BIRC5 and neoplasm: Consequently, the expression of survivin protein decreases, eventually leading to tumour cell apoptosis.27 In this study, we modified miR‐214‐3p to complex with tFNAs (tFNAs‐miR‐214‐3p) and observed the ability of miR‐214‐3p to induce apoptosis of tumour cells (Figure 1).28 In addition, we validated the stability of tFNAs‐miR‐214‐3p in a variety of enzymatic environments by assaying serum stability.
