Abstract
The current state of cancer treatment is still far from being satisfactory considering the strong impairment of patients' quality of life and the high lethality of malignant diseases. Therefore, it is critical for innovative approaches to be tested in the near future. In view of the crucial role that is played by tumor immunity, the present review provides essential information on the immune-mediated effects potentially generated by the interplay between ionizing radiation and cytotoxic antitumor agents when interacting with target malignant cells. Therefore, the radiation-dependent abscopal effect (i.e., a biological effect of ionizing radiation that occurs outside the irradiated field), the influence of cancer chemotherapy on the antigenic pattern of target neoplastic cells, and the immunogenic cell death (ICD) caused by anticancer agents are the main topics of this presentation. It is widely accepted that tumor immunity plays a fundamental role in generating an abscopal effect and that anticancer drugs can profoundly influence not only the host immune responses, but also the immunogenic pattern of malignant cells. Remarkably, several anticancer drugs impact both the abscopal effect and ICD. In addition, certain classes of anticancer agents are able to amplify already expressed tumor-associated antigens (TAA). More importantly, other drugs, especially triazenes, induce the appearance of new tumor neoantigens (TNA), a phenomenon that we termed drug-induced xenogenization (DIX). The adoption of the abscopal effect is proposed as a potential therapeutic modality when properly applied concomitantly with drug-induced increase in tumor cell immunogenicity and ICD. Although little to no preclinical or clinical studies are presently available on this subject, we discuss this issue in terms of potential mechanisms and therapeutic benefits. Upcoming investigations are aimed at evaluating how chemical anticancer drugs, radiation, and immunotherapies are interacting and cooperate in evoking the abscopal effect, tumor xenogenization and ICD, paving the way for new and possibly successful approaches in cancer therapy.

Enhancement of chemosensitivity in 5-fluorouracil-resistant colon cancer cells with carcinoembryonic antigen-specific RNA aptamer. Mol Biol Rep 2019; 46:3835-3842.

Abstract
Colorectal cancer (CRC) is one of the most common cancers, and rates of incidence and diagnosis of CRC have gradually increased. Carcinoembryonic antigen (CEA) is overexpressed in patients with CRC and is associated with cell adhesion, anoikis resistance, and promotion of metastasis to the liver. 5-Fluorouracil (5-FU) is a chemotherapeutic drug used to treat cancer, including CRC. However, a major issue of 5-FU therapy is the occurrence of chemoresistance, and the fact that 5-FU induces CEA overexpression, which may induce the 5-FU resistance. We previously isolated a CEA-specific RNA aptamer that was able to inhibit hepatic metastasis of colon cancer cells in a mouse model. In the present study, we tested whether protecting CEA using the CEA aptamer could enhance 5-FU sensitivity in chemoresistant LS174T colon cancer cells. We observed that the CEA aptamer sensitized the 5-FU-resistant colon cancer cell line to 5-FU more than five-fold (IC50 ~ 5.995 μM), compared with cells treated with 5-FU alone (IC50 ~ 31.46 μM). Moreover, treatment with CEA aptamer combined with 5-FU synergistically regressed growth of chemoresistant tumors in mouse xenografted models. Combinatorial treatment of 5-FU and CEA aptamer augmented caspase-8 activity in the 5-FU-resistant colon cancer cell line via aptamer-mediated disruption of CEA interaction with death receptor 5 and in mouse xenograft tumors. In conclusion, CEA-specific aptamer improved 5-FU sensitivity in chemoresistant colon cancer cells in vitro and in vivo, and thus represents a novel 5-FU adjuvant to overcome the chemoresistance in CRC patients.

Fabrication of an ultrasensitive and selective electrochemical aptasensor to detect carcinoembryonic antigen by using a new nanocomposite. Biosens Bioelectron 2019; 129:1-6. [PMID: 30677696 DOI: 10.1016/j.bios.2018.12.047] [Citation(s) in RCA: 44] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2018] [Revised: 12/16/2018] [Accepted: 12/21/2018] [Indexed: 01/15/2023]
Abstract
A lable-free electrochemical aptasensor was successfully developed for the sensitive detection of carcinoembryonic antigen as a tumor biomarker. To do this, a ternary nanocomposite of hemin, graphene oxide and multi-walled carbon nanotubes was used. The aptamer can be attached to the surface of a hemin, graphene oxide and multi-walled carbon nanotubes glassy carbon electrode through -NHCO- covalent bonds to form a sensing surface. Through fourier transform infrared spectroscopy and scanning electron microscopy, it was indicated that hemin can be successfully incorporated into hemin, graphene oxide and multi-walled carbon nanotubes. Hemin, which protects graphene nanosheets, also serves as an in-situ probe owing to its well-defined redox properties. Multi-walled carbon nanotubes in the modifier enhance conductivity and facilitate the electron transfer between hemin and the glassy carbon electrode. In this study, carcinoembryonic antigen got specifically bound to the aptamer, and the current changes were used for selective and specific detection of that antigen. The devised aptasensor proved to have excellent performance with a wide linear range of 1.0 × 10-15 - 1.0 × 10-8 gmL-1 and a detection limit of 0.82 fg mL-1. The inter-day and intra-day values of RSD% were obtained in the range of 0.10-2.91 and 2.21-4.56 respectively. According to the experiments conducted on real samples, it may be claimed that the proposed label-free electrochemical aptasensor is capable enough of determining carcinoembryonic antigen in clinical diagnostics.

Abstract
Background KIF20A is well known as one of the key proteins in mitosis. Recently, a number of studies illustrated that KIF20A might function as an oncogene in some carcinomas. However, its expression levels and clinical value remained unclear in gastric cancer (GC). Patients and methods In this study, we investigated the expression of KIF20A in samples from GC patients and cell lines by quantitative real-time PCR and Western blot. The function of KIF20A in cell proliferation of GC cell lines was examined via cell viability and colony formation assays. Immunohistochemistry assay based on a tissue microarray consisting of 146 cases was performed to evaluate the prognostic value of KIF20A. The overall survival rate of 122 GC patients based on KIF20A expression was analyzed as well. Finally, using KIF20A inhibitor, genistein, and combining it with cisplatin or fluorouracil, the antitumor effects were studied. Results Most GC samples (56.76%) showed higher KIF20A expression level compared to their corresponding normal specimens, which demonstrated the potential oncogenic role of KIF20A in GC. The functional studies elucidated the essential role of KIF20A in GC cell proliferation. Besides, tissue microarray result showed that the expression level of KIF20A was significantly related to the histological grades (P=0.036). Furthermore, we found the expression of KIF20A was related to poor overall survival rate, which is coincident with the results from Kaplan–Meier plotter database. In addition, we found that a KIF20A inhibitor, genistein, could enhance the antitumor activity of cisplatin and fluorouracil, which might be considered as a chemosensitive agent in GC. Conclusion KIF20A can promote cell proliferation in GC, which might be used as an independent prognostic factor and a potential therapeutic target.

Abstract
Purpose We evaluated the higher levels of carcinoembryonic antigen (CEA) secreted by the LoVo human colon carcinoma cells in a medium containing anticancer drugs. Drug-resistant LoVo cells were analyzed by subcutaneously xenotransplanting them into mice. The aim of this study was to evaluate whether the drug-resistant cells isolated in this study were cancer-initiating cells, known also as cancer stem cells (CSCs). Methods The production of CEA was investigated in LoVo cells that were cultured with 0–10 mM of anticancer drugs, and we evaluated the increase in CEA production by the LoVo cells that were stimulated by anticancer drug treatment. The expression of several CSC markers in LoVo cells treated with anticancer drugs was also evaluated. Following anticancer drug treatment, LoVo cells were injected subcutaneously into the flanks of severe combined immunodeficiency mice in order to evaluate the CSC fraction. Results Production of CEA by LoVo cells was stimulated by the addition of anticancer drugs. Drug-resistant LoVo cells expressed lower levels of CSC markers, and LoVo cells treated with any of the anticancer drugs tested did not generate tumors within 8 weeks from when the cells were injected subcutaneously into severe combined immunodeficiency mice. These results suggest that the drug-resistant LoVo cells have a smaller population of CSCs than the untreated LoVo cells. Conclusion Production of CEA by LoVo cells can be stimulated by the addition of anticancer drugs. The drug-resistant subpopulation of LoVo colon cancer cells could stimulate the production of CEA, but these cells did not act as CSCs in in vivo tumor generation experiments.

Abstract
MicroRNAs (miRNAs) are small noncoding RNA molecules produced by miR genes which are able to control the expression of a large number of cellular proteins by targeting mRNAs of protein coding genes. It has been suggested that modification of miR gene expression could be an important factor in the development and maintenance of the neoplastic state. It is also reasonable to hypothesize that antineoplastic drugs could be able to alter miR gene expression pattern since most of them are able to interfere with nucleic acid metabolism and gene expression. Here we show that 5-fluorouracil (5-FU), a classical antimetabolite largely used in the clinic, is able to change significantly the expression of several miR genes. In colon cancer cells, at a clinically relevant concentration, the drug up-regulates or down-regulates in vitro the expression of 19 and 3 miR genes, respectively, by a factor of not less than two-fold. In some instances, 5-FU up-regulates miR genes that are already over-expressed in neoplastic tissues, including, for example, miR-21 that is associated with anti-apoptotic functions characterizing malignant cells. In this case, it is possible that drug-induced miR gene dysregulation could be the expression of cellular response to the toxic effects of the agent. On the contrary, in other instances the drug influences the expression of miR genes in a direction that is opposite to that induced by neoplastic transformation. A typical example is provided by miR-200b, that is up-regulated in various tumors and down-regulated by treatment with the antimetabolite. Noteworthy, it is known that miR-200b suppresses a gene that codes for a protein tyrosine phosphatase (PTPN12) that inactivates products of oncogenes, such as c-Abl, Src or Ras. In conclusion, the present results support the hypothesis that 5-FU can alter profoundly miR gene expression pattern. This effect could be responsible, at least in part, of the multi-target pleiotropic influence manifested by the drug on malignant cells.
