Oral squamous cell carcinoma: Key clinical questions, biomarker discovery, and the role of proteomics

摘要

Background: The molecular and cellular mechanisms underlying the pathogenesis of oral squamous cell carcinoma (OSCC) are relatively poorly understood and remain a subject of significant importance. However, it is well established that OSCC is associated with a variety of risk factors and notably, the high incidence rates of OSCC found in developing countries are attributable to exposure to different forms of smokeless tobacco. Despite this, the way these factors contribute to the disease pathogenesis and, in particular, the transformation from oral premalignant lesions (OPLs) to primary tumor remains unknown. Recent developments in 'omics' technologies hold promise for deciphering these mechanisms through the discovery of key molecular and cellular regulatory pathways which are involved in disease progression.
