  1. 1. Molecular characterization of estrogen receptor beta variants : cancer cell proliferation and invasion

    Författare :Li Xu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Estrogen plays crucial roles in the pathogenesis of breast cancer. Most of the known effects of estrogen signaling are mediated by estrogen receptors (ERs), ERα and ERβ. ERα is explored for breast cancer molecular classification and is a target of endocrine therapy. LÄS MER

  3. 2. Digital Dispersion Equalization and Carrier Phase Estimation in 112-Gbit/s Coherent Optical Fiber Transmission System
