WebSep 15, 2011 · We treated human CRPC xenografts with abiraterone and measured tumor growth, tissue androgens, androgen receptor (AR) levels, and steroidogenic gene expression versus controls. Results: WebPSP and PSPS specifically enrich in PSMA+ CRPC xenografts in vivo. Both ICG-labeled-PSP and PSPS diffused throughout the entire body including the tumor tissues 6 h after the injection as detected by FLI. ICG-labeled-PSP and PSPS were then steadily cleared but were still retained in PSMA+ tumor tissues even 96 h post-injection (Figure 4A&4C).

WebOct 26, 2024 · We utilized CRPC models to identify DDX3:AR mRNA complexes by RNA immunoprecipitation, assess the effects of DDX3 gain/loss-of-function on AR expression and signaling, and address clinical implications of targeting DDX3 by assessing sensitivity to AR-signaling inhibitors (ARSI) in CRPC xenografts in vivo. ARL/− CRPC expressed … WebIn vivo, SINT1 caused regression of CRPC xenografts and reduced expression of prostate-specific antigen, a gene transcriptionally regulated by AR. Inhibition of AR activity by SINT1 was additive to EPI-002, a known AR AF-1 inhibitor that is in clinical trials (NCT02606123). This implies that SINT1 binds to a site on AF-1 that is unique from EPI. gentrification and racial inequality
