Abstract
Transcatheter arterial chemoembolization (TACE) is the first choice for patients with intermediate hepatocellular carcinoma (HCC), but clinical applications still face some problems, such as the difficulties in clearing all cancer cells and lack of targeting, which would damage normal liver cells. Recently, photothermal therapy (PTT) and nanodelivery systems have been used to improve the efficacy of TACE. However, most of these strategies achieve only a single function, and the synthesis process is complicated. Here, a simple one-step solvothermal method was used to develop multifunctional nanoparticles (UiO-66/Bi2S3@DOX), which can simultaneously achieve photothermal effects and low pH-triggered DOX release. UiO-66/Bi2S3 exhibited a pH-responsive release behavior and an excellent photothermal effect in a series of in vitro and in vivo studies. Biocompatibility was confirmed by cytotoxicity and hemocompatibility evaluations. The rat N1S1 liver tumor model was established to investigate the therapeutic effect and biosafety of the nanoplatforms using TACE. The results revealed that the combination of TACE and PTT resulted in remarkable tumor growth inhibition, and the histopathological assay further revealed extensive necrosis, downregulated angiogenesis, increased apoptosis, and proliferation in the tumor response. These results demonstrated that this nanosystem platform was a promising therapeutic agent for enhancing TACE therapy for HCC treatment.

Exp Ther Med 2018; 17:1312-1320. [PMID: 30680008 PMCID: PMC6327625 DOI: 10.3892/etm.2018.7047] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2017] [Accepted: 06/01/2018] [Indexed: 01/04/2023] Open
Abstract
Effective therapies to reduce ischemia/reperfusion and hypoxia/reoxygenation injury are currently lacking. Furthermore, the effects of loperamide and microRNA (miR)-21 on hypoxia/reoxygenation injury of cardiomyocytes have remained to be elucidated. Therefore, the present study aimed to investigate the effect of loperamide and miR-21 on cardiomyocytes during hypoxia/reoxygenation injury, and to explore the underlying molecular mechanisms. H9c2 rat cardiomyocytes were pre-treated with loperamide prior to hypoxia/reoxygenation. The viability of H9c2 cells was measured with a cell counting kit 8 and apoptosis was detected with an Annexin V-phycoerythrin/7-aminoactinomycin D apoptosis kit. Furthermore, reactive oxygen species were detected with a specific kit. Genes regulated by miR-21 were screened with an mRNA chip and confirmed using reverse-transcription quantitative polymerase chain reaction analysis. The direct targeting relationship of miR-21 with certain mRNAs was then confirmed using a Dual-Luciferase Reporter Assay system. The results indicated that the apoptotic rate and reactive oxygen species levels in rat cardiomyocytes were markedly increased after hypoxia/reoxygenation treatment. Pre-treatment with loperamide significantly protected H9c2 cells against apoptosis and reactive oxygen species production after hypoxia/reoxygenation. The protection was markedly decreased by miR-21 inhibitor and enhanced by miR-21 mimics. Screening for genes associated with cardiomyocyte apoptosis revealed that the relative expression of A-kinase anchoring protein 8 (Akap8) and BRCA1 associated RING domain 1 (Bard1) was consistent with the experimental results on apoptosis and reactive oxygen species. Compared with the group treated by hypoxia/reoxygenation alone, pre-treatment with loperamide markedly decreased the expression of BRCA1-interacting protein C-terminal helicase 1, Akap8 and Bard1 after hypoxia/reoxygenation. The decrease in the expression of Akap8 and Bard1 was markedly attenuated by miR-21 inhibitor and enhanced by miR-21 mimics. miR-21 mimics directly targeted the 3′-untranslated region (UTR) of Akap8 and Bard1 mRNA to thereby decrease their expression. In conclusion, the protection of rat cardiomyocytes against hypoxia/reoxygenation-induced apoptosis and reactive oxygen species production by loperamide was markedly enhanced by miR-21. miR-21 directly targets the 3′-UTR of Akap8 and Bard1 mRNA and enhances the inhibitory effects of loperamide on Akap8 and Bard1 expression in rat cardiomyocytes after hypoxia/reoxygenation.

Abstract
Suxiao Jiuxin Pill (SX), a traditional Chinese medicine compound consisting primarily of tetramethylpyrazine and borneol, has been reported to protect against ischemic heart disease. However, the effects of SX on mitochondrial injury and gene expression in various signaling pathways are unclear. The aim of the present study was to investigate the effects of SX on mitochondrial injury and to screen the expression of genes potentially altered by SX using a cell culture model of ischemic injury. Simulated ischemia was established by culturing HL-1 cardiomyocytes in Dulbecco's modified Eagle medium without glucose or serum in a hypoxic chamber containing 95% N2 and 5% CO2 for 24 h. HL-1 cardiomyocytes were divided into 3 groups: Control, ischemic injury and ischemic injury + SX (100 µg/ml; n=3 wells/group). Mitochondrial membrane potential was detected by staining with JC-1 dye. The mRNA expression levels of adenylyl cyclase (Adcy) 1–9, adrenoceptor β1, Akt1, ATPase Na+/K+ transporting subunit β2, calcium voltage-gated channel auxiliary subunit α2δ (Cacna2d)2, Cacna2d3, calcium channel voltage-dependent γ subunit 8, cytochrome C oxidase subunit 6A2 (Cox6a2), fibroblast growth factor receptor (Fgfr) 4, Fgf8, Fgf12, Gnas complex locus, glycogen synthase kinase 3β (Gsk3b), mitogen-activated protein kinase (Mapk)11-14, Mapk kinase kinase kinase 1 (Map4k1), Mas1, nitric oxide synthase 3 (Nos3), phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit α (Pik3ca), phospholipase A2 group 4A, rap guanine nucleotide exchange factor 4 and ryanodine receptor 2 were detected using reverse transcription-quantitative polymerase chain reaction. The protein expression levels of phosphoinositide 3-kinase (PI3K), MAS-1 and phosphorylated-endothelial NOS were also examined by immunofluorescence staining. The decrease in mitochondrial membrane potential in the cell culture model of ischemic injury (P<0.001) was significantly attenuated by SX treatment (P<0.001). Furthermore, increases in the mRNA expression levels of Adcy2 (P<0.05), 3 (P<0.01) and 8 (P<0.05) in the ischemic injury model were significantly attenuated by SX treatment (P<0.01), and SX treatment significantly decreased the mRNA expression levels of Adcy1 (P<0.01) and 6 (P<0.05) in ischemic cells. Decreases in the mRNA expression levels of Cox6a2 (P<0.001), Gsk3b (P<0.01) and Pik3ca (P<0.001) in the ischemic injury model were also significantly attenuated by SX treatment (P<0.05, P<0.01 and P<0.001, respectively). In addition, the decrease in the protein expression of PI3K (P<0.001) was significantly attenuated by SX treatment (P<0.001). The present findings indicate that SX may protect cardiomyocytes against mitochondrial injury and attenuate alterations in the gene expression of Adcy2, 3 and 8, Cox6a2, Gsk3b and Pik3ca during ischemic injury.

Abstract
Cervical carcinoma is the second most common malignancy among women in both incidence and mortality. Although much is known about the etiology and treatment of cervical cancer, the role of genetic alterations in the multistep pathway of cervical tumorigenesis is largely unknown. The aim of this study was to characterize the genomic changes in the cervical pre-cancerous lesions and tumors, induced by different types of human papillomaviruses. In this research was used the BlueGnome CytoChip oligo 2 × 105 K microarray for whole-genome oligo-array CGH. Microarray CGH analysis of 40 specimens was carried out-12 specimens from patients with early-stage squamous cell carcinomas; 19 specimens from patients with mild to moderate dysplasia and 9 with severe dysplasia. First we performed microarray CGH analysis of five DNA pools which contained the DNA from homogeneous groups of patients. The results revealed presence of micro chromosomal aberrations in chromosome region 14q11.2. According to the genome database these aberrations represent polymorphisms. Microarray analysis of DNA from 9 separate carcinoma lesions revealed a total of 26 aberrations in 14 chromosomes of nine patients. Our results showed the advantages of high-resolution chips in the clinical diagnosis of patients with cancerous and precancerous lesions caused by viral infection with HPV, but also highlight the need for extensive population studies revealing the molecular nature and clinical significance of different CNVs and the creation of detailed maps of variations in the Bulgarian population. This would facilitate extremely precise interpretation of specific genomic imbalances in the clinical aspect.

Abstract
Myeloid zinc finger 1 (MZF1) gene belongs to the Kruppel family of zinc finger transcription factors. MZF1 has been suggested to play an important role in the tumorigenesis, invasion, and apoptosis of various tumor cells. However, the role of MZF1 in human cervical cancer remains unclear. To investigate the molecular mechanisms of MZF1 and its functional role in human cervical cancer cell migration and invasion, we experimented on stable SiHa cells overexpressing MZF1. We found that MZF1 overexpression inhibits the migratory and invasive abilities of SiHa cervical cancer cells. In addition, the overexpression of MZF1 significantly reduces MMP-2 protein and mRNA levels. Luciferase and ChIP assays suggested that MZF1 directly binds to MMP-2 gene regulatory sequences in vivo and suppresses MMP-2 promoter activity in vitro. This study shows that MZF-1 represses MMP-2 transcription and suggests that this repression may be linked to inhibition of human cervical cancer cell migration and metastasis.

Abstract
Membrane type 1-matrix metalloproteinase (MT1-MMP) participates in the activity of MMP-2, which correlates with cancer of uterine cervix. Single-nucleotide polymorphisms (SNPs) in promoter and exon of MT1-MMP may influence their binding with transcription factors and gene transcription. To date, no study reports the association of the MT1-MMP polymorphisms with cervical neoplasia. Therefore, we investigated the influence of the MT1-MMP gene polymorphisms on the susceptibility and clinicopathological variables of cervical neoplasia for women in Taiwan. We recruited 72 patients with cervical squamous cell carcinoma and 63 with high-grade dysplasia as 1 subgroup. Meanwhile, 280 control women were included as another subgroup. The SNPs rs1003349 (site -165), rs2236307 (+7096), and rs3751489 (+8153) as well as rs2236302 (site +6727) of MT1-MMP gene were determined by polymerase chain reaction (PCR)-restriction fragment length polymorphism and real-time PCR genotyping, respectively. Then, we correlated these SNPs and haplotypes with the development of cervical neoplasia and cancer clinicopathological variables. We found that women with CC genotype in rs2236307 SNP exhibited a more risk to develop cervical neoplasia as compared with those with wild genotype TT. Haplotypes -165 T, +6727 C, +7096 C, +8153 G or -165 G, +6727 G, +7096 T, and +8153 G and diplotypes including at least 1 type of these haplotypes of MT1-MMP gene showed a higher risk of cervical neoplasia. However, both haplotypes were not significantly correlated with the clinicopathological characteristics of cervical cancer. In conclusion, Taiwan women with variant homozygote CC (+7096) and haplotypes, TCCG and GGTG, of MT1-MMP exhibit more risk in developing cervical neoplasia.

Abstract
This study was designed to investigate the role of intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) during chronic cardiac allograft rejection. Wistar rats were used as donors, and SD rats as recipients heterotopic cardiac transplants. Recipients pretreated with inoculation of donor splenocytes (SPC) followed by cyclophosphamide (CP) were divided into 4 groups: (A) untreated group (n = 18) without immunosuppression; (B) SPC plus CP-treated group (n = 18) that were euthanized at 15-120 days posttransplantation; (C) CsA-treated group (n = 18) euthanized at 2-3 months posttransplantation; and (D) tolerance group (n = 18) treated with SPC plus CP and monitored for at least 1 year posttransplantation. Cardiac allografts were harvested at various times for immunohistochemical studies performed to evaluate the expression of ICAM-1 and VCAM-1. Pretreatment of animals with SPC and CP induced long-term cardiac allograft survival. Immunohistochemical staining demonstrated a low level of ICAM-1 and VCAM-1 expression in cardiac allograft muscle and coronary arteries among Groups B and D. In contrast, the expressions of ICAM-1 and VCAM-1 in cardiac allografts of Groups A and C were significantly higher than those in Groups B and D. Our results suggested that the expression of ICAM-1 and VCAM-1 plays an important role during the development of chronic cardiac allograft rejection.

Clinical significance of matrix metalloproteinase-2 in cancer of uterine cervix: a semiquantitative study of immunoreactivities using tissue array. Gynecol Oncol 2008; 108:533-42.

Abstract
OBJECTIVES To study the expression of matrix metalloproteinase-2 (MMP-2) in cancer of uterine cervix and correlate its expression with clinicopathological parameters, recurrence and survival of patients. METHODS Twenty cervical cancer and 20 normal tissues from the same patients were collected to detect MMP-2 mRNA expression. From them, 16 cancer and 16 normal tissues were collected and added with another 64 cancer tissues to construct a 96-tissue core microarray for immunohistochemical study. We evaluated the relationships among MMP-2 immunoreactivity using semiquantitative H scores, obtained by multiplying proportion score of stained cells and their mean digital density, and clinicopathological variables, recurrence and survival in cervical cancer patients. We used univariate and multivariate analyses of all parameters for recurrence and survival, further including time interval for evaluation. RESULTS MMP-2 mRNA expression was higher in most of cervical cancerous tissues than normal counterparts. H score of MMP-2 was significantly higher in cancerous tissue cores than normal counterparts (median H scores: 1.5 vs. 0.3, P<0.001). MMP-2 expression was significantly associated with parametrium invasion (P=0.004) and lymph node metastasis (P=0.015), but not with cancer recurrence, recurrence-free and overall survival rates of these patients. However, poor tumor cell differentiation and positive parametrium invasion significantly increased the recurrence and poor cell differentiation increased the risk of death. CONCLUSIONS MMP-2 is highly expressed in cervical cancer tissues at mRNA and protein levels and associated with lymph node metastasis and parametrium invasion but not predictive of recurrence and survival in cervical cancer patients.
