However, the limited availability of antibodies is a key barrier to the development of a lower cost alternative, namely a discrete collection of immunohistochemistry (IHC)-based biomarkers. (biomedcentral.com)
The aim of this study was to use a systematic approach to generate and screen affinity-purified, mono-specific antibodies targeting progression-related biomarkers, with a view towards developing a clinically applicable IHC-based prognostic biomarker panel for breast cancer. (biomedcentral.com)

Upon dissociation of the N-terminal fragment, the C-terminus of the GAIN domain acts as a tethered agonist (TA) peptide to activate the seven-transmembrane domain with a mechanism that has been poorly understood2-5. (stanford.edu)

Proteins associated with the Wnt/β-catenin pathway have been identified as SUMOylated substrates, and evidences suggested that the initiation and progression of cancers depended on the function of the SUMOylation ( 23 ). (frontiersin.org)
Complement component 1 Q subcomponent binding protein (C1QBP) plays a vital role in the progression and metabolism of cancer. (medsci.org)
