Web15 de out. de 2002 · Abstract. Prostate cancer (PCa) begins as an androgen-dependent tumor that will eventually progress to an androgen-independent stage after androgen ablation. Although little is understood about this transition to androgen independence, the androgen receptor (AR) appears to be involved. The coactivator p300 has been shown … Web25 de fev. de 2024 · Throughout this pathway, the factor-inhibiting HIF-1 α is a negative regulator of HIF-1 α leading to its hydroxylation at the C-TAD domain of HIF-1 α under normoxia. Thus, hydroxylated HIF-1 α is unable to proceed with the transcriptional events due to interference in binding of C-TAD and CBP/p300. frisée salad with bacon vinaigrette
