BMP2 Knockout 786-O Polyclonal Cells provide a CRISPR/Cas9-edited polyclonal knockout population derived from the 786-O human renal cell carcinoma line, featuring targeted disruption of the BMP2 gene. BMP2 encodes a secreted TGF-beta superfamily ligand involved in osteoblast differentiation, bone formation, and embryonic development. This polyclonal cell pool eliminates the need for single-cell cloning, enabling direct loss-of-function analysis in a mixed edited population.
The 786-O line is a well-characterized model of clear cell renal cell carcinoma (ccRCC), harboring a mutant VHL gene that drives constitutive HIF activation. This epithelial tumor cell line is widely employed to study renal cancer biology, providing a clinically relevant platform to investigate how BMP2 disruption affects tumorigenic properties under VHL-deficient conditions.
BMP2 signals through heteromeric complexes of type I (ALK3/BMPR1A, ALK6/BMPR1B) and type II (BMPR2) serine/threonine kinase receptors, leading to phosphorylation of SMAD1/5/8. These R-SMADs complex with SMAD4 and translocate to the nucleus, regulating transcription of target genes such as ID1, ID2, DLX5, RUNX2, ALP, and OCN. Signaling is modulated by extracellular antagonists (Noggin, Chordin, Gremlin) and intersects with non-canonical MAPK (ERK, p38) and PI3K-Akt pathways. Upstream regulators include retinoic acid, Hedgehog, Wnt, and inflammatory cytokines like TNF-alpha and IL-1beta.
In the 786-O context, BMP2 can influence cell proliferation, migration, and epithelial-mesenchymal transition, contributing to ccRCC progression and potential bone metastasis. Knocking out BMP2 in these cells allows dissection of its role in VHL-mutant renal carcinoma, including crosstalk with pathways such as Wnt and Hedgehog. Moreover, because BMP2 is critical for bone homeostasis, this model is pertinent for investigating tumor?Cbone microenvironment interactions and osteolytic or osteoblastic lesion mechanisms.
Researchers can utilize these polyclonal knockout cells for western blotting of BMP2 and phospho-SMAD1/5, RT-qPCR of downstream genes, cell proliferation and migration assays, alkaline phosphatase activity measurements, and RNA-seq to profile transcriptomic changes. Co-culture systems with osteoblasts or bone matrices can assess metastatic potential. For further information, please contact Ascent Research.
