Predicted secondary structures and free energies of siRNA duplexes targeting GPR10 mRNA. Ten siRNA candidates were evaluated for thermodynamic stability using RNAstructure’s DuplexFold algorithm. The secondary structures shown correspond to siRNA3, siRNA6, siRNA8, siRNA10, siRNA12, siRNA13, siRNA14, siRNA17, siRNA18, and siRNA23. Calculated minimum free energy (ΔG) values range from − 38.7 kcal/mol (siRNA6) to −31.4 kcal/mol (siRNA23), with more negative values indicating greater duplex stability.
