(a) RNA-sequencing analysis of glycosylation and glycome-associated
genes of A375, A2058, and SkMel5 cells cultured under normoxia or hypoxia.
(b) HIF1α immunoblot for validation of hypoxia induction
in A375 and A2058 cells. Validation of GCNT2 downregulation and Gal-8, KLF4, and
NGFR upregulation under hypoxia in (c) A375 and (d)
A2058 by RT-qPCR. Flow cytometric analysis of Gal-8 expression on
(e) A375 and (f) A2058 cells grown under normoxia
or hypoxia. Flow cytometric analysis of i-linear poly-LacNAc expression using
OSK-28 antibody on (g) A375 and (h) A2058 cells grown
under normoxia or hypoxia. At least four biological replicates were performed.
***P < 0.001 **P < 0.01, and
*P < 0.05. Gal-8, galectin 8; GCNT2, β1,6
N-acetylglucosaminyltransferase 2; poly-LacNAc, poly-N-acetyllactosamine.
