Abstract
Deregulated apoptosis of germ cells may contribute to male infertility as well as malignant transformation. Survivin, an inhibitor of apoptosis (IAP), is overexpressed in all the most common human malignancies, but barely detectable in normal tissues. We used real-time polymerase chain reaction (PCR) to quantify survivin mRNA expression in normal testes (n = 22), testes with defective spermatogenesis (n = 26) and testicular germ cell tumours (TGCTs; n = 16). Survivin was expressed at high levels in normal testes. Testicular survivin levels in infertile patients were related inversely to the severity of spermatogenic failure (p < 0.001), with a lack of expression in most specimens with pre-meiotic spermatogenic arrest and in all those with germ cell aplasia. Lower levels of expression were observed in TGCTs than in normal testes. While survivin expression was detected in most TGCTs with undifferentiated components (12 of 13), it was absent in all mature teratomas (n = 3). These data show that survivin is expressed in normal and transformed germ cells. Its downregulation in spermatogenic disorders indicates that survivin may contribute to the normal balance between germ cell proliferation and apoptosis. In TGCTs, survivin expression appears to be lost with somatic differentiation. PMID: [16048634]

Abstract
Summary Apoptosis is a common phenomenon during spermatogenesis, and its dysregulation has been associated with male infertility. Survivin is an inhibitor of apoptosis protein that regulates apoptosis at cell division and is overexpressed in common human cancers. We investigated whether survivin mRNA expression is detectable in testicular biopsies from patients with infertility of varying aetiology. The aim of this study was to examine the testicular survivin expression in azoospermic men with normal spermatogenesis and in those with specific spermatogenic disorders. Survivin mRNA expression was detected by reverse transcriptase-polymerase chain reaction in histologically classified testicular biopsy specimens from 30 azoospermic men. Survivin was found to be expressed in normal spermatogenesis (n = 10), in post-meiotic spermatogenic arrest (n = 6), and in specimens showing a mixed picture of pre-meiotic maturation arrest with sparse islands of post-meiotic arrest (n = 2). In contrast, a lack of survivin expression was seen in specimens without haploid germ cells (pre-meiotic maturation arrest, n = 2) and in those with Sertoli-cell-only syndrome (SCOS, n = 10). These data indicate for the first time that survivin is expressed in human testis. Moreover, its expression seems to correlate with the stage of maturation arrest in patients presenting with spermatogenic disorders. Survivin mRNA expression was not found in SCOS specimens, possibly indicating germ-cell-specific expression in human testicular tissue. Thus, survivin is a potential molecular marker of spermatogenesis, whose expression is altered in specific spermatogenic disorders. PMID: [15139971]

Figures for illustrating the function of this protein/gene
Function
Multitasking protein that has dual roles in promotingcell proliferation and preventing apoptosis. Component of achromosome passage protein complex (CPC) which is essential forchromosome alignment and segregation during mitosis andcytokinesis. Acts as an important regulator of the localization ofthis complex; directs CPC movement to different locations from theinner centromere during prometaphase to midbody during cytokinesisand participates in the organization of the center spindle byassociating with polymerized microtubules. The complex with RANplays a role in mitotic spindle formation by serving as a physicalscaffold to help deliver the RAN effector molecule TPX2 tomicrotubules. May counteract a default induction of apoptosis inG2/M phase. The acetylated form represses STAT3 transactivation oftarget gene promoters. May play a role in neoplasia. Inhibitor ofCASP3 and CASP7. Isoform 2 and isoform 3 do not appear to playvital roles in mitosis. Isoform 3 shows a marked reduction in itsanti-apoptotic effects when compared with the displayed wild-typeisoform.

Subcellular Location
Cytoplasm. Nucleus. Chromosome. Chromosome,centromere. Cytoplasm, cytoskeleton, spindle. Chromosome,centromere, kinetochore. Midbody. Note=Localizes on chromosomearms and inner centromeres from prophase through metaphase.Localizes to kinetochores in metaphase, distributes to the midzonemicrotubules in anaphase and at telophase, localizes exclusivelyto the midbody. Colocalizes with AURKB at mitotic chromosomes.Acetylation at Lys-129 directs its localization to the nucleus byenhancing homodimerization and thereby inhibiting XPO1/CRM1-mediated nuclear export. 
Tissue Specificity
Expressed only in fetal kidney and liver, andto lesser extent, lung and brain. Abundantly expressed inadenocarcinoma (lung, pancreas, colon, breast, and prostate) andin high-grade lymphomas. Also expressed in various renal cellcarcinoma cell lines.
