COL11A1 and invasive carcinoma: Vázquez-Villa et al. found that COL11A1/(pro)collagen 11A1 is highly expressed in activated stromal cells of the DR of different human invasive carcinomas, and this expression is correlated with cancer aggressiveness, progression, and lymph node metastasis, while COL11A1/(pro)collagen 11A1 is not expressed in stromal cells under normal conditions.
