Description
PLCβ4 is identified as the critical protein driving male-specific cognitive deficits, yet the mechanism by which cadmium selectively increases PLCβ4 in males is not explained. This represents a key gap in understanding the initiating molecular events of sex-specific neurotoxicity.
Gap type: unexplained_observation Source paper: PLCβ4 driven by cadmium-exposure during gestation and lactation contributes to cognitive deficits by suppressing PIP2/PLCγ1/CREB/BDNF signaling pathway in male offspring. (None, None, PMID:38820747)
