Objective:
To study the role of 5' untranslated region (UTR) and intron in the expression of human thrombopoietin (TPO) gene.
Methods:
A number of expression vectors containing TPO mini-gene fused to the regulatory elements of cytomegalovirus (CMV) were constructed and transfected via lipofectin into cultured cos-1 cells for transient expression of TPO gene. The cell culture media were analyzed with highly sensitive sandwich enzyme-linked immunosorbent assay (ELISA) 48 h after the transfection.
Results:
The expression levels of the TPO gene elements followed the order of TPO intron v> TPOcDNA> TPO intron I> TPO intron I> TPO gDNA in cos-1 cells.
Conclusion:
The last intron of TPO gene obviously enhances the expression level of TPO gene, which can be inhibited by 5'UTR of TPO gene.

What is Gene Expression?
Gene expression is the process in which DNA directs the synthesis of functional products, that is, proteins. Cells can regulate gene expression at various stages. It allows organisms to generate different cell types and enables cells to adapt to internal and external factors.

A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is made up of nucleotides and proteins consist of amino...
