Project description:Androgen deprivation therapy (ADT) is a cornerstone treatment for locally advanced or metastatic prostate cancer (PCa). However, its potential effects on the tumor immune microenvironment (TIM) of PCa patients and the underlying mechanism remain largely unclear.We used RNA sequencing to reveal the effects of ADT on the PCa TIM at the transcriptome level. RNA sequencing was performed on 6 paired pre-ADT biopsy and post-ADT PCa lesions and 5 paired paracancerous benign tissues from patients receiving neoadjuvant ADT with locally advanced PCa.
Project description:Purpose: The goals of this study is to compare NGS-derived Androgen Deprivation Therapy (ADT) resistant miRNome profiling to Androgen Deprivation Therapy (ADT) sensitive miRNome profile in African American prostate cancer cells and validate by reverse transcription polymerase chain reaction (qRT–PCR) methods. Method: Mirco-RNA were isolated from different CaP cells who were sensitive and resistant to Androgen Deprivation Therapy (ADT). Total micro-RNA were subjected to miRNA-Seq. Results: We performed whole miRNA-Seq analysis through paired-end deep sequencing to systematically investigate the molecular features of different CaP cell models- RC-77-N, RC-77T/E, RCC7T/E-ADT, RCC7T/E-CD133-plus, E006AA-hT and E006AA-hT-ADT. Conclusions: Our study represents the first detailed analysis of African American ADT resistant miRNome, with biologic replicates, generated by miRNA-seq technology.
Project description:Men with clinically localized prostate cancer were treated with 0 to 9 months of neoadjuvant hormone suppression prior to prostatectomy. Keywords: microarray, hormone, 9 men with prostate cancer were assigned to neoadjuvant hormone suppression therapy for 3-6, 6, or 0 months.
Project description:The aim of this research was to identify miRNAs that are associated with neoadjuvant hormonal therapy resisitance in prostate cancer.

Project description:Purpose: The goals of this study are to compare NGS-derived Androgen Deprivation Therapy (ADT) resistant transcriptome to profiling (RNA-seq) to Androgen Deprivation Therapy (ADT) sensitive transcriptome in African American prostate cancer cells and validate by reverse transcription polymerase chain reaction (qRT–PCR) methods. Method: Total RNA was extracted from different CaP cell who were ADT sensitive and ADT resistance. Total RNA was subjected to whole transcriptome sequencing analysis. Sequence reads Results: We performed whole transcriptome RNA-Seq analysis through paired-end deep sequencing to systematically investigate the molecular features of different CaP cell models- RCC7/N, RCC7T/E, RCC7T/E-ADT, RCC7T/E-CD133, E006AA-hT and E006AA-hT-ADT We obtained an average of 23.85 million reads per sample, ranging from 22.86 to 24.93 million reads, with an average mapping rate of 98.29% to the reference human genome (UCSC version hg20). Next we performed Kal’s Z-test and generated Fold-Change (FC) values, p values and False Discovery Rate (FDR) values for measuring comparative gene expression profile. By applying stringent statistical threshold of greater than or equal to 2 FC, p value < 0.05 and FDR value < 1, we identified genes that were significantly differentially expressed in three different comparative groups. Conclusions: "Our study represents the first detailed analysis of African American ADT resistant transcriptomes, with biologic replicates, generated by RNA-seq technology. The optimized data analysis workflows reported here should provide a framework for comparative investigations of expression profiles. Our results show that NGS offers a comprehensive and more accurate quantitative and qualitative evaluation of mRNA content within a cell or tissue. We conclude that RNA-seq based transcriptome characterization would expedite genetic network analyses and permit the dissection of complex biologic functions. "
