mTORC1 regulates PTHrP to coordinate chondrocyte growth, proliferation and differentiation

mTORC1 is crucial for chondrocyte proliferation and bone growth, but the downstream signalling is not clear. Here, the authors use rapamycin and chondrocyte-specific Tsc1 knockout mice to show that S6K1 can cause nuclear accumulation of Gli2, thus driving PTHrP expression and preventing terminal dif...

Sumario:mTORC1 is crucial for chondrocyte proliferation and bone growth, but the downstream signalling is not clear. Here, the authors use rapamycin and chondrocyte-specific Tsc1 knockout mice to show that S6K1 can cause nuclear accumulation of Gli2, thus driving PTHrP expression and preventing terminal differentiation of prehypertrophic chondrocytes.
