microRNAs (miRs) are a class of small non-coding RNAs that have been demonstrated to have a crucial role in tumorigenesis of human cancers, including gastric cancer (GC). Previous results have established that miR-100 participated in the development of GC; however, the underlying mechanism remains largely unknown. The preesent study utilized reverse transcription-quantitative polymerase chain reaction to analyze the expression of miR-100 in GC tissues and adjacent normal tissues. The present results indicated that the expression of miR-100 was downregulated in GC tissues when compared to the adjacent normal tissues. Furthermore, low miR-100 expression was observed to be associated with lymph node metastasis, tumor diameter and tumor stage. In addition, Kaplan-Meier analysis revealed that patients with low miR-100 expression tended to have a shorter overall survival. The miR-100 was further identified as an independent prognostic factor for overall survival. Notably, the levels of chemokine (CXC motif) receptor 7 (CXCR7) were inversely correlated with miR-100 in GC cell lines. Furthermore, miR-100 overexpression or CXCR7 depletion decreased in vitro GC cell proliferation. Bioinformatics analysis indicated that miR-100 may bind to the 3'-untranslated region of CXCR7 to prevent the initiation of protein translation. Thus, miR-100 may function as a tumor suppressor in GC, partly by regulating the expression of CXCR7, and the regulation of miR-100 expression may be a potential strategy for the treatment of GC patients.
