Overview of Gene Research
Akap8l, a member of the A kinase anchor-protein (AKAPs) family, is involved in multiple biological functions. It interacts with mTORC1 in the cytoplasm, and this interaction is associated with processes like translation, cell growth, and cell proliferation [4]. Additionally, it may anchor protein kinase A (PKA) through regulatory subunit Iα, suggesting a multifaceted role in cellular regulation.
In diabetes-associated cognitive impairment (DACI), Akap8l has been identified as a key mediator. In high-glucose (HG)-treated microglia, Akap8l is significantly upregulated, and its accumulation is specific to microglia. In streptozotocin (STZ)-induced diabetic mice, both Akap8l knockdown and rapamycin treatment enhanced cognitive function, reduced microglial activation, suppressed mTORC1 signaling, normalized autophagic flux, mitigated neuroinflammation, and decreased pyroptosis. This indicates that Akap8l, by interacting with mTORC1, obstructs autophagic processes and triggers neuroinflammatory responses in DACI [1].
In cancer research, high Akap8l expression is associated with poor prognosis in esophageal squamous cell carcinoma (ESCC), and it can be considered an independent risk factor. High expression is related to lymph node metastasis and lymph node stage in ESCC patients [2]. In gastric cancer, Akap8l enhances cell stemness and chemoresistance by stabilizing SCD1 mRNA in an IGF2BP1-dependent manner, and it may represent a novel therapeutic target to overcome chemoresistance [3].
In conclusion, Akap8l plays crucial roles in various biological processes and disease conditions. In DACI, it is a key mediator affecting autophagy and neuroinflammation through its interaction with mTORC1. In cancer, especially in ESCC and gastric cancer, its high expression is associated with poor prognosis and enhanced cancer-related phenotypes. Research on Akap8l, especially through gene-knockout or conditional-knockout mouse models, provides valuable insights into the underlying mechanisms of these diseases, potentially guiding the development of new therapeutic strategies.
