RHOA and T-cell non-Hodgkin lymphoma: Interestingly, we could not demonstrate enhanced MMP secretion in the T-cell lymphoma cell lines expressing RHOA-G17V; however, we cannot rule out that RHOA-G17V-expressing T cells can stimulate fibroblasts or other cells in the microenvironment to secrete MMPs and thus contribute to the remodelling of the extracellular matrix.
