In addition, qRT-PCR and western blotting indicated that compared with the NC group, the mRNA and protein levels of MYLK, MYL9, MYH11, CALD1, ACTA2, SPP1, and CNN1 were differentially expressed in the PCa group, which is consistent with the analysis results of GEO datasets. Here, MYL9 is linked to posterior cortical atrophy.
