Among the samples from transcriptome analysis, PER1 was the most downregulated TSG in the Indian cohort except for serous cystadenoma and from literature, its levels correlate with infiltrating neutrophils, regulatory T cells, and M2 macrophages (Chen et al., 2021), which was evident in the Indian cohort (Figure 3L). Here, PER1 is linked to serous cystadenoma.
