PTGDS and breast carcinoma: The correlation network results showed that Anxa1 is involved in vascular processes in the circulatory system, rhythmic processes, enzyme inhibitor activity, and fatty acid derivative transport via interactions with Ocln, Cbs, Ptgds, Pkia, Prok2, Gja1, Kcnma1, Oaz3, and Oxt(Figure 8G). In addition, two upregulated hub DEGs, Plin1 and Oxt, were positively correlated with Anxa1 expression in breast cancer patients (Figure S15A-B).
