Appendicular skeletal growth and bone mass acquisition are controlled by a variety of growth factors, hormones, and mechanical forces in a dynamic process called endochondral ossification. In long bones, chondrocytes in the growth plate proliferate and undergo hypertrophy to drive bone lengthening and mineralization. Pleckstrin homology (PH) domain and leucine rich repeat phosphatase 1 and 2 (Phlpp1 and Phlpp2) are serine/threonine protein phosphatases that regulate cell proliferation, survival, and maturation via Akt, PKC, Raf1, S6k, and other intracellular signaling cascades. Germline deletion of Phlpp1 suppresses bone lengthening in growth plate chondrocytes. Here, we demonstrate that Phlpp2 does not regulate endochondral ossification, and we define the molecular differences between Phlpp1 and Phlpp2 in chondrocytes. Phlpp2-/- mice were phenotypically indistinguishable from their wildtype (WT) littermates, with similar bone length, bone mass, and growth plate dynamics. Deletion of Phlpp2 had moderate effects on the chondrocyte transcriptome and proteome compared to WT cells. By contrast, Phlpp1/2-/- (double knockout) mice resembled Phlpp1-/- mice phenotypically and molecularly, as the chondrocyte phospho-proteomes of Phlpp1-/- and Phlpp1/2-/- chondrocytes had similarities and were significantly different from WT and Phlpp2-/- chondrocyte phospho-proteomes. Data integration via multiparametric analysis showed that the transcriptome explained less variation in the data as a result of Phlpp1 or Phlpp2 deletion than proteome or phospho-proteome. Alterations in cell proliferation, collagen fibril organization, and Pdpk1 and Pak1/2 signaling pathways were identified in chondrocytes lacking Phlpp1, while cell cycle processes and Akt1 and Aurka signaling pathways were altered in chondrocytes lacking Phlpp2. These data demonstrate that Phlpp1, and to a lesser extent Phlpp2, regulate multiple and complex signaling cascades across the chondrocyte transcriptome, proteome, and phospho-proteome and that multi-omic data integration can reveal novel putative kinase targets that regulate endochondral ossification.
