Araújo NM, Rubio IGS, Toneto NPA, Morale MG, Tamura RE. The use of adenoviral vectors in gene therapy and vaccine approaches. Genet Mol Biol 2022; 45:e20220079. [PMID: 36206378 PMCID: PMC9543183 DOI: 10.1590/1678-4685-gmb-2022-0079] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2022] [Accepted: 07/12/2022] [Indexed: 11/04/2022] Open
Abstract
Adenovirus was first identified in the 1950s and since then this pathogenic group
of viruses has been explored and transformed into a genetic transfer vehicle.
Modification or deletion of few genes are necessary to transform it into a
conditionally or non-replicative vector, creating a versatile tool capable of
transducing different tissues and inducing high levels of transgene expression.
In the early years of vector development, the application in monogenic diseases
faced several hurdles, including short-term gene expression and even a fatality.
On the other hand, an adenoviral delivery strategy for treatment of cancer was
the first approved gene therapy product. There is an increasing interest in
expressing transgenes with therapeutic potential targeting the cancer hallmarks,
inhibiting metastasis, inducing cancer cell death or modulating the immune
system to attack the tumor cells. Replicative adenovirus as vaccines may be even
older and date to a few years of its discovery, application of non-replicative
adenovirus for vaccination against different microorganisms has been
investigated, but only recently, it demonstrated its full potential being one of
the leading vaccination tools for COVID-19. This is not a new vector nor a new
technology, but the result of decades of careful and intense work in this
field.

Adoptive cell therapy of patient-derived renal cell carcinoma xenograft model with IL-15-induced γδT cells. Med Oncol 2021; 38:30. [PMID: 33598783 DOI: 10.1007/s12032-021-01474-1] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2020] [Accepted: 01/26/2021] [Indexed: 12/13/2022]
Abstract
Adoptive transfer of γδ T cells is an attractive approach for cell-based immunotherapy in treatment of renal cell carcinoma (RCC). Interleukin-15 (IL-15) is the key physiological cytokine that regulates γδ T cell differentiation, proliferation and survival. In this work, we determined that IL-15 have the capacity to enhance the anti-tumoral functions of γδ T cells. IL-15 can induce the upregulation of cytotoxicity-associated molecules on the γδ T cell surface, incite γδ T cell proliferation and decrease apoptosis. Moreover, the enhanced cytotoxicity of IL-15-induced γδ T cell was dependent on the interaction of NKG2D and MICA. Most importantly, we found that IL-15-induced γδ T cells effectively suppressed the tumor growth in vivo and prolonged the survival time of RCC-bearing patient‑derived xenograft (PDX) mice. These results are important for the prospective use of γδ T cells in clinical practice when designing novel cell-based immunotherapies against RCC.

[PMID: 32791096 DOI: 10.1016/j.neulet.2020.135289] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2019] [Revised: 07/26/2020] [Accepted: 07/30/2020] [Indexed: 12/19/2022]
Abstract
This study explored the regulatory role of microRNA-1271 (miR-1271) in glioblastoma multiforme (GBM) proliferation and invasion via calcium/calmodulin-dependent protein kinase 2 (CaMKK2). MiR-1271 and CaMKK2 expression were quantified in normal human astrocyte cells, GBM cell lines, and low- and high-grade glioma tissues. MKI67 expression in GBM cells was measured using quantitative real-time polymerase chain reaction. The target relationship between miR-1271 and the CAMKK2 gene was confirmed using the luciferase reporter assay. MTT and Transwell assays were used to analyze the role of miR-1271 and CAMKK2 in cell proliferation and invasion. Finally, CaMKK2 expression and AKT phosphorylation were detected by western blotting. MiR-1271 was significantly downregulated in high-grade glioma tissues and GBM cell lines. Conversely, CAMKK2 mRNA expression was upregulated in high-grade glioma tissues and GBM cell lines. We observed that miR-1271 directly targeted the 3'-untranslated region of CAMKK2, indicating an inverse relationship with miR-1271. Overexpressing miR-1271 inhibited GBM cell proliferation and invasion, whereas inhibiting miR-1271 increased cell proliferation and invasion. Silencing CAMKK2 expression also inhibited GBM cell proliferation and invasion. Furthermore, overexpressing miR-1271 inhibited AKT phosphorylation and MKI67 mRNA expression by targeting CAMKK2. These results indicate that miR-1271 regulates GBM cell proliferation and invasion, and that these effects involve directly targeting the CAMKK2 gene. Therefore, miR-1271 may serve as a new therapeutic target for developing GBM treatments.

Absent in melanoma 2 enhances anti-tumour effects of CAIX promotor controlled conditionally replicative adenovirus in renal cancer. J Cell Mol Med 2020; 24:10744-10755. [PMID: 32725966 PMCID: PMC7521288 DOI: 10.1111/jcmm.15697] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2020] [Revised: 07/01/2020] [Accepted: 07/09/2020] [Indexed: 12/28/2022] Open
Abstract
Conditionally replicative adenoviruses (CRAds) were promising approach for solid tumour treatment, but its oncolytic efficiency and toxicity are still not satisfactory for further clinical application. Here, we developed the CAIX promotor (CAIXpromotor)‐controlled CRAd armed with a tumour suppressor absent in melanoma 2 (AIM2) to enhance its oncolytic potency. The CAIXpromotor‐AIM2 adenoviruses (Ad‐CAIXpromotor‐AIM2) could efficiently express E1A and AIM2 in renal cancer cells. Compared with Ad‐CAIXpromotor, Ad‐CAIXpromotor‐AIM2 significantly inhibited cell proliferation and enhanced cell apoptosis and cell killing, thus resulting in the oncolytic efficiency in 786‐O cells or OSRC‐2 cells. To explore the therapeutic effect, various Ads were intratumourally injected into OSRC‐2‐xenograft mice. The tumour growth was remarkably inhibited in Ad‐CAIXpromotor‐AIM2‐treated group as demonstrated by reduced tumour volume and weight with a low toxicity. The inflammasome inhibitor YVAD‐CMK resulted in the reduction of anti‐tumour activity by Ad‐CAIXpromotor‐AIM2 in vitro or in vivo, suggesting that inflammasome activation response was required for the enhanced therapeutic efficiency. Furthermore, lung metastasis of renal cancer mice was also suppressed by Ad‐CAIXpromotor‐AIM2 treatment accompanied by the decreased tumour fossil in lung tissues. These results indicated that the tumour‐specific Ad‐CAIXpromotor‐AIM2 could be applied for human renal cancer therapy. The therapeutic strategy of AIM2‐based CRAds could be a potential and promising approach for the therapy of primary solid or metastasis tumours.

Abstract
As part of oncolytic virotherapy to treat cancer, oncolytic viruses (OVs) can selectively infect tumor cells to promote oncolysis of cancer cells, local immunological reactions, and systemic antitumor immunity with minimal toxicity to normal tissues. The immunostimulatory properties of OVs provide enormous benefits for the treatment of cancer. A variety of OVs, including genetically engineered and natural viruses, have shown promise in preclinical models and clinical studies. In 2005, the China Food and Drug Administration approved its first OV drug, Oncorine (H101), for treatment of advanced head and neck cancer. To explore new treatment strategies, >200 recombinant or natural OVs are undergoing in-depth investigation in China, and >250 oncolytic virotherapy-related reports from the OV community in China have been published in the past 5 years. These studies investigated a variety of exogenous genes and combination therapeutic strategies to enhance the treatment effects of OVs. To date, five clinical trials covering four OV agents (Oncorine, OrienX010, KH901, and H103) are ongoing, and additional OV agents are awaiting approval for clinical trials in China. Overall, this research emphasizes that combination therapy, especially tumor immunotherapy coupled with effective system administration strategies, can promote the development of oncolytic virotherapies. This article focuses on studies that were carried out in China in order to give an overview of the past, present, and future of oncolytic virotherapy in China.

Abstract
Newer treatment strategy based on proliferative nuclear marker Ki-67 targeted therapy holds promise for prioritized/personalized treatment options with regard to improved survival and outcome in patients with renal cancer. Over the past decade, the importance of Ki-67 in prognosis of breast cancer has been widely studied, however very few studies and literatures are available in the context of renal cancer which has an increasing incidence internationally. The focus of this present review is to fill the gaps pertaining to its prognosis and management with newly understood mechanisms of targeted interventions. Recent breakthrough discoveries have highlighted the correlation of Ki-67 expression to stage and metastatic potential in renal tumours. A better understanding of molecular structure and different protein domains along with its regulation will provide evidence for precise target thereby controlling the proliferation rate correlated with decrease in the Ki-67 protein levels. Therapies targeting Ki-67 is still in the preclinical stage, besides its diagnostic and/or prognostic significance, a better understanding of targeted strategical studies is required for extrapolation to the clinical use. Current understanding of the associated molecular pathways and the precise role of Ki-67 could streamline the basis for predicting renal cancer outcome.

Abstract
The small-interfering RNAs (siRNAs) have been employed to knockdown the expression of cancer-associated genes and shown some promise in cancer therapy. However, synthetic siRNA duplexes or plasmid mediated delivery of siRNAs have several problems, such as short half-life, low transfection efficiency and cytotoxicity associated with transfection. Conditionally replicating adenovirus (CRAds) as the delivery vector for short hairpin RNAs (shRNAs) could overcome these limitations and have shown augmented anti-tumor effects in experimental studies and preclinical trials. In this review, we summarize recent progress in the development of CRAds-shRNA for cancer treatment. Combination of CRAds-shRNA with chemotherapeutics, radiation, dendritic cells, monoclonal antibodies and small-molecule inhibitors will be necessary to eradicate cancer cells and cancer stem cells and achieve superior outcomes. The use of CRAd platform for efficient delivery of shRNAs and foreign genes will open a new avenue for cancer therapy.

Abstract
B-cell acute lymphoblastic leukemia (B-ALL) is a rare heterogeneous disease characterized by a block in lymphoid differentiation and a rapid clonal expansion of immature, non-functioning B cells. Adult B-ALL patients have a poor prognosis with less than 50% chance of survival after five years and a high relapse rate after allogeneic haematopoietic stem cell transplantation. Novel treatment approaches are required to improve the outcome for patients and the identification of B-ALL specific antigens are essential for the development of targeted immunotherapeutic treatments. We examined twelve potential target antigens for the immunotherapy of adult B-ALL. RT-PCR indicated that only survivin and WT1 were expressed in B-ALL patient samples (7/11 and 6/11, respectively) but not normal donor control samples (0/8). Real-time quantitative (RQ)-PCR showed that survivin was the only antigen whose transcript exhibited significantly higher expression in the B-ALL samples (n = 10) compared with healthy controls (n = 4)(p = 0.015). Immunolabelling detected SSX2, SSX2IP, survivin and WT1 protein expression in all ten B-ALL samples examined, but survivin was not detectable in healthy volunteer samples. To determine whether these findings were supported by the analyses of a larger cohort of patient samples, we performed metadata analysis on an already published microarray dataset. We found that only survivin was significantly over-expressed in B-ALL patients (n = 215) compared to healthy B-cell controls (n = 12)(p = 0.013). We have shown that survivin is frequently transcribed and translated in adult B-ALL, but not healthy donor samples, suggesting this may be a promising target patient group for survivin-mediated immunotherapy.

Abstract
BACKGROUND Conditionally replicative oncolytic adenoviruses (CRAds) display significant anti-tumor effects. However, the traditional adenovirus of serotype 5 (Ad5) entering cancer cells via coxsackie virus and adenovirus receptor (CAR) can't be utilized for bladder cancer with low expression of CAR, which limits the application of Ad5. METHODS We utilized Ad5/F11p containing the chimeric fiber gene encoding the Ad5 fiber tail domain and Ad11p fiber shaft and knob domains to construct bladder cancer-specific chimeric type viruses Ad5/F11p-PSCAE-UPII-E1A, which can infect bladder cancer cells mediated by CD46 molecule. We carried out series of experiments in vitro to research anti-tumor effect of Ad5/F11p-PSCAE-UPII-E1A and the interaction in combination with cisplatin. RESULTS The results demonstrated Ad5/F11p-PSCAE-UPII-E1A could infect bladder cancer cells (T24, EJ and 5637) in a CAR-independent way, and exert anti-tumor effect by blocking the cancer cells in G1 phase and inducing apoptosis. Ad5/F11p-PSCAE-UPII-E1A plus cisplatin enhanced the anti-proliferative effect and increased the number of apoptotic cells compared with viruses or cisplatin alone. Ad5/F11p-PSCAE-UPII-E1A plus cisplatin could upregulate the proteins expression of p53, Bax, and cleaved caspase-3, and downregulated Bcl-2 protein expression in T24, EJ and 5637 cells. CONCLUSION We constructed a bladder cancer-specific oncolytic adenovirus and provided new combination treatment strategies for bladder cancer.

Abstract
ASBTARCT Adenoviruses mediated cancer gene therapies are widely investigated and show a promising effect on cancer treatment. However, efficient gene transfer varies among different cancer cell lines based on the expression of coxsakie adenovirus receptor (CAR). Hep27, a member of dehydrogenase/reductase (SDR) family, can bind to Mdm2, resulting in the attenuation of Mdm2-mediated p53 degradation. Here we constructed a fiber chimeric adenovirus carrying hep27 gene (F5/35-ZD55-Hep27), in which the fiber protein of 5-serotype adenovirus (Ad5) was substituted by that of 35-serotype adenovirus (Ad35), aiming to facilitate the infection for renal cancer cells and develop the role of hep27 in cancer therapy. We evaluated the CAR and CD46 (a membrane cofactor protein for Ad35) expression in four kinds of renal cancer cells and assessed the relationship between receptors and infection efficiency. 5/35 fiber-modified adenovirus had a much promising infectivity compared with Ad5-based vector in renal cancer cells. F5/35-ZD55-Hep27 had enhanced antitumor activity against human renal cancer cells compared to the other groups. Further, hep27 mediated p53 and cleaved-PARP upregulation and mdm2 downregulation was involved and caused increased apoptosis. Moreover, F5/35-ZD55-Hep27 significantly suppressed tumor growth in subcutaneous renal cancer cell xenograft models. Our data demonstrated that 5/35 fiber-modified adenovirus F5/35-ZD55-Hep27 transferred into renal cancers efficiently and increased p53 to induce cancer cell apoptosis. Thus 5/35 fiber-modified adenoviral vector F5/35-ZD55-Hep27 might a promising vector and antitumor reagent for renal cancer gene therapy.

Abstract
Renal cell carcinoma is the most frequent kidney malignancy and patients with metastatic disease have a poor prognosis. Suppressed apoptosis and marked invasiveness are distinctive features of renal cell carcinoma. In the present study, a dual‑regulated oncolytic adenovirus expressing the interluekin (IL)‑24 gene (Ki67‑ZD55‑IL‑24) was constructed utilizing the Ki67 promoter to replace the native viral promoter of the E1A gene. Whether the combination of Ki67‑ZD55‑IL‑24‑mediated gene virotherapy and radiotherapy produced increased cytotoxicity in renal cell carcinoma cells via mitochondrial apoptotic cell death was investigated. The data indicated that this novel strategy has the potential to be further developed into an effective approach to treat renal cell carcinoma. The results showed that the combination of Ki67‑ZD55‑IL‑24 and radiotherapy significantly enhanced anti‑tumour activity via increasing the induction of apoptosis in melanoma cells compared with the other agents.

Abstract
The expression of Ki67 is strongly associated with tumor cell proliferation and growth, and is widely used in routine pathological investigation as a proliferation marker. The nuclear protein Ki67 (pKi67) is an established prognostic and predictive indicator for the assessment of biopsies from patients with cancer. Clinically, pKi67 has been shown to correlate with metastasis and the clinical stage of tumors. In addition, it has been shown that Ki67 expression is significantly higher malignant tissues with poorly differentiated tumor cells, as compared with normal tissue. According to its predictive role, pKi67 expression identifies subpopulations of patients who are more likely to respond to a given therapy. The Ki67 labeling index is an independent prognostic factor for survival rate, which includes all stages and grade categories. There is a correlation between the ratio of Ki67‑positive malignant cells and patient survival. It has been shown that blocking of Ki67 either by microinjection of antibodies or through the use of antisense oligonucleotides leads to the arrest of cell proliferation. Specifically, antisense oligonucleotides and antibodies against pKi67 have been shown to inhibit the progression of the cell cycle. The Ki67 protein is well characterized at the molecular level and is extensively used as a prognostic and predictive marker for cancer diagnosis and treatment. Increasing evidence indicates that Ki67 may be an effective target in cancer therapy. It therefore merits further development, including testing in more sophisticated in vitro and appropriate in vivo models. This review provides an overview of recent advances in this field.

Abstract
RNA interference has been proven to be a powerful tool for gene knockdown. Our previous study demonstrated that a Ki67 shRNA carried by an adenovirus reduced Ki67 expression. In this study, we constructed novel oncolytic adenoviruses in which the Ki67 core promoter drove expression of the E1A gene. These adenoviruses were equipped with either a Ki67 small interfering RNA (siRNA), a human telomerase reverse transcriptase (hTERT) siRNA or a double siRNA targeting Ki67 and hTERT. We identified the antitumor activities of oncolytic adenoviruses in 3 renal cancer cell lines, human normal renal tube cell HK-2 and also in nude mice bearing KETR-3-xenografted tumors. Our results showed that these oncolytic adenoviruses, especially Ki67-ZXC2-double siRNA, could effectively induce silencing of the Ki67 and hTERT genes, allow efficient viral replication and induce significant apoptosis of renal cancer cells in vitro and in nude mice. We concluded that a dual siRNA mediated by oncolytic virotherapy could be an effective strategy for cancer gene therapy.

Abstract
Gene therapy and antibody approaches are crucial auxiliary strategies for hepatocellular carcinoma (HCC) treatment. Previously, we established a survivin promoter-regulated oncolytic adenovirus that has inhibitory effect on HCC growth. The human sulfatase-1 (hSulf-1) gene can suppress the growth factor signaling pathways, then inhibit the proliferation of cancer cells and enhance cellular sensitivity to radiotherapy and chemotherapy. I(131)-metuximab (I(131)-mab) is a monoclonal anti-HCC antibody that conjugated to I(131) and specifically recognizes the HAb18G/CD147 antigen on HCC cells. To integrate the oncolytic adenovirus-based gene therapy and the I(131)-mab-based radioimmunotherapy, this study combined the CArG element of early growth response-l (Egr-l) gene with the survivin promoter to construct a radiation-inducible enhanced promoter, which was used to recombine a radiation-inducible oncolytic adenovirus as hSulf-1 gene vector. When I(131)-mab was incorporated into the treatment regimen, not only could the antibody produce radioimmunotherapeutic effect, but the I(131) radiation was able to further boost adenoviral proliferation. We demonstrated that the CArG-enhanced survivin promoter markedly improved the proliferative activity of the oncolytic adenovirus in HCC cells, thereby augmenting hSulf-1 expression and inducing cancer cell apoptosis. This novel strategy that involved multiple, synergistic mechanisms, including oncolytic therapy, gene therapy and radioimmunotherapy, was demonstrated to exert an excellent anti-cancer outcome, which will be a promising approach in HCC treatment.
