H19 and cancer: RNA interference (RNAi) technology based on shRNAs, small interfering RNAs (siRNAs), antisense oligonucleotides (ASOs), and clustered regulatory interspaced short palindromic repeats/CRISPR-associated protein 9 (CRISPR‒Cas9) are accessible genetic tools that can be used to target H19 to inhibit cancer progression and sensitize the therapeutic response to chemotherapy, thus improving clinical outcomes [127].
