Oligonucleotide microarray analysis reveals dysregulation of energy-related metabolism in insulin-sensitive tissues of type 2 diabetes patients

M. Wang, Wang, X. C., Zhao, L., Zhang, Y., Yao, L. L., Lin, Y., Peng, Y. D., and Hu, R. M., Oligonucleotide microarray analysis reveals dysregulation of energy-related metabolism in insulin-sensitive tissues of type 2 diabetes patients, vol. 13, pp. 4494-4504, 2014.

Impaired insulin action within skeletal muscle, adipose tissue, and the liver is an important characteristic of type 2 diabetes (T2D). In order to identify common underlying defects in insulin-sensitive tissues that may be involved in the pathogenesis of T2D, the gene expression profiles of skeletal muscle, visceral adipose tissue, and liver from autopsy donors with or without T2D were examined using oligonucleotide microarrays and quantitative reverse transcriptase-PCR.

Positional effects of polymorphisms in probe-target sequences on genoplot images of oligonucleotide microarrays

T. L. Cui, Nakaoka, H., Akiyama, K., Kamura, H., Hosomichi, K., Bae, J., Cheong, H., Shin, H., Yada, T., and Inoue, I., Positional effects of polymorphisms in probe-target sequences on genoplot images of oligonucleotide microarrays, vol. 9, pp. 524-531, 2010.

Single nucleotide polymorphisms (SNPs) present in probe-target sequences (SPTS) have been shown to be associated with abnormal genoplot images. We explored the effects of SPTS positions on genoplot images using a data set from a genome-wide association study typed on an Illumina Human Hap300 platform. We screened the physical genomic positions of 308,330 autosomal probes to identify SPTS candidates deposited in dbSNP. The genoplot images across 293 individuals were inspected further in SNPs bearing an SPTS candidate.
