Polysaccharides from ginseng leaves inhibit tumor metastasis via macrophage and NK cell activation. Int J Biol Macromol 2017; 103:1327-1333. [PMID: 28522391 DOI: 10.1016/j.ijbiomac.2017.05.055] [Citation(s) in RCA: 52] [Impact Index Per Article: 7.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2017] [Revised: 05/03/2017] [Accepted: 05/13/2017] [Indexed: 11/24/2022]
Abstract
In this study, we purified the polysaccharide fraction (GS-P) from the leaves of Panax ginseng C.A. Meyer and analyzed its monosaccharide composition and antitumor and antimetastatic activity in vitro and in vivo. GS-P is a 10.2kDa pectic polysaccharide consisting of 15 different monosaccharides. GS-P treatment significantly inhibited metastasis in mice, in a dose-dependent manner. GS-P was not cytotoxic to colon 26-M3.1 cells and increased mouse splenocyte proliferation. Secretion of tumor necrosis factor (TNF)-α and interleukin (IL)-12 was enhanced in the peritoneal exudate macrophages (PEMs) of GS-P-treated mice. Moreover, PEMs obtained from GS-P-treated mice showed significantly higher tumoricidal activity against colon 26-M3.1 cells, and splenocytes from GS-P-treated mice significantly enhanced NK cell cytotoxicity against YAC-1 tumor cells. Pretreatment with anti-asialo GM1 (an antibody for NK cell depletion) partly suppressed the inhibitory effects of GS-P on lung metastasis. These data suggest that GS-P exhibits antimetastatic activity by promoting the activation of macrophages and NK cells.

Abstract
A mannogalactoglucan (RK2-Ab; Mw 1.8×104gmol-1) composed by Man (27.3%), Gal (24.4%) and Glc (48.3%) was extracted and characterized from Agaricus bisporus, and its biological activity was evaluated on human hepatocarcinoma cells (HepG2). The partially-O-methylated alditol acetates together with the NMR data suggest the main chain to be composed of α-d-Galp (32.8%) and β-d-Glcp (37.0%) units (1→6)-linked, with β-d-Manp (14.6%), as non-reducing end units, substituting the side chains at O-2 (α-d-Galp units; 3.3%) and O-2 and O-4 (β-d-Glcp units; 3.6%). (1→2)-linked β-d-Glcp (2.7%) and β-d-Manp (6.0%) can also be observed. RK2-Ab reduced cellular viability of HepG2 cells, by both, the MTT and lactate dehydrogenase release assays, promoted the increase of cytochrome c release and decrease of ATP content. Suggesting that the mannogalactoglucan from A. bisporus may have antitumor activity by inducing apoptosis by the mitochondrial death pathway, and could be used in cancer therapy.

Abstract
Edible and medicinal fungi (mushrooms) are widely applied to functional foods and nutraceutical products because of their proven nutritive and medicinal properties. Phellinus sensu lato is a well-known medicinal mushroom that has long been used in preventing ailments, including gastroenteric dysfunction, diarrhea, hemorrhage, and cancers, in oriental countries, particularly in China, Japan, and Korea. Polysaccharides represent a major class of bioactive molecules in Phellinus s. l., which have notable antitumor, immunomodulatory, and medicinal properties. Polysaccharides that were isolated from fruiting bodies, cultured mycelia, and filtrates of Phellinus s. l. have not only activated different immune responses of the host organism but have also directly suppressed tumor growth and metastasis. Studies suggest that polysaccharides from Phellinus s. l. are promising alternative anticancer agents or synergizers for existing antitumor drugs. This review summarizes the recent development of polysaccharides from Phellinus s. l., including polysaccharide production, extraction and isolation methods, chemical structure, antitumor activities, and mechanisms of action.

Abstract
Polysaccharides are substances that modify the biological response to several stressors. The present study investigated the antitumor activity of the soluble fraction of polysaccharides (SFP), extracted from cabernet franc red wine, in Walker-256 tumor-bearing rats. The monosaccharide composition had a complex mixture, suggesting the presence of arabinoglactans, mannans, and pectins. Treatment with SFP (30 and 60mg/kg, oral) for 14days significantly reduced the tumor weight and volume compared with controls. Treatment with 60mg/kg SFP reduced blood monocytes and neutrophils, reduced the tumor activity of N-acetylglucosaminidase, myeloperoxidase, and nitric oxide, increased blood lymphocytes, and increased the levels of tumor necrosis factor α (TNF-α) in tumor tissue. Treatment with SFP also induced the expression of the cell necroptosis-related genes Rip1 and Rip3. The antineoplastic effect of SFP appears to be attributable to its action on the immune system by controlling the tumor microenvironment and stimulating TNF-α production, which may trigger the necroptosis pathway.

Abstract
Many researches show that polysaccharides derived from fungi and plants have strong pharmacological activities such as enhancing the organism immune and anti-tumor function, and have few toxic and side effects. So the polysaccharides show a wide application prospect in the prevention and therapy of tumor. The tumor microenvironment consists of tumor cells and tumor cells' surrounding environment. The tumor microenvironment not only plays a key role in the development of tumor, but also is a potential treasure for searching new ways to treat tumor. In this review, we summarized polysaccharides' regulation effects on tumor microenvironment progression and tried to give a new theoretical basis for the exploitation of polysaccharides with anti-tumor activity.

Abstract
Hepatocellular carcinoma is one of the fatal malignancies and is considered as the third leading cause of death. Mutations, genetic modifications, dietary aflatoxins, or impairments in the regulation of oncogenic pathways may bring about liver cancer. An effective barrier against hepatotoxins is offered by gut-liver axis as a change in gut permeability and expanded translocation of lipopolysaccharides triggers the activation of Toll-like receptors which stimulate the process of hepatocarcinogenesis. Prebiotics, nondigestible oligosaccharides, have a pivotal role to play when it comes to inducing an antitumor effect. A healthy gut flora balance is imperative to downregulation of inflammatory cytokines and reducing lipopolysaccharides induced endotoxemia, thus inducing the antitumor effect.

Abstract
More than 2000 species of edible and/or medicinal mushrooms have been identified to date, many of which are widely consumed, stimulating much research on their health-promoting properties. These properties are associated with bioactive compounds produced by the mushrooms, including polysaccharides. Although β-glucans (homopolysaccharides) are believed to be the major bioactive polysaccharides of mushrooms, other types of mushroom polysaccharides (heteropolysaccharides) also possess biological properties. Here we survey the chemistry of such health-promoting polysaccharides and their reported antiobesity and antidiabetic properties as well as selected anticarcinogenic, antimicrobial, and antiviral effects that demonstrate their multiple health-promoting potential. The associated antioxidative, anti-inflammatory, and immunomodulating activities in fat cells, rodents, and humans are also discussed. The mechanisms of action involve the gut microbiota, meaning the polysaccharides act as prebiotics in the digestive system. Also covered here are the nutritional, functional food, clinical, and epidemiological studies designed to assess the health-promoting properties of polysaccharides, individually and as blended mixtures, against obesity, diabetes, cancer, and infectious diseases, and suggestions for further research. The collated information and suggested research needs might guide further studies needed for a better understanding of the health-promoting properties of mushroom polysaccharides and enhance their use to help prevent and treat human chronic diseases.

Abstract
The aim of the study was to explore whether fever-range hyperthermia (FRH) might enhance the anticancer and immunoregulatory activities of protein-bound polysaccharides (PBP), a class of fungus derived immunomodifiers used in the cancer adjuvant therapy. Blood lymphocytes and breast cancer cells (MCF-7) were cultured at 39.5°C in humidified atmosphere containing 5% CO2 for 2h. After rested at 37°C for 6h, the cells were treated with PBP extract at 100- and 300μg/ml concentration. After indicated time, the proliferative response was analyzed and cytokine mRNA expression assessment was performed by qRT-PCR. In animal model, the FRH was induced by placing rats in the Homeothermic Controller with heating blanket. Animals were heated until Tb reached 39.5°C (±0.2°C) and were maintained at this temperature for 30min. The protein-bound polysaccharides solution was injected i.p. at a dose of 100 mg/kg 6h post FRH. Twenty four hours after treatment, the blood was collected and cytokines expression analysis were performed. The results have shown that fever-range hyperthermia has an inhibitory effect on PBP extract-induced proliferative response of blood lymphocytes, as well as IL-1β and IL-6 mRNA expression. Moreover, the temperature of 39.5°C blocks PBP-induced cytotoxicity against MCF-7 cells, which correlates with significant reduction in TNF-α level. Combined treatment of rats (FRH+PBP) results in decrease of IL-1β, IL-6 and TNF-α mRNA expression in peripheral blood mononuclear cells compared to cells derived from rats treated with protein-bound polysaccharides extract alone. This study demonstrates that fever-range temperature inhibits immunostimulatory as well as anticancer effects mediated by protein-bound polysaccharides.

Abstract
A detection method using polystyrene-coated magnetic nanoparticles based extraction technique coupled to HPLC was developed for trace amount of pyrethroids residue detection in vegetable matrixes. The recoveries for five kinds of commonly used pyrethroids were in the range of 91.6%-116.2%. The sensitivity and precision of the method were satisfactory with the limits of detection and limits of quantification in the range of 0.0200-0.0392ngg(-1) and 0.072-0.128ngg(-1), respectively. The intra-day and inter-day relative standard deviations for the recoveries of the analytes were lower than 6.8% and 10.7%, respectively. The nanoparticles can be washed and recycled after use. The results indicate that the developed method was efficient, fast, economical and environmentally friendly. The method was successfully applied to detect the pyrethroids residue in ten pairs of commonly consumed organic and conventional fresh vegetables in Singapore. Pyrethroids residue was detected in four kinds of conventional vegetables and one kind of organic vegetable.

Abstract
Mushroom is a kind of fungus that has been popular for its special flavour and renowned biological values. The polysaccharide contained in mushroom is regarded as one of the primary bioactive constituents and is beneficial for health. The structural features and bioactivities of mushroom polysaccharides have been studied extensively. It is believed that the diverse biological bioactivities of polysaccharides are closely related to their structure or conformation properties. In this review, the structural characteristics, conformational features and bioactivities of several mushroom polysaccharides are summarized, and their beneficial mechanisms and the relationships between their structure and bioactivities are also discussed.

Abstract
A polysaccharide fraction, here called POP1, was purified from the leaves of Platycladus orientalis (L.) Franco by water extraction and alcohol precipitation. Physicochemical characterization indicated that POP1 had a relative molecular weight of 8.10 × 10(3) Da and consisted of rhamnose (5.74%), arabinose (12.58%), mannose (10.97%), glucose (64.96%), and galactose (6.55%). The main linkage types of POP1 consisted of (1→5)-linked α-l-Ara, (1→3)-linked α-l-Man, (1→6)-linked β-l-Rha, (1→4)-linked α-d-Glc, (1→6)-linked α-d-Glc, (1→6)-linked β-d-Gal, (1→3,6)-linked β-d-Gal, and termination with α-l-Man and α-d-Glc residues based on periodate oxidation, Smith degradation, methylation, and NMR analysis. POP1 exhibited excellent immunostimulating activity by enhancing macrophage NO, TNF-α, IL-6, and IL-12 secretion and activating related mRNA expression. Besides, POP1 showed significant anti-HBV activity through inhibiting the expression of HBsAg (IC50 = 1.33 ± 0.12 mg/mL) and HBeAg (IC50 = 1.67 ± 0.13 mg/mL) and interfering with the HBV DNA replication (IC50 = 0.80 ± 0.03 mg/mL). The present study suggested that POP1 could be used as immunoregulatory agent in functional foods for the prevention of HBV infection.

Effect of Immune-Enhancing Enteral Nutrition Enriched with or without Beta-Glucan on Immunomodulation in Critically Ill Patients. Nutrients 2016; 8:nu8060336. [PMID: 27271657 PMCID: PMC4924177 DOI: 10.3390/nu8060336] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2016] [Revised: 05/23/2016] [Accepted: 05/30/2016] [Indexed: 12/22/2022] Open
Abstract
We investigated whether high-protein enteral nutrition with immune-modulating nutrients (IMHP) enriched with β-glucan stimulates immune function in critically ill patients. In a randomized double-blind placebo-controlled study, 30 patients consumed one of three types of enteral nutrition: a control or IMHP with and without β-glucan. The IMHP with β-glucan group showed increases in natural killer (NK) cell activities relative to the baseline, and greater increases were observed in NK cell activities relative to the control group after adjusting for age and gender. The IMHP groups with and without β-glucan had greater increases in serum prealbumin and decreases in high-sensitivity C-reactive protein (hs-CRP) than the control group. The control group had a greater decrease in peripheral blood mononuclear cell (PBMC) interleukin (IL)-12 production than the IMHP with and without β-glucan groups. In all patients, the change (Δ) in hs-CRP was correlated with Δ prealbumin and Δ PBMC IL-12, which were correlated with ΔNK cell activity and Δ prealbumin. This study showed beneficial effects of a combination treatment of β-glucan and IMHP on NK cell activity. Additionally, strong correlations among changes in NK cell activity, PBMC IL-12, and hs-CRP suggested that β-glucan could be an attractive candidate for stimulating protective immunity without enhanced inflammation (ClinicalTrials.gov: NCT02569203).

Abstract
It is well-known that bacteria can produce compounds which show anticancer effects. In present time, it is impossible to check all bacterial species on their possible production of anticancer compounds (AC) under different conditions. Thus, it is necessary to limit the area for search of bacterial products for the anticancer therapy. We propose that production of AC by bacteria is a part of microbial biological strategy under natural conditions. We propose that bacteria in soils, in water and on plants do not meet human tumors and their AC serve for the competition with eukaryotic organisms. Most probably, an epiphytic growth of bacilli is accompanied with production of compounds inhibiting eukaryotes. According to awaited profit for the AC-producing bacteria, the epiphytic groups of bacilli show inhibition of mycelial fungi which are a natural model of eukaryotic cells. An example of strain isolation and a primary test is presented.

Abstract
The crude polysaccharides were extracted from the fruiting bodies of Calocybe indica (CIP). The antioxidant activities of CIP were evaluated both in vitro and in vivo. Chemical characteristics of the polysaccharides were investigated. In in vitro antioxidant assay, CIP showed noticeable 2,2-diphenyl-1-picryl-hydrazyl (DPPH), hydroxyl radical scavenging activities, reducing power and lipid peroxidation inhibition. Chemical analysis showed the presence of carbohydrate, protein and the FTIR spectra revealed the presence of general characteristic absorption peak of the polysaccharides. For in vivo antioxidant activity, two different doses of CIP were orally administrated over a period of 6 weeks in a d-galactose (d-gal) induced aged mice model. Significantly lowered activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), levels of glutathione (GSH) and elevated malondialdehyde (MDA) levels were observed in brain and serum of d-galactose induced rats, when compared to control rats. Administration of CIP significantly raised the activities of SOD, CAT, GPx, levels of GSH and lowered the levels of MDA in mice brain and serum in a dose-dependent manner. The results suggested that CIP had potent antioxidant activity and could minimize the occurrence of age-associated disorders associated with involvement of free radicals.

Abstract
OBJECTIVE To evaluate the evidence from randomised trials for the efficacy and safety of phytotherapeutic interventions in the management of biochemically recurrent (BCR) prostate cancer, indicated by prostate-specific antigen (PSA) progression, numbers progressing to/time to initiation of androgen-deprivation therapy or salvage therapy. PATIENTS AND METHODS MEDLINE (Ovid), EMBASE (Ovid), AMED (Ovid), CINAHL (EBSCO) and the Cochrane Library databases were searched. Clinical trials investigating phytotherapeutic interventions as dietary supplements or dietary components, including multi-component herbal formulations, in men with BCR prostate cancer were located. Eight of nine authors contacted for further information responded. Methodological quality was assessed using the Cochrane Collaboration's risk of bias assessment tool. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement for reporting systematic reviews was followed. RESULTS Of 23 full-text articles assessed for eligibility, five met the criteria for inclusion. Two studies were placebo controlled; two were active control trials; and one a high-/low-dose trial. The interventions were administered as isolated phytochemicals (sulphoraphane), phytotherapeutic extracts [Pomi-T (pomegranate, turmeric, green tea and broccoli sprout extract), soy, lycopene, and POMx (pomegranate extract)], or plant-derived dietary items (soy and lycopene). All studies found serum PSA levels to stabilise, decrease or rise more slowly in a significant number of men, and three studies reported stabilising or lengthening of PSA-doubling time. Studies were generally of good quality, but sample sizes were predominantly small, and durations short. CONCLUSIONS High-quality studies in this area are lacking. Sulphoraphane, lycopene, soy isoflavones, POMx, and Pomi-T are safe and well tolerated. There is limited evidence that they can affect PSA dynamics. No recommendation can be made for the use of these agents in managing prostate cancer morbidity and mortality until high-quality, fully powered studies are available. Recommendations are made for improving reproducibility and translation of findings with regard to study population, study endpoints, design, and the reporting of phytotherapeutic interventions.

Abstract
It is widely acknowledged that the excessive reactive oxygen species (ROS) or reactive nitrogen species (RNS) induced oxidative stress will cause significant damage to cell structure and biomolecular function, directly or indirectly leading to a number of diseases. The overproduction of ROS/RNS will be balanced by nonenzymatic antioxidants and antioxidant enzymes. Polysaccharide or glycoconjugates derived from natural products are of considerable interest from the viewpoint of potent in vivo and in vitro antioxidant activities recently. Particularly, with regard to the in vitro antioxidant systems, polysaccharides are considered as effective free radical scavenger, reducing agent, and ferrous chelator in most of the reports. However, the underlying mechanisms of these antioxidant actions have not been illustrated systematically and sometimes controversial results appeared among various literatures. To address this issue, we summarized the latest discoveries and advancements in the study of antioxidative polysaccharides and gave a detailed description of the possible mechanisms.

Abstract
A fructan (ACPS-1) with a molecular weight of 11.2 kDa was isolated from Atractylodes chinensis rhizome and characterized by chemical derivatization, HPLC, GC-MS, FT-IR, and NMR. Structural analyses revealed that ACPS-1 is predominately composed of fructose and a small amount of glucose and a polymerization degree of about 53. The fructan was deduced to be an inulin-type fructan containing a linear backbone composed of (2→1)-linked β-d-Fruf residues. The in vitro antitumor activity of ACPS-1 was evaluated on four human cancer cell lines, including a cervical cancer cell line (Hela), two liver hepatocellular carcinoma cell lines (HepG2 and 7721), and an ovarian carcinoma cell line (Skov3). Results showed that ACPS-1 could significantly inhibit Hela, HepG2, and 7721 cell proliferation, especially HepG2, for which the fructan showed a proliferative inhibition rate as high as 87.40%. This result suggests that ACPS-1 may have anticancer potentiality against hepatocellular carcinoma and warrants further investigation.

Abstract
In the report, three bioactive fractions from Cerrena unicolor: laccase (LAC), endopolysaccharides (c-EPL), and low molecular weight (ex-LMS) were tested for the first time towards their antiviral, immunostimulatory, cytotoxic and antiproliferative effect. The immunomodulatory activity was studied by means of THP-1-derived macrophages able to synthesize and secrete IL-6 and TNF-α. We used cervical carcinoma cell lines SiHa (ATCC, HTB-35) and CaSki (ATCC, CRL 1550) to determine antitumor activity and human skin fibroblasts (HSF) as a control. SiHa and L929 cell lines were used in the antiviral activity assay to propagate HHV-1 and EMCV, respectively. LAC was the most active against HSV at an early stage of viral replication, whereas the activity of laccase against EMCV was evident after incubation of the virus with LAC before and after the adsorption step. Moreover, the investigations showed that the fungal c-EPL fraction stimulated the production and secretion of TNF-α and IL-6 by THP-1-derived macrophages up to a level of 2000 pg/ml and 400 pg/ml, respectively. It was indicated for the first time that the LAC and ex-LMS fractions exhibited anticancer activity. This resulted from their cytotoxic or antiproliferative action against the investigated tumor cells at concentrations above 250 μg/ml and 10 μg/ml, respectively.

Abstract
BACKGROUND Mushrooms are widely cited for their medicinal qualities, yet very few human intervention studies have been done using contemporary guidelines. OBJECTIVE The aim of this study was to determine whether consumption of whole, dried Lentinula edodes (shiitake) mushrooms could improve human immune function. Primary objectives were to ascertain whether L. edodes consumption would improve γδ-T cell proliferation and activation responses, quantify a dose response, and elicit cytokine secretion patterns. Secondary objectives included determining changes in natural killer T (NK-T) cell proliferation and activation, secretory immunoglobulin A (sIgA) in saliva, and C-reactive protein (CRP) in serum. DESIGN Fifty-two healthy males and females, aged 21-41 years, participated in a 4-week parallel group study, consuming either 5 or 10 g of mushrooms daily. Each subject had blood drawn before and after 4 weeks of daily L. edodes consumption. Saliva and serum were also collected. Peripheral blood mononuclear cells were cultured in autologous serum for 24 hours or 6 days, stained, and examined by flow cytometry. RESULTS Eating L. edodes for 4 weeks resulted in increased ex vivo proliferation of γδ-T (60% more, p < 0.0001) and NK-T (2-fold more, p < 0.0001) cells. Both cell types also demonstrated a greater ability to express activation receptors, suggesting that consuming mushrooms improved cell effector function. The increase in sIgA implied improved gut immunity. The reduction in CRP suggested lower inflammation. The pattern of cytokines secreted before and after mushroom consumption was significantly different; consumption resulted in increased interleukin (IL)-4, IL-10, tumor necrosis factor (TNF)-α, and IL-1α levels, a decreased macrophage inflammatory protein-1α/chemokine C-C ligand 3 (MIP-1α/CCL3) level, and no change to IL-6, IL-1β, MIP-1β, IL-17 and interferon (IFN)-γ levels. CONCLUSIONS Regular L. edodes consumption resulted in improved immunity, as seen by improved cell proliferation and activation and increased sIgA production. The changes observed in cytokine and serum CRP levels suggest that these improvements occurred under conditions that were less inflammatory than those that existed before consumption.

Abstract
Paclitaxel is generally used to treat cancers in clinic as an inhibitor of cell division. However, the acquired resistance in tumours limits its clinical efficacy. Therefore, the aim of this study was to detect whether co-treatment with lentinan enhanced the anti-cancer effects of paclitaxel in A549 cells. We found that the combination of paclitaxel and lentinan resulted in a significantly stronger inhibition on A549 cell proliferation than paclitaxel treatment alone. Co-treatment with paclitaxel and lentinan enhanced cell apoptosis rate by inducing caspase-3 activation. Furthermore, co-treatment with paclitaxel and lentinan significantly triggered reactive oxygen species (ROS) production, and increased thioredoxin-interacting protein (TXNIP) expression. Moreover, co-treatment with paclitaxel and lentinan enhanced TXNIP-NLRP3 interaction, and activated NLRP3 inflammasome whereat interleukin-1β levels were increased and cell apoptosis was induced. In addition, combination of paclitaxel and lentinan could activate apoptosis signal regulating kinase-1 (ASK1)/p38 mitogen-activated protein kinase (MAPK) signal which also contributed to cell apoptosis. Taken together, co-treatment with paclitaxel and lentinan exerts synergistic apoptotic effects in A549 cells through inducing ROS production, and activating NLRP3 inflammasome and ASK1/p38 MAPK signal pathway.

Abstract
Cancer immune evasion is a major stumbling block in designing effective anticancer therapeutic strategies. Although considerable progress has been made in understanding how cancers evade destructive immunity, measures to counteract tumor escape have not kept pace. There are a number of factors that contribute to tumor persistence despite having a normal host immune system. Immune editing is one of the key aspects why tumors evade surveillance causing the tumors to lie dormant in patients for years through "equilibrium" and "senescence" before re-emerging. In addition, tumors exploit several immunological processes such as targeting the regulatory T cell function or their secretions, antigen presentation, modifying the production of immune suppressive mediators, tolerance and immune deviation. Besides these, tumor heterogeneity and metastasis also play a critical role in tumor growth. A number of potential targets like promoting Th1, NK cell, γδ T cell responses, inhibiting Treg functionality, induction of IL-12, use of drugs including phytochemicals have been designed to counter tumor progression with much success. Some natural agents and phytochemicals merit further study. For example, use of certain key polysaccharide components from mushrooms and plants have shown to possess therapeutic impact on tumor-imposed genetic instability, anti-growth signaling, replicative immortality, dysregulated metabolism etc. In this review, we will discuss the advances made toward understanding the basis of cancer immune evasion and summarize the efficacy of various therapeutic measures and targets that have been developed or are being investigated to enhance tumor rejection.
