Fig. 4. C1s inhibits binding of IT4var20 IE to EPCR and IT4var13 IE binding to <t>CD36</t> but not ICAM-1. (A) Binding of IT4var20 IEs to EPCR in the absence or presence of C1s (100 μg/mL). Recombinant EPCR (rEPCR) was included as a control and indicator of how well C1s treatment abrogated IT4var20 binding to EPCR. (B) Binding of IT4var13 IEs to CD36 or ICAM-1 in the absence or presence of C1s (100 μg/mL). In both binding assays, bovine serum albumin (BSA) was included as a negative control. The mean and SEM are shown, and each data point is from an independent experiment. For statistical testing, all mean values were log-transformed, and a two-tailed unpaired t test was conducted to compare experimental groups to the positive control (EPCR only). (C) Var gene transcript levels relative to the housekeeping control gene, seryl-t-transferase, confirming the major var types being expressed as IT4var20 and IT4var13. *P < 0.05; **P < 0.01; ns, not significant.

Fig. 6. Analysis of C1s-treated recombinant PfEMP1. (A) SDS/PAGE gel showing two representative PfEMP1 CIDR domains (EPCR-binding IT4var19 CIDRα1 and CD36-binding CIDRα3) and two EPCR-binding head-structure domain complexes (PFD1235w [NTSA-DBLα1-CIDRα1] and IT4var20 [NTSA-DBLα1-CIDRα1]) before and after treatment with 50 nM C1s at 1:1 molar ratio for 1 h at 37 °C. No proteolysis was seen. (B) ELISA data showing the effect of 50 nM C1s pretreatment on binding of recombinant PfEMP1 proteins to coated EPCR, CD36, or ICAM-1 (filled boxes) versus EPCR binding to coated recombinant PfEMP1 (hashed boxes). Whereas C1s treatment reduced binding activity of full-length PfEMP1 ectodomains, recombinant PfEMP1 head structure domains are insensitive to C1s treatment, indicating that C1s cleavage sites are located in the interdomain regions, consistent with MS analysis. As a control, C1s treatment of EPCR did not affect its binding to full-length PfEMP1 ectodomains (hashed boxes).

Primary-melanoma-secreted EVs in lymphatic fluid enter the SLN via afferent lymphatic vessels. The SLN components, including macrophages and endothelial cells, receive these EVs to upregulate CD36, possibly through CD36 cargoes (mRNA and protein). The upregulation of CD36 in the targeted cells can mediate the immunosuppression mechanism to promote the tumor-promoting niche in the SLN.

PA treatment promoted metastasis and induced CD36 expression through activating the HBP. (A) GFAT and OGT mRNA levels in MKN-45 or SGC 7901 cells were assessed by real-time PCR after treatment with the indicated concentration of PA or control solvent for 3 h. The values shown are expressed as the means ± SD of three independent experiments. (B) GFAT, OGT and CD36 levels in MKN-45 or SGC 7901 cells were assessed by western blotting after treatment with the indicated concentration of PA or control solvent for 3 h. (C) The levels of O-GlcNAcylation in MKN-45 or SGC 7901 cells were assessed by western blotting after treatment with 10 μM TMG or isometric DMSO for 24 h. β-actin was used as a loading control. (D) Transwell migration and invasion assay of MKN-45 and SGC 7901 cells after10 μM TMG or isometric DMSO treatment for 24 h. (E) Indicated cells were injected into nude mice (n = 10 for each group) via the tail vein and mice were fed with HFD. Animals were sacrificed at 6 weeks after the injections. Representative HE staining of the metastatic nodes in mouse lungs from each group. (F) Left: The histogram shows the proportion of mice with lung metastasis in each group. “Met” is short for “metastasis,” and “Met-free” represents “metastasis-free.” Right: Mann Whitney test was used to evaluate the number of metastatic nodes in the lungs of each group. * represents Mann Whitney test p < 0.05.
