SCORT-Cas13d Nanotherapy Precisely Targets the 'Undruggable' Transcription Factor HoxB13 in Metastatic Prostate Cancer In Vivo.

ABSTRACT: Metastatic cancer, the primary cause of cancer mortality, frequently exhibits heightened dependence on certain transcription factors (TFs), which serve as master regulators of oncogenic signaling yet are often untargetable by small molecules. Selective Cell in ORgan Targeting (SCORT) nanoparticles are developed for precise CRISPR/Cas13d mRNA and gRNA delivery to metastatic cancer cells in vivo, aiming to knock down the undruggable oncogenic TF HoxB13. In prostate cancer liver metastasis models driven by HoxB13, repeated systemic SCORT-Cas13d-gHoxB13 treatment significantly decreases HoxB13 expression, reduces metastasis, and extends mouse survival. Prolonged treatment shows no significant impact on major organ function, histology or immune markers. Mechanistically, SCORT-Cas13d-gHoxB13 tre
