The BMP1 Knockout HCT 116 Polyclonal Cells are a genetically engineered loss-of-function model generated through CRISPR/Cas9-mediated disruption of the BMP1 gene within the well-characterized HCT 116 human colorectal carcinoma cell line. This product is supplied as a polyclonal population, eliminating the need for single-cell cloning and providing a heterogeneous knockout pool suitable for diverse functional studies. Functional BMP1 ablation enables researchers to dissect its roles in extracellular matrix (ECM) remodeling and growth factor signaling pathways.
HCT 116 is a widely used epithelial cell line derived from a human colon carcinoma, exhibiting high tumorigenicity and a near-diploid karyotype. Its conserved epithelial morphology and intact signaling pathways, including TGF-?? and Wnt signaling, make it a preferred host for investigating colorectal cancer biology. This cell line is responsive to exogenous TGF-?? ligands and expresses key ECM components, providing a physiologically relevant context for studying BMP1-mediated processes in a cancer setting.
BMP1 encodes a metalloproteinase that functions downstream of TGF-?? ligands, BMP signaling, and mechanical stress. It directly processes type I?CIII procollagens into mature collagen fibrils and activates latent TGF-?? complexes by cleaving latent TGF-?? binding proteins (LTBPs). Interacting partners include procollagens, chordin, and tolloid-like proteinases. Through these activities, BMP1 promotes collagen deposition and integrin engagement, thereby regulating TGF-?? bioavailability and downstream SMAD-dependent transcription. This positions BMP1 as a critical node connecting ECM structural integrity with morphogen signaling.
In the HCT 116 colorectal carcinoma background, BMP1 disruption permits investigation of how impaired collagen maturation and altered TGF-?? activation affect tumor cell behavior. Loss of BMP1 may attenuate ECM stiffness and integrin-mediated adhesion, influencing epithelial-mesenchymal transition (EMT) and invasive potential. Moreover, since TGF-?? exerts dual tumor-suppressive and tumor-promoting effects depending on the cellular environment, this knockout model enables controlled dissection of BMP1??s contribution to TGF-?? signaling bias in colorectal cancer progression and fibrotic-like stromal reactions.
This polyclonal knockout cell population is designed for applications such as fibrotic disease modeling, extracellular matrix biology, and tumor microenvironment studies. Researchers can employ western blotting to monitor procollagen processing, RT-qPCR to quantify ECM gene expression changes, and immunofluorescence to visualize collagen deposition. Cell migration and invasion assays, combined with TGF-??-responsive luciferase reporters, provide functional readouts of signaling pathway activity.
