Title |
DwoC_2318_30mM (SC.132) |
Sample type |
RNA |
|
|
Source name |
Lymphoblastoid cell line
|
Organism |
Homo sapiens |
Characteristics |
cell line: Lymphoblastoid cell line
|
Treatment protocol |
All lymphoblastoid cell lines were maintained in conventional lymphocyte cell culture conditions of RPMI 1640 with 10% FBS in a 25-cm2 cell culture flask. The cells were incubated at 370C in 5% CO2 and the media was changed twice each week. Prior to the experiments (below), lymphoblastoid cells following serum starvation were passaged for a minimum of one week in either standard (SG) RPMI 1640 (11mM glucose) or high glucose (HG) RPMI media (30mM glucose)
|
Growth protocol |
Lymphoblastoid cell lines were thawed and cultured in RPMI and 10% FBS until they reached over 85% cell viability. Cells were seeded in a T25 flask. Two replicates were performed per cell line. Cells were counted every day or every other day for five to ten days and recorded.

Description |
SC.132
|
Data processing |
Analysis of the gene expression data was performed as follows. For a given individual Si (i= 1,…,22) and gene Gk (k= 1,...,15591), we calculated ∆i,k= HGi,k - SGi,k, where ∆ is response to glucose RG, HG is gene expression in high glucose culture, and SG is gene expression in standard glucose culture. All replicate data was fit using a mixed model that accounted for the correlation between repeated measures within individuals. We built a design matrix using the model.matrix function, and accounted for correlation between biological triplicates using limma’s duplicatecorrelation function. A mixed linear model was then fit that incorporates this correlation and ∆i,k (where ∆ is response to glucose, RG = HGi,k - SGi,k) using the lmFit function. The analysis was performed using the R package limma
