Analysis of gene expression in human malignant rhabdoid cells following prolonged treatment with the histone deacetylase inhibitor, Panobinostat

ABSTRACT: We hypothesized that prolonged treatment of malignant rhabdoid tumor cells with low-dose HDACi will drive cellular differentiation. We assessed changes in gene expression following 21 days treatment with the HDACi, Panobinostat, versus a DMSO vehcile control in three human MRT cell lines. Total RNA obtained from three human malignant rhabdoid tumor cell lines (G401, SJSC, STM91-01) cultured for 21 days in the presence of low-dose Panobinostat was compared to 21-day treated DMSO control cells. All treatments and cell lines were performed in triplicate.

Endurance training in early life results in long-term programming of heart mass in rats

Project description:This study aimed to examine if early life exercise could normalize the reduced heart mass we have previously observed in the adult hearts from growth restricted rats. We investigated the molecular pathways using microarray analysis to explain how endurance exercise in early life might be regulating the sustained increase in heart mass we have observed in these rats in adulthood. At 5 weeks of age, male WKY rats were allocated to one of the following exercise treatments: remained sedentary with post mortem (PM) at 9 or 24 weeks, early exercise training (from 5-9 weeks of age) with PM at 9 or 24 weeks, or later exercise training (from 20-24 weeks of age) with PM at 24 weeks (n=8 males/group). Exercise training involved treadmill running 5 days/ week for 4 weeks. Running duration progressively increased from 20 up to 60 minutes per day, with the treadmill speed set at 15 m/min for the first week and 20 m/min thereafter. At 9 or 24 weeks of age rats were killed with an intraperitoneal injection of Ilium Xylazil-20 (30 mg/kg) and Ketamine (225 mg/kg). The rats in the 9 week old early exercise and 24 week old later exercise groups were killed 72 hours following the last bout of treadmill running. Total RNA was obtained from the whole-hearts for analysis Total RNA obtained from the hearts of WKY rats. Male offspring remained sedentary or underwent treadmill running from 5-9 weeks (early exercise) or 20-24 weeks of age (later exercise).

RNAseq to investigate transcriptional changes in human MM cell lines due to panobinostat, 5-Azacytidine, panobinostat+5-Azacytidine or n-methyl-2-pyrroldine (NMP) treatments.

Project description:Purpose: We applied RNA sequencing technology for high-throughput analysis of transcriptional changes within human MM cell lines JJN3 and U266 due to individual and combination drug treatment. Methods: JJN3 and U266 cells were treated with pan-HDACi panbobinostat, DNMTi 5-Azacytidine, panobinostat+5-Azacytidine or NMP for 4h or 24h in triplicate and transcriptional changes assessed by RNAseq using Illumina HiSeq platform. Specifically, JJN3 cells were treated with 10nM panobinostat, 2.5µM 5-Azacytidine, panobinostat+5-Azacytidine (at given doses), or 10mM NMP. U266 cells were treated with 10nM panobinostat, 10µM 5-Azacytidine, panobinostat+5-Azacytidine (at given doses), or 10mM NMP. Results: We report unique and overlapping transcriptional signatures that lead to the induction of apoptosis in human MM cell lines in a cell-specific manner due to individual or combination treatments. Conclusions: A detailed analysis of differential transcriptional events in human MM cell lines due to HDACi, DNMTi, HDACi+DNMTi and NMP appear to define the molecular events leading to apoptosis and drug mechanism of action. We tested triplicate experiments at 4h and 24hr time points in JJN3 and U266 cell lines against vehicle control treated cells.

DNA methylation analysis of Rhabdoid tumor of the kidney, Clear cell sarcoma of the kidney and Ewing's sarcoma family of tumors

Project description:Genome wide DNA methylation profiling of Rhabdoid tumor of the kidney, Clear cell sarcoma of the kidney, Ewing's sarcoma family of tumors and non-neoplastic kidney. The Illumina Infinium HumanMethylation 27 BeadChip was used to obtain DNA methylation profiles across approximately 27000 CpGs . Samples included 3 Rhabdoid tumor of the kidney, 3 Clear cell sarcoma of the kidney, 3 Ewing's sarcoma family of tumor and 3 non-neoplastic kidney. Bisulfite converted DNA from the 12 samples were hybridized to the Illumina Infinium HumanMethylation27 Beadchip.

Aberrant chromatin acetylation in MLL-AF9 leukemia mediates the response to HDAC inhibition (microarray)

Project description:We investigated the response of acute myeloid cells (AML) expressing MLL-AF9 fusion gene to the pan-HDACi panobinostat (LBH589), and found that low conentrations of panobinostat lead to MLL-AF9 cell toxicity and rapid changes in gene expression. Human hematopoietic stem/progenitor cells (HSPC) expressing MLL-AF9 fusion protein (Wei et al, Cancer Cell 2008) were cultured with 30 nM panobinostat during 6 and 24 hours. The different gene expression between cells treated and untreated was studied by gene expression analysis. Three independent HSPC-MA9 clones were used, for each two replicates of cells after culture with 30 nM panobinostat for 6 and 24 hours and one untreated were used. A total of 16 samples were analyzed.
