MYSM1 and adenocarcinoma: A tissue microarray containing 38 adjacent normal tissues (N), 53 adenocarcinomas (T) and 33 lymph node metastatic carcinomas (M) was analyzed and revealed that MYSM1 expression, which was predominantly in the nucleus, was significantly higher in adjacent normal tissues and lower in lymph node metastatic carcinomas than in primary adenocarcinomas (Fig. 2A and Table 1).
