Hyperlipidemia adversely affects bone metabolism, often resulting in compromised osseointegration and implant loss. In addition, genetic networks associated with osseointegration have been proposed. Serologically defined colon cancer antigen 3 (Sdccag3) is a novel endosomal protein that functions in actin cytoskeleton remodeling, protein trafficking and secretion, cytokinesis, and apoptosis, but its roles in the osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) and in implant osseointegration under hyperlipidemic conditions have not been uncovered. Here, we performed microarray and RNA sequencing analysis to determine the differential expression of the Sdccag3 gene and related noncoding RNAs (ncRNAs) and to assess the long noncoding RNA (lncRNA) MSTRG.97162.4-miR-193a-3p-Sdccag3 coexpression network in bone tissues within the region 0.5 mm around implants in hyperlipidemic rats. In this experiment, we found that Sdccag3 and the previously uncharacterized lncRNA-MSTRG.97162.4 were downre-fold; BIC%, 1.26-fold). Therefore, our findings show that Sdccag3 promotes implant osseointegration, and its related lncRNA-MSTRG.97162.4 and miR-193a-3p play an important role in osseointegration during hyperlipidemia, which might be a promising therapeutic target for improving dental implantation success rates.Using multiple imaging modalities while performing independent experiments in parallel can greatly enhance the throughput of microscopy-based research, but requires provision of appropriate experimental conditions in a format that meets the microscopy's optical requirements. Although customized imaging chambers can meet these challenges, the difficulty of manufacturing custom chambers and the relatively high cost and design inflexibility of commercial chambers has limited the adoption of this approach. Herein, we demonstrate the use of 3D printing to produce inexpensive, customized live-cell imaging chambers that are compatible with a range of imaging modalities including super-resolution microscopy. In this approach, biocompatible plastics are used to print imaging chambers designed to meet the specific needs of an experiment, followed by adhesion of the printed chamber to a glass coverslip, producing a chamber that is impermeant to liquids and which supports the growth and imaging of cells over multiple days. This approach can also be used to produce moulds for casting PDMS microfluidic devices. The utility of these chambers is demonstrated using designs for multiplex microscopy, imaging under shear, chemotaxis, and general cellular imaging. Together, this approach represents an inexpensive yet highly customizable approach to produce imaging chambers that are compatible with modern microscopy techniques.PURPOSE To characterize the aqueous levels of inflammation and ischemia related biomarkers in a spectrum of retinal ischemic conditions, including neovascular glaucoma (NVG) with stable iris neovascularization after pan retinal photocoagulation (PRP) and anti-VEGF treatment. METHODS Aqueous samples were collected from 139 eyes including NVG (n=12), stable NVG (n=26), CRVO (n=11), NPDR (n=18), PACG (n=18), PDR (n=25), BRVO (n=7) and cataract (n=22). The levels of VEGF-A, IL-8 and EPO were measured with ELISA. RESULTS Aqueous VEGF-A significantly decreased after anti-VEGF and PRP, from 983.79 ± 821.16 pg/ml in the NVG group (n = 11) to 256.50 ± 51.14 pg/ml in the stable NVG group (n = 24) (P= 0.015). Aqueous VEGF-A in stable NVG group (256.50 ± 51.14 pg/ml, n=24) was significantly higher (ANOVA, P less then 0.001) than in CRVO (212.10±19.84 pg/ml, n=7, P = 0.017), NPDR (221.18±38.21 pg/ml, n=14, P = 0.015), BRVO (213.14±48.50 pg/ml, n=6, P = 0.028) and cataract group (185.30±34.35 pg/ml, n=22, P less then 0.001). Aqueous IL-8 in stable NVG group (74.82±10.78 pg/ml, n=24) was significantly higher (ANOVA, P less then 0.001) than in CRVO (65.19±15.34 pg/ml, n=11, P = 0.032) and cataract group (54.11±12.28 pg/ml, n=22, P less then 0.001). Aqueous EPO in stable NVG group (17.48±3.02 pg/ml, n=24) was significantly higher (ANOVA, P less then 0.001) than in BRVO (14.98±2.57 pg/ml, n=7, P = 0.034) and cataract group (13.50±2.65 pg/ml, n=22, P less then 0.001). Aqueous concentrations of VEGF-A and IL-8 correlated positively with IOP (r=0.413, P less then 0.001, r=0.349, P less then 0.001, respectively, r=correlation coefficient). VEGF-A correlated positively with IL-8 and EPO (P less then 0.001, P= 0.002, respectively). find more IL-8 correlated positively with EPO (P less then 0.001). CONCLUSIONS The aqueous levels of VEGF-A, IL-8 and EPO in NVG patients with stable iris neovascularization, who had received PRP and anti-VEGF, were still significantly higher than in control groups with some retinal ischemic conditions.Photodynamic therapy (PDT) has demonstrated encouraging anticancer therapeutic results, but the current clinically approved photosensitizers (PSs) are not ideal in the treatment of bladder cancer. Conventional PSs have low selectivity to the bladder tumor tissue and induce toxicity or bystander effects on nontumor urothelium. Previous studies demonstrated that the use of galactose-photosensitizer (PS) conjugates is a more selective method of delivering PDT-mediated toxicity due to their ability to recognize carbohydrate-binding domains overexpressed in bladder tumors. Using patient-derived bladder tumor specimens cultured ex vivo and bladder cancer cell lines with different PDT sensitivity, we find that a galactose-phthalocyanine (PcGal16) accumulates in bladder tumors expressing galactose-binding proteins and internalizes through an endocytic process. The endocytosis mechanism is cell line-dependent. In HT-1376 bladder cancer lines resistant to PDT, depletion of caveolin-1-the main structural protein of caveolae structures-increased the amount of sugar-binding proteins, i.e. GLUT1, at the cell membrane resulting in an improved PcGal16 uptake and PDT efficacy. These data show the potential of ex vivo cultures of bladder cancer, that ideally could mimic the original microenvironment, in screening galacto-PDT agents. Additionally, our studies demonstrate that PDT efficacy in bladder cancer depends on the endocytic mechanisms that regulate PS accumulation and internalization in cancer cells.
