Liu MH, Liu F, Ng TB, Liu ZK. New fungal protein from Pleurotus ferulae lanzi induces AMPK-mediated autophagy and G1-phase cell cycle arrest in A549 lung cancer cells. Int J Biol Macromol 2023; 244:125453. [PMID: 37330099 DOI: 10.1016/j.ijbiomac.2023.125453] [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: 03/13/2023] [Revised: 06/11/2023] [Accepted: 06/14/2023] [Indexed: 06/19/2023]
Abstract
A new protein, designated PFAP, with activity against non-small cell lung cancer (NSCLC), was isolated from Pleurotus ferulae lanzi, a medicinal and edible mushroom. The purification method involved hydrophobic interaction chromatography on a HiTrap Octyl FF column and gel filtration on a Superdex 75 column. Sodium dodecyl-sulfate polyacrylamide gel electrophoresis (SDS-PAGE) revealed a single band with a molecular weight of 14.68 kDa. Following de novo sequencing and liquid chromatography-tandem mass spectrometry, PFAP was identified as a protein consisting of 135 amino acid residues, with a theoretical molecular weight of 14.81 kDa. Tandem mass tag (TMT)™-based quantitative proteomic analysis and western blotting revealed that AMP-activated protein kinase (AMPK) was significantly upregulated in NSCLC A549 cells, following PFAP treatment. The downstream regulatory factor mammalian target of rapamycin (mTOR) was suppressed, resulting in the activation of autophagy and upregulated expressions of P62, LC3 II/I, and other related proteins. PFAP blocked NSCLC A549 cells in the G1 phase of the cell cycle via upregulating P53 and P21, while subsequently downregulating the expression of cyclin-dependent kinases. PFAP suppresses tumour growth via the same mechanism in a xenograft mouse model in vivo. These results demonstrate that PFAP is a multifunctional protein with anti-NSCLC properties.

Unraveling the function of epithelial-mesenchymal transition (EMT) in colorectal cancer: Metastasis, therapy response, and revisiting molecular pathways. Biomed Pharmacother 2023; 160:114395. [PMID: 36804124 DOI: 10.1016/j.biopha.2023.114395] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2023] [Revised: 02/03/2023] [Accepted: 02/08/2023] [Indexed: 02/17/2023] Open
Abstract
Colorectal cancer (CRC) is a dangerous form of cancer that affects the gastrointestinal tract. It is a major global health concern, and the aggressive behavior of tumor cells makes it difficult to treat, leading to poor survival rates for patients. One major challenge in treating CRC is the metastasis, or spread, of the cancer, which is a major cause of death. In order to improve the prognosis for patients with CRC, it is necessary to focus on ways to inhibit the cancer's ability to invade and spread. Epithelial-mesenchymal transition (EMT) is a process that is linked to the spread of cancer cells, also known as metastasis. The process transforms epithelial cells into mesenchymal ones, increasing their mobility and ability to invade other tissues. This has been shown to be a key mechanism in the progression of colorectal cancer (CRC), a particularly aggressive form of gastrointestinal cancer. The activation of EMT leads to increases in the spread of CRC cells, and during this process, levels of the protein E-cadherin decrease while levels of N-cadherin and vimentin increase. EMT also contributes to the development of resistance to chemotherapy and radiation therapy in CRC. Non-coding RNAs, such as long non-coding RNAs (lncRNAs) and circular RNAs (circRNAs), play a role in regulating EMT in CRC, often through their ability to "sponge" microRNAs. Anti-cancer agents have been shown to suppress EMT and reduce the progression and spread of CRC cells. These findings suggest that targeting EMT or related mechanisms may be a promising approach for treating CRC patients in the clinic.

Euxanthone Suppresses the Proliferation, Migration and Invasion of Human Medulloblastoma Cells by Inhibiting the RANK/RANKL Pathway. Pharmacogn Mag 2023. [DOI: 10.1177/09731296221138649] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 03/19/2023] Open
Abstract
Background: Euxanthone is a plant-based flavonoid that is mostly isolated from a Chinese medicinal plant, Polygala caudate. This study was designed to evaluate the anticancer effects of euxanthone against human medulloblastoma cells. Materials and Methods: Cell viability was evaluated by CCK-8 and EdU assays. Apoptotic cell percentage was determined by annexin V/PI assay. The mRNA expression was determined by qRT-PCR. Wound healing and transwell assays were used to assess cell migration and invasion. Results: The results revealed aberrant activation of RANK/RANKL pathway in human medulloblastoma tissues and cell lines. Euxanthone suppressed the proliferation of the D425 medulloblastoma cells with comparatively lower cytotoxic effects against the normal human cerebellar granule cells. The IC50 of euxanthone against the D425 cells was found to be 10 µM. Interestingly, silencing of receptor activator of nuclear factor kβ (RANK) could also suppress the proliferation of the D425 cells via induction of apoptosis. Nonetheless, overexpression of RANK could abolish the cytotoxic effects of euxanthone on the D425 cells. Finally, wound-heal and transwell assay showed that euxanthone suppressed the migration and invasion of the D425 medulloblastoma cells. Conclusion: Collectively, the results revealed the anticancer effects of euxanthone against human medulloblastoma cells via RANK/RANKL pathway. These results suggest the potential of euxanthone as a lead molecule in the development of chemotherapy for medulloblastoma.

Phenolic Phytochemicals for Prevention and Treatment of Colorectal Cancer: A Critical Evaluation of In Vivo Studies. Cancers (Basel) 2023; 15:cancers15030993. [PMID: 36765950 PMCID: PMC9913554 DOI: 10.3390/cancers15030993] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2022] [Revised: 01/30/2023] [Accepted: 01/30/2023] [Indexed: 02/08/2023] Open
Abstract
Colorectal cancer (CRC) is the third most diagnosed and second leading cause of cancer-related death worldwide. Limitations with existing treatment regimens have demanded the search for better treatment options. Different phytochemicals with promising anti-CRC activities have been reported, with the molecular mechanism of actions still emerging. This review aims to summarize recent progress on the study of natural phenolic compounds in ameliorating CRC using in vivo models. This review followed the guidelines of the Preferred Reporting Items for Systematic Reporting and Meta-Analysis. Information on the relevant topic was gathered by searching the PubMed, Scopus, ScienceDirect, and Web of Science databases using keywords, such as "colorectal cancer" AND "phenolic compounds", "colorectal cancer" AND "polyphenol", "colorectal cancer" AND "phenolic acids", "colorectal cancer" AND "flavonoids", "colorectal cancer" AND "stilbene", and "colorectal cancer" AND "lignan" from the reputed peer-reviewed journals published over the last 20 years. Publications that incorporated in vivo experimental designs and produced statistically significant results were considered for this review. Many of these polyphenols demonstrate anti-CRC activities by inhibiting key cellular factors. This inhibition has been demonstrated by antiapoptotic effects, antiproliferative effects, or by upregulating factors responsible for cell cycle arrest or cell death in various in vivo CRC models. Numerous studies from independent laboratories have highlighted different plant phenolic compounds for their anti-CRC activities. While promising anti-CRC activity in many of these agents has created interest in this area, in-depth mechanistic and well-designed clinical studies are needed to support the therapeutic use of these compounds for the prevention and treatment of CRC.

Abstract
Cancerous inhibitor of protein phosphatase 2A (CIP2A), initially reported as a tumor-associated antigen (known as p90), is highly expressed in most solid and hematological tumors. The interaction of CIP2A/p90, protein phosphatase 2A (PP2A), and c-Myc can hinder the function of PP2A toward c-Myc S62 induction, thus stabilizing c-Myc protein, which represents a potential role of CIP2A/p90 in tumorigeneses such as cell proliferation, invasion, and migration, as well as cancer drug resistance. The signaling pathways and regulation networks of CIP2A/p90 are complex and not yet fully understood. Many previous studies have also demonstrated that CIP2A/p90 can be used as a potential therapeutic cancer target. In addition, the autoantibody against CIP2A/p90 in sera may be used as a promising biomarker in the diagnosis of certain types of cancer. In this Review, we focus on recent advances relating to CIP2A/p90 and their implications for future research.

Abstract
Liver cancer is one of the prominent cancer-associated fatal diseases with > 80% of cases befall in low-middle resource nations worldwide. In the current study, we studied the effect of euxanthone (EUX) on obesity-associated liver cancer using a high-fat diet-fed mouse model of diethylnitrosamine (DEN)-provoked hepatocellular carcinoma. Mice with 2 weeks of age were intraperitoneally injected with diethylnitrosamine (DEN) 25 mg/kg b.w. After 4 weeks, the mice were divided into four groups with low-fat diet (LFD), high-fat diet (HFD), and EUX treatment groups with or without PPARγ inhibitor (GW9662). We observed that TIMP3, E-cadherin, and Klotho expressions were downmodulated, while MMP9, ADAM17, and Wnt signalling biofactors (Wnt5a, Wnt3a and β-catenin) were upmodulated in the HFD groups. Nevertheless, these aberrations were reciprocated by the treatment with EUX; at the same time, co-administration of PPARγ inhibitor ablated the anti-cancer effects of EUX, indicating that PPARγ activation is a pivotal mechanism underpinning the negative regulation of oncogenic factors by EUX. Together, these results imply that EUX might be a viable therapeutic option in the treatment of obesity-associated hepatocarcinogenesis.

Abstract
KIAA1524 is the gene encoding the human cancerous inhibitor of PP2A (CIP2A) protein which is regarded as a novel target for cancer therapy. It is overexpressed in 65%-90% of tissues in almost all studied human cancers. CIP2A expression correlates with cancer progression, disease aggressivity in lung cancer besides poor survival and resistance to chemotherapy in breast cancer. Herein, a pan-cancer analysis of public gene expression datasets was conducted showing significant upregulation of CIP2A in cancerous and metastatic tissues. CIP2A overexpression also correlated with poor survival of cancer patients. To determine the non-coding variants associated with CIP2A overexpression, 5'UTR and 3'UTR variants were annotated and scored using RegulomeDB and Enformer deep learning model. The 5'UTR variants rs1239349555, rs1576326380, and rs1231839144 were predicted to be potential regulators of CIP2A overexpression scoring best on RegulomeDB annotations with a high "2a" rank of supporting experimental data. These variants also scored the highest on Enformer predictions. Analysis of the 3'UTR variants of CIP2A predicted rs56255137 and rs58758610 to alter binding sites of hsa-miR-500a-5 and (hsa-miR-3671, hsa-miR-5692a) respectively. Both variants were also found in linkage disequilibrium with rs11709183 and rs147863209 respectively at r2 ≥ 0.8. The aforementioned variants were found to be eQTL hits significantly associated with CIP2A overexpression. Further, analysis of rs11709183 and rs147863209 revealed a high "2b" rank on RegulomeDB annotations indicating a probable effect on DNAse transcription factors binding. The MuTarget analysis indicated that somatic mutations in TP53 are significantly associated with upregulated CIP2A in human cancers. Analysis of missense SNPs on CIP2A solved structure predicted seven deleterious effects. Four of these variants were also predicted as structurally and functionally destabilizing to CIP2A including; rs375108755, rs147942716, rs368722879, and rs367941403. Variant rs1193091427 was predicted as a potential intronic splicing mutation that might be responsible for the novel CIP2A variant (NOCIVA) in multiple myeloma. Finally, Enrichment of the Wnt/β-catenin pathway within the CIP2A regulatory gene network suggested potential of therapeutic combinations between FTY720 with Wnt/β-catenin, Plk1 and/or HDAC inhibitors to downregulate CIP2A which has been shown to be essential for the survival of different cancer cell lines.

Abstract
The way of cell death can be roughly divided into two categories: cell necrosis and PCD(programmed cell death). Pyroptosis is a kind of PCD, its occurrence depends on the gasdermin protein family and it will produce inflammatory response. With constant research in recent years, more and more evidences show that pyroptosis is closely related to the occurrence and development of tumors. The treatment of tumors is a big problem worldwide. We focus on whether we can discover new potential tumor markers and new therapeutic targets from the mechanism. If we can understand the mechanism of pyroptosis and clear the relationship between pyroptosis and the development of tumors, this may provide a new reference for clinical cancer treatment.

Abstract
Gut microbiota bioconversion of polyphenols in predigested mango 'Ataulfo' peel was studied using a validated, dynamic in vitro human colon model (TIM-2) with faecal microbial inoculum. Dried peels were predigested with enzymatic treatment, followed by TIM-2 fermentation (72 h). Samples were taken at 0, 24, 48 and 72 h and analyzed by HPLC-QToF. Derivatives of hydroxyphenylpropionic, hydroxyphenylacetic and hydroxybenzoic acids, as well as, pyrogallol were the main polyphenols identified. These metabolites might derivate from flavonoid (flavanols and flavonols), gallate and gallotannin biotransformation. Despite the high content of ellagic acid in mango peel, low amounts were detected in TIM-2 samples due to transformation into urolythins A and C, mainly. Xanthone and benzophenone derivatives, specific to mango, remained after the colonic biotransformation, contrary to flavonoids, which completely disappeared. In conclusion, microbial-derived metabolites, such as xanthone and benzophenone derivatives, among others, are partially stable after colonic fermentation, and thus have the potential to contribute to mango peel bioactivity.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The genus Polygala, the most representative genus of the Polygalaceae family, comprises more than 600 species from all over the world of which around 40 are distributed in China, some of them, being used in the Traditional Chinese Medicine system. AIM OF THE REVIEW We intend to discuss the current knowledge about the traditional uses, and the newest phytochemical and pharmacological achievements with tentative elucidation of the mechanism of action on the genus Polygala covering the period 2013-2019 to provide a scientific support to the traditional uses, and to critically analyze the reported studies to obtain new insights for further researches. MATERIALS AND METHODS The data were systematically collected from the scientific electronic data bases including SciFinder, Scopus, Elsevier, PubMed and Google Scholar. RESULTS This literature overview reported several traditional uses of different species of Polygala, mainly against wounds, inflammation, cardiovascular and central nervous system disorders. P. altomontana, P caudata, P. flavescens, P. glomerata, P. japonica, P. molluginifolia, P. sibirica, P. tenuifolia are the main species which have been studied in the last few years. Phytochemical studies showed that they contain triterpene saponins, triterpenes, terpenoids, xanthones, flavonoids, coumarins, oligosaccharide esters, styryl-pyrones, benzophenones, and polysaccharides. Pharmacological in vitro and in vivo studies and proposal of the mechanisms of action indicated that pure constituents and extracts of Polygala ssp exhibited significant anti-inflammatory, neuroprotective, antiischemic, antidepressant, sedative, analgesic, antiatherosclerosis, antitumor and enzyme inhibitory properties. CONCLUSION This review on traditional uses and phytopharmacological potential of the genus Polygala revealed updated insights which can be explored for further mechanism-based pharmacological activities and structure/activity relationships studies and a better comprehension of the development of Chinese medicine preparations. However some pharmacological studies showed several gaps such as incomplete methodologies and ambiguous findings. More high scientific quality preclinical studies with pharmacokinetic considerations will be required in the future to assess the traditional uses of some species of this genus. This might lead to efficacy and safety issues in clinical trials and to potential medicinal applications.

Abstract
Glioblastoma is one of the most prevalent primary malignant brain tumors. Glioblastoma often develops resistance to conventional chemoradiotherapy, and thus, new ways to treat glioblastoma are urgently required. The aim of this study was to investigate the effect of euxanthone on the anticancer activities of glioblastoma and its potential mechanism. The U87 and U251 glioblastoma cell lines were cultured in media containing different concentrations of euxanthone. CCK-8 and colony formation assay were used to evaluate the cell proliferation. Cell migration and invasion were evaluated by wound healing and Transwell assays. Flow cytometry was used to assess the cell cycle and apoptosis rate. TUNEL assay was also employed to evaluate the apoptosis rate. Gene and protein expressions were determined by RT-qPCR and western blotting, respectively. A xenograft model was established to evaluate the efficacy of euxanthone in vivo. Euxanthone significantly repressed cell viability, migration, invasion, and epithelial-to-mesenchymal transition of U87 and U251 cells; and increased the rate of apoptosis. Western blotting results revealed that the levels of p21, p27, cleaved caspase-3, Bax, TIMP-3, and E-cadherin were upregulated while, the levels of CDK4, CDK6, pro-caspase-3, Bcl-2, MMP-2, MMP-9, N-cadherin, and Vimentin were downregulated by euxanthone. In addition, the expression of p-STAT3 was decreased, while the expression of SHP-1 was upregulated by euxanthone. We proposed that euxanthone could repress the malignant behavior of glioblastoma cells through suppression of STAT3 phosphorylation and activation of SHP-1. Further, in vivo data demonstrated that euxanthone repressed tumor growth and promoted apoptosis.

Hu Q, Zhou S, Hu X, Zhang H, Huang S, Wang Y. Systematic screening identifies a 2-gene signature as a high-potential prognostic marker of undifferentiated pleomorphic sarcoma/myxofibrosarcoma. J Cell Mol Med 2019; 24:1010-1021. [PMID: 31742892 PMCID: PMC6933343 DOI: 10.1111/jcmm.14814] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2019] [Revised: 09/29/2019] [Accepted: 10/27/2019] [Indexed: 02/05/2023] Open
Abstract
The Cancer Genome Atlas (TCGA) Research Network confirmed that undifferentiated pleomorphic sarcoma (UPS) and myxofibrosarcoma (MFS) share a high level of genomic similarities and fall into a single spectrum of tumour. However, no molecular prognostic biomarkers have been identified in UPS/MFS. In this study, by extracting data from TCGA-Sarcoma (SARC), we explored relapse-related genes, their prognostic value and possible mechanisms of the dysregulations. After systematic screening, ITGA10 and PPP2R2B were included to construct a 2-gene signature. The 2-gene signature had an AUC value of 0.83 and had an independent prognostic value in relapse-free survival (RFS) (HR: 2.966, 95%CI: 1.995-4.410 P < .001), and disease-specific survival (DSS) (HR: 2.283, 95%CI: 1.358-3.835, P = .002), as a continuous variable. Gene-level copy number alterations (CNAs) were irrelevant to their dysregulation. Two CpG sites (cg15585341 and cg04126335) around the promoter of ITGA10 showed strong negative correlations with ITGA10 expression (Pearson's r < -0.6). Transcript preference was observed in PPP2R2B expression. The methylation of some CpG sites in two gene body regions showed at least moderate positive correlations (Pearson's r > .4) with PPP2R2B expression. Besides, the 2-gene signature showed a moderate negative correlation with CD4 + T cell infiltration. High-level CD4 + T cell infiltration and neutrophil infiltration were associated with significantly better RFS. Based on these findings, we infer that the 2-gene signature might be a potential prognostic marker in patients with UPS/MFS. Considering the potential benefits of immunotherapy for UPS/MFS patients, it is imperative to explore the predictive value of this signature in immunotherapeutic responses in the future.

Abstract
Non-small-cell lung cancer (NSCLC) is one of the most common human malignancies. Amentoflavone (AF) is one of bioflavonoid compounds isolated from Selaginella tamariscina Spring. This study was designed to examine the effect of AF on NSCLC. Our results indicated that AF decreased cell viability of both H1299 and H358 cells. Colony formation assay also showed that AF was able to suppress the anchorage-independent growth of NSCLC cells. AF also triggered cell cycle arrest by downregulating cyclin D1, CDK4, and CDK6. The pro-apoptotic activity of AF was confirmed by Hoechst staining and flow cytometry. The effect of AF on activation of caspase-3, upregulation of Bax, and downregulation of Bcl-2 was examined by western blot. The anti-growth and pro-apoptotic activities of AF were further validated in xenograft murine model. iTRAQ assay showed that cancerous inhibitor of PP2A (CIP2A) expression was markedly downregulated by AF treatment in H1299 cells. In addition, qRT-PCR and western blot also showed that AF was able to dose-dependently inhibit CIP2A expression. Meanwhile, the activity of protein phosphatase 2A (PP2A) was enhanced by AF treatment. The mRNA and protein expression of CIP2A as well as PP2A activity in xenograft tumor tissue were examined, which indicated that the in vivo anticancer activity of AF was associated with downregulation of CIP2A and reactivation of PP2A. Moreover, our results showed that the anti-growth and pro-apoptotic activities of AF were augmented by CIP2A knockdown and attenuated by ectopic CIP2A expression. Our results indicated that AF exhibited anticancer activity in NSCLC by targeting CIP2A. Anat Rec, 302:2201-2210, 2019. © 2019 American Association for Anatomy.

Abstract
BACKGROUND Furowanin A (Fur A) is a flavonoid compound isolated from medicinal plant Millettia pachycarpa Benth. This study aims to explore the effect of Fur A on Colorectal cancer (CRC) and its molecular mechanisms. METHODS Cell proliferative capacity of CRC cells was assessed by CCK-8 assay. Cell apoptosis and cell cycle distribution were detected by flow cytometry. Cell migration and invasion were detected by wound healing and Transwell assay, respectively. EMT markers, apoptosis and profilin 1(Pfn1) expression were detected by immunohistochemistry (IHC). The protein expression levels were examined by western blotting. i-TRAQ analyses were conducted to identify the differentially expressed genes in CRC cells. CRC xenograft model was also used to validate the in vivo anti-cancer activity of Fur A. RESULTS Fur A exhibited anti-prolifertive, blocked cell cycle progression and promoted apoptotic cell death in CRC cells. Fur A suppressed the migration, invasion and epithelial-to-mesenchymal transition (EMT) in vitro, and tumor growth and pulmonary metastasis in vivo, without causing obvious toxicity. iTRAQ analysis identified Pfn1 as a gene up-regulated by Fur A. In xenograft tumor tissue, the expression of Pfn1 was also elevated by Fur A treatment. In clinical CRC samples, high expression of Pfn1 was correlated with lower stage and longer survival. Knockdown of Pfn1 significantly dampened the pro-apoptotic and anti-metastatic activities of Fur A in CRC cells. Ectopic Pfn1 expression augmented the anti-neoplastic activities of Fur A. CONCLUSION Fur A exhibited anti-cancer activities in vitro and in vivo in CRC by up-regulating Pfn1.

Abstract
AIMS Colorectal Cancer (CRC) accounts for 6.1% incidence and 9.2% mortality worldwide. The current study aimed to investigate the effect of alpinumisoflavone (AIF) on CRC and its possible molecular mechanism. METHODS HCT-116 and SW480 cells were chosen as cell model to study the anti-cancer activity of AIF in vitro experiments. Cells proliferative capacity and clonogenicity were examined by CCK-8 assay and colony formation assay, while cell apoptosis was detected by Hoechst 33258 staining and Flow cytometer. The protein expression levels of related gene were examined by western blotting. Transcriptome analyses were conducted to identify the differentially expressed genes in CRC cells, following AIF treatment. DNA damage was examined by γH2AX foci assay. The anti-cancer effect of AIF in vivo was validated in CRC xenograft model. KEY FINDINGS We found that AIF inhibited CRC cell proliferation and promoted apoptosis in a dose-dependent manner, as well as increased the number of γ-H2AX foci. In addition, microarray analysis showed that the DNA-double strand break (DSB) repair gene RAD51 was aberrantly overexpressed in CRC tissues, and was positively correlated with lymph node metastasis, TNM stage and poor outcomes. Both in vitro and in vivo experiments confirm that AIF treatment significantly decreased RAD51 levels. Knockdown RAD51 could enhance the anti-cancer activity of AIF against CRC, while abrogated by RAD51 overexpression. SIGNIFICANCE These findings suggest that AIF can be regarded as a potential anti-cancer drug and provide new insights into CRC treatment.

Abstract
The role of phytochemicals as potential prodrugs or therapeutic substances against tumors has come in the spotlight in the very recent years, thanks to the huge mass of encouraging and promising results of the in vitro activity of many phenolic compounds from plant raw extracts against many cancer cell lines. Little but important evidence can be retrieved from the clinical and nutritional scientific literature, where flavonoids are investigated as major pro-apoptotic and anti-metastatic compounds. However, the actual role of these compounds in cancer is still far to be fully elucidated. Many of these phytochemicals act in a pleiotropic and poorly specific manner, but, more importantly, they are able to tune the reactive oxygen species (ROS) signaling to activate a survival or a pro-autophagic and pro-apoptosis mechanism, depending on the oxidative stress-responsive endowment of the targeted cell. This review will try to focus on this issue.
