Itga10, or integrin subunit alpha10, is an integrin that plays crucial roles in various biological processes. It is involved in the activation of the PI3K/AKT pathway [1,2,5]. This integrin is important for processes such as cell adhesion, migration, and differentiation, and is also associated with the extracellular matrix [4]. Genetic models can be valuable in studying its functions and implications in disease.

In osteosarcoma, knockdown of ZIP10, which promotes ITGA10 transcription and ITGA10-mediated PI3K/AKT pathway activation, suppressed cell proliferation and chemoresistance, indicating ITGA10's role in driving these processes in the disease [1]. In osteoblasts, miR-4739 inhibitor promoted cell proliferation, differentiation, and inhibited apoptosis by increasing ITGA10 expression and activating the PI3K/AKT pathway, suggesting ITGA10's importance in osteoblast function [2]. In alveolar bone marrow mesenchymal stem cells from type 2 diabetic patients, ITGA10 knockdown reduced adhesion, migration, and osteogenic differentiation by disturbing the FAK/PI3K/AKT/GSK3β/β-catenin pathway [5].

In conclusion, Itga10 is essential for functions like cell adhesion, migration, and differentiation, with its dysregulation contributing to diseases such as osteosarcoma, osteoporosis, and affecting osseointegration in type 2 diabetes. Studies using gene-knockdown models have been instrumental in revealing its role in these disease-related biological processes, providing potential therapeutic targets for treatment [1,2,5].
