Abstract

Specificity protein (Sp) transcription factors regulate the expression of genes associated with several cellular processes and play a critical role in early development. Typically, Sp protein expression decreases with age in healthy adults. Research has shown that Sp proteins can impact the development and transformation of cancer cells and other oncogenic processes, including survival, proliferation, spread, and metastasis. Among the Sp proteins, Sp1, Sp3, and Sp4 have been the main targets of study as they are shown to be highly expressed in cancer cells compared to healthy cells. Increased levels of Sp1 are correlated with poor prognosis in some malignancies, including gastrointestinal cancers. In this review, we discuss the role of Sp transcription factors and examine their activities as pro-oncogenic factors in esophageal cancer (EC). Other aspects presented in this review are potential therapeutic options for EC that target Sp1. We summarize the published information on preclinical results using mithramycin and tolfenamic acid.
