These effects corroborate with the Aurora A kinase inhibition suggesting that TACC3 expression is essential for suitable meiotic spindle development

Throughout mitotic Mobile division, it has been shown that Aurora A-activated TACC proteins stabilize the centrosomal microtubules [9,21]. We detected TACC3 mRNA expression in maturing bovine oocytes and early cleavage stage embryos up to the eight mobile stage, after which Fig three. TACC3 co-localization with tubulin. TACC3 co-localizes with tubulin in the spindle at 1227923-29-6 metaphase I, is not expressed at anaphase and reappearance at telophase. TACC3 is not present in the polar entire body.

GV, MI, MII, 2 Mobile, 4 Cell, eight Mobile, correspond to germinal vesicle, metaphase I, metaphase II, two-cell web site embryo, 4-cell embryo, and 8-cell embryo, respectively. Different letters higher than bars (a,b) indicate values that vary significantly (p
