Up-regulation of some developmental genes has been observed in cancerous tissues and cancer cells. Sal-like 4 (SALL4), a member of the homologs of Dorosophila spalt (sal) gene, plays a key role in early development and organogenesis. SALL4 encodes a C2H2 multiple zinc finger protein, and is a causative gene for Okihiro/Duane radial ray syndrome, the major symptoms of which are limb malformation...

The aim of this study was to evaluate the effects of small interfering RNA (siRNA)-inhibited expression of the Sal-like 4 (SALL4) gene on the proliferation, colony formation, and apoptosis of prostate cancer C4-2 cells. C4-2 cells were cultured and divided into a si-SALL4 group, a negative control siRNA group, and a blank control group. SALL4 mRNA levels and protein expression were detected by ...

BACKGROUND Myelodysplastic syndromes (MDS) are a group of heterogeneous diseases with variable clinical course. Predicting disease progression is difficult due to lack of specific molecular marker(s). SALL4 plays important roles in normal hematopoiesis and leukemogenesis. SALL4 transgenic mice develop MDS prior to acute myeloid leukemia (AML) transformation. However, the role of SALL4 in human ...

Sall4 is an essential transcription factor for early mammalian development and is frequently overexpressed in cancer. Although it is reported to play an important role in embryonic stem cell (ESC) self-renewal, whether it is an essential pluripotency factor has been disputed. Here, we show that Sall4 is dispensable for mouse ESC pluripotency. Sall4 is an enhancer-binding protein that prevents p...

Spermatogonial stem cells (SSCs) maintain spermatogenesis throughout adulthood through balanced self-renewal and differentiation, yet the regulatory logic of these fate decisions is poorly understood. The transcription factors Sal-like 4 (SALL4) and promyelocytic leukemia zinc finger (PLZF; also known as ZBTB16) are known to be required for normal SSC function, but their targets are largely unk...

Genes required for limb developm ent have, in several instances, first been identified by studies of human diseases in which the limbs are affected. In humans, m utations in the transcription factor SALL4 results in Okihiro syndrome (OS), which is characterised by forelimb defects and the eye disorder, Duane anom aly. OS patients forelim b defects range from subtle thumb abnormalities to trunca...

Background Acute myeloblastic leukemia (AML) is a clonal disorder due to bone marrow failure and uncontrolled proliferation of myeloid lineage. Acute promyelocytic leukemia (APL) is a subtype of AML. Heterocyclic compounds, such as indole, are considered as attractive candidates for cancer therapy, due to their abundance in nature and known biological activity. Sal-like protein (SALL4) is a zin...

Few target molecules have been identified that enable the diagnosis of breast cancer with a high sensitivity and specificity, especially in the early clinical stages of cancer. Here, we present the first evidence for diagnostic performance of gene expression for SALL4, a transcription factor that plays an essential role in the embryonic development and self-renewal of embryonic stem (ES) cells,...

Human cancer cells resemble stem cells in expression signatures leading them to share some features, most notably, self-renewal. A complex network of transcription factors and signaling molecules are required for continuation of this trait. ZNF797 (SALL4) is a zinc finger transcriptional activator crucial for maintenance of self-renewal in stem cells; however, its expression level has not yet b...

Hematopoietic Stem Cells (HSCs) are cells that have the ability to self-renewal and differentiate into all of hematopoietic lineages. The lack of donors and unavailable efficient protocols for ex vivo expansion of HSCs, are obstacles in successful cell therapies. MicroRNAs (also refer as miRNAs or miRs) have significant roles in hematopoiesis; they can effect on HSCs expansion, maintaining undi...
