Vertical inhibition of p110α/AKT and N‐cadherin enhances treatment efficacy in PIK3CA‐aberrated ovarian cancer cells

Molecular Oncology, EarlyView.
PIK3CA amplification and PIK3CA mutation enhance ovarian tumorigenicity through an activation of AKT, which phosphorylates YAP at Ser127. This Ser127 phosphorylation leads to the retention of YAP in the cytoplasm and triggers RAC1 activity, promoting cell migration. Additionally, AKT activation increases expression of N‐cadherin, which further enhances

Phospholipid hydroperoxide glutathione peroxidase is the 18-kDa selenoprotein expressed in human tumor cell lines. [PDF]

, 1991
Human tumor cell lines cultured in 75Se-containing media demonstrate four major 75Se-labeled cellular proteins (57, 22, 18, and 12 kDa) on sodium dodecyl sulfate-polyacrylamide gel electrophoresis and autoradiography.

CRISPR targeting of FOXL2 c.402C>G mutation reduces malignant phenotype in granulosa tumor cells and identifies anti‐tumoral compounds

Molecular Oncology, EarlyView.
FOXL2 c.402C>G mutation drives granulosa cell tumors. Using CRISPR technology, we selectively corrected this mutation, reducing malignancy and increasing sensitivity to dasatinib and ketoconazole. Transcriptomic changes revealed potential therapeutic targets, demonstrating CRISPR's promise for treating this rare ovarian cancer.

Blue native polyacrylamide gel electrophoresis (BN-PAGE) for analysis of multiprotein complexes from cellular lysates.

Journal of Visualized Experiments, 2011
Multiprotein complexes (MPCs) play a crucial role in cell signalling, since most proteins can be found in functional or regulatory complexes with other proteins (Sali, Glaeser et al. 2003). Thus, the study of protein-protein interaction networks requires

Variations on a theme: Changes to electrophoretic separations that can make a difference [PDF]

Journal of proteomics (2010) epub ahead of print, 2010
Electrophoretic separations of proteins are widely used in proteomic analyses, and rely heavily on SDS electrophoresis. This mode of separation is almost exclusively used when a single dimension separation is performed, and generally represents the second dimension of two-dimensional separations.

ShcD adaptor protein drives invasion of triple negative breast cancer cells by aberrant activation of EGFR signaling

Molecular Oncology, EarlyView.
We identified adaptor protein ShcD as upregulated in triple‐negative breast cancer and found its expression to be correlated with reduced patient survival and increased invasion in cell models. Using a proteomic screen, we identified novel ShcD binding partners involved in EGFR signaling pathways.

Overproduction and Characterization of the Bacillus subtilis Anti-sigma Factor FlgM [PDF]

, 1999
FlgM is an anti-sigma factor of the flagellar-specific sigma (sigma) subunit of RNA polymerase in Bacillus subtilis, and it is responsible of the coupling of late flagellar gene expression to the completion of the hook-basal body structure.

Expression and purification of E140 protein antigen fragments of Plasmodium vivax and Plasmodium berghei for serological assays

FEBS Open Bio, EarlyView.
We provide a step‐by‐step guide for producing E140 antigen fragments from Plasmodium berghei (Pb1) and Plasmodium vivax (Pv1). Pb1/Pv1 are expressed in E. coli, solubilized by freeze–thawing, refolded by slow dilution, purified by affinity chromatography (IMAC), then concentrated and subjected to quality control.

Electrophoretic analysis, labeling and isolation of Chlamydomonas reinhardtii flagellum membrane proteins

Acta Societatis Botanicorum Poloniae, 2015
SDS-polyacrylamide electrophoretic patterns of Chlamydomonas flagellum membrane proteins displayad 6 fractions, 3 PAS-positive among them. The surface radiolabeling of the flagellum membrane suggested an outer surface exposure of fraction '5', and ...
