Overexpression of KAT8 induces a failure in early embryonic development in mice.

Embryo quality is strongly associated with subsequent embryonic developmental efficiency. However, the detailed function of lysine acetyltransferase 8 (KAT8) during early embryonic development in mice remains elusive. In this study, we reported that KAT8 played a pivotal role in the first cleavage of mouse embryos.

KAT8 functions in redox homeostasis and mitochondrial dynamics during mouse oocyte meiosis progression.

As a histone acetyltransferase, lysine acetyltransferase 8 (KAT8) participates in diverse biological processes. However, the effect of KAT8 on oocyte maturation in mice remains unclear. In this study, we found that mouse oocytes overexpressing Kat8-OE induced maturation failure manifested reduced rates of GVBD and first polar body emission.

A study on the tourism efficiency of tourism destination based on DEA model: A case of ten cities in Shaanxi province.

Exploring the of regional tourism efficiency is of great significance in promoting high-quality development of regional tourism. However, there are not many studies that measure the quality development of tourism destinations from the perspective of inputs and output. Based on this, the data envelopment analysis model is used to measure the overall technical efficiency (TECRS), pure technical efficiency (TEVRS), and scale efficiency (SE) with the help of DEA-SOLVER software, taking the ten prefecture-level cities in Shaanxi Province as examples, to further analyze and evaluate the spatial differences of different tourism destinations and the reasons for the differences.

NET1 is a critical regulator of spindle assembly and actin dynamics in mouse oocytes.

Background: Neuroepithelial transforming gene 1 (NET1) is a RhoA subfamily guanine nucleotide exchange factor that governs a wide array of biological processes. However, its roles in meiotic oocyte remain unclear. We herein demonstrated that the NET1-HACE1-RAC1 pathway mediates meiotic defects in the progression of oocyte maturation.

A human-specific insertion promotes cell proliferation and migration by enhancing TBC1D8B expression.

Human-specific insertions play important roles in human phenotypes and diseases. Here we reported a 446-bp insertion (Insert-446) in intron 11 of the TBC1D8B gene, located on chromosome X, and traced its origin to a portion of intron 6 of the EBF1 gene on chromosome 5. Interestingly, Insert-446 was present in the human Neanderthal and Denisovans genomes, and was fixed in humans after human-chimpanzee divergence.

Effect of different manual puncture methods on donkey embryo before vitrification.

The application of embryo recovery and transfer technology in the donkey industry is far lower than that of horses and cattle. Sometimes the recovered embryos could not be transferred in time, which required embryo cryopreservation. The embryo cryopreservation technology is more conducive to the preservation and transportation of recovered embryos with excellent genetic traits.

Role of FBXL5 in redox homeostasis and spindle assembly during oocyte maturation in mice.

As an E3 ubiquitin ligase, F-box and leucine-rich repeat protein 5 (FBXL5) participates in diverse biologic processes. However, the role of Fbxl5 in mouse oocyte meiotic maturation has not yet been fully elucidated. The present study revealed that mouse oocytes depleted of Fbxl5 were unable to complete meiosis, as Fbxl5 silencing led to oocyte meiotic failure with reduced rates of GVBD and polar body extrusion.
