Abstract
Anoikis plays an important role in cancer invasion and metastasis. However, the role of anoikis-related genes, AnRGs, in lung adenocarcinoma (LUAD) is not clear. First, anoikis-related genes (AnRGs) were obtained from the Genecard database. Second, the prognostic risk model of AnRGs was established by univariate Cox analysis, the Least Absolute Shrinkage and Selection Operator (LASSO) analysis, and multivariate Cox analysis. Finally, in vitro cell experiments were carried out to determine the expression and function of the key gene AnRGs. Three AnRGs (angiopoietin-like 4, ANGPTL4; Cyclin-Dependent Kinase Inhibitor 3, CDKN3; Solute Carrier Organic Anion Transporter Family Member 1B3, SLCO1B3) were screened for the construction of risk prediction model. Additionally, ANGPTL4 was significantly highly expressed in tumor cells, and the knockdown of ANGPTL4 expression on tumor cells could inhibit tumor cell migration and apoptosis. Constructing a risk model based on anoikis-related genes can effectively differentiate the prognosis of LUAD. ANGPTL4 can be used as a potential new target for LUAD treatment.

Abstract
Within the tumor microenvironment, the fight between the immune system and cancer influences tumor transformation. Metastasis formation is an important stage in the progression of cancer. This process is aided by cellular detachment and resistance to anoikis, which are achieved by altering intercellular signaling. Autophagy, specifically pro-survival autophagy, aids cancer cells in developing treatment resistance. Numerous studies have shown that autophagy promotes tumor growth and resistance to anoikis. To regulate protective autophagy, cancer-related genes phosphorylate both pro- and anti-apoptotic proteins. Apoptosis, a type of controlled cell death, eliminates damaged or unwanted cells. Anoikis is a type of programmed cell death in which cells lose contact with the extracellular matrix. The dysregulation of these cellular pathways promotes tumor growth and spread. Apoptosis, anoikis, and autophagy interact meticulously and differently depending on the cellular circumstances. For instance, autophagy can protect cancer cells from apoptosis by removing cellular components that are damaged and might otherwise trigger apoptotic pathways. Similarly, anoikis dysregulation can trigger autophagy by causing cellular harm and metabolic stress. In order to prevent or treat metastatic disease, specifically, targeting these cellular mechanisms may present a promising prospect for cancer therapy. This review discourses the state of our understanding of the molecular and cellular mechanisms underlying tumor transformation and the establishment of metastatic tumors. To enhance the prognosis for cancer, we highlight and discuss potential therapeutic approaches that target these processes and genes involved in them.

Abstract
Exosomes are nanoscale (40-100 nm) vesicles secreted by different types of cells and have attracted extensive interest in recent years because of their unique role in disease development. It can carry related goods, such as lipids, proteins, and nucleic acids, to mediate intercellular communication. This review summarizes exosome biogenesis, release, uptake, and their role in mediating the development of liver diseases and cancer, such as viral hepatitis, drug-induced liver injury, alcohol-related liver disease, non-alcoholic fatty liver disease, hepatocellular carcinoma, and other tumors. Meanwhile, a fossa structural protein, caveolin-1(CAV-1), has also been proposed to be involved in the development of various diseases, especially liver diseases and tumors. In this review, we discuss the role of CAV-1 in liver diseases and different tumor stages (inhibition of early growth and promotion of late metastasis) and the underlying mechanisms by which CAV-1 regulates the process. In addition, CAV-1 has also been found to be a secreted protein that can be released directly through the exosome pathway or change the cargo composition of the exosomes, thus contributing to enhancing the metastasis and invasion of cancer cells during the late stage of tumor development. In conclusion, the role of CAV-1 and exosomes in disease development and the association between them remains to be one challenging uncharted area.

Abstract
Simple Summary Anoikis is a programmed cell death process resulting from the loss of interaction between cells and the extracellular matrix. Therefore, it is necessary to overcome anoikis when tumor cells acquire metastatic potential. In lung cancer, the composition of the extracellular matrix, cell adhesion-related membrane proteins, cytoskeletal regulators, and epithelial–mesenchymal transition are involved in the process of anoikis, and the initiation of apoptosis signals is a critical step in anoikis. Inversely, activation of growth signals counteracts anoikis. This review summarizes the regulators of lung cancer-related anoikis and explores potential drug applications targeting anoikis. Abstract Tumor metastasis occurs in lung cancer, resulting in tumor progression and therapy failure. Anoikis is a mechanism of apoptosis that combats tumor metastasis; it inhibits the escape of tumor cells from the native extracellular matrix to other organs. Deciphering the regulators and mechanisms of anoikis in cancer metastasis is urgently needed to treat lung cancer. Several natural and synthetic products exhibit the pro-anoikis potential in lung cancer cells and in vivo models. These products include artonin E, imperatorin, oroxylin A, lupalbigenin, sulforaphane, renieramycin M, avicequinone B, and carbenoxolone. This review summarizes the current understanding of the molecular mechanisms of anoikis regulation and relevant regulators involved in lung cancer metastasis and discusses the therapeutic potential of targeting anoikis in the treatment of lung cancer metastasis.

Abstract
Non-small cell lung cancer (NSCLC) is one of the most frequent cancers worldwide, yet effective treatment remains a clinical challenge. Guaiazulene (GYZ), a cosmetic color additive, has previously been characterized as a potential antitumor agent due to observed anticancer effects. However, the efficacy of GYZ in the treatment of NSCLC and the involved molecular mechanisms remain largely unknown. Here, we indicated a role for GYZ in the suppression of NSCLC both in vitro and in vivo via triggering reactive oxygen species (ROS)-induced apoptosis. Concomitantly, GYZ induced complete autophagic flux in NSCLC cells via inhibiting the Akt/mTOR signaling pathway, which displayed cytoprotective effect against GYZ-induced growth suppression. Accompanied with autophagy inhibition obviously enhanced the effects of GYZ. Notably, GYZ acts synergistically with paclitaxel in the suppression of NSCLC in vitro. Together, our results for the first time reported that GYZ suppressed the proliferation of NSCLC and suggested a potential strategy for inhibiting NSCLC growth by combinational use of GYZ and autophagy inhibitors.

Abstract
Cancer is a global health concern, and the prognosis of patients with cancer is associated with metastasis. Multistep processes are involved in cancer metastasis. Accumulating evidence has shown that cancer cells acquire the capacity of anoikis resistance and anchorage-independent cell growth, which are critical prerequisite features of metastatic cancer cells. Multiple cellular factors and events, such as apoptosis, survival factors, cell cycle, EMT, stemness, autophagy, and integrins influence the anoikis resistance and anchorage-independent cell growth in cancer. Noncoding RNAs (ncRNAs), such as microRNAs (miRNAs) and long noncoding RNAs (lncRNAs), are dysregulated in cancer. They regulate cellular signaling pathways and events, eventually contributing to cancer aggressiveness. This review presents the role of miRNAs and lncRNAs in modulating anoikis resistance and anchorage-independent cell growth. We also discuss the feasibility of ncRNA-based therapy and the natural features of ncRNAs that need to be contemplated for more beneficial therapeutic strategies against cancer.

Abstract
Lung cancer is one of the most common and malignant cancers with extremely high morbidity and mortality in both males and females. Although traditional lung cancer treatments are fast progressing, there are still limitations. Caveolin-1 (Cav-1), a main component of caveolae, participates in multiple cellular events such as immune responses, endocytosis, membrane trafficking, cellular signaling and cancer progression. It has been found tightly associated with lung cancer cell proliferation, migration, apoptosis resistance and drug resistance. In addition to this, multiple bioactive molecules have been confirmed to target Cav-1 to carry on their anti-tumor functions in lung cancers. Cav-1 can also be a predictor for lung cancer patients’ prognosis. In this review, we have summarized the valuable research on Cav-1 and lung cancer in recent years and discussed the multifaceted roles of Cav-1 on lung cancer occurrence, development and therapy, hoping to provide new insights into lung cancer treatment.

Abstract
Emerging evidence suggests that extracellular vesicle (EV)-containing miRNAs mediate intercellular communications in response to noxious stimuli. It remains unclear how a cell selectively sorts the cellular miRNAs into EVs. We report that caveolin-1 (cav-1) is essential for sorting of selected miRNAs into microvesicles (MVs), a main type of EVs generated by outward budding of the plasma membrane. We found that cav-1 tyrosine 14 (Y14)-phosphorylation leads to interactions between cav-1 and hnRNPA2B1, an RNA-binding protein. The cav-1/hnRNPA2B1 complex subsequently traffics together into MVs. Oxidative stress induces O-GlcNAcylation of hnRNPA2B1, resulting in a robustly altered hnRNPA2B1-bound miRNA repertoire. Notably, cav-1 pY14 also promotes hnRNPA2B1 O-GlcNAcylation. Functionally, macrophages serve as the principal recipient of epithelial MVs in the lung. MV-containing cav-1/hnRNPA2B1 complex-bound miR-17/93 activate tissue macrophages. Collectively, cav-1 is the first identified membranous protein that directly guides RNA-binding protein into EVs. Our work delineates a novel mechanism by which oxidative stress compels epithelial cells to package and secrete specific miRNAs and elicits an innate immune response.

Abstract
Metastasis is a key driving force behind the high mortality rate associated with lung cancer. Herein, we report the first study revealing the antimetastasis activity of jorunnamycin A, a bistetrahydroisoquinolinequinone isolated from a Thai blue sponge Xestospongia sp. evidenced by its inhibition of epithelial to mesenchymal transition (EMT), sensitization of anoikis, and suppression of anchorage-independent survival in human lung cancer cells. Treatment with jorunnamycin A (0.05-0.5 μM) altered the expression of p53 and Bcl-2 family proteins, particularly causing the down-regulation of antiapoptosis Bcl-2 and Mcl-1 proteins. Under detachment conditions for 12 h, jorunnamycin A-treated cells exhibited diminution of pro-survival proteins p-Akt and p-Erk as well as the survival-promoting factor caveolin-1. Corresponding with the inhibition on the Akt and Erk pathway as well as activation of p53, there was an increase in the epithelial marker E-cadherin and a remarkable decrease of EMT markers and associated proteins including vimentin, snail, and claudin-1. As the loss of anchorage dependence is an important barrier to metastasis, the observed inhibitory effects of jorunnamycin A on the coordinating networks of EMT and anchorage-independent growth emphasize the potential development of jorunnamycin A as an effective agent against lung cancer metastasis.

Abstract
BACKGROUND A Lung cancer death account for approximately 1 in 5 of all cancer-related deaths and is particularly virulent due to its enhanced metastasis and resistance to chemotherapy. Chrysotobibenzyl has been reported to decrease cell metastasis, according to the results of an anchorage-independent growth assay; however, its underlying mechanism has not been investigated yet. PURPOSE The aim of this study was to investigate the effect of chrysotobibenzyl on lung cancer cell migration and drug sensitization and its mechanism. METHODS Cell viability, cell proliferation and drug sensitization were determined by MTT assay. Cell migration was analyzed using a wound-healing assay. Transwell migration and invasion were analyzed using Boyden chamber assay. Mechanisms of chrysotobibenzyl against metastasis including cell migration, invasion, and epithelial to mesenchymal transition (EMT) were evaluated by Western blot analysis and immunofluorescence. RESULTS Treatment with chrysotobibenzyl was applied at concentrations of 0-50 µM and the results showed non-cytotoxicity in human lung cancer cells (H460, H292, A549, and H23) and other non-cancerous human cells (HCT116, primary DP1 and primary DP2). However, 50 µM of chrysotobibenzyl significantly altered cell proliferation in H292 cells at 48 h. In addition, 1-50 µM of chrysotobibenzyl significantly inhibited H460 and H292 cell migration, invasion, filopodia formation, and decreased EMT in a dose-dependent manner at 48 h, which were correlated with reduced protein levels of integrins β1, β3, and αν, p-FAK, p-AKT, Cdc42, and Cav-1. We also established shRNA-Cav-1-transfected (shCav-1) H460 and H292 cells. shCav-1 transfected cells can decrease cell migration and downregulate the expression of integrins β1, β3, and αν when compared with the control. Moreover, chrysotobibenzyl was shown to suppress EMT indicated by the reduction of EMT markers (Vimentin, Snail, and Slug), and sensitize lung cancer cells to cisplatin-mediated apoptosis. CONCLUSION Treatment with chrysotobibenzyl inhibited lung cancer cell migration via Cav-1, integrins β1, β3, and αν, and EMT suppressions. The downregulation of integrins in response to the compound not only inhibited cell metastasis, but also sensitized lung cancer cells to cisplatin-mediated apoptosis.

Abstract
Regulation of both the extrinsic and the mitochondria-dependent intrinsic apoptotic pathways plays a key role in the development of the hematopoietic system, for sustaining cell survival during generation of various cell types, in eliminating cells with dual identities such as CD4/CD8 double-positive cells (Hettmann, Didonato, Karin, & Leiden, 1999; Ogasawara, Suda, & Nagata, 1995), for sustaining cells during the rapid clonal expansion phase (Schirmer, Vallejo, Weyand, & Gronzy, 1998), as well as eliminating cells during the contraction phase (Yajima et al., 2006). The anti-apoptotic protein Mcl-1 is necessary for sustaining hematopoietic stem cells (HPS) (Akashi et al., 2003; Akashi, Traver, Miyamoto, & Weissman, 2000). The anti-apoptotic factors Mcl-1, Bcl-2, and Bcl-xL were also found to be over-expressed in acute myeloid leukemia (AML) (Kaufmann et al., 2016) and acute lymphocytic leukemia (ALL) (Findley, Gu, Yeager, & Zhou, 1997), suggesting that dis-regulated apoptotic processes could be a factor in the instigation of leukemia and/or its relapse. Molecules targeting these proteins were used as single agents to treat leukemia. However, by using a set of recently developed specific molecule inhibitors targeting anti-apoptotic proteins, distinct roles are being discovered for these anti-apoptotic proteins during hematopoietic and tumor development. Furthermore, using these inhibitors in proper combinations can effectively induce apoptosis in various solid tumors, even though each agent on its own cannot induce apoptosis in them. These new findings suggest that inhibiting anti-apoptotic elements can induce apoptosis without external stimuli in most cells, but it comes with a risk that some combinations could also trigger apoptosis in healthy cells. One way to address the safety issue is by limiting exposure to all the agents to only cancer cells, thus making the combination safe and effective. In this article, we review this rapidly developing idea in cancer research.

Abstract
Circulating tumor cells (CTCs) need to acquire resistance to anoikis to survive after they experience fluid shear stress in the circulatory and lymphatic systems. However, the mechanism by which tumor cells resist anoikis under shear stress conditions remains unknown. Here, we found that the application of low shear stress (LSS; 2 dyn/cm2 ) to human breast carcinoma cells (MDA-MB-231) resulted in increased anoikis resistance when tumor cells were grown under anchorage-independent conditions. Caveolin-1 (Cav-1), the major component of plasma membrane caveolae, was overexpressed in LSS-treated cells and prevented tumor cells from anoikis, while depletion of Cav-1 restored sensitivity to anoikis. LSS-induced dissociation of Cav-1-Fas inhibited formation of the death-inducing signaling complex, caspase-8 activation, and rendered tumor cells resistant to anoikis. Likewise, LSS blocked the mitochondrial pathway through promotion of integrin β1-focal adhesion kinase-mediated multicellular aggregation and suppression of truncated BID translocation mediated crosstalk between the extrinsic and intrinsic apoptotic pathways. Our findings provide insights into the mechanisms by which LSS induces anoikis resistance in breast carcinoma cells through inhibition of Cav-1-dependent extrinsic and intrinsic apoptotic pathways, and serves as a potential therapeutic target for CTCs and metastatic breast cancer.

Abstract
Anoikis resistance is considered to be an essential prerequisite of tumor metastasis and which is an important mechanism in the metastatic process of gastric cancer (GC). Caveolin-1 (CAV-1), a protein component of caveolae, has been reported to regulate several cancer cell behaviors including anoikis resistance. However, the role of CAV-1 in the acquisition of anoikis resistance in GC cells has never been explored. In this study, we investigated the promoting effect of CAV-1 on anchorage-independent growth and anoikis resistance, and the involvement of the related signaling pathways in such process in SGC-7901 cells. The results showed that CAV-1 could promote anchorage-independent growth and anoikis resistance in detached SGC-7901 cells, which was associated with the activation of Src-dependent epidermal growth factor receptor-integrin β signaling as well as the phosphorylation of PI3K/Akt and MEK/ERK signaling pathways. The data from this study might contribute to the in-depth understanding of the metastatic mechanism for GC.

Abstract
BACKGROUND During metastasis, cancer cells require anokis resistant mechanism to survive until reach the distant secondary tissues. As anoikis sensitization may benefit for cancer therapy, this study demonstrated the potential of avicequinone B, a natural furanonaphthoquinone found in mangrove tree (Avicenniaceae) to sensitize anoikis in human lung cancer cells. METHODS Anoikis inducing effect was investigated in human lung cancer H460, H292 and H23 cells that were cultured in ultra-low attachment plate with non-cytotoxic concentrations of avicequinone B. Viability of detached cells was evaluated by XTT assay at 0-24 h of incubation time. Soft agar assay was performed to investigate the inhibitory effect of avicequinone B on anchorage-independent growth. The alteration of anoikis regulating molecules including survival and apoptosis proteins were elucidated by western blot analysis. RESULTS Avicequinone B at 4 μM significantly induced anoikis and inhibited proliferation under detachment condition in various human lung cancer cells. The reduction of anti-apoptotic proteins including anti-apoptotic protein B-cell lymphoma 2 (Bcl-2) and myeloid cell leukemia 1 (Mcl-1) associating with the diminution of integrin/focal adhesion kinase (FAK)/Proto-oncogene tyrosine-protein kinase (Src) signals were detected in avicequinone B-treated cells. CONCLUSIONS Avicequinone B sensitized anoikis in human lung cancer cells through down-regulation of anti-apoptosis proteins and integrin-mediated survival signaling.

Abstract
A single cancer cell left behind after surgery and/or chemotherapy could cause a recurrence of cancer. It is our belief that the failure of chemotherapies is the failure to induce apoptosis in all cancer cells. Given the extraordinary heterogeneity of cancer, it is very difficult to eliminate all cancer cells with a single agent targeting a particular gene product. Furthermore, combinations of any two or three agents exhibiting some proven efficacy on a particular cancer type have not fared better, often compounding adverse effects without evidence of expected synergistic effects. Thus, it is imperative that a way be found to select candidates that when combined, will (1) synergize, making the combination therapy greater than the sum of its parts, and (2) target all the cancer cells in a patient. In this article, we discuss our experience and relation to current evidence in the cancer treatment literature in which, by deconstructing signaling networks, we have identified a lynchpin that connects the growth signals present in cancer with mitochondria-dependent apoptotic pathways. By targeting this lynchpin, we have added a key component to a combination therapy that sensitizes cancer cells for apoptosis.

Abstract
Cancer stem cells (CSCs), a subpopulation of cancer cells with high aggressive behaviors, have been identified in many types of cancer including lung cancer as one of the key mediators driving cancer progression and metastasis. Here, we have reported for the first time that ciprofloxacin (CIP), a widely used anti-microbial drug, has a potentiating effect on CSC-like features in human non-small cell lung cancer (NSCLC) cells. CIP treatment promoted CSC-like phenotypes, including enhanced anchorage-independent growth and spheroid formation. The known lung CSC markers: CD133, CD44, ABCG2 and ALDH1A1 were found to be significantly increased, while the factors involving in epithelial to mesenchymal transition (EMT): Slug and Snail, were depleted. Also, self-renewal transcription factors Oct-4 and Nanog were found to be up-regulated in CIP-treated cells. The treatment of CIP on CSC-rich populations obtained from secondary spheroids resulted in the further increase of CSC markers. In addition, we have proven that the mechanistic insight of the CIP induced stemness is through Caveolin-1 (Cav-1)-dependent mechanism. The specific suppression of Cav-1 by stably transfected Cav-1 shRNA plasmid dramatically reduced the effect of CIP on CSC markers as well as the CIP-induced spheroid formation ability. Cav-1 was shown to activate protein kinase B (Akt) and extracellular signal-regulated kinase (ERK) pathways in CSC-rich population; however, such an effect was rarely found in the main lung cancer cells population. These findings reveal a novel effect of CIP in positively regulating CSCs in lung cancer cells via the activation of Cav-1, Akt and ERK, and may provoke the awareness of appropriate therapeutic strategy in cancer patients.

Abstract
Metastasis in lung cancer has been recognized as an important cause of high mortality. Resistance to anoikis and the epithelial-to-mesenchymal transition (EMT) are critical factors for the successful spread of cancer cells. Compounds that suppress these features of cancer cells should be potentially active for anti-metastasis approaches. We have demonstrated for the first time that moscatilin, at its non-toxic concentrations to lung cancer cells and human normal keratinocytes, significantly decreases lung cancer cell survival in the detached condition, and suppresses the formation of tumors in an anchorage-independent growth assay. Furthermore, we found that moscatilin significantly decreased the activated level of survival proteins, namely ERK and Akt. In addition, moscatilin down-regulated cavelolin-1 (Cav-1), leading to a reduction in anti-apoptotic Mcl-1 protein. In terms of EMT, treatment of the cells with moscatilin significantly suppressed mesenchymal cell markers, namely vimentin, Slug, and Snail. These results indicate that moscatilin inhibited anoikis resistance in lung cancer cells via survival suppression, Cav-1 down-regulation, and inhibition of EMT. The compound could therefore be beneficial for the treatment and prevention of lung cancer metastasis.

Abstract
Caveolins have recently attracted attention for their possible involvement in signal transduction. Their role in cancer is debated, being reported both a suppressive and oncogenic role in different experimental conditions. Caveolin-1 is regulated by the tumor suppressor p53 which is able to bind its promoter and activate transcription. We had previous evidences indicating that a specific p73 isoform, namely ∆Np73β, when overexpressed in NCI-H1299 induced growth arrest and cell death. By gene expression analysis in cell transiently overexpressed with ∆Np73β, a strong induction of caveolin-1 was found. Caveolin was induced both at mRNA and protein level, and we characterised the promoter sequence of the gene encoding for caveolin-1 and found that the promoter region containing the putative p53 (and hence p73) binding sequence was responsive to ∆Np73β, but not to ∆Np73α and ∆Np73γ which do not induce growth arrest as ∆Np73β does. A reduction in cell adhesion was observed in ∆Np73β overexpressing cells, again supporting a possible role of caveolins in determining these effects. By using specific siRNA directed against human caveolin-1, we could not however antagonize the effects induced by ∆Np73β. Although caveolin-1 represents one of the genes whose expression is strongly activated by ∆Np73β, we could not define a role of caveolin-1 as a mediator of ∆Np73β associated growth arrest. It could well be that the expression of caveolin-1 is able to mediate other activities of ∆Np73β, and studies are in progress to determine whether its expression is mainly associated to metastatic spread.

Abstract
Sufficient knowledge regarding cellular and molecular basis of lung cancer progression and metastasis would help in the development of novel and effective strategies for the treatment of lung cancer. 4HPR is a synthetic retinoid with potential anti-tumor activity but is still limited because of its poor bioavailability. The use of albumin as a complexing agent for a hydrophobic drug is expected to improve the water solubility and consequently their bioavailability.This study investigated the antitumor activity of a novel complex between albumin and 4-HPR in a mouse model of human lung cancer and focuses on role and mechanism of Cav-1 mainly involved in regulating cancer and Acsvl3 mainly connected with tumor growth. Their expressions were assayed by immunohistochemistry and qRT-PCR, to demonstrate the reduction of the tumor growth following the drug treatment. Our results showed a high antitumor activity of 4HPR-HSA by reduction of the volume of tumor mass and the presence of a high level of apoptotic cell by TUNEL assay. The downregulation of Cav-1 and Acsvl3 suggested a reduction of tumor growth. In conclusion, we demonstrated the great potential of 4HPR-HSA in the treatment of lung cancer. More data about the mechanism of drug delivery the 4HPR-HSA are necessary.

Abstract
Even though tremendous advances have been made in the treatment of cancers during the past decades, the success rate among patients with cancer is still dismal, largely because of problems associated with chemo/radioresistance and relapse. Emerging evidence has indicated that cancer stem cells (CSCs) are behind the resistance and recurrence problems, but our understanding of their regulation is limited. Rapid reversible changes of CSC-like cells within tumors may result from the effect of biological mediators found in the tumor microenvironment. Here we show how nitric oxide (NO), a key cellular modulator whose level is elevated in many tumors, affects CSC-like phenotypes of human non-small cell lung carcinoma H292 and H460 cells. Exposure of NO gradually altered the cell morphology toward mesenchymal stem-like shape. NO exposure promoted CSC-like phenotype, indicated by increased expression of known CSC markers, CD133 and ALDH1A1, in the exposed cells. These effects of NO on stemness were reversible after cessation of the NO treatment for 7 days. Furthermore, such effect was reproducible using another NO donor, S-nitroso-N-acetylpenicillamine. Importantly, inhibition of NO by the known NO scavenger 2-(4-carboxy-phenyl)-4,4,5,5 tetramethylimidazoline-1-oxy-3-oxide strongly inhibited CSC-like aggressive cellular behavior and marker expression. Last, we unveiled the underlying mechanism of NO action through the activation of caveolin-1 (Cav-1), which is upregulated by NO and is responsible for the aggressive behavior of the cells, including anoikis resistance, anchorage-independent cell growth, and increased cell migration and invasion. These findings indicate a novel role of NO in CSC regulation and its importance in aggressive cancer behaviors through Cav-1 upregulation.

Dendrofalconerol A sensitizes anoikis and inhibits migration in lung cancer cells. J Nat Med 2014; 69:178-90.

Abstract
Resistance to anoikis, enhanced cell motility, and growth in anchorage-independent conditions are hallmarks of highly metastatic cancer cells. The present study demonstrates the anoikis-sensitizing and anti-migration activities of dendrofalconerol A (DF-A), a pure bis(bibenzyl) isolated from the stem of Dendrobium falconeri (Orchidaceae), and its underlying mechanisms in human lung cancer H460 cells. DF-A at non-toxic concentrations significantly increased the anoikis response of the cancer cells, but caused no toxic effect on normal keratinocytes. In addition, DF-A significantly inhibited the growth of lung cancer cells in anchorage-independent conditions. Western blot analysis revealed that the anoikis-sensitizing effect of such a compound involves its ability to suppress survival signals as well as anti-apoptotic proteins, namely, activated protein kinase B (Akt) and Bcl-2. Furthermore, DF-A decreased caveolin-1 (Cav-1), a protein responsible for aggressiveness, while having no effect on Bax, Mcl-1, and activated Erk (p42/44) proteins. In the case of cell motility, DF-A exhibited strong anti-migration activity with the mechanism involving suppression of pFAK and Rho-GTP, but had no effect on Rac-GTP in lung cancer cells. Taken together, DF-A possesses anoikis-sensitizing activity along with anti-migration effects, and may be developed as a novel active compound for cancer treatment.

Prolonged nitric oxide exposure enhances anoikis resistance and migration through epithelial-mesenchymal transition and caveolin-1 upregulation. BIOMED RESEARCH INTERNATIONAL 2014; 2014:941359. [PMID: 24967418 PMCID: PMC4055163 DOI: 10.1155/2014/941359] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/03/2014] [Accepted: 05/01/2014] [Indexed: 11/18/2022]
Abstract
Nitric oxide (NO) in tumor microenvironment may have a significant impact on metastatic behaviors of cancer. Noncytotoxic doses of NO enhanced anoikis resistance and migration in lung cancer H23 cells via an increase in lamellipodia, epithelial-mesenchymal transition (EMT) markers including vimentin and snail, and caveolin-1 (Cav-1). However, the induction of EMT was found in Cav-1-knock down cells treated with NO, suggesting that EMT was through Cav-1-independent pathway. These effects of NO were consistently observed in other lung cancer cells including H292 and H460 cells. These findings highlight the novel role of NO on EMT and metastatic behaviors of cancer cells.

Abstract
Cancer cell aggregation has been long known to facilitate metastatic potential of cancer cells. In addition, the presence of nitric oxide (NO) in cancer area may have a significant impact on aggregation behavior of the cells. We show herein that lung cancer H460 cells possessing high ability of anoikis resistance formed loose aggregates in detached condition. Importantly, NO treatment tightened the aggregates by enhancing cell-cell interaction via E-cadherin-dependent mechanism, and such E-cadherin contact increased anoikis resistance potential by up-regulating pro-survival signals of the cells including active ATP-dependent tyrosine kinase and extracellular-regulated protein kinases (ERK1/2). Since an increase of E-cadherin was frequently found in mesenchymal to epithelial transition (MET) process, we further tested the cells for MET markers and found that NO treatment of these cells significantly enhanced MET. As aggregation and MET of cancer cells may facilitate cancer metastasis by many means, the insights gained from the present study could benefit the deep understanding in the biology of cancer cell metastasis.

Abstract
Transforming growth factor activated kinase 1 (TAK1) provides prosurvival signals in various types of cells, and emerging evidence indicates that targeting TAK1 is a promising means to eliminate certain types of cancer cells. Here, we show that TAK1 is required for efficient tumorigenicity of AKT-transformed cells. TAK1 inhibition accelerates cell apoptosis of AKT-transformed cells in anchorage-independent cell growth accompanying by the downregulation of Mcl-1 and Bcl-2 expression. On the contrary, the tumorigenicity of c-Myc-transformed cells is not significantly affected by TAK1 inhibition. Moreover, AKT-transformed cells with c-Myc overexpression tolerate TAK1 inhibition in anchorage-independent growth and tumorigenicity in vivo. Together, our results provide evidence that TAK1-dependency in the tumorigenicity of AKT-transformed cells can be alleviated by c-Myc overexpression. These findings suggest that dual-targeting TAK1 and c-Myc might be a rational therapeutic strategy for treatment of certain types of cancer.

Abstract
PURPOSE Anoikis ('homelessness' in Greek) is a form of apoptosis following the detachment of cells from the appropriate extracellular matrix (Chiarugi and Giannoni in Biochem Pharmacol 76:1352-1364, 2008). Resistance to anoikis is a critical mediator of metastasis in cancer by enabling cancer cells to survive during invasion and transport in the blood and lymph. Numerous regulators and mechanisms of anoikis in human cancer have been proposed to date. Consequently, the identification of key regulators of anoikis that can be targeted to at least partially restore anoikis sensitivity in cancer cells is important in the development of therapies to treat metastatic cancer. METHODS A literature search focusing on the regulators of anoikis in human cancer was performed on the Medline, Embase and Scopus databases. RESULTS Mcl-1, Cav-1, Bcl-(xL), cFLIP, 14-3-3ζ and Bit1 appear to regulate anoikis in human cancer by participating in the intrinsic apoptotic pathway, extrinsic apoptotic pathway or caspase-independent pathways. Mcl-1, Cav-1, Bcl-(xL), cFLIP and 14-3-3ζ are suppressors of anoikis, and their upregulation confers anoikis resistance to cancer cells. Bit1 is a promoter of anoikis and is downregulated to confer anoikis resistance in metastatic cancer. CONCLUSION Anoikis is a complex process involving the crosstalk between different signalling pathways. The dysregulated expression of key regulators of anoikis that participate in these signalling pathways promotes anoikis resistance in human cancer. These regulators of anoikis might therefore be the targets for developing therapies to overcome anoikis resistance in metastatic cancer.

Long-term nitric oxide exposure enhances lung cancer cell migration. BIOMED RESEARCH INTERNATIONAL 2013; 2013:186972.

Abstract
Nitric oxide (NO) found in the vicinity of lung cancer cells may play a role in the regulation of cancer cell behaviors. To explore the possible effects of NO on cell motility, human lung cancer cells were exposed to nontoxic concentrations of NO for 0–14 days, and the migratory characteristics of the cells were determined. The present study found that long-term treatment with NO significantly enhanced cell migration in a dose- and time-dependent manner. Furthermore, we found that the increased migratory action was associated with the increased expression of caveolin-1 (Cav-1), which in turn activated the focal adhesion kinase (FAK) and ATP-dependent tyrosine kinase (Akt) pathways. Notably, the NO-treated cells exhibited an increased number of filopodia per cell, as well as an increase in the levels of cell division cycle 42 (Cdc42) protein. Together, these results indicate that extended NO exposure has a novel effect on cell migration through a Cav-1-dependent mechanism, a finding that strengthens our understanding of cancer biology.

Abstract
The knowledge regarding the role of caveolin-1 (Cav-1) protein on endothelium adhesion of cancer cells is unclear. The present study revealed that Cav-1 plays a negative regulatory role on cancer-endothelium interaction. Endogenous Cav-1 was shown to down-regulate during cell detachment and the level of such a protein was conversely associated with tumor-endothelial adhesion. Furthermore, the ectopic overexpression of Cav-1 attenuated the ability of the cancer cells to adhere to endothelium while shRNA-mediated Cav-1 knock-down exhibited the opposite effect. We found that cell detachment increased cellular hydrogen peroxide and hydroxyl radical generation and such reactive oxygen species (ROS) were responsible for the increasing interaction between cancer cells and endothelial cells through vascular endothelial cell adhesion molecule-1 (VCAM-1). Importantly, Cav-1 was shown to suppress hydrogen peroxide and hydroxyl radical formation by sustaining the level of activated Akt which was critical for the role of Cav-1 in attenuating the cell adhesion. Together, the present study revealed the novel role of Cav-1 and underlying mechanism on tumor adhesion which explain and highlight an important role of Cav-1 on lung cancer cell metastasis.

Abstract
Advance therapies which effectively reduce mortality in lung cancer patients become a global health challenge nowadays. Sufficient knowledge regarding cellular and molecular basis of cancer progression and metastasis would possibly help in the development of novel and effective strategies for the treatment of this disease. This review focuses on the information regarding the role and mechanism of caveolin-1 (Cav-1) protein on anoikis in Non Small Cell Lung Cancer (NSCLC). NSCLC accounts of approximately 80% of all diagnosed lung cancer cases which patients frequently presented with metastatic disease. Like other cancers, caveolin-1 (Cav-1) has been shown to play an important role in regulating cancer-cells behaviors including apoptosis resistance and metastasis. Even though further investigations as well as in vivo experiments are required, these data are of great interest and may be beneficial to the development of lung cancer therapy.

Abstract
Nitric oxide (NO) has been widely recognized as an important cell-signaling molecule that regulates various physiological and pathological processes. S-nitrosylation, or covalent attachment of NO to protein sulfhydryl groups, is a key mechanism by which NO regulates protein functions and cellular processes. In this article we discuss the various roles of NO and protein nitrosylation in cancer development, with a focus on cell invasion and anoikis resistance, both of which are key determinants of cancer metastasis. We specially address some of the mechanisms by which NO-mediated S-nitrosylation modulates substrates that have putative effects on key steps of metastasis. We propose that nitrosothiol signaling is a key regulatory mechanism common to several pathways involved in cancer progression and metastasis, and identifying such a mechanism will improve our understanding of the disease process and aid in the development of novel anticancer therapeutics.
