In this study, the authors combined the use of genome editing tools and last generation inducible systems in order to develop a cell model where the expression of CDX2 transcription factor can be tightly regulated. CDX2 is an intestinal differentiation marker whose expression is often altered in gastric and colon carcinomas. Its control was here shown to be useful to uncover novel putative downstream effector genes (such as GPA33 and LDLR), and therefore, to further clarify the role of CDX2 in intestinal cells.

In this study, a comparative analysis of the volatile metabolomic signature of BC cell lines (T-47D, MDA-MB-231, MCF-7) and normal human mammary epithelial cells (HMEC), was carried out, in order to identify BC-specific VOCs and to identify a set of markers that could hopefully be correlated with VOCs released in vivo by BC cells.
Este trabalho, integrado no projeto de doutoramento da Catarina L. Silva, recentemente publicado na revista Scientific Reports, e inserido num projeto Europeu com a participação de investigadores de Portugal (coordenador principal), Alemanha e India, aprovado pelo programa New Indigo, permitiu estabelecer o perfil volátil de diferentes linhas celulares de cancro da mama, com o objetivo de identificar metabolitos voláteis produzidos por este tipo de células.

Um estudo liderado por investigadores da CESPU, Patrícia Silva e Hassan Bousbaa, publicado na prestigiosa revista “Cancer Letters” de 28 de maio de 2017, revela que a eliminação seletiva da Spindly, uma proteína necessária para a divisão correta das células normais, obriga as células cancerígenas tratadas por agentes quimioterápicos clássicos, a suicidar-se. Esta estratégia poderá ser um auxílio valioso aos agentes clássicos, como o paclitaxel, no combate ao cancro.
