Abstract

We have previously identified 67 exons on a yeast artificial chromosome contig spanning 1.5 Mb around the multidrug resistance 1 gene region of human chromosome 7q21.1. In this study, we identified three novel cytoplasmic variants (MDC2-γ, MDC2-δ, and MDC2-ε) of the human metalloprotease-like disintegrin-like cysteine-rich protein 2 (MDC2) among these exons by screening a human brain cDNA library and also by using a reverse transcription polymerase chain reaction. Genomic sequence analysis strongly supported the idea that the variations in the cytoplasmic domain were generated by alternative splicing. The expression of MDC2 variant forms in human brain tissue and gliomas was examined by reverse transcription polymerase chain reaction and RNase protection assay. MDC2-ε was expressed only in the cortical and hippocampal regions in human brain, but not in gliomas. In contrast, MDC2-γ was a major form expressed in human gliomas. Specific expression of these cytoplasmic variants of MDC2 in human brain and its malignancies is discussed.
