Efficacy of Huaier granule in patients with breast cancer

Huaier enhances the tumor-killing effect and reverses gemcitabine-induced stemness by suppressing FoxM1

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.

Effect of Huaier granule on prognosis of breast cancer: A single-center propensity score matching retrospective study

BACKGROUND

Huaier granule is an important medicinal fungus extract widely used in cancer treatment. Previous retrospective studies have reported its effectiveness in breast cancer patients, but the imbalanced baseline characteristics of participants could have biased the results. Therefore, this retrospective study aimed to examine the efficacy of Huaier granule on the prognosis of breast cancer patients.

METHODS

In this single-center cohort study, breast cancer patients diagnosed and treated at the Guangdong Provincial Hospital of Chinese Medicine between 2009 and 2017 were selected. The data were retrospectively analyzed and divided into two groups according to whether the patients received Huaier granules. The propensity score matching (PSM) method was used to eliminate selection bias. The disease-free survival (DFS) and overall survival (OS) for these groups were compared using the Kaplan-Meier method and the Cox regression.

RESULTS

This study included 214 early invasive breast cancer patients, 107 in the Huaier group and 107 in the control group. In the Kaplan-Meier analysis, the 2-year and 5-year DFS rates were significantly different in the Huaier group and control group (hazard ratio [HR], 0.495; 95% confidence interval [CI], 0.257-0.953; P = 0.023). The 2-year and 5-year OS rates were also significantly different (HR, 0.308; 95% CI, 0.148-0.644; P = 0.001). On multivariable Cox regression, Huaier granule was associated with improved DFS (HR, 0.440; 95% CI, 0.223-0.868; P = 0.018) and OS (HR, 0.236; 95% CI, 0.103-0.540; P = 0.001).

CONCLUSION

In this retrospective study, Huaier granules improved the DFS and OS of early invasive breast cancer patients, providing real-world evidence for further prospective studies on treating breast cancer with Huaier granules.

Molecular mechanisms and therapeutic applications of huaier in breast cancer treatment

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.

Effects of adjuvant huaier granule therapy on survival rate of patients with hepatocellular carcinoma

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.

Huaier granule prolongs overall survival after curative resection of hepatocarcinoma carcinoma: A propensity score analysis

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.

The natural medicinal fungus Huaier promotes the anti-hepatoma efficacy of sorafenib through the mammalian target of rapamycin-mediated autophagic cell death

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.

Huaier Extract Induces Apoptosis in Hepatoblastoma Cells Via the MEK/ERK Signaling Pathway

BACKGROUND/AIM

Huaier extract, whose main active constituent is the proteoglycan, has anti-tumor activity in several types of malignancies. In this study, we aimed to elucidate the effect of Huaier extract in hepatoblastoma cells.

MATERIALS AND METHODS

The effect of Huaier extract on the proliferation of human hepatoblastoma cell lines HepG2 and HuH-6, was examined.

RESULTS

Incubation with Huaier extract resulted in a marked, dose-dependent decrease in hepatoblastoma cell viability. Huaier extract induced S phase arrest in hepatoblastoma cells and upregulated the expression of the cell cycle related proteins cyclin D1 and cyclin D3. It also induced apoptosis in hepatoblastoma cells. Additionally, it significantly suppressed the activity of p-ERK and p-MEK.

CONCLUSION

Huaier extract inhibits proliferation, and induces cell apoptosis and cell cycle arrest via the MEK-ERK pathway in hepatoblastoma cells. Huaier extract may act as a complementary agent for treating hepatoblastoma.

Huaier increases the antitumor effect of gemcitabine on pancreatic cancer in vitro and in vivo

BACKGROUND

Pancreatic cancer has a high degree of malignancy and poor prognosis. As the first-line chemotherapy drug for pancreatic cancer, gemcitabine is widely used but is limited in its efficacy due to the development of chemoresistance. Huaier is a traditional Chinese medicine with anticancer effects. This present study explored the antitumor effect of gemcitabine combined with Huaier on pancreatic cancer in vitro and in vivo.

METHODS

After treatment with gemcitabine combined with Huaier in PaTu8988 pancreatic cancer cells, including 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) assay, wound healing, and Transwell invasion in vitro assays were performed to investigate the proliferation, migration and invasion of cells, respectively. The apoptotic rate of cells was detected by propidium iodide-annexin V staining and flow cytometry. In vivo PaTu8988 pancreatic cancer xenograft and tail vein injection into lung metastasis nude mice models were used to determine the tumor growth and lung metastasis efficiency.

RESULTS

Huaier could not only inhibit the proliferation, migration, and invasion of cancer cells, but could also induce the apoptosis of pancreatic cancer in vitro and suppress tumor growth and lung metastasis in vivo. It further significantly increased the tumor suppressing effects of gemcitabine, and combined use of the two drugs exhibited a synergistic effect.

CONCLUSIONS

Our present study concluded that Huaier was capable of enhancing the antitumor effect of gemcitabine in pancreatic cancer in vitro and in vivo. Therefore, Huaier may be a potential drug to increase the therapy sensitivity of gemcitabine and improve the prognosis of pancreatic cancer patients.

Huaier Extract Inhibits Prostate Cancer Growth via Targeting AR/AR-V7 Pathway

The androgen receptor (AR) plays a pivotal role in prostatic carcinogenesis, and it also affects the transition from hormone sensitive prostate cancer (HSPC) to castration-resistant prostate cancer (CRPC). Particularly, the persistent activation of the androgen receptor and the appearance of androgen receptor splicing variant 7 (AR-V7), could partly explain the failure of androgen deprivation therapy (ADT). In the present study, we reported that huaier extract, derived from officinal fungi, has potent antiproliferative effects in both HSPC and CRPC cells. Mechanistically, huaier extract downregulated both full length AR (AR-FL) and AR-V7 mRNA levels via targeting the SET and MYND domain-containing protein 3 (SMYD3) signaling pathway. Huaier extract also enhanced proteasome-mediated protein degradation of AR-FL and AR-V7 by downregulating proteasome-associated deubiquitinase ubiquitin-specific protease 14 (USP14). Furthermore, huaier extract inhibited AR-FL/AR-V7 transcriptional activity and their nuclear translocation. More importantly, our data demonstrated that huaier extract could re-sensitize enzalutamide-resistant prostate cancer cells to enzalutamide treatment in vitro and in vivo models. Our work revealed that huaier extract could be effective for treatment of prostate cancer either as monotherapy or in combination with enzalutamide.

p-MEK expression predicts prognosis of patients with adenocarcinoma of esophagogastric junction (AEG) and plays a role in anti-AEG efficacy of Huaier

The incidence rate of adenocarcinoma of the esophagogastric junction (AEG) is increasing worldwide with poor prognosis and unclear pathogenesis. Trametes robiniophila Murr. (Huaier), a traditional Chinese medicine has been used in the clinical treatment of a variety of solid tumors, including AEG. However, its anticancer components and molecular mechanisms are still unclear. In our previous studies, we have found that Huaier n-butanol extract (HBE) shows the most potent anticancer activity among different extracts. In the present study, we aimed to investigate the clinical relevance of p-MEK expression in AEG patients and the role of the MEK/ERK signaling pathway in the anti-AEG efficacy of HBE in vitro and in vivo. We herein demonstrate that p-MEK expression in AEG tissues was significantly higher than that in paracancerous tissues and correlated with a poor prognosis in AEG patients. We further found that HBE inhibited the colony formation, migration, and invasion in AEG cell lines in a concentration-dependent manner in vitro. HBE also suppressed the growth of AEG xenograft tumors without causing any host toxicity in vivo. Mechanistically, HBE caused the inactivation of the MEK/ERK signaling pathway by dephosphorylating MEK1 at S298, ERK1 at T202, and ERK2 at T185 and modulating the expression of EMT-related proteins. In summary, our results demonstrate that the high expression of p-MEK may be an independent factor of poor prognosis in patients with AEG. The clinically used anticancer drug Huaier may exert its anti-AEG efficacy by inhibiting the MEK/ERK signaling pathway.

Anti-tumor effect of Huaier extract against neuroblastoma cells in vitro

Huaier extract, the main active constituent proteoglycan, has anti-tumor activity in various experimental and clinical settings. However, the potential anti-neuroblastoma and associated mechanisms have not been investigated. Therefore, in this study, we aimed to elucidate the potential role of Huaier extract in 3 human neuroblastoma cell lines. Our study demonstrated that incubation with Huaier extract resulted in a marked decrease in cell viability in a dose-dependent manner. Huaier extract induced cell cycle arrest at G0/G1 phase in neuroblastoma and decreased the cell cycle related protein expression of cyclin D3. Western blotting analysis also showed that Huaier extract induced neuroblastoma cell apoptosis and autophagy. Signaling analysis indicated that Huaier extract suppressed the MEK/ERK and mTOR signaling pathways simultaneously. In conclusion, we verify that Huaier extract causes cell proliferation inhibition, apoptosis, autophagy, and cell cycle arrest in G0/G1 phase via MEK/ERK and mTOR signaling. Huaier extract may act as a complementary agent for treating neuroblastoma.

Huaier Extractum Promotes Dendritic Cells Maturation and Favors them to Induce Th1 Immune Response: One of the Mechanisms Underlying Its Anti-Tumor Activity

Huaier, a sandy beige mushroom with anti-tumor effects, has been applied into Traditional Chinese Medicine for more than 1600 years. Previous studies showed that Huaier exerted its anti-tumor effects not only by direct action on tumor cells, but also indirectly by modulation of immune function. In the present study, we found that Huaier treatment significantly repressed tumor growth in mice with 4T1 breast cancer and resulted in significant accumulation of CD4⁺ T cells and mature dendritic cells (DCs) in the tumor microenvironment. In vitro experiments demonstrated that Huaier treatment promoted both DC2.4 and bone marrow derived DCs (BMDCs) to express costimulatory molecules, enhance production of IL-1β and IL-12p70, while it inhibited their phagocytic activities, suggesting that Huaier treatment promotes maturation of DCs. Furthermore, we found Huaier-treated DCs profoundly stimulated proliferation of alloreactive CD4⁺ T cells and drove them to differentiate into Th1 subset. Expression of PI3K, Akt, p-Akt, JNK, and p-JNK was up-regulated, while p-p38 MAPK was down-regulated in Huaier-treated BMDCs, suggesting that Huaier promotes maturation of DCs with potent ability to activate Th1 immune response via modulation of MAPK and PI3K/Akt signaling pathways. Our findings provide further evidence for the mechanisms underlying the anti-tumor activity of Huaier.

Traditional Chinese biomedical preparation (Huaier Granule) for breast cancer: a PRISMA-compliant meta-analysis

Huaier Granule, a type of traditional Chinese biomedical preparation (TCBP), is considered to be a promising adjuvant therapy for breast cancer. Although an analysis of the published literature has been performed, the exact effects and safety of Huaier Granule remains controversial. Therefore, a wide-ranging systematic search of electronic databases from which to draw conclusions was performed. Data from 27 trials, including 2562 patients with breast cancer were analyzed. The results indicated that, compared with conventional treatment alone, the combination of conventional treatment and Huaier Granule markedly improved patients’ overall response (P=0.02) and quality of life (P<0.00001), and significantly prolonged 2-year (P=0.02), 3-year (P<0.0001) and 5-year (P=0.004) overall survival rates, and 1-year (P=0.003), 2-year (P<0.00001), 3-year (P<0.00001) and 5-year (P=0.03) disease-free survival. The immune function of patients was also significantly enhanced after combined intervention treatment, indicated by clearly increased percentages of CD3⁺ (P=0.05), CD4⁺ (P<0.00001) and natural killer cells (P<0.0001), and CD4⁺/CD8⁺ ratio (P<0.00001). The incidence of myelosuppression (P=0.001) and hepatotoxicity (P=0.05) was lower in breast cancer patients treated with Huaier Granule, whereas other adverse events did not differ significantly between the two groups (P>0.05). In summary, results of this meta-analysis suggest that the combination of conventional treatment and Huaier Granule is more effective for the treatment of breast cancer than conventional treatment alone.

Trametes robiniophila Murr in the treatment of breast cancer

Breast cancer is the leading cause of cancer death among women across the world. Trametes robiniophila Murr (Huaier), a traditional herbal medicine, has been used in China to protect human health for about 1600 years. Recent years, Huaier had been proven to be effective for multiple types of malignancies. This systematic review focused on breast cancer treatment, summarizing the curative function of Huaier aqueous extract and polysaccharides in preclinical researches. Huaier could markedly inhibit breast cancer progression with low toxicity, enhance immune response and increase the sensitivity to radiation and chemotherapy. The therapeutic effect of Huaier granule in clinical studies was also included. This review amalgamated the current studies and highlighted the promising role of Huaier and its polysaccharides as complementary alternative medicine in breast cancer treatment.

XIAOPI formula inhibits the pre-metastatic niche formation in breast cancer via suppressing TAMs/CXCL1 signaling

Background

Recent findings suggested that premetastatic niche (PMN) is a prerequisite in mediating cancer metastasis. Previously we demonstrated that XIAOPI formula could inhibit breast cancer lung metastasis via inhibiting tumor associated macrophages (TAMs)-secreted CXCL1. Herein, we aimed to explore the effects of XIAOPI formula on preventing breast cancer PMN formation and its underlying molecular mechanisms.

Methods

CXCL1 expression of TAMs was detected by qPCR and Western blotting assay. The influences of XIAOPI formula on the proliferation of TAMs and 4 T1 in the co-culture system were tested by CCK8 or EdU staining. Transwell experiment was applied to determine the effects of XIAOPI formula on the invasion ability of HSPCs and 4 T1. Breast cancer xenografts were built by inoculating 4 T1 cells into the mammary pads of Balb/c mice and lung metastasis was monitored by luciferase imaging. Immune fluorescence assay was used to test the epithelial-mesenchymal transition process and PMN formation in the lung tissues. The effects of XIAOPI formula on TAMs phenotype, hematopoietic stem/progenitor cells (HSPCs) and myeloid-derived suppressor cells (MDSCs) were determined by flow cytometry.

Results

It was found that XIAOPI formula could inhibit the proliferation and polarization of M2 phenotype macrophages, and reduce CXCL1 expression in a dose-dependent manner. However, M1 phenotype macrophages were not significantly affected by XIAOPI formula. TAMs/CXCL1 signaling was subsequently found to stimulate the recruitment of c-Kit⁺/Sca-1⁺ HSPCs and their differentiation into CD11b⁺/Gr-1⁺ MDSCs, which were symbolic events accounting for PMN formation. Moreover, XIAOPI formula was effective in inhibiting HSPCs activation and suppressing the proliferation and metastasis of breast cancer cells 4 T1 induced by HSPCs and TAMs co-culture system, implying that XIAOPI was effective in preventing PMN formation in vitro. Breast cancer xenograft experiments further demonstrated that XIAOPI formula could inhibit breast cancer PMN formation and subsequent lung metastasis in vivo. The populations of HSPCs in the bone marrow and MDSCs in the lung tissues were all remarkably declined by XIAOPI formula treatment. However, the inhibitory effects of XIAOPI formula could be relieved by CXCL1 overexpression in the TAMs.

Conclusions

Taken together, our study provided preclinical evidence supporting the application of XIAOPI formula in preventing breast cancer PMN formation, and highlighted TAMs/CXCL1 as a potential therapeutic strategy for PMN targeting therapy.

Application of positive behavior management in patients after breast cancer surgery

BACKGROUND

As a radical treatment, breast cancer surgery has a positive psychological impact on most patients. However, some patients do not have a clear understanding of the disease, which requires a more scientific and comprehensive consideration during clinical intervention and are based on cognition. The positive behavior management model is based on this kind of background-derived new interventions, which can better serve the clinical rehabilitation process of patients. The positive behavior management model based on cognitive architecture is a new type of intervention derived from this background, which can better serve the clinical rehabilitation process of patients.

AIM

To analyze the influence of a positive behavior management model based on cognitive framework on the degree of hope and self-efficacy of patients with breast cancer surgery.

METHODS

Eighty-four patients with breast cancer who underwent surgical treatment in our hospital from August 2016 to December 2018 were included in the study. The patients were divided into the experimental group (n = 42) and control group (n = 42) by random number table grouping. The control group received traditional nursing intervention, while the experimental group received a positive behavior management model based on cognitive framework based on the traditional intervention of the control group. General Self-efficacy Scale, Herth Hope Scale, Self-Rating Anxiety Scale, Self-Rating Depression Scale and Cancer Patient Specific Scale were used to evaluate the two groups before and 1 wk after intervention.

RESULTS

After the intervention, self-efficacy and hope level of the experimental group were significantly higher than those of the control group (P < 0.05). The Self-Rating Anxiety Scale and Self-Rating Depression Scale scores in the experimental group were significantly lower than those in the control group (P < 0.05). There was no significant difference in the quality of life scores between the two groups before intervention (P > 0.05). The quality of life scores in all aspects in the experimental group after intervention were significantly higher than those in the control group (P < 0.05).

CONCLUSION

The positive behavior management model based on cognitive framework applied to patients with breast cancer surgery improved hope for treatment and self-efficacy, reduced negative emotion, and improved quality of life.

Huaier Suppresses Breast Cancer Progression via linc00339/miR-4656/CSNK2B Signaling Pathway

Huaier, as known as Trametes robiniophila Murr, is a traditional Chinese medicine. Various studies have demonstrated that Huaier could inhibit cancer progression and improve the prognosis of patients. In the present study, we comprehensively screened the expression profiles of lncRNAs, miRNAs, and mRNAs in Huaier-treated breast cancer cells. Using bioinformatic analysis, hub genes were identified and functionally annotated. Weighted gene coexpression network analysis was applied to construct the molecular network influenced by Huaier. Linc00339 was then found to play a critical role in Huaier-mediated cancer suppression. To validate the effects of linc00339 and identify the downstream targets, we performed in vitro and in vivo experiments. Finally, we identified that Huaier could inhibit the proliferation of breast cancer cells through modulating linc00339/miR-4656/CSNK2B signaling pathway.

The synergistic antitumor effect of Huaier combined with 5-Florouracil in human cholangiocarcinoma cells

BACKGROUND

5-Florouracil (5-FU) is a commonly used chemotherapeutic drug for cholangiocarcinoma, whereas it has unsatisfactory effect, and patients often have chemo-resistance to it. The combination of chemotherapeutic agents and traditional Chinese medicine has already exhibited a promising application in oncotherapy. Huaier extract (Huaier) has been used in clinical practice widely, exhibiting good anti-tumor effect. This paper aims to investigate the possibility of combination 5-FU and Huaier as a treatment for cholangiocarcinoma.

METHODS

A series of experiments were performed on the Huh28 cells in vitro, which involved cell proliferation, colony formation, apoptosis, cell cycle, migratory and invasive tests. Besides, western blots were also performed to examine the potential mechanism of 5-FU.

RESULTS

The combination effect (antagonism, synergy or additive) was assessed using Chou-Talalay method. Using the CCK-8 and Colony formation assay, the anti-proliferation effect of 5-FU combined with Huaier was observed. Apoptosis inducing and cell cycle arrest effect of the combination of two drugs were assessed by flow cytometry. To determine the combined treatment on cell immigration and invasion ability, wound healing and Transwell assay were performed. The above experiment results suggest that the combined 5-FU and Huaier, compared with treatment using either drug alone, exhibited stronger effects in anti-proliferation, cycle arrest, apoptosis-induced and anti-metastasis. Further, western blot results reveal that the inhibition of STAT3 and its target genes (e.g. Ki67, Cyclin D1, Bcl-2 and MMP-2) might be set as the potential therapeutic targets. Besides, the inhibition of combination treatment in proteins expression associated with proliferation, apoptosis, cell cycle and metastasis was consistent with that of previous phenotypic experiments.

CONCLUSIONS

Huaier combined with 5-FU exhibited a synergistic anti-tumor effect in Huh28 cell. Furthermore, the mechanisms might be associated with the activation and translocation of STAT3, as well as its downstream genes.
