Expression profiling of murine acute promyelocytic leukemia cells reveals multiple model-dependent progression signatures.

abstract：:The major cytoskeletal actin gene of Drosophila melanogaster, the actin 5C gene, has two promoters, the distal one of which controls synthesis of actin in a tissue- and developmental stage-specific manner. This very strong promoter has widely been used for expression of heterologous genes in cultured cells. To locate ...
