Curr Issues Mol Biol 2024; 46:3676-3693. [PMID: 38666959 PMCID: PMC11049050 DOI: 10.3390/cimb46040229] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2024] [Revised: 04/02/2024] [Accepted: 04/17/2024] [Indexed: 04/28/2024] Open
Abstract
Artemia is a widely distributed small aquatic crustacean, renowned for its ability to enter a state of embryonic diapause. The embryonic diapause termination (EDT) is closely linked to environmental cues, but the precise underlying mechanisms remain elusive. In this study, ATAC-seq and RNA-seq sequencing techniques were employed to explore the gene expression profiles in Artemia cysts 30 min after EDT. These profiles were compared with those during diapause and 5 h after EDT. The regulatory mechanisms governing the EDT process were analyzed through Gene Ontology (GO) enrichment analysis of differentially expressed genes. Furthermore, the active G-protein-coupled receptors (GPCRs) were identified through structural analysis. The results unveiled that the signaling transduction during EDT primarily hinges on GPCRs and the cell surface receptor signaling pathway, but distinct genes are involved across different stages. Hormone-mediated signaling pathways and the tachykinin receptor signaling pathway exhibited heightened activity in the '0-30 min' group, whereas the Wnt signaling pathway manifested its function solely in the '30 min-5 h' group. These results imply a complete divergence in the mechanisms of signal regulation during these two stages. Moreover, through structural analysis, five GPCRs operating at different stages of EDT were identified. These findings provide valuable insights into the signal regulation mechanisms governing Artemia diapause.

The integrator complex subunit 11 is involved in the post-diapaused embryonic development and stress response of Artemia sinica. Gene 2020; 741:144548. [PMID: 32165292 DOI: 10.1016/j.gene.2020.144548] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2019] [Revised: 12/15/2019] [Accepted: 03/08/2020] [Indexed: 01/31/2023]
Abstract
The Integrator complex (INT) contains several subunits that participate in RNAPII transcription and the 3' end process of non-coding RNAs. INTS11 is the catalytic subunit that interacts with the C-terminal domain of RNAPII, recently found to play a role in embryo development in different experimental models. However, the involvement of INTS11 is still ignorant in crustaceans, particularly in post-diapause embryonic development of Artemia sinica. In the present research, the full-length cDNA of As-Ints11 gene (1964 bp) was cloned from A. sinica by the RACE technique. The deduced 597 amino acids sequence contains the most identifiable domains of the INTs and is highly conserved. Immunofluorescence assay showed that the INTS11 was present at diverse developmental status in A. sinica: the As-INTS11 can be found in both cytoplasm and nucleus of the embryos, and the location showed no specificity in tissue or organ of the nauplius. The expression patterns of As-Ints11 were analyzed by qPCR and Western blotting, which show similar trends that peaked at the 15 h stage of embryo development. Moreover, the expressions of interacting proteins As-INTS9 and As-RNAPII were also detected, results display a synergetic effect with the As-INTS11 at both mRNA and protein levels. We also explored the amount of As-INTS11, As-INTS9 and As-RNAPII under different stresses, and the results indicate that the As-INTS11 is a stress-related protein though the mechanism needs further research. Knocking down of the As-INTS11 resulted in a delay of post-diapaused embryonic development in A. sinica.

Investigation of the Possible Role of RAD9 in Post-Diapaused Embryonic Development of the Brine Shrimp Artemia sinica. Genes (Basel) 2019; 10:genes10100768. [PMID: 31574972 PMCID: PMC6826366 DOI: 10.3390/genes10100768] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2019] [Revised: 09/25/2019] [Accepted: 09/26/2019] [Indexed: 11/17/2022] Open
Abstract
Background: The cell cycle checkpoint protein RAD9 is a vital cell cycle regulator in eukaryotic cells. RAD9 is involved in diverse cellular functions by oligomer or monomer. However, the specific mechanism of its activity remains unknown in crustaceans, especially in embryonic diapause resumption of the brine shrimp Artemia sinica. Methods and Results: In the present article, a 1238 bp full-length cDNA of As–RAD9 gene, encoding 376 amino acids, was obtained from A. sinica. The expression pattern of As–RAD9 was analyzed by qPCR and Western blot. The mRNA expression level climbs to the top at the 10 h stage of embryo development, while the protein expression pattern is generally consistent with qPCR results. Moreover, the As–RADd9 related signaling proteins, As–RAD1, As–HUS1, As–RAD17, and As–CHK1, were also detected. Immunofluorescence assay showed that the location of As–RAD9 did not show tissue or organ specificity, and the intracellular expression was concentrated in the cytoplasm more than in the nucleus. We also explored the amount of As–RAD9 under the stresses of cold and high salinity, and the results indicate that As–RAD9 is a stress-related factor, though the mechanisms may be different in response to different stresses. Knocking down of the As–RAD9 gene led to embryonic development delay in A. sinica. Conclusions: All these results reveal that As–RAD9 is necessary for post-diapaused embryonic development in A. sinica.

Abstract
Postmenopausal osteoporosis (PMOP) is a major public health concern worldwide. The present study aimed to provide evidence to assist in the development of specific novel biomarkers for PMOP. Differentially expressed genes (DEGs) were identified between PMOP and normal controls by integrated microarray analyses of the Gene Expression Omnibus (GEO) database, and the optimal diagnostic gene biomarkers for PMOP were identified with LASSO and Boruta algorithms. Classification models, including support vector machine (SVM), decision tree and random forests models, were established to test the diagnostic value of identified gene biomarkers for PMOP. Functional annotations and protein‑protein interaction (PPI) network constructions were also conducted. Integrated microarray analyses (GSE56815, GSE13850 and GSE7429) of the GEO database were employed, and 1,320 DEGs were identified between PMOP and normal controls. An 11‑gene combination was also identified as an optimal biomarker for PMOP by feature selection and classification methods using SVM, decision tree and random forest models. This combination was comprised of the following genes: Dehydrogenase E1 and transketolase domain containing 1 (DHTKD1), osteoclast stimulating factor 1 (OSTF1), G protein‑coupled receptor 116 (GPR116), BCL2 interacting killer, adrenoceptor β1 (ADRB1), neogenin 1 (NEO1), RB binding protein 4 (RBBP4), GPR87, cylicin 2, EF‑hand calcium binding domain 1 and DEAH‑box helicase 35. RBBP4 (degree=12) was revealed to be the hub gene of this PMOP‑specific PPI network. Among these 11 genes, three genes (OSTF1, ADRB1 and NEO1) were speculated to serve roles in PMOP by regulating the balance between bone formation and bone resorption, while two genes (GPR87 and GPR116) may be involved in PMOP by regulating the nuclear factor‑κB signaling pathway. Furthermore, DHTKD1 and RBBP4 may be involved in PMOP by regulating mitochondrial dysfunction and interacting with ESR1, respectively. In conclusion, the findings of the current study provided an insight for exploring the mechanism and developing novel biomarkers for PMOP. Further studies are required to test the diagnostic value for PMOP prior to use in a clinical setting.

Abstract
High salinity and low temperatures can induce Artemia sinica to enter the diapause stage during embryonic development. Diapause embryos stop at the gastrula stage, allowing them to resist apoptosis and regulate cell cycle activity to guarantee normal development after diapause termination. P53 and DNA damage-regulated gene 1 (pdrg1) is involved in cellular physiological activities, such as apoptosis, DNA damage repair, cell cycle regulation, and promotion of programmed cell death. However, the role of pdrg1 in diapause and diapause termination in A. sinica remains unknown. Here, the full-length A. sinica pdrg1 cDNA (As-pdrg1) was obtained and found to contain 1119 nucleotides, including a 228 bp open reading frame (ORF), a 233 bp 5'-untranslated region (UTR), and a 658-bp 3'-UTR, which encodes a 75 amino acid protein. In situ hybridization showed no tissue specific expression of As-pdrg1. Quantitative real-time PCR and western blotting analyses of As-pdrg1 gene and protein expression showed high levels at 15-20 h of embryo development and a subsequent downward trend. Low temperatures upregulated As-pdrg1 expression. RNA interference for the pdrg1 gene in Artemia embryos caused significant developmental hysteresis. Thus, PDRG1 plays an important role in diapause termination and cell cycle regulation in early embryonic development of A. sinica.

Abstract
There have been many studies on dopamine active transporter (DAT) in humans and laboratory animals; however, there is a lack of information on DAT in brine shrimp. In this study, we demonstrated the neuronal and nonneuronal characteristics of DAT-synthesizing (DAT+ cells) during development of brine shrimp. In neuronal cells, the DAT+ neurons in the central body and lobes of a protocerebrum (PC) controlled the deutocerebrum. The sensory cells of nauplius eyes projected their decussated axons to the PC, and the DAT+ cells at the posterior region were associated with migration and control of the 10 posterior neurons during the early nauplius stage. In nonneuronal cells, the five types of glands, that is, the salt, antennal, mandible, and accessory glands and posterior gland1 and gland2 synthesized DAT protein. In addition, the gut and rectum dilator muscles and renal cells expressed DAT protein. Thus, DAT protein acts in the development of several types of cells during development of brine shrimp.
