- Activation of RAC1/PAK1 axis potentiates transcriptional upregulation of DNA damage response genes via the BCL6/STAT5 switchPublication . Barros, Patrícia; Amaral, Andreia; Abrantes, Leonor; Oliveira, Tiago; Lourio, Henriqueta; Silva, Maria João; Jordan, Peter; Gama-Carvalho, Margarida; Matos, PauloColorectal cancer is one of the most prevalent types of cancer worldwide. The GTPase RAC1 and its effector PAK1 have been found overexpressed or hyperactivated in colorectal cancers, particularly those with more aggressive and invasive features, leading to unfavourable clinical prognosis, often resulting from chemoresistance.
- Stimulation of RAC1/PAK1 signalling upregulates DNA damage repair genes via STAT5 stimulation of BCL6 repressed lociPublication .

- Upregulation of RAC1/PAK1 signalling promotes DNA damage repair in colorectal cancer cellsPublication . Barros, Patricia; Amaral, Andreia; Abrantes, Leonor; Oliveira, Tiago; Louro, Henriqueta; Silva, Maria Joâo; Jordan, Peter; Gama Carvalho, Margarida; Matos, PauloIntroduction: Colorectal cancer is one of the most prevalent types of cancer worldwide. The GTPase RAC1 and its effector PAK1 have been found overexpressed or hyperactivated in this type of cancers, particularly those with more aggressive and invasive features, which is frequently correlated with resistance to chemotherapeutics and unfavourable clinical prognosis. Previously, we described a new signalling pathway in which activation of RAC1/PAK1 signalling promotes a transcriptional switch between the BCL6 repressor and the STAT5 transcriptional activator at a restricted subset of gene promoters.
