Translation profiling by array of H1 human embryonic stem cells induced to differentiate into the trophoblast lineage in order to perform polysome analysis


ABSTRACT: H1s are induced to differentiate into the trophoblast (TE) lineage, and polysome analysis performed at 0hr (Undifferentiated), 12hr TE and 24hr TE. The whole cell extract (WCE) is a cytoplasmic lysate of the cell . G1-G4 represent RNAs that were found in different fractions of a sucrose gradient, which represents monosomes, polysomes, etc. Thus the WCE is used as the denominator so that for a particular transcript, we can express G1, for example, as a fraction of the total RNA.

LIN28 function is fundamental to the activity and behavior of human embryonic stem cells (hESCs) and induced pluripotent stem cells. Its main roles in these cell types are the regulation of translational efficiency and let-7 miRNA maturation. However, LIN28-associated mRNA cargo shifting and resultant regulation of translational efficiency upon the initiation of differentiation remain unknown. An RNA-immunoprecipitation and microarray analysis protocol, eRIP, that has high specificity and sensit  ...[more]
