Project description:Preclinical cancer drug discovery efforts have employed two-dimensional (2D)-cell-based assay models, which fail to forecast in vivo efficacy and contribute to a lower success rates of clinical approval. Three-dimensional (3D) cell culture models are recently expected to bridge the gap between 2D and in vivo models. We have developed novel 3D culture method that improves the growth of spheroid-forming cancer cells under anchorage-independent condition by leveraging a feature of FP001. Gene microarrays were used to observe the global gene expression in A549 cells cultured in multi-well plate with or without FP001 and identified distinct classes of up or down-regulated genes. A549 cells were cultured for 5 days in normal attachment plate with normal medium (as control) or normal attachment plate with FP001 containing medium. Each sample was collected three times.

We have developed novel 3D culture method that improves the growth of spheroid-forming cancer cells under anchorage-independent condition by leveraging a feature of FP001. Gene microarrays were used to observe the global gene expression in A549 cells cultured with normal adhesion plate (2D, control) or with low adhesion plate (+FP001) and identified distinct classes of up or down-regulated genes. A549 cells were cultured for 5 days in three different conditions as follows. (1) Normal attachment plates with normal medium (as control), (2) low-attachment plates with normal medium, (3) low-attachment plates with FP001 containing medium. Each sample was collected three times.
Project description:A549 and MDA-MB-231 cells were cultured in 2D and Matrigel based 3D culture for 4 days. Total RNA was extracted using Trizol. RNA-SEQ was carried out to profile the gene expression in both culture conditions.

Three-dimensional (3D) cell culture models are recently expected to bridge the gap between 2D and in vivo models. We have developed a novel 3D culture method that is suitable for imaging analysis and improves the growth of spheroid-forming cancer cells under anchorage-independent condition by leveraging a feature of LA717, a seaweed-derived polysaccharide. Gene microarrays were used to observe the global gene expression in A549 cells cultured with or without LA717 and identified distinct classes of up or down-regulated genes.

Project description:HCV proliferation is closely related to three-dimentional cellular condition. In case of blood-borne (bb) HCV culture in HuS-E2 cells, bbHCV was reproduced only from 3D-cultured cells in hollow fibers. Thus, in order to identify novel factors which support HCV proliferation under three-dimentional condition, we compared gene expression profile between 2D- and 3D-cultured HuS-E/2 cells with 3D-gene Human oligo chip 25k (Toray, Tokyo, Japan).
