Recombinant Human Deleted in azoospermia protein 1 (DAZ1)

1. There was an increased frequency of DAZ microdeletion in blood samples from oligozoospermic and near azoospermic patients. A high frequency of DAZ microdeletion was observed in the sperm of patients with no DAZ microdeletion in their leukocytes compared to control. The results might be indicative of DAZ microdeletion induction during spermatogenesis. PMID: 28521575
2. We investigated partial deletion of AZFc region and DAZ copy number in a population of Iranian infertile men and normozoospermic controls. PMID: 27739146
3. Susceptibility of gr/gr rearrangements to azoospermia or oligozoospermia is dependent on DAZ and CDY1 gene copy deletions. PMID: 26149076
4. Overexpression of DAZ1 is associated with breast tumors. PMID: 25994570
5. Studies indicate that partial RNA-binding proteins DAZ1/2 deletion was associated wih male infertility, but partial RNA-binding proteins DAZ3/4 deletion was not associated with male infertility. PMID: 26232607
6. We did not found any statistically significant genetic association between DAZ alleles and idiopathic male infertility PMID: 25916124
7. genetic association study in Chinese population: Data suggest that combined patterns of copy number abnormality in DAZ1 (deleted in azoospermia 1) and/or BPY2 (basic charge Y-linked protein 2) are associated with spermatogenic impairment/azoospermia. PMID: 24935076
8. There appears to be an asociation of DAZ1/DAZ2 deletion with spermatogenic impairment and male infertility in the South Chinese population. PMID: 23512232
9. Report the prevalence of variations in the AZFc region of the human Y chromosome in infertile men. PMID: 23422238
10. genetic association studies in Han population in China: Data suggest that AZF1/DAZ1 duplications underlie genetic predisposition of Y-chromosome haplogroup K* to spermatogenic impairment (azoospermia/oligospermia) in the population studied. PMID: 23696539
11. The methylation patterns of CpG island (CGI) in the DAZ gene promoter region were different between somatic cells and spermatic cells PMID: 20170395
12. role in male infertility - review PMID: 11688365
13. altered transcription in azoospermia PMID: 11869379
14. DAZ gene copy number in severely idiopathic infertile men. Gene deletion of two copies of DAZ (DAZI and 2) was the cause of spermatogenic damage. PMID: 11883873
15. Sertoli cell function is not damaged in patients with AZFc-DAZ deletions and that the strong reduction of germ cells does not affect the FSH-inhibin B feedback loop. PMID: 12039700
16. DAZ/DAZL protein can form a stable complex with human PUM2. PMID: 12511597
17. Loss of only some copies of DAZ is sufficient to lead to severe male infertility, but it is not a frequent finding in cryptorchid men. PMID: 15066457
18. Role in spermatogenesis. Decreased DAZ proteins in spermatogenic failure may be due to germ cell loss. Transcription of BOULE, DAZL, and DAZ not altered in degrees of spermatogenic failure. No increase of DAZL or BOULE found in DAZ deletion. PMID: 15066460
19. The deleted in azoospermia (DAZ) are believed to have important function in sperm production, since DAZ is frequently deleted in azoospermic and severy oligozoospermic men. PMID: 15253135
20. The frequency of partial copy deletion of DAZ gene in Chinese idiopathic azoospermia or severe oligozoospermia patients is much higher, suggesting that the deletion of DAZ1/DAZ2 may be one of the important factors of spermatogenesis damage. PMID: 15476166
21. DAZ activates translationally silent mRNAs during germ cell development through the direct recruitment of polyA-binding proteins. PMID: 16001084
22. Additional polymorphisms identified within the DAZ repeat regions of the DAZ genes indicate that sister chromatid exchange plays a significant role in the genesis of deletions, duplications, and polymorphisms of the Y chromosome. PMID: 16085382
23. DAZ genes are prone to deletions and duplications. Partial DAZ gene deletions are associated with oligozoospermia. PMID: 16275261
24. An association between DAZ haplotypes and Y chromosome haplogroups was found, and data show that the DAZ gene is not under selective constraints and its evolution depends only on the mutation rate. PMID: 16777954
25. The results showed that DAZ gene activity seems to correspond to the proliferative activity of stem cells of germinal epithelium. PMID: 16805138
26. DAZ cannot bind simultaneously to DAZAP1 and poly(A)-binding protein (PABP), and suggest that the phosphorylation-induced dissociation of DAZ and DAZAP1 may allow the former to stimulate translation by interacting with PABP. PMID: 16848763
27. complete DAZ deletion is a frequent genetic cause of severe oligozoospermia, and DAZ1/DAZ2 deletion is a high risk factor for the disease PMID: 16963411
28. AZFc subdeletions do not seem to cause severe impairment of spermatogenesis in Chilean men. PMID: 17416365
29. Quantitative real-time PCR assays of this protein gave positive predictive values of 78 per cent for the recovery of sperm from testicular biopsy. PMID: 17453684
30. The data show no relationship between 'gr/gr' AZC gene deletion and cryptorchidism. PMID: 17609244
31. Patients with complete Sertoli cell-only syndrome (SCOS) did not exhibit DAZ gene expression. PMID: 17881721
32. The expression of DAZ proteins in adult human testes is restricted to the spermatogonia and suggests a premeiotic role. PMID: 18385127
33. AZFc rearrangements/polymorphisms are transmitted to sons and may represent a risk factor for decreased testis function and male subfertility, which needs confirmation in further studies in larger cohorts PMID: 18440997
34. deletions of two DAZ gene copies are compatible with normal spermatogenesis and fertility. PMID: 18440997
35. PCR and FISH demonstrated tandem duplication/multiplication of the SRY and DAZ genes in the two Turner Syndrome patients having intact Y chromosome in >85% cells PMID: 19030103
36. All four DAZ genes are expressed in the human testis, and their products are highly polymorphic among men PMID: 19223287
37. human DAZL (deleted in azoospermia-like) functions in primordial germ-cell formation, whereas closely related genes DAZ and BOULE (also called BOLL) promote later stages of meiosis and development of haploid gametes PMID: 19865085
