Abstract excerpt
Our previous results describing the CH12.LX (AhR-expressing) and BCL-1 (AhR-deficient) B cell lines have supported an AhR/dioxin-responsive element (DRE)-mediated mechanism for TCDD-induced inhibition of micro heavy chain expression and thus of IgM secretion. Transcriptional regulation of the Ig heavy chain genes involves several regulatory elements including the 3'alpha Ig heavy chain enhancer, which is composed...
