ATR and cancer: Plexin domain containing 1 (PLXDC1) also contributes to capillary morphogenesis, and PLXDC1 is highly expressed in various cancers, such as colorectal, lung, pancreas, breast, brain, and osteogenic cancer.[86, 87] Anthrax toxin receptor (ATR) participates in cell‐to‐cell and cell‐to‐extracellular matrix communications, helping the adhesion and migration of cells.[88] The high expression of ATR is proven in various cancers, such as breast, gallbladder, and colorectal cancer; the high expression of ATR is usually associated with shorter survival periods.[89]
