Abstract
Cancer immunotherapy harnesses the immune system to combat cancer, yet tumors often evade immune surveillance through immunosuppressive cells. Herein, we report an organic semiconducting sono-metallo-detonated immunobomb (SMIB) to spatiotemporally tame immunosuppressive cells in situ. SMIB consists of an amphiphilic semiconducting polymer (SP) with a repeatable thiophene-based Schiff base serving as an iron ion chelator (Fe3+). SMIB increases sonochemical activity through iron chelation and reduces immunosuppressive cell differentiation with metals and sonochemicals, thereby decreasing the irradiation dose. Upon ultrasound irradiation, SMIB acts as a sono-metallo-detonated immunobomb and inhibits Tregs via the mTOR pathway and M2 macrophage polarization through GPX4 regulation. Ultrasensitized sono-generated reactive oxygen species also promote activation of antigen-presenting cells in deep solid tumors (1 cm), resulting in cytotoxic T cell infiltration and enhanced antitumor efficacy. This platform provides a versatile approach for synergistic sono- and metalloregulation of immunosuppressive cells in situ.

Ubachs J, Ziemons J, Minis‐Rutten IJ, Kruitwagen RF, Kleijnen J, Lambrechts S, Olde Damink SW, Rensen SS, Van Gorp T. Sarcopenia and ovarian cancer survival: a systematic review and meta-analysis. J Cachexia Sarcopenia Muscle 2019; 10:1165-1174. [PMID: 31389674 PMCID: PMC6903439 DOI: 10.1002/jcsm.12468] [Citation(s) in RCA: 94] [Impact Index Per Article: 18.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/15/2019] [Revised: 05/24/2019] [Accepted: 06/12/2019] [Indexed: 12/22/2022] Open
Abstract
BACKGROUND Sarcopenia is the loss of skeletal muscle mass and function that occurs with advancing age and certain diseases. It is thought to have a negative impact on survival in cancer patients. Routine computed tomography imaging is often used to quantify skeletal muscle in cancer patients. Sarcopenia is defined by a low skeletal muscle index (SMI). Skeletal muscle radiation attenuation (SMRA) is used to define muscle quality. The primary aim of this meta-analysis was to study the association between sarcopenia or SMRA and overall survival (OS) or complications in patients with ovarian cancer. METHODS Medline, Embase, CINAHL, and PEDro databases were searched from inception to 15 February 2019. Studies evaluating the prognostic effect of SMI and SMRA on ovarian cancer survival or surgical complications were included. Risk of bias and study quality were evaluated with the Quality in Prognosis Studies Instrument (QUIPS) according to the modified Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework. RESULTS The search strategy yielded 4262 hits in all four databases combined. Ten and eight studies were included for qualitative and quantitative analysis, respectively. Meta-analysis revealed a significant association between the SMI and OS [0.007; hazard ratio (HR): 1.11, 95% confidence interval (CI): 1.03-1.20]. SMRA was also significantly associated with OS (P < 0.001; HR: 1.14, 95% CI: 1.08-1.20). Association between the SMI and surgical complications had borderline statistical significance (0.05; HR: 1.23, 95% CI: 1.00-1.52). The risk of bias assessed with QUIPS was high in all studies. The quality of the evidence was very low. CONCLUSIONS Whereas our meta-analysis indicated that a low SMI and low SMRA are associated with survival in ovarian cancer patients, the low quality of the source data precludes drawing definitive conclusions.

Onco Targets Ther 2019; 12:9697-9706. [PMID: 32009802 PMCID: PMC6859960 DOI: 10.2147/ott.s209757] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2019] [Accepted: 09/24/2019] [Indexed: 12/24/2022] Open
Abstract
PURPOSE This study aimed to explore the effects of interferon-γ inducible protein 10 (IP10) and complementarity-determining region 3 (CDR3) of T cells receptor on ovarian cancer cells and the involved mechanisms. METHODS IP10 and CDR3 were linked with single-chain antibody (scfv) and exotoxin gene muton of Pseudomonas aeruginosa (PE40) to construct IP10-CDR3scfv and IP10-CDR3-PE40scfv. Then, we constructed pcDNA3.1-IP10-CDR3scfv and pcDNA3.1-IP10-CDR3-PE40scfv plasmids which were proved by HindIII/EcoRI digestion. SKOV3 cells and HOSEpiC cells were incubated with fluorescein isothiocyanate (FITC) labeled IP10-CDR3scfv and IP10-CDR3-PE40scfv proteins and protein levels were examined by flow cytometry. After gene transfection, SKOV3 cells were divided into four groups: Control, pcDNA3.1(+) negative control (NC) (pcDNA3.1(+) NC transfection), IP10-CDR3scfv (IP10-CDR3scfv transfection) and IP10-CDR3-PE40scfv (IP10-CDR3-PE40scfv transfection). Levels of IP10, CDR3, Caspase-3, cleaved Caspase-3 and Bcl-2 were determined by RT-PCR and Western blot. Cell viability and apoptosis were investigated by CCK-8 assay and Annexin V-FITC/PI assay, respectively. RESULTS The levels of FITC-labeled IP10-CDR3scfv and IP10-CDR3-PE40scfv proteins in the SKOV3+IP10-CDR3scfv group and the SKOV3+IP10-CDR3-PE40scfv group were remarkably higher than that in the SKOV3 group (P<0.05). So was the HOSEpiC related groups. There was no obvious difference in the levels of IP10, CDR3, Caspase-3, cleaved Caspase-3 and Bcl-2 between the control group and the pcDNA3.1(+) NC group. However, compared with the control group, the levels of Caspase-3 and Bcl-2 were reduced notably and the levels of IP10, CDR3 and cleaved Caspase-3 were elevated sharply in the IP10-CDR3scfv and IP10-CDR3-PE40scfv groups (P<0.05). The control group and the pcDNA3.1(+) NC group demonstrated similar cell viability and apoptosis. However, compared with the control group, cell viability in the IP10-CDR3scfv and IP10-CDR3-PE40scfv groups decreased significantly and cell apoptosis increased (P<0.05). CONCLUSION IP10-CDR3 could reduce the viability and induce the apoptosis of ovarian cancer cells by down-regulating the expression of Bcl-2 and Caspase-3.

Abstract
Due to the success of chimeric antigen receptors (CARs) in hematological tumors, CARs are also being studied to treat solid tumors. Improving the ability of CARs to penetrate solid tumor tissues is one of the biggest challenges. As the most malignant cancer of the female reproductive system, the survival rate of ovarian cancer has not been significantly improved by traditional therapy methods; therefore, it is necessary to develop new therapeutic targets and new immunotherapy methods for ovarian cancer. UPAR is a glysocylphosphatidylinositol (GPI) anchoring membrane protein that is differentially expressed in normal tissues and ovarian cancer tissues. It has been shown that uPAR up-regulation promotes tumor development, proliferation, invasion, and metastasis, and uPAR is also up-regulated in tumor matrix components. In our study, CARs were designed using the natural ligand binding fragment of uPAR for ovarian cancer.

Abstract
RNA viruses have been subjected to substantial engineering efforts to support gene therapy applications and vaccine development. Typically, retroviruses, lentiviruses, alphaviruses, flaviviruses rhabdoviruses, measles viruses, Newcastle disease viruses, and picornaviruses have been employed as expression vectors for treatment of various diseases including different types of cancers, hemophilia, and infectious diseases. Moreover, vaccination with viral vectors has evaluated immunogenicity against infectious agents and protection against challenges with pathogenic organisms. Several preclinical studies in animal models have confirmed both immune responses and protection against lethal challenges. Similarly, administration of RNA viral vectors in animals implanted with tumor xenografts resulted in tumor regression and prolonged survival, and in some cases complete tumor clearance. Based on preclinical results, clinical trials have been conducted to establish the safety of RNA virus delivery. Moreover, stem cell-based lentiviral therapy provided life-long production of factor VIII potentially generating a cure for hemophilia A. Several clinical trials on cancer patients have generated anti-tumor activity, prolonged survival, and even progression-free survival.

Abstract
Immunotherapy has emerged as one of the most promising approaches for ovarian cancer treatment. The tumor microenvironment (TME) is a key factor to consider when stimulating antitumoral responses as it consists largely of tumor promoting immunosuppressive cell types that attenuate antitumor immunity. As our understanding of the determinants of the TME composition grows, we have begun to appreciate the need to address both inter- and intra-tumor heterogeneity, mutation/neoantigen burden, immune landscape, and stromal cell contributions. The majority of immunotherapy studies in ovarian cancer have been performed using the well-characterized murine ID8 ovarian carcinoma model. Numerous other animal models of ovarian cancer exist, but have been underutilized because of their narrow initial characterizations in this context. Here, we describe animal models that may be untapped resources for the immunotherapy field because of their shared genomic alterations and histopathology with human ovarian cancer. We also shed light on the strengths and limitations of these models, and the knowledge gaps that need to be addressed to enhance the utility of preclinical models for testing novel immunotherapeutic approaches.
