T gene isoform expression pattern is significantly different between chordomas and notochords.
The T gene plays a key role in chordoma pathology. To investigate the role of T gene isoforms in chordoma, 22 skull base chordomas, three chordoma cell lines and 9 infant notochords, which were used as normal controls, were collected. We first conducted droplet digital PCR to quantify the absolute expression levels of the long and short isoforms of the T gene (T-long and T-short, respectively) and revealed that T-long was dominantly expressed in all chordomas and chordoma cell lines, but not in the notochords. ⋯ In conclusion, two T gene isoforms were investigated in skull base chordomas and chordoma cell lines, and the longer isoform was dominantly expressed. The distinct expression patterns of these T gene isoforms may contribute to the pathogenesis of skull base chordomas. However, further studies on the function of these isoforms are needed.
