Retnla, an adipokine that regulates sterol synthase expression to control lipid metabolism27, was enriched in NIH3T3 cells after treatment with ciliary ligands (Fig. 1g, h and Supplemental Table 3) and was also enriched in Math1-Cre SmoM2c Hh-associated medulloblastomas compared to age-matched control cerebella17 (Fig. 4b and Supplementary Table 6).
