Juliane Winkler
Postdoctoral Fellow





Juliane studied Pharmacy at the University of Leipzig and received her Ph.D. at the University of Heidelberg. In her Ph.D. work, she focused on the influence of nuclear transport mechanisms on the development and progression of hepatocellular carcinoma (HCC). Eukaryotic cells fundamentally rely on a selective and highly efficient nucleocytoplasmic transport system. In a cancer cell almost all cellular processes and signaling cascades are dependent on a nuclear transport for maintaining their malignant phenotype. Juliane found, that a special nuclear transport cycle, CAS/importin-α1, is highly deregulated in HCC and required to maintain an aggressive phenotype in vitro and in vivo. In her current postdoc project Juliane is interested in the role of the nucleocytoplasmic transport machinery on metastasis development of breast cancer.
