The IC50 of Dox NPs and HP particles, esophageal squamous cell carcinoma, drug NPs was ~ 0.04-0.06 mg/mL and ~ 0.6-0.7 mg/mL, re- resistance spectively. Significant decrease occurred in cyclin D1 expression by Dox NPs and HP NPs (P < 0.05). Expo- Abstract sure of KYSE-30 cells to combined treatments includ- ing both Dox and HP extract significantly increased the Objectives: Esophageal squamous cell carcinoma level of cyclin D1 expression as compared to those with (ESCC) is considered as a deadly medical condition that individual treatments (P < 0.05). affects a growing number of people worldwide. Target- ed therapy of ESCC has been suggested recently and Conclusion: Dox NPs and HP NPs can successfully and required extensive research. With cyclin D1 as a thera- specifically target ESCC cells through downregulation peutic target, the present study aimed at evaluating the of cyclin D1.
