Abstract:

The present study has taken advantage of publicly available cell type specific mRNA expression databases in order to identify potential genes participating in the development of retinal AII amacrine cells. We profile two such genes, Delta/Notch-like EGF repeat containing (Dner) and nuclear factor I/A (Nfia), that are each heavily expressed in AII amacrine cells in the mature mouse retina, and which conjointly identify this retinal cell population in its entirety when using antibodies to DNER and NFIA. DNER is present on the plasma membrane, while NFIA is confined to the nucleus, consistent with known functions of each of these two proteins. DNER also identifies some other subsets of retinal ganglion and amacrine cell types, along with horizontal cells, while NFIA identifies a subset of bipolar cells as well as Muller glia and astrocytes. During early postnatal development, NFIA labels astrocytes on the day of birth, AII amacrine cells at postnatal (P) day 5, and Muller glia by P10, when horizontal cells also transiently exhibit NFIA immunofluorescence. DNER, by contrast, is present in ganglion and amacrine cells on P1, also labeling the horizontal cells by P10. Developing AII amacrine cells exhibit accumulating DNER labeling at the dendritic stalk, labeling that becomes progressively conspicuous by P10, as it is in maturity. This developmental time course is consistent with a prospective role for each gene in the differentiation of AII amacrine cells.

Regulatory connection between the expression level of classical protein kinase C and pruning of climbing fibers from cerebellar Purkinje cells.

Abstract:

Cerebellar Purkinje cells (PCs) express two members of the classical protein kinase C (cPKC) subfamily, namely, PKCα and PKCγ. Previous studies on PKCγ knockout (KO) mice have revealed a critical role of PKCγ in the pruning of climbing fibers (CFs) from PCs during development. The question remains as to why only PKCγ and not PKCα is involved in CF synapse elimination from PCs. To address this question, we assessed the expression levels of PKCγ and PKCα in wild-type (WT) and PKCγ KO PCs using PC-specific quantitative real-time reverse transcription-polymerase chain reaction, western blotting, and immunohistochemical analysis. The results revealed that the vast majority of cPKCs in PCs were PKCγ, whereas PKCα accounted for the remaining minimal fraction. The amount of PKCα was not up-regulated in PKCγ KO PCs. Lentiviral expression of PKCα in PKCγ KO PCs resulted in a 10-times increase in the amount of PKCα mRNA in the PKCγ KO PCs, compared to that in WT PCs. Our quantification showed that the expression levels of cPKC mRNA in PKCγ KO PCs increased roughly from 1% to 22% of that in WT PCs solely through PKCα expression. The up-regulation of PKCα in PKCγ KO PCs significantly rescued the impaired CF synapse elimination. Although both PKCα and PKCγ are capable of pruning supernumerary CF synapses from developing PCs, these results suggest that the expression levels of cPKCs in PKCγ KO PCs are too low for CF pruning.
