In order to determine the generalizability of MTP18′s role in chemotherapy induced mitochondrial fission and apoptosis in gastric cancer, we included additional experiments using Fluorouracil (5-FU), which is considered a first line chemotherapeutic agent for advanced gastrointestinal cancers [37, 38], and tested its effects in an additional gastric cancer NCI-N87 cell line. Here, MTFP1 is linked to gastric cancer.
