Article Title: Identification of C -mannosylation in a receptor tyrosine kinase AXL

doi: 10.1093/glycob/cwae096

Figure Lengend Snippet: DPY19 family proteins are not C -mannosyltransferases of AXL. (A) Establishment of AXL-ECD and DPY19 family-co-expressing S2 cells. S2 cells were transfected with pMT-PURO-AXL-ECD and pIZ-DPY19L1, L2, L3, or L4. mRNA expression levels of DPY19 family were measured by RT-PCR. Mock S2 cells were co-transfected with pMT-PURO-AXL-ECD and pIZ/V5-his empty vector. (B) C -mannosylation of AXL is not catalyzed by DPY19 family proteins. Recombinant AXL-ECD was purified from conditioned media of DPY19 family-expressing S2 cells. These samples were analyzed by LC–MS/MS. Only unmodified 309 VACTSSQGPSSWTHWLPVETPE 330 peptides were detected in samples from mock and DPY19L1-, L2-, L3-, and L4-expressing cells as m / z = 1235.6. (C and D) mRNA expression level of DPY19 family in MDA-MB-231 cells. cDNA of HT1080 and NEC8 cells were used as a positive control of DPY19L1, L3, and L4 (HT1080, C), and DPY19L2 (NEC8, D).

Article Title: Clinicopathological Significance and Antitumor Effect of MPHOSPH1 in Testicular Germ Cell Tumor

doi: 10.7150/jca.25279

Figure Lengend Snippet: The efficacy of MPHOSPH1 knockdown using small-interfering RNA (siRNA). A . Protein was extracted from the cell lines at 24 h and 48 h post-transfection. Knockdown of MPHOSPH1 was confirmed by Western blotting ( A ). MPHOSPH1 knockdown significantly reduced cell migration ( B ) and cell invasion ( C ) in both NEC8 and NEC14 ( p <0.001 for both). MPHOSPH1 knockdown also significantly inhibited cell proliferation ( D ) and colony formation ( E ) in both of the cell lines ( p <0.001 for both).

Article Snippet: The human embryonal carcinoma cell lines NEC8 and NEC14 were purchased from the Riken Bioresource Center (Tsukuba, Japan) and cultured in RPMI-1640 medium with 10% fetal bovine serum (FBS).
