Project description:Chrysin has been reported to have anticancer effect. We used 40μM chrysin to treat SGC7901 cells for 48h, then sequenced their RNA, analyzed the differentially expressed genes before and after treatment, screened out the anticancer target of chrysin, and then carried on the next analysis

Project description:There is no known single therapeutic drug for treating hypercholesterolemia that comes with negligible systemic side effects. In the current study, using next generation RNA sequencing approach in mouse embryonic fibroblasts we discovered that two structurally related flavonoid compounds, Apigenin and Chrysin exhibited moderate blocking ability of multiple transcripts that regulate rate limiting enzymes in the cholesterol biosynthetic pathway. The observed decrease in cholesterol biosynthesis pathway correlated well with an increase in transcripts involved in generation and trafficking of ketone bodies as evident by the upregulation of Bdh1 and Slc16a6 transcripts. Impact statement - The hypocholesterolemic potential of Apigenin and Chrysin at higher concentrations along with their ability to generate ketogenic substrate especially during embryonic stage is useful or detrimental for embryonic health is not clear and still debatable. Our findings will set the stage for translating this information to whole animal and clinical studies that could shed light to the existing information regarding safe use of Apigenin and Chrysin, specifically to embryonic health.

Project description:Pulmonary arterial hypertension (PAH) is a debilitating progressive disease characterized by high blood pressure in the pulmonary artery. Chrysin (5,7-dihydroxyflavone) is a phytochemical, which is a flavonoid widely present in plant sources. It is known that right ventricular dysfunction is the worst mortality predictor in patient with PAH. Recent studies have shown that chrysin improves hemodynamic parameters including right ventricular pressure, right ventricular hypertrophy, and pulmonary vascular remodeling in a rat model of chronic hypoxia-induced pulmonary hypertension. On the other hand, trimetazidine (TMZ) is an anti-ischemic agent widely used in the treatment of coronary artery disease. It has been reported that trimetazidine therapy for 3 months on top of standard PAH regime significantly improve right ventricular ejection fraction and functional capacity in patient with PAH. However, the effects of chrysin or trimetazidine on gene expression in lung of patient with PAH. Here, we performed that a comprehensive analysis of gene expression changes in lung tissues of sugen-received rats under hypoxic conditions, which is a model of PAH with chrysin or trimetazidine treatment using RNA sequencing (RNA-seq).

Project description:As a humanized mouse antibody, SM5-1 can target a membrane protein of about 230kDa over-expressed in hepatocellular carcinoma (HCC), melanoma and breast cancer and it has been found to inhibit the progress of tumor cells. In this study, SM5-1 conjugated gold nanoparticles were prepared to study the antitumor efficacy in the treatment of HCC-LM3-fLuc tumor. The results showed that AU-SM5-1 could inhibit HCC-LM3 hepatocellular carcinoma cell proliferation up to 71.26% at the concentration of 0.5mg/ml contrast with SM5-1 and gold nanoparticles. In order to address the mechanism of the antiproliferative effects of AU-SM5-1, we examined the gene expression in HCC-LM3-fLuc tumor cells based on gene-chip screening. The gene chip results showed that some cycle-related and reactive oxygen species (ROS) related genes including up-regulated P21 and down-regulated duox2 and nox1 genes which were validated by real-time quantitative polymerase chain reaction (PCR).

Project description:Pulmonary arterial hypertension (PAH) is a progressive disease characterized by pulmonary vascular remodeling leading to increased pulmonary vascular resistance and right ventricular (RV) hypertrophy, resulting in RV failure. RV dysfunction is a complex process that leads to cardiomyocyte hypertrophy, fibrosis, inflammation, angiogenesis, and metabolic changes. In patient with PAH, the adaptation of the RV to high pulmonary arterial pressures is the most important determinant of prognosis. However, the underlying molecular mechanism of adverse RV remodeling and dysfunction is poorly understood, and there are no currently approved therapies that improve RV function. Chrysin (5,7-dihydroxyflavone) is a phytochemical, which is a flavonoid widely present in plant sources. In various experimental models chrysin has shown to exert cardio-protective effects through its antioxidant and anti-inflammatory effects. In this study, we performed a comprehensive analysis of gene expression changes in heart tissues of rats under hypoxic conditions with chrysin treatment using RNA sequencing (RNA-seq).

Project description:Dynamic changes in RNA and protein levels after exposure to 100µmol/L nimesulide and low-dose 0.5µmol/L cisplatin in oral cancer cells were screened to gain insights into the molecular mechanisms of cell death. After 48 hours of treatment, SCC9 and SCC25 cells were analyzed for apoptosis and necrosis by FACS, immunohistochemistry and analysis of nucleotides by HPLC. Microarray GeneChips and the iTRAQ system were used to measure changes in the whole genome and proteome. FACS and immunohistochemical analyses showed an increased number of apoptotic and necrotic SCC9 and SCC25 cells after nimesulide and cisplatin exposure. Simultaneously, ATP and the energy charge of the SCC9 cells were significantly decreased. In SCC25 cells, ATP only significantly decreased after combined nimesulide/cisplatin exposure. In the SCC9 cell line, gene and proteome analysis detected and quantified one gene, keratin 6a and 540 proteins, respectively. After combined treatment, significant upregulation of histone H2A, H2B and H4 could be found with a local discovery false rate of 0.003 and 0.0027 for histone H2A and histone H2B, respectively. Using gene and proteome mapping, we could show that combined treatment of oral cancer cells with nimesulide and low-dose cisplatin induce necrosis and early apoptosis by the intrinsic and extrinsic pathways. Our results suggest potential clinical benefits of a nimesulide/cisplatin combination rather than single cisplatin treatment for oral cancer patients. Cell culture: A squamous carcinoma cell line of the tongue, SCC9, was obtained from the American Type Culture Collection (ATCC, Rockville, Maryland, USA). The cell line was cultured in RPMI 1640 medium containing 10% fetal bovine serum and 100U/mL penicillin and 100µg/mL streptomycin (all reagents from Life Technologies Ltd, Paisley, Scotland) and incubated at 37°C in a humidified atmosphere of 5% CO2. SCC9 cells were maintained in RPMI 1640 medium and seeded at equal densities of 5x10^5 cells in 10cm tissue culture dishes. 24 hours later, cells were harvested using Trypsin/EDTA (Life Technologies Ltd, Paisley Scotland) and treated with 100µmol/L nimesulide, 0.5µmol/L cisplatin or a combination of nimesulide/cisplatin. Control dishes were treated in exactly the same way without the addition of the respective compound. The concentration of 100µmol/L for nimesulide was chosen as this concentration is in a pharmacologically relevant range for humans. cDNA microarray, hybridization and image analysis: RNA isolation and preparation of cRNA, hybridization, and scanning of the arrays were performed according to protocols of the manufacturer. Hybridization was done using three sets of human U133A GeneChips (Affymetrix, Ca, USA); only two nimesulide/cisplatin Samples are included in this submission. The arrays were scanned using the GeneArray scanner (Affymetrix). Data normalization was performed using RMA. The supplementary file 'GSE15308_sample_protocols.txt' contains detailed Sample protocols.
