Project description:Frankincense oil is prepared from aromatic hardened wood resin obtained by tapping Boswellia trees. For thousands of years, it has been important both socially and economically as an ingredient in incense and perfumes. Frankincense oil is a botanical oil distillate made from fermented plants that contains boswellic acid, a component known to have anti-neoplastic properties. We evaluated frankincense oil-induced cytotoxicity in bladder cancer cells. With a window of concentration, frankincense oil suppressed cell viability and induced cytotoxicity in bladder transitional carcinoma J82 cells but not normal bladder urothelial UROtsa cells immortalized with SV40 large T antigen. However, frankincense oil-induced J82 cell death did not result in DNA fragmentation. Microarray and bioinformatics analysis confirmed that frankincense oil activated cell cycle arrest, suppressed cell proliferation, and activated apoptosis in J82 cells through a series of potential pathways. These finding suggest that bladder cancer can be treated through intravesical administration of pharmaceutical agents similar to direct application on melanoma. 2E05 J82 cells were untreated or treated with a 1/1000 dilution of frankincense oil for 0.5, 1, 2, or 3 hours prior to RNA extraction.

Project description:Uropathogenic Escherichia coli (UPEC) are the most common cause of urinary tract infection (UTI). UPEC normally reside in the intestine, and during establishment of UTI, it undergoes metabolic adaptations, first to urine and then upon tissue invasion to the bladder cell interior. In order to understand these adaptations, we used quantitative proteomic profiling to characterize protein expression of UPEC strain UTI89 growing in human urine and when inside J82 bladder cells. In order to facilitate detection of UPEC proteins over the excess amount of eukaryotic proteins in bladder cells, we developed a method where proteins from UTI89 grown in MOPS and urine was spiked-in to enhance detection of bacterial proteins. More than 2000 E. coli proteins were detected. During growth in urine, proteins associated with iron acquisition and several amino acid uptake and biosynthesis systems, in particular arginine metabolism, were significantly upregulated. During growth in J82 cells, proteins related to iron uptake and arginine metabolisms were upregulated together with proteins involved in sulphur compound turnover. Results suggested that UPEC experience a richer environment in bladder cells compared to urine. There was no direct correlation between upregulated proteins and proteins reported to be essential for infections, showing that upregulation during growth does not signify that the proteins are essential for growth under a condition.

Project description:Cholesterol is essential for membrane biogenesis, cell proliferation and differentiation. The role of cholesterol in cancer development and the regulation of cholesterol synthesis are still under active investigation. Here we show that under normal-sterol conditions，p53 directly represses the expression of SQLE, a rate-limiting and the first oxygenation enzyme in cholesterol synthesis，in a SREBP2-independent manner. Through transcriptional downregulation of SQLE, p53 represses cholesterol production in vivo and in vitro, leading to tumor growth suppression. Inhibition of SQLE using small interfering RNA (siRNA) or terbinafine (a SQLE inhibitor) reverses the increased cell proliferation caused by p53 deficiency. Conversely, SQLE overexpression or cholesterol addition promotes cell proliferation, particularly in p53 wild-type cells. More importantly, pharmacological inhibition or shRNA-mediated silencing of SQLE restricts nonalcoholic fatty liver disease (NAFLD) -induced liver tumorigenesis in p53 knockout mice. Therefore, our findings reveal a role for p53 in regulating SQLE and cholesterol biosynthesis, and further demonstrate that downregulation of SQLE is critical for p53-mediated tumor suppression.

Project description:To investigate gene expression profile changes after ANLN knockdown, we have employed whole genome microarray expression profiling as a discovery platform to identify genes that altered after ANLN knockdown, so as to explore the potential function of ANLN. Bladder cancer cell line J82 was knocked down by using small interfering RNA (siRNA) or control siRNA 24, 48 and 72 hours, respectively.

Project description:Background: Frankincense (Ru Xiang) and sandalwood (Tan Xiang) are ingredients used in traditional Chinese medicine, and have been recognized as cancer preventive and therapeutic agents. Hydrodistillation of frankincense gum resins and sandalwood heartwood to prepare essential oils is a method to extract biologically active ingredients from these plant-derived products. This study was designed to differentiate frankincense (Boswellia carterii) and sandalwood (Santalum album) induced anti-proliferative and pro-apoptotic activities in cultured human bladder cancer cells. Methods: Frankincense and sandalwood essential oils-mediated cytotoxicity was studied in established human bladder cancer J82 cells and immortalized normal human bladder urothelial UROtsa cells using a colorimetric assay. Essential oils-activated gene expression and pathway activation in human bladder cancer J82 cells were identified using high density microarray and bioinformatics techniques. Results: Human bladder cancer cells were more sensitive to immortalized normal bladder cells with suppressed viability following frankincense essential oil exposure. In contrast, both cancerous and normal bladder cells responded to sandalwood essential with similar levels of cytotoxicity. Based on microarray and bioinformatics analyses, genes responsible for suppressing biological processes and apoptosis were induced in J82 cells by both essential oils. Although both frankincense and sandalwood essential oils activated common ontologies and canonical pathways leading to suppressed J82 cell viability and apoptosis, each essential oil had unique property on these cells. For example, heat shock proteins and histone core were ongologies regulated by frankincense essential oil, whereas transcription regulation and G-protein couple receptor were ontologies unique to sandalwood essential oil treatment. In addition, NRF-2 mediated oxidative stress was implicated as the primary cause of frankincense essential oil-induced J82 cell death; in contrast, DNA damage and cell cycle arrest might be attributed to sandalwood essential oil-mediated cytotoxicity. Conclusion: Based on cell biology and comprehensive gene expression analysis, our results provide a preliminary, yet focused characterization of genetic responses to frankincense and sandalwood essential oils with respect to their proposed anti-neoplastic properties. Modern biomedical technologies are powerful tools to study biological responses following treatments with traditional Chinese medicine, which always consist of complex chemical constituents. To differentiate mechanisms of frankincense and sandalwood essential oils induced cytotoxicty in bladder cancer J82 cells, time-dependent transcriptoms expression was performed in cultured cells following essential oils treatments
