A majority of malignant cells showed moderate cytoplasmic staining with a granular pattern, often accompanied with nuclear staining in a fraction of the cells. Several prostate cancers were strongly stained, while most testicular, urothelial, renal and hepatocellular carcinomas were weakly stained or negative.
Mucinous ovarian cancers and fractions of cells in cases of colorectal cancers displayed strong staining. A majority of testicular cancers as well as a few breast, prostate, skin and urothelial cancers displayed moderate cytoplasmic positivity. Subsets of cells in malignant gliomas showed moderate nuclear staining. Malignant cells in general showed weak staining or were negative.

Description
Early growth response 3 (HGNC Symbol)
Entrez gene summary
This gene encodes a transcriptional regulator that belongs to the EGR family of C2H2-type zinc-finger proteins. It is an immediate-early growth response gene which is induced by mitogenic stimulation. The protein encoded by this gene participates in the transcriptional regulation of genes in controling biological rhythm. It may also play a role in a wide variety of processes including muscle development, lymphocyte development, endothelial cell growth and migration, and neuronal development. Alternative splicing results in multiple transcript variants encoding distinct isoforms.[provided by RefSeq, Dec 2010]
