J82 human bladder cell line treated with frankincense oil

ABSTRACT: 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.

<h4>Background</h4>Originating from Africa, India, and the Middle East, frankincense oil has been important both socially and economically as an ingredient in incense and perfumes for thousands of years. Frankincense oil is prepared from aromatic hardened gum resins obtained by tapping Boswellia trees. One of the main components of frankincense oil is boswellic acid, a component known to have anti-neoplastic properties. The goal of this study was to evaluate frankincense oil for its anti-tumor a ...[more]

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

Project description:Some studies have shown that acute intake of high-phenol virgin olive oil reduces pro-inflammatory, pro-oxidant and pro-thrombotic states, but nowadays still remains unclear if those effects attributed to its phenolic fraction could be exerted at transcriptional level in vivo. Two virgin olive oil-based breakfasts with high (398 ppm) and low (70 ppm) content of phenolic compounds were administered to twenty patients (9 men and 11 women) with metabolic syndrome following a double-blinded random crossover design. Prior to the first breakfast intervention, participants followed a 6-week washout period in which they were instructed to not take vitamins, soy supplements, or any drug. To eliminate the potential effect that might exist in their usual dietary habits, all subjects followed a low-fat, carbohydrate rich (CHO) diet during this period and untill the end of the study. In the 24 h before each breakfast intervention, participants were instructed to avoid consuming phenol-rich foods such as fruit or juices, wine, grape juice, chocolate, coffee, tea, olive oil, or soya, and to refrain from intense physical exercise during that period. After a 12 h fasting and following a randomized sequential crossover design with one-week washout period, participants reported to the hospital and received two fat meals consisting of 60 g of white bread, 40 mL of VOO (CANOLIVA®, Antonio Cano e Hijos™, Córdoba, Spain) with high (398 ppm) or low (70 ppm) content in phenolic compounds, and 60,000 IU of vitamin A per m2 of body surface. Olive oil with low content in phenolic compounds was obtained as a result of extraction by physical procedures of most of the phenolic compounds in the high-phenol olive oil, so that both oils kept a similar composition of the remaining macro- and micronutrients. Throughout the 4-h duration of the study, the subjects performed no physical activity, nor did they consume anything but water. Gene expression was performed on peripheral blood mononuclear cells (PBMCs) at postprandial period (4 hours after breakfast) by microarray analysis and verified by qRT-PCR. Two sets of dye-swaped experiments were performed making a total of four technical replicates per subject. Each of the hybridizations compared total RNA from PBMCs obtained 4h after the intake of virgin olive oil with high phenolic content vs. total RNA from PBMCs obtained 4h after low-phenol virgin olive oil consumption.

Project description:The primary goal of toxicology and safety testing is to identify agents that have the potential to cause adverse effects in humans. Unfortunately, many of these tests have not changed significantly in the past 30 years and most are inefficient, costly, and rely heavily on the use of animals. The rodent cancer bioassay is one of these safety tests and was originally established as a screen to identify potential carcinogens that would be further analyzed in human epidemiological studies. Today, the rodent cancer bioassay has evolved into the primary means to determine the carcinogenic potential of a chemical and generate quantitative information on dose-response behavior in chemical risk assessments. Due to the resource-intensive nature of these studies, each bioassay costs $2 to $4 million and takes over three years to complete. Over the past 30 years, only 1,468 chemicals have been tested in a rodent cancer bioassay. By comparison, approximately 9,000 chemicals are used by industry in quantities greater than 10,000 lbs and nearly 90,000 chemicals have been inventoried by the U.S. Environmental Protection Agency as part of the Toxic Substances Control Act. Given the disparity between the number of chemicals tested in a rodent cancer bioassay and the number of chemicals used by industry, a more efficient and economical system of identifying chemical carcinogens needs to be developed. Experiment Overall Design: Five-week old female B6C3F1 mice were exposed for 13 weeks in the following dose groups: 1) 1,5-Naphthalenediamine, CAS No. 2243-62-1, feed, 2000 ppm, positive lung carcinogen; 2) 2,3-Benzofuran, CAS No. 271-89-6, gavage, 240 mg/kg, positive lung carcinogen; 3) 2,2-Bis(bromomethyl)-1,3-propanediol, CAS No. 3296-90-0, feed, 1250 ppm, positive lung carcinogen; 4) N-Methylolacrylamide, CAS No. 924-42-5, gavage (water), 50 mg/kg, positive lung carcinogen; 5) 1,2-Dibromoethane, CAS No. 106-93-4, gavage (corn oil), 62 mg/kg, positive lung carcinogen; 6) Coumarin, CAS No. 91-64-5, gavage (corn oil), 200 mg/kg, positive lung carcinogen; 7) Benzene, CAS No. 71-43-2, gavage (corn oil), 100 mg/kg, positive lung carcinogen; 8) N-(1-naphthyl)ethylenediamine dihydrochloride, CAS No. 1465-25-4, feed, 2000 ppm, negative lung carcinogen; 9) Pentachloronitrobenzene, CAS No. 82-68-8, feed, 8187 ppm, negative lung carcinogen; 10) 4-Nitroanthranilic acid, CAS No. 619-17-0, feed, 10000 ppm, negative lung carcinogen; 11) 2-Chloromethylpyridine hydrochloride, CAS No. 6959-47-3, gavage (water), 250 mg/kg, negative lung carcinogen; 12) Diazinon, CAS No. 333-41-5, feed, 200 ppm, negative lung carcinogen; 13) Malathion, CAS No. 121-75-5, feed, 16000 ppm, negative lung carcinogen; 14) Corn oil control, gavage; 15) Water control, gavage; 16) Rodent diet control, feed. Feed animals were exposed 7 days/week and gavage animals were exposed 5 days/week (5 ml/kg). After 13 weeks, animals were euthanized and lungs were collected. The right lobe was used for microarray analysis. Microarray analysis was performed on the lungs of three to four mice per treatment group.
