Continuous quantification of HER2 expression by microfluidic precision immunofluorescence estimates HER2 gene amplification in breast cancer

Martinus Gijs, Ata Tuna Ciftlik, Diego Gabriel Dupouy, Maryse Fiche, Déborah Heintze

Chromogenic immunohistochemistry (IHC) is omnipresent in cancer diagnosis, but has also been criticized for its technical limit in quantifying the level of protein expression on tissue sections, thus potentially masking clinically relevant data. Shifting f ...

Functional Perturbation of the Gab2 Multiprotein Complex by High-affinity SH2-binding Monobodies in Chronic Myelogenous Leukemia

Emel Basak Gencer Akçok

Chronic myeloid leukemia is characterized by a reciprocal chromosomal translocation between chromosome 9 and 22, resulting in the expression of the Bcr-Abl oncoprotein. Despite the great improvement in patient survival using tyrosine kinase inhibitors (TKI ...

Phage selection of bicyclic peptides binding Her2

Christian Heinis, Philippe Diderich

Aberrant expression of the epidermal growth factor receptor Her2 has been implicated in various malignancies including breast cancer. Monoclonal antibodies and an antibody drug conjugate targeting Her2 have found wide clinical application. Herein, we aimed ...

Development of bicyclic peptide Her2 binders and phage selection of alpha-helical peptide ligands

Philippe Diderich

Conformationally constrained peptide ligands offer an attractive format for the development of therapeutics. They can bind with high affinity and selectivity to protein targets, they are small enough to diffuse into tissues, they can be synthesized chemica ...

The SH2 domain of Abl kinases regulates kinase autophosphorylation by controlling activation loop accessibility

Oliver Hantschel, Sandrine Madeleine Suzanne Georgeon, Allan Joaquim Lamontanara

The activity of protein kinases is regulated by multiple molecular mechanisms, and their disruption is a common driver of oncogenesis. A central and almost universal control element of protein kinase activity is the activation loop that utilizes both confo ...

Dissection of the BCR-ABL signaling network using highly specific monobody inhibitors to the SHP2 SH2 domains

Oliver Hantschel, Sandrine Madeleine Suzanne Georgeon, Emel Basak Gencer Akçok

The dysregulated tyrosine kinase BCR-ABL causes chronic myelogenous leukemia in humans and forms a large multiprotein complex that includes the Src-homology 2 (SH2) domain-containing phosphatase 2 (SHP2). The expression of SHP2 is necessary for BCR-ABL-dep ...

Binding of Lassa virus perturbs extracellular matrix-induced signal transduction via dystroglycan

Françoise Gisou van der Goot Grunberg, Marie-Laurence Moraz, Stefan Kunz, Christelle Pythoud

The arenavirus Lassa virus (LASV) causes a severe haemorrhagic fever with high mortality in man. The cellular receptor for LASV is dystroglycan (DG). DG is a ubiquitous receptor for extracellular matrix (ECM) proteins, which cooperates with beta 1 integrin ...

Bioconjugated lanthanide luminescent helicates as multilabels for lab-on-a-chip detection of cancer biomarkers

Martinus Gijs, Jean-Claude Bünzli, Anne-Sophie Chauvin, Caroline Vandevyver, Venkataragavalu Sivagnanam, Bo Song, Vanesa Fernandez Moreira, Hans-Anton Lehr

The lanthanide binuclear helicate [Eu2(LC2(CO2H))3] is coupled to avidin to yield a luminescent bioconjugate EuB1 (Q ¼ 9.3%, s(5D0) ¼ 2.17 ms). MALDI/TOF mass spectrometry confirms the covalent binding of the Eu chelate and UV-visible spectroscopy allows o ...
