doi: 10.1007/s00262-022-03215-3
Figure Lengend Snippet: Lactate induces IGFBP6 expression which promotes M2-like phenotype polarization of microglia. Effect of lactate on IGFBP6 A mRNA expression levels, B protein expression and C production in microglia cells. Evaluation of relative mRNA expression levels of D ATP5F1A , E COX IV , F COX II , G CyTB , H ND4 . I Cytoplasm Mitotracker Intensity. Evaluation of relative mRNA expression levels of J Arg1, K CD 206 , L CD 163 and M TNF , analyzed by real-time PCR. The calculated value of 2 − ΔΔ Ct in untreated controls is 1. Immunocytochemistry analysis of N iNOS and O Arg1, following 72 h of IGFBP6 treatment. Data are expressed as mean ± SD of at least four independent experiments. (* P < 0.05; ** P < 0.005; *** P < 0.001; **** P < 0.0001). Scale bars in ( I, N and O ) 10 μm
Article Snippet: Then, the sections were incubated overnight at 4 °C with rabbit polyclonal anti-IGFBP6 antibody (Sigma, Milan, Italy), ready to use in PBS (Sigma, Milan, Italy) and MIB-1, a monoclonal antibody directed against the Ki-67 antigen (M7240; Dako Corporation, Glostrup, Denmark), diluted 1:75 in PBS (Sigma, Milan, Italy).
