Abstract
Exosomes are a subpopulation of extracellular vesicles (EVs) secreted by cells. In cancer, they are key cellular messengers during cancer development and progression. Tumor-derived exosomes (TEXs) promote cancer progression. In oral cancer, the major complication is oral squamous cell carcinoma (OSCC). Exosomes show strong participation in several OSCC-related activities such as uncontrolled cell growth, immune suppression, angiogenesis, metastasis, and drug and therapeutic resistance. It is also a potential biomarker source for oral cancer. Some therapeutic exosome sources such as stem cells, plants (it is more effective compared to others), and engineered exosomes reduce oral cancer development. This therapeutic approach is effective because of its specificity, biocompatibility, and cell-free therapy (it reduced side effects in cancer treatment). This article highlights exosome-based theranostics signatures in oral cancer, clinical trials, challenges of exosome-based oral cancer research, and future improvements. In the future, exosomes may become an effective and affordable solution for oral cancer.

The novel drug candidate S2/IAPinh improves survival in models of pancreatic and ovarian cancer. Sci Rep 2024; 14:6373. [PMID: 38493257 PMCID: PMC10944456 DOI: 10.1038/s41598-024-56928-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Accepted: 03/12/2024] [Indexed: 03/18/2024] Open
Abstract
Cancer selective apoptosis remains a therapeutic challenge and off-target toxicity has limited enthusiasm for this target clinically. Sigma-2 ligands (S2) have been shown to enhance the cancer selectivity of small molecule drug candidates by improving internalization. Here, we report the synthesis of a novel drug conjugate, which was created by linking a clinically underperforming SMAC mimetic (second mitochondria-derived activator of caspases; LCL161), an inhibitor (antagonist) of inhibitor of apoptosis proteins (IAPinh) with the sigma-2 ligand SW43, resulting in the new chemical entity S2/IAPinh. Drug potency was assessed via cell viability assays across several pancreatic and ovarian cancer cell lines in comparison with the individual components (S2 and IAPinh) as well as their equimolar mixtures (S2 + IAPinh) both in vitro and in preclinical models of pancreatic and ovarian cancer. Mechanistic studies of S2/IAPinh-mediated cell death were investigated in vitro and in vivo using syngeneic and xenograft mouse models of murine pancreatic and human ovarian cancer, respectively. S2/IAPinh demonstrated markedly improved pharmacological activity in cancer cell lines and primary organoid cultures when compared to the controls. In vivo testing demonstrated a marked reduction in tumor growth rates and increased survival rates when compared to the respective control groups. The predicted mechanism of action of S2/IAPinh was confirmed through assessment of apoptosis pathways and demonstrated strong target degradation (cellular inhibitor of apoptosis proteins-1 [cIAP-1]) and activation of caspases 3 and 8. Taken together, S2/IAPinh demonstrated efficacy in models of pancreatic and ovarian cancer, two challenging malignancies in need of novel treatment concepts. Our data support an in-depth investigation into utilizing S2/IAPinh for the treatment of cancer.

Abstract
Cancer is the most challenging global health crisis. In the recent times, studies on extracellular vesicles (EVs) are adding a new chapter to cancer research and reports on EVs explores cancer in a new dimension. Exosomes are a group of subpopulations of EVs. It originates from the endosomes and carries biologically active molecules to the neighboring cells which in turn transforms the recipient cell activity. In general, it plays a role in cellular communication. The correlation between exosomes and cancer is fascinating. Tumor-derived exosomes (TEXs) play a dynamic role in cancer progression and are associated with uncontrolled cell growth, angiogenesis, immune suppression, and metastasis. Its molecular cargo is an excellent source of cancer biomarkers. Several advanced molecular profiling approaches assist in exploring the TEXs in depth. This paves the way for a strong foundation for identifying and detecting more specific and efficient biomarkers. TEXs are also gaining importance in scientific society for its role in cancer therapy and several clinical trials based on TEXs is a proof of its significance. In this review, we have highlighted the role of TEXs in mediating immune cell reprogramming, cancer development, metastasis, EMT, organ-specific metastasis, and its clinical significance in cancer theranostics. TEXs profiling is an effective method to understand the complications associated with cancer leading to good health and well-being of the individual and society as a whole.

Abstract
Angiogenesis is an essential mechanism for the progression of gynecological cancers. Although approved anti-angiogenic drugs have demonstrated clinical efficacy in treating gynecological cancers, the full potential of therapeutic strategies based on tumor blood vessels has not yet been realized. This review summarizes the latest angiogenesis mechanisms involved in the progression of gynecological cancers and discusses the current clinical practice of approved anti-angiogenic drugs and related clinical trials. Given the close relationship between gynecological cancers and blood vessels, we highlight more delicate strategies for regulating tumor vessels, including wise drug combinations and smart nano-delivery platforms to achieve highly efficient drug delivery and overall vessel microenvironment regulation. We also address current challenges and future opportunities in this field. We aim to generate interest in therapeutic strategies that target blood vessels as a key entry point and offer new potential and inspiration for combating gynecological cancers.

Abstract
Tumor microenvironment, the soil where tumor thrives, plays a critical role in the development and progression of colorectal cancer (CRC). Various cell signaling molecules in the environment promote tumor angiogenesis, immune tolerance and facilitate immune escape. Exosomes, as messengers between tumor and host cells, are considered key mediators involved in the tumor-accelerating environment. However, the exosome-mediated communication networks in the CRC microenvironment are still largely unclear. In this review, we summarized the relationship between TME and CRC based on recent literature. Then, we revealed the unique impacts and signal molecules of exosomes on account of their regulatory role in the flora, hypoxia, inflammatory and immunological microenvironment of CRC. Finally, we summarized the therapeutically effective of exosomes in CRC microenvironment and discussed their current status and prospects, aiming to provide new molecular targets and a theoretical basis for the CRC treatment.

Abstract
Epithelial ovarian cancer (EOC) is one of the most lethal gynecological cancers despite a relatively low incidence. Angiogenesis, one of the hallmarks of cancer, is essential for the pathogenesis of EOC, which is related to the induction of angiogenic factors. We found that ELF3 was highly expressed in EOCs under hypoxia and functioned as a transcription factor for IGF1. The ELF3‐mediated increase in the secretion of IGF1 and VEGF promoted endothelial cell proliferation, migration, and EOC angiogenesis. Although this situation was much exaggerated under hypoxia, ELF3 silencing under hypoxia significantly attenuated angiogenic activity in endothelial cells by reducing the expression and secretion of IGF1 and VEGF. ELF3 silencing attenuated angiogenesis and tumorigenesis in ex vivo and xenograft mouse models. Consequently, ELF3 plays an important role in the induction of angiogenesis and tumorigenesis in EOC as a transcription factor of IGF1. A detailed understanding of the biological mechanism of ELF3 may both improve current antiangiogenic therapies and have anticancer effects for EOC.

Abstract
Throughout the female menstrual cycle, physiological changes occur that affect the biodistribution of nanoparticles within the reproductive system. We demonstrate a 2-fold increase in nanoparticle accumulation in murine ovaries and uterus during ovulation, compared to the nonovulatory stage, following intravenous administration. This biodistribution pattern had positive or negative effects when drug-loaded nanoparticles, sized 100 nm or smaller, were used to treat different cancers. For example, treating ovarian cancer with nanomedicines during mouse ovulation resulted in higher drug accumulation in the ovaries, improving therapeutic efficacy. Conversely, treating breast cancer during ovulation, led to reduced therapeutic efficacy, due to enhanced nanoparticle accumulation in the reproductive system rather than at the tumor site. Moreover, chemotherapeutic nanoparticles administered during ovulation increased ovarian toxicity and decreased fertility compared to the free drug. The menstrual cycle should be accounted for when designing and implementing nanomedicines for females.

Abstract
The relationship between psychosocial factors and cancer has intrigued people for centuries. In the last several decades there has been an expansion of mechanistic research that has revealed insights regarding how stress activates neuroendocrine stress-response systems to impact cancer progression. Here, we review emerging mechanistic findings on key pathways implicated in the effect of stress on cancer progression, including the cellular immune response, inflammation, angiogenesis, and metastasis, with a primary focus on the mediating role of the sympathetic nervous system. We discuss converging findings from preclinical and clinical cancer research that describe these pathways and research that reveals how these stress pathways may be targeted via pharmacological and mind-body based interventions. While further research is required, the body of work reviewed here highlights the need for and feasibility of an integrated approach to target stress pathways in cancer patients to achieve comprehensive cancer treatment.

Abstract
BACKGROUND The aim of this study was to evaluate the impact of Lymphovascular Space Invasion (LVSI) on Overall Survival (OS) and Recurrence-Free Survival (RFS) in patients managed for high-grade serous epithelial ovarian cancer (HGSOC). MATERIALS AND METHODS Retrospective multicenter study by the FRANCOGYN research group between January 2001 and December 2018. All patients managed for HGSOC and for whom histological slides for the review of LVSI were available, were included. The characteristics of patients with LVSI (LVSI group) were compared to those without LVSI (No LVSI group). A Cox analysis for OS and RFS analysis was performed in all populations. RESULTS Over the study period, 410 patients were included in the thirteen institutions. Among them, 289 patients had LVSI (33.9%). LVSI was an independent predictive factor for poorer Overall and Recurrence-Free Survival. LVSI affected OS (p<0.001) and RFS (p<0.001), Association of LVSI status and estrogen receptor status (ER) also affected OS and RFS (p=0.04; p=0.04 respectively). CONCLUSION The presence of LVSI in HGSOC has an impact on OS and RFS and should be routinely included in the pathology examination along with ER status.

Lymphovascular space invasion as a prognostic factor of epithelial ovarian cancer: a multicenter study by the FRANCOGYN group. Arch Gynecol Obstet 2021; 304:1577-1585. [PMID: 34184114 DOI: 10.1007/s00404-021-06110-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2020] [Accepted: 05/28/2021] [Indexed: 12/24/2022]
Abstract
BACKGROUND The presence of lymphovascular space invasion (LVSI) is not yet included in international recommendations neither as a prognostic factor nor as a parameter for the decision to use adjuvant chemotherapy in FIGO stage I/IIa ovarian cancer (OC). OBJECTIVE This study set out to evaluate the impact of LVSI on Overall Survival (OS) and Recurrence-Free Survival (RFS) in patients managed for epithelial OC. DESIGN Retrospective multicenter study by the research group FRANCOGYN between January 2001 and December 2018. All patients managed for epithelial OC surgery and for whom histological slides for the review of LVSI were available, were included. The characteristics of patients with LVSI (LVSI group) were compared to those without LVSI (No-LVSI group). A Cox analysis for OS and RFS analysis was performed in all the populations. SETTING French multicenter tertiary care centers RESULTS: Over the study period, 852 patients were included in the 13 institutions. Among them, 289 patients had LVSI (33.9%). There was a significant difference in the distribution of LVSI between early and advanced stages (p < 0.001). LVSI was an independent predictive factor for poorer Overall and Recurrence-Free Survival. LVSI affected OS (p < 0.001) and RFS (p < 0.001), LVSI affected OS and RFS for early stages (p = 0.001; p = 0.001, respectively) and also for advanced stages (p = 0.01; p = 0.009, respectively). CONCLUSION The presence of LVSI in epithelial ovarian epithelial tumors has an impact on OS and RFS and should be included in the routine pathology examination to adapt therapeutic management, especially for women in the early stages of the disease.

Abstract
BACKGROUND Treatment of patients with platinum resistant/refractory epithelial ovarian cancer (EOC) is an unmet need. We evaluated the role of oral metronomic therapy in this setting. PATIENTS AND METHODS Between October 2017 and September 2019 seventy five patients with platinum resistant/refractory EOC were enrolled. Patients received oral etoposide (50 mg, day 1 to 14, cyclophosphamide 50 mg, day 1 to 28, every 4 weeks (Arm A, n = 38). Patients in Arm- B (n = 37) received Pazopanib (400 mg once daily) in addition to etoposide and cyclophosphamide. Quality of life (QoL) was evaluated using the EORTC questionnaire. Serum VEGF and PDGF were estimated at baseline, after 3rd and 6th cycle. The primary endpoint was progression free survival (PFS). Secondary endpoints were overall survival (OS), toxicity and QoL. RESULTS Patients characteristics were well matched. Median PFS was higher in arm B, 5.1 months (95% CI 3.13 to10.33) compared to 3.4 months (95% CI 3.0 to 6.53) in arm A, p = 0.045. Median OS has 'not reached' in Arm B compared to 11.2 months (95% CI, 5.66 - not reached) in arm A, p = 0.032. Therapy was tolerated well; oral mucositis (p = 0.36) and fatigue (p = 0.08) being more in arm B. QoL assessment revealed modest improvement in 'symptom scales' in Arm B. Serum VEGF and PDGF levels decreased with therapy in both arms (Arm A-p < 0.0001, Arm B-p < 0.016). CONCLUSION Addition of pazopanib to etoposide and cyclophosphamide could be a novel oral combination for metronomic therapy for platinum resistant/refractory EOC. TRIAL REGISTRATION CTRI/2017/10/010219.

Early hypertension and neutropenia are predictors of treatment efficacy in metastatic colorectal cancer patients administered FOLFIRI and vascular endothelial growth factor inhibitors as second-line chemotherapy. Cancer Med 2021; 10:615-625. [PMID: 33347731 PMCID: PMC7877370 DOI: 10.1002/cam4.3638] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2020] [Revised: 11/11/2020] [Accepted: 11/16/2020] [Indexed: 12/11/2022] Open
Abstract
BACKGROUND Three vascular endothelial growth factor (VEGF) inhibitors, Bevacizumab (BEV), ramucirumab (RAM), and aflibercept (AFL), are widely used for metastatic colorectal cancer (mCRC) patients who are treated with second-line chemotherapy. The difference in outcome between the three drugs has not been evaluated. In contrast to epidermal growth factor receptor inhibitors, VEGF inhibitors have few candidate predictors of efficacy. METHODS Consecutive mCRC patients who were treated with second-line chemotherapy were retrospectively enrolled. Overall response rate (ORR), progression-free survival (PFS), overall survival (OS), and safety were assessed. Subgroup analyses of prognostic and predictive efficacy markers were performed. RESULTS A total of 119 (41.2%), 107 (37.0%), and 63 patients (21.8%) were treated with FOLFIRI +BEV, RAM, or AFL, respectively. ORR, PFS, and OS showed no significant differences between three groups. However, the frequency of grade 3 or 4 adverse events (AEs) in the FOLFIRI +AFL group was significantly higher than that in the other groups (p < 0.001). Patients with grade 3 or 4 AEs, especially hypertension and neutropenia within the first four cycles of treatment had significantly longer PFS and OS than those without AEs, irrespective of treatment with VEGF inhibitors (p < 0.001). PFS in patients without prior BEV exposure was also significantly longer than that in patients with prior BEV exposure (p = 0.003). CONCLUSIONS Chemotherapeutic efficacy did not differ between the groups. Grade 3 or 4 AEs within the first four cycles of treatment and prior BEV exposure may be an effective predictor of treatment efficacy in mCRC patients administered VEGF inhibitors as second-line chemotherapy.

Abstract
Background The prognosis for advanced hepatocellular carcinoma (HCC) remains clinically unsatisfying. Apatinib has proven to be a very effective treatment for advanced HCC in our previous retrospective study. Our aim in this study was to evaluate the efficacy, safety, and toxicity of apatinib in patients with advanced HCC. Methods This single-arm, open-label phase II clinical trial enrolled patients with advanced HCC. These patients received apatinib, 500 mg once daily, until disease progression, unacceptable toxicity, consent withdrawal, or death. One treatment cycle consisted of 4 weeks of apatinib treatment. The response evaluation criteria in solid tumors (RECIST) was used to assess tumor response every 1–2 cycles. The primary endpoint was the objective response rate (ORR), while the secondary endpoints were the overall survival (OS), progression-free survival (PFS), disease control rate (DCR), and toxicity. Results Between December 2016 and June 2018, 23 patients were enrolled in the study, 22 of whom were available for response evaluation. The cutoff date was August 10, 2018. The overall ORR and DCR were 30.4% and 65.2%, respectively. The median OS and PFS were 13.8 (95% CI: 5.3–22.3) and 8.7 (95% CI: 5.9–11.1) months, respectively. The most common treatment-related adverse events were proteinuria (39.1%), hypertension (34.8%), and hand-foot-skin reaction (34.8%). Conclusions Apatinib showed robust clinical activity in patients with advanced HCC. Moreover, apatinib was safe to use, well tolerated, and had acceptable toxicity. (NCT03046979).

Homeoprotein Msx1-PIASy Interaction Inhibits Angiogenesis. Cells 2020; 9:cells9081854.

Abstract
Previously, we demonstrated that the homeoprotein Msx1 interaction with p53 inhibited tumor growth by inducing apoptosis. However, Msx1 can exert its tumor suppressive effect through the inhibition of angiogenesis since growth of the tumor relies on sufficient blood supply from the existing vessels to provide oxygen and nutrients for tumor growth. We hypothesized that the inhibition of tumor growth by Msx1 might be due to the inhibition of angiogenesis. Here, we explored the role of Msx1 in angiogenesis. Overexpression of Msx1 in HUVECs inhibited angiogenesis, and silencing of Msx1 by siRNA abrogated its anti-angiogenic effects. Furthermore, forced expression of Msx1 in mouse muscle tissue inhibited vessel sprouting, and application of an Ad-Msx1-transfected conditioned medium onto the chicken chorioallantoic membrane (CAM) led to a significant inhibition of new vessel formation. To explore the underlying mechanism of Msx1-mediated angiogenesis, yeast two-hybrid screening was performed, and we identified PIASy (protein inhibitor of activated STAT Y) as a novel Msx1-interacting protein. We mapped the homeodomain of Msx1 and the C-terminal domain of PIASy as respective interacting domains. Consistent with its anti-angiogenic function, overexpression of Msx1 suppressed the reporter activity of VEGF. Interestingly, PIASy stabilized Msx1 protein, whereas deletion of the Msx1-interacting domain in PIASy abrogated the inhibition of tube formation and the stabilization of Msx1 protein. Our findings suggest the functional importance of PIASy-Msx1 interaction in Msx1-mediated angiogenesis inhibition.

Abstract
Background & objectives: Advanced epithelial ovarian cancer (EOC) is associated with dismal outcome and progression-free survival (PFS) shortens with each subsequent relapse. For patients with recurrent and platinum refractory disease, therapeutic options are limited. Oral metronomic therapy (OMT) is associated with symptomatic relief and stable response in a significant proportion of patients. We retrospectively evaluated the outcome of patients with EOC treated with OMT at a tertiary care hospital in north India. Methods: Between January 2011 to December 2017, 36 EOC patients received OMT. Patients’ median age was 50 yr (range, 38-81 yr) and they had received a median of two lines of prior chemotherapy. OMT regimen included a combination of cyclophosphamide, etoposide (VP-16) and celecoxib with or without pazopanib along with supportive care. Response rates and outcomes were ascertained using the Gynecological Cancer Intergroup Guidelines. The toxicity was graded according to the Common Terminology Criteria for Adverse Events v.4.03. Results: The median CA-125 before initiating OMT was 160 U/ml (range, 42.23-5330 U/ml). The median interval between last chemotherapy and starting OMT regimen was 159 days (range, 1-1211 days). The overall response rate was 50 per cent. The median progression-free survival (PFS) was 8.2 months [95% confidence interval (CI): 5.03-10.33], and the median overall survival was 38 months (95% CI: 25.6-NR). Patients who received two lines of chemotherapy before OMT (P=0.052) and those who received pazopanib-based OMT (P=0.0513) had better PFS. Interpretation & conclusions: For patients with relapse and refractory EOC, OMT could be a reasonable option. A combination of oral etoposide (VP-16) and pazopanib needs further evaluation in a large number of patients in a randomized trial.

Abstract
Recent developments in MR hardware and software have allowed a surge of interest in intravoxel incoherent motion (IVIM) MRI in oncology. Beyond diffusion-weighted imaging (and the standard apparent diffusion coefficient mapping most commonly used clinically), IVIM provides information on tissue microcirculation without the need for contrast agents. In oncology, perfusion-driven IVIM MRI has already shown its potential for the differential diagnosis of malignant and benign tumors, as well as for detecting prognostic biomarkers and treatment monitoring. Current developments in IVIM data processing, and its use as a method of scanning patients who cannot receive contrast agents, are expected to increase further utilization. This paper reviews the current applications, challenges, and future trends of perfusion-driven IVIM in oncology.

Abstract
BACKGROUND Ovarian cancer remains the most deadly gynecologic cancer with the majority of patients relapsing within 3 years of diagnosis. Traditional treatment paradigms linked to platinum sensitivity or resistance are currently being questioned in the setting of new diagnostic methods and treatment options. DESIGN Authors carried out review of the literature on key topics in treatment of recurrent epithelial ovarian cancer (EOC) when platinum is still an option; including secondary surgical cytoreduction, chemotherapy, novel treatment options, and maintenance therapy. A treatment algorithm is proposed. RESULTS Molecular characterization of EOC is critical to help guide treatment decisions. The role of secondary cytoreductive surgery is currently being evaluated with results from Gynecologic Oncology Group (GOG) 213 and anticipated results from DESKTOP III clinical trials. Chemotherapy backbone has remained relatively unchanged but utilizing non-platinum-based regimens is under investigation. In addition, maintenance therapy with anti-angiogenic therapy and Poly (ADP-ribose) Polymerase (PARP) inhibitors has emerged as the standard of care. Novel combinations, including immunotherapy and anti-angiogenesis agents, may further change the current landscape. CONCLUSIONS The treatment of recurrent EOC is rapidly changing. Clinical trial design will need to continue to evolve as many novel therapies move to the upfront setting. Ultimately, the treatment of patients with recurrent EOC must incorporate individual patient and tumor factors.

Abstract
Tumor-derived exosomes (TDEs) participate in formation and progression of different cancer processes, including tumor microenvironment (TME) remodeling, angiogenesis, invasion, metastasis and drug-resistance. Exosomes initiate or suppress various signaling pathways in the recipient cells via transmitting heterogeneous cargoes. In this review we discuss exosome biogenesis, exosome mediated metastasis and chemoresistance. Furthermore, tumor derived exosomes role in tumor microenvironment remodeling, and angiogenesis is reviewed. Also, exosome induction of epithelial mesenchymal transition (EMT) is highlighted. More importantly, we discuss extensively how exosomes regulate drug resistance in several cancers. Thus, understanding exosome biogenesis, their contents and the molecular mechanisms and signaling pathways that are responsible for metastasis and drug-resistance mediated by TDEs may help to devise novel therapeutic approaches for cancer progression particularly to overcome therapy-resistance and preventing metastasis as major factors of cancer mortality.

Abstract
The occurrence of chemotherapy-resistant tumors makes ovarian cancer (OC) the most lethal gynecological malignancy. While many factors may contribute to chemoresistance, the mechanisms responsible for regulating tumor vulnerability are under investigation. Our analysis of gene expression data revealed that Sab, a mitochondrial outer membrane (MOM) scaffold protein, was down-regulated in OC patients. Sab-mediated signaling induces cell death, suggesting that this apoptotic pathway is diminished in OC. We examined Sab expression in a panel of OC cell lines and found that the magnitude of Sab expression correlated to chemo-responsiveness; wherein, OC cells with low Sab levels were chemoresistant. The Sab levels were reflected by a corresponding amount of stress-induced c-Jun N-terminal kinase (JNK) on the MOM. BH3 profiling and examination of Bcl-2 and BH3-only protein concentrations revealed that cells with high Sab concentrations were primed for apoptosis, as determined by the decrease in pro-survival Bcl-2 proteins and an increase in pro-apoptotic BH3-only proteins on mitochondria. Furthermore, overexpression of Sab in chemoresistant cells enhanced apoptotic priming and restored cellular vulnerability to a combination treatment of cisplatin and paclitaxel. Contrariwise, inhibiting Sab-mediated signaling or silencing Sab expression in a chemosensitive cell line resulted in decreased apoptotic priming and increased resistance. The effects of silencing on Sab on the resistance to chemotherapeutic agents were emulated by the silencing or inhibition of JNK, which could be attributed to changes in Bcl-2 protein concentrations induced by sub-chronic JNK inhibition. We propose that Sab may be a prognostic biomarker to discern personalized treatments for OC patients.

Abstract
Epithelial ovarian carcinomas (EOC) cause more mortality than any other cancer of the female reproductive system. New therapeutic approaches to reduce EOC mortality have been largely unsuccessful due to the poor understanding of the mechanisms underlying EOC proliferation and metastasis. Progress in EOC treatment is further hampered by a lack of reliable prognostic biomarkers for early risk assessment. In this study, we identify that Migration-Inducting Gene 7 (MIG-7) is specifically induced in human EOC tissues but not normal ovaries or ovarian cyst. Ovarian MIG-7 expression strongly correlated with EOC progression. Elevated MIG-7 level at the time of primary cytoreductive surgery was a strong and independent predictor of poor survival of EOC patients. Cell and murine xenograft models showed that MIG-7 was required for EOC proliferation and invasion, and MIG-7 enhanced EOC-associated angiogenesis by promoting the expression of vascular endothelial growth factor. Inhibiting MIG-7 by RNA interference in grafted EOC cells retarded tumor growth, angiogenesis and improved host survival, and suppressing MIG-7 expression with a small molecule inhibitor D-39 identified from the medicinal plant Liriope muscari mitigated EOC growth and invasion and specifically abrogated the expression of vascular endothelial growth factor. Our data not only reveal a critical function of MIG-7 in EOC growth and metastasis and support MIG-7 as an independent prognostic biomarker for EOC, but also demonstrate that therapeutic targeting of MIG-7 is likely beneficial in the treatment of EOC.

[PMID: 29248198 DOI: 10.1016/j.ygyno.2017.12.013] [Citation(s) in RCA: 52] [Impact Index Per Article: 7.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2017] [Revised: 12/08/2017] [Accepted: 12/10/2017] [Indexed: 11/17/2022]
Abstract
OBJECTIVE Antiangiogenic treatments have been implicated to play a major role in epithelial ovarian cancer (EOC). Apatinib, a novel oral antiangiogenic agent targeting vascular endothelial growth factor receptor (VEGFR2), is currently being studied in different tumor types and is already used in gastric adenocarcinoma. This study was performed to assess the efficacy and safety of apatinib in patients with recurrent, pretreated EOC. PATIENTS AND METHODS Patients with recurrent, platinum-resistant, pre-treated EOC who failed available standard chemotherapy were enrolled. Apatinib was administered as 500mg daily. Primary objective is the overall response rate (ORR) according to MASS criteria. Secondary objectives are progression free survival (PFS), overall survival (OS), disease control rate (DCR), safety and tolerability. The treatment duration is until disease progression or intolerability of apatinib. RESULTS 29 eligible patients were enrolled in this multicenter, open-label, single arm study and received apatinib for a median of 36.8weeks (range 13-64.8weeks). Median follow-up time was 12months. 28 patients were eligible for efficacy analysis. ORR is 41.4% (95% confidence interval (CI), 23.3%-59.4%). DCR is 68.9% (95% CI, 52.1%-85.8%). Median PFS is 5.1months (95% CI, 3.8m-6.5m). Median OS is 14.5months (95% CI, 12.4m-16.4m). The most common treatment-related adverse events (AEs) were hand-foot syndrome (51.7%), hypertension (34.6%), nausea and vomiting (31.0%). 3 patients had no significant toxicity. 9 patients experienced grade 3 treatment-related AEs. CONCLUSIONS Apatinib 500mg daily p.o. is a feasible treatment in patients with recurrent, platinum-resistant, pretreated EOC. Multi-center prospective studies enrolling more patients are needed.

Abstract
Pharmaceutical research requires pre-clinical testing of new therapeutics using both in-vitro and in-vivo models. However, the species specificity of non-human in-vivo models and the inadequate recapitulation of physiological conditions in-vitro are intrinsic weaknesses. Here we show that perfusion is a vital factor for engineered human tissues to recapitulate key aspects of the tumour microenvironment. Organotypic culture and human tumour explants were allowed to grow long-term (14-35 days) and phenotypic features of perfused microtumours compared with those in the static culture. Differentiation status and therapeutic responses were significantly different under perfusion, indicating a distinct biological response of cultures grown under static conditions. Furthermore, heterogeneous co-culture of tumour and endothelial cells demonstrated selective cell-killing under therapeutic perfusion versus episodic delivery. We present a perfused 3D microtumour culture platform that sustains a more physiological tissue state and increased viability for long-term analyses. This system has the potential to tackle the disadvantages inherit of conventional pharmaceutical models and is suitable for precision medicine screening of tumour explants, particularly in hard-to-treat cancer types such as brain cancer which suffer from a lack of clinical samples.

Abstract
Myocyte enhancer factor 2D (MEF2D) is involved in many aspects of cancer progression, including cell proliferation, invasion, and migration. However, little is known about the role of MEF2D in tumor angiogenesis. Using clinical specimens, colorectal cancer (CRC) cell lines and a mouse model in the present study, we found that MEF2D expression was positively correlated with CD31-positive microvascular density in CRC tissues. MEF2D promoted tumor angiogenesis in vitro and in vivo and induced the expression of proangiogenic cytokines in CRC cells. MEF2D was found to be a downstream effector of hypoxia-inducible factor (HIF)-1α in the induction of tumor angiogenesis. HIF-1α transactivates MEF2D expression by binding to the MEF2D gene promoter. These results demonstrate that the HIF-1α/MEF2D axis can serve as a therapeutic target for the treatment of CRC.

Anti-tumour activity of tivozanib, a pan-inhibitor of VEGF receptors, in therapy-resistant ovarian carcinoma cells. Sci Rep 2017; 7:45954.

Abstract
Epithelial ovarian cancer (EOC) is the most fatal gynaecological malignancy. Despite initial therapeutic response, the majority of advanced-stage patients relapse and succumb to chemoresistant disease. Overcoming drug resistance is the key to successful treatment of EOC. Members of vascular endothelial growth factor (VEGF) family are overexpressed in EOC and play key roles in its malignant progression though their contribution in development of the chemoresistant disease remains elusive. Here we show that expression of the VEGF family is higher in therapy-resistant EOC cells compared to sensitive ones. Overexpression of VEGFR2 correlated with resistance to cisplatin and combination with VEGFR2-inhibitor apatinib synergistically increased cisplatin sensitivity. Tivozanib, a pan-inhibitor of VEGF receptors, reduced proliferation of the chemoresistant EOC cells through induction of G2/M cell cycle arrest and apoptotic cell death. Tivozanib decreased invasive potential of these cells, concomitant with reduction of intercellular adhesion molecule-1 (ICAM-1) and diminishing the enzymatic activity of urokinase-type plasminogen activator (uPA) and matrix metalloproteinase-2 (MMP-2). Moreover, tivozanib synergistically enhanced anti-tumour effects of EGFR-directed therapies including erlotinib. These findings suggest that the VEGF pathway has potential as a therapeutic target in therapy-resistant EOC and VEGFR blockade by tivozanib may yield stronger anti-tumour efficacy and circumvent resistance to EGFR-directed therapies.

Abstract
Over the last decade, there have been groundbreaking strides in our understanding of the multiple biological pathways by which psychosocial and behavioral factors can affect cancer progression. It is now clear that biobehavioral factors not only affect cellular immunity but both directly and indirectly modulate fundamental processes in cancer growth, including inflammation, angiogenesis, invasion, and metastasis. There is also an emerging understanding of how psychological and behavioral factors used in interventions can impact these physiological processes. This review outlines our current understanding of the physiological mechanisms by which psychological, social, and behavioral processes can affect cancer progression. The intervention literature is discussed, along with recommendations for future research to move the field of biobehavioral oncology forward.

Abstract
Deregulated expression of microRNAs has been associated with angiogenesis. Studying the miRNome of locally advanced breast tumors we unsuspectedly found a dramatically repression of miR-204, a small non-coding RNA with no previous involvement in tumor angiogenesis. Downregulation of miR-204 was confirmed in an independent cohort of patients and breast cancer cell lines. Gain-of-function analysis indicates that ectopic expression of miR-204 impairs cell proliferation, anchorage-independent growth, migration, invasion, and the formation of 3D capillary networks in vitro. Likewise, in vivo vascularization and angiogenesis were suppressed by miR-204 in a nu/nu mice model. Genome-wide profiling of MDA-MB-231 cells expressing miR-204 revealed changes in the expression of hundred cancer-related genes. Of these, we focused on the study of pro-angiogenic ANGPT1 and TGFβR2. Functional analysis using luciferase reporter and rescue assays confirmed that ANGPT1 and TGFβR2 are novel effectors downstream of miR-204. Accordingly, an inverse correlation between miR-204 and ANGPT1/TGFβR2 expression was found in breast tumors. Knockdown of TGFβR2, but not ANGPT1, impairs cell proliferation and migration whereas inhibition of both genes inhibits angiogenesis. Taken altogether, our findings reveal a novel role for miR-204/ANGPT1/TGFβR2 axis in tumor angiogenesis. We propose that therapeutic manipulation of miR-204 levels may represent a promising approach in breast cancer.

Abstract
SARI, also called as BATF2, belongs to the BATF family and has been implicated in cancer cell growth inhibition. However, the role and mechanism of SARI in tumour angiogenesis are elusive. Here we demonstrate that SARI deficiency facilitates AOM/DSS-induced colonic tumorigenesis in mice. We show that SARI is a novel inhibitor of colon tumour growth and angiogenesis in mice. Antibody array and HUVEC-related assays indicate that VEGF has an essential role in SARI-controlled inhibition of angiogenesis. Furthermore, Co-IP/PAGE/mass spectrometry indicates that SARI directly targets ceruloplasmin (Cp), and induces protease degradation of Cp, thereby inhibiting the activity of the HIF-1α/VEGF axis. Tissue microarray results indicate that SARI expression inversely correlates with poor clinical outcomes in colon cancer patients. Collectively, our results indicate that SARI is a potential target for therapy by inhibiting angiogenesis through the reduction of VEGF expression and is a prognostic indicator for patients with colon cancer.

Abstract
Gonadotropin signaling plays an indispensable role in ovarian cancer progression. We previously have demonstrated that thyrostimulin and thyroid-stimulating hormone receptor (TSHR), the most ancient glycoprotein hormone and receptor pair that evolved much earlier than the gonadotropin systems, co-exist in the ovary. However, whether thyrostimulin-driven TSHR activation contributes to ovarian cancer progression in a similar way to gonadotropin receptors has never been explored. In this study, we first found that TSHR is expressed in both rat normal ovarian surface epithelium and human epithelial ovarian cancers (EOCs). Using human NIH:OVCAR-3 as a cell model, we demonstrated that thyrostimulin promotes EOC cell proliferation as strongly as gonadotropins. Thyrostimulin treatment not only activated adenylyl cyclase and the subsequent PKA, MEK-ERK1/2 and PI3K-AKT signal cascades, but also trans-activated EGFR signaling. Signaling dissection using diverse inhibitors indicated that EOC cell proliferation driven by thyrostimulin-TSHR signaling is PKA independent, but does require the involvement of the MEK-ERK and PI3K-AKT signal cascades, which are activated mainly via the trans-activation of EGFR. Thus, not only have we proved that this ancient glycoprotein hormone system is involved in NIH:OVCAR-3 cell proliferation for the first time, but also that it may possibly become a novel oncotarget when studying ovarian cancer.

Abstract
Resistance to chemotherapy is among the most important issues in the management of ovarian cancer. Unlike cancer cells, which are heterogeneous as a result of remarkable genetic instability, stromal cells are considered relatively homogeneous. Thus, targeting the tumor microenvironment is an attractive approach for cancer therapy. Arguably, anti-vascular endothelial growth factor (anti-VEGF) therapies hold great promise, but their efficacy has been modest, likely owing to redundant and complementary angiogenic pathways. Components of platelet-derived growth factor (PDGF), fibroblast growth factor (FGF), epidermal growth factor (EGF), and other pathways may compensate for VEGF blockade and allow angiogenesis to occur despite anti-VEGF treatment. In addition, hypoxia induced by anti-angiogenesis therapy modifies signaling pathways in tumor and stromal cells, which induces resistance to therapy. Because of tumor cell heterogeneity and angiogenic pathway redundancy, combining cytotoxic and targeted therapies or combining therapies targeting different pathways can potentially overcome resistance. Although targeted therapy is showing promise, much more work is needed to maximize its impact, including the discovery of new targets and identification of individuals most likely to benefit from such therapies.

Abstract
Autophagy is a highly conservative cell behavior to keep the intracellular homeostasis and is frequently activated when cells encounter disgusting conditions, such as nutrition or growth factor deprive, hypoxia and cytotoxic agents. However, the precise role of autophagy under various conditions may be opposite, differ from protect cells survival to promote cells death, and the mechanism of this conditional-dependent role is still unclear. Anti-angiogenesis agents, such as bevacizumab, sorafenib and sunitinib, could reduce tumor microvascular density and increase tumor hypoxia, thus up-regulating autophagy activation of tumor cells, but the function of autophagy induced by anti-angiogenesis agents is still divergent and is considered to play a cytoprotective role in most cases. In this review, we mainly discuss the relationship between anti-angiogenesis therapy-induced hypoxia and autophagy, and pay special attention on the exact role of anti-angiogenesis agents induced autophagy in the process of anti-angiogenesis treatment.

Abstract
Late and recurrent stage ovarian cancer has a high mortality and low response rate to therapy beyond first line treatment. Although first line platinum/taxane based regimens have a satisfactory response rate eventually in most cases disease recurrence is common and second-line treatments are not curative. Delaying progression or recurrence is the main goal of current ongoing clinical studies by means of establishing an effective maintenance regimen with acceptable toxicity profile. Clearly, the persistence of dormant and drug-resistant cells after front-line treatments results in the inability to cure the disease. Over the past several years, the idea of prolongation of therapy for ovarian cancer has garnered clinical attention and academic debate. As a result of a greater understanding of the molecular pathways involved in carcinogenesis and tumor growth, a large number of potential therapeutic targets have been identified and drugs to block receptors, ligands or pathways are being developed. Currently, numerous clinical trials with targeted agents have just been completed or are ongoing involving patients achieving a complete or durable response after first-line and beyond the first line chemotherapy in order to evaluate the efficacy of different therapeutic approaches in terms of progression-free survival and overall survival.

Abstract
Targeting the tumor vasculature with anti-angiogenesis modalities is a bona fide validated approach that has complemented cancer treatment paradigms. Tumor vasculature antigens (TVA) can be immunologically targeted and offers multiple theoretical advantages that may enhance existing strategies against cancer. We focused on tumor endothelial marker 1 (TEM1/CD248) as a model TVA since it is broadly expressed on many different cancers. Our DNA-based vaccine approach demonstrated that CD248 can be effectively targeted immunologically; anti-tumor responses were generated in several mouse models; and CD8(+)/CD4(+) T cell responses were elicited against peptides derived from CD248 protein. Our work supports our contention that CD248 is a novel immunotherapeutic target for cancer treatment and highlights the efficient, safe and translatable use of DNA-based immunotherapy. We next briefly highlight ongoing investigations targeting CD248 with antibodies as a diagnostic imaging agent and as a therapeutic antibody in an early clinical trial. The optimal approach for generating effective DNA-based cancer vaccines for several tumor types may be a combinatorial approach that enhances immunogenicity such as combination with chemotherapy. Additional combination approaches are discussed and include those that alleviate the immunosuppressive tumor microenvironment induced by myeloid-derived suppressor cells and T regulatory cells. Targeting the tumor vasculature by CD248-based immunological modalities expands the armamentarium against cancer.

Abstract
Despite the development of a myriad of anticancer drugs that appeared promising in preclinical ovarian cancer animal models, they failed to predict efficacy in clinical testing. To improve the accuracy of preclinical testing of efficacy and toxicity, including pharmacokinetic and pharmacodynamic evaluations, a novel animal model was developed and characterized. In this study, murine ID8 (epithelial ovarian cancer [EOC]) cells as injected cell suspensions (ICS) and as intact cultured monolayer cell sheets (CS) were injected or surgically grafted, respectively, into the left ovarian bursa of 6-8 week-old, female C57BL/6 black mice and evaluated at 8 and 12 weeks after engraftment. Tumor volumes at 8 weeks were as follows: 30.712 ± 18.800 mm(3) versus 55.837 ± 10.711 mm(3) for ICS and CS, respectively, p = 0.0990 (n = 5). At 12 weeks, tumor volumes were 128.129 ± 44.018 mm(3) versus 283.953 ± 71.676 mm(3) for ICS and CS, respectively, p = 0.0112 (n = 5). The ovarian weights at 8 and 12 weeks were 0.02138 ± 0.01038 g versus 0.04954 ± 0.00667 g for ICS and CS, respectively (8 weeks), p = 0.00602 (n = 5); and 0.10594 ± 0.03043 g versus 0.39264 ± 0.09271 g for ICS and CS, respectively (12 weeks), p = 0.0008 (n = 5). These results confirm a significant accelerated tumorigenesis in CS-derived tumors compared with ICS-derived tumors when measured by tumor volume/time and ovarian weight/time. Furthermore, the CS-derived tumors closely replicated the metastatic spread found in human EOC and histopathological identity with the primary tumor of origin.

Abstract
Background We recently identified two robust ovarian cancer subtypes, defined by the expression of genes involved in angiogenesis, with significant differences in clinical outcome. To identify potential regulatory mechanisms that distinguish the subtypes we applied PANDA, a method that uses an integrative approach to model information flow in gene regulatory networks. Results We find distinct differences between networks that are active in the angiogenic and non-angiogenic subtypes, largely defined by a set of key transcription factors that, although previously reported to play a role in angiogenesis, are not strongly differentially-expressed between the subtypes. Our network analysis indicates that these factors are involved in the activation (or repression) of different genes in the two subtypes, resulting in differential expression of their network targets. Mechanisms mediating differences between subtypes include a previously unrecognized pro-angiogenic role for increased genome-wide DNA methylation and complex patterns of combinatorial regulation. Conclusions The models we develop require a shift in our interpretation of the driving factors in biological networks away from the genes themselves and toward their interactions. The observed regulatory changes between subtypes suggest therapeutic interventions that may help in the treatment of ovarian cancer.

Abstract
Ovarian cancer is a multifaceted and genomically complex disease and has emerged as leading cause of death among gynecological malignancies. Gold-standard treatment consisted of cytoreductive surgery and paclitaxel-carboplatin chemotherapy. Recently, promising results of randomized trials have definitively confirmed the importance of angiogenesis in oncogenesis and ovarian cancer behavior, by showing a significant prolongation of progression-free survival with the addiction of an angiogenesis inhibitor to standard treatment in the first and second line setting. Research over the years has sequentially provided a rapidly broadening signaling landscape and many drugs targeting different signaling pathways of angiogenesis have been developed and investigated. Recently accumulating scientific evidence has started to shed light on the efficacy of AMG 386, a new peptibody reported to neutralize the interaction between angiopoietins (Ang1/2) and their Tie2 receptors, thus representing a promising alternative, both in terms of efficacy and toxicity profile and is considerably under investigation. The aim of this review is to summarize the recent researches and clinical progresses of AMG 386 as a novel target agent in ovarian cancer.

Abstract
Object: To assess the effects of lymphovascular space invasion (LVSI) on cancer recurrence and survival in patients with primary epithelial ovarian cancer. Methods: A retrospective study was conducted of patients with stage I-IV primary epithelial ovarian cancer who underwent cytoreductive surgery. LVSI is defined as the presence of tumor cells within an endothelium-lined space, and the patients' pathologic slides were reevaluated by gynecological pathologists. Survival analysis was performed to compare risk factors. Results: A total of 492 patients were included in the analysis. The incidence of LVSI was 58.5% in our cohort (288 cases), and it was significantly associated with advanced stage, high-grade serous histology, high grade, and lymph node metastasis (P<0.001). Kaplan-Meier analysis demonstrated that LVSI was only correlated with decreased PFS (5-year rate, 39% vs. 66%, P<0.001) and OS (5-year rate, 44% vs. 78%, P<0.001) in patients at early stage but not at advanced stage (5-year rate, PFS: 14% vs. 11%, P<0.001; OS: 29% vs. 29%, P=0.141). Multivariate analysis showed that LVSI remained a significant variable with PFS and OS in early-stage ovarian cancer (PFS: HR 2.29, 95% CI 1.45-3.57; OS: HR 2.20, 95% CI 1.59-3.44, both P<0.001). Conclusion: LVSI is an independent predictor of progression and survival in patients with primary epithelial ovarian cancer at early stage but not at advanced stage.

Abstract
PURPOSE Zoledronic acid is being increasingly recognized for its antitumor properties, but the underlying functions are not well understood. In this study, we hypothesized that zoledronic acid inhibits ovarian cancer angiogenesis preventing Rac1 activation. EXPERIMENTAL DESIGN The biologic effects of zoledronic acid were examined using a series of in vitro [cell invasion, cytokine production, Rac1 activation, reverse-phase protein array, and in vivo (orthotopic mouse models)] experiments. RESULTS There was significant inhibition of ovarian cancer (HeyA8-MDR and OVCAR-5) cell invasion as well as reduced production of proangiogenic cytokines in response to zoledronic acid treatment. Furthermore, zoledronic acid inactivated Rac1 and decreased the levels of Pak1/p38/matrix metalloproteinase-2 in ovarian cancer cells. In vivo, zoledronic acid reduced tumor growth, angiogenesis, and cell proliferation and inactivated Rac1 in both HeyA8-MDR and OVCAR-5 models. These in vivo antitumor effects were enhanced in both models when zoledronic acid was combined with nab-paclitaxel. CONCLUSIONS Zoledronic acid has robust antitumor and antiangiogenic activity and merits further clinical development as ovarian cancer treatment.

Abstract
Vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) are important proangiogenic factors in tumor procession. The autocrine and paracrine bFGF and the VEGF in tumor tissue can promote tumor angiogenesis, tumor growth, and metastasis. A VEGF/bFGF Complex Peptide (VBP3) was designed on the basis of epitope peptides from both VEGF and bFGF to elicit in vivo production of anti-bFGF and anti-VEGF antibodies. In this study, we reported on the production of recombinant VBP3 using high cell density fermentation. Fed-batch fermentation for recombinant VBP3 production was conducted, and the production procedure was optimized in a 10-L fermentor. The fraction of soluble VBP3 protein obtained reached 78% of total recombinant protein output under fed-batch fermentation. Purified recombinant VBP3 could inhibit tumor cell proliferation in vitro and stimulate C57BL/6 mice to produce high titer anti-VEGF and anti-bFGF antibodies in vivo. A melanoma-grafted mouse model and an immunohistochemistry assay showed that tumor growth and tumor angiogenesis were significantly inhibited in VBP3-vaccinated mice. These results demonstrated that soluble recombinant VBP3 could be produced by large-scale fermentation, and the product, with good immunogenicity, elicited production of high-titer anti-bFGF and anti-VEGF antibodies, which could be used as a therapeutic tumor vaccine to inhibit tumor angiogenesis and tumor growth.

Abstract
Antiangiogenic agents have demonstrated improved progression-free survival in women with primary and recurrent epithelial ovarian cancer (EOC). Biomarkers that predict outcomes in patients treated with antiangiogenic agents are being investigated to rationally direct therapy for women most likely to benefit from these agents. Among the most promising plasma-based biomarkers are vascular endothelial growth factor (VEGF)-A, fibroblast growth factor, platelet-derived growth factor, angiopoietin-2, and VEGF receptor-2. While these biomarkers have been correlated with prognosis, they have not been shown to predict benefit, specifically from anti-VEGF therapy, highlighting the need for alternative biomarkers, including molecular and clinical factors, which may be predictive of outcome in women with ovarian cancer treated with antiangiogenic agents. Biomarkers are currently being investigated as secondary outcomes in several ongoing phase II and phase III clinical trials of antiangiogenic agents in patients with EOC. Molecular techniques, such as microarray analyses, and imaging techniques, such as dynamic contrast-enhanced magnetic resonance imaging, positron emission tomography, and single photon emission computed tomography, are also being explored in this field. In this review, we provide a comprehensive overview of current biomarker research, with an emphasis on angiogenic biomarkers associated with EOC.

Abstract
Targeting angiogenesis is proving to be a successful approach in the management of ovarian cancer. The vascular endothelial growth factor inhibitor, bevacizumab, is the first angiogenesis inhibitor to have shown a significant progression-free survival advantage in the Phase III setting. There is now evidence supporting the use of bevacizumab in combination with chemotherapy for first-line and relapsed (platinum-sensitive and resistant) ovarian cancer. In this review, we summarize the positive Phase III trial (OCEANS [Ovarian Cancer Study Comparing Efficacy and Safety of Chemotherapy and Anti-Angiogenic Therapy in Platinum-Sensitive Recurrent Disease]) that led to European Medicines Agency approval of bevacizumab in platinum-sensitive first relapse and discuss the best use of the drug in this disease.

The expression of VEGF and Dll4/Notch pathway molecules in ovarian cancer. Clin Chim Acta 2014; 436:243-8. [PMID: 24949865 DOI: 10.1016/j.cca.2014.06.005] [Citation(s) in RCA: 27] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2013] [Revised: 05/17/2014] [Accepted: 06/07/2014] [Indexed: 11/24/2022]
Abstract
BACKGROUND VEGF and Dll4/Notch pathways play important roles in tumor angiogenesis. The purpose of this study is to investigate the expression of these two pathway molecules in ovarian cancer and their possible relationships in carcinogenesis. METHODS Twenty-eight specimens of human ovarian carcinoma, 18 of benign ovarian and 20 of healthy ovarian tissues were subjected to immunohistochemical analysis for VEGF, VEGFR1, and VEGFR2, Dll4, Notch1, and Notch3 expression. Microvessel density (MVD) was evaluated by counting the number of CD34-stained microvessels in each pathologic specimen. RESULTS The expression of VEGF, VEGFR1, Dll4, Notch1, or Notch3 in ovarian tumor tissues was higher than that in normal ovary tissues as well as that in benign ovarian tumor tissues (P<0.05). In the tumor tissues, Dll4 was positively correlated with VEGFR1 expression and Notch1 was positively associated with VEGFR2 and MVD. Moreover, VEGFR2 expression was positively associated with ascites and distant metastasis (R=0.401, P=0.034). CONCLUSIONS Dll4 represents a potential biomarker and therapeutic target for ovarian angiogenesis. VEGFR2 is significantly related to ovarian metastasis and invasion. Therefore testing the key molecules of these two pathways expression may have some diagnostic and prognostic value for ovarian cancer.

Abstract
Epithelial ovarian cancer is the most lethal type of gynecologic malignancy. Sixty percent of women who are diagnosed with ovarian cancer present with advanced-stage disease that involves the peritoneal cavity and these patients have a 5-year survival rate of less than 30%. For more than two decades, tumor-debulking surgery followed by platinum-taxane combination chemotherapy has remained the conventional first-line treatment of ovarian cancer. Although the initial response rate is 70%-80%, most patients with advanced-stage ovarian cancer eventually relapse and succumb to recurrent chemoresistant disease. A number of molecular aberrations that drive tumor progression have been identified in ovarian cancer cells and intensive efforts have focused on developing therapeutic agents that target these aberrations. However, increasing evidence indicates that reciprocal interactions between tumor cells and various types of stromal cells also play important roles in driving ovarian tumor progression and that these stromal cells represent attractive therapeutic targets. Unlike tumor cells, stromal cells within the tumor microenvironment are in general genetically stable and are therefore less likely to become resistant to therapy. This concise review discusses the biological significance of the cross-talk between ovarian cancer cells and three major types of stromal cells (endothelial cells, fibroblasts, macrophages) and the development of new-generation therapies that target the ovarian tumor microenvironment.

Abstract
The expression of 15-lipoxygenase-1 (15-LOX-1) is downregulated in colon cancer and other major cancers, and 15-LOX-1 reexpression in cancer cells suppresses colonic tumorigenesis. Various lines of evidence indicate that 15-LOX-1 expression suppresses premetastatic stages of colonic tumorigenesis; nevertheless, the role of 15-LOX-1 loss of expression in cancer epithelial cells in metastases continues to be debated. Hypoxia, a common feature of the cancer microenvironment, promotes prometastatic mechanisms such as the upregulation of hypoxia-inducible factor (HIF)-1α, a transcriptional master regulator that enhances cancer cell metastatic potential, angiogenesis, and tumor cell invasion and migration. We have, therefore, tested whether restoring 15-LOX-1 in colon cancer cells affects cancer cells' hypoxia response that promotes metastasis. We found that 15-LOX-1 reexpression in HCT116, HT29LMM, and LoVo colon cancer cells inhibited survival, vascular endothelial growth factor (VEGF) expression, angiogenesis, cancer cell migration and invasion, and HIF-1α protein expression and stability under hypoxia. These findings demonstrate that 15-LOX-1 expression loss in cancer cells promotes metastasis and that therapeutically targeting ubiquitous 15-LOX-1 loss in cancer cells has the potential to suppress metastasis.
