Figure 4

Reverse transcription-coupled PCR analysis of the relative proportion of KTS and exon 5 splice variants in normal versus cancerous breast tissue. (A) KTS variants. Bars: solid, plus forms; hatched, minus forms. (Total number of PCRs: normal, n = 31; tumor, n = 17). Normal tissue samples (n = 10) consisted of tissue from eight reduction mammoplasty patients and two samples of normal breast tissue in the vicinity of tumors. As a group and based on age (ranging from 23 to 45 years), these noncancer patients were considered premenopausal with the possible exception of one individual (52 years). Six tumor samples were analyzed. Data are the mean ± SD. (B) Exon 5 variants. Bars: solid, plus forms; hatched, minus forms. (Total number of PCRs: normal, n = 26; tumor, n = 15.)
