Identification of Novel Therapeutic Agent Candidates Through High Throughput Screening With Chemical Library Based on Molecular Subclassification in Canine Histiocytic Sarcoma Cell Lines

Veterinary and Comparative Oncology, Volume 24, Issue 3, Page 554-567, September 2026.
ABSTRACT Effective chemotherapy for canine histiocytic sarcoma (CHS) has yet to be established. In our previous study, CHS cell lines were subclassified into two groups based on their gene expression profiles: Group A and Group B. This study aimed to identify novel therapeutic agents that are effective against each CHS subgroup, and we performed high ...
