Abstract:Background. ADAMS (a desintegrin and metalloprotease) are transmembrane multifunctional glycoproteins, involved in cell growth, differentiation, motility, cell signaling and respectively, tumor growth, progression and spread. Our aim was to evaluate ADAM17 gene expression in homogenous, laser-capture microdissected breast cancers and to correlate their level of expression with cancers clinical and pathological characteristics. Materials and Methods. Expression of ADAM17 was analyzed using quantitative reverse-transcription polymerase chain reaction in laser-capture microdissected breast cancers specimens and corresponding non-neoplastic breast tissues from 38 patients. Results. We measured significantly elevated amounts of ADAM17 transcripts in malignant breast cells compared with normal adjacent breast tissue. Increased expression of ADAM17 showed high-grade cancers (p=0.04), but any significant differences were found related to age, stage, histology, tumor size, nodal, and ER/PR status; although not statistically significant, increased ADAM17 expressions showed HER2/neu positive, highly proliferative (high Ki67) and metastasized cancers. Conclusions. Our study provides further evidence of ADAM17 up-regulations in breast cancers and confers further motivation for future work on development of ADAM-selective inhibitors for cancers treatment.
