CSPG4

CSPG4

A gene on chromosome 15q24.2 that encodes a chondroitin sulphate proteoglycan, which may be involved in modulating neuronal adhesion and migration as well as neurite growth during development by binding to neural cell adhesion molecules.

Since ATMSCs cultured in PCM did not express the nPC markers under study, we assessed the expression of genes that code for CD271, CD34, and NG2 (NGFR, CD34, and CSPG4, resp.) after coculture of ATMSCs with murine ECs (endothelial cell line EOMA) on Matrigel[R] (Supplementary Materials).
Pilot experiments demonstrated increased expression of CSPG4, NGFR, and CD34 (genes that code for NG2, CD271, and CD34, resp.) in ATMSCs that were cocultured with murine ECs on Matrigel (Supplementary Table 3).

In more recent work, Alcantara Llaguno et al (88) used the Ascl1 promoter and the Cspg4 (encoding NG2) promoter as drivers for cre-ER to further specifically target oncogenic alterations to both committed neural progenitor cells and adult OPCs, and adult OPCs only, respectively.
In tumors, placental-like CS chains are linked to a limited repertoire of cancer-associated proteoglycans including CD44 and CSPG4. The rVAR2 protein localizes to tumors in vivo and rVAR2 fused to diphtheria toxin or conjugated to hemiasterlin compounds strongly inhibits in vivo tumor cell growth and metastasis.
The chrondroitin sulfate proteoglycan (CSPG4) regulates human trophoblast function.
Seven proteins (Rho-related BTB domain containing protein 3 (RhoBTB3), zinc finger and BTB domain containing protein 44 (ZTBT44), obscurin isoform B, BAI1, RNA exonuclease 1 homolog, death-associated protein kinase 3 (DAPK3), and chondroitin sulfate proteoglycan 4 protein (CSPG4)) showed restricted expression in 1 to 3 groups.
DAPK3 and CSPG4 were both highly expressed in control and greatly reduced or absent in the patient groups.
