cells were key players in the antitumor activity of Huaier. Meanwhile, Huaier inhibited microvessel density (MVD), downregulated vascular endothelial growth factor A (VEGFA), and upregulated PD-L1 in tumor tissues. Finally, Huaier combined with anti-PD-L1 Ab exhibited a greater antitumor effect in the H22-bearing mice. And the results of liver and kidney function tests and histological section analysis unveiled that the safety of these drugs was excellent. According to the transcriptome sequencing results, Huaier combined with anti-PD-L1 Ab possibly exerted anti-HCC effects through immunomodulation, immune response, and so on. CONCLUSIONS: Huaier exhibited a significant antitumor effect. It promoted CD8+ T cells infiltration, upregulated PD-L1 expression, downregulated VEGFA expression, and inhibited MVD, thereby playing a significant antitumor immunoregulatory effect. The combination of Huaier and anti-PD-L1 Ab has significant antitumor effects, and this regimen has good safety. Therefore, Huaier combined with anti-PD-L1 Ab is a promising therapeutic approach against HCC.

Vanderbylia robiniophila (Huaier in Chinese) has been used as a traditional herbal medicine in China for over 1600 years. However, the secondary metabolites of V. robiniophila have not been systematically examined. Corresponding chemical investigation in this study led to the discovery of two new compounds, (22E, 24R)-6ß, 7α-dimethoxyergosta-8(14), 22-diene-3ß, 5α-diol (1) and vanderbyliolide A (8), along with eight known ones (2-7, 9-10). Their structures were determined by extensive spectroscopic analyses and electronic circular dichroism (ECD) calculations. The tyrosinase inhibitory activity of all isolated compounds was evaluated, and compound 10 showed a potential tyrosinase inhibitory effect with an IC50 value of 60.47 ± 2.63 µM. Kinetic studies of the inhibition reactions suggested that 10 provides the inhibitory ability on tyrosinase in an uncompetitive way.
RESUMEN
Huaier (Trametes robiniophila Murr) is a medicinal fungus of traditional Chinese medicine with more than 1000 years of history of clinical application. Its remarkable anticancer activities has led to its application in treating diverse malignancies. In recent years, the immunomodulatory effects of Huaier have been uncovered and proved to be beneficial in a plethora of immune-related diseases including cancer, nephropathy, asthma, etc. In this review, we comprehensively summarized the active components of Huaier, its regulatory activities on multifaceted aspects of the immune system, its application in various clinical settings as well as toxicologic evidence. Based on currently available literature, Huaier possesses broad-spectrum regulatory activities on various components of the innate and adaptive immune system, including macrophages, dendritic cells, natural killer cells, T and B lymphocytes, etc. Versatile immunologic reactions are under the regulation of Huaier from expression of damage-associated molecular patterns, immune cell activation and maturation to cell proliferation, differentiation, antibody production, expression of cytokines and chemokines and terminal intracellular signal transduction. Moreover, some modulatory activities of Huaier might be context-dependent, typically promoting the restoration toward normal physiological status. With excellent efficacy and minimal side effects, we foresee more extensive application of Huaier for treating immune-related disorders.

Objective: Clinical trials have reported that Huaier granule inhibits the recurrence of hepatocellular carcinoma (HCC) after resection. However, its efficacy in patients at different clinical stages of HCC remains unknown. We investigated the effects of Huaier granule on the 3-year overall survival (OS) rate of patients at different clinical stages. Design: This cohort study included 826 patients with HCC, screened between January 2015 and December 2019. The patients were divided into Huaier (n = 174) and control groups (n = 652), and the 3-year OS rates were compared between the two groups. To eliminate bias caused by confounding factors, propensity score matching (PSM) was performed. We used the Kaplan-Meier method to estimate OS rate and tested the difference using the log-rank test. Results: Multivariable regression analysis revealed that Huaier therapy was an independent protective factor for 3-year survival rate. After PSM (1:2), the Huaier and control groups comprised 170 and 340 patients, respectively. The 3-year OS rate was remarkably higher in the Huaier group than in the control group (adjusted hazard ratio [aHR]: 0.36; 95% confidence interval: 0.26-0.49; p < 0.001). The aHR for Huaier use for 3-12, 12-24, and >24 months was 0.48, 0.23, and 0.16, respectively, indicating a dose-response pattern. For the 3-12-, 12-24-, and >24-month groups, the 3-year OS rate was 54.1%, 68.6%, and 90.4%, respectively. Multivariate stratified analysis confirmed that the mortality risk in Huaier users was lower than that in non-Huaier users in most subgroups. Conclusion: Adjuvant Huaier therapy improved the OS rate in patients with HCC. However, these findings require further verification through prospective clinical studies.
RESUMEN
BACKGROUND: The effectiveness and safety of huaier granules in reducing recurrence after curative resection of HCC have been confirmed, but it is unclear whether huaier granules can significantly prolong overall survival. AIM: To demonstrate the effectiveness of huaier granule for HCC after curative resection over a 5-year follow-up. METHOD: A total of 1265 HCC patients who underwent curative resection from January 2008 to January 2020 were enrolled, 1111 patients were finally enrolled according to the exclusion criteria, and the oncology outcome of Huaier granule was analyzed by propensity score matching method (PSM). RESULT: Before propensity score matching, huaier granule resulted in better 5- year overall survival (61.49% vs 54.92%, p = 0.0099) and recurrence-free survival (45.64% vs 38.42%, p = 0.0042) for HCC patients. For solitary HCC ≤30 mm, huaier granule resulted in similar 5- year recurrence-free survival (54.55% vs 50.13%, p = 0.4403), but better 5- year overall survival (82.42% vs70.08%, p = 0.0189). Similar to overall patients, huaier granule resulted in better 5- year overall survival (54.77% vs 51.37%, p = 0.1530) and recurrence-free survival (42.61% vs 35.62%, p = 0.0082) for solitary HCC >30 mm. After propensity score matching, we did confirm that huaier granules can significantly prolong overall survival by more than 5 years, the exception was recurrence-free survival in the HCC <30 mm cohort.

Breast cancer is one of the most common female malignant tumors today and represents a serious health risk for women. Although the survival rate and quality of life of patients with breast cancer are improving with the continuous development of medical technology, metastasis, recurrence, and drug resistance of breast cancer remain a significant problem. Huaier, a traditional Chinese medicine (TCM) fungus, is a type of Sophora embolism fungus growing on old Sophora stems. The polysaccharides of Trametes robiniophila Murr (PS-T) are the main active ingredient of Huaier. There is increasing evidence that Huaier has great potential in breast cancer treatment, and its anti-cancer mechanism may be related to a variety of biological activities, such as the inhibition of cell proliferation, metastasis, tumor angiogenesis, the promotion of cancer cell death, and regulation of tumor-specific immunity. There is growing evidence that Huaier may be effective in the clinical treatment of breast cancer. This review systematically summarizes the basic and clinical studies on the use of Huaier in the treatment of breast cancer, providing useful information to guide the clinical application of Huaier and future clinical studies.
RESUMEN
We studied the effects of Huaier polysaccharide (HP) in doxorubicin-induced myocardial injury in mice. The content of HP in Trametes robiniophila Murr medicinal fungus determined by the phenol-sulfuric acid method was 85.25%. In the in vitro model, the viability of H9c2 cells was significantly increased after HP treatment compared to the control, while doxorubicin (DOX) decreased this parameter. The inhibitory effect of DOX on cell viability was attenuated after HP treatment. In the in vivo model, the body weight of mice in DOX and DOX+HP groups was significantly decreased compared to the control group. ECG showed significantly elevated ST segment in the DOX group, while in the DOX+HP group, ECG was close to normal. The levels of cardiotoxicity markers cTnI and lactate dehydrogenase in the DOX+HP group were significantly lower than in the DOX group. In the DOX group, the myocardial tissue had obvious structural disorder and interfibrillar vacuoles. In the DOX+HP group, the cardiomyocytes were neatly arranged without interfibrillar vacuoles. The expression of the ferroptosis marker glutathione peroxidase 4 was increased in the DOX+HP group compared to the DOX group. Thus, our study reveals that HP attenuated DOX-induced myocardial injury in mice probably by regulating ferroptosis.

Purpose: The anti-tumour effect of Huaier has been demonstrated in a variety of tumours. Ferroptosis is a newly identified type of programmed cell death accompanied by the accumulation of reactive oxygen species (ROS) and iron in cells and plays a key role in the therapeutic process against malignant tumours. We aimed to explore the potential therapeutic role of Huaier in pancreatic cancer and uncover the relationship between Huaier and ferroptosis. Methods: CCK8 and colony formation assays were used to determine the proliferation of pancreatic cancer cells (PCs). The levels of cellular ROS were analysed by a fluorescence probe, and the accumulation of cellular iron was showed by Prussian blue staining. The autophagosomes and mitochondrial morphology were characterised by transmission electron microscopy (TEM). The levels of intracellular glutathione (GSH) and lipid peroxidation were measured by the corresponding kits. Results: The growth inhibitory effect of Huaier on PCs was concentration- and time-dependent, but this effect was significantly attenuated by ferroptosis inhibitors. In addition, Huaier effectively inhibited the GSH-GPX4 antioxidation system and resulted in the massive accumulation of ROS in PCs As shown by TEM, Huaier-treated PCs exhibited a decrease in mitochondrial cristae and a smaller mitochondrion, accompanied by an increase in autophagosomes. Indeed, we found that autophagy can induce ferroptosis in PCs and that Huaier-induced ferroptosis can be suppressed by the autophagosome inhibitor, Wortmannin. Conclusion: Huaier can activate ferroptosis by inducing autophagy in PCs.
RESUMEN
In this study, we investigated compounds of plant and mushroom origin belonging to Traditional Chinese Medicine (TCM) and to Traditional Tibetan Medicine (TTM): a sandy beige mushroom Trametes robiniophila Murr, commonly known as Huaier/TCM as well as Ershiwuwei Songshi Wan and Qiwei Honghua Shusheng Wan, which both belong to TTM. We aimed to study the efficacy of TTM and TCM in hepatocellular carcinoma (HCC) and cholangiocarcinoma (CCA) in vitro. TCM and TTM were tested either as a monotherapy, or in combination with standard therapeutics: sorafenib for HCC treatment and gemcitabine for CCA. We also discovered a protective mechanism behind the most successful therapeutic combinations. The results demonstrated that TCM and TTM inhibited the proliferation of cancer cells in a time- and dose-dependent manner. The results were compared to classical chemotherapeutics currently used in the clinic: sorafenib for HCC and gemcitabine for CCA. In HCC settings, a combination of Huaier (16 mg/ml) with half of the human plasma concentration of sorafenib, Qiwei Honghua Shusheng Wan (1 mg/ml) monotherapy as well as its combination with half or even a quarter dose of the human plasma concentration of sorafenib represented the most efficient treatments, inhibiting the growth of HCC cells more effectively than the standard therapy. The inhibitory mechanism relied on a strong induction of apoptosis. In CCA settings, Ershiwuwei Songshi Wan and Qiwei Honghua Shusheng Wan as monotherapies or in combination with very low doses of gemcitabine inhibited the growth of CCA cells more efficiently than the standard therapy. Importantly, Ershiwuwei Songshi Wan at the 8 and 16 mg/ml concentrations and Qiwei Honghua Shusheng Wan at the 4 mg/ml concentration were efficacious with gemcitabine applied at massively reduced concentrations. The protective mechanism in CCA relied on a strong induction of early and late apoptosis. Cellular senescence and necroptosis were not associated with protection against HCC/CCA. Combination therapy with TCM or TTM allowed for a dose reduction of standard chemotherapeutics. This is especially important as both chemotherapeutic drugs show strong side effects in patients. The reduction of chemotherapeutics and the synergistic effect observed while applying them in combination with TCM and TTM has strong perspectives for the clinic and patients suffering from HCC and CCA.
RESUMEN
Sorafenib (SOR) is currently the first line molecular targeting agent for advanced liver cancer therapy. Unfortunately, the insensitivity of liver cancer patients to SOR relatively limits its effectiveness. Huaier (HUA), a natural medicinal parasitic fungus found on the Sophora japonica Linn., has been widely employed as an adjuvant medication for numerous malignancies due to its potent anti-tumoral properties. This study aims to elucidate the enhancing therapeutic efficacy of HUA on SOR treatment in hepatocellular carcinoma (HCC) cells and mouse models. The CCK-8, clone formation, flow cytometry, immunofluorescence, transmission electron microscopy, western blot, bioinformatic analysis, and xenograft tumor assays were performed to evaluate the synergistic anti-hepatoma efficacy and mechanisms of HUA-SOR combination treatment on HCC cells. The results revealed combination treatment further inhibited proliferation, promoted apoptosis, enhanced autophagy of HCC cells, and suppressed the growth of transplanted tumors in mice, compared with either HUA or SOR treatment alone. For Hep3B and Huh7 cells, the optimal synergistic doses of HUA in combination with SOR were 8 mg/mL + 4 µM and 4 mg/mL + 2 µM, with combination index values of 0.646 and 0.588, respectively. Additionally, the underlying mechanisms might be related to biological processes that are mediated by mammalian target of rapamycin (mTOR). The combination treatment downregulated the protein expression levels of p-mTOR, p-p70S6K, p62, and upregulated the protein expression levels of Beclin-1 and LC3B-II. The mTOR activator MHY1485 attenuated the effect of HUA-SOR combination by inhibiting autophagy, suggesting HUA may potentiate the sensitivity of HCC cells to SOR by partially inducing mTOR-mediated autophagic cell death. These findings might provide a rationale experimental foundation for clinical applications of HUA with SOR.
