Figure Lengend Snippet: EMMPRIN promotes angiogenesis in the lung PMN. Mice were injected with the different tumor cells and treatments as described in the legend of Figure 1 . (A) Representative images of the endothelial cell marker CD31 staining in the lungs, and (C) their quantitation (n=9 for the D2A1-WT group, n=8 for the D2A1-KD group, n=7 for the healthy group, n=7 for the D2A1-WT + m161-pAb group, n=9 for the Healthy + rec. EMMRPIN group). Bar size is 100 μm. (B) Representative images of bEND3 endothelial cell migration length after their incubation for 18 h with serum-starvation media containing 5µg of lung lysates from the different experimental groups. (D) Quantitation of the migration length (n=14 for the D2A1-WT group, n=10 for the D2A1-KD group, n=8 for the healthy group, n=9 for the D2A1-WT + m161-pAb group, n=7 for the Healthy + rec. EMMRPIN group). Bar size is 150 μm. Data are presented as mean ± SEM. Three groups were analyzed using one-way ANOVA followed by Bonferroni’s post-hoc test, and two groups were compared using the non-parametric two-tailed Mann-Whitney t test. The increased CD31 staining of endothelial cells in the mice implanted with the D2A1-WT cells and their longer migration distance suggests that they proliferate and migrate, two properties necessary for angiogenesis, more than the endothelial cells in healthy mice or mice implanted with the D2A1-KD cells. The importance of EMMPRIN to this process is exemplified by the results from the addition of h161-pAb or the injection of recombinant EMMPRIN.

Figure Lengend Snippet: Tracing of glycerophosphocholine metabolism. (A) Cellular acylation of lyso-phosphatidylcholine (LPC) by fatty acids (FA, or other acyl donors) yields phosphatidylcholine (PC) and upon de-acylation LPC is re-produced. This Lands cycle allows for side-chain exchange. (B) A library of synthetic head group-labeled (magenta) alkyne tracers featuring saturated (SaFA), mono-unsaturated (MUFA), or poly-unsaturated (PUFA) fatty acid side chains at the sn - 1 position were synthesized. The N-propargyl- sn 2 -lysophosphatidylcholine (LpPC) tracer family includes members with ω−6 (orange) and ω−3 (red) PUFA side chains. Also an ether derivative (LpPCO) containing an sn 1 -O-alkyl side chain (green) was synthesized. (C) bEND3 cells were incubated for 24 h with 50 μM LpPC containing the indicated side chain. Total lipids from cells were isolated, click-reacted and analyzed by TLC. Fluorescent bands were identified by co-migrating standards (closed arrowheads). Cellular pPC metabolites were detected as multiple bands. The double band migrating between LpPC and pPC putatively represents pSM (open arrowhead). ori, origin of application.

doi: 10.1016/j.jlr.2025.100773

Figure Lengend Snippet: MS analysis of pPC metabolism in bEND3 cells over time. Cells were incubated with one of four LpPC tracers (50 μM) for various times. Total cellular lipids and internal standards were co-isolated and click-reacted before multiplexed MS analysis. All labeled pPC species were quantified (see supplemental Tables S1–S4 ) and the total cellular pPC content per 100,000 cells is plotted over time (A). Error bars smaller than symbol size are omitted. Cells incubated with (B) LpPC 16:0, (C) LpPC 18:2, (D) LpPC 20:4, or (E) LpPC 22:6 showed distinct distributions of labeled pPC species at each time point. Upon 24 h (magenta bars) of constant tracer supply and ongoing cellular lipid remodeling the labeled lipidome differed substantially from earlier time points. The species distribution of unlabeled control samples (green bars) is also shown. Labeled pPC species are presented as the molar fraction (mol%) of all labeled pPC species. N = 3.

Figure Lengend Snippet: Analysis of LPC acylation and PC side chain remodeling in bEND cells. (A) Experimental scheme: For 30 min bEND3 cells were pulse-incubated with 50 μM LpPC containing the indicated side chain and 50 μM of the homologous isotope-labeled FA (red) to generated isotope-labeled symmetric pPC metabolites. Symmetric pPC lacking an isotope label was produced if the unlabeled homologous FA (magenta) served as acylation partner. Cells were chased in the presence of isotope-labeled oleate (green) for the indicated time during which side chain replacement yielded labeled asymmetric pPC. (B–E) The amount of selected pPC species is presented over time as detected by MS in lipid extracts from cells incubated with (B) LpPC 16:0, (C) LpPC 18:2, (D) LpPC 20:4 and (E) LpPC 22:6. The isotope-labeled symmetric pPC (red) and the symmetric pPC lacking an isotope label (magenta) were produced first during the pulse. Generated upon side chain remodeling, the pPC species carrying the side chain of the respective input LpPC as well as the 13C-oleate added during chase is highlighted in green. The sum of all pPC species labeled by 13C-oleate during the chase is shown in cyan. N = 3.
