Abstract
Resveratrol, a natural product, has demonstrated anti-tumor effects in various kinds of tumor types, including colon, breast, and pancreatic cancers. Most research has focused on the inhibitory effects of resveratrol on tumor cells themselves rather than resveratrol’s effects on tumor immunology. In this study, we found that resveratrol inhibited the growth of lung adenocarcinoma in a subcutaneous tumor model by using the β-cyclodextrin-resveratrol inclusion complex. After resveratrol treatment, the proportion of M2-like tumor-associated macrophages (TAMs) was reduced and tumor-infiltrating CD8T cells showed significantly increased activation. The results of co-culture and antibody neutralization experiments suggested that macrophage-derived IL-18 may be a key cytokine in the resveratrol anti-tumor effect of CD8T cell activation. The results of this study demonstrate a novel view of the mechanisms of resveratrol tumor suppression. This natural product could reprogram TAMs and CD8T effector cells for tumor treatment.

Abstract
The Wnt signaling pathway controls multiple events during embryonic development of multicellular animals and is carcinogenic when aberrantly activated in adults. Breast cancer and triple-negative breast cancer (TNBC) in particular depend upon Wnt pathway overactivation. Despite this importance, no Wnt pathway-targeting drugs are currently available, which necessitates novel approaches to search for therapeutically relevant compounds targeting this oncogenic pathway. Stilbene analogs represent an under-explored field of therapeutic natural products research. In the present work, a library of complex stilbene derivatives was obtained through biotransformation of a mixture of resveratrol and pterostilbene using the enzymatic secretome of Botrytis cinerea. To improve the chemodiversity, the reactions were performed using i-PrOH, n-BuOH, i-BuOH, EtOH, or MeOH as cosolvents. Using this strategy, a series of 73 unusual derivatives was generated distributed among 6 scaffolds; 55 derivatives represent novel compounds. The structure of each compound isolated was determined by nuclear magnetic resonance and high-resolution mass spectrometry. The inhibitory activity of the isolated compounds against the oncogenic Wnt pathway was comprehensively quantified and correlated with their capacity to inhibit the growth of the cancer cells, leading to insights into structure-activity relationships of the derivatives. Finally, we have dissected mechanistic details of the stilbene derivatives activity within the pathway.

Anticancer Agents Med Chem 2021; 20:1105-1114. [PMID: 32238142 DOI: 10.2174/1871520620666200402080034] [Citation(s) in RCA: 26] [Impact Index Per Article: 8.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2019] [Revised: 12/10/2019] [Accepted: 02/18/2020] [Indexed: 01/06/2023]
Abstract
BACKGROUND Gastric Cancer (GC) is one of the most malignant and lethal tumors worldwide. The hypoxic microenvironment is correlated with GC cell invasion, metastasis and Epithelial-Mesenchymal Transition (EMT). Resveratrol is a compound extracted from various plants, including grapes, berries, and some traditional Chinese medicines. Recently, the anticancer properties of resveratrol against many cancers have been reported in a range of studies. However, the exact mechanism through which resveratrol prevents GC invasion and metastasis under hypoxic conditions remains unclear. OBJECTIVE The objective of this study is to show to what extent resveratrol could inhibit the hypoxia-induced malignant biological behavior of GC. METHODS SGC-7901 cells were cultured in a consistent 3% O2 hypoxic condition or 21% O2 normal condition for 48 hours to establish an in vitro hypoxia model. Western blot and qRT-PCR were used to detect EMT markers of SGC- 7901 cells, including E-cadherin, HIF-1a, Vimentin, etc. Transwell Matrigel Invasion Assays were used to test the invasive ability of SGC-7901 cells. The siRNA targeting Gli-1 showed its role in hypoxia-induced EMT and invasion of SGC-7901 cells. RESULTS Resveratrol was found to significantly decrease HIF-1α protein levels induced by hypoxia in SGC-7901 cells. HIF-1α accumulation was found to promote cell proliferation, migration, and invasive capacities in addition to EMT changes through the activation of the Hedgehog pathway. These effects were found to be reversed by resveratrol. CONCLUSION Therefore, these data indicate that resveratrol may serve as a potential anticancer agent for the treatment of GC, even in a hypoxic tumor microenvironment.

Abstract
Gastric cancer (GC) is one of the most common cancers with high malignancy. In spite of the great development in diagnostic tools and application of anti-tumor drugs, we have not witnessed a significant increase in the survival time of patients with GC. Multiple studies have revealed that Wnt, Nrf2, MAPK, and PI3K/Akt signaling pathways are involved in GC invasion. Besides, long non-coding RNAs and microRNAs function as upstream mediators in GC malignancy. GC cells have acquired resistance to currently applied anti-tumor drugs. Besides, combination therapy is associated with higher anti-tumor activity. Resveratrol (Res) is a non-flavonoid polyphenol with high anti-tumor activity used in treatment of various cancers. A number of studies have demonstrated the potential of Res in regulation of molecular pathways involved in cancer malignancy. At the present review, we show that Res targets a variety of signaling pathways to induce apoptotic cell death and simultaneously, to inhibit the migration and metastasis of GC cells.

Abstract
Gastrointestinal (GI) cancer is one of the leading causes of cancer-related deaths worldwide. According to the Global Cancer Statistics, colorectal cancer is the second leading cause of cancer-related mortality, closely followed by gastric cancer (GC). Environmental, dietary, and lifestyle factors including cigarette smoking, alcohol intake, and genetics are the most important risk factors for GI cancer. Furthermore, infections caused by Helicobacter pylori are a major cause of GC initiation. Despite improvements in conventional therapies, including surgery, chemotherapy, and radiotherapy, the length or quality of life of patients with advanced GI cancer is still poor because of delayed diagnosis, recurrence and side effect. Resveratrol (3, 4, 5-trihydroxy-trans-stilbene; Res), a natural polyphenolic compound, reportedly has various pharmacologic functions including anti-oxidant, anti-inflammatory, anti-cancer, and cardioprotective functions. Many studies have demonstrated that Res also exerts a chemopreventive effect on GI cancer. Research investigating the anti-cancer mechanism of Res for the prevention and treatment of GI cancer has implicated multiple pathways including oxidative stress, cell proliferation, and apoptosis. Therefore, this paper provides a review of the function and molecular mechanisms of Res in the prevention and treatment of GI cancer.

Abstract
Objectives: Protein phosphatase 2A (PP2A), a major serine/threonine
phosphatase, is also known to be a target of ROS. The methylation of PP2A can be
catalyzed by leucine carboxyl methyltransferase-1 (LCMT1), which regulates PP2A
activity and substrate specificity. Methods: In the previous study, we have showed that LCMT1-dependent
PP2Ac methylation arrests H2O2-induced cell oxidative
stress damage. To explore the possible protective mechanism, we performed
iTRAQ-based comparative quantitative proteomics and phosphoproteomics studies of
H2O2-treated vector control and LCMT1-overexpressing
cells. Results: A total of 4480 non-redundant proteins and 3801 unique
phosphopeptides were identified by this means. By comparing the
H2O2-regulated proteins in LCMT1-overexpressing and
vector control cells, we found that these differences were mainly related to
protein phosphorylation, gene expression, protein maturation, the cytoskeleton
and cell division. Further investigation of LCMT1 overexpression-specific
regulated proteins under H2O2 treatment supported the idea
that LCMT1 overexpression induced ageneral dephosphorylation of proteins and
indicated increased expression of non-erythrocytic hemoglobin, inactivation of
MAPK3 and regulation of proteins related to Rho signal transduction, which were
known to be linked to the regulation of the cytoskeleton. Discussion: These data provide proteomics and phosphoproteomics
insights into the association of LCMT1-dependent PP2Ac methylation and oxidative
stress and indirectly indicate that the methylation of PP2A plays an important
role against oxidative stress.

Abstract
Bronchoconstrictive airway disorders such as asthma are characterized by inflammation and increases in reactive oxygen species (ROS), which produce a highly oxidative environment. β2-adrenergic receptor (β2AR) agonists are a mainstay of clinical therapy for asthma and provide bronchorelaxation upon inhalation. We have previously shown that β2AR agonism generates intracellular ROS, an effect that is required for receptor function, and which post-translationally oxidizes β2AR cysteine thiols to Cys-S-sulfenic acids (Cys-S-OH). Furthermore, highly oxidative environments can irreversibly oxidize Cys-S-OH to Cys-S-sulfinic (Cys-SO2H) or S-sulfonic (Cys-SO3H) acids, which are incapable of further participating in homeostatic redox reactions (i.e., redox-deficient). The aim of this study was to examine the vitality of β2AR-ROS interplay and the resultant functional consequences of β2AR Cys-redox in the receptors native, oxidized, and redox-deficient states. Here, we show for the first time that β2AR can be oxidized to Cys-S-OH in situ, moreover, using both clonal cells and a human airway epithelial cell line endogenously expressing β2AR, we show that receptor redox state profoundly influences β2AR orthosteric ligand binding and downstream function. Specifically, homeostatic β2AR redox states are vital toward agonist-induced cAMP formation and subsequent CREB and G-protein-dependent ERK1/2 phosphorylation, in addition to β-arrestin-2 recruitment and downstream arrestin-dependent ERK1/2 phosphorylation and internalization. On the contrary, redox-deficient β2AR states exhibit decreased ability to signal via either Gαs or β-arrestin. Together, our results demonstrate a β2AR-ROS redox axis, which if disturbed, interferes with proper receptor function.

Abstract
The seeds of tree peony (Paeonia ostii) are promulgated as emerging edible oil crops. However, biological properties of principal constituents of peony seeds were not well studied. Fifteen main constituents including suffruticosols A and B, trans-ε-viniferin, ampelopsin E, resveratrol, trans-resveratrol-4'-O-β-d-glucopyranoside, paeoniflorin, luteolin, luteolin-4'-O-β-d-glucopyranoside, apigenin, kaempferol, oleanic acid, betulinic acid, hederagenin, and caffeic acid were isolated and identified. Their cytotoxicity against human tumor cell lines (COLO205, HT-29, HepG2, AGS, and HL-60) were evaluated. Among them, trans-ε-viniferin showed the most potent cytotoxicity against HL-60 cells (IC50 5.6 μM); ampelopsin E exhibited the most obvious antiproliferative properties on COLO205 (IC50 78.1 μM) and HT-29 (IC50 4.2 μM) cells, and betulinic acid showed the strongest growth inhibitory effects on HepG2 (IC50 6.6 μM) and AGS (IC50 5.4 μM) cells. Three enzymes (tyronsinase, α-glucosidase, and acetylcholinesterase) inhibitory activities of 12 compounds were also screened. Stilbene compounds, especially suffruticosols A and B, showed a significant inhibitory activity on all three enzymes. PRACTICAL APPLICATIONS: The cytotoxicity of 15 main constituents from peony seeds against COLO205, HT-29, HepG2, AGS, and HL-60 cells were evaluated. Among them, trans-ε-viniferin showed the most potent cytotoxicity against HL-60 cells (IC50 5.6 μM); ampelopsin E exhibited the most obvious antiproliferative properties on COLO205 (IC50 78.1 μM) and HT-29 (IC50 4.2 μM) cells, and betulinic acid showed the strongest growth inhibitory effects on HepG2 (IC50 6.6 μM) and AGS (IC50 5.4 μM) cells. Collectively, these results suggested that Paeonia ostii seed (POS) extracts are potential candidates for anticancer agents.

Abstract
BACKGROUND Activated hepatic stellate cell (aHSC) play a critical role in hepatocellular carcinoma (HCC) progression crosstalking with cancer cell via various signaling pathways. The aim of our study is to explore the tumor-promoting effects of aHSCs on HCC via ERK pathway. METHODS α-SMA, p-ERK and p-JNK expression levels in tumoral and peritumoral tissues of HCC were assessed by immunohistochemical and western blotting. The protein and mRNA expression levels in human hepatoma cell treated with aHSC conditioned medium (CM) were determined by western blotting and real-time quantitative PCR, respectively. Cell migration and invasion abilities were assessed using transwell assays. The proliferation ability of HCC cells induced by aHSCs-CM was detected by CCK-8 assay and cell cycle analysis. RESULTS We found that aHSC number was positively correlated with p-ERK expression levels in tumoral tissues and aHSC-CM could time-dependently promote PCNA, p-ERK expression in HCC cells. Moreover, aHSC-CM enhanced HCC cells proliferation via ERK. Additionally, aHSC upregulated c-jun and cyclinD1 expression levels, accelerating the transition from G1 to the S phase of HCC cells, and this effect could be arrested by inhibiting ERK pathway. Furthermore, aHSC-CM promoted migration and invasion of HCC cells via ERK. Epithelial-mesenchymal transitions (EMT) phenomenon could be reversed by ERK suppression. CONCLUSION High expression of p-ERK and aHSCs may be associated with the aggressive behavior of HCC cells. Secretions from aHSCs could promote proliferation and EMT of HCC cells via ERK1/2/c-jun/cyclinD1 axis or ERK pathway.

Abstract
Gastric cancer (GC) is the fourth most common cancer and the second leading cause of cancer-related mortality in the world. Late diagnosis and classical therapeutic approaches such as surgery, chemotherapy and radiotherapy make this disease a still threatening tumor. Genetic asset, environmental stress, dietary habit and infections caused by Helicobacter pylori (H. pylori) are the major causes concurring to GC initiation. A common mechanism is induction of radicals resulting in gastric mucosal injury. A regular food intake of antioxidant and radical scavenging agents has been proposed to exert protection against tumorigenesis. Resveratrol belongs to the polyphenol flavonoids class of antioxidants produced by a restricted number of plants. Resveratrol exerts bactericidal activity against H. pylori and is a powerful antioxidant, thus acting as a tumor preventive agent. Resveratrol intracellular signaling results in growth arrest and apoptosis, so that it can be directed against tumor progression. Resveratrol therapeutic potential against GC initiation and progression are reviewed here.

Abstract
A ligand of peroxisome proliferator-activated receptor γ (PPARγ), 15-deoxy-Δ(12,14)-prostaglandin J2 (15d-PGJ2) induces apoptosis in various cells. However, the mechanism appears to be complex and cell-type specific. We investigated the mechanism of 15d-PGJ2-induced apoptosis of rabbit synovial cells. Exposure to 15d-PGJ2 resulted in DNA fragmentation accompanied by caspase-3 and -9 activations in the cells, suggesting occurrence of mitochondria-mediated apoptosis. Although the exposure also induced remarkable increase in p53 protein, its transcriptional activity was rather reduced, suggesting non-necessity of p53 in 15d-PGJ2-induced apoptosis. Covalent binding of 15d-PGJ2 to cellular proteins including p53 resulted in their insolubilization. N-acetylcysteine inhibited not only the 15d-PGJ2-induced apoptotic events but also the protein insolubilizations via its interaction with 15d-PGJ2. The studies using a PPARγ-agonist and -antagonist showed noninvolvement of PPARγ in 15d-PGJ2-induced apoptosis. The pre-exposure to pro-inflammatory cytokines did not affect the cytotoxicity of 15d-PGJ2 in synovial cells. Taken together, these results show that 15d-PGJ2 induces a mitochondria-mediated apoptotic pathway in p53- and PPARγ-independent manners.

Abstract
Fucoidan is a sulfated polysaccharide present in brown algae that has been identified to exhibit multiple biological effects. In this study, the apoptotic effects of fucoidan in MC3 human mucoepidermoid carcinoma (MEC) cells were investigated. The apoptotic effects of fucoidan on MC3 MEC cells were evaluated by cell proliferation assay, 4′,6-diamidino-2-phenylindole staining and western blot analysis. The results showed that fucoidan decreased cell proliferation and induced caspase-dependent apoptosis in MC3 MEC cells. Fucoidan downregulated the phosphorylation of extracellular signal-regulated kinase (ERK) 1/2, whereas phospho-p38 mitogen-activated protein kinase or phospho-c-Jun NH2-terminal kinase (JNK) levels were not altered. In addition, fucoidan significantly decreased the expression levels of myeloid cell leukemia-1 (Mcl-1). These results suggest that fucoidan is able to modulate the ERK1/2 pathway and thereby regulate Mcl-1 protein expression and induce apoptosis in MC3 MEC cells. Therefore, fucoidan may be a promising agent for the treatment of human MEC.

Abstract
Cancer is one of the leading causes of death worldwide. Commonly used cancer treatments, including chemotherapy and radiation therapy, often have side effects and a complete cure is sometimes impossible. Therefore, prevention, suppression, and/or delaying the onset of the disease are important. The onset of gastroenterological cancers is closely associated with an individual’s lifestyle. Thus, changing lifestyle, specifically the consumption of fruits and vegetables, can help to protect against the development of gastroenterological cancers. In particular, naturally occurring bioactive compounds, including curcumin, resveratrol, isothiocyanates, (-)-epigallocatechin gallate and sulforaphane, are regarded as promising chemopreventive agents. Hence, regular consumption of these natural bioactive compounds found in foods can contribute to prevention, suppression, and/or delay of gastroenterological cancer development. In this review, we will summarize natural phytochemicals possessing potential antioxidant and/or anti-inflammatory and anti-carcinogenic activities, which are exerted by regulating or targeting specific molecules against gastroenterological cancers, including esophageal, gastric and colon cancers.

Abstract
Trans-3,4',5-trihydroxystilbene (resveratrol) is a grape polyphenol present in various plants, food products, red wine and grapes. Resveratrol has anti-inflammatory, anticarcinogenic, anti-oxidant and anti-aging properties. Matrix metalloproteinases (MMPs) are key enzymes involved in the degradation of the extracellular matrix, and their expression may be regulated in cancer metastasis. In the present study, we aimed to evaluate the effect of resveratrol on MMPs and cell migration, and to understand the mechanism of action in HT1080 human fibrosarcoma cells. We found that resveratrol inhibited HT1080 cell viability at various concentrations as detected by the MTT assay and FACS analysis. However, resveratrol dramatically increased the activation and expression of MMP-9 in a dose- and time-dependent manner, as determined by gelatin zymography assay and western blot analysis. We also discovered that resveratrol enhanced the migratory ability of HT1080 cells, as determined by the wound healing assay, and decreased the phosphorylation of p38 kinase. Moreover, the Akt kinase was inhibited by resveratrol in the HT1080 cells. The inhibition of p38 and Akt kinases with SB203580 and LY294002 further increased resveratrol-induced MMP-9 as well as cell migration in the HT1080 cells. Our results suggest that resveratrol regulates MMP-9 and migratory abilities through the p38 kinase and PI-3K pathways in HT1080 human fibrosarcoma cells.

Abstract
The currently available chemotherapeutic regimens against gastric cancer are not very effective, leading to high recurrence and poor survival. Resveratrol is a naturally occurring polyphenol with potent apoptosis-inducing activity. However, the mechanism underlying its actions remains unknown. In the present study, human gastric adenocarcinoma SGC7901 cells were treated with resveratrol (0, 25, 50, 100 and 200 μmol/L) for 48 h, and cellular apoptosis DNA damage were determined. In certain experiments, cells were incubated with superoxide dismutase (100 U/mL), catalase (300 U/mL) or sirtinol (10 μmol/L) to determine the role of reactive oxygen species (ROS) and sirtuin1 in resveratrol-induced cellular apoptosis. Treatment with resveratrol (50-200 μmol/L) for 48 h significantly induced apoptosis and DNA damage in human gastric cancer SGC7901 cells. This was due to the increased generation of ROS following resveratrol treatment because incubation of cells with superoxide dismutase (100 U/mL) or catalase (300 U/mL) attenuated resveratrol-induced cellular apoptosis. Interestingly, treatment with resveratrol (25-200 μmol/L) did not affect the level and activity of sirtuin1, whereas the sirtuin1 inhibitor sirtinol (10 μmol/L) significantly reduced sirtuin1 activity. Furthermore, treatment with sirtinol (10 μmol/L) did not have any effect on apoptosis induced by resveratrol. These data provide evidence that resveratrol induces apoptosis via ROS, but independent of sirtuin1, in the human gastric cancer cell line SGC7901.

Abstract
Mitochondrial activity progressively declines during ageing and in many neurodegenerative diseases. Caloric restriction (CR) has been suggested as a dietary intervention that is able to postpone the detrimental aspects of aging as it ameliorates mitochondrial performance. This effect is partially due to increased mitochondrial biogenesis. The nutrient-sensing PGC-1α is a transcriptional coactivator that promotes the expression of mitochondrial genes and is induced by CR. It is believed that many of the mitochondrial and metabolic benefits of CR are due to increased PGC-1α activity. The increase of PGC-1α is also positively linked to neuroprotection and its decrement has been involved in the pathogenesis of many neurodegenerative diseases. This paper aims to summarize the current knowledge about the role of PGC-1α in neuronal homeostasis and the beneficial effects of CR on mitochondrial biogenesis and function. We also discuss how PGC-1α-governed pathways could be used as target for nutritional intervention to prevent neurodegeneration.

Abstract
Liver cancer ranks in prevalence and mortality among top five cancers worldwide. Accumulating interests have been focused in developing new strategies for liver cancer treatment. We have previously showed that dihydroartemisinin (DHA) exhibited antitumor activity towards liver cancer. In this study, we demonstrated that histone deacetylase inhibitors (HDACi) significantly augmented the antineoplastic effect of DHA via increasing apoptosis in vitro and in vivo. Inhibition of ERK phosphorylation contributed to DHA-induced apoptosis, due to the fact that inhibitor of ERK phosphorylation (PD98059) increased DHA-induced apoptosis. Compared with DHA alone, the combined treatment with DHA and HDACi reduced mitochondria membrane potential, released cytochrome c into cytoplasm, increased p53 and Bak, decreased Mcl-1 and p-ERK, activated caspase 3 and PARP, and induced apoptotic cells. Furthermore, we showed that HDACi pretreatment facilitated DHA-induced apoptosis. In Hep G2-xenograft carrying nude mice, the intraperitoneal injection of DHA and SAHA resulted in significant inhibition of xenograft tumors. Results of TUNEL and H&E staining showed more apoptosis induced by combined treatment. Immunohistochemistry data revealed the activation of PARP, and the decrease of Ki-67, p-ERK and Mcl-1. Taken together, our data suggest that the combination of HDACi and DHA offers an antitumor effect on liver cancer, and this combination treatment should be considered as a promising strategy for chemotherapy.

Abstract
Resveratrol (trans-3,5,4'-trihydroxystilbene), a polyphenol found in red wine, has multiple beneficial activities that are similar to caloric restriction. In this study, we analyzed the effect of resveratrol on the gonadotropin genes, follicle-stimulating hormone (FSHβ) and luteinizing hormone (LHβ) in LβT2 immortalized mouse gonadotrope cells. Resveratrol specifically inhibited activin-induced FSHβ mRNA and protein expression, and reduced activin-stimulated Smad2/3 phosphorylation. Knockdown of SirT1 gene expression or SirT1 inhibition did not block repression of FSHβ expression or suppression of Smad2/3 phosphorylation, but did increase p53 acetylation. Taken together, our results suggest that resveratrol down-regulates Smad2/3 phosphorylation and suppresses FSHβ expression via a SirT1-independent pathway.

Abstract
Autophagy that is induced by starvation or cellular stress can enable cancer cell survival by sustaining energy homeostasis and eliminating damaged organelles and proteins. In response to stress, cancer cells have been reported to accumulate the protein p62/SQSTM1 (p62), but its role in the regulation of autophagy is controversial. Here, we report that the plant phytoalexin resveratrol (RSV) triggers autophagy in imatinib-sensitive and imatinib-resistant chronic myelogenous leukemia (CML) cells via JNK-dependent accumulation of p62. JNK inhibition or p62 knockdown prevented RSV-mediated autophagy and antileukemic effects. RSV also stimulated AMPK, thereby inhibiting the mTOR pathway. AMPK knockdown or mTOR overexpression impaired RSV-induced autophagy but not JNK activation. Lastly, p62 expression and autophagy in CD34+ progenitors from patients with CML was induced by RSV, and disrupting autophagy protected CD34+ CML cells from RSV-mediated cell death. We concluded that RSV triggered autophagic cell death in CML cells via both JNK-mediated p62 overexpression and AMPK activation. Our findings show that the JNK and AMPK pathways can cooperate to eliminate CML cells via autophagy.

Abstract
BACKGROUND AND PURPOSE Resveratrol (RES) has been shown to prolong lifespan and prevent cancer formation. At present, the precise cellular mechanisms of RES actions are still not clearly understood, and this is the focus of this study. EXPERIMENTAL APPROACH Using human hepatocellular carcinoma-derived HepG2 cells as a model, we studied RES-induced changes in cell growth, cell cycle progression and apoptosis. KEY RESULTS RES at lower concentrations induced a strong but reversible S-phase delay and mild DNA synthesis inhibition, yet without causing apoptotic or necrotic cell death. At high concentrations, RES induced apoptosis, which is mainly mediated by the mitochondrial pathway. Overall, RES was a relatively weak apoptotic agent. Mechanistically, MEK inhibition was identified as an important early signalling event for RES-induced apoptosis. In comparison, activation of CDK2 and checkpoint kinase 2, and inhibition of phosphatidylinositol 3'-kinase/Akt signalling pathway contributed to the induction by RES of a reversible, non-cytotoxic S-phase delay. CONCLUSION AND IMPLICATIONS It is hypothesized that the induction of a non-cytotoxic S-phase delay may represent a useful mechanistic strategy for lifespan prolongation and cancer prevention. When cell cycles are selectively slowed down in the S phase, it would cumulatively increase the total lifespan of an organism if the total numbers of cell divisions of a given organism are assumed to remain basically constant. Likewise, when cells proceed through the cell cycles at a reduced pace during DNA replication, it may allow cells more time to repair the damaged DNA, and thereby reduce the chances for mutagenesis and tumour initiation.
