A Detection of phosphorylated Smad2 (pSmad2) and total Smad2 (Smad2) in cell lysates from wild-type and tmem165-knockout mouse ATDC5 cells (n = 3). B Fold changes of serpine expression in tmem165-knockout cells normalized to wild-type mouse ATDC5 cells. C Fold changes of TGF-β reporter activity in tmem165-knockout cells normalized to wild-type mouse ATDC5. D Detection of phosphorylated Smad2 (pSmad2) and total Smad2 in cell lysates from control and TMEM165-deficient CDG patient fibroblast cells (n = 3). E Fold changes of serpine expression in TMEM165-deficient fibroblasts normalized to normal fibroblast cells. F Detection of p-Smad2 in cell lysates from wild-type and tmem165-knockout mouse ATDC5 cells and (G) from normal and TMEM165-deficient CDG patient fibroblast cells treated or not with TGFβ1 (1 ng/ml) for 1 hour (n = 3). H Fold changes of TGFβR1 and TGFβR2 expression in tmem165-knockout mouse ATDC5 cells normalized to wild-type mouse ATDC5 cells. I Detection of TGFβR2 in cell lysates from wild-type and tmem165-mutant mouse ATDC5 (n = 3). J Fold changes of TGFβR1 and TGFβR2 expression in TMEM165-deficient fibroblasts from CDG patient normalized to normal fibroblast cells. K Detection of TGFβR2 in cell lysates from normal fibroblasts and TMEM165-deficient CDG patient fibroblast cells (n = 3). L Fold changes of asporin expression in tmem165-knockout cells normalized to wild-type mouse ATDC5 cells and in TMEM165-deficient fibroblast cells normalized to normal fibroblast cells. M Detection of asporin in conditioned medium of wild-type and tmem165-knockout mouse ATDC5 cells and of normal fibroblasts and TMEM165-deficient CDG patient fibrobast cells. β-actin was used as loading control (n = 3). qPCR values were normalized for the housekeeping gene ribosomal protein S29 and are expressed as the relative expression compared with control. Data are expressed as mean ± S.D. Statistical analysis was performed with an unpaired Student’s t test (n = 3; *p < 0.05; **p < 0.01). Representative images from three independent experiments are shown.
