Effects of macrophages in OSCC progression.
Front Immunol

Department of Oral Anatomy and Physiology, Jilin Provincial Key Laboratory of Oral Biomedical Engineering, Hospital of Stomatology, Jilin University, Changchun, China.
Macrophages are crucial immune cells within the tumor microenvironment (TME), involved in regulating tumor proliferation, invasion, metastasis, ECM remodeling, angiogenesis, and immunosuppression. Although more and more experimental evidence and clinical data indicate that macrophages are involved in the onset and progression of oral squamous cell carcinoma (OSCC), the exact pathogenesis of OSCC associated with macrophages has not been fully elucidated. Enhanced knowledge of the molecular mechanisms involving macrophages in OSCC will aid in the creation of treatments targeted specifically at macrophages.

Molecular Carcinogenesis Program, Coordination of Research and Innovation, Brazilian Nacional Cancer Institute (INCA), Rio de Janeiro, Brazil.
Background: The advanced stage of cancer is a determining factor in poor prognosis. Head and neck squamous cell carcinomas (HNSCC) are highly incident in Brazil, but similarly to many Low and Middle-Income Countries, data is limited regarding the proportion of tumours diagnosed at advanced clinical stages and the main factors associated with it. Therefore, this study aimed to identify the factors associated with advanced stage of HNSCC in Brazil.

Odontogenic keratocyst (OKC) and ameloblastoma (AM) are common jaw lesions with high bone-destructive potential and recurrence rates. Recent advancements in technology led to significant progress in understanding these conditions. Single-cell and spatial omics have improved insights into the tumor microenvironment and cellular heterogeneity in OKC and AM.

Hospital of Stomatology, Sun Yat-Sen University, Guangzhou, China.
Emerging evidence shows that lipid metabolic reprogramming plays a vital role in tumor metastasis. The effect and mechanism of fatty acids and lipid droplets (LDs), the core products of lipid metabolism, on the metastasis of oral squamous cell carcinoma (OSCC), need further exploration. In this study, the influence of palmitic acid (PA) and oleic acid (OA) on the migration and invasion ability of OSCC cells was determined by in vitro experiments.
