AI Article Synopsis
- BONJ is a complication from bisphosphonate treatment that's not well understood, and its treatment relies mainly on expert advice rather than solid guidelines.
- Three patients on long-term bisphosphonate therapy showed signs of BONJ, and surgical resection of the affected bone was performed, with histologic analysis done on the specimens.
- The analysis revealed both necrotic bone and signs of underlying malignancy, suggesting that histologic confirmation is essential for diagnosing BONJ in patients with cancer.
Article Abstract
Objective: Bisphosphonate-related osteonecrosis of the jaw (BONJ) is a common complication of bisphosphonate treatment that has been well documented over the past decade. Nevertheless, its pathogenesis is poorly understood, and treatment guidelines are based mostly on expert recommendations. Clinicians must be aware of malignancy mimicking BONJ, of which a few cases have been documented in the literature.
Study Design: Three patients undergoing long-term treatment with intravenous bisphosphonates for malignant disease demonstrated the distinct diagnostic signs of BONJ. Surgical treatment was performed by resecting the affected bone. In all cases, histologic specimens were taken for analysis.
Results: Histologic analysis of the bone specimen with surrounding soft tissue revealed necrotic bone with signs of inflammation, but also with cells of the underlying malignant disease.
Conclusions: Clinical and radiographic diagnosis of BONJ should be confirmed by histologic analysis in patients with underlying malignant disease.

Delivering plasmid DNA (pDNA) to solid tumors remains a significant challenge due to the requirement for multiple transport steps and the need to promote delivery efficiency. Herein, we present a virus-mimicking hybrid lipoplex, composed of an arginine-rich cationic lipid, hyaluronic acid derivatives coated gold nanoparticles, and pDNA. This system induces cytoskeletal rearrangements through "outside-in" mechanical and "inside-out" biochemical signaling, overcoming intra- and intercellular barriers to enhance pDNA delivery.

Background: Primary luminal breast cancer cells lose their identity rapidly in standard tissue culture, which is problematic for testing hormone interventions and molecular pathways specific to the luminal subtype. Breast cancer organoids are thought to retain tumor characteristics better, but long-term viability of luminal-subtype cases is a persistent challenge. Our goal was to adapt short-term organoids of luminal breast cancer for parallel testing of genetic and pharmacologic perturbations.
