Project description:RNA-Seq analysis of prostate cancer cell line LNCaP treated with vehicle (C), androgen (R), androgen and IMTPPE (R + IMTPPE), androgen and JJ-(+)-450 (androgen + (-)450), androgen and JJ-(-)450 (androgen + (-)450), androgen and enzalutamide (androgen +Enz). To evaluate if our compounds can inhibit AR function specifically and completely, LNCaP mRNA profiles of cells treated with IMTPPE, (+)-JJ-450 and (-)-JJ-450, comparing to enzalutamide. RNA isolation was performed using RNeasy Mini kit (Qiagen), RNA Sequencing was carried out by Genomics Research Core of University of Pittsburgh using Illumina NextSeq 500 system. The sequence reads that passed FASTQC were analyzed at the transcript level. Each sample was mapped to the Human Ensembl reference genome GRCh38. We definied different expression genes with a fold change ≥2.0 and FDR <0.05. Both (-)-JJ-450 and enzalutamide are very specific to AR, with 56 and 186 DE genes comparing to control samples respectively. IMTPPE and (+)-JJ-450 can inhibit most of the androgen responsive genes, but also some other genes were affected. (-)-JJ-450 is a novel compound inhibts AR function specifically and completely, and it is a potential lead compound for the treatment of CRPC, including those resistant to enzalutamide.
Project description:Investigation of whole genome gene expression level in motile strain of Sphingomonas. sp A1 All flagellar genes in motile strain of Sphingomonas. sp A1 are highly transcribed.
Project description:The survival, pollutant degradation activity and transcriptome response was monitored in Sphingomonas sp. LH128 inoculated into soil. Cultivable cell numbers were determined by plating, while phenanthrene degradation was monitored by HPLC. The genetic base for the adaptive strategy of LH128 in soil was investigated by using microarray consisting 7,200 gene-coding ORFs. During 4 hours of incubation, 510 genes were differentially expressed (317 increased and 193 reduced expression) while 610 genes were differentially expressed (318 increased and 292 reduced) after 10 days of incubation. Genes with increased expression comprised of gene encoding PAH catabolic enzymes, stress resistance, oxidative stress tolerance, outer membrane proteins/porins and efflux pump proteins while the downregulated genes comprised of genes encoding flagellar biosynthesis, ribosomal proteins and ATPase.
