HA-1077 inhibits cell migration/invasion of oral squamous cell carcinoma.

Oral squamous cell carcinoma (OSCC) is the most malignant lesion occurring in the head and neck. The Rho-kinases (ROCKs), effectors of Rho proteins, are involved in actin cytoskeletal organization, cell migration, and maintenance cortex. The HA-1077 inhibits the ROCKs.

Immunolocalization of RhoA and RhoB GTPases in pleomorphic adenoma of the parotid.

The pleomorphic adenoma of the parotid (PA) is characterized by the high tissues diversity. Rho GTPases participate in signal transduction pathways that regulate several biological processes, including cell differentiation. A quantitative analysis of RhoA and RhoB GTPases immunoexpression was performed in healthy parotids and in 23 PA cases, predominantly epithelial (PE) or mesenchymal (PM), followed by Student's t test.
