Abstract
Dendritic cells (DCs), as the most important antigen-presenting cells, play a crucial role in T cell activation. The latest research showed that inhibition of the mammalian target of rapamycin (mTOR) could enhance DCs maturation, promoting antigen presentation. Matrine has been identified as one of the key alkaloids isolated from the roots of Sophora flavescens. In present study, we combined matrine and mTOR inhibitor KU0063794 to observe the DCs functions, especially the antigen presentation ability. DCs were activated by phosphate-buffered saline (PBS), lipopolysaccharide (LPS), LPS+KU0063794, LPS+Matrine, and LPS+KU0063794+Matrine. The surface markers in DCs, proliferation of T cells and cytokines were detected by flow cytometry, cell counting kit-8 (CCK-8) and enzyme-linked immunosorbent assay (ELISA), respectively. The lactate dehydrogenase (LDH) release test was used to detect the antitumor efficacy. The tumor growth curves were plotted by calculating tumor volume. The apoptosis was detected by Terminal-deoxynucleoitidyl Transferase-Mediated Nick End Labeling (TUNEL) method. Matrine combined with KU0063794 could enhance the maturity of DCs, T cells proliferation and cytokines secretion (P < 0.05). The cytotoxic T lymphocytes (CTL) killing efficacy of LPS+KU0063794+Matrine group was higher than other groups (P < 0.05). In vivo, the tumor weights and volumes in LPS+KU0063794+Matrine group were lower than other groups. The detections of tumor apoptosis were increased in LPS+KU0063794+Matrine group (P < 0.05). DC vaccine with mTOR inhibitor and matrine could significantly improve the efficacy of antitumor immunity in vitro and vivo. These findings illustrated that mTOR inhibitor and matrine, as two immunomodulators, could enhance DC activation and differentiation.

Abstract
As The main effective monomer of the traditional Chinese medicine Sophora flavescens Ait, matrine has a broad scope of pharmacological activities such as anti-tumor, anti-inflammatory, analgesic, anti-fibrotic, anti-viral, anti-arrhythmia, and improving immune function. These actions explain its therapeutic effects in various types of tumors, cardiopathy, encephalomyelitis, allergic asthma, rheumatoid arthritis (RA), osteoporosis, and central nervous system (CNS) inflammation. Evidence has shown that the mechanism responsible for the pharmacological actions of matrine may be via the activation or inhibition of certain key molecules in several cellular signaling pathways including the phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/AKT/mTOR), transforming growth factor-β/mothers against decapentaplegic homolog (TGF-β/Smad), nuclear factor kappa B (NF-κB), Wnt (wingless/ integration 1)/β-catenin, mitogen-activated protein kinases (MAPKs), and Janus kinase/signal transducer and activator of transcription (JAK/STAT) signaling pathways. This review comprehensively summarizes recent studies on the pharmacological mechanisms of matrine to provide a theoretical basis for molecular targeted therapies and further development and utilization of matrine.

Abstract
Matrine, a major alkaloid isolated from the traditional Chinese herb Sophora flavescens, has been used clinically to treat breast cancer in China. However, the effects of matrine on apoptosis and autophagy in breast cancer cells remain unclear. In the present study, the anti‑breast cancer capacity of matrine was evaluated and its role in regulating apoptosis and autophagy in vitro was investigated. Matrine significantly inhibited the growth of MCF‑7 cells. In addition, Hoechst 33342 staining and Annexin V/propidium iodide staining demonstrated that incubation with matrine induced apoptosis in MCF‑7 cells. Furthermore, matrine induced autophagy in MCF‑7 cells, manifesting as an accumulation of light chain 3 II and downregulation of p62. Additionally, matrine suppressed AKT and mammalian target of rapamycin (mTOR) phosphorylation, indicating that the AKT/mTOR pathway is involved in matrine‑induced apoptosis and autophagy. Overall, the results of the present study indicated that matrine possesses anti‑breast cancer activity by providing protective autophagy via inhibition of the AKT/mTOR pathway. These findings indicated that matrine may be a promising candidate for drug development targeting breast cancer.

Abstract
Autophagy, an intricate response to nutrient deprivation, pathogen infection, Endoplasmic Reticulum (ER)-stress and drugs, is crucial for the homeostatic maintenance in living cells. This highly regulated, multistep process has been involved in several diseases including cardiovascular and neurodegenerative diseases, especially in cancer. It can function as either a promoter or a suppressor in cancer, which underlines the potential utility as a therapeutic target. In recent years, increasing evidence has suggested that many natural products could modulate autophagy through diverse signaling pathways, either inducing or inhibiting. In this review, we briefly introduce autophagy and systematically describe several classes of natural products that implicated autophagy modulation. These compounds are of great interest for their potential activity against many types of cancer, such as ovarian, breast, cervical, pancreatic, and so on, hoping to provide valuable information for the development of cancer treatments based on autophagy.

Abstract
Parkinson's disease (PD) is one of the most prevailing aging diseases around the world. The present study was to investigate the potential effect of hydrogen sulfide (H2S) and silent mating type information regulation 2 homolog 1 (SIRT1) in MPP~+ induced SH-SY5Y cells and its underlying mechanisms in PD. SH-SY5Y cells were induced by MPP~+ and treated with the H2S donor NaHS to detect the effect of H2S on the molecular behaviors of MPP~+ induced SH-SY5Y cells. NaHS reduced the apoptosis rate and expressions of MDA, 4-HNE and p62, while increased cell viability, autophagy flux and expressions of LC3 II/I and Beclin1 in MPP~+ induced SH-SY5Y cells. Then, levels of autophagy-related proteins and inflammation-related proteins (TNF-α, IL-Iβ) were detected, indicating that Chloroquine and Sirtinol reversed the protective effect of H2S on SH-SY5Y cells induced by MPP~+. We further explored the particular function of H2S, SH-SY5Y cells treated with MPP~+, NaHS chloroquine, and SIRT1 inhibitor (Sirtinol). The results showed that H2S increased SIRT1 expression and sulfhydration. Finally, a PD mouse model verified the above results. In a word, H2S ameliorated SIRT1 activity through acceleration of SIRT1 sulfhydration to increase the autophagy flux and attenuate damage of SH-SY5Y cells induced by MPP~+. H2S and SIRT1 activator might be a target in the treatment of PD patients.

Abstract
Matrine (MAT) is an alkaloid in the dried roots of Sophora flavescens. The antitumor activity has been testified in colon cancer. Howbeit, the latent mechanism is still indistinct. The research probed the antitumor mechanism of MAT in colon cancer cells. MAT (0.25, 0.5, 0.75, 1, and 1.25 mM) was utilized to stimulate SW480 and SW620 cells for 24, 48, and 72 hr. Cell viability, apoptosis, cell cycle, and the correlative proteins were assessed via Cell Counting Kit-8, flow cytometry, and Western blot. microRNA-22 (miR-22) in MAT-treated or miR-22-silenced cells was estimated via real-time quantitative polymerase chain reaction. The functions of miR-22 inhibition were reassessed. Western blot was conducted for quantifying β-catenin, MEK, and ERK. Luciferase reporter assay was done for confirming the targeting relationship between miR-22 and ERBB3 or MECOM. MAT prohibited cell viability, accelerated apoptosis, and triggered cells cycle stagnation at G0/G1 phase. Additionally, miR-22 was elevated by MAT; meanwhile, the influences of MAT were all inverted by miR-22 inhibitor. MAT enhanced the expression of miR-22, thereby obstructing Wnt/β-catenin and MEK/ERK pathways. miR-22 had a potential to target mRNA 3'UTR of ERBB3 and MECOM. These discoveries manifested that MAT could evoke colon cancer cell apoptosis and G0/G1 cell cycle arrest via elevating miR-22.

Abstract
Metastasis can be a fatal step in breast cancer progression. Effective therapies are urgently required due to the limited therapeutic options clinically available. The aim of the present study was to investigate the effect of matrine (MAT), a traditional Chinese medicine, on the proliferation and migration of human breast cancer cells and its underlying mechanisms of action. The proliferation of MDA-MB-231 cells was inhibited and apoptosis was induced following treatment with MAT, as determined by MTT and Annexin-V-FITC/PI assays. Western blot analysis was used to detect the LC-3II/I levels and the results suggested that tumor autophagy is involved in the anti-tumor activity of MAT. To the best of our knowledge, this is the first study to report that MAT inhibits MDA-MB-231 and MCF-7 cell motility, potentially by targeting integrin β1 (ITGB1) and epithelial-to-mesenchymal transition (EMT), as indicated by Transwell® and siRNA interference assays. In conclusion, ITGB1 and EMT are involved in MAT-induced breast carcinoma cell death and the inhibition of metastasis. This may lead to the development of novel compounds for the treatment of breast cancer metastasis.

Abstract
Osteosarcoma is an aggressive bone cancer that frequently metastasizes to the lungs. The cytotoxicity of most chemotherapeutics and targeted drugs in the treatment of osteosarcoma is partially lessened. Furthermore, there is a poor response to current chemo- and radiotherapy for both primary lesions and pulmonary metastases of osteosarcoma. There is a clear need to explore promising drug candidates that could improve the efficacy of osteosarcoma treatment. Autophagy, a dynamic and highly conserved catabolic process, has dual roles in promoting cell survival as well as cell death. The role of autophagy has been investigated extensively in different tumor types, and a growing body of research has highlighted the potential value of using autophagy in clinical therapy. Here, we address significant aspects of autophagy in osteosarcoma, including its functions, modulation, and possible therapeutic applications.

Abstract
Background H2BK12ac is an important histone acetylation pattern of H2B, which has been reported in several cancers. However, whether H2BK12ac joins in Ras-ERK1/2 activation-induced osteosarcoma (OS) cell behaviors remain unclear. The study explored this peradventure and revealed the underlying mechanism. Methods MG-63 cells were transfected with pEGFP-N1, pEGFP-RasWT and pEGFP-K-RasG12V/T35S, H2BK12ac and ERK1/2 expression levels were analyzed by Western blot. Effects of H2BK12ac on cell viability, migration, colony formation and cell cycle were investigated by MTT, Transwell, soft-agar colony formation and flow cytometry assays. RT-qPCR and ChIP were performed to study the effect of H2BK12ac and CBP on ERK1/2-downstream gene transcriptions. Results H2BK12ac was specifically down-regulated by Ras-ERK1/2 activation in MG-63 cells. Down-regulated H2BK12ac participated in regulating cell proliferation and migration of MG-63 cells, meanwhile, affected the transcription of ERK1/2-downstream genes. Additionally, silence of HDAC1 up-regulated H2BK12ac expression, and inhibited the promoting effect of Ras-ERK1/2 on MG-63 cells' proliferation, migration and RNA expression levels of ERK1/2-downstream genes. Further, the degradation of CBP mediated by MDM2 was discovered to be linked to Ras-ERK1/2 activation-induced H2BK12ac down-regulation. Conclusion These findings from the study demonstrated that Ras-ERK1/2 signaling could promote the development of OS via regulating H2BK12ac through MDM2-mediated CBP degradation.

Abstract
OBJECTIVE To investigate the inhibitory effect of matrine on the proliferation of human non-small cell lung cancer (NSCLC) and explore the possible molecular mechanism. METHODS Cultured human NSCLC A549 cells were treated with 0.4, 0.8, 1.2, 1.6, and 2.0 g/L matrine for 24, 48 or 72 h. CCK-8 assay was used for measuring the changes in A549 cell viability. The morphological changes of the cells were observed under a fluorescence microscope, and flow cytometry was employed for analyzing the cell apoptosis. The effects of matrine and the PI3K specific inhibitor LY294002 (10 nmol/L) on AKT pathway and autophagy-related proteins in A549 cells were investigated using Western blotting. RESULTS Matrine significantly inhibited the proliferation of A549 cells in a time- and dose-dependent manner (P < 0.05). At the concentration of 1.6 g/L or higher, matrine caused obvious cell shrinkage and fragmentation and significantly increased floating cells; autophagy vacuoles could be observed in the cells after acridine orange staining. Within the concentrations range of 0.8-1.6 g/L, matrine time- and dosedependently increased the cell apoptosis. Treatment of the cells with 1.6 g/L matrine and 10 nmol/L LY294002 resulted in significantly lowered expressions of p-AKT and p-mTOR proteins and increased the expression of light chain 3B (LC 3B), an autophagy-related protein, as compared with those in the control cells (P < 0.05). CONCLUSIONS We demonstrate that matrine inhibits the proliferation and induces autophagy and apoptosis of A549 cells by deactivating AKT pathway, suggesting the potential of matrine as an anti-cancer agent for lung cancer.

Abstract
Neuropathic pain is a well‐known type of chronic pain caused by damage to the nervous system. Autophagy is involved in the development and/or progression of many diseases, including neuropathic pain. Emerging evidence suggests that metformin relieves neuropathic pain in several neuropathic pain models; however, metformin's cellular and molecular mechanism for pain relief remains unknown. In this study, we investigated the therapeutic effects of metformin on pain relief after spinal nerve ligation (SNL) and its underlying mechanism of autophagy regulation. Behavioural analysis, histological assessment, expression of c‐Fos and molecular biological changes, as well as ultrastructural features, were investigated. Our findings showed that the number of autophagosomes and expression of autophagy markers, such as LC3 and beclin1, were increased, while the autophagy substrate protein p62, as well as the ubiquitinated proteins, were accumulated in the ipsilateral spinal cord. However, metformin enhanced the expression of autophagy markers, while it abrogated the abundance of p62 and ubiquitinated proteins. Blockage of autophagy flux by chloroquine partially abolished the apoptosis inhibition and analgesic effects of metformin on SNL. Taken together, these results illustrated that metformin relieved neuropathic pain through autophagy flux stimulation and provided a new direction for metformin drug development to treat neuropathic pain.

Abstract
Corilagin is a component of Phyllanthus urinaria extract and has been found of possessing anti‐inflammatory, anti‐oxidative, and anti‐tumour properties in clinic treatments. However, the underlying mechanisms in anti‐cancer particularly of its induction of cell death in human breast cancer remain undefined. Our research found that corilagin‐induced apoptotic and autophagic cell death depending on reactive oxygen species (ROS) in human breast cancer cell, and it occurred in human breast cancer cell (MCF‐7) only comparing with normal cells. The expression of procaspase‐8, procaspase‐3, PARP, Bcl‐2 and procaspase‐9 was down‐regulated while caspase‐8, cleaved PARP, caspase‐9 and Bax were up‐regulated after corilagin treatment, indicating apoptosis mediated by extrinsic and mitochondrial pathways occurred in MCF‐7 cell. Meanwhile, autophagy mediated by suppressing Akt/mTOR/p70S6K pathway was detected with an increase in autophagic vacuoles and LC3‐II conversion. More significantly, inhibition of autophagy by chloroquine diphosphate salt (CQ) remarkably enhanced apoptosis, while the caspase inhibitor z‐VAD‐fmk failed in affecting autophagy, suggesting that corilagin‐induced autophagy functioned as a survival mechanism in MCF‐7 cells. In addition, corilagin induced intracellular reactive oxygen species (ROS) generation, when reduced by ROS scavenger NAC, apoptosis and autophagy were both down‐regulated. Nevertheless, in SK‐BR3 cell which expressed RIP3, necroptosis inhibitor Nec‐1 could not alleviate cell death induced by corilagin, indicating necroptosis was not triggered. Subcutaneous tumour growth in nude mice was attenuated by corilagin, consisting with the results in vitro. These results imply that corilagin inhibits cancer cell proliferation through inducing apoptosis and autophagy which regulated by ROS release.

Abstract
Traditional cancer therapy is mainly targeting on enhancing cell apoptosis, however, it is well established that many cancer cells are chemo-resistant and defective in apoptosis induction. Therefore, it may have important therapeutic implications to exploit some novel natural compounds based on non-apoptotic programmed cell death. Currently, accumulating evidence shows that the compounds from nature source can induce non-apoptotic programmed cell death in cancer cells, and therefore these natural compounds have gained a great promise for the future anticancer therapeutics. In this review, we will concentrate our efforts on the latest developments regarding major forms of non-apoptotic programmed cell death--autophagic cell death, necroptosis, ferroptosis, pyroptosis, glutamoptosis and exosome-associated cell death. Our increased understanding of the role of natural compounds in regulating non-apoptotic programmed cell death will hopefully provide prospective strategies for cancer therapy.

Abstract
Autophagy is a critical lysosomal pathway that degrades cytoplasmic components to maintain cell homeostasis and provide substrates for energy metabolism. A study revealed that heme oxygenase-1 (HO-1)-transduced bone marrow-derived mesenchymal stem cells (BM-MSCs) could protect 50% reduced-size liver transplantation (RSLT) in a rat model. However, the mechanisms remain mostly unknown. The aim of the present study was to explore the effects and related mechanism of autophagy on the protection conferred by HO-1-transduced BM-MSCs (HO-1/BM-MSCs) on 50% RSLT in a rat model. The authors established an acute rejection model following 50% RSLT in rats, with recipients divided into three groups receiving treatment with BM-MSCs, HO-1/BM-MSCs or normal saline (NS) injected through the dorsal penile vein. Transplanted liver tissues at 0, 1, 3, 5, 7, 10 and 14 days following transplantation were acquired for further analysis. The results indicated that the expression of autophagy-related proteins LC3 and Beclin-1 increased, the levels of ERK and p-ERK increased, and the levels of mammalian target of rapamycin (mTOR) and p-mTOR decreased in the HO-1/BM-MSCs. These observations indicated that autophagy is involved in the protective effects of HO-1/BM-MSCs on liver grafts following RSLT, possibly via upregulation of autophagy-related proteins through the ERK/mTOR signaling pathway.

Abstract
Matrine, extracted from the Chinese traditional medicine Sophorae flavescentis, has been demonstrated to exhibit antitumor effects on numerous types of cancer in vivo and in vitro with low toxicity. However, its antitumor mechanism in rhabdomyosarcoma (RMS) cells remains unclear. In the present study, the antitumor effects of matrine and its underlying mechanisms in RMS were investigated in vitro. The results demonstrated that matrine inhibited cell proliferation, migration and invasion, and induced apoptosis of RMS cells in a dose-dependent manner. Furthermore, the expression levels of phosphorylated mitogen-activated protein kinase (p-MEK) and phosphorylated extracellular signal-regulated kinase (p-ERK) significantly decreased in RMS cells following matrine treatment. In addition, the apoptotic effects of matrine in RMS cells were partially inhibited upon MEK1 overexpression and enhanced upon combined treatment with an ERK inhibitor (U0126). In addition, the ratio of apoptosis regulator BCL-2/BAX significantly decreased following matrine treatment. In conclusion, these findings indicate that matrine inhibits cell proliferation and induces the apoptosis of RMS cells by suppressing the ERK signaling pathway, and may be a novel effective candidate for the treatment of patients with RMS.

Abstract
Matrine is a traditional Chinese herbal medicine that shows antitumor efficacy for many types of cancer. The present study evaluated the antitumor efficacy of matrine on cervical cancer and to investigate the underlying mechanisms. We performed MTT assays, and in vitro invasion and migration assays, and P1 L6 found that matrine significantly inhibited cervical cancer cell growth by inducing apoptosis, and suppressed the invasion and migration ability of cervical cancer cells in vitro in a concentration-dependent manner. Mechanistically, we found that matrine decreased the expression and activity of the extracellular matrix factors, matrix metalloproteinases-2 (MMP-2) and MMP-9 via the suppression of p38 signaling pathway. In addition, when cervical cancer cells were grown as xenografts in nude mice, intraperitoneal (i.p.) injection of matrine induced a significant dose-dependent decrease in tumor growth. Taken together, these findings suggest that a potential mechanism by which matrine inhibits the growth and metastasis of cervical cancer through downregulating the p38 signaling pathway.
