Project description:LMSU gastric cancer cells were manipulated to either knockout or knockdown mutant p53-R175H, which is endogenously mutated and expressed in this cell line.
Project description:To develop a syngeneic mouse model of metastatic gastric cancer, we established the tumor organoids from gastric tumor arising in GAstric Neoplasia (GAN) mice (GAN-WT) which express Wnt1 and the PGE2 synthesis enzymes COX-2 and microsomal prostaglandin E synthase-1 (mPGES-1) in the stomach epithelium. Furthemore, GAN-WT organoids were genetically manupilated into p53 knockout organoids (GAN-p53KO) and KrasG12V-expressing GAN-p53KO organoids (GAN-KP).
Project description:Human embryonic stem cells (WA01) were differentiated in a step-wise manner into three-dimensional human gastric organoids (hGOs). At day 34 of differentiation, the hGOs were collected and analyzed by RNA-sequencing.
