Abstract
BACKGROUND Cell-assisted lipotransfer (CAL) is a novel technique for fat grafting that combines the grafting of autologous fat and adipose-derived stromal cells (ASCs) to enhance fat graft retention; however, its oncologic safety is controversial. METHODS Herein, we investigated the oncologic safety of CAL for breast reconstruction using a murine model of residual breast cancer. Various concentrations of 4T1 cells (murine breast cancer cells) were injected into female mastectomized BALB/c mice to determine the appropriate concentration for injection. One week after injection, mice were divided into control (100 μL fat), low CAL (2.5 × 105 ASCs/100 μL fat), and high CAL (1.0 × 106 ASCs/100 μL fat) groups, and fat grafting was performed. The injection of 5.0 × 103 4T1 cells was appropriate to produce a murine model of residual breast cancer. RESULTS The weight of the fat tumor mass was significantly higher in the high CAL group than in the other groups (p < 0.05). However, the estimated tumor weight was not significantly different between the groups. Additionally, the fat graft survival rate was significantly higher in the high CAL group than in the control and low CAL groups (p < 0.05). No significant difference was noted in the percentage of Ki-67-positive cells, suggesting that tumor proliferation was not significantly different between the groups. CONCLUSION In summary, CAL significantly improved fat graft survival without affecting tumor size and proliferation in a murine model of residual breast cancer. These results highlight the oncologic safety of CAL for breast reconstruction.

Proliferation Pattern of Pediatric Tumor-Derived Mesenchymal Stromal Cells and Role in Cancer Dormancy: A Perspective of Study for Surgical Strategy. Front Pediatr 2021; 9:766610. [PMID: 34805051 PMCID: PMC8600142 DOI: 10.3389/fped.2021.766610] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/29/2021] [Accepted: 10/01/2021] [Indexed: 01/16/2023] Open
Abstract
The explanation for cancer recurrence still remains to be fully elucidated. Moreover, tumor dormancy, which is a process whereby cells enter reversible G0 cell cycle arrest, appears to be a critical step in this phenomenon. We evaluated the cell cycle proliferation pattern in pediatric tumor-derived mesenchymal stromal cells (MSCs), in order to provide a better understanding of the complex mechanisms underlying cancer dormancy. Specimens were obtained from 14 pediatric patients diagnosed with solid tumors and submitted to surgery. Morphology, phenotype, differentiation, immunological capacity, and proliferative growth of tumor MSCs were studied. Flow cytometric analysis was performed to evaluate the cell percentage of each cell cycle phase. Healthy donor bone marrow-derived mesenchymal stromal cells (BM-MSCs) were employed as controls. It was noted that the DNA profile of proliferating BM-MSC was different from that of tumor MSCs. All BM-MSCs expressed the typical DNA profile of proliferating cells, while in all tumor MSC samples, ≥70% of the cells were detected in the G0/G1 phase. In particular, seven tumor MSC samples displayed intermediate cell cycle behavior, and the other seven tumor MSC samples exhibited a slow cell cycle. The increased number of tumor MSCs in the G0-G1 phase compared with BM-MSCs supports a role for quiescent MSCs in tumor dormancy regulation. Understanding the mechanisms that promote dormant cell cycle arrest is essential in identifying predictive markers of recurrence and to promote a dedicated surgical planning.

Exogenous Hydrogen Sulfide Regulates the Growth of Human Thyroid Carcinoma Cells. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2019; 2019:6927298. [PMID: 31223424 PMCID: PMC6541980 DOI: 10.1155/2019/6927298] [Citation(s) in RCA: 25] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/01/2018] [Revised: 02/24/2019] [Accepted: 04/23/2019] [Indexed: 12/21/2022]
Abstract
Hydrogen sulfide (H2S) is involved in the development and progression of many types of cancer. However, the effect and mechanism of H2S on the growth of human thyroid carcinoma cells remain unknown. In the present study, we found that the proliferation, viability, migration, and invasion of human thyroid carcinoma cells were enhanced by 25–50 μM NaHS (an H2S donor) and inhibited by 200 μM NaHS. However, H2S showed no obvious effects on the proliferation, viability, and migration of human normal thyroid cells. Administration of 50 μM NaHS increased the expression levels of CBS, SQR, and TST, while 200 μM NaHS showed reverse effects in human thyroid carcinoma cells. After treatment with 25-50 μM NaHS, the ROS levels were decreased and the protein levels of p-PI3K, p-AKT, p-mTOR, H-RAS, p-RAF, p-MEK1/2, and p-ERK1/2 were increased, whereas 200 μM NaHS exerted opposite effects in human thyroid carcinoma cells. Furthermore, 1.4-2.8 mg/kg/day NaHS promoted the tumor growth and blood vessel formation in human thyroid carcinoma xenograft tumors, while 11.2 mg/kg/day NaHS inhibited the tumor growth and angiogenesis. In conclusion, our results demonstrate that exogenous H2S regulates the growth of human thyroid carcinoma cells through ROS/PI3K/Akt/mTOR and RAS/RAF/MEK/ERK signaling pathways. Novel H2S-releasing donors/drugs can be designed and applied for the treatment of thyroid cancer.

Abstract
Thyroid carcinoma is the most common endocrine malignancy, and the incidence of thyroid carcinoma is increasing in recent decades. CYYGQSKYC (P6), a nonapeptide with anti-lymphangiogenic effect by its binding to VEGFR-3 and selectively inhibiting VEGF-C binding to VEGFR-3, could suppress the migration and invasion of cancer cells. LSPPRYP (P9) acts as an effective bFGF/FGFR antagonist and inhibits the growth of the murine melanoma B16-F10 cells. In order to increase the anti-tumor effects of P6 and P9, we connected P6 with P9 via a flexible linker Gly-Gly-Gly (GGG) to reconstruct a novel peptide P11, CYYGQSKYCGGGLSPPRYP. In the present study, the mechanism of action of peptide P11 on the growth of human thyroid carcinoma cells both in vitro and in vivo was determined. Our results showed that peptide P11 inhibited the proliferation, viability, migration, and invasion of human thyroid carcinoma cells. Peptide P11 increased the apoptosis and decreased the protein levels of p-PI3K, p-AKT, and p-mTOR in human thyroid carcinoma cells. In addition, P11 could effectively inhibit the growth of human thyroid carcinoma xenograft tumors in nude mice. In conclusion, peptide P11 could inhibit the growth of human thyroid carcinoma by inhibiting the PI3K/Akt/mTOR signaling pathway. Novel peptides can be designed and applied for the treatment of various types of cancer.

Abstract
Mesenchymal stromal cells (MSCs) were introduced as tumor-targeted vehicles suitable for delivery of the gene-directed enzyme/prodrug therapy more than 10 years ago. Over these years key properties of tumor cells and MSCs, which are crucial for the treatment efficiency, were examined; and there are some critical issues to be considered for the maximum antitumor effect. Moreover, engineered MSCs expressing enzymes capable of activating non-toxic prodrugs achieved long-term curative effect even in metastatic and hard-to-treat tumor types in pre-clinical scenario(s). These gene-modified MSCs are termed prodrug-activating MSCs throughout the text and represent promising approach for further clinical application. This review summarizes major determinants to be considered for the application of the prodrug-activating MSCs in antitumor therapy in order to maximize therapeutic efficiency.

Abstract
Cell-based gene therapy holds a great promise for the treatment of human malignancy. Among different cells, mesenchymal stem cells (MSCs) are emerging as valuable anti-cancer agents that have the potential to be used to treat a number of different cancer types. They have inherent migratory properties, which allow them to serve as vehicles for delivering effective therapy to isolated tumors and metastases. MSCs have been engineered to express anti-proliferative, pro-apoptotic, and anti-angiogenic agents that specifically target different cancers. Another field of interest is to modify MSCs with the cytokines that activate pro-tumorigenic immunity or to use them as carriers for the traditional chemical compounds that possess the properties of anti-cancer drugs. Although there is still controversy about the exact function of MSCs in the tumor settings, the encouraging results from the preclinical studies of MSC-based gene therapy for a large number of tumors support the initiation of clinical trials.

Abstract
Stem cell-based drug delivery for cancer therapy has steadily gained momentum in the past decade as several studies have reported stem cells' inherent tropism towards tumors. Since this science is still in its early stages and there are many factors that could significantly impact tumor tropism of stem cells, some contradictory results have been observed. This review starts by examining a number of proof-of-concept studies that demonstrate the potential application of stem cells in cancer therapy. Studies that illustrate stem cells' tumor tropism and discuss the technical difficulties that could impact the therapeutic outcome are also highlighted. The discussion also emphasizes stem cell imaging/tracking, as it plays a crucial role in performing reliable dose-response studies and evaluating the therapeutic outcome of treatment protocols. In each section, the pros and cons associated with each method are highlighted, limitations are underlined, and potential solutions are discussed. The overall intention is to familiarize the reader with important practical issues related to stem cell cancer tropism and in vivo tracking, underline the shortcomings, and emphasize critical factors that need to be considered for effective translation of this science into the clinic.

Abstract
Mesenchymal stromal cells (MSC) exert either tumor-stimulatory or tumor-inhibitory effect. The outcome of the tumor-MSC interaction is dictated by the tumor-specific activating signals. We analyzed the alterations in MSC phenotype in response to stimulation by tumor-secreted paracrine factors. Paracrine factors from human melanoma A375 and glioblastoma 8MGBA cells were used for prolonged culture of MSC to produce derived cells designated DIFF(A)-MSC or DIFF(G)-MSC, respectively. Derived cells were analyzed for the specific surface markers, the expression pattern of MSC markers and fibroblast-specific proteins. Changes in the cell phenotype were evaluated using scratch wound assay and tube formation in vitro; and xenotransplant growth in vivo. Our data show induced expression of vascular endothelial growth factor 2, CD146, fibroblast-specific protein, vimentin and endosialin in DIFF(A)-MSC cells. This indicates their differentiation towards the cells with features of tumor-associated fibroblasts upon stimulation with melanoma-secreted cytokines. Paracrine stimulation in DIFF(G)-MSC led to up-regulation of the genes involved in the MSC differentiation. MSC-specific surface marker characteristics were preserved in derived DIFF(A)-MSC and DIFF(G)-MSC cells. However, we observed increased proportion of CD146 and GD2 (neural ganglioside) positive cells and decreased expression of marker NG2 in the MSC exposed to tumor-conditioned medium. Melanoma-CM increased MSC migration, glioblastoma-CM compromised angiogenic capacity of MSC in vitro and the protumorigenic effect in vivo. Our data directly compare the pleiotropic effects mediated by the malignant cells on the MSC. Secreted paracrine factors from melanoma or glioblastoma differently changed molecular traits in MSC, which explains the dual role of MSC in tumor growth.

Abstract
BACKGROUND The hierarchical model of solid tumor proposes the existence of rare tumor cell subpopulations with stem-cell properties. The glycoprotein prominin-1 (CD133) represents one of the cancer stem-cell markers in several tumor types. The CD133+ cell subpopulation was shown to be enriched for tumor-initiating and highly chemoresistant cells in human cancer(s). METHODS We investigated whether CD133+ cells derived from human medullary thyroid carcinoma (MTC) possess tumor-initiating properties in vivo and exhibit differential responses to chemotherapeutic agents. We demonstrated that separated CD133+ cells from the human MTC cell line TT are enriched for tumor-initiating cells as demonstrated by tumor formation in vivo. Nevertheless, TT CD133+ cells do not exhibit increased chemoresistance in comparison to parental cells. However, when MTC xenotransplants were treated with the chemotherapeutic drug 5-fluorouracil (5FU) in vivo, CD133 expression increased in MTC cells. RESULTS This cell line, designated FTTiv isolated from the drug-exposed xenotransplants, exhibits a significantly different response to 5FU associated with the substantial change in the expression profile of genes involved in 5FU metabolism and drug resistance. Moreover, the CD133+ tumor-initiating subpopulation derived from these drug-exposed FTTiv cells is significantly more resistant to 5FU and retains the chemoresistant properties upon FTTiv culture propagation. CONCLUSIONS These data suggest that the chemoresistant phenotype and the CD133+ MTC subpopulation emerged in response to chemotherapy in vivo.

Abstract
Background Mesenchymal stromal cells (MSCs) represent heterogeneous cell population suitable for cell therapies in regenerative medicine. MSCs can also substantially affect tumor biology due to their ability to be recruited to the tumor stroma and interact with malignant cells via direct contacts and paracrine signaling. The aim of our study was to characterize molecular changes dictated by adipose tissue-derived mesenchymal stromal cells (AT-MSCs) and the effects on drug responses in human breast cancer cells SKBR3. Methods The tumor cells were either directly cocultured with AT-MSCs or exposed to MSCs-conditioned medium (MSC-CM). Changes in cell biology were evaluated by kinetic live cell imaging, fluorescent microscopy, scratch wound assay, expression analysis, cytokine secretion profiling, ATP-based viability and apoptosis assays. The efficiency of cytotoxic treatment in the presence of AT-MSCs or MSCs-CM was analyzed. Results The AT-MSCs altered tumor cell morphology, induced epithelial-to-mesenchymal transition, increased mammosphere formation, cell confluence and migration of SKBR3. These features were attributed to molecular changes induced by MSCs-secreted cytokines and chemokines in breast cancer cells. AT-MSCs significantly inhibited the proliferation of SKBR3 cells in direct cocultures which was shown to be dependent on the SDF-1α/CXCR4 signaling axis. MSC-CM-exposed SKBR3 or SKBR3 in direct coculture with AT-MSCs exhibited increased chemosensitivity and induction of apoptosis in response to doxorubicin and 5-fluorouracil. Conclusions Our work further highlights the multi-level nature of tumor-stromal cell interplay and demonstrates the capability of AT-MSCs and MSC-secreted factors to alter the anti-tumor drug responses.

Abstract
The extent of local bystander effect induced by fusion yeast cytosine deaminase::uracil phosphoribosyltransferase (yCD) in combination with 5-fluorocytosine (5FC) was evaluated in xenogeneic model of human medullary thyroid carcinoma (MTC). This approach to gene-directed enzyme/prodrug therapy (GDEPT) induces strong bystander cytotoxicity. Effector yCD-TT mixed with target EGFP-TT cells in a ratio 2:9 could achieve significant tumor regression and 14-fold decrease in serum marker calcitonin upon 5FC administration. Histopathological analysis unraveled that antitumor effect resulted in tumor dormancy and proliferation arrest of remaining tumor cell clusters in vivo. yCD/5FC combination represents another GDEPT approach to achieve tumor growth control in MTC.

Adenovirus-mediated tissue-targeted expression of the CDglyTk gene for the treatment of breast cancer. Mol Med Rep 2012; 6:321-9. [PMID: 22641384 DOI: 10.3892/mmr.2012.925] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2012] [Accepted: 05/10/2012] [Indexed: 11/05/2022] Open
Abstract
The aim of this study was to evaluate the selective killing efficacy of adenovirus (Ad)-mediated double suicide genes driven by the kinase domain-containing receptor (KDR) promoter in human breast cancer cells and vascular endothelial cells. Two Ad-mediated double suicide gene systems [with the two suicide genes, thymidine kinase (TK) and cytosine deaminase (CD)] with the KDR promoter (Ad-KDRP-CDglyTK) and the cytomegalovirus (CMV) promoter (Ad-CMV-CDglyTK) were established and transfected into the KDR-expressing MCF7 human breast cancer, EC304 human vascular endothelial and LS174T human colon carcinoma, which does not express KDR, cell lines. The selective killing efficiency and specificity of the double suicide gene system were measured in vitro by the analysis of cellular proliferation and assayed in vivo by subcutaneous injection of MCF7 cells into nude mice. The microvessel density (MVD) in the transplanted tumor was determined by immunohistochemical staining of CD34 cells. Our results showed that the transgenic CDglyTK genes were expressed in three cell lines (MCF7, ECV304 and LS174T) infected with Ad-CMV-CDglyTK. However, of the cells infected with Ad-KDRP-CDglyTK, the transgenic CDglyTK gene was only expressed in the KDR-expressing MCF7 and ECV304 cells, but not in the KDR-deficient LS174T cells. Cell proliferation was significantly reduced in a dose-dependent manner by pre-treatment with ganciclovir (GCV) and 5-fluorocytosine (5-FC) in MCF7 and ECV304 cells with transfected KDRP-CDglyTK genes and the three cell lines transfected with the CMV-CDglyTK genes. Similar results were not observed in the LS174T cells with transfected KDRP-CDglyTK genes. The results of this study show that the tumor-targeted expression of CDglyTK driven by the KDR promoter has a high specificity and performance. The killing effect of the CD/TK fusion gene in the target cells was significantly increased compared with the single suicide gene. The cell cycle of MCF7 and ECV304 cells transfected with KDRP-CDglyTK genes was arrested at the S phase following treatment with the prodrugs. The tumors formed by the MCF7 cells with the double suicide gene system were much smaller and the MVD of the tumor tissue was significantly decreased compared with the control. This study demonstrates that tumor‑targeted expression of the CDglyTK gene driven by the KDR promotor may be a novel strategy for the gene therapy of human breast cancer.
