Transcriptome sequencing of Chinese and Caucasian population identifies ethnic-associated differential transcript abundance of heterogeneous nuclear ribonucleoprotein K (hnRNPK).

Abstract:

:Gene expression variations (GEV) among different ethnic groups have been a subject matter for extensive study. Relatively less known is the extent of alternative splicing variations (ASV) in the context of ethnicity. We conducted a transcriptome sequencing study of 20 lymphoblastoid cell lines obtained from Caucasian and Han Chinese, and identified known genes that exhibit differential isoform abundance between the two ethnic groups. Among them hnRNPK, a co-factor of p53 (TP53), could be further replicated in a 39-sample cohort with TaqMan assay. Although within-population novel splice variants are common, inter-population novel splice variants are rare. We further analyzed 5.63 billion sequencing reads retrieved from the NCBI Sequence Read Archive and identified potential ethnic-specific transcribed regions.

  • Analysis of expressed sequence tags from a fetal human heart cDNA library.

    abstract::Single-pass sequencing of randomly selected cDNA clones to generate expressed sequence tags (ESTs) has been widely used to identify novel genes and to study gene expression in a variety of tissues. We have generated 2244 ESTs from a human fetal heart library (GenBank Accession Nos. R30692-30774 and R56965-58824), whic...
