Exploring extracellular matrix and prostaglandin pathway alterations across varying resection margin distances of right-sided colonic adenocarcinoma. BMC Cancer 2023; 23:1202.

Abstract
BACKGROUND Surgical resection followed by indicated adjuvant therapy offers potential curative treatment in colonic adenocarcinoma. Beyond the well-established seed and soil theory of colon cancer progression, the 'normal-appearing' tissues near the tumor are not genuinely normal and remain as remnants in patients following surgery. Our objective was to elucidate the alteration of gene expression and pathways across various distances of resection margins in right-sided colonic adenocarcinoma. METHODS Twenty-seven fresh samples of primary cancer and 56 matched non-tumor tissues adjacent to the tumor (NAT) were collected from patients with resectable right-sided colon cancer. NAT were systematically obtained at varying distances (1, 5, and 10 cm) on both proximal and distal sides. Comprehensive gene expression analysis was performed using 770-gene PanCancer Progression Panel, delineating distinctive pathways and functional predictions for each region. RESULTS Distinctive gene signatures and pathways exhibited by normal-appearing tissues were discovered at varying distances from cancer. Notably, SFRP2, PTGDS, COL1A1, IL1B, THBS2, PTGIS, COL1A2, NPR1, and BGN were upregulated, while ENPEP, MMP1, and NRCAM were downregulated significantly in 1-cm tissue compared to farther distances. Substantial alterations in the extracellular matrix (ECM) and prostaglandin/thromboxane synthesis were significantly evident at the 1-cm distance. Functional analysis indicated enhanced cell viability and survival, alongside reduced cellular death and apoptosis. CONCLUSIONS Different distances exerted a significant impact on gene alteration within the normal-looking mucosa surrounding primary cancer, influenced by various mechanisms. These findings may highlight potential therapeutic targets related to the ECM and prostaglandin/thromboxane pathways for treatment strategies.

Abstract
The renin-angiotensin-aldosterone system (RAAS), is an old system with new fundamental roles in cancer biology which influences cell growth, migration, death, and metastasis. RAAS signaling enhances cell proliferation in malignancy directly and indirectly by affecting tumor cells and modulating angiogenesis. Cancer development may be influenced by the balance between the ACE/Ang II/AT1R and the ACE2/Ang 1-7/Mas receptor pathways. The interactions between Ang II/AT1R and Ang I/AT2R as well as Ang1-7/Mas and alamandine/MrgD receptors in the RAAS pathway can significantly impact the development of cancer. Ang I/AT2R, Ang1-7/Mas, and alamandine/MrgD interactions can have anticancer effects while Ang II/AT1R interactions can be involved in the development of cancer. Evidence suggests that inhibitors of the RAAS, which are conventionally used to treat cardiovascular diseases, may be beneficial in cancer therapies.Herein, we aim to provide a thorough description of the elements of RAAS and their molecular play in cancer. Alongside this, the role of RAAS components in sex-dependent cancers as well as GI cancers will be discussed with the hope of enlightening new venues for adjuvant cancer treatment.

Abstract
Regulatory regions in the human genome, enriched in guanine-rich DNA sequences have a remarkable enrichment of G-rich sequences having a tendency to fold into G-quadruplex structures. To identify the G-quadruplex forming motifs in regulatory regions of stem cell markers, gene sequences of various stem cell markers were downloaded and analyzed to see the abundance of G-rich sequences. We observed the enrichment of G-rich sequences in stem cell markers (CD13, CD19, CD24 and CD38) which could possibly play a critical role in its regulation. We used Circular Dichroism (CD), UV-Thermal denaturation (UV-Tm) and polyacrylamide gel electrophoresis (PAGE) to demonstrate the formation of a G-quadruplex by G-rich sequences present in these stem cell markers. We observed that these G-rich sequences containing minimum consecutive G3 stretch separated by loop length ranging from one to three bases long adopt G-quadruplexes with different molecularity involving two-strands, three-strand and four-strand with parallel and antiparallel conformation. Interestingly, we proposed the formation of three-stranded G-quadruplex by CD13 in 100 mM Na+, CD19 in 100 mM K+, 100 mM K+ with 40 wt% PEG 200, and CD38 in 100 mM K+ + 40 wt% PEG 200. The formation of such diverse G-quadruplex structures in the regulatory regions leaves the fair possibility of recognition by regulatory factors to modulate the gene expression. First time, this study may give insight into the structural polymorphism of G4 forming motifs in different stem cell markers to design the best suitable ligand and to target them for therapeutic development.Communicated by Ramaswamy H.

Abstract
Abstract
Cancer is the second leading cause of death worldwide. Peptidases participate in tumor development and growth. Mammalian neutral aminopeptidase (APN, EC 3.4.11.2, M1 family) catalyzes the cleavage of neutral and basic amino acids from the N-terminus of substrates. APN expression is dysregulated in several types of cancer, being a target for the development of new anticancer agents. Recently, we identified three new non-competitive inhibitors of soluble porcine APN (pAPN) by virtual screening (BTB11079, JFD00064, BTB07018, from Maybridge). In the present contribution we assayed their effect on the activity of APN in a microsomal preparation of porcine kidney cortex, a model of the physicochemical environment of the enzyme. These classical inhibitors had an IC50 value of 3–5 µM. Additionally, using a kinetic approach and a specific substrate, we quantified APN activity on the cell surface of human and murine lung, colon, prostate, and skin tumor cells. APN inhibitors reduced tumor cells viability, more efficiently in the higher APN activity tumor cell lines, but not in non-tumoral cells. BTB11079, JFD00064, BTB07018 effects on cell viability were stronger than that of bestatin, a positive control. Thus, these non-competitive APN inhibitors may be useful tools for cancer treatment.

Abstract
INTRODUCTION The renin angiotensin system (RAS) is emerging as an important target for the treatment of glioma. We had described that the local RAS is involved in vivo in tumor growth in the rat model of experimental C6 glioma implanted at the subcutaneous region, through the modification of several proteolytic regulatory enzymes of aminopeptidase type. METHODS We analyze RAS-regulating aminopeptidase activities in plasma and brain tissue of control male and female rats and rats with transplacental ethylnitrosourea-induced gliomas. RESULTS No differences were found either the mean total number of tumors per animal or the tumor volume between male and female animals. However, we have found increased levels in aspartyl aminopeptidase in both males and females and of aminopeptidase B only in males. On the contrary, decreased levels were found in aminopeptidase N and insulin-regulated aminopeptidase activities in both males and females, whereas aminopeptidase A only decreased in females. Decreased levels of aminopeptidase N, aminopeptidase B and insulin-regulated aminopeptidase were also shown in plasma of only female rats. CONCLUSIONS Under the complexity of RAS cascade, the changes found suggest the predominant actions of angiotensin III against a decreased action of angiotensin II and angiotensin IV. We conclude that angiotensin peptides are involved in tumor growth in this rat model of glioma and that their role in tumor growth can be analyzed through their corresponding proteolytic regulatory enzymes, which make them new and attractive therapeutic targets beyond the use or angiotensin converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs).

The Impact of Ang-(1-9) and Ang-(3-7) on the Biological Properties of Prostate Cancer Cells by Modulation of Inflammatory and Steroidogenesis Pathway Genes. Int J Mol Sci 2020; 21:ijms21176227.

Abstract
The local renin–angiotensin system (RAS) plays an important role in the pathophysiology of the prostate, including cancer development and progression. The Ang-(1-9) and Ang-(3-7) are the less known active peptides of RAS. This study examines the influence of these two peptide hormones on the metabolic activity, proliferation and migration of prostate cancer cells. Significant changes in MTT dye reduction were observed depending on the type of angiotensin and its concentration as well as time of incubation. Ang-(1-9) did not regulate the 2D cell division of either prostate cancer lines however, it reduced the size of LNCaP colonies formed in soft agar, maybe through down-regulation of the HIF1a gene. Ang-(3-7) increased the number of PC3 cells in the S phase and improved anchorage-independent growth as well as mobility. In this case, a significant increase in MKI67, BIRC5, and CDH-1 gene expression was also observed as well as all members of the NF-kB family. Furthermore, we speculate that this peptide can repress the proliferation of LNCaP cells by NOS3-mediated G2/M cell cycle arrest. No changes in expression of BIRC5 and BCL2/BAX ratio were observed but a decrease mRNA proapoptotic BAD gene was seen. In the both lines, Ang-(3-7) improved ROCK1 gene expression however, increased VEGF and NOS3 mRNA was only seen in the PC3 or LNCaP cells, respectively. Interestingly, it appears that Ang-(1-9) and Ang-(3-7) can modulate the level of steroidogenic enzymes responsible for converting cholesterol to testosterone in both prostate cancer lines. Furthermore, in PC3 cells, Ang-(1-9) upregulated AR expression while Ang-(3-7) upregulated the expression of both estrogen receptor genes. Ang-(1-9) and Ang-(3-7) can impact on biological properties of prostate cancer cells by modulating inflammatory and steroidogenesis pathway genes, among others.

Abstract
There is growing evidence that renin-angiotensin system (RAS) components have been involved in the development of various types of cancers, including prostate cancer. This article for the first time reports the impact of Ang1-9 and Ang3-7 on viability and proliferation, migration and invasion of epithelial prostate cells. The results of this study clearly show that Ang1-9 and Ang3-7 exert different/opposite effects on in vitro biological properties of prostate cells. It appears that Ang1-9 has pro-cancer activities via the ability to induce cell divisions, enhance cell motility and stimulate the expression of such genes as vascular endothelial growth factor (VEGF), hypoxia-inducible factors (HIF-1), vimentin (VIM) and REL proto-oncogene, NF-kB subunit (REL). On the contrary, Ang3-7 did not show any mitogenic activity. Furthermore, this peptide hormone limited the migration of PNT1A cells probably by downregulation of VEGF and VIM expression. Finally, it is worth noting that both angiotensins have the ability to modulate gene expression for angiotensin receptors. Unfortunately, we could not unequivocally identify the type of angiotensin receptor responsible for signal transduction pathway involved in PNT1A cell survival and proliferation. Undoubtedly, further research and testing in this area are necessary.

CNS & NEUROLOGICAL DISORDERS-DRUG TARGETS 2019; 18:29-36. [DOI: 10.2174/1871527317666181029111739] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/05/2018] [Revised: 07/13/2018] [Accepted: 10/10/2018] [Indexed: 11/22/2022]
Abstract
Background:
It has been described that doxazosin, an antihypertensive drug, also promotes
glioblastoma cells death by inhibiting cell proliferation, arresting cell cycle and inducing apoptosis.
Doxazosin has also demonstrated several modulator effects on renin-angiotensin system (RAS)-
regulating aminopeptidase activities, which are highly involved in tumor growth in experimental
glioma. Therefore, it remains to elucidate if the anti-tumoral effects of doxazosin could also be mediated
by the proteolytic regulatory components of the RAS.
Objective:
To analyze the effects of doxazosin on cell growth and on RAS-regulating proteolytic regulatory
aspartyl aminopeptidase (ASAP), aminopeptidase A (APA), aminopeptidase N (APN), aminopeptidase
B (APB) and insulin-regulated aminopeptidase (IRAP) specific activities in the human neuroblastoma
NB69 and astroglioma U373-MG tumoral cell lines.
Methods:
Human neuroblastoma NB69 and astroglioma U373-MG cell lines were treated with doxazosin
50-500 μM for 24h or 48h. The effects on cell growth and on RAS-regulating aminopeptidase
specific activities were analyzed.
Results:
Doxazosin treatments promote a concentration-dependent inhibition on cell growth in both
NB69 and U373-MG cells, being NB69 cells more sensitive to the drug than U373-MG cells. However,
its effects on RAS-regulating aminopeptidase specific activities depend on the concentration
used, the duration of the treatment and the cell type. These data confirm the existence of a different
dynamic progression of RAS cascade in each tumoral cell line as a consequence of the treatment with
doxazosin and time of action, which also implies a very dynamic metabolism of the peptides which
participate in each step of RAS cascade.
Conclusion:
Our results indicate that doxazosin modifies the proteolytic regulatory enzymes of RAS
cascade, modulating the bioactive efficacy of the different angiotensin peptides, and therefore, of their
functional roles as initiators/promoters of cell proliferation as autocrine/paracrine mediators.

Abstract
We recently reported that angiotensin II receptor blockers (ARBs) have chemopreventive and chemotherapeutic potential against prostate cancer via the reduction of androgen receptor (AR) expression. In this study, we investigated the effects of the angiotensin II receptor type 2 (AT2R) agonist Compound 21 (C21), which is expected to play similar roles to an ARB, on prostate carcinogenesis using the transgenic rat for adenocarcinoma of prostate (TRAP) model previously established in our laboratory. In vitro analyses of the cell growth, Western blotting and reporter gene assays were performed using LNCaP cells. TRAP rats at 6 weeks of age were randomly divided into 3 groups of 12 animals each and treated with C21 at 1 or 2 mg/kg/day in drinking water for 12 weeks. C21 reduced the proliferation activity of prostate cancer cells and down-regulated the PSA promoter activity and the AR protein expression. We discovered that C21 inhibited the progression of prostate carcinogenesis in TRAP rats and decreased the incidence of adenocarcinoma in the lateral prostate. A significant increase in the apoptotic index with activation of caspase 3 and 7 were observed by immunohistochemistry and Western blotting analyses. C21 also down-regulated the expression of AR significantly in TRAP rat prostate. C21 decreased the expression of AR and reduced the proliferation activity effectively in prostate cancer cells and TRAP rat prostate. These findings suggest that AT2R agonist may be a candidate novel chemopreventive agent against human prostate cancer.

Chuang HY, Jiang JK, Yang MH, Wang HW, Li MC, Tsai CY, Jhang YY, Huang JC. Aminopeptidase A initiates tumorigenesis and enhances tumor cell stemness via TWIST1 upregulation in colorectal cancer. Oncotarget 2017; 8:21266-21280. [PMID: 28177885 PMCID: PMC5400582 DOI: 10.18632/oncotarget.15072] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2016] [Accepted: 01/11/2017] [Indexed: 01/12/2023] Open
Abstract
Metastasis accounts for the high mortality rate associated with colorectal cancer (CRC), but metastasis regulators are not fully understood. To identify a novel gene involved in tumor metastasis, we used oligonucleotide microarrays, transcriptome distance analyses, and machine learning algorithms to determine links between primary and metastatic colorectal cancers. Aminopeptidase A (APA; also known as ENPEP) was selected as our focus because its relationship with colorectal cancer requires clarification. Higher APA mRNA levels were observed in patients in advanced stages of cancer, suggesting a correlation between ENPEP and degree of malignancy. Our data also indicate that APA overexpression in CRC cells induced cell migration, invasion, anchorage-independent capability, and mesenchyme-like characteristics (e.g., EMT markers). We also observed TWIST induction in APA-overexpressing SW480 cells and TWIST down-regulation in HT29 cells knocked down with APA. Both APA silencing and impaired APA activity were found to reduce migratory capacity, cancer anchorage, stemness properties, and drug resistance in vitro and in vivo. We therefore suggest that APA enzymatic activity affects tumor initiation and cancer malignancy in a TWIST-dependent manner. Results from RT-qPCR and the immunohistochemical staining of specimens taken from CRC patients indicate a significant correlation between APA and TWIST. According to data from SurvExpress analyses of TWIST1 and APA mRNA expression profiles, high APA and TWIST expression are positively correlated with poor CRC prognosis. APA may act as a prognostic factor and/or therapeutic target for CRC metastasis and recurrence.

Abstract
Near-infrared fluorescence (NIRF) imaging is an emerging imaging technique for studying diseases at the molecular level. Optical imaging with a near-infrared emitting fluorophore for targeting tumor angiogenesis offers a noninvasive method for early tumor detection and efficient monitoring of tumor response to anti-angiogenesis therapy. CD13 receptor, a zinc-dependent membrane-bound ectopeptidase, plays important roles in regulating tumor angiogenesis and the growth of new blood vessels. In this chapter, we use CD13 receptor as an example to demonstrate how to construct CD13-specific NGR-containing peptides via bioorthogonal click chemistry for visualizing and quantifying the CD13 receptor expression in vivo by means of NIRF optical imaging.

Abstract
BACKGROUND Selecting a parsimonious set of informative genes to build highly generalized performance classifier is the most important task for the analysis of tumor microarray expression data. Many existing gene pair evaluation methods cannot highlight diverse patterns of gene pairs only used one strategy of vertical comparison and horizontal comparison, while individual-gene-ranking method ignores redundancy and synergy among genes. RESULTS Here we proposed a novel score measure named relative simplicity (RS). We evaluated gene pairs according to integrating vertical comparison with horizontal comparison, finally built RS-based direct classifier (RS-based DC) based on a set of informative genes capable of binary discrimination with a paired votes strategy. Nine multi-class gene expression datasets involving human cancers were used to validate the performance of new method. Compared with the nine reference models, RS-based DC received the highest average independent test accuracy (91.40%), the best generalization performance and the smallest informative average gene number (20.56). Compared with the four reference feature selection methods, RS also received the highest average test accuracy in three classifiers (Naïve Bayes, k-Nearest Neighbor and Support Vector Machine), and only RS can improve the performance of SVM. CONCLUSIONS Diverse patterns of gene pairs could be highlighted more fully while integrating vertical comparison with horizontal comparison strategy. DC core classifier can effectively control over-fitting. RS-based feature selection method combined with DC classifier can lead to more robust selection of informative genes and classification accuracy.

Abstract
Angiotensin II is a key biological peptide in the renin-angiotensin system that regulates blood pressure and renal hemodynamics, and extensive experimental studies have shown that angiotensin II promotes diverse fibrotic changes and induces neovascularization in several inflammatory diseases. It is known that angiotensin II can be controlled using renin-angiotensin system blockade when angiotensin II is the main factor inducing a particular disease, and renin-angiotensin system blockade has assumed a central role in the treatment of inflammatory nephritis, cardiovascular disorders and retinopathy. In contrast, renin-angiotensin system blockade was found to have not only these effects but also other functions, such as inhibition of cancer growth, angiogenesis and metastasis. Numerous studies have sought to elucidate the mechanisms and support these antitumor effects. However, a recent meta-analysis showed that renin-angiotensin system blockade use might in fact increase the incidence of cancer, so renin-angiotensin system blockade use has become somewhat controversial. Although the renin-angiotensin system has most certainly made great contributions to experimental models and clinical practice, some issues still need to be resolved. The present review discusses the contribution and controversy surrounding the renin-angiotensin system up to the present time.

Abstract
The reactions of [RhCl(CO)(PPh3)2], [RhCl(CO)2]2 and [IrCl(CO)(PPh3)2] with different 5-nitrosopyrimidines afforded sixteen complexes which have been structurally characterized by elemental analysis, IR and NMR ((1)H and (13)C) spectral methods and luminescence spectroscopy. The crystal and molecular structures of [Rh(III)Cl(VIOH-1)2(PPh3)], [Rh(III)Cl(DVIOH-1)2(PPh3)] and [Rh(II)(DVIOH-1)2(PPh3)2] have been established from single crystal x-ray structure analyses. The three complexes are six-coordinated with both violurato ligands into an equatorial N5,O4-bidentate fashion, but with different mutually arrangements. Theoretical studies were driven on the molecular structure of [Rh(III)Cl(VIOH-1)2(PPh3)] to assess the nature of the metal-ligand interaction as well as the foundations of the cis-trans (3L-2L) isomerism. An assortment of density functional (SOGGA11-X, B1LYP, B3LYP, B3LYP-D3 and wB97XD) has been used, all of them leading to a similar description of the target system. Thus, a topological analysis of the electronic density within AIM scheme and the study of the Mulliken charges yield a metal-ligand link of ionic character. Likewise, it has been proved that the cis-trans isomerism is mainly founded on that metal-ligand interaction with the relativistic effects playing a significant role. Although most of the compounds showed low direct toxicity against the human cell lines NB69 (neuroblastoma) and U373-MG (astroglioma), they differently modify in several ways the renin-angiotensin system (RAS)-regulating proteolytic regulatory enzymes aminopeptidase A (APA), aminopeptidase N (APN) and insulin-regulated aminopeptidase (IRAP). Therefore, these complexes could exert antitumor activity against both brain tumor types, acting through the paracrine regulating system mediated by tissue RAS rather than exerting a direct cytotoxic effect on tumor cells.

Abstract
CD13 receptor as a tumor vasculature biomarker has attracted great attention in cancer research. Through phage display screening, NGR-containing peptides have been characterized as specific ligands binding to CD13 receptor. In this study, a (64)Cu-labeled dimeric NGR peptide based on sarcophagine cage was synthesized and evaluated for micropositron emission tomography (PET) imaging of CD13 expression in vivo. Macrocyclic chelating agent (sarcophagine cage) was conjugated with two azide moieties, followed by mixing with an alkyne-containing NGR peptide to rapidly provide the Sar-NGR2 peptide by click chemistry. Radiolabeling of Sar-NGR2 with (64)Cu was achieved in >90% decay-corrected yield with radiochemical purity of >99%. The cell uptake study showed that (64)Cu-Sar-NGR2 binds to CD13-positive HT-1080 cells, but not to CD13-negative MCF-7 cells. MicroPET imaging results revealed that (64)Cu-Sar-NGR2 exhibits good tumor uptake in CD13-positive HT-1080 xenografts and significantly lower tumor uptake in CD13-negative MCF-7 xenografts. The CD13-specific binding of (64)Cu-Sar-NGR2 was further verified by significant reduction of tumor uptake in HT-1080 tumor xenografts with coinjection of a nonradiolabeled NGR peptide. The biodistribution results demonstrated good tumor/muscle ratio (8.28 ± 0.37) of (64)Cu-Sar-NGR2 at 24 h pi in HT-1080 tumor xenografts, which is in agreement with the quantitative analysis of microPET imaging. In conclusion, sarcophagine cage has been successfully applied to the construction of a (64)Cu-labeled dimeric NGR-containing peptide. In vitro and in vivo studies demonstrated that (64)Cu-Sar-NGR2 is a promising PET probe for imaging CD13 expression in living mice.

Abstract
GPCRs (G-protein-coupled receptors) are among the most important targets for drug discovery due to their ubiquitous expression and participation in cellular events under both healthy and disease conditions. These receptors can be activated by a plethora of ligands, such as ions, odorants, small ligands and peptides, including angiotensins and kinins, which are vasoactive peptides that are classically involved in the pathophysiology of cardiovascular events. These peptides and their corresponding GPCRs have been reported to play roles in other systems and under pathophysiological conditions, such as cancer, central nervous system disorders, metabolic dysfunction and bone resorption. More recently, new mechanisms have been described for the functional regulation of GPCRs, including the transactivation of other signal transduction receptors and the activation of G-protein-independent pathways. The existence of such alternative mechanisms for signal transduction and the discovery of agonists that can preferentially trigger one signalling pathway over other pathways (called biased agonists) have opened new perspectives for the discovery and development of drugs with a higher specificity of action and, therefore, fewer side effects. The present review summarizes the current knowledge on the non-canonical signalling and roles of angiotensins and kinins.

Abstract
Breast cancer is a leading cause of cancer-associated death worldwide. One of the most important prognostic factors for survival is the early detection of the disease. Recent studies indicate that extracellular vesicles may provide diagnostic information for cancer management. We demonstrate the secretion of extracellular vesicles by primary breast epithelial cells enriched for stem/progenitor cells cultured as mammospheres, in non-adherent conditions. Using a proteomic approach we identified proteins contained in these vesicles whose expression is affected by hormonal changes in the cellular environment. In addition, we showed that these vesicles are capable of promoting changes in expression levels of genes involved in epithelial-mesenchymal transition and stem cell markers. Our findings suggest that secreted extracellular vesicles could represent potential diagnostic and/or prognostic markers for breast cancer and support a role for extracellular vesicles in cancer progression.

Abstract
The NGR-containing peptides have been shown to bind specifically to CD13/aminopeptidase N (APN) receptor, one of the attractive tumor vasculature biomarkers. In this study, we evaluated (64)Cu-labeled monomeric and dimeric NGR peptides for microPET imaging of CD13 receptor expression in vivo. Western blot analysis and immunofluorescence staining were performed to identify CD13-positive and CD13-negative cell lines. NGR-containing peptides were conjugated with 1,4,7,10-tetraazadodecane-N,N',N″,N‴-tetraacetic acid (DOTA) and labeled with (64)Cu (t(1/2) = 12.7 h) in ammonium acetate buffer. The resulting monomeric ((64)Cu-DOTA-NGR1) and dimeric ((64)Cu-DOTA-NGR2) peptides were then subjected to in vitro stability, cell uptake and efflux, small animal micorPET, and biodistribution studies. In vitro studies demonstrated that CD13 receptors are overexpressed in human fibrosarcoma HT-1080 cells and negative in human colon adenocarcinoma HT-29 cells. The binding affinity of (64)Cu-DOTA-NGR2 to HT-1080 cells was measured to be within low nanomolar range and about 2-fold higher than that of (64)Cu-DOTA-NGR1. For small animal microPET studies, (64)Cu-DOTA-NGR2 displayed more favorable in vivo performance in terms of higher tumor uptake and slower tumor washout in CD13-positive HT-1080 tumor xenografts as compared to (64)Cu-DOTA-NGR1. As expected, significantly lower tumor uptake and poorer tumor/normal organ contrast were observed for both (64)Cu-DOTA-NGR1 and (64)Cu-DOTA-NGR2 in CD13-negative HT-29 tumor xenografts in comparison with those in the HT-1080 tumor xenografts. The CD13-specific tumor activity accumulation of both (64)Cu-DOTA-NGR1 and (64)Cu-DOTA-NGR2 was further demonstrated by significant reduction of tumor uptake in HT-1080 tumor xenografts with a coinjected blocking dose of cyclic NGR peptide [c(CNGRC)]. The biodistribution results were consistent with the quantitative analysis of microPET imaging. We concluded that both (64)Cu-DOTA-NGR1 and (64)Cu-DOTA-NGR2 have good and specific tumor uptake in CD13-positive HT-1080 tumor xenografts. (64)Cu-DOTA-NGR2 showed higher tumor uptake and better tumor retention than (64)Cu-DOTA-NGR1, presumably due to bivalency effect and increase in apparent molecular size. (64)Cu-DOTA-NGR2 is a promising PET probe for noninvasive detection of CD13 receptor expression in vivo.

Similarities and differences between effects of angiotensin III and angiotensin II on human prostate cancer cell migration and proliferation. Peptides 2012; 37:200-6.

Abstract
Proliferation plays a critical role in tumor growth when cell migration is essential to invasion. The effect of Ang III and Ang II was evaluated on these important processes. Changes in the migration potential of prostate cancer cells were investigated using Wound Healing Test and a Transwell Migration Chamber with a 3 μm pore size. Cell proliferation was measured with a BrdU Assay and Countess Automated Cell Counter, thus determining the influence of angiotensins on hormone-dependent (LNCaP) and hormone-independent (DU-145) human prostate cancer lines. The influence of Ang III and Ang II on classic receptors may be inhibited by Losartan or PD123319. Test peptide modulation of the AT1 and AT2 receptors was examined by Western Blot and fluorescent immunocytochemistry. The results indicate that Ang III promotes the migration of both LNCaP and DU-145 lines, whereas Ang II stimulates this process only in androgen-independent cells. Both angiotensin peptides can induce prostate cancer cell proliferation in a time- and dose-dependent manner. The obtained results show that Ang III and Ang II can modify the expression of classic receptors, particularly AT2. These results suggest that the investigated peptide can modulate cell migration and proliferation in prostate cancer cells. Angiotensins probably have a greater influence on proliferation in the early-stage prostate cancer model than hormone-independent cell lines. Assume also that Ang II can enhance the migration tendency aggressive prostate cancer cells, while Ang III does so more effective in non-metastatic cells.

Abstract
Processes that promote cancer progression such as angiogenesis require a functional interplay between malignant and nonmalignant cells in the tumor microenvironment. The metalloprotease aminopeptidase N (APN; CD13) is often overexpressed in tumor cells and has been implicated in angiogenesis and cancer progression. Our previous studies of APN-null mice revealed impaired neoangiogenesis in model systems without cancer cells and suggested the hypothesis that APN expressed by nonmalignant cells might promote tumor growth. We tested this hypothesis by comparing the effects of APN deficiency in allografted malignant (tumor) and nonmalignant (host) cells on tumor growth and metastasis in APN-null mice. In two independent tumor graft models, APN activity in both the tumors and the host cells cooperate to promote tumor vascularization and growth. Loss of APN expression by the host and/or the malignant cells also impaired lung metastasis in experimental mouse models. Thus, cooperation in APN expression by both cancer cells and nonmalignant stromal cells within the tumor microenvironment promotes angiogenesis, tumor growth, and metastasis.

Abstract
For cancers to develop, sustain and spread, the appropriation of key homeostatic physiological systems that influence cell growth, migration and death, as well as inflammation and the expansion of vascular networks are required. There is accumulating molecular and in vivo evidence to indicate that the expression and actions of the renin-angiotensin system (RAS) influence malignancy and also predict that RAS inhibitors, which are currently used to treat hypertension and cardiovascular disease, might augment cancer therapies. To appreciate this potential hegemony of the RAS in cancer, an expanded comprehension of the cellular actions of this system is needed, as well as a greater focus on translational and in vivo research.
