Expression of fz5, wnt5a, and
β-actin in RA tissue samples and adult tissues by Northern analysis.
A–C show the expression of β-actin,
fz5, and wnt5a in RA tissue specimens.
D–F show the expression of the same genes in 12 adult
tissues that are peripheral blood leukocyte, lung, placenta, small
intestine, liver, kidney, spleen, thymus, colon, skeletal muscle,
heart, and brain (lanes 1–12, respectively, in D–F).
(A) Northern blot showing 2.3-kb β-actin-specific band
in three RA tissue specimens; (B) 5-kb
fz5-specific band in three RA tissue specimens;
(C) lanes 1–3, 5-kb wnt5a-specific band
in three RA specimens; lane 4, wnt5a-specific band in
fetal fibroblast as a positive control. (D) Northern
blot showing 2.3-kb β-actin-specific band in 12 different adult
tissue specimens; (E) 5-kb fz5-specific
band in the 12 adult tissue Northern blot; (F) result of
wnt5a probe hybridization by using the same Northern
blot. Specific activity of the probes used for hybridization and RNA
concentrations of the tissue samples was the same for each analysis.
The adult multiple tissue Northern blot was stripped and reprobed
during the course of the experiments, and β-actin hybridization was
performed last of all.
