Moderate cytoplasmic staining was observed in cancer tissues. Several cases of lymphomas and a few cases of colorectal and endometrial cancers were strongly stained.
Cancer tissues showed moderate to strong cytoplasmic staining with membranous positivity in a few cases. Several cases of lymphomas, lung and testicular cancers were weakly stained or negative.
A few cases of lymphomas showed moderate cytoplasmic staining. Remaining cancer tissues were mainly negative.
GENE INFORMATION
Gene name
ROCK1 (HGNC Symbol)
Synonyms
p160ROCK
Description
Rho-associated, coiled-coil containing protein kinase 1 (HGNC Symbol)
Entrez gene summary
This gene encodes a protein serine/threonine kinase that is activated when bound to the GTP-bound form of Rho. The small GTPase Rho regulates formation of focal adhesions and stress fibers of fibroblasts, as well as adhesion and aggregation of platelets and lymphocytes by shuttling between the inactive GDP-bound form and the active GTP-bound form. Rho is also essential in cytokinesis and plays a role in transcriptional activation by serum response factor. This protein, a downstream effector of Rho, phosphorylates and activates LIM kinase, which in turn, phosphorylates cofilin, inhibiting its actin-depolymerizing activity. A pseudogene, related to this gene, is also located on chromosome 18. [provided by RefSeq, Aug 2015]
