Abstract
Timely in situ imaging and effective treatment are efficient strategies in improving the therapeutic effect and survival rate of tumor patients. In recent years, there has been rapid progress in the development of DNA nanomaterials for tumor in situ imaging and treatment, due to their unsurpassed structural stability, excellent material editability, excellent biocompatibility and individual endocytic pathway. Tetrahedral framework nucleic acids (tFNAs), are a typical example of DNA nanostructures demonstrating superior stability, biocompatibility, cell-entry performance, and flexible drug-loading ability. tFNAs have been shown to be effective in achieving timely tumor in situ imaging and precise treatment. Therefore, the progress in the fabrication, characterization, modification and cellular internalization pathway of tFNAs-based functional systems and their potential in tumor in situ imaging and treatment applications were systematically reviewed in this article. In addition, challenges and future prospects of tFNAs in tumor in situ imaging and treatment as well as potential clinical applications were discussed.

[PMID: 34971755 DOI: 10.1016/j.ijpharm.2021.121432] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2021] [Revised: 12/09/2021] [Accepted: 12/23/2021] [Indexed: 12/23/2022]
Abstract
Aerosol therapy is a rapidly developing field of science. Due to a number of advantages, the administration of drugs to the body with the use of aerosol therapy is becoming more and more popular. Spraying drugs into the patient's lungs has a significant advantage over other methods of administering drugs to the body, including injection and oral methods. In order to conduct proper and effective aerosol therapy, it is necessary to become familiar with the basic principles and applications of aerosol therapy under various conditions. The effectiveness of inhalation depends on many factors, but most of all on: the physicochemical properties of the sprayed system, the design of the medical inhaler and its correct application, the dynamics of inhalation (i.e. the frequency of breathing and the volume of inhaled air). It is worth emphasizing that respiratory system diseases are one of the most frequently occurring and fastest growing diseases in the world. Accordingly, in recent years, a significant increase in the number of new spraying devices and pharmaceutical drugs for spraying has appeared on the market. It should also be remembered that the process of spraying a liquid is a complicated and complex process, and its efficiency is very often characterized by the use of micro- and macro parameters (including average droplet diameters or the spectrum of droplet diameter distribution). In order to determine the effectiveness of the atomization process and in the delivery of drugs to the patient's respiratory tract, the analysis of the size of the generated aerosol droplets is most often performed. Based on the proposed literature review, it has been shown that many papers dealt with the issues related to aerosol therapy, the selection of an appropriate spraying device, the possibility of modifying the spraying devices in order to increase the effectiveness of inhalation, and the possibility of occurrence of certain discrepancies resulting from the use of various measurement methods to determine the characteristics of the generated aerosol. The literature review presented in the paper was prepared in order to better understand the spraying process. Moreover, it can be helpful in choosing the right medical inhaler for a given liquid with specific rheological properties. The experimental data contained in this study are of great cognitive importance and may be of interest to entities involved in pharmaceutical product engineering (in particular in the case of the production of drugs containing liquids with complex rheological properties).

Abstract
Higher doses of radiotherapy (RT) are associated with resistance induction, therefore highly selective and controllable radiosensitizers are urgently needed. To address this issue, we developed a FeGA-based injectable hydrogel system (FH) that can be used in combination with low-dose radiation. Our FH can deliver FeGA directly to the tumor site via intratumoral injection, where it is a reservoir-based system to conserve FeGA. The photothermal properties of FeGA steadily dissolve FH under laser irradiation, and, simultaneously, FeGA reacts with a large amount of H2O2 in the cell to produce OH (Fenton reaction) which is highly toxic to mitochondria, rendering the cell inactive and reducing radiotherapy resistance. In vivo and in vitro studies suggest that combining the FH and NIR irradiation with RT (2Gy) can significantly reduce tumor proliferation without side effects such as inflammation. To conclude, this is the first study to achieve combined chemodynamic therapy (CDT) and photothermal therapy (PTT) in situ treatment, and the best therapeutic effect can be obtained with a low-dose radiation combination, thus expanding the prospects of FeGA-based tumor therapy.

Abstract
BACKGROUND This study evaluated the therapeutic efficacy of interleukin 12 (IL-12) gene therapy in Ewing sarcoma and whether murine mesenchymal stem cells (MSCs) could serve as vehicles for IL-12 gene delivery. METHODS MSCs were isolated from murine bone marrow cells. Cells were phenotyped using flow cytometry. Cultured MSCs differentiated into osteocytes and adipocytes using the appropriate media. Freshly isolated MSCs were transfected with adenoviral vectors containing either the beta-galactosidase (Ad:beta-gal) or the IL-12 (Ad:IL-12) gene. Expression of IL-12 was confirmed using reverse transcription polymerase chain reaction. Mice with TC71 Ewing sarcoma tumors were then treated intravenously with MSCs transfected with Ad:beta-gal or Ad:IL-12. Tumors were measured and analyzed by immunohistochemical analysis for expression of IL-12 protein. RESULTS Expression of both p35 and p40 IL-12 subunits was demonstrated in MSCs transfected in vitro with Ad:IL-12. IL-12 expression was seen in tumors from mice treated with MSCs transfected with Ad:IL-12. Tumor growth was also significantly inhibited compared with that in mice treated with MSCs transfected with Ad:beta-gal. CONCLUSIONS MSCs can be transfected with the IL-12 gene. These transfected cells localize to tumors after intravenous injection and induce local IL-12 protein production and the regression of established tumors.

Abstract
Genetic therapeutics show great promise toward the treatment of illnesses associated with the lungs; however, current methods of delivery such as jet and ultrasonic nebulization decrease the activity and effectiveness of these treatments. Extremely low transfection rates exhibited by non-complexed plasmid DNA in these nebulizers have been primarily attributed to poor translocation and loss of molecular integrity as a consequence of shear-induced degradation. Current research focusing on methods to increase transfection rates via the pulmonary delivery route has largely concentrated on the incorporation of carbon dioxide in the air stream to increase breath depth as well as the addition of cationic agents that condense DNA into compact, ordered complexes. The purpose of this study was to examine the impact of several classic as well as the latest atomization devices on the structure of non-complexed DNA. Various sizes of plasmid and cosmid DNA were processed through an electrostatic spray, ultrasonic nebulizer, vibrating mesh nebulizer, and jet nebulizer. Results varied dramatically based upon atomization device as well as DNA size. This may explain the inefficiency experienced by genetic therapeutics during pulmonary delivery. More importantly, this suggests that the selection of an atomization device should consider DNA size in order to achieve optimal gene delivery to the lungs.

Abstract
Cancer is a difficult target for any therapeutic strategy; therefore, there is a continuous search for new therapeutic modalities, for application either alone or in combination. In this regard, gene-based therapy is a new approach that offers hope of improved control of tumors. Intensive research to apply gene therapy for cancer treatment has led to identification of the most important technical and theoretical barriers that need to be overcome for clinical success. One of the central unresolved challenges remains the issue of specific and efficient delivery of genes to target cells or tissues, emphasizing the importance of the gene carrier. Along with different viral and non-viral vector systems, mammalian cells have also been considered as vehicles for delivery of anti-cancer therapeutics. The cell-based delivery approach was introduced as the first attempt to apply gene therapy to cancer treatment, and in general, has followed most of the ups and downs of gene therapy applications, progressing alongside new knowledge gained in this field. As a result, significant progress has been made in some aspects of the cell-based approach, while the development of other essential issues is only just gaining speed. It appears that the initial phase of development of cell-based protocols - the achievement of efficient ex vivo cell loading with therapeutics - has largely been fulfilled. However, the desired efficacy of cell-based strategies in general has not yet been reached, and specificity of tumor homing needs to be improved considerably. There is hope that advances in related scientific fields will promote the utilization of cells as powerful and versatile vehicles for cancer gene therapy.

Abstract
Pancreatic cancer is one of the commonest causes of death from cancer. Despite therapy with surgery, conventional chemotherapy, and radiation, 5-year survival for patients with this diagnosis remains poor. However, advances in the molecular understanding of this malignant disease over the past 5 years might lead to new treatment strategies. Strategies of gene therapy, antiangiogenic treatments, immunotherapy, and signal-transduction inhibition are in preclinical development. This review presents an overview of molecular therapy in pancreatic cancer.

Abstract
Activated telomerase is frequently detected in cancer cells and is able to maintain and stabilize the integrity of telomeres; it also contributes to unlimited divisions in cancer cells. Recently, a new generation of selective anticancer strategies is under development targeting the blockage of telomerase activity either at the protein level or telomerase RNA. Here, we report suppression of the malignant phenotype by the expression of the full-length antisense human telomerase RNA (hTR) delivered by a novel hybrid vector recombining adenovirus and adeno-associated virus (vAd-AAV). The hybrid vector vAd-AAV retained the unique traits from two parental viruses, such as high efficiency of gene transfer in mammalian cells and the ability to integrate into the genomic DNA of host cells. The stable expression of antisense hTR in MCF-7 cells significantly suppressed telomerase activity and progressively shortened telomere length for 30 population doublings (PD30). Expression of antisense hTR leads to a telomere-based growth arrest and the induction of spontaneous apoptosis. Antisense hTR decreased soft agar colony formation and reduced the cell proliferation, leading to exit from the cell cycle at G1 at PD15. The expression of antisense hTR also sensitized MCF-7 cells to apoptosis induced by sodium butyrate or serum starvation. Our study demonstrates that delivering antisense hTR by the hybrid Ad/AAV vector is an effective antineoplastic gene therapeutic strategy, which significantly suppresses the malignant phenotype and enhances apoptosis of human breast cancer cells.
