Identification of Aging and Young Subtypes for Predicting Colorectal Cancer Prognosis and Immunotherapy Responses. Int J Mol Sci 2023; 24:ijms24021516. [PMID: 36675039 PMCID: PMC9862647 DOI: 10.3390/ijms24021516] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2022] [Revised: 01/09/2023] [Accepted: 01/10/2023] [Indexed: 01/14/2023] Open
Abstract
Colorectal cancer (CRC) is critically related to aging and severely threatens human lives. To better explore the effects of aging on CRC progression and therapy outcome, a reliable aging subtypes identification of CRC is urgently desired. Here, 28 aging-related genes associated with the CRC prognosis were selected by univariate Cox analyses. Based on these 28 genes, CRC patients were divided into the aging subtype and young subtype by non-negative matrix factorization clustering. Aging subtype and young subtype of CRC were identified with distinct molecular features and clinical prognosis. The aging subtype was characterized by upregulation of senescence-associated secretory phenotype, higher frequencies of TP53 and immune checkpoint molecules, and high sensitivity to protein kinase and angiogenesis inhibitors. Furthermore, 14 genes were selected by LASSO penalized Cox regression analyses for aging-related risk signature construction. The constructed aging risk signature exhibited good prediction and the nomogram showed robust discrimination power over the traditional CRC staging system. In conclusion, this study successfully established aging subtype and young subtype of CRC, which is helpful to identify patients with aging characteristics to evaluate prognosis and treatment outcomes. Introducing aging-based subtypes into clinical concern and patient prognostication provides new opportunities for personalized CRC treatment.

Clemente-González C, Carnero A. Role of the Hypoxic-Secretome in Seed and Soil Metastatic Preparation. Cancers (Basel) 2022; 14:cancers14235930.

Abstract
During tumor growth, the delivery of oxygen to cells is impaired due to aberrant or absent vasculature. This causes an adaptative response that activates the expression of genes that control several essential processes, such as glycolysis, neovascularization, immune suppression, and the cancer stemness phenotype, leading to increased metastasis and resistance to therapy. Hypoxic tumor cells also respond to an altered hypoxic microenvironment by secreting vesicles, factors, cytokines and nucleic acids that modify not only the immediate microenvironment but also organs at distant sites, allowing or facilitating the attachment and growth of tumor cells and contributing to metastasis. Hypoxia induces the release of molecules of different biochemical natures, either secreted or inside extracellular vesicles, and both tumor cells and stromal cells are involved in this process. The mechanisms by which these signals that can modify the premetastatic niche are sent from the primary tumor site include changes in the extracellular matrix, recruitment and activation of different stromal cells and immune or nonimmune cells, metabolic reprogramming, and molecular signaling network rewiring. In this review, we will discuss how hypoxia might alter the premetastatic niche through different signaling molecules.

Interleukin-6 at the Host-Tumor Interface: STAT3 in Biomolecular Condensates in Cancer Cells. Cells 2022; 11:cells11071164. [PMID: 35406728 PMCID: PMC8997981 DOI: 10.3390/cells11071164] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2022] [Revised: 03/23/2022] [Accepted: 03/28/2022] [Indexed: 12/26/2022] Open
Abstract
It was recognized over 30 years ago that the polyfunctional cytokine interleukin-6 (IL-6) was an almost invariant presence at the host-tumor interface. The IL-6 in the tumor microenvironment was produced either by the cancer cell or by host stromal cells, or by tumor-infiltrating immune cells, or all of them. IL-6 effects in this context included local changes in tumor cell-cell and cell-substrate adhesion, enhanced motility, epithelial to mesenchymal transformation (EMT), and changes in cell proliferation rates in both solid tumors as well as hematologic dyscrasias. Locally produced IL-6 enhanced cancer-targeting functions of tumor-infiltrating macrophages and immune cells. Additionally, the sex-biased phenotype of certain cancers [e.g., hepatocellular carcinoma (HCC) which is 3-5-fold more common in men] was related to the inhibition of macrophage-derived IL-6 production by estradiol-17β (E2). In many circumstances, locally produced IL-6 reached the peripheral circulation and elicited systemic effects such as cachexia and paraneoplastic syndrome (including fever, increased erythrocyte sedimentation rate, increased levels of C-reactive protein in serum, hypoalbuminemia). This review highlights the EMT produced by IL-6 in cancer cells, as well as mechanisms underlying sex bias in HCC, enhanced IL-6 expression in cancer cells resulting from mutations in p53, consequent alterations in STAT3 transcriptional signaling, and the newer understanding of STAT3 nuclear bodies in the cancer cell as phase-separated biomolecular condensates and membraneless organelles (MLOs). Moreover, the perplexing issue of discrepant measurements of IL-6 in human circulation using different assays, especially in patients undergoing immunotherapy, is discussed. Additionally, the paradoxical chaperone (enhancing) effect of anti-IL-6 “neutralizing” antibodies on IL-6 in vivo and consequent limitations of immunotherapy using anti-IL-6 mAb is considered.

Senescent tumor cells: an overlooked adversary in the battle against cancer. Exp Mol Med 2021; 53:1834-1841.

Abstract
AbstractSenescent cells in cancer tissue, including senescent fibroblasts and macrophages, have been reported to increase the malignant potency of cancer cells by secreting senescence-associated secretory phenotype (SASP). Otherwise, Senescence of tumor cells has been believed to inhibit tumor growth by halting the massive proliferation and increasing the chances of immune clearance. In particular, senescent tumor cells (STCs) have been thought that they rarely exist in carcinomas because oncogene-induced senescence needs to be overcome for protumorigenic cells to become malignant. However, recent studies have revealed that a considerable number of STCs are present in cancer tissue, even in metastatic sites. In fact, STCs are widely involved in cancer progression by leading to collective invasion and building a cytokine barrier to protect nonsenescent tumor cells from immune attack. Furthermore, therapy-induced STCs can induce tumor progression and recurrence by increasing stemness. However, obscure causative factors and their heterogeneity in various cancers make it difficult to establish the physiological role of STCs. Here, we summarize and review the current knowledge of the pathophysiology and role of STCs. We also outline the current status of therapeutic strategies for directly removing STCs or modulating the SASPs to maximize the positive functions of STCs while suppressing the negative functions.

Abstract
Over recent decades, the field of cellular senescence has attracted considerable attention due to its association with aging, the development of age-related diseases and cancer. Senescent cells are unable to proliferate, as the pathways responsible for initiating the cell cycle are irreversibly inhibited. Nevertheless, senescent cells accumulate in tissues and develop a pro-inflammatory secretome, known as the senescence-associated secretory phenotype (SASP), which can have serious deleterious effects if not properly regulated. There is increasing evidence suggesting senescent cells contribute to different stages of carcinogenesis in different anatomical sites, mainly due to the paracrine effects of the SASP. Thus, a new therapeutic field, known as senotherapeutics, has developed. In this review, we aim to discuss the molecular mechanisms underlying the senescence response and its relationship with cancer development, focusing on the link between senescence-related inflammation and cancer. We will also discuss different approaches to target senescent cells that might be of use for cancer treatment.

Cross-Sectional and Longitudinal Relationships Between Inflammatory Biomarkers and Frailty in Community-dwelling Older Men: The Concord Health and Ageing in Men Project. J Gerontol A Biol Sci Med Sci 2020; 74:835-841. [PMID: 28977375 DOI: 10.1093/gerona/glx142] [Citation(s) in RCA: 30] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2017] [Accepted: 07/17/2017] [Indexed: 01/02/2023] Open
Abstract
BACKGROUND Previous studies demonstrated associations between IL-6 and frailty, but associations between a wide range of cytokines, chemokines, and growth factors with prevalent and incident frailty has not been studied. METHODS Community-dwelling men aged more than 75 enrolled in the 5-year and 8-year follow-up of the CHAMP study were assessed. Twenty-seven inflammatory biomarkers were measured using the Bio-Plex Pro Human Cytokine 27-plex Assay kit at 5-year follow-up. Frailty was determined using the Fried frailty phenotype (FP) and Rockwood frailty index (FI) at both time-points. Age, body mass index, smoking, alcohol, and comorbidity were also assessed. RESULTS In cross-sectional analysis of the 5-year follow-up, the unadjusted odds ratio (OR) for frail versus robust evaluated by the FP showed significant associations for IL-6 (OR: 1.56, 95% confidence interval [CI]: 1.23-1.98) and IL-8 (OR: 1.28, 95% CI: 1.00-1.63). IL-6 remained significantly associated in the age-adjusted (OR: 1.58, 95% CI: 1.21-2.05) and multivariable-adjusted model (OR: 1.54, 95% CI: 1.16-2.05). No associations were observed between pre-frail versus robust. In longitudinal unadjusted analysis, IL-8 (OR: 1.32, 95% CI: 1.03-1.70) and IP-10 (OR: 1.32, 95% CI: 1.03-1.70) at 5-year predicted incident frailty at 8-year follow-up. IL-8 remained longitudinally associated with incident frailty after age (OR: 1.34, 95% CI: 1.03-1.75) but not multivariable (OR: 1.20, 95% CI: 0.98-1.70) adjustment. Similar results were seen using the FI. None of the other biomarkers had significant associations with incident frailty. CONCLUSIONS Our findings suggest that IL-6 and IL-8 may be cross-sectionally associated with frailty and that all measured inflammatory biomarkers were not causally related to frailty. Together with previous studies, the results suggest that frailty is specifically linked to IL-6 and IL-8 rather than simply representing a nonspecific pan-inflammatory condition.

Abstract
The aim of the study is to analyse the expression of Interleukin-6 receptor in different human gastric tissue and to correlate with the clinicopathological features of the patients. Immunohistochemistry was done against the IL-6R antibody and the Q-score was calculated from the staining pattern. Higher Q-scores were observed in tumour cells than the adjacent normal cells which were statistically significant. We also observed a significant correlation between the expressions of IL-6R and the clinicopathological features These findings suggest that IL-6R may represent as a therapeutic target for gastric carcinoma and serve as a prognostic indicator, as well.

Abstract
Chronic kidney disease (CKD) is a clinical model of premature ageing characterized by progressive vascular disease, systemic inflammation, muscle wasting and frailty. The predominant early vascular ageing (EVA) process mediated by medial vascular calcification (VC) results in a marked discrepancy between chronological and biological vascular age in CKD. Though the exact underlying mechanisms of VC and EVA are not fully elucidated, accumulating evidence indicates that cellular senescence - and subsequent chronic inflammation through the senescence-associated secretary phenotype (SASP) - plays a fundamental role in its initiation and progression. In this review, we discuss the pathophysiological links between senescence and the EVA process in CKD, with focus on cellular senescence and media VC, and potential anti-ageing therapeutic strategies of senolytic drugs targeting cellular senescence and EVA in CKD.

Abstract
Senescent cells activate genetic programmes that irreversibly inhibit cellular proliferation, but also endow these cells with distinctive metabolic and signalling phenotypes. Although senescence has historically been considered a protective mechanism against tumourigenesis, the activities of senescent cells are increasingly being associated with age-related diseases, including cancer. An important feature of senescent cells is the secretion of a vast array of pro-inflammatory cytokines, chemokines, and growth factors collectively known as the senescence-associated secretory phenotype (SASP). Recent research has shown that SASP paracrine signalling can mediate several pro-tumourigenic effects, such as enhancing malignant phenotypes and promoting tumour initiation. In this review, we summarise the paracrine activities of senescent cells and their role in tumourigenesis through direct effects on growth and proliferation of tumour cells, tumour angiogenesis, invasion and metastasis, cellular reprogramming and emergence of tumour-initiating cells, and tumour interactions with the local immune environment. The evidence described here suggests cellular senescence acts as a double-edged sword in cancer pathogenesis, which demands further attention in order to support the use of senolytic or SASP-modulating compounds for cancer treatment.

Abstract
Senescent cells may promote tumour progression through the activation of a senescence-associated secretory phenotype (SASP), whether these cells are capable of initiating tumourigenesis in vivo is not known. Expression of oncogenic β-catenin in Sox2+ young adult pituitary stem cells leads to formation of clusters of stem cells and induction of tumours resembling human adamantinomatous craniopharyngioma (ACP), derived from Sox2- cells in a paracrine manner. Here, we uncover the mechanisms underlying this paracrine tumourigenesis. We show that expression of oncogenic β-catenin in Hesx1+ embryonic precursors also results in stem cell clusters and paracrine tumours. We reveal that human and mouse clusters are analogous and share a common signature of senescence and SASP. Finally, we show that mice with reduced senescence and SASP responses exhibit decreased tumour-inducing potential. Together, we provide evidence that senescence and a stem cell-associated SASP drive cell transformation and tumour initiation in vivo in an age-dependent fashion.

Abstract
Oncostatin M (OSM) is an interleukin-6-like inflammatory cytokine reported to play a role in a number of pathological processes including cancer. Full-length OSM is expressed as a 26 kDa protein that can be proteolytically processed into 24 kDa and 22 kDa forms via removal of C-terminal peptides. In this study, we examined both the ability of OSM to bind to the extracellular matrix (ECM) and the activity of immobilized OSM on human breast carcinoma cells. OSM was observed to bind to ECM proteins collagen types I and XI, laminin, and fibronectin in a pH-dependent fashion, suggesting a role for electrostatic bonds that involves charged amino acids of both the ECM and OSM. The C-terminal extensions of 24 kDa and 26 kDa OSM, which contains six and thirteen basic amino acids, respectively, enhanced electrostatic binding to ECM at pH 6.5-7.5 when compared to 22 kDa OSM. The highest levels of OSM binding to ECM, though, were observed at acidic pH 5.5, where all forms of OSM bound to ECM proteins to a similar extent. This indicates additional electrostatic binding properties independent of the OSM C-terminal extensions. The reducing agent dithiothreitol also inhibited the binding of OSM to ECM suggesting a role for disulfide bonds in OSM immobilization. OSM immobilized to ECM was protected from cleavage by tumor-associated proteases and maintained activity following incubation at acidic pH for extended periods of time. Importantly, immobilized OSM remained biologically active and was able to induce and sustain the phosphorylation of STAT3 in T47D and ZR-75-1 human breast cancer cells over prolonged periods, as well as increase levels of STAT1 and STAT3 protein expression. Immobilized OSM also induced epithelial-mesenchymal transition-associated morphological changes in T47D cells. Taken together, these data indicate that OSM binds to ECM in a bioactive state that may have important implications for the development of chronic inflammation and tumor metastasis.

Abstract
IL-6 signaling plays a prominent role in tumorigenesis and metastasis. In this review we discuss the recent evidence describing the tumor intrinsic and extrinsic functions of this signaling pathway. Although blockade of this pathway in pre-clinical models leads to a reduction in tumor growth and metastasis, its clinical success is less evident. Thus, identifying the features of tumors/patients that predict response to anti-IL6 therapy are needed.

Abstract
Cell-to-cell adhesion is an important aspect of malignant spreading that is often observed in images from the experimental cell biology literature. Since cell-to-cell adhesion plays an important role in controlling the movement of individual malignant cells, it is likely that cell-to-cell adhesion also influences the spatial spreading of populations of such cells. Therefore, it is important for us to develop biologically realistic simulation tools that can mimic the key features of such collective spreading processes to improve our understanding of how cell-to-cell adhesion influences the spreading of cell populations. Previous models of collective cell spreading with adhesion have used lattice-based random walk frameworks which may lead to unrealistic results, since the agents in the random walk simulations always move across an artificial underlying lattice structure. This is particularly problematic in high-density regions where it is clear that agents in the random walk align along the underlying lattice, whereas no such regular alignment is ever observed experimentally. To address these limitations, we present a lattice-free model of collective cell migration that explicitly incorporates crowding and adhesion. We derive a partial differential equation description of the discrete process and show that averaged simulation results compare very well with numerical solutions of the partial differential equation.

Abstract
Chronic low-grade inflammation plays an important role in the pathogenesis of several cancer forms including breast cancer. The pleiotropic cytokine IL-6 is a key player in systemic inflammation, regulating both the inflammatory response and tissue metabolism during acute stimulations. Here, we review the associations between IL-6 and breast cancer ranging from in vitro cell culture studies to clinical studies, covering the role of IL-6 in controlling breast cancer cell growth, regulation of cancer stem cell renewal, as well as breast cancer cell migration. Moreover, associations between circulating IL-6 and risk of breast cancer, prognosis for patients with prevalent disease, adverse effects and interventions to control systemic IL-6 levels in patients are discussed. In summary, direct application of IL-6 on breast cancer cells inhibits proliferation in estrogen receptor positive cells, while high circulating IL-6 levels are correlated with a poor prognosis in breast cancer patients. This discrepancy reflects distinct roles of IL-6, with elevated systemic levels being a biomarker for tumor burden, physical inactivity, and impaired metabolism, while local intratumoral IL-6 signaling is important for controlling breast cancer cell growth, metastasis, and self renewal of cancer stem cells.

Abstract
Aging is the largest risk factor for most chronic diseases, which account for the majority of morbidity and health care expenditures in developed nations. New findings suggest that aging is a modifiable risk factor, and it may be feasible to delay age-related diseases as a group by modulating fundamental aging mechanisms. One such mechanism is cellular senescence, which can cause chronic inflammation through the senescence-associated secretory phenotype (SASP). We review the mechanisms that induce senescence and the SASP, their associations with chronic disease and frailty, therapeutic opportunities based on targeting senescent cells and the SASP, and potential paths to developing clinical interventions.

Abstract
The vast majority of all agents used to directly kill cancer cells (ionizing radiation, most chemotherapeutic agents and some targeted therapies) work through either directly or indirectly generating reactive oxygen species that block key steps in the cell cycle. As mesenchymal cancers evolve from their epithelial cell progenitors, they almost inevitably possess much-heightened amounts of antioxidants that effectively block otherwise highly effective oxidant therapies. Also key to better understanding is why and how the anti-diabetic drug metformin (the world's most prescribed pharmaceutical product) preferentially kills oxidant-deficient mesenchymal p53− −cells. A much faster timetable should be adopted towards developing more new drugs effective against p53− − cancers.

Abstract
We study MCF-7 breast cancer cell movement in a transwell apparatus. Various experimental conditions lead to a variety of monotone and nonmonotone responses which are difficult to interpret. We anticipate that the experimental results could be caused by cell-to-cell adhesion or volume exclusion. Without any modeling, it is impossible to understand the relative roles played by these two mechanisms. A lattice-based exclusion process random-walk model incorporating agent-to-agent adhesion is applied to the experimental system. Our combined experimental and modeling approach shows that a low value of cell-to-cell adhesion strength provides the best explanation of the experimental data suggesting that volume exclusion plays a more important role than cell-to-cell adhesion. This combined experimental and modeling study gives insight into the cell-level details and design of transwell assays.

Abstract
The ability of the host to mount an appropriate immune response to aberrant cells is one factor that determines prognosis in cancer patients. Naturally occurring regulatory T cells (T regs; CD4+ CD25+ cells) are key regulators of peripheral tolerance. It has been suggested that high levels of T regs are detrimental to the patient in some forms of cancer, but the role of these antigen-specific cells in individuals with colorectal cancers with high levels of microsatellite instability is unknown. Herein, we examined the ability of individuals with MSI-H or microsatellite stable colon cancer to recruit lymphocytes to the tumor site. Immunohistochemical staining was performed on archived paraffin-embedded specimens from a total of 38 individuals with MSI-H (n = 25) or MSS (n = 13) colon cancers to determine the proportion of CD3+, CD8+ and CD25+ cells infiltrating the tumor site. Patients with MSI-H colon cancers had increased percentages of CD8+ TILs (cytotoxic T cells) as compared to individuals with MSS colon cancer (47.3 vs. 24.04% of the infiltrate CD8+, respectively). No differences in the levels of CD25+ T cells were observed between individuals with MSI-H colon cancers and MSS colon cancers (0.53 vs. 0.54% CD25+, respectively). Together, these data suggest that the survival advantage enjoyed by patients with MSI-H colorectal cancer may, in part, be attributed to the increased cytolytic response, but not to an antigen-specific immunosuppressive response in MSS patients.

Abstract
BACKGROUND The process of progression and spread of cancer is not easily replicated in animal models and is difficult to examine in vitro. This is particularly true for human primary breast carcinoma cells, whose in vitro growth is shown to be limited to one or two passages in monolayer culture. Three-dimensional (3D) growth of breast cancer cells suggests that cell aggregates grown in this manner have many similarities to in vivo behavior. MATERIALS AND METHODS Primary tumors obtained from five breast cancer patients were grown in 3D cultures using the rotating-wall vessel bioreactor. Tumor aggregates were assessed for DNA ploidy, cell cycle kinetics, and expression of tumor markers and cytokines. Comparisons between fresh tumor cells and 3D aggregates were performed. RESULTS All five breast cancers were found to be aneuploid after 3D culture, with elevated S-phase fractions. Reverse transcription-polymerase chain reaction analyses revealed mRNA expression of HER2/neu, H-ras, K-ras, p53, transforming growth factor-alpha, transforming growth factor-beta, interleukin-1, and interleukin-6 in 3D-grown tumor cells; in most cases, expression appeared increased when compared with mRNA obtained from freshly isolated primary tumor cells. CONCLUSIONS After prolonged 3D growth in the rotating wall bioreactor, complex tissue-like constructs of primary breast tumor cells exhibited significantly increased proliferative activity in conjunction with oncogene activation and developed into aggressive aneuploid populations.

Abstract
The trabecular meshwork (TM)/Schlemm's canal (SC) outflow pathway is the tissue responsible for maintaining normal levels of intraocular pressure. In the present study, we investigate the effects of mechanical stress on the expression of IL-6 in the TM meshwork, as well as the effects of this cytokine on outflow pathway function. Application of cyclic mechanical stress to human TM primary cultures resulted in a statistically significant increase in both secretion and transcription of IL-6, compared to nonstressed controls. Addition of TGF-beta1, which has been reported to be upregulated in TM cells under mechanical stress, also induced a significant activation of both the transcription and secretion of IL-6. Moreover, anti-TGF-b1 antibodies partially blocked the stretch-induced IL-6 production. Injection of IL-6 into perfused porcine anterior segments resulted in a 30% increase in outflow facility, as well as increased permeability through SC cell monolayers. These results suggest a role for IL-6 in the homeostatic modulation of aqueous humor outflow resistance.

Abstract
The cytokine receptor gp130 is the common signaling subunit of receptors used by the interleukin (IL)-6 cytokine family. gp130 is widely expressed in breast cancer cell lines and primary tumors. The role of gp130 in breast cancer in vivo is unknown. To study the effect of gp130 inhibition in breast cancer, endogenous gp130 signaling in breast cancer cell lines was blocked with a dominant-negative gp130 protein (DN gp130). DN gp130 inhibited constitutive Stat3 activation in breast cancer cells. Both gp130 and epidermal growth factor receptor (EGFR) have been implicated in constitutive Stat3 activation in breast cancer. There are known physical and functional interactions between gp130 and EGFR. Consistent with this, we show that DN gp130 inhibits signaling downstream of the EGFR in breast cancer cells. The effect of DN gp130 on breast cancer in vivo was assessed with an orthotopic nude mouse model. DN gp130 MDA-231 cells had markedly decreased engraftment, size, and metastasis compared with control cells. These results are particularly striking considering that DN gp130-expressing breast cancer cells grow faster in vitro. We hypothesized that DN gp130 expression results in inhibition of invasion and metastasis in vivo. Marked angiogenesis was present in tumors from control animals and was absent in tumors from DN gp130 animals. We additionally show that tissue inhibitor of metalloproteinase-3, an inhibitor of tumor invasion and angiogenesis, is up-regulated in both MDA-231 DN gp130 cells and tumors. These results, in light of the availability of several potential pharmacological inhibitors of gp130, suggest novel approaches to breast cancer therapy.

Abstract
BACKGROUND Both growth and motility of various tumor cells have been shown to be influenced by surrounding cells such as lymphocytes, histiocytes and fibroblasts through various cytokines, growth factors and extracellular matrices. The role of cytokines and extracellular matrices produced by lymphocytes, histiocytes and fibroblasts on migration and invasion of breast carcinoma cells has not been fully investigated METHODS We investigated the effect of hepatocyte growth factor (HGF), interleukin (IL)-6, IL-8, IL-11, soluble type IV collagen and soluble laminin on the migration of 3 human breast carcinoma cell lines, MDA-MB-231, MCF-7 and T-47D, using a cell culture insert and a biocoat matrigel invasion chamber to assess migration across a matrigel-coated polyethylene telephtalate membrane. RESULTS HGF, IL-6, IL-11 and IL-8 induced significant migration of MDA-MB-231 cells depending on the dose of each cytokine. However, type IV collagen and laminin inhibited migration of MDA-MB-231 cells. In contrast, IL-8 inhibited migration of MCF-7 cells and IL-6 induced significant migration of T-47D cells, while no other cytokine or extracellular matrix induced significant migration of MCF-7 and T-47D cells. Only HGF induced significant invasion of MDA-MB-231 cells depending on the dose. MCF-7 and T-47D cells did not invade in response to any of the cytokines and extracellular matrices tested. CONCLUSIONS These results suggest the possibility that the potency of chemotaxis or chemoinvasion differs according to the breast carcinoma cell line and that various cytokines and extracellular matrices secreted by lymphocytes, histiocytes and fibroblasts in the stroma of breast carcinoma can affect the invasion of breast carcinoma cells.

Abstract
The mucin-like glycoprotein episialin (MUC1) is highly overproduced by a number of human carcinomas. We have shown previously in a variety of mammalian cell lines that overexpression of this very large transmembrane molecule diminishes cellular adhesion, suggesting that episialin/MUC1 overexpression may play an important role in tumor invasion and metastasis. By using in situ hybridization, we show here that episialin/MUC1 mRNA expression can be increased more than 10-fold in breast carcinoma cells relative to the expression in adjacent normal breast epithelium. In search of the molecular mechanism of this overexpression, we observed that the episialin/MUC1 promoter contains a candidate binding site for transcription factors of the STAT family approximately 500 base pairs upstream of the transcription start site. Cytokines and/or growth factors such as interleukin-6 or interferon-gamma can activate STATs. In the human breast carcinoma cell line T47D, both compounds are able to stimulate transcription of a luciferase reporter gene under the control of a 750-base pair MUC1 promoter fragment proximal to the transcription start site. The observed increase is entirely mediated by the single STAT-binding site, since mutation of this site abolishes stimulation of the reporter by interleukin-6 and interferon-gamma. In addition, mutation of the STAT site also decreased the promoter activity in nonstimulated T47D cells, suggesting that the STAT-binding site is among the elements that are involved in the overexpression of MUC1 in tumor cells.

Abstract
We investigated the antitumour effects of interleukin 6 (IL-6) on hepatocarcinoma HepG2 cells, endowed with high levels of a mutated, non-degradable, beta-catenin. IL-6 produced minimal growth-inhibitory effects and no apoptosis or gross changes in cell adhesion. Interestingly, however, it caused a consistent decrease in the cytoplasmic levels of wild-type, but not of mutated, beta-catenin protein. There was no effect on E-cadherin or gamma-catenin and a reduction in alpha-catenin occurred only at high concentrations. IL-4, a non-related cytokine, did not modify the content of beta-catenin. IL-6 did not influence beta-catenin mRNA levels. LiCl, a potent inhibitor of Glycogen Synthase Kinase 3beta (GSK3beta) activity, abrogated the IL-6-induced inhibition of wild-type beta-catenin. This indicates that IL-6 can affect wild-type beta-catenin through a post-transcriptional mechanism, probably involving degradation of the protein. This effect might be related to the growth-regulatory activities of IL-6 in other situations, but can not counteract the oncogenic expression of mutated beta-catenin in HepG2 cells or possibly in other tumour cells with similar gene mutations.

Abstract
Directional migration of capillaries towards tumour implants is generally assumed to be regulated by chemotaxis. Preliminary evidence has also been presented for the existence of a reverse chemotactic signalling pathway, with capillaries attracting tumour cells via paracrine factors. By using a variety of endothelial cell types and tumour cell lines, this study has systematically investigated chemotaxis between endothelial cells and tumour cells in two- and three-dimensional systems. Checkerboard analysis revealed faint attraction of human umbilical vein endothelial cells (HUVECs), but not porcine aortic endothelial cells (PAECs), by tumour cells. In reverse, both PAECs and HUVECs potently induced chemotactic migration of tumour cells. Using a microcarrier-based fibrin gel assay, directional migration of endothelial cells towards tumour cells was not observed. In reverse, tumour cells were strongly attracted by endothelial cells. Identification of endothelium-derived chemotactic molecules may provide a valuable approach for the treatment of tumour metastasis.

Abstract
To assess the role of interleukin-4 (IL-4) and interleukin-13 (IL-13) in colon cancer cell-cell adhesion, we investigated the effect of both cytokines in human colon cancer cell line, colo205 cell-cell adhesion. IL-4 receptor was expressed on the cell surface of colo205, and recombinant IL-4 inhibited colo205 cell-cell adhesion in a dose-dependent fashion without inhibiting cell proliferation. Flow cytometric analysis revealed that monoclonal antibodies (mAbs) directed against E-cadherin and carcinoembryonic antigen (CEA) inhibited colo205 cell-cell adhesion and IL-4 significantly inhibited the expression of E-cadherin and CEA. IL-13 also inhibited colo205 cell-cell adhesion. These results indicated that IL-4 and IL-13 inhibited colon cancer cell-cell adhesion by down-regulation of E-cadherin and CEA molecules. We then investigated the expression of both cytokines from freshly isolated colon cancer tumour-infiltrating lymphocytes (TILs). With reverse transcription-polymerase chain reaction and flow cytometric analysis, we demonstrated that colon TILs expressed IL-4 and IL-13 mRNA and protein. These results suggest that Th 2 type cytokines IL-4 and IL-13 locally-produced from TILs may regulate colon cancer adhesion by down-regulation of adhesion molecules.

Abstract
Oncostatin M (OSM) is a member of the interleukin 6 (IL-6) family of cytokines and was originally identified by its ability to inhibit proliferation of melanoma cells but augment the growth of normal fibroblasts. OSM has pleiotropic effects on many different cell types, but here we focus on its ability to inhibit the proliferation of cell lines derived from several tumour types, including breast carcinoma, ovarian cancer, melanoma, glioma and lung carcinoma. The inhibition of proliferation of several cancer cell lines by OSM is associated with alterations in cellular morphology and with phenotypic changes that are consistent with the induction of differentiation of these cells. These observations raise the possibility that OSM could have therapeutic potential.

Abstract
We used Transwell chambers to study separately cellular motility and invasion. In order to assess the cellular motility, polycarbonate microporous filters were coated with extracellular matrix proteins which adsorbed on the filters without clogging the pores. To investigate the invasive behavior of tumor cells, filters were covered with a layer of Matrigel which clogged the pores. The motility and the invasion of breast cancer cell lines (MDA-MB-231, MCF-7/6 and MCF-7/AZ cells) were assessed quantitatively in different culture media: defined (serum-free), serum-containing and normal human fibroblast MRC-5 conditioned media. In serum-containing medium, tumor cells migrated and invaded through the coated and covered filters. Their motility and invasion potentials were considerably lower in defined medium, whereas medium conditioned by MRC-5 fibroblasts stimulated both motility and invasion but not growth. The MRC-5 conditioned medium induced also the spreading of clusters of MCF-7/6 cells grown on Matrigel-coated plates.

Abstract
Cell motility is an important factor in the process of invasion and metastasis of tumor. In this study, the relationship between cell motility and experimental metastatic potential was examined using two human pancreatic cancer cell lines, SW1990 and PANC-1. Serum-free conditioned medium from the highly metastatic cell line SW1990 was found to contain a factor that stimulated the migration of and induced a fibroblast-like morphological change in the weakly metastatic cell line PANC-1. Preincubation of PANC-1 cells with SW1990 conditioned medium (SW-C.M.) induced liver metastasis following splenic injection of PANC-1 cells in nude mice, although no liver metastasis was observed without pretreatment of SW-C.M. This factor, temporarily termed PDMF (pancreatic cancer-derived motility factor) is a heparin non-binding protein having a molecular weight of 40 kDa calculated by gel-filtration HPLC which acts not only chemotactically but also chemokinetically, and also acts mainly in a paracrine fashion. However, this factor had no effect on the proliferation of PANC-1 cells; it therefore appears to be a so-called motility factor. Only TGF-beta1 and IL-6 were recognized in the SW-C.M. among cytokines thought to stimulate cell motility. These cytokines stimulated the motility of PANC-1 cells, but differed from PDMF in the neutralizing test with antibody against these cytokines. Results of characterization and preliminary purification suggest that this factor may be a novel motility factor. The above findings suggest that this motility factor may play an important role in the invasion and metastasis of pancreatic cancer, and complete purification of it will be useful in elucidating the mechanism of progression of cancer and designing a strategy for inhibition of invasion and metastasis of pancreatic cancer.

Abstract
Interleukin-6 is associated with poor prognosis in breast cancer. Expression of GP96, a glucose regulated stress protein, is related to drug resistance in tumor cells. Interleukin-6 has previously been shown to induce GP96 expression in a murine myeloblastic cell line. BT474 or MDA-MB231 cells were incubated with recombinant Interleukin-6 (100 to 750 U/ml) for 24 hr. To establish a time course for GP96 induction, MDA-MB231 cells were incubated with 250 U/ml recombinant interleukin-6 for 0-48 hr. Following incubation, cells were washed twice in phosphate-buffered saline (PBS) and cell lysates were prepared by adding 100 microliters of PBS and freezing at -20 degrees C. GP96 was assessed by immunoblotting. Breast tumor tissue and histologically normal breast tissue were obtained within 1 hr of resection and flash frozen in liquid nitrogen. Tissue was homogenized in ice-cold PBS and cell debris was pelleted by centrifugation at 300g at 4 degrees C for 5 min. Supernatants were collected and assayed for interleukin-6 by ELISA, and GP96 by immunoblotting. Both interleukin-6 (P < 0.001) and GP96 are elevated in breast tumor tissue compared to histologically normal tissue. Interleukin-6 (> or = 250 U/ml for > or = 12 hr) induces GP96 in the metastatic breast cancer cell line, MDA-MB231, but has no effect on GP96 levels in the primary cell line, BT474. Elevated interleukin-6 in breast tumors may induce GP96 expression in tumor cells conferring a survival advantage by rendering them resistant to cytotoxic therapy and other forms of stress.

Abstract
Psoralen plus UVA (320-400 nm radiation; PUVA) is a highly effective therapy for cutaneous diseases caused by skin infiltration with normal or neoplastic T-lymphocytes. In comparing the effects of pharmacologically relevant, low-dose PUVA treatment on growth of human keratinocytes, peripheral blood leukocytes (PBMC), and T-lymphocyte cell lines, we determined that PBMC or T-lymphocytes were > 50-fold more sensitive to cytotoxic effects of PUVA, while antiproliferative effects were produced by similar PUVA levels in all cell types. Low doses of PUVA (10 ng/mL 8-methoxypsoralen and 1-2 J/cm2) were highly cytotoxic for phytohemagglutinin-activated normal lymphocytes or transformed T-lymphocytes as assessed by two viability assays and by flow cytofluorometry. Altered lymphocyte morphology, nuclear fragmentation, TUNEL+ nuclei or nuclear fragments, and the appearance of a sub-G1 DNA peak indicated that cell death occurred by apoptosis, beginning about 1 day after PUVA treatment and continuing for several days thereafter. From assessment of cell cycle progression in mimosine-synchronized cells, PUVA treatment markedly slowed cell cycle progression, eventually producing cell cycle arrest and apoptotic entry. We propose that the probable basis for disease remissions (psoriasis, cutaneous T-cell lymphoma) produced by PUVA treatment is through selective cytotoxic effects on clonal T-lymphocyte populations that are concentrated in diseased skin.

Abstract
BACKGROUND Two pancreatic cancer cell lines, the highly invasive and metastatic cell line PC-1.0 and the weakly invasive and rarely metastatic cell line PC-1, were established from a pancreatic ductal carcinoma induced by N-nitrosobis (2-oxopropyl) amine in a Syrian golden hamster. METHODS The cancer cell dissociation activity in serum-free conditioned medium of PC-1.0 cells was partially purified using a heparin column, a hydroxylapatite column, anion exchange, and gel filtration high-performance liquid chromatography. Several biologic properties of the partially purified activity were evaluated. RESULTS Two cell lines exhibited different growth morphologic changes in vitro: the weakly invasive cell line PC-1 formed islandlike colonies, and the highly invasive cell line PC-1.0 grew mainly as single cells. The conditioned medium of PC-1.0 cells induced dissociation of islandlike colonies and morphologic changes of PC-1 cells to elongated cells, with a high frequency of pseudopodia formation similar to the morphologic findings of PC-1.0 cells. The dissociation activity did not bind to the heparin column and had an apparent molecular mass of > 400 kDa, as deduced from gel filtration. Several immunoreactive proteinous bands were observed in immunoblotting analysis using a polyclonal blocking antibody. The partially purified activity enhanced cell motility, chemoinvasion, and cell adhesion to plastic plates and fibronectin. CONCLUSIONS Highly invasive and metastatic PC-1.0 cells produce a soluble proteinous factor, called "dissociation factor" (DF), which induces cell dissociation of weakly invasive and rarely metastatic PC-1 cells. It seems likely that DF has a role in tumor invasion and metastasis.

Abstract
E-cadherin is expressed in both the ZR-75-1-Tx and the ZR-75-1-Ro sublines of ductal breast carcinoma cells and is concentrated at cell-cell borders as shown by immunocytochemical examination. Free cell borders generally show no or little staining. The localized decrease in E-cadherin expression observed after interleukin 6 (IL-6) treatment of either subline correlates with the increase in free cell borders as IL-6 causes cell-cell separation. As we previously reported, many IL-6-treated ZR-75-1-Tx cells round up and detach from the substratum while ZR-75-1-Ro cells remain adherent and display prominent processes. The results are consistent with the view that E-cadherin expression is not responsible for the marked difference in the IL-6-induced phenotypes in these cell lines, although the localized decrease may play a role in cell-cell separation. ZR-75-1-Tx cells are deficient in desmosomes and show a wider intercellular space than ZR-75-1-Ro cells. Alternative mechanisms involving different aspects of the interlinked cytoskeletal and cell adhesion structures are considered to account for the IL-6-induced antimorphogenetic effect.
