Abstract
Malignant neoplasms arising from the gastrointestinal (GI) tract are among the most common types of cancer with high mortality rates. Despite advances in treatment in a small subgroup harboring targetable mutations, the outcome remains poor, accounting for one in three cancer-related deaths observed globally. As a promising therapeutic option in various tumor types, immunotherapy with immune checkpoint inhibitors has also been evaluated in GI cancer, albeit with limited efficacy except for a small subgroup expressing microsatellite instability. In the quest for more effective treatment options, energetic efforts have been placed to evaluate the role of several immunotherapy approaches comprising of cancer vaccines, adoptive cell therapies and immune checkpoint inhibitors. In this review, we report our experience with a personalized dendritic cell cancer vaccine and cytokine-induced killer cell therapy in three patients with GI cancers and summarize current clinical data on combined immunotherapy strategies.

Abstract
Endogenous microRNAs (miRNA) in tumors are currently under exhaustive investigation as potential therapeutic agents for cancer treatment. Nevertheless, RNase degradation, inefficient and untargeted delivery, limited biological effect, and currently unclear side effects remain unsettled issues that frustrate clinical application. To address this, a versatile targeted delivery system for multiple therapeutic and diagnostic agents should be adapted for miRNA. In this study, we developed membrane-coated PLGA-b-PEG DC-chol nanoparticles (m-PPDCNPs) co-encapsulating doxorubicin (Dox) and miRNA-190-Cy7. Such a system showed low biotoxicity, high loading efficiency, and superior targeting ability. Systematic delivery of m-PPDCNPs in mouse models showed exceptionally specific tumor accumulation. Sustained release of miR-190 inhibited tumor angiogenesis, tumor growth, and migration by regulating a large group of angiogenic effectors. Moreover, m-PPDCNPs also enhanced the sensitivity of Dox by suppressing TGF-β signal in colorectal cancer cell lines and mouse models. Together, our results demonstrate a stimulating and promising m-PPDCNPs nanoplatform for colorectal cancer theranostics.

Abstract
Tumor vasculature blockade therapy (TVBT), including angiogenesis inhibition, vascular disruption, and vascular infarction, provides a promising treatment modality for solid tumors. However, low selectivity, drug resistance, and possible severe side effects have limited the clinical transformation of TVBT. Engineered nanoparticles offer potential solutions, including prolonged circulation time, targeted transportation, and controlled release of TVBT agents. Moreover, engineered nanomedicines provide a promising combination platform of TVBT with chemotherapy, radiotherapy, photodynamic therapy, photothermal therapy, ultrasound therapy, and gene therapy. In this article, we offer a comprehensive summary of the current progress of engineered nanomedicines for TVBT and also discuss current deficiencies and future directions for TVBT development. This article is categorized under: Therapeutic Approaches and Drug Discovery > Nanomedicine for Oncologic Disease Therapeutic Approaches and Drug Discovery > Emerging Technologies.

Abstract
Aim Cancer is one of the main causes of death worldwide. High mortality rates were reported among breast cancer patients which makes the development of new anticancer agents targeting breast cancer a priority. The synthesis of the compounds incorporating- N=N- group is an important field of research that may lead to the discovery of new anticancer drug. Materials and Methods In this work, we report the synthesis of a compound has O and N centers with the incorporation of the arylazo group (4-BrC6H4-N=N-) into acetylacetone to synthesize 3-(4-Bromo phenylazo)-2,4-pentanedione. Physical characteristics of the newly synthesized compound were determined by measuring electronic absorption spectra, nuclear magnetic resonances, and the infrared absorption spectrum. The inhibitory effect of the compound against breast cancer cell lines was measured by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Its effect on angiogenesis was evaluated by measuring vascular endothelial growth factor (VEGF) levels in treated cells. The ability of the compound to induce apoptosis in cancer cells was tested by measuring caspase-3 activity, and its capacity to stimulate the immune system was evaluated by measuring the levels of interferon gamma (IFN-γ), interleukin-2 (IL-2), IL-4, and IL-10 cytokines in treated lymphocytes. Results Significant antiproliferative activity against breast cancer cell lines was observed in treated cells. Low levels of VEGF and high caspase-3 activity were observed in treated cells. Levels of IFN-γ, IL-2, and IL-4 were increased after treating lymphocytes with this compound. Conclusion 3-(4-Bromo phenylazo)-2,4-pentanedione is a promising anticancer agent that can inhibit breast cancer cells through apoptosis induction and angiogenesis inhibition. Further testing is needed to clearly determine the molecular mechanisms of the anticancer effect of this compound.

Abstract
Photodynamic therapy (PDT) is a promising anticancer treatment and is clinically approved for different types of tumors. However, current PDT suffers several obstacles, including its neutralization by excess glutathione (GSH) in the tumor tissue and its strongly proangiogenic tumor response. In this work, a biomimic, multifunctional nanoparticle-based PDT agent, combining a tumor-targeted photosensitizer with GSH scavenging and antiangiogenesis therapy, is developed. A porphyrinic Zr-metal-organic framework nanoparticle is used simultaneously as the photosensitizer and the delivery vehicle of vascular endothelial growth factor receptor 2 (VEGFR2) inhibitor apatinib. The core nanoparticles are wrapped in MnO2 to consume the intratumoral GSH and then decorated with a tumor cell membrane camouflage. After intravenous administration, the nanoparticles selectively accumulate in tumor through homotypic targeting mediated by the biomimic decoration, and the combination of enhanced PDT and antiangiogenic drug significantly improves their tumor inhibition efficiency. This study provides an integrated solution for mechanism-based enhancement of PDT and demonstrates the encouraging potential for multifunctional nanosystem applicable for tumor therapy.

Abstract
Angiogenesis inhibition with bevacizumab, a monoclonal antibody against vascular endothelial growth factor A (VEGF-A), is an anticancer treatment associated with hypertension and renal glomerular toxicity referred to as a preeclampsia-like syndrome. In preeclampsia, podocyturia predates proteinuria and clinical features of preeclampsia, and is regarded as a biomarker of ongoing glomerular injury. Using a quantitative polymerase chain reaction of the podocyte-specific molecules nephrin, podocin, and VEGF-A in the urine, we examined whether podocyturia is present in bevacizumab-treated cancer patients, and whether it relates to proteinuria and the cumulative dose of bevacizumab. Urine samples were cross-sectionally collected from 43 bevacizumab-treated patients, 21 chemotherapy-treated patients, and 7 healthy controls. Urinary protein-to-creatinine ratio (mean and range) was 32.0 mg/mmol (5.2-284.4) in the bevacizumab group, compared with 11.4 mg/mmol (1.1-21.0) in the chemotherapy group and 7.4 mg/mmol (3.9-16.5) (P < .05) in healthy controls, whereas urinary albumin-to-creatinine ratio values in the three groups were, respectively, 18.9 mg/mmol (0.1-227.7), 1.5 mg/mmol (0.2-3.5), and 0.2 mg/mmol (0.1-0.4) (P < .05). The cumulative dose of bevacizumab ranged from 550 to 93,628 mg. Urinary podocin mRNA expression was undetectable in 59% of participants, urinary nephrin mRNA expression per mmol creatinine ranged from 0.0 to 5.3 and urinary VEGF-A mRNA expression from 0.0 to 2.7. Urinary nephrin mRNA expression did not correlate to the albumin-to-creatinine ratio or the cumulative dose of bevacizumab, whereas the latter correlated with the albumin-to-creatinine ratio (r = 0.77; P < .001). Our results demonstrate that the cumulative dose of bevacizumab is closely correlated with albuminuria but not with podocyturia as measured with the quantitative polymerase chain reaction technique, challenging the feasibility of this measurement to monitor ongoing glomerular injury in patients chronically treated with bevacizumab.

Abstract
BACKGROUND/AIM We aimed to identify the most effectual groups of targeted therapies for ovarian cancer in recent clinical trials. MATERIALS AND METHODS A systematic literature review has been gathered on an inventive study design that comprises of five steps. This involves search for pertinent publications from 2010 to date in various accessible medical data bases, usage of inclusion and exclusion, appraisal of quality of the studies included, abstraction of the relevant data and intelligible amalgamation of the data abridged in an evocative and narrative style. RESULTS Three types of modalities of targeted-therapy drugs have been identified; angiogenesis inhibition, signal enzymes inhibition and apoptosis induction in the tumor cells. CONCLUSION There has been a surge in clinical trials with drugs that specifically target signal enzymes, induce apoptosis and inhibit angiogenesis in site-specific ovarian cancer cells, which could be very promising to design a more efficacious protocol for treating the disease.

Abstract
The effects of GK-1, a monomeric dipeptide mimetic of nerve growth factor (NGF) loop 4, on angiogenesis were studied in vitro and in vivo. Experiments on human umbilical vein endothelial cells HUVEC showed that the test compound did not affect tubulogenesis (initial stage of angiogenesis) and prevented realization of the angiogenic effect of NGF and its dimeric dipeptide mimetic GK-2. Experiments on rat hind limb ischemia model demonstrated that GK-1 (1 mg/kg/day intraperitoneally over 14 days) significantly reduced the density of the capillary network in ischemic tissue and increased the number and area of Zenker necrosis in comparison with the control. These data suggest that GK-1 exhibits a pronounced antiangiogenic activity.

Abstract
In response to salt loading, Na+ and Cl- accumulate in the skin in excess of water, stimulating skin lymphangiogenesis via activation of the mononuclear phagocyte system cell-derived vascular endothelial growth factor-C-vascular endothelial growth factor type 3 receptor signaling pathway. Inhibition of this pathway results in salt-sensitive hypertension. Sunitinib is an antiangiogenic, anticancer agent that blocks all 3 vascular endothelial growth factor receptors and increases blood pressure. We explored the salt dependency of sunitinib-induced hypertension and whether impairment of skin lymphangiogenesis is an underlying mechanism. Normotensive Wistar-Kyoto rats were exposed to a normal or high salt with or without sunitinib administration. Sunitinib induced a 15 mm Hg rise in telemetrically measured blood pressure, which was aggravated by a high-salt diet (HSD), resulting in a decline of the slope of the pressure-natriuresis curve. Without affecting body weight, plasma Na+ concentration or renal function, Na+ and Cl- skin content increased by 31% and 32% with the high salt and by 49% and 50% with the HSD plus sunitinib, whereas skin water increased by 17% and 24%, respectively. Skin mononuclear phagocyte system cell density increased both during sunitinib and a HSD, but no further increment was seen when HSD and sunitinib were combined. HSD increased skin lymphangiogenesis, while sunitinib tended to decrease lymphangiogenesis, both during a normal-salt diet and HSD. We conclude that sunitinib induces hypertension that is aggravated by high salt intake and not accompanied by impaired skin lymphangiogenesis.

Abstract
OBJECTIVE To determine the safety and clinical efficacy of two anti-angiogenic agents, bevacizumab and lenalidomide, with docetaxel and prednisone. PATIENTS AND METHODS Eligible patients with metastatic castration-resistant prostate cancer enrolled in this open-label, phase II study of lenalidomide with bevacizumab (15 mg/kg), docetaxel (75 mg/m(2) ) and prednisone (10 mg daily). Docetaxel and bevacizumab were administered on day 1 of a 3-week treatment cycle. To establish safety, lenalidomide dosing in this combination was escalated in a conventional 3 + 3 design (15, 20 and 25 mg daily for 2 weeks followed by 1 week off). Patients received supportive measures including prophylactic pegfilgrastim and enoxaparin. The primary endpoints were safety and clinical efficacy. RESULTS A total of 63 patients enrolled in this trial. Toxicities were manageable with most common adverse events (AEs) being haematological, and were ascertained by weekly blood counts. Twenty-nine patients (46%) had grade 4 neutropenia, 20 (32%) had grade 3 anaemia and seven (11%) had grade 3 thrombocytopenia. Despite frequent neutropenia, serious infections were rare. Other common non-haematological grade 3 AEs included fatigue (10%) and diarrhoea (10%). Grade 2 AEs in >10% of patients included anorexia, weight loss, constipation, osteonecrosis of the jaw, rash and dyspnoea. Of 61 evaluable patients, 57 (93%), 55 (90%) and 33 (54%) had PSA declines of >30, >50 and >90%, respectively. Of the 29 evaluable patients, 24 (86%) had a confirmed radiographic partial response. The median times to progression and overall survival were 18.2 and 24.6 months, respectively. CONCLUSIONS With appropriate supportive measures, combination angiogenesis inhibition can be safely administered and potentially provide clinical benefit. These hypothesis-generating data would require randomized trials to confirm the findings.

Abstract
BACKGROUND Antiangiogenic treatment with the multitargeted vascular endothelial growth factor (VEGF) receptor inhibitor sunitinib associates with a blood pressure (BP) rise and glomerular renal injury. Recent evidence indicates that VEGF derived from tubular cells is required for maintenance of the peritubular vasculature. In the present study, we focussed on tubular and glomerular pathology induced by sunitinib and explored whether a high salt (HS) diet augments the BP rise and renal abnormalities. METHODS Normotensive Wistar Kyoto (WKY) rats were exposed to a normal salt (NS) or HS diet for 2 weeks and subsequently for 8 days to sunitinib or vehicle administration after which the rats were euthanized and kidneys excised. Mean arterial pressure (MAP) was telemetrically measured. Urine was sampled for proteinuria and endothelinuria, and blood for measurement of endothelin-1, creatinine and cystatin C. RESULTS Compared with the NS diet, MAP rapidly rose by 27 ± 3 mmHg with the HS diet. On sunitinib, MAP rose further by 15 ± 1 with the NS and by 23 ± 4 mmHg with the HS diet (P < 0.05). The HS diet itself had no effect on proteinuria, endothelinuria or the plasma levels of endothelin-1, creatinine and cystatin C. Only with the HS diet, sunitinib administration massively increased proteinuria and endothelinuria and these two parameters were related (r = 0.50, P < 0.01). Likewise, renal glomerular pathology was enhanced during sunitinib with the HS diet, whereas tubulointerstitial injury or reduced peritubular capillary density did not occur. CONCLUSIONS An HS diet induces a marked BP rise in WKY rats and exacerbates both the magnitude of the BP rise and glomerular injury induced by sunitinib.

Abstract
Methyl dihydrojasmonate (MJ) has been studied because of its application as an antitumor drug compound. However, as MJ is a poorly water-soluble compound, a suitable oil-in-water microemulsion (ME) has been studied in order to provide its solubilization in an aqueous media and to allow its administration by the parenteral route. The ME used in this work was characterized on the pseudo-ternary phase diagram by dynamic light scattering and rheological measurements. Regardless of the drug presence, the droplet size was directly dependent on the oil/surfactant (O/S) ratio. Furthermore, the drug incorporation into the ME significantly increased the ME diameter, mainly at low O/S ratios. The rheological evaluation of the systems showed that in the absence of drug a Newtonian behavior was observed. On the other hand, in the presence of MJ the ME systems revealed pseudoplastic behavior, independently of the O/S ratio. The in vivo studies demonstrated that not only was the effect on the tumor inhibition inversely dependent on the MJ-loaded ME administered dose, but also it was slightly higher than the doxorubicin alone, which was used as the positive control. Additionally, a small antiangiogenic effect for MJ-loaded ME was found at doses in which it possesses antitumor activity. MJ revealed to be nontoxic at doses higher than 350 mg/kg, which was higher than the dose that provides tumor-inhibition effect in this study. Because the MJ-loaded ME was shown to have anticancer activity comparable to doxorubicin, the ME described here may be considered a suitable vehicle for parenteral administration of MJ.

Abstract
This phase 1 study evaluated the safety and tolerability of antiangiogenic therapy using vandetanib and metronomic cyclophosphamide and methotrexate in metastatic breast cancer. Eligible patients had metastatic breast cancer with 0-4 prior chemotherapy regimens. All received cyclophosphamide 50 mg daily, methotrexate 2.5 mg days 1-2 weekly, and vandetanib daily in 3 dose-escalation cohorts: 100 mg (C1), 200 mg (C2), and 300 mg (C3). The primary endpoint was safety and tolerability; secondary endpoints included response rate and evaluation of platelet-associated proteins. Twenty three patients were treated and evaluable for toxicity. Common mild toxicities included nausea, vomiting, LFTs abnormalities, fatigue, and rash. Three episodes of dose-limiting toxicity occurred in C3. In all cohorts, 1/3 of patients required vandetanib dose reduction, and 22 % ended therapy for toxicity. Of the 20 response-evaluable patients, 10 % demonstrated partial response and 15 % stable disease ≥24 weeks. Proteomic analyses demonstrated changes in platelet content of angiogenesis regulators, including vascular endothelial growth factor and platelet factor 4, with exposure to therapy. This regimen was tolerable at a maximum vandetanib dose of 200 mg; modest clinical activity was observed in this heavily pretreated population. Changes in the platelet proteome may serve as pharmacodynamic markers of angiogenesis inhibition. Metronomic chemotherapy is an attractive partner with biologics and deserves further study in metastatic breast cancer.

Abstract
PURPOSE We assessed the clinical activity and safety of gemcitabine plus capecitabine in patients with metastatic renal cell cancer previously treated with immunotherapy. MATERIALS AND METHODS In this phase II trial patients received 1,000 mg/m(2) gemcitabine intravenously on days 1, 8 and 15, plus 830 mg/m(2) capecitabine orally twice daily on days 1 to 21 of 28-day cycles. The primary end point was progression-free survival time. Secondary end points included overall survival time, objective response rate and toxicity. RESULTS Of 84 patients enrolled 83 were evaluable for response and toxicity. A total of 65 patients had intermediate or poor risk prognosis. Median progression-free survival and overall survival were 4.6 (95% CI 3.7-7.3) and 17.9 months (95% CI 13.2-23.6), respectively. There were 6 partial responses and 1 complete response (objective response rate 8.4% [95% CI 3.5-16.6]). Two patients remain in unmaintained remission close to 3 years from the initiation of gemcitabine plus capecitabine treatment. On multivariate analysis more than 3 disease sites were significantly associated with shorter progression-free survival and patients with thrombocytosis, more than 3 disease sites or anemia had a significantly increased risk of death. Adverse events occurring at least once in more than 5% of patients included grade 3 or greater neutropenia (83%), grade 2 or greater hand-foot syndrome (13%), grade 3 or greater thrombocytopenia (12%), grade 3 or greater thromboembolic events (8%), grade 3 or greater fatigue (8%) and grade 2 or greater mucositis (6%). CONCLUSIONS At the doses and schedule tested gemcitabine plus capecitabine demonstrated modest clinical activity in metastatic renal cell cancer after cytokine failure and produced significant neutropenia. A modified gemcitabine plus capecitabine regimen may be evaluated in patients with metastatic renal cell cancer after failure of approved targeted therapies.

Abstract
Collagen type XVIII (C18) is a nonfibrillar collagen of basement membranes. Its C-terminal fragment, endostatin, has been identified as an inhibitor of angiogenesis. C18 is predominantly expressed by hepatocytes of normal, cirrhotic and neoplastic liver. We compared the patterns of C18 RNA-expression in colonic adenocarcinoma metastases, which represent the most frequently occurring liver tumours, to normal colon mucosa, to primary colon cancers and to ovarian cancers which are often morphologically similar to colonic cancer or metastasis. Two C18-specific RNA-probes were generated to perform in situ hybridization combined with immunohistochemistry for cytokeratin, vimentin and the endothelial marker CD31, in order to characterize the C18-expressing cells. C18/endostatin protein was localized by immunohistology. In colorectal carcinomas and their liver metastases high levels of C18 transcripts were observed in endothelial cells and fibroblasts/myofibroblasts, whereas C18 RNA was virtually absent from carcinoma cells. Ovarian carcinomas displayed high C18 RNA expression both in carcinoma and stromal cells, indicating that induction of C18 transcription in tumour stromal cells is independent of the ability of carcinoma cells to express C18. While the role of tumour cell derived C18 in cancer growth regulation remains unknown, stimulation of proteolysis of the locally strongly expressed C18 to endostatin could offer an attractive approach for a targeted antineoplastic therapy.

Abstract
Clotrimazole, an imidazole antimycotic, interferes with the rise in cytosolic Ca2+ and inhibits cell proliferation in a reversible manner. Here we describe the effect of clotrimazole on vascular endothelial cells (ECs). Clotrimazole inhibited the proliferation of ECs stimulated with typical angiogenic growth factors; vascular endothelial growth factor and basic fibroblast growth factor (bFGF). This inhibitory effect of clotrimazole was dose-dependent and the maximal inhibition was observed at a concentration of 10 mM. We did not observe any increase in 51Cr release from ECs during treatment with 10 microM clotrimazole. Moreover, clotrimazole inhibited the basal and bFGF-stimulated migration of ECs. As clotrimazole inhibited two principle components of angiogenesis; the proliferation and migration of ECs, we examined whether clotrimazole inhibited angiogenesis. Tube formation by ECs in type 1 collagen gel was investigated, and clotrimazole was found to be significantly inhibitory. The inhibitory effect of clotrimazole on angiogenesis was further confirmed in an in vivo angiogenesis model of murine Matrigel plug assay. These results demonstrate that clotrimazole is a potent inhibitor of angiogenesis.
