Samples included platinum-sensitive, platinum-resistant, and post-chemotherapy teratomas. Platinum-resistant disease was defined as radiological progression and\/or rising tumour markers after first line platinum-based chemotherapy. Platinum-sensitive cases included patients achieving complete response as well as those with residual teratoma requiring post-chemotherapy resection. Differential expression analysis and principal component analysis (PCA) were performed to compare transcriptional patterns across groups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Post-chemotherapy teratomas demonstrated a distinct expression profile, characterised by lower\n                      <jats:italic toggle=\"yes\">POU5F1<\/jats:italic>\n                      (encodes OCT4 protein\n                      <jats:italic toggle=\"yes\">)<\/jats:italic>\n                      expression and higher levels of apoptosis and cell-cycle related genes. In contrast, platinum-resistant and platinum-sensitive primary TGCTs showed substantial overlap in global expression patterns, and no individual gene met thresholds for differential expression. These findings suggest that the transcriptional features of teratoma differentiation are readily detectable with targeted profiling, while platinum resistance is not captured by this gene set.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>NanoString-based targeted expression profiling identifies biologically distinct expression patterns in post-chemotherapy teratomas but did not reveal a unifying transcriptional signature associated with platinum resistance in TGCTs.
