Abstract
BACKGROUND/AIM Melanoma is a prevalent malignant tumor that arises from melanocytes. The treatment of malignant melanoma has become challenging due to the development of drug resistance. It is, therefore, imperative to identify novel therapeutic drug candidates for controlling malignant melanoma. Naringenin is a flavonoid abundant in oranges and other citrus fruits and recognized for its numerous medicinal benefits. The objective of the study was to assess the anti-carcinogenic potential of naringenin by evaluating its ability to regulate the cellular production of reactive oxygen species (ROS) and its effect on mitochondrial function and apoptosis in melanoma cells. MATERIALS AND METHODS Cell viability, intracellular ROS levels, cell apoptosis, and mitochondrial functions were evaluated. RESULTS Naringenin decreased melanoma cell viability and triggered generation of ROS, leading to cell apoptosis. In addition, it stimulated mitochondrial damage in melanoma cells by elevating the levels of Ca2+ and ROS in the mitochondria and decreasing cellular ATP. Naringenin stimulated the expression of proapoptotic proteins, including phospho p53, B-cell lymphoma-2 (Bcl-2)-associated X protein, cleaved caspase-3, and cleaved caspase-9, in melanoma cells in a time-dependent manner. Furthermore, it reduced the expression of the anti-apoptotic protein Bcl-2. Naringenin triggered cell apoptosis by phosphorylating c-Jun N-terminal kinase and stimulating cellular autophagy. CONCLUSION Naringenin caused oxidative stress and mitochondrial damage, and activated autophagy in melanoma cells, leading to cell apoptosis. These findings indicate the potential of naringenin as a new therapeutic candidate for melanoma.

Abstract
People with obesity maintain low levels of inflammation; therefore, their exposure to foreign antigens can trigger an excessive immune response. In people with obesity or allergic contact dermatitis (ACD), symptoms are exacerbated by a reduction in the number of regulatory T cells (Tregs) and IL-10/TGF-β-modified macrophages (M2 macrophages) at the inflammatory site. Benefits of intermittent fasting (IF) have been demonstrated for many diseases; however, the immune responses regulated by macrophages and CD4+T cells in obese ACD animal models are poorly understood. Therefore, we investigated whether IF suppresses inflammatory responses and upregulates the generation of Tregs and M2 macrophages in experimental ACD animal models of obese mice. The IF regimen relieved various ACD symptoms in inflamed and adipose tissues. We showed that the IF regimen upregulates Treg generation in a TGF-β-dependent manner and induces CD4+T cell hypo-responsiveness. IF-M2 macrophages, which strongly express TGF-β and inhibit CD4+T cell proliferation, directly regulated Treg differentiation from CD4+T cells. These results indicate that the IF regimen enhances the TGF-β-producing ability of M2 macrophages and that the development of Tregs keeps mice healthy against ACD exacerbated by obesity. Therefore, the IF regimen may ameliorate inflammatory immune disorders caused by obesity.

Abstract
AIM The prevalence of metabolic syndrome (MetS), a cluster of serious medical conditions that raise the risk of lung cancer, has increased worldwide. Tobacco smoking (TS) potentially increases the risk of developing MetS. Despite the potential association of MetS with lung cancer, preclinical models that mimic human diseases, including TS-induced MetS, are limited. Here we evaluated the impact of exposure to tobacco smoke condensate (TSC) and two representative tobacco carcinogens, 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNK) and benzo[a]pyrene (BaP), on MetS development in mice. MATERIALS AND METHODS FVB/N or C57BL/6 mice were exposed to vehicle, TSC, or NNK and BaP (NB) twice weekly for 5 months. The serum levels of total cholesterol (TCHO), triglycerides, high-density lipoprotein (HDL), blood glucose, and metabolites, along with glucose tolerance and body weight, were measured. KEY FINDINGS Compared with those of vehicle-treated mice, mice with TSC or NB exposure displayed major phenotypes associated with MetS, including increased serum levels of TCHO, triglycerides, and fasting and basal blood glucose and decreased glucose tolerance, and serum levels of HDL. These MetS-associated changes were found in both FVB/N and C57BL/6 mice that were susceptible or resistant to carcinogen-induced tumorigenesis, respectively, indicating that tumor formation is not involved in the TSC- or NB-mediated MetS. Moreover, oleic acid and palmitoleic acid, which are known to be associated with MetS, were significantly upregulated in the serum of TSC- or NB-treated mice compared with those in vehicle-treated mice. SIGNIFICANCE Both TSC and NB caused detrimental health problems, leading to the development of MetS in experimental mice.

Abstract
Pulmonary emphysema is a destructive inflammatory disease primarily caused by cigarette smoking (CS). Recovery from CS-induced injury requires proper stem cell (SC) activities with a tightly controlled balance of proliferation and differentiation. Here we show that acute alveolar injury induced by two representative tobacco carcinogens, 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone and benzo[a]pyrene (N/B), increased IGF2 expression in alveolar type 2 (AT2) cells to promote their SC function and facilitate alveolar regeneration. Autocrine IGF2 signaling upregulated Wnt genes, particularly Wnt3, to stimulate AT2 proliferation and alveolar barrier regeneration after N/B-induced acute injury. In contrast, repetitive N/B exposure provoked sustained IGF2-Wnt signaling through DNMT3A-mediated epigenetic control of IGF2 expression, causing a proliferation/differentiation imbalance in AT2s and development of emphysema and cancer. Hypermethylation of the IGF2 promoter and overexpression of DNMT3A, IGF2, and the Wnt target gene AXIN2 were seen in the lungs of patients with CS-associated emphysema and cancer. Pharmacologic or genetic approaches targeting IGF2-Wnt signaling or DNMT prevented the development of N/B-induced pulmonary diseases. These findings support dual roles of AT2 cells, which can either stimulate alveolar repair or promote emphysema and cancer depending on IGF2 expression levels. SIGNIFICANCE IGF2-Wnt signaling plays a key role in AT2-mediated alveolar repair after cigarette smoking-induced injury but also drives pathogenesis of pulmonary emphysema and cancer when hyperactivated.

Abstract
The renin-angiotensin (RA) system has been implicated in lung tumorigenesis without detailed mechanistic elucidation. Here, we demonstrate that exposure to the representative tobacco-specific carcinogen nitrosamine 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) promotes lung tumorigenesis through deregulation of the pulmonary RA system. Mechanistically, NNK binding to the nicotinic acetylcholine receptor (nAChR) induces Src-mediated signal transducer and activator of transcription 3 (STAT3) activation, resulting in transcriptional upregulation of angiotensinogen (AGT) and subsequent induction of the angiotensin II (AngII) receptor type 1 (AGTR1) signaling pathway. In parallel, NNK concurrently increases insulin-like growth factor 2 (IGF2) production and activation of IGF-1R/insulin receptor (IR) signaling via a two-step pathway involving transcriptional upregulation of IGF2 through STAT3 activation and enhanced secretion from intracellular storage through AngII/AGTR1/PLC-intervened calcium release. NNK-mediated crosstalk between IGF-1R/IR and AGTR1 signaling promoted tumorigenic activity in lung epithelial and stromal cells. Lung tumorigenesis caused by NNK exposure or alveolar type 2 cell-specific Src activation was suppressed by heterozygous Agt knockout or clinically available inhibitors of the nAChR/Src or AngII/AGTR1 pathways. These results demonstrate that NNK-induced stimulation of the lung RA system leads to IGF2-mediated IGF-1R/IR signaling activation in lung epithelial and stromal cells, resulting in lung tumorigenesis in smokers.

Abstract
The heat shock protein (HSP) system is essential for the conformational stability and function of several proteins. Therefore, the development of efficacious HSP-targeting anticancer agents with minimal toxicity is required. We previously demonstrated that evodiamine is an anticancer agent that targets HSP70 in non-small cell lung cancer (NSCLC) cells. In this study, we synthesized a series of evodiamine derivatives with improved efficacy and limited toxicity. Among the 14 evodiamine derivatives, EV408 (10-hydroxy-14-methyl-8,13,13b,14-tetrahydroindolo [2',3':3,4]pyrido[2,1-b]quinazolin-5(7H)-one) exhibited the most potent inhibitory effects on viability and colony formation under anchorage-dependent and -independent culture conditions in various human NSCLC cells, including those that are chemoresistant, by inducing apoptosis. In addition, EV408 suppressed the cancer stem-like cell (CSC) population of NSCLC cells and the expression of stemness-associated markers. Mechanistically, EV408 inhibited HSP70 function by directly binding and destabilizing the HSP70 protein. Furthermore, EV408 significantly inhibited the growth of NSCLC cell line tumor xenografts without overt toxicity. Additionally, EV408 had a negligible effect on the viability of normal cells. These results suggest the potential of EV408 as an efficacious HSP70-targeting evodiamine derivative with limited toxicity that inhibits both non-CSC and CSC populations in NSCLC.

Abstract
Background Programmed death‐ligand 1 (PD‐L1) has functional roles in cancer stem‐like cell (CSC) phenotypes and chemoresistance besides immune evasion. Chemotherapy is a common treatment choice for colorectal cancer (CRC) patients; however, chemoresistance limits its effectiveness of treatment. Methods We examined the role of S100A14 (SA14) in CRC by adopting PD‐L1high subpopulations within CRC cell lines and patient tumours, by establishing PD‐L1high chemoresistant CRC sublines through prolonged exposure to 5‐fluorouracil/oxaliplatin‐based chemotherapy in vitro and in vivo, and by analysing a public database. Results We identified a novel function of SA14 as a regulator of immune surveillance, major CSC phenotypes, and survival capacity under hostile microenvironments, including those harbouring chemotherapeutics, and as a prognostic biomarker in CRC. Mechanistically, SA14 inhibits PD‐L1 expression by directly interacting with signal transducer and activator of transcription 3 (STAT3) and inducing its proteasome‐mediated degradation. While gain‐of‐SA14 causes loss of PD‐L1 expression and tumourigenic potential and sensitisation to chemotherapy‐induced apoptosis in chemoresistant CRC cells, loss‐of‐SA14 causes increases in PD‐L1 expression, tumourigenic potential, and chemoresistance in vitro and in vivo. We further show that a combinatorial treatment with chemotherapy and recombinant SA14 protein effectively induces apoptosis in PD‐L1high chemoresistant CRC cells. Conclusions Our results suggest that SA14‐based therapy is an effective strategy to prevent tumour progression and that SA14 is a predictive biomarker for anti‐PD‐L1 immunotherapy and chemotherapy in combination.

Abstract
BACKGROUND Cancer stem-like cells (CSCs) play a pivotal role in lung tumor formation and progression. Nerve injury-induced protein 1 (Ninjurin1, Ninj1) has been implicated in lung cancer; however, the pathological role of Ninj1 in the context of lung tumorigenesis remains largely unknown. METHODS The role of Ninj1 in the survival of non-small cell lung cancer (NSCLC) CSCs within microenvironments exhibiting hazardous conditions was assessed by utilizing patient tissues and transgenic mouse models where Ninj1 repression and oncogenic KrasG12D/+ or carcinogen-induced genetic changes were induced in putative pulmonary stem cells (SCs). Additionally, NSCLC cell lines and primary cultures of patient-derived tumors, particularly Ninj1high and Ninj1low subpopulations and those with gain- or loss-of-Ninj1 expression, and also publicly available data were all used to assess the role of Ninj1 in lung tumorigenesis. RESULTS Ninj1 expression is elevated in various human NSCLC cell lines and tumors, and elevated expression of this protein can serve as a biomarker for poor prognosis in patients with NSCLC. Elevated Ninj1 expression in pulmonary SCs with oncogenic changes promotes lung tumor growth in mice. Ninj1high subpopulations within NSCLC cell lines, patient-derived tumors, and NSCLC cells with gain-of-Ninj1 expression exhibited CSC-associated phenotypes and significantly enhanced survival capacities in vitro and in vivo in the presence of various cell death inducers. Mechanistically, Ninj1 forms an assembly with lipoprotein receptor-related protein 6 (LRP6) through its extracellular N-terminal domain and recruits Frizzled2 (FZD2) and various downstream signaling mediators, ultimately resulting in transcriptional upregulation of target genes of the LRP6/β-catenin signaling pathway. CONCLUSIONS Ninj1 may act as a driver of lung tumor formation and progression by protecting NSCLC CSCs from hostile microenvironments through ligand-independent activation of LRP6/β-catenin signaling.

Abstract
Slow-cycling/dormant cancer cells (SCCs) have pivotal roles in driving cancer relapse and drug resistance. A mechanistic explanation for cancer cell dormancy and therapeutic strategies targeting SCCs are necessary to improve patient prognosis, but are limited because of technical challenges to obtaining SCCs. Here, by applying proliferation-sensitive dyes and chemotherapeutics to non-small cell lung cancer (NSCLC) cell lines and patient-derived xenografts, we identified a distinct SCC subpopulation that resembled SCCs in patient tumors. These SCCs displayed major dormancy-like phenotypes and high survival capacity under hostile microenvironments through transcriptional upregulation of regulator of G protein signaling 2 (RGS2). Database analysis revealed RGS2 as a biomarker of retarded proliferation and poor prognosis in NSCLC. We showed that RGS2 caused prolonged translational arrest in SCCs through persistent eukaryotic initiation factor 2 (eIF2α) phosphorylation via proteasome-mediated degradation of activating transcription factor 4 (ATF4). Translational activation through RGS2 antagonism or the use of phosphodiesterase 5 inhibitors, including sildenafil (Viagra), promoted ER stress-induced apoptosis in SCCs in vitro and in vivo under stressed conditions, such as those induced by chemotherapy. Our results suggest that a low-dose chemotherapy and translation-instigating pharmacological intervention in combination is an effective strategy to prevent tumor progression in NSCLC patients after rigorous chemotherapy.

Abstract
Emphysema, a major component of chronic obstructive pulmonary disease (COPD), is a leading cause of human death worldwide. The progressive deterioration of lung function that occurs in the disease is caused by chronic inflammation of the airway and destruction of the lung parenchyma. Despite the main impact of inflammation on the pathogenesis of emphysema, current therapeutic regimens mainly offer symptomatic relief and preservation of lung function with little therapeutic impact. In the present study, we aimed to discover novel therapeutics that suppress the pathogenesis of emphysema. Here, we show that LJ-2698, a novel and highly selective antagonist of the adenosine A3 receptor, a G protein-coupled receptor involved in various inflammatory diseases, significantly reversed the elastase-induced destructive changes in murine lungs. We found that LJ-2698 significantly prevented elastase-induced airspace enlargement, resulting in restoration of pulmonary function without causing any obvious changes in body weight in mice. LJ-2698 was found to inhibit matrix metalloproteinase activity and pulmonary cell apoptosis in the murine lung. LJ-2698 treatment induced increases in anti-inflammatory cytokines in macrophages at doses that displayed no significant cytotoxicity in normal cell lines derived from various organs. Treatment with LJ-2698 significantly increased the number of anti-inflammatory M2 macrophages in the lungs. These results implicate the adenosine A3 receptor in the pathogenesis of emphysema. Our findings also demonstrate the potential of LJ-2698 as a novel therapeutic/preventive agent in suppressing disease development with limited toxicity.

Abstract
Despite the development of advanced therapeutic regimens such as molecular targeted therapy and immunotherapy, the 5-year survival of patients with lung cancer is still less than 20%, suggesting the need to develop additional treatment strategies. The molecular chaperone heat shock protein 90 (Hsp90) plays important roles in the maturation of oncogenic proteins and thus has been considered as an anticancer therapeutic target. Here we show the efficacy and biological mechanism of a Hsp90 inhibitor NCT-50, a novobiocin-deguelin analog hybridizing the pharmacophores of these known Hsp90 inhibitors. NCT-50 exhibited significant inhibitory effects on the viability and colony formation of non-small cell lung cancer (NSCLC) cells and those carrying resistance to chemotherapy. In contrast, NCT-50 showed minimal effects on the viability of normal cells. NCT-50 induced apoptosis in NSCLC cells, inhibited the expression and activity of several Hsp90 clients including hypoxia-inducible factor (HIF)-1α, and suppressed pro-angiogenic effects of NSCLC cells. Further biochemical and in silico studies revealed that NCT-50 downregulated Hsp90 function by interacting with the C-terminal ATP-binding pocket of Hsp90, leading to decrease in the interaction with Hsp90 client proteins. These results suggest the potential of NCT-50 as an anticancer Hsp90 inhibitor.

Abstract
Drug resistance is a major impediment in medical oncology. Recent studies have emphasized the importance of the tumour microenvironment (TME) to innate resistance, to molecularly targeted therapies. In this study, we investigate the role of TME in resistance to cixutumumab, an anti-IGF-1R monoclonal antibody that has shown limited clinical efficacy. We show that treatment with cixutumumab accelerates tumour infiltration of stromal cells and metastatic tumour growth, and decreases overall survival of mice. Cixutumumab treatment stimulates STAT3-dependent transcriptional upregulation of IGF-2 in cancer cells and recruitment of macrophages and fibroblasts via paracrine IGF-2/IGF-2R activation, resulting in the stroma-derived CXCL8 production, and thus angiogenic and metastatic environment. Silencing IGF-2 or STAT3 expression in cancer cells or IGF-2R or CXCL8 expression in stromal cells significantly inhibits the cancer-stroma communication and vascular endothelial cells' angiogenic activities. These findings suggest that blocking the STAT3/IGF-2/IGF-2R intercellular signalling loop may overcome the adverse consequences of anti-IGF-1R monoclonal antibody-based therapies.

Abstract
Abstract
Lung cancer is one of the most commonly diagnosed cancers in the world. Tobacco smoking is the most predominant risk factor for the development of lung cancer. Carcinogenic compounds in tobacco smoke are thought to be responsible for lung cancer, at least in part, by activating G-protein coupled receptor (GPCR)-mediated signaling pathways. GPCR signaling has been suggested to cross-talk with the IGF-1R signaling pathway, a key pathway for cell survival, transformation and growth. However, the mechanisms underlying the crosstalk between GPCR and IGF-1R signaling pathways remain poorly understood. Here we show that tobacco carcinogen (TC) contributes to the lung carcinogenesis by activating the angiotensin signaling and subsequent IGF-1R signaling pathways. We observed that a potent tobacco carcinogen, nitrosamine 4-(methylnitro-samino)-1-(3-pyridyl)-1-butanone (NNK, nicotine-derived nitrosamine ketone), induced transformed phenotypes, including foci formation, viability in the absence of growth factors, and anchorage-dependent and -independent colony formation, and activation of the IGF-1R in normal human bronchial epithelial cells. The NNK treatment also induced lung tumor formation in mice. Losartan, an angiotensin type-1 receptor blocker, and captopril, an angiotensin converting enzyme (ACE) inhibitor, disrupted NNK-induced IGF-1R activation and transformed phenotypes in normal human bronchial epithelial cells and reduced lung tumor formation in mice. These findings indicated that TC-induced angiotensin signaling pathway can enhance lung carcinogenesis by activating the IGF-1R signaling. Our results suggest that targeting IGF-1R by using angiotensin signaling inhibitors may be an effective strategy for the chemoprevention of lung cancer.

Abstract
Abstract
Lung cancer is a leading cause of cancer death worldwide. Although smoking is a main cause, approximately 25% of lung cancer cases are not attributable to tobacco use. Epidemiological studies strongly suggest that chronic stress influences cancer development and progression. Recent mechanistic studies showed that biological signaling pathways could contribute to such effects. But the underlying mechanisms for the association between chronic stress and lung cancer development are poorly understood. The purpose of this study is to investigate whether chronic stress can induce lung cancer development and, if so, what is the mechanism underlying the chronic stress-induced lung cancer development. We observed that stress hormone, norepinephrine (NE) increased cell viability in the absence of growth factors, foci formation, and colony formation in human bronchial epithelial cells and activated the type 1 insulin-like growth factor receptor (IGF-1R) pathway. We found that chronic stress resulted in high levels of NE in serum, activation of IGF-1R in lung tissue and promoted urethane-induced lung tumor formation in vivo. Moreover, inhibition of the IGF-1R pathway suppressed NE-induced transformed phenotypes in vitro. We further confirmed that chronic stress-induced lung tumor formation was greater in mice carrying lung-specific human IGF-1R transgene (Tg) than in wild type mice. Our results indicate that chronic stress may promote lung cancer development via the IGF-1R pathway, suggesting that IGF-1R is an effective target for the chemoprevention of stress-induced lung cancer.

Abstract
Fucoidan, a sulfated polysaccharide, has a variety of biological activities, such as anti-cancer, anti-angiogenic and anti-inflammatory. However, the mechanisms of action of fucoidan as an anti-cancer agent have not been fully elucidated. The present study examined the anti-cancer effect of fucoidan obtained from Undaria pinnatifida in PC-3 cells, human prostate cancer cells. Fucoidan induced the apoptosis of PC-3 cells by activating both intrinsic and extrinsic pathways. The induction of apoptosis was accompanied by the activation of extracellular signal-regulated kinase mitogen-activated protein kinase (ERK1/2 MAPK) and the inactivation of p38 MAPK and phosphatidylinositol 3-kinase (PI3K)/Akt. In addition, fucoidan also induced the up-regulation of p21Cip1/Waf and down-regulation of E2F-1 cell-cycle-related proteins. Furthermore, in the Wnt/β-catenin pathway, fucoidan activated GSK-3β that resulted in the decrease of β-catenin level, followed by the decrease of c-myc and cyclin D1 expressions, target genes of β-catenin in PC-3 cells. These results suggested that fucoidan treatment could induce intrinsic and extrinsic apoptosis pathways via the activation of ERK1/2 MAPK, the inactivation of p38 MAPK and PI3K/Akt signaling pathway, and the down-regulation of Wnt/β-catenin signaling pathway in PC-3 prostate cancer cells. These data support that fucoidan might have potential for the treatment of prostate cancer.

Abstract
Abstract
The type 1 insulin-like growth factor receptor (IGF-1R) signaling is dysregulated in many cancers, thus being a target of cancer therapy. Several preclinical trials have reported the efficacy of IGF-1R targeted therapies, mostly using tyrosine kinase inhibitors or monoclonal antibodies (mAbs); however many of clinical trials have shown limited therapeutic efficacy. In this study, we investigated the resistance mechanism to IGF-1R mAb-based therapies using cixutumumab, a fully humanized mAb against IGF-1R. We tested the efficacy of cixutumumab using OSC19 and 686LN head and neck squamous cell carcinoma (HNSCC) and MDA-MB-231 breast cancer orthotopic and H1299 non-small cell lung cancer (NSCLC) xenograft tumor models. We observed that cixutumumab treatment induced either no change or increased tumor growth and decreased the survival duration of the animals bearing those tumors. Treatment with cixutumumab upregulated migration and invasion of HNSCC and NSCLC cells without any effects on cell proliferation. We further examined the effects of cixutumumab on tumor angiogenesis and found that conditioned media from cancer cells treated with cixutumumab increased tube formation and migration of human umbilical endothelial cells (HUVECs). The angiogenic activity of cixutumumab was also confirmed by matrigel plug assay with HNSCC cell lines. Collectively, these data suggest that cixutumumab-induced angiogenesis-stimulating activities and migration and invasion potential of cancer cells are major factors of resistance to IGF-1R mAbs. These data further suggest that inhibitors of angiogenesis are useful strategy to overcome the resistance against the IGF-1R mAb-based therapy.

Abstract
In this study, we investigated the antitumor effects of deguelin in several human breast cancer cells in vitro and in vivo. Deguelin inhibited cell viability and the anchorage-dependent and anchorage-independent colony formation of triple-negative (MDA-MB-231 and MDA-MB-468) and triple-positive (MCF-7) breast cancer cells, and it significantly reduced the growth of MCF-7 cell xenograft tumors. The induction of apoptosis, inhibition of insulin-like growth factor-1 receptor (IGF-1R) signaling activation, and up-regulation of IGF-binding protein-3 (IGFBP-3) expression may be associated with deguelin-mediated antitumor effects. Our findings suggest a potential therapeutic use for deguelin in patients with triple-negative breast cancer and for those with breast cancers who are sensitive to endocrine- and HER2-targeted therapies.

Abstract
We observed that (1S,2S,3E,7E,11E)-3,7,11,15-Cembratetraen-17,2-olide (LS-1), marine cembrenolide diterpene, inhibited growth and induced apoptosis in colon cancer cells via a reactive oxygen species (ROS) dependent mechanism. Treatment of HT-29 cells with LS-1 resulted in ROS generation, which was accompanied by disruption of mitochondrial membrane potential, cytosolic release of cytochrome c, sub-G1 peak accumulation, activation of Bid, caspase-3, -8, and -9, and cleavage of poly(ADP-ribose) polymerase (PARP) along with the suppressive expression of B cell lymphoma-2 (Bcl-2). All these effects were significantly blocked on pretreatment with the ROS inhibitor N-acetylcysteine (NAC), indicating the involvement of increased ROS in the proapoptotic activity of LS-1. Moreover, we showed that LS-1 induced the phosphorylation of c-Jun N-terminal kinase (JNK) and dephosphorylation of p38, extracellular signal-regulated kinase (ERK), Akt, Src and signal transducer and activator of transcription (STAT)3, which were effectively attenuated by NAC. In addition, the expressions of antioxidant catalase and glutathione peroxidase were abrogated by treatment using LS-1 with or without NAC. These findings reveal the novel anticancer efficacy of LS-1 mediated by the induction of apoptosis via ROS generation in human colon cancer cells.

Abstract
This study was conducted to evaluate the effect of Ecklonia cava, a marine alga native to Jeju Island in Korea, on the promotion of hair growth. When vibrissa follicles were cultured in the presence of E. cava enzymatic extract (which contains more than 35% of dieckol) for 21 days, E. cava enzymatic extract increased hair-fiber length. In addition, after topical application of the 0.5% E. cava enzymatic extract onto the back of C57BL/6 mice, anagen progression of the hair-shaft was induced. The treatment with E. cava enzymatic extract resulted in the proliferation of immortalized vibrissa dermal papilla cells (DPC). Especially, dieckol, among the isolated compounds from the E. cava enzymatic extract, showed activity that increased the proliferation of DPC. When NIH3T3 fibroblasts were treated with the E. cava enzymatic extract and the isolated compounds from the E. cava enzymatic extract, the E. cava enzymatic extract increased the proliferation of NIH3T3 fibroblasts, but the isolated compounds such as eckol, dieckol, phloroglucinol and triphlorethol-A did not affect the proliferation of NIH3T3 fibroblasts. On the other hand, the E. cava enzymatic extract and dieckol significantly inhibited 5α-reductase activity. These results suggest that dieckol from E. cava can stimulate hair growth by the proliferation of DPC and/or the inhibition of 5α-reductase activity.

Abstract
Fucoidan, a sulfated polysaccharide, has various biological activities, such as anticancer, antiangiogenic and antiinflammatory effects; however, the mechanisms of action of fucoidan on anticancer activity have not been fully elucidated. The anticancer effects of fucoidan from Undaria pinnatifida on A549 human lung carcinoma cells were examined. Treatment of A549 cells with fucoidan resulted in potent antiproliferative activity. Also, some typical apoptotic characteristics, such as chromatin condensation and an increase in the population of sub-G1 hypodiploid cells, were observed. With respect to the mechanism underlying the induction of apoptosis, fucoidan reduced Bcl-2 expression, but the expression of Bax was increased in a dose-dependent manner compared with the controls. Furthermore, fucoidan induced caspase-9 activation, but decreased the level of procaspase-3. Cleavage of poly-ADP-ribose polymerase (PARP), a vital substrate of effector caspase, was found. The study further investigated the role of the MAPK and PI3K/Akt pathways with respect to the apoptotic effect of fucoidan, and showed that fucoidan activates ERK1/2 in A549 cells. Unlike ERK1/2, however, treatment with fucoidan resulted in the down-regulation of phospho-p38 expression. In addition, fucoidan resulted in the down-regulation of phospho-PI3K/Akt. Together, these results indicate that fucoidan induces apoptosis of A549 human lung cancer cells through down-regulation of p38, PI3K/Akt, and the activation of the ERK1/2 MAPK pathway.

Abstract
Three new dammarane-type glycosides, named ginsenosides SL(1)-SL(3) (1-3), and eleven known compounds (4-14) were isolated from the heat-processed leaves of Panax ginseng. Their structures were elucidated on the basis of extensive chemical and spectroscopic methods. Cytotoxic-activity testing of compounds 1-14 against human leukemia HL-60 cells showed that ginsenosides Rh(3) (11) and Rk(2) (12) exhibited potent effects with IC(50) values of 0.8 and 0.9 microM. In addition, ginsenosides SL(3) (3), 20S-Rg(2) (7), F(4) (10), 20S-Rh(2) (13) displayed strong activity with IC(50) values of 9.0, 9.0, 7.5, and 8.2 microM, respectively. This is the first report on chemical components of the steamed ginseng leaves.

Abstract
Recently, it was reported that in a 4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) model, neuronal cell death is associated with the cdk5-mediated hyperphosphorylation of myocyte enhancer factor 2 (MEF2), a transcription factor that is critically required for neuronal survival. In the present study, we investigated the possible involvement of cdk5-mediated MEF2D down-regulation on 6-hydroxydopamine (6-OHDA)-induced PC12 cell death. 6-OHDA was found to significantly increase nitric oxide (NO) production and to induce apoptosis in a time-dependent manner in PC12 cells. Furthermore, 6-OHDA was found to markedly reduce MEF2D levels under conditions that could induce PC12 cell apoptosis. In addition, PC12 cell death and MEF2D degradation by 6-OHDA were prevented by the cdk5 inhibitor roscovitine, but roscovitine could not restore the 6-OHDA-induced inactivation of Akt. These results suggest that the cell death and MEF2D degradation caused by 6-OHDA are dependent on cdk5 activity. On the other hand, roscovitine enhanced the 6-OHDA-induced activations of ERK1/2 and JNK, but reduced the 6-OHDA-induced activation of p38. These results suggest that PC12 cell death by 6-OHDA appears to be regulated by the down-regulation of MEF2D via some interaction between cdk5 and MAP kinase.

One newly (1) and 10 known oleanane-type triterpenoids (2-11) were isolated from the methanol extract of Panax stipuleanatus rhizomes. Based on their spectroscopic data, these compounds were identified as spinasaponin A methyl ester (1), pesudoginsenoside RP(1) methyl ester (2), spinasaponin A 28-O-glucoside (3), pseudoginsenoside RT(1) methyl ester (4), pseudoginsenoside RT(1) (5), stipuleanoside R(2) methyl ester (6), stipuleanoside R(2) (7), araloside A methyl ester (8), 3-O-β-D-glucopyranosyl (1→3)-β-D-glucuronopyranoside-28-O-β-D-glucopyranosyl oleanolic acid methyl ester (9), 3-O-β-D-xylopyranosyl (1→2)-β-D-glucopyranosyl-28-O-β-D-glucopyranosyl oleanolic acid (10), and chikusetsusaponin IVa (11). When the cytotoxic activities of the isolated compounds were evaluated, compound 1 exhibited significant cytotoxic activity with IC(50) values of 4.44 and 0.63 μM against HL-60 (leukemia) and HCT-116 (colon cancer) cell lines, respectively. Compound 2 showed potent cytotoxicity with an IC(50) of 6.50 μM against HCT-116, whereas it was less cytotoxic against HL-60 (IC(50)=41.45 μM). After HL-60 and HCT-116 were treated with compounds 1 and 2, increased production of apoptotic bodies was observed. Furthermore, compounds 1 and 2 in HCT-116 cells activated intrinsic and extrinsic apoptosis pathways by upregulating DR-5 and Bax, downregulating Bcl-2, activating caspase-9, and cleaving poly-ADP-ribose polymerase (PARP). We also observed the activation of ERK1/2 MAPK by both compounds in the HCT-116 cells. Together, compounds 1 and 2 might induce intrinsic and extrinsic apoptosis pathways through the activation of the ERK1/2 MAPK pathway in HCT-116 colon cancer cells. Structure-activity relationship analysis indicated that a carboxyl group at position-28 is potentially responsible for the cytotoxic effects.

Abstract
The antitumor activity of fucoidan from Fucus vesiculosus was investigated in human colon carcinoma cells. The crude fucoidan, a polysaccharide composed predominantly of sulfated fucose, markedly inhibited the growth of HCT-15 cells (human colon carcinoma cells). After HCT-15 cells were treated with fucoidan, several apoptotic events such as DNA fragmentation, chromatin condensation and increase of the population of sub-G1 hypodiploid cells were observed. In the mechanism of fucoidan-induced apoptosis, we examined changes in Bcl-2 and Bax protein expression levels and activation of caspases. Fucoidan decreased Bcl-2 expression, whereas the expression of Bax was increased in a time-dependent manner compared to the control. In addition, the active forms of caspase-9 and caspase-3 were increased, and the cleavage of poly(ADP-ribose) polymerase (PARP), a vital substrate of effector caspase, was observed. Furthermore, the induction of apoptosis was also accompanied by a strong activation of extracellular signal-regulated kinase (ERK) and p38 kinase and an inactivation of phosphatidylinositol 3-kinase (PI3K)/Akt in a time-dependent manner. These findings provide evidence demonstrating that the pro-apoptotic effect of fucoidan is mediated through the activation of ERK, p38 and the blocking of the PI3K/Akt signal pathway in HCT-15 cells. These data support the hypothesis that fucoidan may have potential in colon cancer treatment.
