Although hsa-miR-873-5p and GDF15 levels appeared to be negatively correlated in our in vitro assays, elevated hsa-miR-873-5p or GDF15 levels have been previously associated with different stages of cancer-like cell proliferation [48–50], metastasis [49, 51, 52], and chemoresistance [47, 53–55]. The gene discussed is GDF15; the disease is cancer.
