Subsequent, we handled cells with distinct concentrations of NAD+. When extra for 24 h at eighty µM in HeLa and 400 µM in U2OS cells, NAD+ impaired the incorporation of EdU (Fig. 2a and Extended Data Fig. 1k,l). Moreover, 16 µM of NAD+ was enough to scale back fork speed by ~40% in HeLa https://emersonb222mxh4.pennywiki.com/user
