Abstract
OBJECTIVES In pancreatic islet transplantation studies, bioluminescence imaging enables quantitative and noninvasive tracking of graft survival. Amid the recent heightened interest in extrahepatic sites for islet and stem cell-derived beta-like cell transplantations, proper understanding the nature of bioluminescence imaging in these sites is important. METHODS Islets isolated from Firefly rats ubiquitously expressing luciferase reporter gene in Lewis rats were transplanted into subcutaneous or kidney capsule sites of wild-type Lewis rats or immunodeficient mice. Posttransplant changes of bioluminescence signal curves and absorption of bioluminescence signal in transplantation sites were examined. RESULTS The bioluminescence signal curve dynamically changed in the early posttransplantation phase; the signal was low within the first 5 days after transplantation. A substantial amount of bioluminescence signal was absorbed by tissues surrounding islet grafts, correlating to the depth of the transplanted site from the skin surface. Grafts in kidney capsules were harder to image than those in the subcutaneous site. Within the kidney capsule, locations that minimized depth from the skin surface improved the graft detectability. CONCLUSIONS Posttransplant phase and graft location/depth critically impact the bioluminescence images captured in islet transplantation studies. Understanding these parameters is critical for reducing experimental biases and proper interpretation of data.

Robustness of Propofol and Sevoflurane on the Perioperative Immune Function of Patients Undergoing Laparoscopic Radical Nephrectomy. JOURNAL OF ONCOLOGY 2022; 2022:1662007. [PMID: 35136408 PMCID: PMC8818401 DOI: 10.1155/2022/1662007] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/22/2021] [Revised: 12/21/2021] [Accepted: 12/30/2021] [Indexed: 01/02/2023]
Abstract
Objective. This study aimed to evaluate the robustness of propofol combined with sevoflurane in patients undergoing laparoscopic radical nephrectomy and its influence on immune function during perioperative period. A total of 140 patients who underwent laparoscopic nephrectomy in the Department of Oncology of our hospital from January 2018 to January 2020 were divided into the control group and the study group by the random number table method, with 70 cases in each group, who were given sevoflurane anesthesia and sevoflurane combined with propofol anesthesia, respectively. The anesthesia effect and perioperative immune function of the two groups of patients were compared. No remarkable difference was observed in the extubation time, breathing recovery time, and awakening time between the two groups; the extubation coughing score and postextubation restlessness score of the study group were significantly lower than those of the control group; the postoperative renal function indexes of the two groups of patients were not considerably different; after treatment, the CD3+ (%), CD4+ (%), and CD4+/CD8+ of the two groups of patients decreased significantly, with a higher level in the study group. For patients undergoing laparoscopic radical nephrectomy, the combination of propofol and sevoflurane yields a promising outcome in enhancing the anesthesia results and improving the perioperative immune function.

Abstract
The increase in the life expectancy of patients with renal cell carcinoma (RCC) in the last decade is due to changes that have occurred in the area of preclinical studies. Understanding cancer pathophysiology and the emergence of new therapeutic options, including immunotherapy, would not be possible without proper research. Before new approaches to disease treatment are developed and introduced into clinical practice they must be preceded by preclinical tests, in which animal studies play a significant role. This review describes the progress in animal model development in kidney cancer research starting from the oldest syngeneic or chemically-induced models, through genetically modified mice, finally to xenograft, especially patient-derived, avatar and humanized mouse models. As there are a number of subtypes of RCC, our aim is to help to choose the right animal model for a particular kidney cancer subtype. The data on genetic backgrounds, biochemical parameters, histology, different stages of carcinogenesis and metastasis in various animal models of RCC as well as their translational relevance are summarized. Moreover, we shed some light on imaging methods, which can help define tumor microstructure, assist in the analysis of its metabolic changes and track metastasis development.

Abstract
Despite being widely used in reporter technologies, bioluminescent systems are largely understudied. Of at least forty different bioluminescent systems thought to exist in nature, molecular components of only seven light-emitting reactions are known, and the full biochemical pathway leading to light emission is only understood for two of them. Here, we provide a succinct overview of currently known bioluminescent systems highlighting available tools for research and discussing future applications.

Abstract
Bioluminescence (BL) is a spectacular phenomenon involving light emission by live organisms. It is caused by the oxidation of a small organic molecule, luciferin, with molecular oxygen, which is catalysed by the enzyme luciferase. In nature, there are approximately 30 different BL systems, of which only 9 have been studied to various degrees in terms of their reaction mechanisms. A vast range of in vitro and in vivo analytical techniques have been developed based on BL, including tests for different analytes, immunoassays, gene expression assays, drug screening, bioimaging of live organisms, cancer studies, the investigation of infectious diseases and environmental monitoring. This review aims to cover the major existing applications for bioluminescence in the context of the diversity of luciferases and their substrates, luciferins. Particularly, the properties and applications of d-luciferin, coelenterazine, bacterial, Cypridina and dinoflagellate luciferins and their analogues along with their corresponding luciferases are described. Finally, four other rarely studied bioluminescent systems (those of limpet Latia, earthworms Diplocardia and Fridericia and higher fungi), which are promising for future use, are also discussed.

BMP-2 inhibits tumor-initiating ability in human renal cancer stem cells and induces bone formation. J Cancer Res Clin Oncol 2014; 141:1013-24.

Abstract
PURPOSE We have previously shown that BMP-2 induces bone formation and inhibits tumorigenicity of cancer stem cells (CSCs) in a human osteosarcoma OS99-1 cell line. In this study, we sought to determine whether BMP-2 can similarly induce bone formation and inhibit the tumorigenicity of renal CSCs identified based on aldehyde dehydrogenase (ALDH) activity in renal cell carcinoma (RCC) cell lines and primary tumors. METHODS Using a xenograft model in which cells from human RCC cell lines ACHN, Caki-2, and primary tumors were grown in NOD/SCID mice, renal CSCs were identified as a subset of ALDH(br) cells. The ALDH(br) cells possessed a greater colony-forming efficiency, higher proliferative output, increased expression of stem cell marker genes Oct3/4A, Nanog, renal embryonic marker Pax-2, and greater tumorigenicity compared to cells with low ALDH activity (ALDH(lo) cells), generating new tumors with as few as 25 cells in mice. RESULTS In vitro, BMP-2 was found to inhibit the ALDH(br) cell growth, down-regulate the expression of embryonic stem cell markers, and up-regulate the transcription of osteogenic markers. In vivo, all animals receiving a low number of ALDH(br) cells (5 × 10(3)) from ACHN, Caki-2, and primary tumor xenografts treated with 30 µg BMP-2 per animal showed limited tumor growth with significant bone formation, while untreated cells developed large tumor masses without bone formation. CONCLUSIONS These results suggest that BMP-2 inhibits the tumor-initiating ability of renal CSCs and induces osseous bone formation. BMP-2 may therefore provide a beneficial strategy for human RCC treatment by targeting the CSC-enriched population.

Abstract
Nanoparticles have received enormous attention as a promising tool to enhance target-specific drug delivery and diagnosis. Various in vitro and in vivo techniques are used to characterize a new system and predict its clinical efficacy. These techniques enable efficient comparison across nanoparticles and facilitate a product optimization process. On the other hand, we recognize their limitations as a prediction tool, due to inadequate applications and overly simplified test conditions. We provide a critical review of in vitro and in vivo techniques currently used for evaluation of nanoparticles and introduce emerging techniques and models that may be used complementarily.

Effect of host immunity on metastatic potential in renal cell carcinoma: the assessment of optimal in vivo models to study metastatic behavior of renal cancer cells. Tumour Biol 2012; 33:551-9. [PMID: 22219032 DOI: 10.1007/s13277-011-0300-4] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2011] [Accepted: 12/15/2011] [Indexed: 10/14/2022] Open
Abstract
There has been little information about metastatic behavior of renal cell carcinoma (RCC) cells because human cancers metastasize only rarely in immunodeficient mice. Moreover, it is difficult to know the effect of host immunity on RCC metastasis due to lack of such RCC cells as transplantable in not only xenograft models but also counterparts with intact immunity. Therefore, we scrutinized in vivo metastasis of RCC cells to seek for the optimal preclinical model to study metastatic behavior. The luciferase-expressing three representative human RCC cell lines (Caki-1, A498, and 786-O) and rat ACI-RCC cell which were established in our laboratory were transplanted into nonobese diabetic/severe combined immunodeficient (NOD/SCID) mice or immunocompetent ACI rats by intracardiac injection as well as orthotopic inoculation. Metastasis was monitored using a bioluminescent imaging technique. Metastasis was rare in the three human RCC cells even when they were directly disseminated into systemic circulation under the condition least susceptible to host immune attack in NOD/SCID mice. In contrast, ACI-RCC cells spontaneously metastasized to pulmonary tissue from orthotopic tumor sites and systemically spread via intracardiac route. Metastases were more extensive when the cells were inoculated into an immunodeficient host, implying suppressive effect of host immunity on colonization of RCC cells. These results suggest that the representative human RCC cells are not adequate resource to study metastasis but that the luciferase-labeled ACI-RCC cell characterized by its luminescent stability, enhanced tumorigenicity, and widespread metastatic potential provides a useful in vivo model for preclinical assessment of cancer progression and potential therapies against RCC.
