Giant cell tumor of bone (GCTB) is a rare osteolytic tumor composed of mononuclear stromal cells, macrophages, and osteoclast-like giant cells. While generally benign, GCTB has a high risk of local recurrence and can occasionally undergo malignant transformation or metastasis, posing significant clinical challenges. The primary treatment is complete surgical resection; however, effective management strategies for recurrent or advanced GCTB remain elusive, underscoring the need for further preclinical research.

Islet amyloid polypeptide (IAPP) fibrillation induces β-cell dysfunction and toxicity in patients with type 2 diabetes. Cytotoxicity is caused by the ability of IAPP fibrils and fibrillar intermediates to permeate the cellular membrane of pancreatic β-cells, trigger endoplasmic reticular stress, induce reactive oxygen species production, and upregulate apoptosis-related genes. Thus, inhibition of IAPP fibrillation is of great interest for preventing associated cytotoxicity.

Galectin-3 is an endogenous lectin which binds mainly to β-galactosides on the cell surface and extracellular matrix (ECM) glycoproteins. In the thymus, this lectin is constitutively expressed, being involved in thymocyte adhesion, migration, and death. Galectin-3 has been related to type 1 diabetes, an autoimmune disease characterized by pancreatic β-cell destruction mediated by autoreactive T lymphocytes.
