Sorcin induces gastric tumor cell migration and invasion; sorcin silencing downregulates the expression of cathepsin Z, matrix metalloproteinases 2 and 9 (MMP2 and MMP9), and signal transducer and activator of transcription 3 (STAT3), resulting in the suppression of cancer growth and metastasis [78]. Here, MMP2 is linked to gastric neoplasm.
