Ubiquitin-specific protease 26 (USP26) encodes a predicted protein containing his- and cys- domains that are conserved among deubiquitinating enzymes. USP26 is specifically expressed in testis tissue and is a potential infertility gene. In this study, we performed genetic testing related to
Ubiquitin-specific protease 26 (USP26) is a deubiquitylating enzyme belonging to the USPs family with a transcription pattern restricted to the male germline. Since protein ubiquitination is an essential regulatory mechanism during meiosis, many efforts have been focused on elucidating the function
Whether the 370-371insACA, 494T>C, and 1423C>T haplotype in ubiquitin-specific protease 26 (USP26) gene is associated with male infertility is controversial. To clarify this issue, we conducted a meta-analysis based on the most recent studies. Eligible studies were screened by using PubMed and
BACKGROUND
Increased sperm ubiquitin was inversely associated with sperm count and motility. Ubiquitin-specific protease 26 (USP26), which is an X-linked gene, has been studied as a potential infertility gene. There are conflicting reports on whether variations in USP26 are associated with
Medical therapy of male infertility aims to improve or normalise the fertility status of a subfertile patient. However, this can be a frustrating task due to limited knowledge about the pathophysiology of male reproductive functions, and the fact that pharmacological therapy is mainly empirical and
The 1090C>T,L364F variant of the ubiquitin protease 26 (USP26) gene does not appear to be related to male infertility. Mutations of the USP26 gene do not appear to be a common cause of idiopathic azoospermia or severe oligozoospermia.
New male contraceptives, both hormonal and non-hormonal, have many obstacles to overcome before they reach the market as a product. For hormonal contraceptives the long-term efficacy of oligospermia in a large population of unselected men remains to be determined. For nonhormonal contraception
The Ubiquitin Specific Protease 26 gene is a testis-specific gene that is located on the X chromosome. Sequence variants of this gene were previously reported in men with azoospermia caused by defects at the level of spermatogenesis. Especially a cluster of three changes (c.370_371insACA, c.494T>C
OBJECTIVE
To investigate the transcriptional levels of four azoospermia factor genes in the testis of azoospermic men and to investigate the association between transcriptional levels and the results of sperm retrieval.
METHODS
Thirty-eight azoospermic men with normal karyotype and without Y
To purify and evaluate the molecular changes associated with an aspartic protease (Cathepsin D) in human semen from infertile subjects. Cathepsin D was purified from normo-, oligo- and azoospermic semen, by a procedure involving detergent solubilisation, affinity chromatography and gel filtration
C57BL/6N mice are inbred strains widely used in biomedical research. Hence, a large amount of basic data has been accumulated. However, in the field of histopathology, spontaneous data for relatively younger mice that are used more frequently are not yet abundant, in contrast to data for older mice
Are kallikreins (KLKs), the whey-acidic-protein four-disulfide core domain (WFDCs) and their neighbors, semenogelins (SEMGs), known to play a role in the cascade of semen coagulation and liquefaction, associated with male infertility?
Several KLK and SEMG variants are overrepresented among
Both subsets of MCs including MCTC (tryptase-positive, chymase-positive) and MCT (tryptase-positive, chymase-negative) are present in the testis and epididymis. Increased number of MCs, higher levels of MC- released tryptase in testis and seminal plasma of males with fertility
Azoospermia, characterized by the absence of spermatozoa in the ejaculate, is a common cause of male infertility with a poorly characterized etiology. Exome sequencing analysis of two azoospermic brothers allowed the identification of a homozygous splice mutation in SPINK2, encoding a serine
