    Abstract Background: Hepatocellular carcinoma (HCC) typically begins inconspicuously and progresses swiftly, leading to most patients being diagnosed at an advanced stage. Accordingly, a pressing priority is to clarify the development mechanisms of HCC and devise efficient intervention and treatment protocols. Methods: An upstream miRNA of solute carrier transporter family 1 member 5 (SLC1A5) was predicted to be miR-122-5p by various databases, and a dual-luciferase reporter gene assay was used to verify the SLC1A5- and miR-122-5p-targeting relationship. SLC1A5 and miR-122-5p expression in HCC cells was quantitatively assessed using quantitative reverse transcription polymerase chain reaction (qRT–PCR). Western blotting… More >

    Abstract Glutamine is one of the most abundant non-essential amino acids in human plasma and plays a crucial role in many biological processes of the human body. Tumor cells take up a large amount of glutamine to meet their rapid proliferation requirements, which is supported by the upregulation of glutamine transporters. Targeted inhibition of glutamine transporters effectively inhibits cell growth and proliferation in tumors. Among all cancers, digestive system malignant tumors (DSMTs) have the highest incidence and mortality rates, and the current therapeutic strategies for DSMTs are mainly surgical resection and chemotherapy. Due to the relatively More > Graphic Abstract
