The effect of chronic alcohol exposure on spatial memory and BDNF-TrkB- PLCγ1 signaling in the hippocampus of male and female mice.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Alcohol is a commonly used drug worldwide, and abuse of alcohol has become a serious public health problem. Alcohol consumption over time can cause cognitive deficits and memory impairment, which is thought to be associated with changes in the hippocampus. Given previously known effects of brain-derived neurotrophic factor (BDNF) in regulating synaptic plasticity and learning and memory, we investigated the effect of chronic alcohol consumption on spatial memory impairment in both sexes and changes in BDNF signaling in the hippocampus. After 4 weeks of intermittent access to 20% alcohol, memory impairment in both male and female mice was evaluated using the Morris water maze and the expression of BDNF, TrkB, phosphorylation of PLCγ1 (p-PLCγ1) and PLCγ1 in the hippocampus was examined using Western blot. As expected, females spent longer escape latencies during the training phase, and both sexes spent shorter time in the target quadrant. Furthermore, after 4 weeks 20% alcohol exposure, we found significantly decreased expression levels of BDNF in the hippocampus of female mice but increased levels in male mice. TrkB and PLCγ1 expression showed no significant change in the hippocampus of both sexes. These findings suggest that chronic alcohol exposure may induce spatial memory impairment in both sexes and opposite changes in expression of BDNF and p-PLCγ1 in the hippocampus of males and females.
