In keloid fibroblasts under hypoxic conditions, our previous research showed reduced glucose metabolism and enhanced phosphorylation of the PI3K/AKT pathway. However, it is unclear if the PI3K/AKT pathway promotes KFb cell function by regulating glucose metabolism under hypoxic conditions. In addition, cell proliferation was impaired when KFb were treated with both SC79 and 2-deoxy-d-glucose, relative to the SC79 group. Our findings showed that the PI3K/AKT pathway promotes proliferation and arrests apoptosis in KFb under hypoxia by regulating glycolysis, reducing glycolysis, indicating that the PI3K/AKT signalling pathway may be a therapeutic target for keloids.
