pubmed:abstractText |
The LAMB1 gene encodes the laminin beta1 subunit of laminin, an extracellular matrix protein. Using several transgenic mouse lines containing various lengths of the LAMB1 promoter driving lacZ reporter gene expression, regions of LAMB1 promoter that contain cis-acting DNA regulatory element(s) have been identified. The 3.9LAMB1betagal transgene is expressed in various tissues during development. LAMB1 transgene expression is observed in a selective set of nephrons of the neonatal and adult kidneys. The cis-acting DNA regulatory elements responsible for LAMB1 transgene expression in ovaries and in juvenile kidneys are present between -'1.4 and -0.7 kb relative to the transcription start site, while those of adult kidneys are located between -2.5 and -1.4 kb. The LAMB1 transgene is also expressed in the epididymis of 1 week old transgenic mice. Mutation of the retinoic acid response element (RARE) in the context of the 3.9LAMB1betagal transgene results in loss of LAMB1 transgene expression in all tissues. Thus, sequences between -2.5 and -0.7 kb plus the RARE are required for appropriate expression of the LAMB1 transgene in mice.
