GSE130395: Transcriptome profiling of prostate cancer cells on GLYATL1 knockdown

• Organsim human
• Type RNASEQ
• Target gene
• Project ARCHS4

The protein Glycine-N-Acyltransferase Like 1 (GLYATL1) is involved in detoxification of benzoate and other xenobiotics and is expressed in liver and kidney. Through In silico analysis of cancer gene expression profiling and transcriptome sequencing we revealed an overexpression of GLYATL1 in primary prostate cancer. Confirming these findings by immunohistochemistry we show that GLYATL1 is overexpressed in primary prostate cancer compared to metastatic prostate cancer and benign prostatic tissue. Low grade cancers had higher GLYATL1 expression compared to high grade prostate tumors. Our studies showed that GLYATL1 is upregulated upon androgen treatment in LNCaP prostate cancer cells which harbors ETV1 gene rearrangement. Furthermore, ETV1 knockdown in LNCaP cells showed downregulation of GLYATL1 suggesting potential regulation of GLYATL1 by ETS transcription factor ETV1. Transcriptome sequencing using the GLYATL1 knockdown prostate cancer cell lines LNCaP showed regulation of multiple metabolic pathways. In summary, our study characterizes the expression GLYATL1 in prostate cancer and explore its regulation mechanism. Future studies are needed to decipher the biological significance of these findings. SOURCE: Sooryanarayana Varambally (svarambally@uabmc.edu) - University of Alabama
