FOXD2 and ischemic stroke: So we further verified the expression level and the m6A modification level of LncRNA FOXD2-AS1 in another 12 patients with ischemic stroke and found that the results were indeed consistent with the trend of the sequencing, and with the increase of sample size, the expression level of LncRNA FOXD2-AS1 was correlated with methylation level (Figure 2(f)).
