Promoter Methylation Status of Breast Cancer Susceptibility Gene 1 and 17 Beta Hydroxysteroid Dehydrogenase Type 1 Gene in Sporadic Breast Cancer Patients

<div>A representative gel picture of ethidium bromide-stained 2% agarose gel showing<i> 17<i>β</i>HSD-1</i> methylation status of two cases. Lane 1: a 100 bp DNA ladder. Lanes 2, 3, 4, 5, 6, 7, 8, and 9: the presence of (238 bp) band indicates methylation of<i> 17<i>β</i>HSD-1</i> promoter in these specimens. Lane 10: negative control. Lanes 2 and 6: undigested DNA of normal breast tissue specimens; lanes 3 and 7: digested DNA of normal breast tissue specimens; lanes 4 and 8: undigested DNA of cancerous breast tissue specimens; and lanes 5 and 9: digested DNA of cancerous breast tissue specimens.</div>
