In transgenic mice that communicate EML4-ALK in lung epithelial cells specifically, hundreds of adenocarcinoma nodules develop in both lungs after birth soon, and oral administration of a particular inhibitor of ALK tyrosine kinase activity quickly eradicates such nodules from the lungs.
In macaques, TEX11 signal was detected in zygotene spermatocytes and spermatids . Likewise, in humans, TEX11 was detected in late-pachytene spermatocytes and in circular and elongated spermatids . Two specific patterns of TEX11 expression were seen in these specimens. In testicular biopsy specimens that showed blended testicular atrophy, TEX11 staining was present in spermatocytes and in round and elongated spermatids in the majority of tubules . However, in biopsy specimens obtained from patients with total meiotic arrest, spermatids were not seen, and TEX11 expression was not detected generally in most seminiferous tubules; just a few tubules with late spermatocytes and round spermatids got TEX11 expression . Discussion In most metazoans, meiosis includes a function in generating biologic diversity and supporting species survival.
