CHRDL1 and breast carcinoma: The most highly upregulated genes included the BMP4 antagonist CHRDL1, which mitigates migration and invasion of breast cancer cells (Cyr-Depauw et al., 2016), the secretory leukocyte peptidase inhibitor SLPI, which plays a role in host defense (Majchrzak-Gorecka et al., 2016) and a calcium channel involved in cell signaling (TRPC4), which promotes vessel relaxation and permeability (Freichel et al., 2004).
