Figure Lengend Snippet: MMP12 silencing inhibited M2 macrophage polarization. THP-1 cells were differentiated into M0 macrophages (THP-1 M0) by treatment with 100 ng/mL PMA for 24 h. (A) Flow cytometry was used to quantify the number of CD68-positive cells. Subsequently, KYSE150 cells were co-cultured with the THP-1-derived macrophages using a Transwell system. (B) The mRNA levels of IL-10, Arg-1, and TGF-β were detected by qRT-PCR. (C) Flow cytometry was used to quantify the number of CD206-positive macrophages. (D) Cell migration analysis by transwell migration assay. ∗ P < 0.05, ∗∗ P < 0.01 and ∗∗∗ P < 0.001.

Article Snippet: Additionally, to determine the proportion of CD206-positive macrophages, single-cell suspensions of these cells were incubated with a FITC-conjugated anti-CD206 antibody (E-AB-F1161E, Elabscience).

Figure Lengend Snippet: WTAP silencing inhibited M2 macrophage polarization by regulating MMP12. THP-1 cells were differentiated into M0 macrophages (THP-1 M0) by treatment with 100 ng/mL PMA for 24 h. KYSE150 cells were transfected with si-WTAP, MMP12 overexpression plasmid, or the matched control (si-NC and oe-NC). Subsequently, these KYSE150 cells were co-cultured with the THP-1-derived macrophages using a Transwell system. (A) The mRNA levels of IL-10, Arg-1, and TGF-β were detected by qRT-PCR. (B) Flow cytometry was used to quantify the number of CD206-positive macrophages. (C) Cell migration analysis by transwell migration assay. ∗ P < 0.05, ∗∗ P < 0.01 and ∗∗∗ P < 0.001.

Figure Lengend Snippet: Tert KO induces lipid‐associated macrophages (LAMs). Starch‐induced i.p. macrophages from 2‐year‐old female mice were analyzed. (a) Upon adherence in primary culture, IF with antibodies against CD80 (M1‐macrophage) and CD206 (M2‐polarization) markers reveals a lower frequency of CD206 + macrophages in KO mice. (b) Data quantification from multiple fields of view in (a), indicating macrophage polarization shift toward the M1 phenotype. (c) Upon LPS (100 ng/mL, 4 h) treatment in primary culture, q‐RT‐PCR (normalized to 18S RNA) demonstrates higher expression of genes coding for inflammation markers IL1 and IL6 in KO macrophages. (d) Macrophages were induced to convert into foam cells by oxLDL (0.025 mg/mL) treatment for 24 h. Note increased uptake of red‐fluorescent C 12 ‐BODIPY (0.3 μM, 5 min) by mG+ KO cells (yellow arrows) compared to mG+ WT cells (green arrows) in primary culture. (e) q‐RT‐PCR (normalized to 18S RNA) demonstrates lower expression of genes coding for lipid efflux effectors APOE, LDLR, ABCA1, ABCG1, and higher expression of genes coding for lipid transporters CD36 and FABP5 in KO oxLDL‐treated macrophages. (f) OxLDL‐treated macrophages stained with Oil Red O: Note larger lipid droplets (arrows) in KO cells. For all data, mean+/− SEM (error bars). * p < 0.05, ** p < 0.01, *** p < 0.001 (two‐sided Student's t ‐test). Scale bar: 50 μm.
