Eggehard Holler, PhD
The research of Eggehard Holler, PhD, focuses on design, synthesis and characterization of novel nanoscale drug delivery systems based on polymalic acid. These "nano drugs" are single macromolecules, which are applicable in personalized medicine especially cancer treatment. They provide targeting of tumor markers and an array of prodrugs which are activated at the site of targeted cells in resonse of specific cellular stimuli. The nanomedicine was established in preclinical models of solid breast and brain tumors and for brain metastases and is prepared for translation into clinics. After appropriate modifications, the nanomaterial was transformed into reagents for differential diagnosis by MRI of solid and metastatic brain tumors. Research grants: NIH/NCI R01 CA123495; NIH/NCI R01 CA136841; NIH/NCI, U01 CA151815; The Martz Translational Breast Cancer Research Fund. In addition, grants by PB/SCAQMD; BTAP007 AQMD on traffic air pollution, such as heavy metals acquired by breathing and activation of signal pathways that might lead to brain malignancies.
