Project description:The functional role of the maternal protein during early embryo development remains to be elucidated. Here we show that the maternal protein, Rbpms2, is highly expressed in mouse oocytes and that knockdown of Rbpms2 inhibits development from the morula to blastocyst stage. To study the underlying mechanism, we firstly analysed the differential expressed genes after Rbpms2 knockdown through single-cell sequencing. Combined the bioinformatics analysis of sequencing data, we then identify the impaired location of E-cadherin after knockdown of Rbpms2 may leading to the morula arrested development . Furthermore, Rbpms2 is important for development of mouse early embryos, most likely because it activates the BMP pathway. Taken together, our study uncovers that Rbpms2 activate the BMP pathway, and thus adjust the location of E-cadherin which is important for mouse early embryos development.

Project description:In this study we aimed to examine the effect of alternative in vivo and in vitro culture conditions during the time of blastocyst formation on the transcriptome profile of bovine blastocysts. Two different blastocyst groups were produced. The first group (Vitro_morula) was matured, fertilized and cultured in vitro until morula stage then transferred to synchronized recipients and blastocysts were collected at day 7 by uterine flushing. The second group (Vivo_morula) was matured, fertilized and cultured in vivo until morula stage then flushed out and cultured in vitro until day 7. Complete in vitro (IVP) and in vivo blastocysts were produced and used as controls.

Project description:In order to control transposable element (TE) activity, PIWI-interacting RNAs (piRNAs) have been evolved to silence TE transcriptionally and post-transcriptionally, and produced from heterochromatic genomic loci, called piRNA cluster. Maternal inherited piRNAs transmission is considered as the key step of piRNA cluster maintenance and induction of de nove piRNA cluster formation, however, how the original piRNAs were produced without maternal piRNAs deposition remains unclear. In this paper, we created a repetitive GFP reporter and found a Rhino-dependent piRNA cluster conversion spontaneously occurs to the reporter over generations. Importantly, this conversion is reversible by removal of maternal piRNAs of GFP reporter. Taking advantage of this reversible GFP reporter piRNA cluster, we found that siRNA is able to initiate piRNA cluster formation epigenetically, even when only maternal siRNA presence is capable to do so. Our results suggest the importance of siRNA on initiation of piRNA biogenesis and describe a whole picture of initiation and maintenance of piRNA cluster.

Project description:BackgroundAdvanced models including time-lapse imaging and artificial intelligence technologies have been used to predict blastocyst formation. However, the conventional morphological evaluation of embryos is still widely used. The purpose of the present study was to evaluate the predictive power of conventional morphological evaluation regarding blastocyst formation.MethodsRetrospective evaluation of data from 15,613 patients receiving blastocyst culture from January 2013 through December 2020 in our institution were reviewed. Generalized estimating equations (GEE) were used to establish the morphology-based model. To estimate whether including more features regarding patient characteristics and cycle parameters improve the predicting power, we also establish models including 27 more features with either LASSO regression or XGbosst. The predicted number of blastocyst were associated with the observed number of the blastocyst and were used to predict the blastocyst transfer cancellation either in fresh or frozen cycles.ResultsBased on early cleavage and routine observed morphological parameters (cell number, fragmentation, and symmetry), the GEE model predicted blastocyst formation with an AUC of 0.779(95%CI: 0.77-0.787) and an accuracy of 74.7%(95%CI: 73.9%-75.5%) in the validation set. LASSO regression model and XGboost model based on the combination of cycle characteristics and embryo morphology yielded similar predicting power with AUCs of 0.78(95%CI: 0.771-0.789) and 0.754(95%CI: 0.745-0.763), respectively. For per-cycle blastocyst yield, the predicted number of blastocysts using morphological parameters alone strongly correlated with observed blastocyst number (r = 0.897, P < 0.0001) and predicted blastocyst transfer cancel with an AUC of 0.926((95%CI: 0.911-0.94).ConclusionThe data suggested that routine morphology observation remained a feasible tool to support an informed decision regarding the day of transfer. However, models based on the combination of cycle characteristics and embryo morphology do not increase the predicting power significantly.

Project description:Sterol 27-hydroxylase (Cyp27a1) is a primary enzyme that is involved in the Alternative pathway of bile acid synthesis, which is particularly enhanced during pregnancy. However, the role of this enzyme during fetal organ formation was unclear. Here, we demonstrate that 27-hydroxylase activity in the mother is essential for the progression of pregnancy and organ formation in the fetuses. Maternal depletion of Cyp27a1 reduced success pregnancy rate and litter size. In addition, all of the delivered newborn mice died due to respiratory distress syndrome resulting from the absence of mature alveolar epithelial cells. These phenotypes were caused by 7α-hydroxycholesterol (7α-HC) accumulating in Cyp27a1 deficient mice. Mechanistically, 7α-HC bound to and destabilized a protein Fau, mediating the assembly of ribosomes, the down-regulation of which led to lower protein synthesis and polysome formation. Our study discovered the essential metabolic pathway protecting the developing fetuses from a toxic metabolite.
