Abstract Study question Does IGF2BP3 regulate Tcf4 mRNA stability in an N6-methyladenosine (m6A)-dependent manner, affect spermatogenesis, and lead to idiopathic non-obstructive azoospermia (iNOA)? Summary answer induces apoptosis of spermatogenic cells by regulating the m6A-dependent which turn affects spermatogenesis leading iNOA. What is known already Azoospermia most serious phenotype male ...

Spermatids are the earliest male germ cells with one set of haploid chromosomes. After experiments, mainly in rodents, the spermatid injection was introduced in human assisted reproduction to the treatment of men with non-obstructive azoospermia. Spermatid injection is a technique with particular difficulties that may negatively influence the outcome. The identification, isolation and the asses...

abstract: background: the availability of testis specific genes will be of help in choosing the most promising biomarkers for the detection of testicular sperm retrieval in patients with non-obstructive azoospermia (noa). cdy1 histone acetyltransferase is a histone modifier which concentrates in the nucleus of round spermatids, where histone hyperacetylation occurs and causes the replacement of...

Piwi proteins and their guiding small RNAs, termed Piwi-interacting (pi-) RNAs, are essential for silencing of transposons in the germline of animals. A substantial fraction of piRNAs originates from genomic loci termed piRNA clusters and sequences encoded in these piRNA clusters determine putative targets for the Piwi/piRNA system. In the past decade, studies of piRNA transcriptomes in differe...
