Epigenetic modification plays key roles in spermatogenesis, especially DNA methylation dynamic is important in sustaining normal spermatogenesis. Ten-eleven translocation 1 (Tet1) is not only a key demethylase, which works in specific gene regions, but also crosstalks with partners to regulate epigenetic progress as protein complexes. Dairy goat is an(More)
Lin28a is a conserved RNA-binding protein that plays an important role in development, pluripotency, stemness maintenance, proliferation and self-renewal. Early studies showed that Lin28a serves as a marker of spermatogonial stem cells (SSCs) and promotes the proliferation capacity of mouse SSCs. However, there is little information about Lin28a in(More)
Eukaryotic translation initiation factor 2, subunit 3, and structural gene Y-linked (EIF2S3Y) is essential for spermatogenesis in mouse models. However, its effect on embryonic stem (ES) cells remains unknown. In our observation, differentiated ES cells showed higher levels of EIF2S3Y. To further elucidate its role in ES cells, we utilized ES-derived(More)
This study was performed to qualify goat fetal fibroblast (GFF) cell lines for genetic modification and somatic cell nuclear transfer (SCNT) to produce human lysozyme (hLYZ) transgenic goats. Nine GFF cell lines were established from different fetuses, and the proliferative lifespan and chromosomal stability were analyzed. The results suggested that cell(More)
By theoretical calculation and analysis, this paper studies the influence of stochastic fiber dispersion on interference stability and erroneous detected rate of quantum key distribution (QKD) system receiver, and analyses its effects on quantum key generation rates of decoy states QKD. The result shows that the interference contrast and erroneous detected(More)
Achieving high expression levels of recombinant human serum albumin (HSA) for purification is a solution for the large amount of plasma-derived HSA needed in therapeutic applications. Here, we employed phiC31 integrase system and chicken hypersensitive site-4 (cHS4) insulators to construct a HSA expression vector for high-level HSA expression. The phiC31(More)
