Researchers from IMIM (Hospital del Mar Medical Research Institute) lead by Dr. Sandra Peiró have described a new function for two key molecules involved in tumor progression. Transcription factor SNAIL1 and enzyme LOXL2 are essential to Epithelial-Mesenchymal Transition (EMT); meaning the process by which tumor cells are able to move and reach other tissues. The study has been published in the Molecular Cell Journal and places enzyme LOXL2 as a possible therapeutic target to treat cancers such as breast, lung or skin cancer.
Transcription factors are proteins that regulate gene expression. They activate or deactivate a gene’s function. Researchers at IMIM have studied the function of one of these transcription factors, Snail1, in mouse cells during the Epithelial-Mesenchymal Transition (EMT). Sandra Peiró, a researcher from the IMIM Research Group on Epithelial-Mesenchymal Transition and Tumor Progression explains: “EMT is a process consisting of converting epithelial cells, the ones covering the internal and external surfaces of the body, into what are known as mesenchymal cells. In this process, the cells acquire a series of new characteristics that enable them to migrate and resist apoptosis (programmed cell death), self-regenerate and, finally, invade neighboring tissues and reach other areas of the body. When this process occurs at the tumor epithelial cells, the resulting mesenchymal cells can migrate and generate metastases”.
