J Oral Biosci 2024:S1349-0079(24)00195-6. [PMID: 39222911 DOI: 10.1016/j.job.2024.08.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2024] [Revised: 08/26/2024] [Accepted: 08/27/2024] [Indexed: 09/04/2024]
Abstract
OBJECTIVES This study aimed to investigate the effects of Y-27632 on the long-term maintainence of mouse submandibular epithelial cells (SG-Epis) in vitro and to elucidate the underlying mechanisms. METHODS The role of the Rho-associated kinase (ROCK) inhibitor Y-27632 in maintaining SG-Epis and its underlying mechanisms were evaluated by examining the in vitro expansion of mouse SG-Epis. Changes in key cellular characteristics, such as proliferation, long-term expansion, and mRNA and protein expression, were assessed in the presence or absence of Y-27632. RESULTS Treatment with Y-27632 significantly enhanced the proliferative potential of SG-Epis, preserving Krt8 and Krt14 expression over 17 passages. In the absence of Y-27632, SG-Epis lost their epithelial morphology. However, Y-27632 treatment maintained the epithelial morphology and downregulated mRNA levels of Tgf-β1, Ctgf, and Rock2. Treatment with TGF-β1 indicated that TGF-β/CTGF/p38 signaling is responsible for the maintenance of SG-Epis, while RNA interference studies revealed that ROCK2/c-Jun N-terminal kinase (JNK) signaling is also crucial for SG-Epis proliferation and maintenance. CONCLUSIONS The TGF-β1/CTGF/p38 and ROCK2/JNK signaling pathways are responsible for SG-Epis proliferation, and Y-27632 treatment effectively inactivates these pathways, enabling long-term in vitro maintenance of SG-Epis. The culture method utilizing Y-27632 provides an effective approach for the in vitro expansion of SG-Epis.

Abstract
Autoimmune myocarditis is the limited or diffuse inflammation of the myocardium due to dysfunctional cellular and humoral immunity mechanisms. We constructed mouse models of experimental autoimmune myocarditis (EAM) using peptide MyHC-α614-629. On the day after secondary immunization, the mice were intraperitoneally injected with Rho kinase (ROCK) inhibitor Y-27632. On day 21, the cardiac tissues were harvested and weighed. The hearts of EAM mice were significantly enlarged and whitened. Furthermore, body weight (BW) slowly increased during the treatment period, the heart weight (HW) and the ratio of HW/eventual BW were increased, and inflammatory infiltration and fibrosis were aggravated in the myocardial tissue. Y-27632 treatment improved the aforementioned phenotypic and pathological features of EAM mice. Mechanistic analysis revealed a significant increase in Notch1, Hes1, Jag2, Dil1, Toll-like receptor (Tlr) 2, and interleukin (IL)-1β expression in the myocardial tissue of EAM mice. Notably, IL-1β expression was correlated with that of Notch1 and Tlr2. Following Y-27632 treatment, the expression of key target genes of the Notch signaling pathway (Notch1, Hes1, Dil1, and Jag2) and Tlr2 were obviously decreased. Y-27632 treatment also decreased the number of monocytes in the spleen of EAM mice. Thus, ROCK inhibitor Y-27632 exerted a protective effect in EAM mice by downregulating IL-1β expression. This study aimed to provide a reference point for the future treatment of myocarditis in clinical settings.

De novo reconstruction of a functional in vivo-like equine endometrium using collagen-based tissue engineering. Sci Rep 2024; 14:9012. [PMID: 38641671 PMCID: PMC11031578 DOI: 10.1038/s41598-024-59471-z] [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: 02/01/2024] [Accepted: 04/11/2024] [Indexed: 04/21/2024] Open
Abstract
To better understand molecular aspects of equine endometrial function, there is a need for advanced in vitro culture systems that more closely imitate the intricate 3-dimensional (3D) in vivo endometrial structure than current techniques. However, development of a 3D in vitro model of this complex tissue is challenging. This study aimed to develop an in vitro 3D endometrial tissue (3D-ET) with an epithelial cell phenotype optimized by treatment with a Rho-associated protein kinase (ROCK) inhibitor. Equine endometrial epithelial (eECs) and mesenchymal stromal (eMSCs) cells were isolated separately, and eECs cultured in various concentrations of Rock inhibitor (0, 5, 10 µmol) in epithelial medium (EC-medium) containing 10% knock-out serum replacement (KSR). The optimal concentration of Rock inhibitor for enhancing eEC proliferation and viability was 10 µM. However, 10 µM Rock inhibitor in the 10% KSR EC-medium was able to maintain mucin1 (Muc1) gene expression for only a short period. In contrast, fetal bovine serum (FBS) was able to maintain Muc1 gene expression for longer culture durations. An in vitro 3D-ET was successfully constructed using a collagen-based scaffold to support the eECs and eMSCs. The 3D-ET closely mimicked in vivo endometrium by displaying gland-like eEC-derived structures positive for the endometrial gland marker, Fork headbox A2 (FOXA2), and by mimicking the 3D morphology of the stromal compartment. In addition, the 3D-ET expressed the secretory protein MUC1 on its glandular epithelial surface and responded to LPS challenge by upregulating the expression of the interleukin-6 (IL6) and prostaglandin F synthase (PGFS) genes (P < 0.01), along with an increase in their secretory products, IL-6 (P < 0.01) and prostaglandin F2alpha (PGF2α) (P < 0.001) respectively. In the future, this culture system can be used to study both normal physiology and pathological processes of the equine endometrium.

ROCK Inhibitor (Y-27632) Abolishes the Negative Impacts of miR-155 in the Endometrium-Derived Extracellular Vesicles and Supports Embryo Attachment. Cells 2022; 11:cells11193178. [PMID: 36231141 PMCID: PMC9564368 DOI: 10.3390/cells11193178] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2022] [Revised: 10/07/2022] [Accepted: 10/07/2022] [Indexed: 11/16/2022] Open
Abstract
Extracellular vesicles (EVs) are nanosized vesicles that act as snapshots of cellular components and mediate cellular communications, but they may contain cargo contents with undesired effects. We developed a model to improve the effects of endometrium-derived EVs (Endo-EVs) on the porcine embryo attachment in feeder-free culture conditions. Endo-EVs cargo contents were analyzed using conventional and real-time PCR for micro-RNAs, messenger RNAs, and proteomics. Porcine embryos were generated by parthenogenetic electric activation in feeder-free culture conditions supplemented with or without Endo-EVs. The cellular uptake of Endo-EVs was confirmed using the lipophilic dye PKH26. Endo-EVs cargo contained miR-100, miR-132, and miR-155, together with the mRNAs of porcine endogenous retrovirus (PERV) and β-catenin. Targeting PERV with CRISPR/Cas9 resulted in reduced expression of PERV mRNA transcripts and increased miR-155 in the Endo-EVs, and supplementing these in embryos reduced embryo attachment. Supplementing the medium containing Endo-EVs with miR-155 inhibitor significantly improved the embryo attachment with a few outgrowths, while supplementing with Rho-kinase inhibitor (RI, Y-27632) dramatically improved both embryo attachment and outgrowths. Moreover, the expression of miR-100, miR-132, and the mRNA transcripts of BCL2, zinc finger E-box-binding homeobox 1, β-catenin, interferon-γ, protein tyrosine phosphatase non-receptor type 1, PERV, and cyclin-dependent kinase 2 were all increased in embryos supplemented with Endo-EVs + RI compared to those in the control group. Endo-EVs + RI reduced apoptosis and increased the expression of OCT4 and CDX2 and the cell number of embryonic outgrowths. We examined the individual and combined effects of RI compared to those of the miR-155 mimic and found that RI can alleviate the negative effects of the miR-155 mimic on embryo attachment and outgrowths. EVs can improve embryo attachment and the unwanted effects of the de trop cargo contents (miR-155) can be alleviated through anti-apoptotic molecules such as the ROCK inhibitor.

Abstract
The development of therapies to prevent or treat salivary gland dysfunction has been limited by a lack of functional in vitro models. Specifically, critical markers of salivary gland secretory phenotype downregulate rapidly ex vivo. Here, we utilize a salivary gland tissue chip model to conduct a design of experiments (DoE) approach to test combinations of seven soluble cues that were previously shown to maintain or improve salivary gland cell function. This approach uses statistical techniques to improve efficiency and accuracy of combinations of factors. The DoE-designed culture conditions improve markers of salivary gland function. Data show that the EGFR inhibitor, EKI-785, maintains relative mRNA expression of Mist1, a key acinar cell transcription factor, while FGF10 and neurturin promote mRNA expression of Aqp5 and Tmem16a, channel proteins involved in secretion. Mist1 mRNA expression correlates with increased secretory function, including calcium signaling and mucin (PAS-AB) staining. Overall, this study demonstrates that media conditions can be efficiently optimized to support secretory function in vitro using a DoE approach.

Abstract
BACKGROUND Human dental pulp stem cells (hDPSCs) possess mesenchymal stem cell properties, originating from migrating neural crest cells. hDPSCs have received extensive attention in the field of tissue engineering and regenerative medicine due to their accessibility and ability to differentiate in several cell phenotypes. In this study, we cultured hDPSCs with Y-27632 to observe their biological behaviors changes. METHODS The hDPSCs were separately cultured with Y-27632 (0, 0.156, 0.312, 0.625, 1.25, 2.50, 5, 10, 20, 40 μm) for 24, 48, 72 h to select the suitable concentration and time using CCK-8. Then, the hDPSCs were cultured with 2.50 μm Y-27632 for 48 h to analyzed the biological behaviors changes by 5-Ethynyl-2'-deoxyuridine (EdU), plate cloning, transwell, scratch, and Annexin V FITC/PI assays, separately. Additionally, osteogenic calcium nodules and lipid droplets were analyzed using alizarin red staining and oil red O staining, respectively. qRT-PCR was used to analyze the expression of osteogenesis, adipogenesis, stemness maintenance, and inflammation related genes. RESULTS The hDPSCs proliferation was significantly enhanced after cultured with 2.50 μm Y-27632 for 48 h, but there was no significant difference in migration and apoptosis. Observation of alkaline phosphatase (ALP) activity, osteogenic and adipogenic differentiation abilities of hDPSCs, Y-27632 treatment clearly decreased the ALP activity and osteogenic differentiation ability, increased the adipogenic differentiation ability. Furthermore, Y-27632 decreased the CD73, CD90, CD105, CD166, TLR4, and NF-κB p65 genes expression, but increased the IL-8 gene expression. CONCLUSIONS The biological behaviors of hDPSCs could be changed when they cultured with Y-27632.
