About 7.9-27.6% of oral dysplasia, a premalignant lesion, transit to the invasive oral cavity squamous cell carcinoma (OCSCC). Prognostic biomarkers are critically needed to determine patients with oral dysplastic lesions at risk for malignant transformation and to guide the targeted development of novel therapies. Our goal is to establish a single-cell atlas of premalignant immune microenvironment (PRIME) in oral dysplasia and to identify immune features that predict the malignant transformation to OCSCC. We propose an innovative approach that combines high-dimensional imaging mass cytometry (IMC) and machine learning predictive modeling (iEN) to analyze a total of ~200 Formalin-Fixed Paraffin-Embedded (FFPE) patient tongue biopsies from the Oral Pathology Archive at the University of the Pacific (UOP), Arthur A. Dugoni School of Dentistry. IMC is a new multiplex imaging technology which combines high- dimensional mass cytometry with microscopy. Immune Elastic Net (iEN) is a machine learning algorithm specifically developing for the analysis of high-dimensional mass cytometry data. We plan to identify immune features that differentiate oral dysplasia severity (Aim 1) and predict OCSCC malignant transformation (Aim 2). In addition, we will analyze the iEN-selected immune features at UOP Han’s lab by conducting multiplex immunofluorescence (mIF) staining on the whole sections (Aim 1&2) to validate and generalize the IMC findings. The proposed research will establish immune landscape in oral dysplasia and identify biomarkers to predict the malignant transformation. It also provides an opportunity for predental or dental students participating in translational research and collaborating with multidisciplinary team to identify biomarkers to improve oral pathology diagnosis.

约7.9-27.6%的口腔异型增生是一种癌前病变，向浸润性口腔鳞状细胞转化 癌（OCSCC）。迫切需要预后生物标志物来确定口腔癌患者 有恶变风险的发育异常病变，并指导靶向开发新的 治疗我们的目标是建立癌前免疫微环境（PRIME）的单细胞图谱 在口腔发育不良中的作用，并确定预测口腔鳞状细胞癌恶性转化的免疫特征。 我们提出了一种创新的方法，结合高维成像质量细胞术（IMC）， 机器学习预测建模（iEN），以分析总共约200个福尔马林固定石蜡包埋 （FFPE）来自太平洋大学（UOP）口腔病理学档案馆的患者舌活检， 亚瑟A.
