RANGAP1 and gastric cancer: Circ‐RanGAP1, which promotes GC invasion and metastasis through the miR‐877‐3p/VEGFA axis, has also been utilized as a biomarker for GC.[39] This circRNA has been found to be upregulated in plasma exosomes obtained from GC patients and was strongly associated with advanced TNM stages and increased mortality in GC.
