Abstract
Diabetes-related bone loss represents a significant complication that persistently jeopardizes the bone health of individuals with diabetes. Primary cilia proteins have been reported to play a vital role in regulating osteoblast differentiation in diabetes-related bone loss. However, the specific contribution of KIAA0753, a primary cilia protein, in bone loss induced by diabetes remains unclear. In this investigation, we elucidated the pivotal role of KIAA0753 as a promoter of osteoblast differentiation in diabetes. RNA sequencing demonstrated a marked downregulation of KIAA0753 expression in pro-bone MC3T3 cells exposed to a high glucose environment. Diabetes mouse models further validated the downregulation of KIAA0753 protein in the femur. Diabetes was observed to inhibit osteoblast differentiation in vitro, evidenced by downregulating the protein expression of OCN, OPN and ALP, decreasing primary cilia biosynthesis, and suppressing the Hedgehog signalling pathway. Knocking down KIAA0753 using shRNA methods was found to shorten primary cilia. Conversely, overexpression KIAA0753 rescued these changes. Additional insights indicated that KIAA0753 effectively restored osteoblast differentiation by directly interacting with SHH, OCN and Gli2, thereby activating the Hedgehog signalling pathway and mitigating the ubiquitination of Gli2 in diabetes. In summary, we report a negative regulatory relationship between KIAA0753 and diabetes-related bone loss. The clarification of KIAA0753's role offers valuable insights into the intricate mechanisms underlying diabetic bone complications.

ARL13B promotes cell cycle through the sonic hedgehog signaling pathway to alleviate nerve damage during cerebral ischemia/reperfusion in rats. Biochem Pharmacol 2024; 227:116446. [PMID: 39038552 DOI: 10.1016/j.bcp.2024.116446] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2024] [Revised: 07/17/2024] [Accepted: 07/18/2024] [Indexed: 07/24/2024]
Abstract
Cerebral ischemia/reperfusion (CIRI) is a leading cause of death worldwide. A small GTPase known as ADP-ribosylation factor-like protein 13B (ARL13B) is essential in several illnesses. The role of ARL13B in CIRI remains unknown, though. A middle cerebral artery occlusion/reperfusion (MCAO/R) in rats as well as an oxygen-glucose deprivation/reoxygenation (OGD/R) models in PC12 cells were constructed. The neuroprotective effects of ARL13B against MCAO/R were evaluated using neurological scores, TTC staining, rotarod testing, H&E staining, and Nissl staining. To detect the expression of proteins associated with the SHH pathway and apoptosis, western blotting and immunofluorescence were employed. Apoptosis was detected using TUNEL assays and flow cytometry. There was increased expression of ARL13B in cerebral ischemia/reperfusion models. However, ARL13B knockdown aggravated CIRI nerve injury by inhibiting the sonic hedgehog (SHH) pathway. In addition, the use of SHH pathway agonist (SAG) can increased ARL13B expression, reverse the effects of ARL13B knockdown exacerbating CIRI nerve injury. ARL13B alleviated cerebral infarction and pathological injury and played a protective role against MCAO/R. Furthermore, ARL13B significantly increased the expression of SHH pathway-related proteins and the anti-apoptotic protein BCL-2, while decreased the expression of pro-apoptotic protein BAX, thus reducing apoptosis. The results from the OGD/R model in PC12 cells were consistent with those obtained in vivo. Surprisingly, we demonstrated that ARL13B regulates the cell cycle to protect against CIRI nerve injury. Our findings indicate that ARL13B protects against CIRI by reducing apoptosis through SHH-dependent pathway activation, and suggest that ARL13B plays a crucial role in CIRI pathogenesis.

Abstract
Surgical reattachment of tendon to bone is a clinical challenge, with unacceptably high retear rates in the early period after repair. A primary reason for these repeated tears is that the multiscale toughening mechanisms found at the healthy tendon enthesis are not regenerated during tendon-to-bone healing. The need for technologies to improve these outcomes is pressing, and the tissue engineering community has responded with many advances that hold promise for eventually regenerating the multiscale tissue interface that transfers loads between the two dissimilar materials, tendon, and bone. This review provides an assessment of the state of these approaches, with the aim of identifying a critical agenda for future progress.

Abstract
PURPOSE OF REVIEW Interfacial tissue exists throughout the body at cartilage-to-bone (osteochondral interface) and tendon-to-bone (enthesis) interfaces. Healing of interfacial tissues is a current challenge in regenerative approaches because the interface plays a critical role in stabilizing and distributing the mechanical stress between soft tissues (e.g., cartilage and tendon) and bone. The purpose of this review is to identify new directions in the field of interfacial tissue development and physiology that can guide future regenerative strategies for improving post-injury healing. RECENT FINDINGS Cues from interfacial tissue development may guide regeneration including biological cues such as cell phenotype and growth factor signaling; structural cues such as extracellular matrix (ECM) deposition, ECM, and cell alignment; and mechanical cues such as compression, tension, shear, and the stiffness of the cellular microenvironment. In this review, we explore new discoveries in the field of interfacial biology related to ECM remodeling, cellular metabolism, and fate. Based on emergent findings across multiple disciplines, we lay out a framework for future innovations in the design of engineered strategies for interface regeneration. Many of the key mechanisms essential for interfacial tissue development and adaptation have high potential for improving outcomes in the clinic.
