15515157 Decreases in the CRABP1 (cellular retinoic acid binding protein 1) and TFF3 (trefoil factor 3) expression levels identified these as candidate molecular biomarkers for papillary thyroid carcinoma.
15281009 increased CYP26-mediated catabolism of retinoic by CRABP-I transfection might decrease the amount of retinoic acid that is accessible to the nuclear receptors
14713576 CRABP I plays an important role not only in mediating the retinoid effects, but also in modulating the radiation sensitivity of tumour cells after combined retinoic acid radiation treatment.
14605320 CSF of Moyamoya Disease [MMD] patients reveals high CRABP-I expression suggesting that the elevation of CRABP-I in CSF may be a candidate for pathogenesis of MMD
