Summary: Somatic cell nuclear transfer (SCNT) can reprogram differentiated somatic cells into totipotency, but most SCNT blastocysts are arrested at the peri-implantation stage. In this study, a 3D in vitro culture system for SCNT peri-implantation embryos was developed, and it was found that persistent Wnt signals blocked the pluripotency transition of epiblasts, leading to defects in epiblast transformation events and implantation failure. Manipulating Wnt signals improved the cloning efficiency and enhanced the lineage developmental trajectories of SCNT blastocysts during peri-implantation development.

Summary: Inhibiting METTL5, an enzyme that methylates 18S rRNA m(6)A, during nuclear transfer can improve the developmental rate and cell number of embryos. Inhibition of METTL5 also decreases repressive histone modification levels and increases activating histone modification and mRNA levels of specific genes.

Summary: Suv39h1 and Suv39h2 are key regulators of H3K9me3 dynamics, influencing the early development of SCNT embryos. Their inhibition leads to reduced levels of H3K9me3 and altered expression of related enzymes, affecting cell proliferation and developmental competence in porcine embryos. These findings suggest that careful regulation of H3K9me3 and Suv39h1/2 levels is crucial for successful SCNT embryo development.

Summary: Assisted reproductive technology is widely used for treating human infertility, but in vitro fertilization (IVF) is associated with a low pregnancy rate and various health issues in offspring. This study reveals that IVF manipulation disrupts gene expression in extraembryonic tissues and leads to abnormal H3K4me3 modification, which is a major cause of implantation failure and abnormal placental development in IVF embryos.

Summary: Somatic cell nuclear transfer (SCNT) is a method that reprograms terminally differentiated somatic cells into totipotent embryos, but it has multiple defects. This study used MNase-seq to investigate the distribution of nucleosomes in mouse SCNT embryos and found that the dynamics of nucleosome position in SCNT embryos were delayed compared to fertilized embryos. It was also discovered that the memory of nucleosome occupancy in donor cells was a potential barrier for SCNT-mediated reprogramming.

Summary: The study found that AOA treatment affects the pre- and post-implantation embryo development in mice, resulting in increased expression of the maternal allele-specific gene Igf2r but significantly lower birth weight in newborn mice. However, no other abnormalities were observed in the offspring born following AOA treatment.

Summary: The deposition of H3K9me3 in human oocytes and early embryos has been found to be stage-specific, with enhancer-like regions being temporarily established during the 8-cell stage and greater stability during the blastocyst stage. The genes DUX and KRAB-ZNFs have been identified as potential factors involved in the establishment of stage-specific H3K9me3. Furthermore, the presence of bivalent chromatin domains in human blastocysts suggests priming for lineage differentiation.

Summary: This study found that during the process of embryo culture, the number of aneuploid cells significantly decreased and the proportion of healthy embryos significantly increased. Additionally, mitochondrial mutations may lead to decreased mitochondrial function and affect embryonic development. Therefore, analyzing the number of mitochondrial mutations may be a novel method to select better mosaic embryos for transfer.

Summary: This study provides insights into the immune landscape of Behcet's disease (BD) and highlights the contribution of C1q-high (C1q(hi)) monocytes to BD hyperinflammation. C1q(hi) monocytes demonstrate increased phagocytosis and proinflammatory cytokine secretion, and their presence is clinically relevant. Activated interferon-gamma (IFN-gamma) signaling induces the accumulation of C1q(hi) monocytes, which can be reduced by tofacitinib treatment.

Summary: Researchers have developed a multiomics computational method called BipotentR to identify cancer cell-specific regulators that modulate both tumor immunity and another oncogenic pathway. They stratified melanoma patients' response to anti-PD-1 therapy based on the tumor activities of these regulators using machine learning and deep neural approaches, enhancing the predictive power of current biomarkers. Their top regulator, ESRRA, activated in immunotherapy-resistant tumors, killed tumors by suppressing energy metabolism and activating two immune mechanisms: cytokine induction and antigen-presentation stimulation.

Summary: This study performed IFNy sensitivity screens in over 40 cancer cell lines and discovered that activation of double-strand break repair genes could lead to resistance to IFNy in cancer cells. Suppression of single-strand break repair genes increased the reliance on DSB repair genes after IFNy treatment. Inhibition of the DSB repair pathway exhibited a synergistic effect with IFNy treatment both in vitro and in vivo. The relationship between the activation of DSB repair genes and IFNy resistance was further confirmed in clinical tumor profiles. This study provides comprehensive resources and evidence to elucidate a mechanism of IFNy resistance in cancer and has the potential to inform combination therapies to overcome immunotherapy resistance.

Summary: Histone modifications play critical roles in regulating gene expression during early embryo development. This study provides the first genome-wide profiles of three key histone modifications in human primordial germ cells, revealing the positive correlation between H3K4me3 and gene expression, as well as the important roles of H3K27me3 in regulating specific promoters and X chromosome reactivation. The repressive marks of H3K9me3 and H3K27me3 jointly regulate demethylation-resistant regions in hPGCs.

It integrates multiple single-cell sequencing datasets to reveal common cell types and states in the tumor microenvironment. MetaTiME learns meta-components that encode independent components of gene expression and provides a tool to annotate cell states and gene regulators for tumor immunity and cancer immunotherapy.

Summary: This study analyzed the transcriptomes of single cells from non-small cell lung cancer patients before and after neoadjuvant PD-1 blockade combined with chemotherapy. The transcriptomes of cancer cells after treatment were associated with therapy response. Patients with major pathologic response exhibited activated antigen presentation pathways, while patients with non-major pathologic response showed overexpression of estrogen metabolism enzymes and elevated serum estradiol. The study also revealed the expansion and activation of cytotoxic T cells and NK cells after therapy, along with the reduction of immunosuppressive Tregs. The findings provide novel biomarkers for predicting therapy response and potential strategies to overcome immunotherapy resistance.
