3076454-4	1988	In contrast, K13 was consistently expressed in squamous cell carcinomas of the skin induced by 7,12-dimethylbenz[a]anthracene and 12-O-tetradecanoylphorbol-13-acetate (TPA), whereas papillomas obtained by the same two-stage protocol were distinctly heterogeneous with regard to the expression of this keratin.	anthracene	115-125	keratin 13	Mus musculus	13-16	
1711471-2	1991	Recently, however, we were able to show that K13 is aberrantly but constitutively expressed without its normal type II partner K4 also in differentiating parts of 7,12-dimethylbenz(a)anthracene (DMBA/TPA) 12-O-tetradecanoylphorbol-13-acetate-induced squamous cell carcinomas of mouse back skin, whereas its likewise suprabasal expression in papillomas is variable (Nischt et al., Mol.	anthracene	183-193	keratin 13	Mus musculus	45-48	
7525098-1	1994	The type I keratin K13, normally restricted to suprabasal cells of internal stratified epithelia, is aberrantly expressed in 7,12-dimethylbenz[a]anthracene (DMBA)-12-O-tetradecanoyl-phorbol-13-acetate-induced murine epidermal tumors and constitutes an early marker of malignant progression.	anthracene	145-155	keratin 13	Mus musculus	19-22	
1724371-2	1991	In this study, we investigated v-Ha-ras-induced papillomas for aberrant expression of type I keratin K13, previously described in 7,12-dimethylbenz[a]anthracene/12-O-tetradecanoylphorbol-13- acetate (DMBA/TPA)-induced mouse epidermal tumors.	anthracene	150-160	keratin 13	Mus musculus	101-104
