Patent number: 11814688Abstract: The present application relates to the field of cancer, particular to hypoxic tumors. It was found that hypoxia is an important driver for hypermethylation of (promoters of) tumor suppressor genes. As this hypermethylation is a stable signature that is also present in circulating tumor DNA in peripheral blood, detecting this methylation pattern is a surrogate marker for tumor hypoxia. This can be used to adapt therapy as well.Type: GrantFiled: April 25, 2022Date of Patent: November 14, 2023Assignees: VIB VZW, Katholieke Universiteit Leuven, K.U.

Publication number: 20220203325Abstract: A miniaturized, automated method for controlled printing of large arrays of nano- to femtoliter droplets by actively transporting mother droplets over hydrophilic-in-hydrophobic (“HIH”) micropatches. The technology uses single or double-plate devices where mother droplets can be actuated and HIH micropatches on one or both plates of the device where the droplets are printed. Due to the selective wettability of the hydrophilic micropatches in a hydrophobic matrix, large nano- to femtoliter droplet arrays are created when mother droplets are transported over the arrays. The parent droplets are moved by various droplet actuation principles. Also, a method using two plates placed one top another while being separated by a spacer. One plate is dedicated to confirming and guiding parent droplets by using hydrophilic patches in a hydrophobic matrix, while the other plate contains HIH arrays for printing of the droplets.Type: ApplicationFiled: March 21, 2022Publication date: June 30, 2022Applicant: Katholieke Universiteit Leuven, K.U.Leuven R&DInventors: Jeroen Lammertyn, Daan Witters

Patent number: RE48856Abstract: The application relates to the field of cancer, particularly to the field of solid tumors. It was found that a particular long non-coding RNA (lncRNA), NEAT1, an essential architectural component of nuclear paraspeckles, is required for the survival of cancer, but not that of normal, non-transformed, cells. Inhibition of NEAT1 reduces cell viability of cancer cells and induces apoptosis. These data identify NEAT1 as a novel therapeutic target for treatment of solid tumors.Type: GrantFiled: October 10, 2019Date of Patent: December 21, 2021Assignees: VIB VZW, Katholieke Universiteit Leuven, K.U.Leuven R&DInventors: Jean-Christophe Marine, Laura Standaert
