Core Tip
Core tip: Gastric cancer (GC) is one of the most common types of cancer. The molecular mechanism of GC is intricate, and understanding the molecular mechanism of drug resistance is helpful for improving the efficacy of chemotherapy. The mutual binding of miRNAs and transcription factors is closely related to cancer occurrence. In this study, we found that E2F transcription factor 1 inhibited miR-34c transcription to both promote GC cell proliferation as well as enhance the resistance of paclitaxel combined with cisplatin. Therefore, silencing the expression of E2F transcription factor 1 in GC cells could improve the efficacy of paclitaxel combined with cisplatin.
