Among these 28 genes, 12 were more highly expressed in pCR tumour samples (WEE1, ZNF146, SENP7, GPR22, KIAA1549, SYNCRIP, SLC30A6, GRHL2, CCDC123, LOC340171, STX1A, cDNA FLJ11973 fis, and clone HEMBB1001221), and 16 genes were highly expressed in non-pCR samples (LOC158402, PITPNA, PPP2CA, SLC35A4, NFE2L1, C5orf3, PEX19, P2RX1, CDC14A, SENP8, PSMD11, CTNS, DER1, PRKACA, LAMA3, and FLJ20160) (Table 4). This evidence concerns the gene SLC35A4 and neoplasm.
