Downregulation of Transketolase Activity Is Related to Inhibition of Hippocampal Progenitor Cell Proliferation Induced by Thiamine Deficiency

Figure 3

Inhibition of the proliferation of HPCs by oxythiamine. The number of neurospheres significantly decreased in a dose-dependent manner in HPCs treated with >5 μM/L oxythiamine ((a1)–(a5), (c)), and the proportion of small neurospheres was in direct proportion to the oxythiamine dose (d). The OD values generated by the CCK-8 assay of HPCs treated with oxythiamine at doses >5 μM/L were significantly lower than those of the 0 μM/L group (b). Scale = 100 μm.
