چکیده انگلیسی
Cancer/testis antigens (CTAs) are characterized by their restricted expression pattern. In normal individuals their expression is largely restricted to the testis. In the case of cancer patients, CTA expression has also been frequently observed in the tumoral cells. CTAs are considered to be promising targets for immunotherapy. However, almost nothing is known about the properties defined by the vast majority of CTAs. Here, we have investigated the expression pattern and localization of the CTA CAGE-1 during mouse spermatogenesis. We show that protein CAGE-1 is 849 amino acids long. Analysis of the first spermatogenic wave of pubertal mice by RT-PCR and immunoblotting showed that CAGE-1 is predominantly expressed during postmeiotic stages. CAGE-1 localizes to the acrosomal matrix and acrosomal granule, as demonstrated by immunocytochemistry at the light and electron microscopic level. Taken together, our results allowed to define protein CAGE-1 as a novel component of the acrosome of mammalian spermatids and spermatozoa.
