Expression of granzyme B (GZMB) mRNA and protein in the equine
endometrium. A: Real-time PCR analysis of GZMB mRNA in the equine
endometrium. Total RNA was extracted from equine endometrium in day 13 cyclic and in
days 13, 19, and 25 pregnant animals, lymph node and spleen. Bars represent means ±
SE. An asterisk indicates a significant difference (P<0.05) when compared with
the value from the cyclic endometrium. B: Western blot analysis of GZMB in the
cyclic and days 13, 19, and 25 pregnant endometrium, lymph node and spleen.
