RNF216 variants have been recently identified in patients with IHH. Ring finger protein 216 (RNF216), as a ubiquitin E3 ligase, catalyzes the ubiquitination of target proteins with high specificity, which consequently modulates the stability, localization, and interaction of the target protein. In this study, we found that RNF216 interacted with Staufen2 (STAU2) and affected the stability of STAU2 through the ubiquitin–proteasome pathway. STAU2, as a double-stranded RNA-binding protein enriched in the nervous system, plays a role in RNA transport, RNA stability, translation, anchoring, and synaptic plasticity. Further, we revealed that STAU2 levels in the hypothalamus of RNF216−/− mice were increased compared with wild-type (WT) mice. The change in STAU2 protein homeostasis may affect a series of RNA cargoes. Therefore, we analyzed the changes in RNA levels in the hypothalamus of RNF216−/− mice and WT mice by RNA sequencing. We found that deletion of RNF216 led to decreased activities of the prolactin signaling pathway, neuroactive ligand–receptor interaction, GnRH signaling pathway, and ovarian steroidogenesis. The weakening of these signal pathways is likely to affect the secretion of GnRH, thereby affecting the development of gonads. Therefore, our study suggests that STAU2 may be a potential therapeutic target for IHH. Further experiments are needed to demonstrate the association between the weakening of these signaling pathways and the RNA-binding protein STAU2.","PeriodicalId":50589,"journal":{"name":"Development Growth & Differentiation","volume":"65 7","pages":"408-417"},"PeriodicalIF":2.5,"publicationDate":"2023-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9941352","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the biological mechanisms of alcohol and nicotine have been studied extensively, individual differences in the response to these drugs have received little attention. Here we evaluated gene expression and behavior of bold and shy individuals after acute exposure to alcohol and nicotine. For this, zebrafish were classified as bold and shy individuals based on emergence tests, and then fish were exposed to 0.00, 0.10, and 0.50% alcohol or 0.00, 1.00, and 5.00 mg/L nicotine and their anxiety-like and locomotor behavior was observed. After behavioral assessment, brain mRNA expression (ache, bdnf, gaba1, gad1b, th1, and tph1) was evaluated. Locomotion patterns differed between profiles depending on alcohol and nicotine concentration. Anxiety increased in shy fish and decreased in bold fish after exposure to both drugs. Alcohol exposure induced an increase in tph1 mRNA expression in bold fish, while bdnf mRNA expression was increased in shy fish. Nicotine increased ache, bdnf, and tph1 mRNA levels in both profiles, but at higher levels in bold fish. Based on our research, we found that alcohol induces anxiogenic effects in both bold and shy zebrafish. Additionally, shy individuals exposed to a low concentration of nicotine exhibited stronger anxiety-like responses than their bold counterparts. These findings further support the validity of using zebrafish as a dependable tool for studying the effects of drugs and uncovering the underlying mechanisms associated with individual variations.","PeriodicalId":50589,"journal":{"name":"Development Growth & Differentiation","volume":"65 8","pages":"434-445"},"PeriodicalIF":2.5,"publicationDate":"2023-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/dgd.12876","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9883388","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we isolated and analyzed the cDNAs encoding HpCTCF, the CTCF homolog in the sea urchin Hemicentrotus pulcherrimus, to investigate its expression patterns and functions during the early development of sea urchin. HpCTCF contains nine zinc fingers corresponding to fingers 2–10 of the vertebrate CTCF. Expression pattern analysis revealed that HpCTCF mRNA was detected at all developmental stages and in the entire embryo. Upon expressing the HpCTCF-GFP fusion protein in early embryos, we observed its uniform distribution within interphase nuclei. However, during mitosis, it disappeared from the chromosomes and subsequently reassembled on the chromosome during telophase. Moreover, the morpholino-mediated knockdown of HpCTCF resulted in mitotic arrest during the morula to blastula stage. Most of the arrested chromosomes were not phospholylated at serine 10 of histone H3, indicating that mitosis was arrested at the telophase by HpCTCF depletion. Furthermore, impaired sister chromatid segregation was observed using time-lapse imaging of HpCTCF-knockdown embryos. Thus, HpCTCF is essential for mitotic progression during the early development of sea urchins, especially during the telophase-to-interphase transition. However, the normal development of pluteus larvae in CRISPR-mediated HpCTCF-knockout embryos suggests that disruption of zygotic HpCTCF expression has little effect on embryonic and larval development.","PeriodicalId":50589,"journal":{"name":"Development Growth & Differentiation","volume":"65 7","pages":"395-407"},"PeriodicalIF":2.5,"publicationDate":"2023-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9847509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, spiralian-specific TALE-type homeobox genes (SPILE) have been identified, some of which show zygotic and staggered expression patterns along the animal–vegetal axis and function in quartet specification in mollusks. However, it is unclear which maternal molecular components control the zygotic expression of these transcription factors. In this study, we focused on SPILE-E, a maternal transcription factor, and investigated its expression and function in mollusks. We found that the maternal and ubiquitous expression of SPILE-E in the cleavage stages is conserved in molluskan species, including limpets, mussels, and chitons. We knocked down SPILE-E in limpets and revealed that the expression of transcription factors specifically expressed in the first quartet (1q2; foxj1b) and second quartet (2q; SPILE-B) was abolished, whereas the macromere-quartet marker (SPILE-C) was ectopically expressed in 1q2 in SPILE-E morphants. Moreover, we showed that the expression of SPILE-A, which upregulates SPILE-B but represses SPILE-C expression, decreased in SPILE-E morphants. Consistent with changes in the expression pattern of the above transcription factors, SPILE-E-morphant larvae exhibited patchy or complete loss of expression of marker genes of ciliated cells and shell fields, possibly reflecting incomplete specification of 1q2 and 2q. Our results provide a molecular framework for quartet specification and highlight the importance of maternal lineage-specific transcription factors in the development and evolution of spiralians.","PeriodicalId":50589,"journal":{"name":"Development Growth & Differentiation","volume":"65 7","pages":"384-394"},"PeriodicalIF":2.5,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9767012","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we show that termite brain morphology changes markedly with caste differentiation and age in the termite, Reticulitermes speratus. Brain morphology was shown to be associated with reproductive division of labor, with reproductive individuals (alates and neotenic reproductives) having larger brains than nonreproductives (workers and soldiers). Micro-computed tomography (CT) imaging and dissection observations showed that the king's brain morphology changed markedly with shrinkage of the optic lobes during their long life in the dark. Behavioral experiments showed that mature primary kings lose visual function as a result of optic lobe shrinkage. These results suggested that termites restructure their nervous systems to perform necessary tasks as they undergo caste differentiation, and that they also show flexible changes in brain morphology even after the final molt. This study showed that brain morphology in social insects is linked to caste and aging, and that the evolution of the division of labor is underpinned by the development of diverse neural systems for specialized tasks.","PeriodicalId":50589,"journal":{"name":"Development Growth & Differentiation","volume":"65 7","pages":"374-383"},"PeriodicalIF":2.5,"publicationDate":"2023-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/dgd.12873","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10157950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present study, we used the clustered regularly interspaced short palindromic repeats (CRISPR)/Cas9-mediated knock-in approach to establish a transgenic medaka strain expressing the Chloromonas oogama channelrhodopsin (CoChR) in the ISL LIM homeobox 1 (isl1) locus. We demonstrated that light stimuli elicited specific behavioral responses, such as bending or turning locomotion in the embryos and pectoral fin movements in the larvae and adults. The response probabilities and intensities of these movements could be controlled by adjusting the intensity, duration, or wavelength of each light stimulus. Furthermore, we demonstrated that the pectoral fin movements in the adult stage could be elicited using a laser pointer to irradiate region including the caudal hind brain and the rostral spinal cord.

However, embryo contour extraction from images generated via light-sheet microscopy is challenging owing to the large amount of data and the variable sizes, shapes, and textures of objects. In this report, we provide a workflow for extracting the contours of zebrafish blastula and gastrula without contour labeling of an embryo. This workflow is based on the edge detection method using a change point detection approach. We assessed the performance of the edge detection method and compared it with widely used edge detection and segmentation methods. The results showed that the edge detection accuracy of the proposed method was superior to those of the Sobel, Laplacian of Gaussian, adaptive threshold, Multi Otsu, and k-means clustering-based methods, and the noise robustness of the proposed method was superior to those of the Multi Otsu and k-means clustering-based methods. The proposed workflow was shown to be useful for automating small-scale contour extractions of zebrafish embryos that cannot be specifically labeled owing to constraints, such as the availability of microscopic channels. This workflow may offer an option for contour extraction when deep learning-based approaches or existing non-deep learning-based methods cannot be applied.","PeriodicalId":50589,"journal":{"name":"Development Growth & Differentiation","volume":"65 6","pages":"311-320"},"PeriodicalIF":2.5,"publicationDate":"2023-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10411491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Expression analysis showed that sd is expressed in the tergal edge, legs, antennae, labrum, and cerci during embryogenesis and in the distal margin of the wing pads from at least the sixth instar in the mid to late stages. Because sd knockout caused early lethality, nymphal RNA interference experiments were performed. Malformations were observed in the wings, ovipositor, and antennae.

This differentiation is regulated by the Hippo signaling pathway. At the 32-cell stage, embryos establish a position-dependent distribution of the Hippo pathway coactivator, Yes-associated protein 1 (YAP, encoded by Yap1). The outer and inner cells showed nuclear and cytoplasmic localization of YAP, respectively. However, the process by which embryos establish position-dependent YAP localization remains elusive. Here, we established a YAP-reporter mouse line, Yap1mScarlet, and examined YAP–mScarlet protein dynamics during the 8–32-cell stages using live imaging. During mitosis, YAP–mScarlet diffused throughout the cells. YAP–mScarlet dynamics in daughter cells varied depending on the cell division patterns. YAP–mScarlet localization in daughter cells at the completion of cell division coincided with that in mother cells. Experimental manipulation of YAP–mScarlet localization in mother cells also altered its localization in daughter cells upon completion of cell division. In daughter cells, YAP–mScarlet localization gradually changed to the final pattern. In some divisions during the 8–16-cell stages, the cytoplasmic YAP–mScarlet localization preceded cell internalization. These results suggest that cell position is not a primary determinant of YAP localization and that the Hippo signaling status of the mother cell is inherited by the daughter cells, which likely contributes to the stabilization of the cell fate specification process beyond cell division.","PeriodicalId":50589,"journal":{"name":"Development Growth & Differentiation","volume":"65 6","pages":"360-369"},"PeriodicalIF":2.5,"publicationDate":"2023-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10097198","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Metamorphosis was studied with an emphasis on the roles of prolactin (PRL) and thyrotropin (TSH). The release of PRL was shown to be regulated by thyrotropin-releasing hormone (TRH) and that of TSH was evidenced to be regulated by corticotropin-releasing factor. The significance of the fact that the neuropeptide that controls the secretion of TSH is different from those encountered in mammals is discussed in consideration of the observation that the release of TRH, which stimulates the release of PRL, is enhanced when the animals are subjected to a cold temperature. Findings that were made by using melanin-rich cells of Bufo embryos and larvae, such as the determination of the origin of the adenohypophyseal primordium, identification of the pancreatic chitinase, and involvement of the rostral preoptic recess organ as the hypothalamic inhibitory center of α-melanocyte-stimulating hormone (α-MSH) secretion, are mentioned in this article.
