This study aimed to identify specific transcriptomic signatures in GBC, HCC, and ICC.

Prognostic role of Androgen Receptor splice variant 7 (AR-V7) in the pathogenesis of breast cancer.

Background: The Androgen Receptor (AR) has emerged as an endocrine therapy target in Breast Cancer, exhibiting up to 80% expression in clinical cases. AR-V7, a constitutively activated splice variant of AR with a truncated ligand-binding domain (LBD), demonstrates ligand-independent transcriptional activity and resistance to nonsteroidal antiandrogens like Bicalutamide or Enzalutamide, targeting the LBD. In metastatic prostate cancer, elevated AR-V7 levels lead to therapeutic resistance and increased metastasis.
