BRCA1 promoter hypermethylation in human placenta: a hidden link with β-hCG expression.

abstract：:The breast cancer gene BRCA1 has previously been cloned from both human and mouse. We cloned a fragment of the rat Brca1 homologue in order to map it and explore its biological function. Partial cDNA fragments of the rat Brca1 homologue were isolated by RT-PCR. Sequence analysis revealed that the RING-finger domain is...
