    Proteolytic activities in the extracellular matrix by the matrix metalloproteinase (MMP)-14 have been implicated in the remodeling of collagenous proteins during development. To analyze the function of fibroblast-derived MMP-14 in adult skin homeostasis, we generated mice with inducible deletion...
  2. Complete lymph node dissection versus no dissection in patients with sentinel lymph node biopsy positive melanoma (DeCOG-SLT): a multicentre, randomised, phase 3 trial.

    The Lancet Oncology 17(6):757 (2016) PMID 27161539

    Complete lymph node dissection is recommended in patients with positive sentinel lymph node biopsy results. To date, the effect of complete lymph node dissection on prognosis is controversial. In the DeCOG-SLT trial, we assessed whether complete lymph node dissection resulted in increased surviv...
  3. Oncogene and therapeutic target analyses in atypical fibroxanthomas and pleomorphic dermal sarcomas.

    Oncotarget 7(16):21763 (2016) PMID 26943575

    Until now, almost nothing is known about the tumorigenesis of atypical fibroxanthoma (AFX) and pleomorphic dermal sarcoma (PDS). Our hypothesis is that AFX is the non-infiltrating precursor lesion of PDS. We performed the world-wide most comprehensive immunohistochemical and mutational analysis ...

    Expert Review of Molecular Diagnostics 16(4):423 (2016) PMID 26822148

    Melanoma is one of the clinically most important cancer types considering its high mortality rate and that it is commonly diagnosed in relatively young people. With the advent of targeted therapies and, more recently, immune checkpoint inhibitors, more treatment options are available resulting i...

    Melanoma Research 25(6):503 (2015) PMID 26352784

    Mucosal melanoma of the head and neck is a rare and aggressive tumor entity with a poor prognosis. The standard treatment is radical tumor resection, with or without adjuvant radiation, where conventional chemotherapies in advanced stage or recurrent diseases have shown little benefit. Overexpre...

    Cell 162(1):146 (2015) PMID 26140595

    KRAS is one of the most frequently mutated oncogenes in human cancer. Despite substantial efforts, no clinically applicable strategy has yet been developed to effectively treat KRAS-mutant tumors. Here, we perform a cell-line-based screen and identify strong synergistic interactions between cell...
  10. IAP antagonization promotes inflammatory destruction of vascular endothelium.

    EMBO Reports 16(6):719 (2015) PMID 25825408 PMCID PMC4467856

    In this study, we show for the first time that the therapeutic antagonization of inhibitor of apoptosis proteins (IAPs) inhibits B16 melanoma growth by disrupting tumor vasculature. Specifically, the treatment of mice bearing B16 melanoma with an IAP antagonist compound A (Comp A) inhibits tumor...
  11. Enhanced FHL2 and TGF-β1 Expression Is Associated With Invasive Growth and Poor Survival in Malignant Melanomas.

    American Journal of Clinical Pathology 143(2):248 (2015) PMID 25596251

    This study examines the expression and the role of four-and-a-half LIM domains protein 2 (FHL2) and transforming growth factor β1 (TGF-β1) in human malignant melanoma. It is determined whether both proteins influence melanoma survival time. We analyzed the immunohistochemical staining intensitie...
  12. TGF-β1-dependent induction and nuclear translocation of FHL2 promotes keratin expression in pilomatricoma.

    Virchows Archiv. A. Pathological Anatomy and Hi... 466(2):199 (2015) PMID 25477051

    Pilomatricoma is a tumour derived from hair matrix cells, which shows progressive keratin expression. Tumorigenesis is frequently associated with activating mutations in β-catenin gene inducing nuclear expression of β-catenin protein. The present study analysed the role of transforming growth fa...
  13. Nivolumab in previously untreated melanoma without BRAF mutation.

    New England Journal of Medicine 372(4):320 (2015) PMID 25399552

    Nivolumab was associated with higher rates of objective response than chemotherapy in a phase 3 study involving patients with ipilimumab-refractory metastatic melanoma. The use of nivolumab in previously untreated patients with advanced melanoma has not been tested in a phase 3 controlled study....
  14. Matrix metalloproteinase 14 is required for fibrous tissue expansion.

    eLife 4:e09345 (2015) PMID 26390284 PMCID PMC4684142

    Type I collagen-containing fibrils are major structural components of the extracellular matrix of vertebrate tissues, especially tendon, but how they are formed is not fully understood. MMP14 is a potent pericellular collagenase that can cleave type I collagen in vitro. In this study, we show th...
