Basics

• Stem cells

Page 5: Reprogramming of differentiated cells  into  stem cells or other somatic cells

• Transcriptionfactors

Aktivator

Bindung an Enhancer

Verstärkung der Transkription

Bindung an Operator

Stabilisation der RNS-

Polymerase

Bindung an Coaktivator

Verstärkung der Transkription

Katalysation der Acetylierung

Offenere DNS = Hochregulation

Repressor

Bindung an Operator

Verhindern der Transkription

Bindung an Corepressor

Abregulierung der Transkription

Katalysieren der Deacetylierung

Engere DNS = Verminderung

der Transkription

Bindung an einen Silencer

Herabregulation der Transkription
