Objective:
Adhesion regulating molecule-1 (ADRM1), a 26S proteasome adaptor protein, plays a crucial role in mediating the growth and differentiation of osteoclasts in osteoporosis (OP). However, its involvement in this osteoanabolic effect remains largely uninvestigated.
Methods:
In vitro experiments, including both gain-of-function and loss-of-function approaches, were conducted in MC3T3-E1 and C3H10T1/2 cells.
Results:
Knockdown of ADRM1 markedly promoted the growth of C3H10T1/2 cells while inhibiting apoptosis. Additionally, this intervention enhanced the expression of osteoblast differentiation markers and key proteins associated with the Wnt/β-catenin pathway. Notably, silencing ADRM1 promoted osteoblast mineralization and differentiation, as evidenced by increased Alizarin red staining and alkaline phosphatase staining. Conversely, MC3T3-E1 cells overexpressing ADRM1 exhibited results that were diametrically opposed to those observed with ADRM1 knockdown. Furthermore, treatment with ICG-001 (a Wnt/β-catenin pathway antagonist) reversed the effects of ADRM1 knockdown in C3H10T1/2 cells.
Conclusions:
Our findings suggest that silencing ADRM1 induces osteoblast mineralization and differentiation by activating the Wnt/β-catenin pathway. This finding underscores the therapeutic potential of the ADRM1/Wnt/β-catenin axis in treating OP.

01:29Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...
