Publication number: 20190043403Abstract: The present invention concerns a method for assigning a pixel to one of a foreground pixel set and a background pixel set. In this method, if a first condition is met the pixel is assigned to the background pixel set, and if the first condition is not met and a second condition is met, the pixel is assigned to the foreground pixel set. The method comprises a step (S100) of calculating a probability that the pixel belongs to a foreground-relevant object according to a semantic segmentation algorithm, the first condition is that this probability that the pixel belongs to a foreground-relevant object does not exceed a first predetermined threshold, and the second condition is that a difference between this probability that the pixel belongs to a foreground-relevant object and a baseline probability for the pixel equals or exceeds a second predetermined threshold.Type: ApplicationFiled: May 18, 2018Publication date: February 7, 2019Applicant: Université de LiègeInventors: Marc VAN DROOGENBROECK, Marc Braham, Sébastien Pierard

Patent number: 9783615Abstract: The present invention provides MT4-MMP inhibitor and EGFR inhibitor for use in the treatment of cancer, wherein said MT4-MMP inhibitor and EGFR inhibitor are different from each other. MT4-MMP (MMP-17) is a glycosylphosphatidyl inositol (GPI) anchored MMP produced by cancer cells that promotes tumor vascularization and metastases. The present invention found that MT4-MMP expression promotes cancer cell proliferation. These effects involve retinoblastoma protein (Rb) inactivation, cyclin dependent kinase CDK4 activation and Epidermal Growth Factor Receptor (EGFR) signaling. Co-immuno-precipitations indicate the existence of protein complexes harboring MT4-MMP and EGFR. The present invention further found a novel mechanism of MT4-MMP action through an outside-in signaling involving EGFR. An unexpected crosstalk between an MMP and EGFR was identified and recognized as a key driver of cancer cell biology.Type: GrantFiled: September 2, 2013Date of Patent: October 10, 2017Assignee: UNIVERSITE DE LIEGEInventors: Agnès Noel, Nor Eddine Sounni, Alexandra Paye
