PG - 157-167 LID - 10.1007/978-1-0716-2744-0_11 [doi] AB - The Cellular Communication Network Factor (CCN) family is composed of six members: CCN1/CYR61, CCN2/CTGF, CCN3/NOV, CCN4/WISP1, CCN5/WISP2, and CCN6/WISP3. The second member, CCN2/CTGF is a matricellular protein that promotes extracellular matrix (ECM) synthesis and controls angiogenesis. On the other hand, moonlighting/matrix metalloproteinase 3 (MMP3) is an ECM-degrading enzyme that also functions as an intracellular transcription factor. Importantly, extracellular MMP3 is uptaken into cells, translocating into nuclei, and transcriptionally activating CCN2/CTGF gene in cancer and chondrocytes. Thus, the MMP3-CTGF axis balances the matrix metabolism and turnover in the tissue and tumor microenvironments. We established an MMP3 knockout cell line using the CRISPR/Cas9 system, demonstrating the sequential regulatory events of the MMP3-CCN2 axis in the microenvironment. Notably, our protocol is useful for generation of CCN knockout cells as well. Here we serve a protocol of the CRISPR/Cas9-based gene targeting in cultured cells for investigating cellular communication network. CI - (c) 2023.
