Identification of differentially expressed microRNAs in human male breast cancer
- U. Lehmann, T. Streichert, +7 authors F. Länger
- Biology, Medicine
- BMC Cancer
- 23 March 2010
BackgroundThe discovery of small non-coding RNAs and the subsequent analysis of microRNA expression patterns in human cancer specimens have provided completely new insights into cancer biology.… Expand
High frequency of lobular breast cancer in distant metastases to the orbit
- M. Raap, Wiebke Antonopoulos, +6 authors M. Christgen
- Medicine
- Cancer medicine
- 30 October 2014
Metastasis to the periocular soft tissue of the orbit is a rare manifestation of metastatic cancer. Infiltrating lobular breast cancer (ILBC) is a special breast cancer subtype, which accounts for… Expand
The region-of-interest size impacts on Ki67 quantification by computer-assisted image analysis in breast cancer.
- M. Christgen, Sabrina von Ahsen, Henriette Christgen, F. Länger, H. Kreipe
- Mathematics, Medicine
- Human pathology
- 1 September 2015
Therapeutic decision-making in breast cancer depends on histopathologic biomarkers and is influenced by the Ki67 proliferation index. Computer-assisted image analysis (CAIA) promises to improve Ki67… Expand
Lobular carcinoma in situ and invasive lobular breast cancer are characterized by enhanced expression of transcription factor AP-2β
- M. Raap, M. Gronewold, +15 authors M. Christgen
- Biology, Medicine
- Laboratory Investigation
- 2018
Transcription factor AP-2β (TFAP2B) regulates embryonic organ development and is overexpressed in alveolar rhabdomyosarcoma, a rare childhood malignancy. Gene expression profiling has implicated… Expand
ERBB2 mutation frequency in lobular breast cancer with pleomorphic histology or high‐risk characteristics by molecular expression profiling
- M. Christgen, S. Bartels, +8 authors H. Kreipe
- Biology, Medicine
- Genes, chromosomes & cancer
- 1 March 2019
HER2‐positive breast cancer is defined by amplification or overexpression of the HER2/ERBB2 oncogene and accounts for about 15% of breast cancer cases. Somatic mutation of ERBB2 is an alternative… Expand
Oncogenic PIK3CA mutations in lobular breast cancer progression
- M. Christgen, M. Noskowicz, +6 authors U. Lehmann
- Biology, Medicine
- Genes, chromosomes & cancer
- 1 January 2013
Infiltrating lobular breast cancer (ILBC) is a tumor‐biologically distinct breast cancer subtype. A high frequency of oncogenic PIK3CA mutations has been reported in ILBC, which may allow for… Expand
IPH-926 lobular breast cancer cells harbor a p53 mutant with temperature-sensitive functional activity and allow for profiling of p53-responsive genes
- M. Christgen, M. Noskowicz, +5 authors U. Lehmann
- Biology, Medicine
- Laboratory Investigation
- 3 September 2012
Profiling of p53-responsive genes has been carried out in different cellular models, most of which involved genetic modifications or cytotoxic stimulation. We report on the utilization of IPH-926… Expand
Down-regulation of the Fetal Stem Cell Factor SOX17 by H33342
- M. Christgen, R. Geffers, +5 authors U. Lehmann
- Biology, Medicine
- The Journal of Biological Chemistry
- 29 December 2009
Human solid tumors contain rare cancer side population (SP) cells, which expel the fluorescent dye Hoechst 33342 (H33342) and display cancer stem cell characteristics. Transcriptional profiling of… Expand
Is Upregulation of BCL2 a Determinant of Tumor Development Driven by Inactivation of CDH1/E-Cadherin?
- Inga Karch, E. Schipper, Henriette Christgen, H. Kreipe, U. Lehmann, M. Christgen
- Biology, Medicine
- PloS one
- 30 August 2013
Inactivation of CDH1, encoding E-cadherin, promotes cancer initiation and progression. According to a newly proposed molecular mechanism, loss of E-cadherin triggers an upregulation of the… Expand
Expression of KAI1/CD82 in distant metastases from estrogen receptor‐negative breast cancer
- M. Christgen, Henriette Christgen, +4 authors U. Lehmann
- Biology, Medicine
- Cancer science
- 1 September 2009
The tetraspanin protein superfamily member KAI1 suppresses tumor growth and metastasis in animal models and is downregulated in various human malignancies. In breast cancer, KAI1 is preferentially… Expand
