Abstract
The trim14 (pub, KIAA0129) gene encodes the TRIM14 protein which is a member of the tripartite motif (TRIM) family. Previously, we revealed high expression levels of trim14 in HIV- or SIV-associated lymphomas and demonstrated the influence of trim14 on mesodermal differentiation of mouse embryonic stem cells (mESC). In the present work, to elucidate the role of trim14 in normal and pathological processes in the cell, we used two different types of cells transfected with trim14: mESC and human HEK293. Using subtractive hybridization and real-time PCR, we found a number of genes which expression was elevated in trim14-transfected mESC: hsp90ab1, prr13, pu.1, tnfrsf13c (baff-r), tnfrsf13b (taci), hlx1, hbp1, junb, and pdgfrb. A further analysis of the trim14-transfected mESC at the initial stage of differentiation (embryoid bodies (EB) formation) showed essential changes in the expression of these upregulated genes. The transfection of trim14 into HEK293 also induced an enhanced expression of the several genes upregulated in trim14-transfected mESC (hsp90ab1, prr13, pu.1, tnfrsf13c (baff-r), tnfrsf13b (taci), and hlx1). Summarizing, we found similar genes that participated in trim14-directed processes both in mESC and in HEK293. These results demonstrate the presence of the similar mechanism of trim14 gene action in different types of mammalian cells.Entities:
