Dataset Summary
TitleSubregion-specific proteomic signature in the hippocampus for memory formation in adult mice
DescriptionThe hippocampal formation is a brain structure essential for higher-order cognitive functions. It has exquisite differences in anatomical organization and cellular composition, and hippocampal sub-regions have different properties and functional roles. Areas CA1 and CA3 in particular, are key sub-regions for learning and memory formation that fulfill complementary but specific functions. The molecular basis for such specific properties and the link to learning and memory remain unknown. Here using a SWATH-MS proteomic approach and bioinformatic tools, we identify a selective proteomic signature in area CA1 and CA3, and reveal their specific dynamics during memory formation. We show that 30% of all quantifiable proteins are differentially expressed in area CA1 and CA3 at baseline, and that each proteome responds differently during the formation of memory for object or object location. Using clustering and cross-correlational analyses, we outline specific temporal proteomic profiles and an increased correlation between both forms of memory within area CA1, but not within area CA3. These results provide new insight into a proteomic basis for hippocampal sub-region molecular and functional specificity.
