LGR signaling mediates muscle-adipose tissue crosstalk and protects against diet-induced insulin resistance. Nat Commun 2024; 15:6126. [PMID: 39033139 PMCID: PMC11271308 DOI: 10.1038/s41467-024-50468-w] [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: 09/04/2023] [Accepted: 07/04/2024] [Indexed: 07/23/2024] Open
Abstract
Obesity impairs tissue insulin sensitivity and signaling, promoting type-2 diabetes. Although improving insulin signaling is key to reversing diabetes, the multi-organ mechanisms regulating this process are poorly defined. Here, we screen the secretome and receptome in Drosophila to identify the hormonal crosstalk affecting diet-induced insulin resistance and obesity. We discover a complex interplay between muscle, neuronal, and adipose tissues, mediated by Bone Morphogenetic Protein (BMP) signaling and the hormone Bursicon, that enhances insulin signaling and sugar tolerance. Muscle-derived BMP signaling, induced by sugar, governs neuronal Bursicon signaling. Bursicon, through its receptor Rickets, a Leucine-rich-repeat-containing G-protein coupled receptor (LGR), improves insulin secretion and insulin sensitivity in adipose tissue, mitigating hyperglycemia. In mouse adipocytes, loss of the Rickets ortholog LGR4 blunts insulin responses, showing an essential role of LGR4 in adipocyte insulin sensitivity. Our findings reveal a muscle-neuronal-fat-tissue axis driving metabolic adaptation to high-sugar conditions, identifying LGR4 as a critical mediator in this regulatory network.

The evolving roles of Wnt signaling in stem cell proliferation and differentiation, the development of human diseases, and therapeutic opportunities. Genes Dis 2024; 11:101026. [PMID: 38292186 PMCID: PMC10825312 DOI: 10.1016/j.gendis.2023.04.042] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2022] [Revised: 03/18/2023] [Accepted: 04/12/2023] [Indexed: 02/01/2024] Open
Abstract
The evolutionarily conserved Wnt signaling pathway plays a central role in development and adult tissue homeostasis across species. Wnt proteins are secreted, lipid-modified signaling molecules that activate the canonical (β-catenin dependent) and non-canonical (β-catenin independent) Wnt signaling pathways. Cellular behaviors such as proliferation, differentiation, maturation, and proper body-axis specification are carried out by the canonical pathway, which is the best characterized of the known Wnt signaling paths. Wnt signaling has emerged as an important factor in stem cell biology and is known to affect the self-renewal of stem cells in various tissues. This includes but is not limited to embryonic, hematopoietic, mesenchymal, gut, neural, and epidermal stem cells. Wnt signaling has also been implicated in tumor cells that exhibit stem cell-like properties. Wnt signaling is crucial for bone formation and presents a potential target for the development of therapeutics for bone disorders. Not surprisingly, aberrant Wnt signaling is also associated with a wide variety of diseases, including cancer. Mutations of Wnt pathway members in cancer can lead to unchecked cell proliferation, epithelial-mesenchymal transition, and metastasis. Altogether, advances in the understanding of dysregulated Wnt signaling in disease have paved the way for the development of novel therapeutics that target components of the Wnt pathway. Beginning with a brief overview of the mechanisms of canonical and non-canonical Wnt, this review aims to summarize the current knowledge of Wnt signaling in stem cells, aberrations to the Wnt pathway associated with diseases, and novel therapeutics targeting the Wnt pathway in preclinical and clinical studies.

Chen S, Xiao Z, Jiang W. SOX2 suppresses osteoblast differentiation of MC3T3-E1 cells through activating the transcription of LGR4. In Vitro Cell Dev Biol Anim 2023; 59:1-9. [PMID: 36547788 DOI: 10.1007/s11626-022-00740-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Accepted: 11/19/2022] [Indexed: 12/24/2022]
Abstract
Osteogenic differentiation is a crucial process of new bone formation. This study aimed to explore the roles and mechanism of SRY-Box Transcription Factor 2 (SOX2) on proliferation and osteogenic differentiation of MC3T3-E1 cells. Bone morphogenetic protein 2 (BMP2) was used to induce the osteogenic differentiation of MC3T3-E1 cells. The expression of SOX2 was determined by quantitative real-time PCR (RT-PCR) at different time points after induction. The SOX2 overexpression plasmids were constructed and transfected into MC3T3-E1 cells. Osteogenic differentiation was evaluated by Alizarin Red S staining and alkaline phosphatase (ALP) assay. The expressions of osteogenic differentiation markers including runt-related transcription factor 2 (Runx2), osteopontin (OPN), and osteocalcin (OCN) were detected by western blot assay. Luciferase reporter and CHIP assays were used to confirm that SOX2 regulated the transcriptional activation of leucine-rich repeat-containing G protein-coupled receptor 4 (LGR4). We found that SOX2 was down-regulated upon BMP2-induced osteogenic differentiation in MC3T3-E1 cells. Overexpression of SOX2 effectively inhibited osteogenic differentiation with decreased ALP activity, calcification, and osteogenic differentiation markers' expression including Runx2, OPN, and OCN. LGR4 was identified as a target of SOX2, and the inhibitory effect of SOX2 on osteogenic differentiation was reversed by knockdown of LGR4. The present study confirmed that SOX2 suppressed osteogenic differentiation of MC3T3-E1 cells through targeting LGR4, which possesses a therapeutic strategy for bone formation and generation.

Abstract
The leucine-rich repeats containing G protein-coupled receptor 4 (LGR4) belonging to G protein-coupled receptors (GPCRs) family, had various regulatory roles at multiple cellular types and numerous targeting sites, and aberrant LGR4 signaling played crucial roles in diseases and carcinogenesis. On the basis of these facts, LGR4 may become an appealing therapeutic target for the treatment of diseases and tumors. However, a comprehensive investigation of its functions and applications was still lacking. Hence, this paper provided an overview of the molecular characteristics and signaling mechanisms of LGR4, its involvement in multiple organ development and participation in the modulation of immunology related diseases, metabolic diseases, and oxidative stress damage along with cancer progression. Given that GPCRs accounted for almost a third of current clinical drug targets, the in-depth understanding of the sophisticated connections of LGR4 and its ligands would not only enrich their regulatory networks, but also shed new light on designing novel molecular targeted drugs and small molecule blockers for revolutionizing the treatment of various diseases and tumors.
