Abstract:
The therapy for breast cancer (BC), to date, still needs improvement. Apart from traditional therapy methods, biological therapy being explored opens up a novel avenue for BC patients. Integrin β1 (ITGβ1), one of the largest subgroups in integrin family, is a key player in cancer evolution and therapy. Recent researches progress in the relationship of ITGβ1 level and BC, finding that ITGβ1 expression evidently concerns BC progression. In this chapter, we outline diverse ITGβ1-based mechanisms regarding to the promoted effect of ITGβ1 on BC cell structure rearrangement and malignant phenotype behaviors, the unfavorable patient prognosis conferred by ITGβ1, BC therapy tolerance induced by ITGβ1, and lastly novel inhibitors targeting ITGβ1 for BC therapy. As an effective biomarker, ITGβ1 undoubtedly emerges one of targeted-therapy opportunities of BC patients in future. It is a necessity focusing on scientific and large-scale clinical trials on the validation of targeted-ITGβ1 drugs for BC patients.

Activation of Integrins
In "outside-in signaling," external factors in the extracellular space bind to exposed ligand binding sites on integrins. This causes the inactive protein to undergo a conformational change to become active. Integrins are often clustered on the cell membrane. Repetitive and regularly spaced ligand binding...

Some ECM proteins assemble into a basement membrane to which the remaining components adhere. Proteoglycans typically form the bulk of the ECM while fibrous proteins, like collagen,...
Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
