The glial cell line-derived neurotrophic factor (GDNF) has multiple functions that promote cell survival, proliferation and migration in different cell types. The experimental over-expression of GDNF in mouse testis leads to infertility and promotes seminomatous germ cell tumours in older animals,

The human endogenous retrovirus K10 (HERV-K10) has been identified in the human genome by its homology to retroviruses of other vertebrates (M. Ono, T. Yasunaga, T. Miyata, and H. Ushikubo, J. Virol. 60:589-598, 1986). Using PCR amplification, DNA cloning, sequencing, and procaryotic expression, we

Protease activated receptor-2 (PAR-2) is the receptor for the prototype mast cell product tryptase. PAR-2 expression by cells of the human germinal epithelium was reported, but the exact cellular sites of testicular expression remained unknown. That became of interest, because mast cells, expressing

OBJECTIVE Testisin, a serine protease abundantly expressed only in normal testes, is thought to be a tumor suppressor gene silenced by aberrant methylation in testicular germ cell tumors (TGCT). This study aimed at identifying the CpG sites relevant for testisin gene silencing when methylated and

Intratubular malignant germ cells (ITMGC), as assessed by clinicopathologic or cytogenetic studies, are regarded as a preinvasive lesion of all human testicular germ cell tumors with the exception of yolk sac tumors (in infants) and spermatocytic seminomas. To characterize specific surface molecules

BACKGROUND Nucleotide-binding domain and leucine-rich repeat-containing family, pyrin domain-containing 7 (NLRP7) (pyrin-containing apoptotic protease activating factor-1-like protein 3; PYPAF3, NACHT domain-, leucine-rich repeat, and pyrin domain-containing 7; NALP7) has been thought to contribute

Apoptotic protease activating factor-1 (APAF-1) is a key regulator gene of apoptosis, located downstream from p53. Loss of APAF-1 expression is associated with chemorefractory malignant melanoma and neuronal cell differentiation. In order to make clear the function of APAF-1 in the carcinogenesis of

OBJECTIVE To present our recent observations obtained from the continuing characterization of the TSP50 gene pertaining to its evolutionary importance and behavior in human testicular germ cell tumors. Previous studies have reported that expression of the human TSP50 gene is testes specific. Its
