Establishment and Characterization of Testis Organoids with Proliferation and Differentiation of Spermatogonial Stem Cells into Spermatocytes and Spermatids.

Organoids play pivotal roles in uncovering the molecular mechanisms underlying organogenesis, intercellular communication, and high-throughput drug screening. Testicular organoids are essential for exploring the genetic and epigenetic regulation of spermatogenesis in vivo and the treatment of male infertility. However, the formation of testicular organoids with full spermatogenesis has not yet been achieved.

Design, Synthesis, and Biological Evaluation of Androgen Receptor (AR) Antagonist-Heat Shock Protein 90 (Hsp90) Inhibitor Conjugates for Targeted Therapy of Castration-Resistant Prostate Cancer.

Androgen deprivation in cases of castration-resistant prostate cancer (CRPC) leads to adverse effects, including loss of muscle and bone mass and gain of subcutaneous fat. The tumor-specific suppression of androgen receptor (AR) signaling, while not global, may reduce side effects. We present a class of small-molecular conjugates consisting of an AR antagonist linked to a heat shock protein 90 (Hsp90) inhibitor.
