Project description:The study goal is to identify the gene expression profile of iBAT-related ganglia (SG/T1 & T3) and iWAT-related ganglia (T13/L1 & L2). RNA sequencing demonstrated clear separation of gene expression between brown adipose tissue related ganglia (SG and T3) and white adipose tissue related ganglia (T13/L1 and L2). Each sample type also showed clear separation from each other. No significant separation was observed in different genders.
Project description:To subtype the Triple gene knockout tumor we generated and assess the similiarities with widely used MB49 cells, TKO cells were injected into bladder wall orthtopically and bladder lumen by catheter intravesically in C57 BL/6J, while MB49 intravesical injection as a control. TKO intravesical tumors, TKO orthotopic tumors and MB49 intravesical tumors were collected and sent for RNA-seq analysis. In results, both intravesical TKO and orthotopic TKO tumors demonstrates transcriptome profiles that closely resembled human basal like muscle invasive bladder cancer using a luminal/basal/neuronal classifier. Principal Component Analysis (PCA) across samples demonstrated that MB49 cells had transcriptome profiles that differed significantly from TKO tumors. Hence, this study suggest that the TKO tumors closely resemble basal like human bladder cancer and MB49 exhibited no expression of urothelial markers.
Project description:Purpose: The goal of this study to examine mRNA transcriptomic changes in reward-related brain regions of subjects with alcohol use disorder. Methods: Total RNAs were extracted from postmortem nucleus accumbens of 12 AUD and 12 control subjects. rRNA depletion RNA sequencing was performed and the sequence reads were processed using the bulk RNA-seq processing pipeline Pipeliner workflow (Federico et al. Front Genet 2019; 10, 614). AUD-associated mRNA transcriptomic changes were analyzed by the Limma-Voom method. Results: Differentially expressed mRNAs (absolute FC>2.0 & P<0.05) were identified in postmortem nucleus accumbens of subjects with alcohol use disorder (AUD). Chronic alcohol consumption may alter mRNA transcriptome profiles in reward-related brain regions, resulting in alcohol-induced neuroadaptations.
Project description:Using microRNA-Seq, we examined the alteration of microRNA expression profiles in the nucleus accumbens of methamphetamine-sensitized and saline-control mice. Nucleus accumbens lysate from eight mice of each group were pooled as one sample. Two RNA samples from each group were prepared and were then processed to generate small RNA libraries, which were sequenced on the Illumina Hiseq 2000. The aberrant expression of microRNAs identified in this study may involve in METH-induced locomotor sensitization and addiction.
