During normal development, SALL4 expression decreases and becomes absent in most adult tissues, yet it is reactivated in many human cancers. Dysregulated SALL4 supports proliferation, apoptosis, metastasis, and drug resistance, acting as either epigenetic activator or repressor. It also coordinates downstream gene expression and key signaling pathways, making SALL4 a diagnostic and prognostic biomarker and therapeutic target.

SALL4 expression gradually decreases during development and is even absent in most adult tissues. However, increasing evidence suggests that SALL4 expression is restored in human cancersand its aberrant expression is associated with the progression of many hematopoietic malignancies and solid tumors. The potent roles of SALL4 in regulating cancer cell proliferation, apoptosis, metastasis, and drug resistance have been reported. SALL4 plays a dual role in epigenetic modulation by acting as either an activator or a repressor of its target genes. Furthermore, SALL4 interacts with other partners to control the expression of many downstream genes and the activation of various key signaling transduction pathways. SALL4 is considered as a promising diagnostic and prognostic biomarker and therapeutic target for cancer. In this review, we highlighted the major advances in the roles and mechanisms of SALL4 in cancer and the therapeutic strategies for targeting SALL4 to treat cancer.  \nK E Y WO R D S  \nbiomarker, cancer, miRNA, SALL4, therapeutic target  \nThis is an open access article under the terms of the Creative Commons Attribution-NonCommercial License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited and is not used for commercial purposes.  \n© 2023 The Authors.
