    NF-κB Perturbation Reveals Unique Immunomodulatory Functions in Prx1+ Fibroblasts That Promote Development of Atopic Dermatitis

    Investigators examined human atopic dermatitis (AD) skin samples and found that human AD fibroblasts also overexpressed C-C motif chemokine ligand 11 (CCL11) and that perturbation of Ikkb–NF-κB in primary human dermal fibroblasts up-regulated CCL11.

    Angiogenic and Molecular Diversity Determine Hepatic Melanoma Metastasis and Response to Anti-Angiogenic Treatment

    Hepatic metastases was induced by intrasplenic injection of five different murine melanoma cell lines. The efficiencies of hepatic colonization, morphologic patterns, gene expression profiles and degree of vascularization were analyzed and Sorafenib was applied as anti-angiogenic treatment.
