Molecular Crosstalk Between RUNX2 and HIF-1α in Osteosarcoma: Implications for Angiogenesis, Metastasis, and Therapy Resistance.

Runt-related transcription factor-2 (RUNX2) is an integral player in osteogenesis and is highly expressed in osteosarcoma. Emerging evidence suggests that aberrant RUNX2 expression is a key factor in osteosarcoma oncogenesis. Patients with advanced stages of osteosarcoma overexpressing RUNX2 are more likely to have high tumour grades, metastasis, and lower overall or progression-free survival rates.

Systemic strategies for osteosarcoma: advances and future directions.

Osteosarcoma is a common and aggressive bone cancer in children and adolescents, typically affecting the long bones during growth spurts. Treatment involves a combination of surgery, chemotherapy, and radiotherapy. Although surgery has become more limb-preserving, the overall prognosis remains challenging, with a 5-year survival rate of 60-70% for localized disease and much lower for advanced stages.

Molecular crosstalk in SP7-mediated osteogenesis: Regulatory mechanisms and therapeutic potential.

SP7, also known as Osterix, is a zinc finger-containing transcription factor, plays a crucial role in osteoblast differentiation and bone formation. This review examines the molecular mechanisms underlying SP7's regulatory functions, highlighting its interactions with key signaling pathways such as BMP-SMAD, Wnt/β-catenin, and HIF-1α. SP7 acts downstream of RUNX2 to regulate osteogenic gene expression, including collagen Type I Alpha 1 (COL1A1), alkaline phosphatase (ALP) and osteocalcin (OCN).

Potentials of SGLT2 inhibitors in the treatment of diabetic rotator cuff diseases: a comprehensive review.

Degenerative rotator cuff disease (RCD) is a common musculoskeletal condition that disproportionately affects individuals with diabetes mellitus, leading to pain, functional impairment, and a reduced quality of life. Emerging evidence suggests that sodium-glucose co-transporter 2 inhibitors (SGLT2is), which are widely used for glycemic control in type 2 diabetes, offer additional musculoskeletal benefits beyond their metabolic effects. This review explores the potential protective role of SGLT2is in diabetic RCD by examining the epidemiological link between diabetes and tendon degeneration and evaluating the biological mechanisms through which SGLT2 is influence tendon health.

A Narrative Review on the Double Pulley-Triple Row Technique for Large to Massive Rotator Cuff Repair.

Rotator cuff tears are common shoulder injuries that often necessitate surgical intervention, particularly when nonoperative treatments fail. Arthroscopic rotator cuff repair is the current gold standard; however, challenges, such as high retear rates, especially in large tears, persist. Traditional techniques, such as single-row and double-row repairs, have limitations in fully restoring the anatomical footprint and ensuring optimal healing.

Synergistic HDAC4/8 Inhibition Sensitizes Osteosarcoma to Doxorubicin via pAKT/RUNX2 Pathway Modulation.

Osteosarcoma is a highly aggressive bone malignancy, particularly challenging in metastatic cases, with a 5-year survival rate remaining under 30%. Although doxorubicin (doxo) is a standard first-line chemotherapeutic agent, its clinical utility is often hindered by the development of drug resistance and associated systemic toxicity. Emerging evidence highlights the role of epigenetic alterations, particularly those involving histone deacetylases (HDACs), in promoting chemoresistance.

Arthroscopic-guided Release of Supraspinatus and Infraspinatus Muscles for Repair of Large-to-Massive Rotator Cuff Tear and Suprascapular Nerve Release.

This technical note presents an all-arthroscopic technique designed to release and advance the supraspinatus and infraspinatus muscles in cases of massive posterosuperior rotator cuff tears involving the retracted muscles. The aim is to avoid neuromuscular damage and facilitate tension-free repair by reducing the anatomical tendon footprint. Traditionally, such tears have been considered irreparable and have been treated with superior capsular reconstruction or tendon-transfer procedures.

Revolutionizing oncology: the role of Artificial Intelligence (AI) as an antibody design, and optimization tools.

Antibodies play a crucial role in defending the human body against diseases, including life-threatening conditions like cancer. They mediate immune responses against foreign antigens and, in some cases, self-antigens. Over time, antibody-based technologies have evolved from monoclonal antibodies (mAbs) to chimeric antigen receptor T cells (CAR-T cells), significantly impacting biotechnology, diagnostics, and therapeutics.

Double Pulley-Triple Row Technique for Arthroscopic Rotator Cuff Repair: A Technical Note.

Arthroscopic rotator cuff repair is the gold standard for treatment, but current techniques have shortcomings, especially for larger tears. Single-row repairs often fail to fully restore the footprint, leading to high retear rates. Although triple-row and double-row repairs show promise, concerns regarding retear persist.

Advancements in Therapeutic Approaches for Degenerative Tendinopathy: Evaluating Efficacy and Challenges.

Degenerative tendinopathy results from the accumulation of minor injuries following unsuccessful tendon repair during acute tendon injuries. The process of tendon repair is prolonged and varies between individuals, making it susceptible to reinjury. Moreover, treating chronic tendinopathy often requires expensive and extensive rehabilitation, along with a variety of combined therapies to facilitate recovery.

Application of ChatGPT for Orthopedic Surgeries and Patient Care.

Artificial intelligence (AI) has rapidly transformed various aspects of life, and the launch of the chatbot "ChatGPT" by OpenAI in November 2022 has garnered significant attention and user appreciation.
