additional information | construction of SULT2B1b knockdown prostate cells using siRNA or shRNA targeting and LNCaP cells. SULT2B1b knockdown results in a decrease in growth/viability of LNCaP, VCaP, C4-2, and RWPE-1 cells as well as decreased softagar colony formation in LNCaP cells, and it induces cell death in prostate cancer cells. A significant decrease in cell growth/viability is observed using multiple SULT2B1b RNAi sequences in LNCaP cells. SULT2B1b knockdown increases the percentage of sub-G1 nuclei by cell-cycle analysis and significantly increased caspase-3 activity and PARP cleavage in LNCaP, VCaP, and C4-2 cells. LNCaP cells with SULT2B1b knockdown analyzed by flow cytometry show an increased percentage of Annexin V+/propidium iodide (PI)x02cells compared with control cells. Double KD of SULT2B1b/LXRbeta does not affect the siRNA knockdown efficiency compared with SULT2B1b or LXRbeta knockdown alone. LNCaP cells with SULT2B1b overexpression (hSULT2B1b vector) show a significant decrease in liver X receptor (LXR) activity and a trend of decreased transcription of downstream target gene, ATP-binding cassette (ABC)-G1. LXR activity in LNCaP cells has been demonstrated to be due to transcriptional activation of LXRbeta. Phenotype of SULT2B1b knockout cells, overview | Homo sapiens |

malfunction | SULT2B1b knockdown induces cell death in prostate cancer cells. SULT2B1b knockdown increases the percentage of sub-G1 nuclei by cell-cycle analysis and significantly increased caspase-3 activity and PARP cleavage in LNCaP, VCaP, and C4-2 cells. Targeted knockdown of SULT2B1b impairs growth/viability of prostate cancer cells and induces apoptosis. LNCaP cells with SULT2B1b overexpression (hSULT2B1b vector) show a significant decrease in liver X receptor (LXR) activity and a trend of decreased transcription of downstream target gene, ATP-binding cassette (ABC)-G1. LXR activity in LNCaP cells has been demonstrated to be due to transcriptional activation of LXRbeta | Homo sapiens |
physiological function | role of SULT2B1b in the growth and progression of cancer cells. Cholesterol sulfate accumulation correlates with SULT2B1b expression in prostate cancer cells and human prostate specimens. SULT2B1b activity modulates androgen receptor (AR) activity in prostate cancer cells, SULT2B1b is a regulator of AR activity and cell growth in prostate cancer | Homo sapiens |
