Abstract
Vikil 20 is an herbal formula produced in Ghana and is widely marketed as a product to boost immunity as well as for general well-being. However, the pharmacological effect of this herbal preparation has not been proven scientifically. Therefore, this study was aimed at investigating the antioxidative as well as the anti-prostate cancer effects of the product. To assess the antioxidative effect of Vikil 20, the DPPH and ABTS activities were investigated. The total phenolic content was investigated using the Folin-Ciocalteu method. The cytotoxic effect of Vikil 20 against prostate cancer (PC-3) cells as well as normal (RAW 264.7) cells was investigated using the MTT assay whereas its anti-metastatic effect was analyzed using the cell migration assay. The effect of Vikil 20 on cell adhesion was analyzed via the cell adhesion assay whereas its effect on TNF-α secretion was investigated using a TNF-α detection kit. Vikil 20 demonstrated significant antioxidant effects by suppressing 57.61% and 92.88% respectively of DPPH and ABTS radicals at 1000 µg/mL with total phenolic contents of 140.45 mg GAE/g. Vikil 20 suppressed the proliferation of PC-3 cells by reducing the number of viable cells to 49.5% while sparing the RAW, 264.7 cells. Further, Vikil 20 significantly suppressed both cellular migration and adhesion of prostate cancer cells. Finally, suppression of cellular migration and adhesion is associated with a reduction in TNF-α secretion by PC-3 cells. Taken together, Vikil 20 was found to possess significant antioxidant and anti-prostate cancer effects in vitro.

Zhao J, He R, Zhong H, Liu S, Liu X, Hussain M, Sun P. A cold-water extracted polysaccharide-protein complex from Grifola frondosa exhibited anti-tumor activity via TLR4-NF-κB signaling activation and gut microbiota modification in H22 tumor-bearing mice. Int J Biol Macromol 2023; 239:124291. [PMID: 37028620 DOI: 10.1016/j.ijbiomac.2023.124291] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2022] [Revised: 02/14/2023] [Accepted: 03/29/2023] [Indexed: 04/09/2023]
Abstract
Grifola frondosa polysaccharide-protein complex (G. frondosa PPC) is a polymer which consists of polysaccharides and proteins/peptides linked by covalent bonds. In our previous ex vivo research, it has been demonstrated that a cold-water extracted G. frondosa PPC has stronger antitumor activity than a G. frondosa PPC extracted from boiling water. The main purpose of the current study was to further evaluate the anti-hepatocellular carcinoma and gut microbiota regulation effects of two PPCs isolated from G. frondosa at 4 °C (GFG-4) and 100 °C (GFG-100) in vivo. The results exhibited that GFG-4 remarkably upregulated the expression of related proteins in TLR4-NF-κB and apoptosis pathway, thereby inhibiting the development of H22 tumors. Additionally, GFG-4 increased the abundance of norank_f__Muribaculaceae and Bacillus and reduced the abundance of Lactobacillus. Short chain fatty acids (SCFAs) analysis suggested that GFG-4 promoted SCFAs production, particularly butyric acid. Conclusively, the present experiments revealed GFG-4 has the potential of anti-hepatocellular carcinoma growth via activating TLR4-NF-κB pathway and regulating gut microbiota. Therefore, G. frondosa PPCs could be considered as safe and effective natural ingredient for treatment of hepatocellular carcinoma. The present study also provides a theoretical foundation for the regulation of gut microbiota by G. frondosa PPCs.

Current emerging trends in antitumor activities of polysaccharides extracted by microwave- and ultrasound-assisted methods. Int J Biol Macromol 2022; 202:494-507.

Abstract
This overview highlighted the in vitro and in vivo antitumor effects of polysaccharides extracted by ultrasound- and microwave-assisted solvent extraction methods. The polysaccharide fragments with stronger antiproliferation, antitumoral, and anticarcinoma effects can be identified through purification, fractionation, and bio-analytical assessments. Most of the extracted glucan-based polysaccharides in a dose-dependent manner inhibited the growth of human cancer cell types with cell death-associated morphological changes. Glucans, glucogalactans, and pectins without any cytotoxicity on normal cells showed the antitumor potential by the apoptosis induction and the inhibition of their tumorigenesis, metastasis, and transformation. There is a significantly high association among antiproliferative activities, structural features (e.g., molecular weight, monosaccharide compositions, and contents of sulfate, selenium, and uronic acid), and other bio-functionalities (e.g., antiradical and antioxidant) of isolated polysaccharides. The evaluation of structure-activity relationships of antitumor polysaccharides is an intriguing step forward to develop highly potent anticancer pharmaceuticals and foods without any side effects.

Abstract
There has been a significant research interest in nanocrystals as a promising technology for improving the therapeutic efficacy of poorly water-soluble drugs, such as resveratrol. Little is known about the interaction of nanocrystals with biological tissue. The aim of this study was to investigate the potential use of resveratrol (RSV) and its nanocrystals (NANO-RSV) as antitumor agents in Ehrlich ascites tumour (EAT)-bearing mice and the interaction of nanocrystals with biological tissue through biochemical and histological changes of kidney, liver and EAT cells. After intraperitoneal injection of 2.5 × 106 cells into the abdominal cavity of mice, treatment of animals was started next day by injecting RSV or NANO-RSV at a dose of either 25 or 50 mg/kg every other day for 14 days. The results show that the administration of resveratrol and its nanocrystals lead to significant reductions in the proliferation of tumour cells in the abdominal cavity, and a reduction of the number of blood vessels in the peritoneum, with low systemic toxicity. In histopathological examinations, greater hepatocellular necrosis and apoptosis, hepatic fibrosis around the central vein and degeneration with minor fatty change were observed with RSV than with NANO-RSV. Inflammation with proximal tubular necrosis and renal glomerulus swelling were also observed, together with slight elevation of several biochemical parameters in both the RSV and NANO-RSV groups. In order to increase the beneficial effects and reduce risks associated with resveratrol nanocrystals, additional factors such as dose, genetic factors, health status, and the nature of the target cells should also be considered.

Abstract
A novel Angelica dahurica polysaccharide (ADP) with Mw of 6.09 × 103 Da was isolated. The contents of total sugar and uronic acid in ADP were 91.04% and 12.69%. The structure characteristics indicated that ADP was an acidic polysaccharide consisting of rhamnose, arabinose, galactose, glucose, mannose, glucuronic acid and galacturonic acid (0.09: 0.61: 1.88: 1: 0.14: 0.63: 0.03). Moreover, there were →3)-Manp-(1→, →4, 6)-Galp-(1→, →4)-Galp-(1→, →3)-Glcp-(1→, →5)-Araf-(1→, →2)-Galp-(1→ in ADP with relative molar ratios of 0.32:0.57:0.29:0.95:0.71:0.26. In vivo experiments suggested that ADP significantly inhibited the tumor growth of mice, increased the activities of spleen lymphocytes and natural killer (NK) cells, improved the cytokine level (IL-2 and TNF-α) and the proportions of lymphocyte subsets in the peripheral blood. The tumor cell progression was arrested in the G1 phase, and the apoptosis rate of tumor cells were 7.54% and 19.32% at the dose of 100 and 200 mg/kg, which was consistent with the results of pathological observation. In summary, the study might provide a theoretical basis for the application on functional foods containing Angelica dahurica polysaccharides.

Abstract
Cancer is one of the several comorbidities that have been linked with chronic cutaneous inflammatory diseases namely psoriasis/psoriatic arthritis and hidradenitis suppurativa. Although the chronic inflammatory state, typical of the diseases, may induce pro-tumorigenic effects, the debate whether or not the drugs currently used in clinical practice do in facts increase a patient's risk of malignancy remains largely unsolved. The therapeutic armamentarium has been greatly enhanced at least in the last two decades with the advent of biologics, a heterogeneous group of laboratory-engineered agents with more in the pipeline, and other targeted small molecules. Among the organ systems, skin results as one of the most commonly affected, non-melanoma skin cancers being the main drug-induced manifestations as side effect in course of these treatments. The objective of the study is to systematically review the cutaneous malignancy risk of the newer therapies through an overview of meta-analyses and observational studies on the topic.

Abstract
OBJECTIVES To estimate the prevalence and incidence of malignancy and its types in psoriatic arthritis (PsA) and psoriasis without arthritis (PsC) patients, in comparison to the general population, and to identify the predictive factors for developing cancer in psoriatic disease (PsD). METHODS PsA patients followed prospectively since 1978 and PsC patients followed since 2006 at 6-to-12 month intervals according to a standard protocol were included. Malignancies were recorded prospectively and linkages with Cancer Care Ontario and the Death Registry were carried out to confirm the presence and type of malignancy up to December 2016. Standardized incidence ratios (SIR) were calculated for overall cancers and by age and sex. Cox regression analysis was conducted to identify risk factors associated with the development of malignancy after the diagnosis of PsD. RESULTS 2051 patients (PsD) were included of whom 228 (11%) developed cancer. 168 patients developed cancer after first clinic visit and are included in this report. Overall SIR for malignancy was 0.83 (0.68, 1.00), SIR for females was 1.06 (0.80, 1.37), and for males was 0.67 (0.50, 0.88). The most common malignancies were skin, breast, and hematological. Skin cancer was the only specific cancer that had a higher incidence than the general population with SIR = 3.37 (1.84, 5.66). There was insufficient evidence to suggest an increased risk of malignancy associated with biologics use. CONCLUSIONS In this long-term prospective follow-up of patients with PsA and PsC the overall malignancy risk was not found to be higher than the general population, while skin cancer increased.

Abstract
Due to frequent drug resistance and/or unwanted side-effects during conventional and targeted cancer treatments, development of multi-target therapies is an important research field. Medicinal mushrooms’ isolated specific compounds and mushroom extracts have been already proven as non-toxic multi-target inhibitors of specific oncogenic pathways, as well as potent immunomodulators. However, research on antitumor effects of multiple-species extract mixtures was limited so far. The aim of this study was therefore, a study of medicinal mushroom preparations AGARIKON.1 and AGARIKON PLUS on colorectal cell lines in vitro and colorectal mice model in vivo. We found a significant antiproliferative and pro-apoptotic effect of tested medicinal mushroom preparations on colorectal (HCT-116, SW620) tumor cell lines, while the effect on human fibroblast cell line (WI-38) was proliferative emphasizing a specificity towards tumor cell lines. We further investigated the effect of the medicinal mushroom preparations AGARIKON.1 and AGARIKON PLUS in various combinations with conventional cytostatic drug 5-fluorouracil in the advanced metastatic colorectal cancer mouse model CT26.WT. AGARIKON.1 and AGARIKON PLUS exhibited immunostimulatory and antiangiogenic properties in vivo which resulted in significantly increased survival and reduction in tumor volume. The antitumor effects of AGARIKON.1 and AGARIKON PLUS, with or without 5-fluorouracil, are based on M1 macrophage polarization enhancement, inhibition of M2 and tumor-associated macrophage (TAM) polarization, effects on T helper cell Th1/Th2/Th17 cytokine profiles, direct inhibition of CT26.WT tumor growth, inhibition of vascular endothelial growth factors (VEGF) and metalloproteinases 2 and 9 (MMP-2 and MMP-9) modulation. The administration of AGARIKON.1 and AGARIKON PLUS did not show genotoxic effect. This data provides good basis for an expanded translational study.

Abstract
Innate lymphoid cells (ILCs) are important for both tissue immunity and tissue homeostasis. They are classified into three groups: Group 1 ILCs include NK cells, which are important in eliciting immunity against intracellular pathogens; group 2 ILCs protect against parasitic helminths; and group 3 ILCs protect against extracellular pathogens. The role of ILCs in cancer immunity remains unclear. In this chapter, we discuss methods for isolating and characterizing tumor-infiltrating ILC subsets within the tumor microenvironment in an experimental murine model of B16 melanoma. The chapter also highlights the expression of PD-1 on the various ILC subsets within the tumor microenvironment.

Abstract
Neurocutaneous melanosis (NCM) is the condition of abnormal melanocyte deposition in the leptomeninges and brain parenchyma. Associated with congenital melanocytic nevi, NCM can result in neurologic deficits, hydrocephalus, and rarely, malignant transformation of cells. We present the case of a 16-year-old boy with NCM who developed malignant leptomeningeal melanoma following immunosuppression with a TNFα inhibitor. To our knowledge, this is the first reported case of a patient with known NCM undergoing malignant transformation after anti-TNF therapy for inflammatory bowel disease.

Abstract
Novel polymer-drug conjugates (CNC) were prepared from carboxymethyl chitosan (CMCS) and norcantharidin (NCTD) via amidation reaction and characterized by FTIR and 1H NMR spectroscopy. The aim of this study was to elucidate the antitumor efficacy of CNC on gastric cancer and the possible underlying mechanisms. The CNC conjugates possessed significant inhibitory effects on the proliferation of SGC-7901 cells and suppressed the migration as well as tube formation of HUVECs. Besides, Hoechst 33258 staining and Annexin V-FITC/PI detection suggested that the conjugates were more effective in triggering apoptosis of SGC-7901 cells compared with free NCTD. Moreover, CNC remarkably reduced systemic toxicity and enhanced the antitumor efficacy in vivo with a tumor suppression rate of 59.57% against SGC-7901 gastric tumor in BALB/c nude mice. Further investigation about the underlying mechanisms indicated that CNC could upregulate expressions of TNF-α and Bax, and downregulate expressions of VEGF, Bcl-2, MMP-2 and MMP-9, thereby inhibiting tumor metastasis and inducing apoptosis in vivo. Overall, our results demonstrated that CNC might be a promising and feasible polymer therapeutics for gastrointestinal tumor therapy.

Anti-breast Cancer Activity of SPG-56 from Sweet Potato in MCF-7 Bearing Mice in Situ through Promoting Apoptosis and Inhibiting Metastasis. Sci Rep 2019; 9:146. [PMID: 30651572 PMCID: PMC6335419 DOI: 10.1038/s41598-018-29099-x] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2017] [Accepted: 07/01/2018] [Indexed: 01/19/2023] Open
Abstract
SPG-56 is a newly isolated glycoprotein from sweet potatoes (Zhongshu NO. 1), but its value for suppressing breast cancer progression remains unknown. This study was designed to investigate the potential anti-cancer effects of SPG-56, which consists of 2.9% sugar and 97.1% protein. The effects of SPG-56 on the proliferation and apoptosis of breast cancer cells were determined using CCK-8 and Hoechst 33342 assays and flow cytometry, after staining with Annexin V and PI respectively. The activities of SPG-56 against breast cancer were examined using female BALB/c nude mice orthotopically implanted with human breast carcinoma cells of the types MCF-7 and 4T1-Luc. The cellular experiments showed that SPG-56 inhibited proliferation and promoted apoptosis of MCF-7 cells dose- and time-dependently. Oral administration of SPG-56 significantly suppressed the development of MCF-7 tumor cells (P < 0.01) as compared with an untreated group. The serum tumor markers CEA, CA125 and CA153 in a 240 mg/kg/d SPG-56 decreased by 54.8%, 91.8%, and 90.3%, respectively. The experiments further demonstrated that SPG-56 inhibited the metastasis of breast cancer in MCF-7 and 4T1-bearing mice by altering the expression of MMP2, MMP9, VEGF, Occludin and Claudin. It is concluded that SPG-56 may have potential as a novel anti-tumor candidate for breast cancer.

Abstract
BACKGROUND Moderate to severe psoriasis often requires treatment with systemic agents, many of which have immunosuppressive properties and could increase cancer risk, including nonmelanoma skin cancer (NMSC). OBJECTIVE We sought to estimate the overall malignancy rate (excluding NMSC) and NMSC rate among 5889 patients with systemically treated psoriasis. METHODS We identified a cohort of adult Kaiser Permanente Northern California health plan members with psoriasis diagnosed from 1998 to 2011 and treated with at least 1 systemic antipsoriatic agent and categorized them into ever-biologic or nonbiologic users. Malignancy rates were calculated per 1000 person-years of follow-up with 95% confidence intervals (CI). Crude and confounder-adjusted hazard ratios (aHRs) were calculated using Cox regression. RESULTS Most biologic-exposed members were treated with TNF-alfa inhibitors (n = 2214, 97%). Overall incident cancer rates were comparable between ever-biologic as compared to nonbiologic users (aHR 0.86, 95% CI 0.66-1.13). NMSC rates were 42% higher among individuals ever exposed to a biologic (aHR 1.42, 95% CI 1.12-1.80), largely driven by increased cutaneous squamous cell carcinoma risk (aHR 1.81, 95% CI 1.23-2.67). LIMITATIONS No information was available on disease severity. CONCLUSION We found increased incidence of cutaneous squamous cell carcinoma among patients with systemically treated psoriasis who were ever exposed to biologics, the majority of which were TNF-alfa inhibitors. Increased skin cancer surveillance in this population may be warranted.

Abstract
Innate lymphoid cells (ILCs) are a group of immune cells of the lymphoid lineage that do not possess antigen specificity. The group includes natural killer (NK) cells, lymphoid tissue inducer (LTi) cells and the recently identified ILC1s, ILC2s and ILC3s. Although the role of NK cells in the context of cancer has been well established, the involvement of other ILC subsets in cancer progression and resistance is just emerging. Here, we review the literature on the role of the different ILC subsets in tumor immunity and discuss its implications for cancer treatment and monitoring.

Abstract
Introduction The association between cancer and use of biologic therapy among rheumatoid arthritis (RA) patients remains controversial. We aimed to compare the relative risk of cancer development between RA patients taking tumor necrosis factor α (TNFα) antagonists and those taking nonbiologic disease-modifying anti-rheumatic drugs (nbDMARDs). Methods We conducted a nationwide cohort study between 1997 and 2011 using the Taiwan National Health Insurance Research Database. The risk of newly diagnosed cancer was compared between patients starting TNF-α antagonists (biologics cohort) and matched subjects taking nbDMARDs only (nbDMARDs cohort). Cumulative incidences and hazard ratios (HR) were calculated after adjusting for competing mortality. Standardized incidence ratio (SIR) was calculated for cancer risk. Multivariate analyses were performed using Cox proportional hazards model. Results We compared 4426 new users of TNF-α antagonists and 17704 users of nbDMARDs with similar baseline covariate characteristics. The incidence rates of cancer among biologics and nbDMARDs cohorts were 5.35 (95% confidence interval (CI) 4.23 to 6.46) and 7.41 (95% CI 6.75 to 8.07) per 1000 person-years, respectively. On modified Cox proportional hazards analysis, the risk of cancer was significantly reduced in subjects in biologics cohort (adjusted HR 0.63, 95% CI 0.49 to 0.80, P < .001), after adjusting for age, gender, disease duration, major co-morbidities, and prior use of DMARDs and corticosteroids. However, there was an increased risk for hematologic cancers in biologics cohort, yet without statistical significance. The effect of biologics was consistent across all multivariate stratified analyses and the association between biologics use and cancer risk was independent of dosage of concomitant nbDMARDs. Conclusion These findings suggested that RA patients taking TNF-α antagonist are associated with a lower risk of cancer, but not for hematologic cancers, than RA patients taking nbDMARDs alone.

Abstract
OBJECTIVES To develop and/or update fact sheets about TNFα antagonists treatments, in order to assist physicians in the management of patients with inflammatory joint disease. METHODS 1. selection by a committee of rheumatology experts of the main topics of interest for which fact sheets were desirable; 2. identification and review of publications relevant to each topic; 3. development and/or update of fact sheets based on three levels of evidence: evidence-based medicine, official recommendations, and expert opinion. The experts were rheumatologists and invited specialists in other fields, and they had extensive experience with the management of chronic inflammatory diseases, such as rheumatoid. They were members of the CRI (Club Rhumatismes et Inflammation), a section of the Société Francaise de Rhumatologie. Each fact sheet was revised by several experts and the overall process was coordinated by three experts. RESULTS Several topics of major interest were selected: contraindications of TNFα antagonists treatments, the management of adverse effects and concomitant diseases that may develop during these therapies, and the management of everyday situations such as pregnancy, surgery, and immunizations. After a review of the literature and discussions among experts, a consensus was developed about the content of the fact sheets presented here. These fact sheets focus on several points: 1. in RA and SpA, initiation and monitoring of TNFα antagonists treatments, management of patients with specific past histories, and specific clinical situations such as pregnancy; 2. diseases other than RA, such as juvenile idiopathic arthritis; 3. models of letters for informing the rheumatologist and general practitioner; 4. and patient information. CONCLUSION These TNFα antagonists treatments fact sheets built on evidence-based medicine and expert opinion will serve as a practical tool for assisting physicians who manage patients on these therapies. They will be available continuously at www.cri-net.com and updated at appropriate intervals.

Abstract
The stroma of hepatocellular carcinoma (HCC) is markedly infiltrated with activated hepatic stellate cells (HSCs), and associated invasion and metastasis of HCC. However, little is known of the role of HSCs in immune responses in HCC. The Buffalo rat HCC model was established. Quiescent HSCs (qHSCs) and intratumoral HSCs (tHSCs) were isolated. Surface molecules of tHSC were detected by flow cytometry, and gene expression was analyzed by fluorescence quantitative RT-PCR. T cell proliferation was monitored by [(3)H]-thymidine ((3)H-TdR) incorporation into DNA, and cytotoxic activity was assessed by measuring the release of (51)Cr. The level of cytokine expression by T cells was measured by enzyme-linked immunosorbent assay. T cell apoptosis was detected by double-stained terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) and anti-CD3 antibodies. The migration and invasion of HCC was observed by transwell experiments. tHSCs express low levels of major histocompatibility complex (MHC) class I, MHC class II, and costimulatory molecules, and produce varying levels of cytokines. Addition of the tHSCs suppressed thymidine uptake by T cells that were stimulated by alloantigens or by anti-CD3-mediated T-cell receptor ligation. The tHSC-induced T-cell hyporesponsiveness was associated with enhanced T-cell apoptosis, and contributed to the migration and invasion of hepatoma cell. tHSCs was associated with markedly enhanced expression of B7-H1. Blockade of B7-H1/PD-1 ligation significantly reduced HSC immunomodulatory activity, and hepatoma cell migration and invasion. tHSCs can induce T cell apoptosis, suggesting an important role for B7-H1. The interactions between tHSCs and T cells may contribute to hepatic immune tolerance and invasion and migration of HCC.

Abstract
Tumorigenesis is in many respects a process of dysregulated cellular evolution that drives malignant cells to acquire six phenotypic hallmarks of cancer, including their ability to proliferate and replicate autonomously, to resist cytostatic and apoptotic signals, and to induce tissue invasion, metastasis, and angiogenesis. Transforming growth factor-β (TGF-β) is a potent pleiotropic cytokine that functions as a formidable barrier to the development of cancer hallmarks in normal cells and tissues. Paradoxically, tumorigenesis counteracts the tumor suppressing activities of TGF-β, thus enabling TGF-β to stimulate cancer invasion and metastasis. Fundamental gaps exist in our knowledge of how malignant cells overcome the cytostatic actions of TGF-β, and of how TGF-β stimulates the acquisition of cancer hallmarks by developing and progressing human cancers. Here we review the molecular and cellular mechanisms that underlie the ability of TGF-β to mediate tumor suppression in normal cells, and conversely, to facilitate cancer progression and disease dissemination in malignant cells.

Abstract
OBJECTIVE Malignancies reported in children using tumor necrosis factor alpha (TNFalpha) blockers have raised concerns of a potential increased risk. This study was undertaken to investigate postmarketing reports of malignancy in children treated with TNF blockers. METHODS The FDA's Adverse Event Reporting System was searched to identify malignancies associated with the use of infliximab, etanercept, and adalimumab in children in whom therapy was initiated between the ages of 0 and 18 years. The reporting rates for infliximab and etanercept were compared with the background rate of malignancy in the general pediatric population. RESULTS Forty-eight reports of malignancy in children were identified: 31 following infliximab use, 15 following etanercept use, and 2 following adalimumab use. Half of the malignancies reported were lymphomas and included both Hodgkin's and non-Hodgkin's lymphoma. The remaining reported cases involved a variety of different malignancies including leukemia, melanoma, and solid organ cancers. The majority of the reported cases (88%) involved the concomitant use of other immunosuppressants. Reporting rates for malignancy showed that infliximab had a consistently higher reporting rate when compared with background rates in the general pediatric population for lymphomas and all malignancies. The reporting rates for etanercept were elevated above background for lymphomas and were on par with background for all malignancies. CONCLUSION There is evidence that treatment with TNF blockers in children may increase the risk of malignancy. However, the cases were confounded by the potential risk of malignancy associated with underlying illnesses and the use of concomitant immunosuppressants; therefore, a clear causal relationship could not be established.

Abstract
The tumor necrosis factor (TNF) receptor super family comprises of members that induce two distinct signaling cascades, leading to either cell survival or apoptosis. However, in prostate cancer (PCa), TNF-mediated prosurvival signaling is the predominant pathway that leads to cell survival and resistance to therapy. Although inhibition of TNF signaling by pharmacological agents or monoclonal antibodies has gained importance in the field of cancer therapy, toxicity to normal cells has impaired their extensive use for cancer treatment. We previously identified a natural, nontoxic compound psoralidin that inhibited viability and induced apoptosis in androgen independent prostate cancer (AIPC) cells. Thus, the goal of our study is to investigate whether psoralidin inhibits TNF-mediated prosurvival signaling in AIPC cells. Our results suggest that psoralidin inhibits constitutive and TNF-induced expression of TNF-alpha and its downstream prosurvival signaling molecules such as NF-kappaB and Bcl-2 in AIPC cells. On the other hand, psoralidin simultaneously induces the death receptor (DR)-mediated apoptotic signaling eventually causing the activation of caspase cascade and resultant induction of apoptosis. Oral administration of psoralidin inhibits expression of TNF-alpha and NF-kappaB/p65 in tumor sections, resulting in tumor regression in PC-3 xenografts. Our results suggest that psoralidin inhibits TNF-mediated survival signaling in AIPC and thus is a potent therapeutic agent for prostate cancer.

Abstract
OBJECTIVE The objective was to compare cancer risk in a RA cohort population treated with TNF antagonists, and identify the characteristics of the patients at higher risk. METHODS The study involved 1114 RA patients treated with anti-TNF agents after failing to respond to traditional DMARDs, 1064 of whom were evaluable for adverse events over an average observational period of 23.32 months. The relative cancer risks (expressed as hazard ratios) in the anti-TNF treated patients were estimated using univariate and multivariate analyses. The rate of cancer in this cohort was compared with that in the general population using data from the Varese and Milan Cancer Report. RESULTS There were 18 incident cases (1.7%), 4 of which involved lymphomas. Comparison with the general population showed that the overall cancer risk was similar, but the risk of lymphoma was about five times higher in the RA patients treated with a biological agent. Higher RR were found in males (HR 4.95, 95% CI 1.97-12.48; p=0.001) and patients aged >65 years (HR 2.72, 95% CI 1.08-6.84; p=0.034); combined therapy with methotrexate seemed to be protective (HR 0.31, 95% CI 0.11-0.87; p=0.026). CONCLUSION The overall cancer risk in RA patients treated with anti-TNF seemed to be similar to that in the general population in the same geographical area, but the risk of haematological cancer was significantly greater. The demographic and clinical factors associated with a higher risk of cancer in our cohort were male gender and an age of >65 years.

Abstract
TGF-beta plays an essential role in maintaining tissue homeostasis through its ability to induce cell cycle arrest, differentiation and apoptosis, and to preserve genomic stability. Thus, TGF-beta is a potent anticancer agent that prohibits the uncontrolled proliferation of epithelial, endothelial and hematopoietic cells. Interestingly, tumorigenesis typically elicits aberrations in the TGF-beta signaling pathway that engenders resistance to the cytostatic activities of TGF-beta, thereby enhancing the development and progression of human malignancies. Moreover, these genetic and epigenetic events conspire to convert TGF-beta from a suppressor of tumor formation to a promoter of their growth, invasion and metastasis. The dichotomous nature of TGF-beta during tumorigenesis is known as the 'TGF-beta paradox', which remains the most critical and mysterious question concerning the physiopathological role of this multifunctional cytokine. Here we review recent findings that directly impact our understanding of the TGF-beta paradox and discuss their importance to targeting the oncogenic activities of TGF-beta in developing and progressing neoplasms.

Abstract
BACKGROUND There are multiple therapeutic options for the treatment of moderate to severe psoriasis. The process of choosing among potential treatment options requires both the physician and the patient to weigh the benefits of individual modalities against their potential risks. Traditional systemic therapies for psoriasis, including methotrexate (MTX) and cyclosporine (CsA), have a well-documented array of toxicities, particularly end-organ toxicities. Over the past several years, the use of biologic therapies for the treatment of moderate to severe psoriasis has been a major clinical and research focus. With the advent of these novel immunosuppressive therapies, one of the central safety issues surrounding these agents is their potential to increase the risk of malignancy. OBJECTIVE Our objective was to review the risk of malignancy associated with therapies for moderate to severe psoriasis, including phototherapy, traditional systemic therapies, and biologic therapies. We reviewed the existing body of literature in order to define the known incidence of malignancy associated with psoralen and ultraviolet A (PUVA), narrowband and broadband ultraviolet B (UVB), MTX, CsA, mycophenolate mofetil (MMF), and biologic therapies, including alefacept, efalizumab, infliximab, etanercept, adalimumab, and ustekinumab. RESULTS PUVA, when given long term, is associated with increased risks of cutaneous squamous cell carcinoma and malignant melanoma. Reviews of studies on UVB, both narrowband and broadband, do not indicate any increased risk of nonmelanoma skin cancer or melanoma. The traditional systemic psoriasis therapies-MTX, CsA, and MMF-may be associated with an increased risk of lymphoproliferative disorders during treatment, demonstrated in clinical trials in patients with rheumatoid arthritis and documented in case reports concerning psoriasis patients. The risk of malignancy with biologic therapy is still unclear. However, the majority of studies examining this carcinogenic risk suggest that tumor necrosis factor-alpha inhibitors may cause a slightly increased risk of cancer, including nonmelanoma skin cancer and hematologic malignancies. LIMITATIONS The majority of studies cited in this review lack the power and randomization of large clinical trials, as well as the long-term follow-up periods which would further substantiate the hypothetical link between these antipsoriatic treatment regimens and the potential for malignancy. Because of the substantial lack of clinical data, the majority of studies evaluated focus on the treatment of patients with rheumatoid arthritis, which is a systemic inflammatory disorder comparable to psoriasis. Additionally, the increased risk of malignancy associated with psoriasis itself is a confounding factor. CONCLUSION Many of the therapies for moderate to severe psoriasis, including PUVA, traditional systemic therapies, and some biologic therapies, may increase the risk of malignancy. Appropriate patient counseling and selection, as well as clinical follow-up, are necessary to maximize safety with these agents. Further long-term study is necessary to more precisely quantify the risks associated with biologic therapies.

Abstract
Tumor necrosis factor (TNF)-alpha is implicated in the same time in apoptosis and in cell proliferation. TNF-alpha not only acts as pro-inflammatory cytokine conducing to wide spectrum of human diseases including inflammatory diseases, but can also induce tumor development. The molecular mechanisms of TNF-alpha functions have been intensively investigated. In this review we covered TNF-alpha, the molecule, its signaling pathway, and its therapeutic functions. We provide a particular insight in its paradoxical role in tumor promotion and in its use as anti-tumor agent. This review considers also the recent findings regarding TNF-alpha inhibitors, their pharmacokinetics, and their pharmacodynamics. Six TNF-alpha inhibitors have been considered here: Infliximab, Adalimumab, Golimumab, CDP870, CDP571, Etanercept, and Thalidomide. We discussed the clinical relevance of their functions in treatment of several diseases such as advanced inflammatory rheumatic and bowel disease, with a focus in cancer treatment. Targeting TNF-alpha by these drugs has many side effects like malignancies development, and the long-term sequels are not very well explored. Their efficacy and their safety were discussed, underscoring the necessity of close patients monitoring and of their caution use.

Abstract
Tumor necrosis factor (TNF) is a multifunctional cytokine that plays important roles in diverse cellular events such as cell survival, proliferation, differentiation, and death. As a pro-inflammatory cytokine, TNF is secreted by inflammatory cells, which may be involved in inflammation-associated carcinogenesis. TNF exerts its biological functions through activating distinct signaling pathways such as nuclear factor-kappaB (NF-kappaB) and c-Jun N-terminal kinase (JNK). NF-kappaB is a major cell survival signal that is anti-apoptotic, whereas sustained JNK activation contributes to cell death. The crosstalk between the NF-kappaB and JNK is involved in determining cellular outcomes in response to TNF. In regard to cancer, TNF is a double-dealer. On one hand, TNF could be an endogenous tumor promoter, because TNF stimulates the growth, proliferation, invasion and metastasis, and tumor angiogenesis of cancer cells. On the other hand, TNF could be a cancer killer. The property of TNF in inducing cancer cell death renders it a potential cancer therapeutic, although much work is needed to reduce its toxicity for systematic TNF administration. Recent studies have focused on sensitizing cancer cells to TNF-induced apoptosis through inhibiting survival signals such as NF-kappaB, by combined therapy. In this article we provide an overview of the roles of TNF-induced signaling pathways in cancer biology with specific emphasis on carcinogenesis and cancer therapy.
