Drug resistance is an important factor for prostate cancer (PCa) to progress into refractory PCa, and abnormal lipid metabolism usually occurs in which presents great challenges PCa therapy. Here, a cluster of differentiation 36 (CD36) inhibitor sulfosuccinimidyl oleate sodium (CD36i) stearoyl-CoA desaturase 1 (SCD1) siRNA (siSCD1) are selected inhibit uptake synthesis respectively. To this end, multiresponsive drug delivery nanosystem, HA@CD36i-TR@siSCD1 designed. The hyaluronic acid (HA) gel "shell" HA-TR nanosystem can release drugs response the acidic tumor microenvironment hyaluronidase, targeting (TR) cationic micellar "core" glutathione. This beneficial exogenous inhibition by CD36i endogenous siSCD1. established has good ability penetration ability, that synergistic effects, significantly restrain growth, invasion, metastasis PCa. Moreover, under high-fat conditions, tumors more sensitive treatment, almost no accumulation droplets observed HA@CD36i-TR@siSCD1-treated tumors, with enhanced antitumor immunity. Hence, study provides new treatment option patients, especially those diet.
