1. The pivotal role of reactivity in the design of novel biotinylation reagents for the chemical-proteomics-based identification of vascular accessible biomarkers.

    Journal of Proteomics 141:57 (2016) PMID 27113135

  2. Plasma S100P level as a novel prognostic marker of metastatic breast cancer.

    Breast Cancer Research and Treatment 157(2):329 (2016) PMID 27146585

    Metastasis is the main cause of death in breast cancer patients. The development of reliable and cost-effective biomarker to evaluate the prognosis of metastatic breast cancer (MBC) patients is of great importance. S100P is a member of S100 family and has been proved to be associated with metast...
  3. Plasma hyaluronic acid level as a prognostic and monitoring marker of metastatic breast cancer.

    International Journal of Cancer 138(10):2499 (2016) PMID 26686298

    Conventional tumor markers have limited value for prognostication and treatment monitoring in metastatic breast cancer (MBC) patients and novel circulating tumor markers therefore need to be explored. Hyaluronic acid (HA) is a major macropolysaccharide in the extracellular matrix and is reported...
  4. Circulating miRNAs with prognostic value in metastatic breast cancer and for early detection of metastasis.

    Carcinogenesis 37(5):461 (2016) PMID 26785733

    Metastasis is the principal cause of high morbidity and mortality among breast cancer (BC) patients. Identification of markers that can be routinely monitored to predict onset of metastasis in BC patients and prognosis of metastatic breast cancer (MBC) patients would increase their median surviv...
  5. CYP3A5 mediates basal and acquired therapy resistance in different subtypes of pancreatic ductal adenocarcinoma.

    Nature Medicine 22(3):278 (2016) PMID 26855150 PMCID PMC4780258

    Although subtypes of pancreatic ductal adenocarcinoma (PDAC) have been described, this malignancy is clinically still treated as a single disease. Here we present patient-derived models representing the full spectrum of previously identified quasi-mesenchymal (QM-PDA), classical and exocrine-lik...
  6. Ion source-dependent performance of 4-vinylpyridine, iodoacetamide, and N-maleoyl derivatives for the detection of cysteine-containing peptides in complex proteomics.

    Analytical and Bioanalytical Chemistry 408(8):2055 (2016) PMID 26493978

    Cysteine is unique among the proteinogenic amino acids due to its ability to form disulfide bonds. While this property is of vital importance for protein structures and biological processes, it causes difficulties for the mass spectrometric identification of cysteine-containing peptides. A commo...
  7. Myc Depletion Induces a Pluripotent Dormant State Mimicking Diapause.

    Cell 164(4):668 (2016) PMID 26871632 PMCID PMC4752822

    Mouse embryonic stem cells (ESCs) are maintained in a naive ground state of pluripotency in the presence of MEK and GSK3 inhibitors. Here, we show that ground-state ESCs express low Myc levels. Deletion of both c-myc and N-myc (dKO) or pharmacological inhibition of Myc activity strongly decrease...
  8. miR-126 Drives Quiescence and Self-Renewal in Leukemic Stem Cells.

    Cancer Cell 29(2):133 (2016) PMID 26859449

    Leukemic stem cells (LSCs) are resistant to conventional chemotherapy and promote acute myeloid leukemia (AML) progression and recurrence. In this issue of Cancer Cell, Lechman and colleagues (2016) identify the microRNA miR-126 as a regulator of PI3K-AKT-mTOR and CDK3 signaling driving LSC self...
  9. Convergence of cMyc and β-catenin on Tcf7l1 enables endoderm specification.

    EMBO Journal 35(3):356 (2016) PMID 26675138 PMCID PMC4741304

    The molecular machinery that directs formation of definitive endoderm from pluripotent stem cells is not well understood. Wnt/β-catenin and Nodal signalling have been implicated, but the requirements for lineage specification remain incompletely defined. Here, we demonstrate a potent effect of i...
  10. STEM CELLS. Potency finds its niches.

    Science 351(6269):126 (2016) PMID 26744396

  11. The influence of prostatic anatomy and neurotrophins on basal prostate epithelial progenitor cells.

    Prostate 76(1):114 (2016) PMID 26444457

    Based on findings of surface marker, protein screens as well as the postulated near-urethral location of the prostate stem cell niche, we were interested whether androgen ablation, distinct anatomic regions within the prostate or neurotrophins have an influence on basal prostate epithelial proge...
  12. Selection and dynamics of embryonic stem cell integration into early mouse embryos.

    Development 143(1):24 (2016) PMID 26586221 PMCID PMC4725202

    The process by which pluripotent cells incorporate into host embryos is of interest to investigate cell potency and cell fate decisions. Previous studies suggest that only a minority of the embryonic stem cell (ESC) inoculum contributes to the adult chimaera. How incoming cells are chosen for in...
  13. Transcriptional Heterogeneity and Lineage Commitment in Myeloid Progenitors.

    Cell 163(7):1663 (2015) PMID 26627738

    Within the bone marrow, stem cells differentiate and give rise to diverse blood cell types and functions. Currently, hematopoietic progenitors are defined using surface markers combined with functional assays that are not directly linked with in vivo differentiation potential or gene regulatory ...
  14. A novel autosomal recessive TERT T1129P mutation in a dyskeratosis congenita family leads to cellular senescence and loss of CD34+ hematopoietic stem cells not reversible by mTOR-inhibition.

    Aging (Albany, NY. Online) 7(11):911 (2015) PMID 26546739 PMCID PMC4694062

    The TERT gene encodes for the reverse transcriptase activity of the telomerase complex and mutations in TERT can lead to dysfunctional telomerase activity resulting in diseases such as dyskeratosis congenita (DKC). Here, we describe a novel TERT mutation at position T1129P leading to DKC with pr...
  15. Inflammation-Induced Emergency Megakaryopoiesis Driven by Hematopoietic Stem Cell-like Megakaryocyte Progenitors.

    Cell Stem Cell 17(4):422 (2015) PMID 26299573

    Infections are associated with extensive platelet consumption, representing a high risk for health. However, the mechanism coordinating the rapid regeneration of the platelet pool during such stress conditions remains unclear. Here, we report that the phenotypic hematopoietic stem cell (HSC) com...
  16. A Synergistic Interaction between Chk1- and MK2 Inhibitors in KRAS-Mutant Cancer

    Cell 162(5):1169 (2015)

  17. The rarity of ALDH(+) cells is the key to separation of normal versus leukemia stem cells by ALDH activity in AML patients.

    International Journal of Cancer 137(3):525 (2015) PMID 25545165 PMCID PMC4755039

    To understand the precise disease driving mechanisms in acute myeloid leukemia (AML), comparison of patient matched hematopoietic stem cells (HSC) and leukemia stem cells (LSC) is essential. In this analysis, we have examined the value of aldehyde dehydrogenase (ALDH) activity in combination wit...
  18. A Synergistic Interaction between Chk1- and MK2 Inhibitors in KRAS-Mutant Cancer.

    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...
  19. Suppression of early hematogenous dissemination of human breast cancer cells to bone marrow by retinoic Acid-induced 2.

    Cancer Discovery 5(5):506 (2015) PMID 25716347

    Regulatory pathways that drive early hematogenous dissemination of tumor cells are insufficiently defined. Here, we used the presence of disseminated tumor cells (DTC) in the bone marrow to define patients with early disseminated breast cancer and identified low retinoic acid-induced 2 (RAI2) ex...
  20. Exit from dormancy provokes DNA-damage-induced attrition in haematopoietic stem cells.

    Nature 520(7548):549 (2015) PMID 25707806

    Haematopoietic stem cells (HSCs) are responsible for the lifelong production of blood cells. The accumulation of DNA damage in HSCs is a hallmark of ageing and is probably a major contributing factor in age-related tissue degeneration and malignant transformation. A number of accelerated ageing ...
