Figure S5 and Figure Legend Snippet: ESE induces stemness in the murine skin (A) Total study samples: mice skin samples from the Rodent Research-8 mission (also known as Rodent Research Reference-1) were procured from International Space Station (ISS) National. Mice flown in animal enclosure modules on the ISS were classified as Exposure to Space Environment (ESE) group ( n = 17). Ground-based mice (ground controls; n = 18) maintained under similar housing conditions were used as controls. Image created in BioRender. Kanhaiya, K. (2024) https://BioRender.com/q43i834 . (B) To quantify transcriptional differences between the skin of the mice of ESE group ( n = 10) vs. the ground controls ( n = 6), targeted RNA sequencing was performed. A total of 1,498 analysis ready differentially expressed transcripts ( p value < 0.05) were identified using ingenuity pathway analysis (IPA) software. Volcano plot and (C) Venn diagram showing the comparison of differentially expressed genes (DEG) in ESE group skin sample 859 (57.3%) transcripts were upregulated while 639 (42.7%) were downregulated. (D) Canonical pathway enrichment analysis of DEGs, high in ESE group was performed using IPA. Presented canonical pathways were identified as (1) DNA methylation, (2) embryonic stem cell pluripotency, (3) signaling by VEGF, (4) HIF1α signaling, and (5) Sirtuin signaling pathway. (E) Pathway generated by IPA showing the candidate genes involved in the human embryonic stem cell (ESC) pluripotency pathway. Among the biofunctions that were predicted to be upregulated in the skin samples of ESE group were ESC pluripotency, self-renewal of cells, and proliferation of ESC. See also

Figure S4 , Figure Legend Snippet: ESE-induced promoter hypomethylation increased VEGF-mediated angiogenesis pathway in responders (A) Targeted validation of Vegfb gene promoter methylation status in ground control, responder ESE cohort, and non-responder ESE cohort. Genome track showing the Vegfb locus (top). Representative DNA methylation tracks (bottom) show diminished levels of methylated CpGs in responder ESE skin as compared to non-responder ESE or control skin. (B) Venn diagram showing the percentage of hypomethylated (blue) and hypermethylated (red) CpGs in Vegfb gene in responder ESE cohort ( n = 4) vs. ground control ( n = 12) and in (C) non-responder ESE cohort ( n = 6) vs. ground control ( n = 12). (D) To quantify transcriptional differences between the skin of the mice of responder ESE cohort compared to ground controls, targeted RNA sequencing was performed. Upstream regulator prediction analysis of DEGs, high in responder ESE cohort was performed using IPA. The candidates from VEGF Pathway were enriched in responder ESE cohort. See also
