Tekt5 mRNA levels increase substantially in spermiogenesis. (A): Quantitative RT-PCR of Tekt5 from mixed germ cell (MGC), pachytene spermatocytes (PS), round spermatids (RS), and condensing spermatids (CS). Results were normalized to mRNA corresponding to ribosomal protein S16. (B): Tekt5 mRNA was detected in testis and brain by RT-PCR. (C): RT-PCR analysis of Tekt5 mRNA from brain (Br), fat (Fa), heart (He), liver (Li), lung (Lu), oviduct (Ov), spleen (Sl), smooth muscle (Sm), and testis (Te). (D): Beta-actin was used as a loading control for various tissue samples.
