Alternative Splicing: A Critical Regulator in Human Bone Biology and Tumor Progression

Area of Science:

• Molecular Biology
• Genetics
• Biochemistry

Background:

• Alternative splicing (AS) is a key transcriptional regulation mechanism generating protein diversity.
• AS influences cellular functions, tissue differentiation, organ development, and disease progression.
• AS plays critical roles in bone biology, affecting skeletal development, maintenance, and disease.

Purpose of the Study:

• To review the pivotal roles of AS in bone biology, including its effects on bone cells and remodeling.
• To highlight AS involvement in bone-related tumors and bone metastases.
• To explore AS mechanisms in various bone pathologies and their therapeutic potential.

Main Methods:

• Literature review focusing on AS in bone biology and disease.
• Analysis of AS regulatory effects on osteoblasts, osteoclasts, and chondrocytes.
• Examination of AS in bone tumors, metastases, and conditions like osteoporosis and osteoarthritis.

Main Results:

• AS significantly regulates osteoblasts, osteoclasts, chondrocytes, and bone remodeling.
• Bone-specific AS events are crucial for skeletal development and maintenance.
• Aberrant AS is implicated in osteosarcoma, Ewing sarcoma, chondrosarcoma, and bone metastases.

Conclusions:

• AS factors, signaling pathways, and mechanical cues collaboratively regulate bone cells.
• Targeting AS offers potential diagnostic and therapeutic strategies for bone diseases.
• Understanding AS mechanisms provides insights into clinical translational potential for bone disorders.
