Abstract:
Half of the human genome is composed of repeated DNA, and some types are mobile within our genome (transposons and retrotransposons). Despite their abundance, only a small fraction of them are currently active in our genome (Long Interspersed Element-1 (LINE-1), Alu, and SVA elements). LINE-1 or L1 elements are a family of active non-LTR retrotransposons, the ongoing mobilization of which still impacts our genome. As selfish DNA elements, L1 activity is more prominent in early human development, where new insertions would be transmitted to the progeny. Here, we describe the conventional methods aimed to determine the expression level of LINE-1 elements in pluripotent human cells.

Chromatin Modification in iPS Cells
Compact chromatin makes reprogramming difficult. Enzymes, such as histone demethylases and acetyltransferases, are often added during reprogramming to loosen the chromatin, making the DNA more accessible to transcription factors. Molecules that inhibit histone...

Combinatorial Gene Control
The expression of more than 30,000 genes is controlled by approximately 2000-3000 transcription factors. This is possible because a single transcription factor can recognize more than one regulatory sequence. The specificity in gene...
