hF-LANa, a human homologue of Derlin family, regulating the expression of cancer-related genes promotes NIH3T3 cell transformation

hF-LANa, a member of Derlin family, is a putative proto-oncogene and has a direct role in oncogenic transformation. hF-LANa over-expressed NIH3T3 cells grow 20% quicker than parent cells. Especially, hF-LANa over-expression promotes anchorage-independent growth of NIH3T3 cells in soft agar and tumorigenesis in nude mice. Analysis by cDNA microarray finds 252 up-regulated genes and 354 down-regulated genes in hF-LANa over-expressed NIH3T3 cells including 19 oncogenes/proto-oncogenes and 13 tumor suppressor genes/putative tumor suppressors. These experiments show the oncogenic transformation role of hF-LANa both in vitro and in vivo, and highlight the genes that might be related to hF-LANa’s oncogenic effects.
