Expression of high mobility group protein A in male mouse testicular cell lines / 中华男科学杂志

<p><b>OBJECTIVE</b>To detect the expression of high mobility group protein A (HMGA) in male mouse testicular cell lines TM4, GC-1spg and GC-2spd(ts), and to pave the theoretical ground for further investigation of the action mechanism of the HMGA gene in male mouse spermatogenesis.</p><p><b>METHODS</b>We detected the expressions of HMGA1 and HMGA2 by RT-PCR and Western blot in the male mouse testicular cell lines TM4, GC-1spg and GC-2spd(ts).</p><p><b>RESULTS</b>HMGA1 and HMGA2 were expressed in the male mouse testicular cell lines TM4, GC-1spg and GC-2spd(ts) at both mRNA and protein levels. Western blot and RT-PCR methods showed similar results.</p><p><b>CONCLUSION</b>The expression of HMGA may be involved in the cell division and proliferation of TM4, GC-1spg and GC-2spd(ts) and play an important role in spermatogenesis of male mice.</p>
