“This study aimed to elucidate the clinical implication of human epidermal growth factor receptor 2/centromeric probe for chromosome 17 (HER2/CEP17) ratio and HER2 immunohistochemistry (IHC) results in patients with HER2 fluorescence in situ hybridization GSK2879552 concentration (FISH)-positive metastatic breast cancer (MBC) who received first-line trastuzumab plus taxane chemotherapy.\n\nUsing clinical data of patients with HER2 FISH-positive MBC who received first-line trastuzumab plus taxane chemotherapy, we analyzed the clinical outcome according to the HER2/CEP17
ratio and HER2 IHC analysis.\n\nFifty-two women were analyzed. The median age was 50 years (range 27-69 years). Patients with a HER2/CEP17 ratio a parts per thousand yen3.0 had significantly longer progression-free survival (PFS) (17.2 vs. 7.4 months; p = 0.002) with a tendency toward higher response rate (RR) (p = 0.325) and longer overall survival (OS) (p = 0.129). Patients with HER2 IHC 1+ had significantly shorter OS (14.0 vs. 42.4 months; p = 0.013) along with a tendency toward lower RR (p = 0.068) and shorter PFS (p = 0.220). In the multivariate analysis, HER2/CEP17 ratio < 3.0 (p = 0.004) and Eastern Cooperative Oncology Group (ECOG) PS 2 (p = 0.015) were
significant factors for shorter LY411575 price PFS, Vorinostat in vivo and HER2 IHC 1+ (p = 0.015) and ECOG PS 2 (p = 0.036) were significant factors for poor OS.\n\nOur data support that HER2/CEP17 ratios and HER2 IHC scores may predict clinical outcome after first-line trastuzumab plus taxane chemotherapy in patients with HER2 FISH-positive MBC.”
“Ubiquitination plays a key role in protein degradation and signal transduction. Ubiquitin is a small protein modifier that is adducted to lysine residues by the combined function of E1, E2, and E3 enzymes and is removed by deubiquitinating enzymes. Characterization of ubiquitination sites is important for understanding the role of this modification in cellular processes and disease. However, until recently, large-scale characterization of endogenous ubiquitination sites has been hampered by the lack of efficient enrichment techniques. The introduction of antibodies that specifically recognize peptides with lysine residues that harbor a di-glycine remnant (K-epsilon-GG) following tryptic digestion has dramatically improved the ability to enrich and identify ubiquitination sites from cellular lysates. We used this enrichment technique to study the effects of proteasome inhibition by MG-132 and deubiquitinase inhibition by PR-619 on ubiquitination sites in human Jurkat cells by quantitative high performance mass spectrometry.
