Abstract
This review describes in detail the morphological, cytoskeletal and gene expression events leading to the gene regulatory network bifurcation point of trophoblast and inner cell mass cells in a variety of mammalian preimplantation embryos. The interrelated processes of compaction and polarity establishment are discussed in terms of how they affect YAP/WWTR activity and the location and fate of cells. Comparisons between mouse, human, cattle, pig and rabbit embryos suggest a conserved role for YAP/WWTR signalling in trophoblast induction in eutherian animals though the mechanisms for, and timing of, YAP/WWTR activation differs among species. Downstream targets show further differences, with the trophoblast marker GATA3 being a direct target in all examined mammals, while CDX2-positive and SOX2-negative regulation varies.

Yang B, Xu Z, Qin Y, Peng Y, Luo Y, Wang J. Exploring the effects of Hippo signaling pathway on rumen epithelial proliferation. BMC Vet Res 2024; 20:186. [PMID: 38730465 PMCID: PMC11084078 DOI: 10.1186/s12917-024-04067-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2023] [Accepted: 05/07/2024] [Indexed: 05/12/2024] Open
Abstract
BACKGROUND The current understanding to the mechanism of rumen development is limited. We hypothesized that the Hippo signaling pathway controlled the proliferation of rumen epithelium (RE) during postnatal development. In the present study, we firstly tested the changes of the Hippo signaling pathway in the RE during an early growing period from d5 to d25, and then we expanded the time range to the whole preweaning period (d10-38) and one week post weaning (d45). An in vitro experiment was also carried out to verify the function of Hippo signaling pathway during RE cell proliferation. RESULTS In the RE of lambs from d5 to d25, the expression of baculoviral IAP repeat containing (BIRC3/5) was increased, while the expressions of large tumor suppressor kinase 2 (LATS2), TEA domain transcription factor 3 (TEAD3), axin 1 (AXIN1), and MYC proto-oncogene (MYC) were decreased with rumen growth. From d10 to d38, the RE expressions of BIRC3/5 were increased, while the expressions of LATS2 and MYC were decreased, which were similar with the changes in RE from d5 to d25. From d38 to d45, different changes were observed, with the expressions of LATS1/2, MOB kinase activator 1B (MOB1B), and TEAD1 increased, while the expressions of MST1 and BIRC5 decreased. Correlation analysis showed that during the preweaning period, the RE expressions of BIRC3/5 were positively correlated with rumen development variables, while LAST2 was negatively correlated with rumen development variables. The in vitro experiment validated the changes of LATS2 and BIRC3/5 in the proliferating RE cells, which supported their roles in RE proliferation during preweaning period. CONCLUSIONS Our results suggest that the LATS2-YAP1-BIRC3/5 axis participates in the RE cell proliferation and promotes rumen growth during the preweaning period.

Abstract
Monochorionic twinning of human embryos increases the risk of complications during pregnancy. The rarity of such twinning events, combined with ethical constraints in human embryo research, makes investigating the mechanisms behind twinning practically infeasible. As a result, there is a significant knowledge gap regarding the origins and early phenotypic presentation of monochorionic twin embryos. In this study, a microthermoformed-based microwell screening platform is used to identify conditions that efficiently induce monochorionic twins in human stem cell-based blastocyst models, termed "twin blastoids". These twin blastoids contain a cystic GATA3+ trophectoderm-like epithelium encasing two distinct inner cell masses (ICMs). Morphological and morphokinetic analyses reveal that twinning occurs during the cavitation phase via splitting of the OCT4+ pluripotent core. Notably, each ICM in twin blastoids contains its own NR2F2+ polar trophectoderm-like region, ready for implantation. This is functionally tested in a microfluidic chip-based implantation assay with epithelial endometrium cells. Under defined flow regimes, twin blastoids show increased adhesion capacity compared to singleton blastoids, suggestive of increased implantation potential. In conclusion, the development of technology enabling large-scale formation of twin blastoids, coupled with high-sensitivity readout capabilities, presents an unprecedented opportunity for systematically exploring monochorionic twin formation and its impact on embryonic development.

Abstract
The improvement of in vitro embryo development is a gateway to enhance the output of assisted reproductive technologies. The Wnt and Hippo signaling pathways are crucial for the early development of bovine embryos. This study investigated the development of bovine embryos under the influence of a Hippo signaling agonist (LPA) and a Wnt signaling inhibitor (DKK1). In this current study, embryos produced in vitro were cultured in media supplemented with LPA and DKK1. We comprehensively analyzed the impact of LPA and DKK1 on various developmental parameters of the bovine embryo, such as blastocyst formation, differential cell counts, YAP fluorescence intensity and apoptosis rate. Furthermore, single-cell RNA sequencing (scRNA-seq) was employed to elucidate the in vitro embryonic development. Our results revealed that LPA and DKK1 improved the blastocyst developmental potential, total cells, trophectoderm (TE) cells and YAP fluorescence intensity and decreased the apoptosis rate of bovine embryos. A total of 1203 genes exhibited differential expression between the control and LPA/DKK1-treated (LD) groups, with 577 genes upregulated and 626 genes downregulated. KEGG pathway analysis revealed significant enrichment of differentially expressed genes (DEGs) associated with TGF-beta signaling, Wnt signaling, apoptosis, Hippo signaling and other critical developmental pathways. Our study shows the role of LPA and DKK1 in embryonic differentiation and embryo establishment of pregnancy. These findings should be helpful for further unraveling the precise contributions of the Hippo and Wnt pathways in bovine trophoblast formation, thus advancing our comprehension of early bovine embryo development.

LncRNA H19-rich extracellular vesicles derived from gastric cancer stem cells facilitate tumorigenicity and metastasis via mediating intratumor communication network. J Transl Med 2023; 21:238. [PMID: 37005676 PMCID: PMC10067256 DOI: 10.1186/s12967-023-04055-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2022] [Accepted: 03/10/2023] [Indexed: 04/04/2023] Open
Abstract
BACKGROUND Extracellular vesicles (EVs) transport biologically active molecules, and represent a recently identified way of intercellular communication. Recent evidence has also reported that EVs shed by cancer stem cells (CSCs) make a significant contribution to carcinogenesis and metastasis. Here, this study aims to explore the possible molecular mechanism of CSCs-EVs in gastric cancer (GC) by mediating intratumor communication network. METHODS CSCs and non-stem cancer cells (NSCCs) were sorted from GC cells, and EVs were isolated from CSCs. H19 was knocked down in CSCs, and CSCs-EVs or CSCs-EVs containing shRNA-H19 (CSCs-EVs-sh-H19) were co-cultured with NSCCs, followed by evaluation of the malignant behaviors and stemness of NSCCs. Mouse models of GC were established and injected with CSCs-EVs from sh-H19-treated NSCCs in vivo. RESULTS CSCs had notable self-renewal and tumorigenic capacity compared with NSCCs. CSCs promoted the malignant behaviors of NSCCs and expression of stemness marker proteins through secretion of EVs. Inhibited secretion of CSCs-EVs curtailed the tumorigenicity and metastasis of NSCCs in vivo. H19 could be delivered by CSCs-EVs into NSCCs. H19 promoted the malignant behaviors of NSCCs and stemness marker protein expression in vitro along with tumorigenicity and liver metastasis in vivo, which was mechanistically associated with activation of the YAP/CDX2 signaling axis. CONCLUSION Taken together, the present study points to the importance of a novel regulatory axis H19/YAP/CDX2 in carcinogenic and metastatic potential of CSCs-EVs in GC, which may be potential targets for anticancer therapy.

Abstract
The embryo instructs the allocation of cell states to spatially regulate functions. In the blastocyst, patterning of trophoblast (TR) cells ensures successful implantation and placental development. Here, we defined an optimal set of molecules secreted by the epiblast (inducers) that captures in vitro stable, highly self-renewing mouse trophectoderm stem cells (TESCs) resembling the blastocyst stage. When exposed to suboptimal inducers, these stem cells fluctuate to form interconvertible subpopulations with reduced self-renewal and facilitated differentiation, resembling peri-implantation cells, known as TR stem cells (TSCs). TESCs have enhanced capacity to form blastoids that implant more efficiently in utero due to inducers maintaining not only local TR proliferation and self-renewal, but also WNT6/7B secretion that stimulates uterine decidualization. Overall, the epiblast maintains sustained growth and decidualization potential of abutting TR cells, while, as known, distancing imposed by the blastocyst cavity differentiates TR cells for uterus adhesion, thus patterning the essential functions of implantation.

The Hippo pathway effectors YAP and TAZ interact with EGF-like signaling to regulate expansion-related events in bovine cumulus cells in vitro. J Assist Reprod Genet 2022; 39:481-492. [PMID: 35091965 PMCID: PMC8956774 DOI: 10.1007/s10815-021-02384-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2021] [Accepted: 12/17/2021] [Indexed: 02/03/2023] Open
Abstract
PURPOSE To determine if the inhibition of the interaction between the Hippo effector YAP or its transcriptional co-activator TAZ with the TEAD family of transcription factors is critical for the cumulus expansion-related events induced by the EGF network in cumulus-oocyte complexes (COCs). METHODS We performed a series of experiments using immature bovine COCs subjected to an IVM protocol for up 24 h in which cumulus expansion was stimulated with EGF recombinant protein or FSH. RESULTS The main results indicated that EGFR activity stimulation in bovine cumulus cells (CC) increases mRNA levels encoding the classic YAP/TAZ-TEAD target gene CTGF. To determine if important genes for cumulus expansion are transcriptional targets of YAP/TAZ-TEAD interaction in CC, COCs were then subjected to IVM in the presence of FSH with or without distinct concentrations of Verteporfin (VP; a small molecule inhibitor that interferes with YAP/TAZ binding to TEADs). COCs were then collected at 6, 12, 18, and 24 h for total RNA extraction and RT-qPCR analyses. This experiment indicated that VP inhibits in a time- and concentration-dependent manner distinct cumulus expansion and oocyte maturation-related genes, by regulating EGFR and CTGF expression in CC. CONCLUSIONS Taken together, the results presented herein represent considerable insight into the functional relevance of a completely novel signaling pathway underlying cumulus expansion and oocyte maturation in monovulatory species. YAP/TAZ or CTGF may represent potential targets to improve the efficiency of IVM systems, not only for monovulatory species of agricultural importance as the cow, but for human embryo production.
