Another pair of primers (F16/R17) was also designed encompassing exons 16 and 17 of the BMX open reading frame to detect all BMX isoforms including BMXΔN. Using F16/R17 primers to observe the levels of BMX mRNA in lung adenocarcinomas and adjacent non-tumour specimens by quantitative PCR, we found that there were no significant differences in expression. Here, BMX is linked to lung adenocarcinoma.
