Most cancer tissues showed in general weak cytoplasmic positivity. Papillary adenocarcinomas of the thyroid showed strong cytoplasmic immunoreactivity. Several cases of colorectal cancer, gliomas and melanomas were moderately stained.

Phosphodiesterase 7B (HGNC Symbol)
Entrez gene summary
The 3',5'-cyclic nucleotides cAMP and cGMP function as second messengers in a wide variety of signal transduction pathways. 3',5'-cyclic nucleotide phosphodiesterases (PDEs) catalyze the hydrolysis of cAMP and cGMP to the corresponding 5'-monophosphates and provide a mechanism to downregulate cAMP and cGMP signaling. This gene encodes a cAMP-specific phosphodiesterase, a member of the cyclic nucleotide phosphodiesterase family.[provided by RefSeq, Apr 2009]
