HIPSTR lncRNA knockdown in HEK293 cells

ABSTRACT: HIPSTR is a conserved lncRNA that is transcribed antisense to TFAP2A gene. Unlike previously reported antisense lncRNAs, HIPSTR expression does not correlate with the expression of its antisense counterpart. HIPSTR depletion in HEK293 and H1BP cells predominantly affects genes involved in early organismal development and cell differentiation.

HIPSTR lncRNA knockdown in HEK293 cells

Project description:HIPSTR is a conserved lncRNA that is transcribed antisense to TFAP2A gene. Unlike previously reported antisense lncRNAs, HIPSTR expression does not correlate with the expression of its antisense counterpart. HIPSTR depletion in HEK293 and H1BP cells predominantly affects genes involved in early organismal development and cell differentiation. HEK293 cells were transfected with antisense oligonucleotides (ASOs) targeting HIPSTR (ASO #1 or ASO #2) or control scrambled ASO (ASO CTL); transfection with each ASO was done in triplicate.

HIPSTR lncRNA knockdown in HEK293 and H1BP cells

Project description:Compared to mRNAs, lncRNAs display higher developmental stage-, tissue-, and cell-subtype-specificity of expression, and are generally less abundant in a population of cells. Here, we identify HIPSTR (Heterogeneously expressed from the Intronic Plus Strand of the TFAP2A-locus RNA), a novel lncRNA gene in the developmentally regulated TFAP2A locus. HIPSTR has evolutionarily conserved expression patterns, its promoter is most active in undifferentiated cells, and depletion of HIPSTR in HEK293 and in pluripotent H1BP cells predominantly affects the genes involved in early organismal development and cell differentiation. HIPSTR is specifically induced and heterogeneously expressed in the 8-cell-stage human embryos during the major wave of embryonic genome activation. We systematically explore the phenomenon of cell-to-cell variation of gene expression and link it to low population-level expression of lncRNAs, showing that, similar to HIPSTR, the expression of thousands of lncRNAs is more highly heterogeneous than the expression of mRNAs in the individual, otherwise indistinguishable cells of totipotent human embryos, primordial germ cells, and stable cell lines. In these series of microarray experiments we evaluate genome-wide gene expression changes after knockdown of HIPSTR lncRNA in HEK293 and H1BP cells. Refer to individual Series
