Task: Answer Verification
Input (English): Question: Does paCaHa inhibit proliferation of human cancer cells in vitro?
Answer: PaCaHa showed dose dependent cytotoxic and antiproliferative effects on three distinct human cancer cell lines. The differential effect of PaCaHa on different cancer cell lines suggests that PaCaHa could have a potential antitumor effect on specific cancer types. These results support further comprehensive studies on PaCaHa and its derivatives.
Output (English): yes
