Figure 5. UCP2 decreases mast cell histidine decarboxylase expression.
(A) Real-time quantitative PCR of histidine decarboxylase mRNA transcripts from wild-type and Ucp2−/− BMMCs normalized to 18s rRNA. *P < 0.05. Data are the mean ± SD of three experiments. (B) Immunoblot of lysate from wild-type and Ucp2−/− BMMCs with anti-HDC antibody. Immunoblot is representative of three independent experiments with similar results. (C) Superoxide production of wild-type and Ucp2−/− BMMCs measured by dihydroethidium using flow cytometry. Histogram is representative of three experiments with similar results. (D) Total histamine content of BMMCs after 5 day treatment with TBAP (20–40 μM). *P < 0.05. Data are the mean ± SD (n=3).
