Exploring the multifaceted effects of Interleukin-1 in lung cancer: From tumor development to immune modulation. Life Sci 2024; 342:122539. [PMID: 38423172 DOI: 10.1016/j.lfs.2024.122539] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Revised: 02/21/2024] [Accepted: 02/25/2024] [Indexed: 03/02/2024]
Abstract
Lung cancer, acknowledged as one of the most fatal cancers globally, faces limited treatment options on an international scale. The success of clinical treatment is impeded by challenges such as late diagnosis, restricted treatment alternatives, relapse, and the emergence of drug resistance. This predicament has led to a saturation point in lung cancer treatment, prompting a rapid shift in focus towards the tumor microenvironment (TME) as a pivotal area in cancer research. Within the TME, Interleukin-1 (IL-1) is abundantly present, originating from immune cells, tissue stromal cells, and tumor cells. IL-1's induction of pro-inflammatory mediators and chemokines establishes an inflammatory milieu influencing tumor occurrence, development, and the interaction between tumors and the host immune system. Notably, IL-1 expression in the TME exhibits characteristics such as staging, tissue specificity, and functional pluripotency. This comprehensive review aims to delve into the impact of IL-1 on lung cancer, encompassing aspects of occurrence, invasion, metastasis, immunosuppression, and immune surveillance. The ultimate goal is to propose a novel treatment approach, considering the intricate dynamics of IL-1 within the TME.

RORγt may Influence the Microenvironment of Thyroid Cancer Predicting Favorable Prognosis. Sci Rep 2020; 10:4142. [PMID: 32139737 PMCID: PMC7058012 DOI: 10.1038/s41598-020-60280-3] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2019] [Accepted: 02/07/2020] [Indexed: 11/09/2022] Open
Abstract
We aimed to investigate the role of RORγt (Retinoic acid-related orphan receptor gamma) in the tumor microenvironment of differentiated thyroid carcinoma. We retrospectively analyzed 56 patients (48 papillary and 8 follicular thyroid carcinomas). Immunohistochemical expression of RORγt was compared to other immune markers previously investigated by our group, clinical and pathological information. All patients presented cytoplasmic expression of RORγt in thyroid tumor cells. Seven (12.5%) patients presented no nuclear expression of RORγt. Positivity was few (up to 10%) in 14 patients; 10 to 50% in 5 patients (8.9%); and more than 50% in 30 patients (53.6%). Nuclear RORγt positivity was associated with absence of distant metastasis at diagnosis (p = 0.013) and the need of less cumulative doses of radioactive iodine (p = 0.039). Patients whose tumors were positive for nuclear RORγt presented higher 10-years relapse-free survival rate than those patients who were negative for RORγt (p = 0.023). We classified the patients according to the clustering of immunological immunohistochemical markers. We were able to distinguish a subset (A) of 38 patients who presented high expression of nuclear RORγt and tended to be scarce in proinflammatory immune markers. Other 16 patients integrated a second subset (B) whose tumor microenvironment accumulated proinflammatory markers and presented low expression of nuclear nuclear RORγt. Distant metastasis at diagnosis were more frequent among patients from cluster B than from cluster A (p = 0.008). Our results reinforce that the expression of RORγt together with other immune markers might help predict the prognosis of patients with thyroid cancer and help individualize clinical management.

Abstract
The CDK inhibitor SNS-032 had previously exerted promising anti-neuroblastoma activity via CDK7 and 9 inhibition. ABCB1 expression was identified as major determinant of SNS-032 resistance. Here, we investigated the role of ABCB1 in acquired SNS-032 resistance. In contrast to ABCB1-expressing UKF-NB-3 sub-lines resistant to other ABCB1 substrates, SNS-032-adapted UKF-NB-3 (UKF-NB-3rSNS- 032300nM) cells remained sensitive to the non-ABCB1 substrate cisplatin and were completely re-sensitized to cytotoxic ABCB1 substrates by ABCB1 inhibition. Moreover, UKF-NB-3rSNS-032300nM cells remained similarly sensitive to CDK7 and 9 inhibition as UKF-NB-3 cells. In contrast, SHEPrSNS-0322000nM, the SNS-032-resistant sub-line of the neuroblastoma cell line SHEP, displayed low level SNS-032 resistance also when ABCB1 was inhibited. This discrepancy may be explained by the higher SNS-032 concentrations that were used to establish SHEPrSNS-0322000nM cells, since SHEP cells intrinsically express ABCB1 and are less sensitive to SNS-032 (IC50 912 nM) than UKF-NB-3 cells (IC50 153 nM). In conclusion, we show that ABCB1 expression represents the primary (sometimes exclusive) resistance mechanism in neuroblastoma cells with acquired resistance to SNS-032. Thus, ABCB1 inhibitors may increase the SNS-032 efficacy in ABCB1-expressing cells and prolong or avoid resistance formation.

Abstract
BACKGROUND In the present study, we investigated the role of p38-p38IP signaling in the inflammation-induced promotion of epithelial-to-mesenchymal transition (EMT) in Head and Neck Squamous Cell Carcinoma (HNSCC). METHODS Quantitative RT-PCR, western blot analysis, spheroid modeling and immunohistochemical staining of human HNSCC tissue sections were used. RESULTS p38 inhibitor treated and p38 shRNA HNSCC cell lines demonstrate a significant upregulation in E-cadherin mRNA and a decrease in the mRNA expression of Snail. p38 binds to and stabilizes p38IP, a subunit of histone SPT3-TAF9-GCN5 acetyltransferase (STAGA), resulting in enhanced transcription of Snail. p38 shRNA HNSCC cell lines show a less invasive phenotype in a spheroid model. In clinical HNSCC samples, p38 interacting protein (p38IP) is significantly increased compared to adjacent normal tissue. An inverse relationship between p38, p38IP and E-cadherin is demonstrated. CONCLUSIONS Herein we provide the first report that p38-p38IP is required for the Snail-induced E-cadherin down-regulation and cell invasion in HNSCC.

Abstract
Cyclin-dependent kinases (CDKs) exert a variety of functions through regulation of the cell cycle and gene expression, thus implicating them in diverse biological processes. Recent studies have deciphered the molecular mechanisms employed by nuclear CDKs to support the expression of inflammatory mediators. Induced transcription of many proinflammatory genes is increased during the G1 phase of the cell cycle in a CDK-dependent manner. This process involves the cytokine-induced recruitment of CDK6 to the nuclear chromatin fraction where it associates with transcription factors of the NF-κB, STAT, and AP-1 families. The ability of CDK6 to trigger the expression of VEGF-A and p16(INK4A) and to recruit the NF-κB subunit p65 to its target sites is largely independent of its kinase function. The involvement of CDKs in proinflammatory gene expression also allows therapeutic targeting of their functions to interfere with tumor-promoting inflammation or chronic inflammatory diseases.

Abstract
OBJECTIVES/HYPOTHESIS The presence of regional metastases in head and neck squamous cell carcinoma (HNSCC) patients is a common and adverse event associated with poor prognosis. Understanding the molecular mechanisms that mediate HNSCC metastasis may enable identification of novel therapeutic targets. E-cadherin plays a key role in epithelial intercellular adhesion; its downregulation is a hallmark of the epithelial-to-mesenchymal transition (EMT) (an essential process during tumor progression); and it is associated with invasion, metastasis, and decreased survival. Inflammatory cytokines have been implicated in the progression of HNSCC. Herein, the mechanisms by which the inflammatory mediator, Interleukin-1β (IL-1β), might contribute to EMT in HNSCC is investigated. The pathways involved in E-cadherin regulation in HNSCC had not previously been defined. It is hypothesized that 1) inflammatory mediators upregulate cyclooxygenase-2/prostaglandin E2 (COX-2/PGE2), which then in turn regulate E-cadherin expression in HNSCC; and 2) PGE2 downregulates E-cadherin via transcriptional repressors of E-cadherin (such as Snail) in HNSCC. The outcome of the proposed research will allow us to define how resistance to epidermal growth factor receptor (EGFR)-selective tyrosine kinase inhibitors is mediated and whether the benefits of combination therapy are due to the capacity of COX-2 inhibitors to increase E-cadherin expression and thus create a more sensitive target for EGFR TK inhibition. STUDY DESIGN Basic science, molecular biology, animal model, immunohistochemistry. METHODS We evaluated the effect of IL-1β on the molecular events of EMT in surgical specimens and HNSCC cell lines. We examined the correlation with tumor histologic features, and a severely compromised immunodeficient (SCID) xenograft model was used to assess the effects in vivo. RESULTS COX-2-dependent pathways contribute to the modulation of E-cadherin expression in HNSCC. An inverse relationship between COX-2 and E-cadherin was demonstrated in situ by double immunohistochemical staining of human HNSCC tissue sections. Treatment of HNSCC cells with IL-1β caused the downregulation of E-cadherin expression and upregulation of COX-2 expression. This effect was blocked in the presence of COX-2 small hairpin RNA (shRNA). IL-1β -treated HNSCC cell lines demonstrated a significant decrease in E-cadherin messenger RNA (mRNA) and an increase in the mRNA expression of the transcriptional repressor Snail. IL-1β exposure led to enhanced Snail binding at the chromatin level. ShRNA-mediated knockdown of Snail interrupted the capacity of IL-1β to downregulate E-cadherin. Snail overexpression in normal oral keratinocytes and HNSCC cells is sufficient to drive EMT and confers resistance to erlotinib. In a SCID xenograft model, HNSCC Snail overexpressing cells demonstrated significantly increased primary and metastatic tumor burdens. CONCLUSIONS The inflammatory mediator IL-1β modulates Snail and thereby regulates COX-2-dependent E-cadherin expression in HNSCC. This is the first report indicating the role of Snail in the inflammation-induced promotion of EMT in HNSCC. This newly defined pathway for transcriptional regulation of E-cadherin in HNSCC has important implications for targeted chemoprevention and therapy. LEVEL OF EVIDENCE N/A.

Abstract
Novel treatment options are needed for the successful therapy of patients with high-risk neuroblastoma. Here, we investigated the cyclin-dependent kinase (CDK) inhibitor SNS-032 in a panel of 109 neuroblastoma cell lines consisting of 19 parental cell lines and 90 sublines with acquired resistance to 14 different anticancer drugs. Seventy-three percent of the investigated neuroblastoma cell lines and all four investigated primary tumor samples displayed concentrations that reduce cell viability by 50% in the range of the therapeutic plasma levels reported for SNS-032 (<754 nM). Sixty-two percent of the cell lines and two of the primary samples displayed concentrations that reduce cell viability by 90% in this concentration range. SNS-032 also impaired the growth of the multidrug-resistant cisplatin-adapted UKF-NB-3 subline UKF-NB-3(r)CDDP(1000) in mice. ABCB1 expression (but not ABCG2 expression) conferred resistance to SNS-032. The antineuroblastoma effects of SNS-032 did not depend on functional p53. The antineuroblastoma mechanism of SNS-032 included CDK7 and CDK9 inhibition-mediated suppression of RNA synthesis and subsequent depletion of antiapoptotic proteins with a fast turnover rate including X-linked inhibitor of apoptosis (XIAP), myeloid cell leukemia sequence 1 (Mcl-1), baculoviral IAP repeat containing 2 (BIRC2; cIAP-1), and survivin. In conclusion, CDK7 and CDK9 represent promising drug targets and SNS-032 represents a potential treatment option for neuroblastoma including therapy-refractory cases.

Abstract
Esophageal cancer (EC) is one of the most aggressive gastrointestinal malignancies, possessing an insidious onset and a poor prognosis. Numerous transcription factors and inflammatory mediators have been reported to play a pivotal role in the initiation and progression of this cancer. However, the specifics of the signaling network responsible for said factors, especially which elements are the critical regulators, are still being elucidated. Glycogen synthesis kinases 3 (GSK3)β was originally regarded as a kinase regulating glucose metabolism. Accumulating evidence demonstrated that it also played an essential role in a variety of cellular processes including proliferation, differentiation, inflammation, motility, and survival by regulating various transcription factors such as c-Jun, AP-1, β-catenin, CREB, and NF-κB. Aberrant regulation of GSK3β has been shown to promote cell growth in some cancers, while suppressing it in others, and thus may play an important role in the development of EC. This review will discuss our current understanding of GSK3β signaling, and its control of the expression and activation of various transcription factors that mediate the inflammatory response. We will also explore some of the known mediators of EC progression, and based on current literature, elucidate the potential roles and implications of GSK3 in this disease.

Abstract
In this study, we investigated whether single nucleotide polymorphisms (SNPs) of the interleukin-1 beta (IL-1B) were associated with papillary thyroid carcinoma (PTC). We also assessed the relationships between IL-1B SNPs and the clinicopathologic characteristics of PTC patients. Ninety-three PTC patients and 324 controls were recruited. The patients with PTC were dichotomized and compared with respect to the clinicopathologic characteristics of PTC. Seven SNPs in the IL-1B gene were selected and genotyped using direct sequencing. Four SNPs (rs1143627, rs3136558, rs1143633, and rs1143643) in the IL-1B gene were significantly associated with PTC (p < 0.05). In clinicopathologic features, 3 SNPs (rs1143630, rs1143633, and rs1143643) showed a strong relationship with lymph node metastasis of PTC. The genotype and allele frequencies of rs1143630 and rs1143643 remained significantly associated with lymph node metastasis after Bonferroni correction for multiple testing. In haplotype analysis, two linkage disequilibrium blocks (block 1 consisted of rs1143627, rs3917356, and rs1143630; block 2 consisted of rs1143633 and rs1143643) also revealed significant associations with lymph node metastasis. Our results suggest that IL-1B polymorphisms may be associated with the risk of PTC in the Korean population. Especially, IL-1B polymorphisms might be a predictive factor for lymph node metastasis of PTC patients.

Abstract
Despite a large number of studies indicating that celecoxib plays an important role in the prevention and treatment of tumors, the detailed molecular mechanisms are not well understood. The aim of the present study was to investigate the effect of celecoxib on insulin-like growth factor 1 (IGF-1)-induced growth and invasion in non-small cell lung cancer (NSCLC). For these experiments, IGF-1-induced cell growth and invasion were analyzed in A549 cells in the presence and absence of celecoxib. The effects of celecoxib on the expression of phosphorylated type-1 IGF receptor (IGF-1R) and phosphorylated AKT (p-AKT) were examined using western blot analysis. The influence of celecoxib on IGF-binding protein-3 (IGFBP-3) expression was analyzed using ELISA. Celecoxib inhibited IGF-1-stimulated growth and invasion in a dose-dependent manner. Celecoxib also reduced the expression of IGF-1R, IGFBP-3 and phosphorylation of AKT. The results suggest that modulating the IGF axis may be a new mechanism for the anticancer effect of celecoxib on NSCLC.

Abstract
OBJECTIVE Previous studies have shown Snail expression integral to the epithelial-mesenchymal transition during tumor progression. However, its behavior in clinical head and neck squamous cell carcinomas (HNSCCs) is yet undefined. We therefore sought to (1) investigate clinical and histopathologic characteristics of Snail-positive HNSCC and (2) understand the link between Snail and other commonly used HNSCC tumor markers. STUDY DESIGN A retrospective case-control study was conducted. SETTING This study was conducted in a large-scale academic center. STUDY SUBJECTS Of 51 consecutive HNSCC, 42 surgical resections were included. METHODS Two separate pathologists performed standard histopathologic reviews along with immunohistochemistries (Snail, E-cadherin, p16, epidermal growth factor receptor [EGFR]) and in situ hybridization (human papilloma virus [HPV]). Medical review for all cases was performed. RESULTS Twenty-two (52%) of 42 cases stained 4+ Snail (>75% staining). The remaining 20 cases were considered negative. Snail was strongly inversely related to E-cadherin expression (ρ = -0.69, P < .001), but statistically independent from HPV, p16, or EGFR expression. Snail(+) tumors were equally represented from each anatomic subsite. Snail(+) tumors were strongly associated with poor differentiation (P < .001) and basaloid classification (P = .004). Snail(+) tumors were also strongly associated with lymphovascular invasion (P = .02), but not perineural invasion. Ultimately, 11 (50%) of 22 of Snail(+) tumors demonstrated positive nodal metastasis and 11 (79%) of 14 node-positive cases were Snail(+) (P = .02). CONCLUSION This pilot study provides promising evidence of Snail' role as a molecular prognostic marker for HNSCC. Snail positivity is significantly predictive of poorly differentiated, lymphovascular invasive, as well as regionally metastatic tumors. Because Snail positivity appears independent of HPV, p16, and EGFR expression, Snail may prove to improve upon these markers' predictive limitations.

Abstract
Interleukin (IL)-1 beta has been reported to be a marker of shorter survival in gastric and colorectal adenocarcinoma. In the present study, we examined the potential role and prognostic value of IL-1 beta in esophageal squamous cell carcinoma (SCC). Human esophageal SCC cell line, CE81T, was selected for cellular and animal experiments, in which biological changes after experimental manipulation of IL-1 beta signaling were explored, including tumor growth, invasion capacity, and the sensitivity to treatment. Moreover, 147 esophageal SCC samples were analyzed using immunohistochemical staining to correlate the expression of IL-1 beta with clinical outcome. Our data revealed that IL-1 beta was significantly overexpressed both at mRNA and protein levels in cancer specimens compared to nonmalignant tissues. When IL-1 beta signaling was blocked, tumor growth, invasion ability, and treatment resistance were attenuated. Activation of NF-kappa B, increase of E2-EPF ubiquitin carrier protein and subsequent epithelial-mesenchymal transition might be the underlying mechanisms of the more aggressive tumor growth in IL-1 beta-positive esophageal cancer. The immunochemistry findings indicate that positivity staining of IL-1 beta correlated significantly with higher clinical stage, lower response rate to concurrent chemoradiotherapy (CCRT), and higher recurrence rate after curative treatment. Moreover, IL-1 beta was a significant predictor of survival in patients undergoing surgical intervention or definite CCRT. In conclusion, IL-1 beta is significantly linked to poor prognosis for patients with esophageal cancer and may be a promising molecular target for therapeutic intervention for esophageal SCC.

Abstract
Increasing evidence suggests that the tumor microenvironment plays an important role in tumor progression and oncogenesis. Various proinflammatory mediators contribute to tumor proliferation, neoangiogenesis, invasion, metastasis, and resistance to cancer therapy such as hormonal therapy and chemotherapy. The major causes of death related to head and neck squamous cell carcinoma (HNSCC) include cervical node and distant metastases. Epithelial-mesenchymal transition (EMT) has been identified to play a key role in mediating the tumor invasion and metastasis of carcinomas. Herein, the relationship between proinflammatory mediators and EMT in HNSCC was investigated. Immunohistochemical expression of interleukin-1 β (IL-1β), cyclooxygenase-2 (COX-2), Slug and E-cadherin in relationship to histologic differentiation, clinical stage and nodal status was evaluated in 146 surgical specimens of HNSCC. A correlation was noted between increased expression of IL-1β and nodal status, as well as increased expression of COX-2 and histologic differentiation, clinical stage and nodal status. Increased Slug expression was correlated with histologic differentiation and clinical stage. Decreased E-cadherin expression was correlated with histologic differentiation and nodal status. A significant relationship was observed between IL-1β and COX-2. However, a significant inverse correlation was noted between Slug and E-cadherin. A significant relationship was observed between increased proinflammatory mediator IL-1β/COX-2 expression and increased EMT marker Slug/E-cadherin expression. These results indicate that proinflammatory mediators IL-1β and COX-2 may induce EMT through an increase in Slug and a decrease in E-cadherin. The present findings suggest that various anti-inflammatory agents could be used as an adjuvant treatment modality with anti-cancer chemotherapeutic drugs in HNSCC.

Abstract
CXCL12 is considered a constitutively expressed chemokine with homeostatic functions. However, induction of CXCL12 expression and its potential role in several pathologic conditions have been reported, suggesting that CXCL12 gene expression can be induced by different stimuli. To elucidate the molecular mechanisms involved in the regulation of CXCL12 gene expression, we aim to define the molecular factors that operate at the transcriptional level. Basal, constitutive expression of CXCL12 was dependent on basic helix-loop-helix factors. Transcriptional up-regulation of the CXCL12 gene was induced by cellular confluence or inflammatory stimuli such as interleukin-1 and interleukin-6, in a CCAAT/enhancer binding protein beta (c/EBPbeta)-dependent manner. Chromatin immunoprecipitation assays confirmed c/EBPbeta binding to a specific response element located at -1171 of the promoter region of CXCL12. Our data show that c/EBPbeta is a major regulatory element driving transcription of the CXCL12 gene in response to cytokines and cell confluence.

Abstract
PURPOSE Inflammatory cytokines have been implicated in the progression of head and neck squamous cell carcinoma (HNSCC). Herein we investigate the mechanisms by which interleukin-1beta (IL-1beta) might contribute to Epithelial-Mesenchymal Transition (EMT) in HNSCC. EXPERIMENTAL DESIGN We evaluated the effect of IL-1beta on the molecular events of EMT in surgical specimens and HNSCC cell lines. We examined the correlation with tumor histologic features, and a SCID xenograft model was used to assess the effects of Snail overexpression. RESULTS Cyclooxygenase-2 (COX-2)-dependent pathways contribute to the modulation of E-cadherin expression in HNSCC. An inverse relationship between COX-2 and E-cadherin was shown in situ by double immunohistochemical staining of human HNSCC tissue sections. Treatment of HNSCC cells with IL-1beta caused the downregulation of E-cadherin expression and upregulation of COX-2 expression. This effect was blocked in the presence of COX-2 small hairpin RNA. IL-1beta-treated HNSCC cell lines showed a significant decrease in E-cadherin mRNA and an increase in the mRNA expression of the transcriptional repressor Snail. IL-1beta exposure led to enhanced Snail binding at the chromatin level. Small hairpin RNA-mediated knockdown of Snail interrupted the capacity of IL-1beta to downregulate E-cadherin. In a SCID xenograft model, HNSCC Snail-overexpressing cells showed significantly increased primary and metastatic tumor burdens. CONCLUSIONS IL-1beta modulates Snail and thereby regulates COX-2-dependent E-cadherin expression in HNSCC. This is the first report indicating the role of Snail in the inflammation-induced promotion of EMT in HNSCC. This newly defined pathway for transcriptional regulation of E-cadherin in HNSCC has important implications for targeted chemoprevention and therapy.

Abstract
Cdk2 was once believed to play an essential role in cell cycle progression, but cdk2(-/-) mice have minimal phenotypic abnormalities. In this study, we examined the role of cdk2 in hepatocyte proliferation, centrosome duplication and survival. Cdk2(-/-) hepatocytes underwent mitosis and had normal centrosome content after mitogen stimulation. Unlike wild-type cells, cdk2(-/-) liver cells failed to undergo centrosome overduplication in response to ectopic cyclin D1 expression. After mitogen stimulation in culture or partial hepatectomy in vivo, cdk2(-/-) hepatocytes demonstrated diminished proliferation. Cyclin D1 is a key mediator of cell cycle progression in hepatocytes, and transient expression of this protein is sufficient to promote robust proliferation of these cells in vivo. In cdk2(-/-) mice and animals treated with the cdk2 inhibitor seliciclib, cyclin D1 failed to induce hepatocyte cell cycle progression. Surprisingly, cdk2 ablation or inhibition led to massive hepatocyte and animal death following cyclin D1 transfection. In a transgenic model of chronic hepatic cyclin D1 expression, seliciclib induced hepatocyte injury and animal death, suggesting that cdk2 is required for survival of cyclin D1-expressing cells even in the absence of substantial proliferation. In conclusion, our studies demonstrate that cdk2 plays a role in liver regeneration. Furthermore, it is essential for centrosome overduplication, proliferation and survival of hepatocytes that aberrantly express cyclin D1 in vivo. These studies suggest that cdk2 may warrant further investigation as a target for therapy of liver tumors with constitutive cyclin D1 expression.

Abstract
Ricin is a potent ribotoxin considered to be a potentially dangerous bioterrorist agent due to its wide availability and the possibility of aerosol delivery to human populations. Studies in rodents and nonhuman primates have demonstrated that ricin delivered to the pulmonary system leads to acute lung injury and symptoms resembling acute respiratory distress syndrome. Increasing evidence suggests that the inflammatory effects triggered by ricin are responsible for its lethality. We demonstrated previously that ricin administered to the lungs of mice causes death of pulmonary macrophages and the release of proinflammatory cytokines, suggesting macrophages may be a primary target of ricin. Here we examined the requirement for macrophages in the development of ricin-mediated pulmonary inflammation by employing transgenic (MAFIA) mice that express an inducible gene driven by the c-fms promoter for Fas-mediated apoptosis of macrophages upon injection of a synthetic dimerizer, AP20187. Administration of aerosolized ricin to macrophage-depleted mice led to reduced inflammatory responses, including recruitment of neutrophils, expression of proinflammatory transcripts, and microvascular permeability. When compared with control mice treated with ricin, macrophage-depleted mice treated with ricin displayed a reduction in pulmonary IL-1beta. Employing mice deficient in IL-1, we found that ricin-induced inflammatory responses were suppressed, including neutrophilia. Neutrophilia could be restored by co-administering ricin and exogenous IL-1beta to IL-1alpha/beta(-/-) mice. Furthermore, IL1Ra/anakinra cotreatment inhibited ricin-mediated inflammatory responses, including recruitment of neutrophils, expression of proinflammatory genes, and histopathology. These data suggest a central role for macrophages and IL-1 signaling in the inflammatory process triggered by ricin.

Abstract
Cell proliferation, migration, and capillary network formation of endothelial cells are the fundamental steps for angiogenesis, which involves the formation of new blood vessels. The purpose of this study is to investigate the effect of a novel aminothiazole SNS-032 on these critical steps for in vitro angiogenesis using a coculture system consisting of human umbilical vein endothelial cells (HUVECs) and human glioblastoma cells (U87MG). SNS-032 is a potent selective inhibitor of cyclin-dependent kinases 2, 7, and 9, and inhibits both transcription and cell cycle. In this study, we examined the proliferation and viability of HUVECs and U87MG cells in the presence of SNS-032 and observed a dose-dependent inhibition of cellular proliferation in both cell lines. SNS-032 inhibited threedimensional capillary network formations of endothelial cells. In a coculture study, SNS-032 completely prevented U87MG cell-mediated capillary formation of HUVECs. This inhibitor also prevented the migration of HUVECs when cultured alone or cocultured with U87MG cells. In addition, SNS-032 significantly prevented the production of vascular endothelial growth factor (VEGF) in both cell lines, whereas SNS-032 was less effective in preventing capillary network formation and migration of endothelial cells when an active recombinant VEGF was added to the medium. In conclusion, SNS-032 prevents in vitro angiogenesis, and this action is attributable to blocking of VEGF.
