6.7 Is<strong>of</strong>orm Differential Expression Results<br />

148<br />

Figure 6.15: BMP7 encodes a member <strong>of</strong> the TGFβ superfamily and is represented in our Tag-seq data by two tags that identify transcripts <strong>of</strong><br />

different lengths. The expression levels across our GNS cell lines (top) are in blue (plus strand) and red (minus strand). BMP7, like other members<br />

<strong>of</strong> the bone morphogenetic protein family, plays a key role in the transformation <strong>of</strong> mesenchymal cells into bone and cartilage. However, BMP7 has<br />

also been recently implicated in the suppression <strong>of</strong> tumourigenicity <strong>of</strong> stem-like GBM cells when released from endogenous neural precursor cells [97].<br />
