Sialyl-Tn antigen (STn), which covers bladder cancer cells, contributes to the immune escape of these cells

Tumor cells often have aberrant post-translational modifications of their proteins. In bladder cancer, one of these modifications is the sialyl-Tn (STn) glycan, which is not expressed by normal cells and is highly expressed in high-grade bladder cancer cells. It is known that the immune response is affected by tumor cells, promoting tumor progression. However, little is known about the role of STn in the immune response and its influence on immune cells. Dendritic cells (DCs) play a crucial role in the immune response against tumor cells.

O antigénio Sialil-Tn (STn) que reveste as células de cancro de bexiga contribui para o escape imunológico destas células

As células tumorais apresentam frequentemente modificações pós-translacionais aberrantes das suas proteínas. Em cancro de bexiga, uma destas modificações é o glicano Sialil-Tn (STn), que não é expresso por células normais e encontra-se altamente expresso em células de cancro de bexiga de alto grau de malignidade. Sabe-se que a resposta imune é afetada pelas células tumorais, no sentido de promover a progressão tumoral. No entanto pouco se sabia sobre o papel do STn na resposta imune e da sua influência nas células imunológicas.

MLK3 gene alterations affect WNT signaling

This work follows the one published in 2010 by Sérgia Velho from Professor Raquel Seruca’s group at IPATIMUP, in which MLK3 mutations were for the first described to occur in gastric and colorectal cancers. These mutations were associated with the induction of invasive potential of cancer cells. In the present work, the authors performed expression microarray analysis in order to determine the signaling pathways underlying the oncogenic properties of mutant MLK3.

Alterações do gene MLK3 interferem com a regulação da via de sinalização WNT

Mutações no gene MLK3 foram descritas pela primeira vez em cancro gástrico e colo-retal pelo grupo da Professora Raquel Seruca (IPATIMUP) e o seu efeito oncogénico foi associado à indução de invasão das células tumorais. No trabalho recentemente publicado na revista BMC Cancer, o mesmo grupo estudou as vias de sinalização subjacentes ao efeito oncogénico do gene MLK3.
