Background:
Recent studies have shown that curcumin can reduce the symptoms of hydrocephalus. However, the underlying mechanisms remain unclear. Our previous studies demonstrated that E2F transcription factor 4 (E2F4) protein plays an important role in hydrocephalus; hence, we hypothesized that E2F4 may involve in curcumin mediated anti-hydrocephalus benefits.
Methods:
E2F4 expression and functions in different human tissues and cell lines were determined and analyzed using the all RNA-seq and ChIP-seq sample and signature search database and ChIP-atlas database. Hydrocephalus mouse model was established through stereotactic injection of shE2F4 into frontal cortex. Mice were treated with curcumin, and then hydrocephalus severity, the expression of E2F4, and downstream targets were analyzed.
Results:
E2F4 was highly expressed in the nervous system, which was downregulated in the bran of hydrocephalus patients. Knockdown E2F4 in mice could mimic the phenotype of human hydrocephalus. Upon curcumin administration, E2F4 expression level was increased, and the hydrocephalus severity score was significantly decreased in mouse model. Mechanistically, curcumin attenuated hydrocephalus through activating E2F4 signaling pathway.
Conclusion:
Curcumin suppresses hydrocephalus progression via activation of E2F4, which could be a target for hydrocephalus treatment.
