Sp1 transcriptionally regulates BRK1 expression in non-small cell lung cancer cells.
Title: Sp1 transcriptionally regulates BRK1 expression in non-small cell lung cancer cells.
We verified that NRF-1 positively regulates FAM134C and ENOX1, and negatively regulates C3orf10 in human neuroblastoma IMR-32 cells and primary rat cortical neurons.
Title: Novel genes FAM134C, C3orf10 and ENOX1 are regulated by NRF-1 and differentially regulate neurite outgrowth in neuroblastoma cells and hippocampal neurons.
Data show that Brk1 downregulation results in defective directional migration and invasive growth in renal cell carcinoma cells as well as in other tumor cell types.
Title: Brick1 is an essential regulator of actin cytoskeleton required for embryonic development and cell transformation.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
