Hormone sensitive lipase ablation promotes bone regeneration.

Biochim Biophys Acta Mol Basis Dis 2022 May 23:166449. Epub 2022 May 23.

Division of Endocrinology, Gerontology, and Metabolism, Stanford University, Stanford, CA, USA; Veterans Affairs Palo Alto Health Care System, Palo Alto, CA, USA; Stanford Diabetes Research Center, Stanford, CA, USA. Electronic address:

There is an inverse relationship between the differentiation of mesenchymal stem cells (MSCs) along either an adipocyte or osteoblast lineage, with lineage differentiation known to be mediated by transcription factors PPARγ and Runx2, respectively. Endogenous ligands for PPARγ are generated during the hydrolysis of triacylglycerols to fatty acids through the actions of lipases such as hormone sensitive lipase (HSL). To examine whether reduced production of endogenous PPARγ ligands would influence bone regeneration, we examined the effects of HSL knockout on fracture repair in mice using a tibial mono-cortical defect as a model.
