Abstract

Background: Hepatocellular carcinoma (HCC) is one of the most common malignancies with high invasion and metastasis capacities. Circular RNAs (circRNAs) were evidenced to take part in the progression of multifarious cancers, including HCC. However, the role of circ_0091579 in HCC progression has not been fully described. This study aimed to explore the function of circ_0091579 and its potential regulatory mechanism in the progression of HCC. Materials and Methods: The expression of circ_0091579, microRNA-490-5p (miR-490-5p), and cancer susceptibility candidate 3 (CASC3) in HCC tissues and cells was detected by quantitative real-time polymerase chain reaction. The circular characteristic and stability of circ_0091579 were verified by RNase R digestion and actinomycin D reaction assays. Cell proliferation, migration, and invasion were determined by methyl thiazolyl tetrazolium assay and Transwell assay, respectively. The level of glycolysis was evaluated by glucose consumption and lactate production. The levels of proteins were examined by Western blot. The interaction between miR-490-5p and circ_0091579 or CASC3 was certified by Dual-luciferase reporter assay. Results: circ_0091579 and CASC3 were upregulated, while miR-490-...Continue Reading

Cancer Metabolic Reprogramming (Keystone)

Cancer metabolic reprogramming is important for the rapid growth and proliferation of cancer cells. Cancer cells have the ability to change their metabolic demands depending on their environment, regulated by the activation of oncogenes or loss of tumor suppressor genes. Here is the latest research on cancer metabolic reprogramming.

Cell Migration

Cell migration is involved in a variety of physiological and pathological processes such as embryonic development, cancer metastasis, blood vessel formation and remoulding, tissue regeneration, immune surveillance and inflammation. Here is the latest research.
