For example, stemming from the connection of tryptophanyl-tRNA synthetase (TrpRS) to angiostasis and immune regulation [13,14,15], TrpRS expression was measured in various types of cancer, such as oral squamous cell carcinoma [16], gastric cancer [17], and uveal melanoma [18], to determine its value as a cancer marker. Here, WARS1 is linked to cancer.
