Figure Lengend Snippet: Differential expressions of MMR genes in iPSC-derived neuronal cells and their regulation by TDP43. ( A ) WB images and histogram illustrate a quantitative comparison of MMR expression in control and siTDP43-treated human iPSC-derived neural lineage progenitor stem cells (NPSCs). Quantitation of protein levels normalized to that of GAPDH. ( B ) Schematic of iPSC, NPSC, and terminally differentiated motor neurons (iMN) utilized in this study. ( C ) IF images revealing the expression of TDP43; and MLH1, MSH2, MSH3, MSH6, and PMS2, and nuclear DNA (DAPI) after siTDP43-mediated KD of TDP43 in iPSC-derived iMNs. ( D ) WB images show the expression of select MMR factors across the following states of cellular differentiation: iPSC, NPSC, and iMN. Error bars indicate mean ± SEM from three independent experiments. Significance values (P-values) are as follows P > 0.5 (ns), P <0.5 (*), P <0.001 (***) and P <0.0001 (****).
Article Snippet: Terminally differentiated neurons were derived from neural progenitor stem cells (NPSCs) (Jackson Lab) WT (JIPSC1000), TDP43-Q331K (JIPSC1066), TDP43-A315T, and TDP43-M337V, according to established methods [ ].
