Project description:Proteinuria is pathogenic to proximal tubular cells (PTC) and linked with progression to renal failure. Angiotensin II (AngII) is also independently involved in the pathogenesis of progressive renal injury in varied kidney disease. The effects of human serum albumin (HSA) overload, AngII and candesartan, a specific inhibitor of AngII type 1 recptor, on the changes in gene protein expression stimulated by oxidative stress in PTC were assesed using cDNA microarrays. Keywords: stress response Cells were growth arrested for 48 h in serum-free DMEM/Ham's F-12 medium with 5.5 mM glucose, 2 mM L-glutamine,100 U/ml penicillin, 100 ug/ml streptomycin, 20 mM Hepes. Media were refreshed and cells were incubated for 24h in conditioned media alone, or with media supplemented with 30mg/ml of different HSA preparations, 1 uM AngII or AngII in the presence of candesartan. After further 24 h under standard cell culture conditions (37C, 5% CO2) cells were subjected to RNA extraction.

Project description:In this study, the effect of a storage medium (hK-HTCM) in which hair keratin was dissolved in a 1:1 mixed solution of Histidine-Tryptophan-Ketoglutarate and Culture media solution (HTCM) was evaluated on the viability and proliferation of human periodontal ligament cells. There was no difference in cytotoxicity between 0.1% and 0.25% hK-HTCM against 0% hK-HTCM and human periodontal ligament cells. Human periodontal ligament cells were cultured in 0.1% and 0.25% hK-HTCM for 48 hours, and after removing hair keratin from the culture medium, the cells resumed proliferation. When exposed to 0.25% hK-HTCM, human periodontal ligament cells showed differential expression of genes related to cell cycle and cell division regulation. On the other hand, differential expression of genes related to phosphorylation and ubiquitination related to cell cycle resumption was observed in human periodontal ligament cells after removal of 0.25% hK-HTCM. 0.25% hK-HTCM showed the ability to regulate the cell cycle of human periodontal ligament cells without showing cytotoxicity, and its potential to be used as a long-term storage medium for avulsed teeth was confirmed.

Project description:Aim： Use microarray analysis to understand the molecular mechanism underlying the effect of aristolochic acid (AA), a major active component of plants from the Aristolochiaceae family, in normal human kidney (HK-2) cells. Methods： HK-2 cells were treated with AA for 24 hours and cell viability was measured by a 3-(4,5-dimethylthiazol-2yl)-2,5-diphenyltetrazolium bromide assay. Complementary DNA microarrays were used to investigate the gene expression pattern of HK-2 cells exposed to AA and the results of this study were in triplicate. Quantitative real-time RT-PCR assay was used to verify the microarray data for selected nuclear factor kappa B (NF-κB)-regulated genes. Furthermore, subcellular localization of NF-κB p65 was visualized by immunofluorescence confocal microscopy in HK-2 cells. NF-κB activity was examined by luciferase reporter assay in HK-2/NF-κB transgenic cells. Results： AA exhibited a dose-dependent cytotoxic effect in HK-2 cells and induced alterations in gene expression profiles related to DNA damage response, stress response, etc. In addition, 9 biological pathways associated with immunomodulatory functions were down-regulated in AA-treated HK-2 cells. Network analysis revealed that NF-κB played a central role in the network topology. Among NF-kB-regulated genes, 8 differentially expressed genes were verified by real-time RT-PCR. The inhibition of NF-κB activity by AA was further confirmed by immunofluorescence confocal microscopy and by NF-κB luciferase reporter assay. Conclusion： Our data revealed that AA could suppress NF-κB activity in normal human cells, perhaps partially accounting for the reported anti-inflammatory effects of some plants from the genus Aristolochia. HK-2 cells were grown in keratinocyte serum-free basal medium (Gibco) supplemented with 5 ng/ml of recombinant epidermal growth factor and 50 μg/ml of bovine pituitary extract without antibiotics in 5 % CO2 at 370C. HK-2 cells were seeded in 25-T flasks and incubated for 24 h before aristolochic acid treatment. Aristolochic acid (10 90 μM) were added to HK-2 cells for 24 h. The control cells received equal amounts of water only.
