Layer‐by‐layer assembled PLGA nanoparticles carrying miR‐34a cargo inhibit the proliferation and cell cycle progression of triple‐negative breast cancer cells

Triple‐negative breast cancer (TNBC) accounts for 15–25% of diagnosed breast cancers, and its lack of a clinically defined therapeutic target has caused patients to suffer from earlier relapse and higher mortality rates than patients with other breast cancer subtypes. MicroRNAs (miRNAs) are small non‐coding RNAs that regulate the expression of multiple genes through RNA interference to maintain normal tissue function. The tumor suppressor...
