A case of synchronous bilateral breast cancer with different pathological responses to neoadjuvant chemotherapy with different biological character

We report a case of synchronous locally advanced bilateral breast cancer with different pathological responses to neoadjuvant chemotherapy with different biological character. The patient had presented bilateral breast cancer: the left breast cancer was hormone receptor negative, human epidermal growth factor receptor-2 (HER2) positive, and classified as T4bN1M0, stage IIIb, while the right was hormone receptor positive, HER2-negative, and classified as T4bN0M0, stage IIIb. We administered four cycles of anthracycline-based therapy followed by 12 weekly cycles of taxane with trastuzumab for neoadjuvant chemotherapy. We had achieved a significant left tumor reduction after each chemotherapy, but not right tumor. Bilateral modified radical mastectomies with axillary lymph-node dissection were performed. The therapeutic effect in the left was determined as a pathological complete response, in contrast to the right side. She has no recurrence for more than five years, though she had advanced cancer with oncologic emergency. This case could be an informative experience to understand the relation of tumor biology and response to systemic therapy

Mis16 and Mis18 Are Required for CENP-A Loading and Histone Deacetylation at Centromeres

AbstractCentromeres contain specialized chromatin that includes the centromere-specific histone H3 variant, spCENP-A/Cnp1. Here we report identification of five fission yeast centromere proteins, Mis14–18. Mis14 is recruited to kinetochores independently of CENP-A, and, conversely, CENP-A does not require Mis14 to associate with centromeres. In contrast, Mis15, Mis16 (strong similarity with human RbAp48 and RbAp46), Mis17, and Mis18 are all part of the CENP-A recruitment pathway. Mis15 and Mis17 form an evolutionarily conserved complex that also includes Mis6. Mis16 and Mis18 form a complex and maintain the deacetylated state of histones specifically in the central core of centromeres. Mis16 and Mis18 are the most upstream factors in kinetochore assembly as they can associate with kinetochores in all kinetochore mutants except for mis18 and mis16, respectively. RNAi knockdown in human cells shows that Mis16 function is conserved as RbAp48 and RbAp46 are both required for localization of human CENP-A
