Supplementary Material - Background
Development of chemotherapeutics for the treatment of advanced hepatocellular carcinoma (HCC) has been lagging. Screening of candidate therapeutic agents by using patient-derived preclinical models may facilitate drug discovery for HCC patients.
Methods
Four primary cultured HCC cells from surgically resected tumor tissues and six HCC cell lines were used for high-throughput screening of 252 drugs from the Prestwick Chemical Library. The efficacy and mechanisms of action of the candidate anti-cancer drug were analyzed via cell viability, cell cycle assays, and western blotting.
Results
Guanabenz acetate, which has been used as an antihypertensive drug, was screened as a candidate anti-cancer agent for HCC through a drug sensitivity assay by using the primary cultured HCC cells and HCC cell lines. Guanabenz acetate reduced HCC cell viability through apoptosis and autophagy. This occurred via inhibition of growth arrest and DNA damage-inducible protein 34, increased phosphorylation of eukaryotic initiation factor 2α, increased activating transcription factor 4, and cell cycle arrest.
Conclusions
Guanabenz acetate induces endoplasmic reticulum stress–related cell death in HCC and may be repositioned as an anti-cancer therapeutic agent for HCC patients. -

Abstract
- A three year old girl with a left renal teratoid Wilms tumor is reported. The tumor was located both inside and outside the kidney parenchyme, to form a well encapsulated mass containing two lobulated solid and cystic masses. The tumor consists predominantly of otherwise typical Wilms tumor irregularly mixed with teratoid tissue elements such as intestinal tract, mucous glands with argentaffin cells, goblet cells and transitional epithelium. These heterologous elements were regarded as diverse epithelial differentiation of totipotent cells in certain nephrogenetic period, and this tumor was considered to be hest called "teratoid Wilms tumor".
