These findings suggest that the transcription of the b4GalT3 gene is regulated by differential DNA binding of Sp3 and Sp1 in neuroblastoma and lung cancer. The increased expression of b4GalT3 in neuroblastoma may be ascribed to the enhanced expression of Sp3, which is observed for various cancers.
The increase in the number of cell passages is associated with a decrease in their ability to proliferate until senescence is reached. This process is likely to be mediated by the altered expression of nuclear-located transcription factors such as Sp1 and NFI, whose expression has been documented to be required for cell adhesion, migration, and differentiation.
after Sp1 expression was significantly suppressed by RNA interference, LfR was significantly decreased at both RNA and protein levels. In conclusion, the LfR gene promoter contains downstream core promoter elements, and the Sp1 binding sites play critical roles in transcriptional regulation of the LfR gene.

Sp1 or HDAC1 knock down increased GM2-synthase transcription, and butyrate-mediated activation of GM2-synthase mRNA expression in SK-RC-45 cells was accompanied by Sp1 and HDAC1 loss from the +38/+187 region. Taken together, we have identified an epigenetic mechanism for the de-repression of the GM2-synthase gene in RCC.
These data demonstrate that miR-326/Sp1/KLF3 regulatory axis is involved in the development of lung cancer. miR-326 could bind to 3'UTR of Sp1 but not KLF3 and decreased the accumulation of Sp1, which further indirectly reduced KLF3 expression and inactivated JAK2/STAT3 and PI3K/AKT signaling pathways in vitro and in vivo.

The protein encoded by this gene is a zinc finger transcription factor that binds to GC-rich motifs of many promoters. The encoded protein is involved in many cellular processes, including cell differentiation, cell growth, apoptosis, immune responses, response to DNA damage, and chromatin remodeling. Post-translational modifications such as phosphorylation, acetylation, glycosylation, and proteolytic processing significantly affect the activity of this protein, which can be an activator or a repressor. Three transcript variants encoding different isoforms have been found for this gene.
