| Abstract |
Lead exposure can cause cognitive dysfunction in children, thus it still raises important public health concerns in China and other countries. However, the underlying molecular mechanisms are still not well defined. In this study, we aimed to elucidate the mechanisms underlying lead neurotoxicity by focusing on alterations of synaptic proteins in the mouse hippocampus at the early life. Mother mice and their offspring were exposed to 0, 0.5, 1.0, and 2.0 g/L lead via drinking water from the first day of gestation until postnatal day (PND) 40. Synaptic ultrastructure and expressions of postsynaptic density protein-95 (PSD-95), neuronal nitric oxide synthase (nNOS) and synaptophysin (SYP) at both protein and gene levels in the hippocampus were analyzed. The results revealed that developmental lead exposure caused a diminished postsynaptic density in the hippocampus. Moreover, the protein levels of PSD-95, nNOS, and SYP decreased significantly due to developmental lead exposure. On the other hand, the messenger RNA (mRNA) levels of PSD-95 and SYP decreased significantly in PND 40 mice exposed to lead. Collectively, developmental lead exposure might result in decreased protein and gene expressions of both presynaptic and postsynaptic proteins. Our findings raised a possibility that alterations of synaptic proteins in the hippocampus induced by lead exposure at the early life might serve an important role for the subsequent intellectual impairments, e.g., deficits in spatial learning and memory ability at later ages shown in our recently published paper. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 15 December 2015.
All research outputs
#20,298,249
of 22,835,198 outputs
Outputs from Molecular Neurobiology
#2,793
of 3,458 outputs
Outputs of similar age
#326,629
of 389,181 outputs
Outputs of similar age from Molecular Neurobiology
#124
of 161 outputs
Altmetric has tracked 22,835,198 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 3,458 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.2. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 389,181 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 161 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
