BackgroundOsteoporosis results in reduced bone mass and consequent bone fragility. Small interfering RNAs (siRNAs) can be used for therapeutic purposes, as molecular targets or as useful markers to test new therapies.Sources Of DataA systematic search of different databases to May 2023 was performed to define the role of siRNAs in osteoporosis therapy. Fourteen suitable studies were identified.Areas Of AgreementSiRNAs may be useful in studying metabolic processes in osteoporosis and identify possible therapeutic targets for novel drug therapies.Areas Of ControversyThe metabolic processes of osteoporosis are regulated by many genes and cytokines that can be targeted by siRNAs. However, it is not easy to predict whether the in vitro responses of the studied siRNAs and drugs are applicable in vivo.Growing PointsMetabolic processes can be affected by the effect of gene dysregulation mediated by siRNAs on various growth factors.Areas Timely For Developing ResearchDespite the predictability of pharmacological response of siRNA in vitro, similar responses cannot be expected in vivo.© The Author(s) 2023.
