Abstract

Ribosomal proteins (RPs) play pivotal roles in developmental regulation. The loss or mutation of ribosomal protein L11 (RPL11) induces various developmental defects. However, few RPs have been functionally characterized in Apis cerana cerana. In this study, we isolated a single copy gene, AccRPL11, and characterized its connection to brain maturation. AccRPL11 expression was highly concentrated in the adult brain and was significantly induced by abiotic stresses such as pesticides and heavy metals. Immunofluorescence assays demonstrated that AccRPL11 was localized to the medulla, lobula and surrounding tissues of esophagus in the brain. The post-transcriptional knockdown of AccRPL11 gene expression resulted in a severe decrease in adult brain than in other tissues. The expression levels of other brain development-related genes, p38, ERK2, CacyBP and CREB, were also reduced. Immunofluorescence signal attenuation was also observed in AccRPL11-rich regions of the brain in dsAccRPL11-injected honeybees. Taken together, these results suggest that AccRPL11 may be functional in brain maturation in honeybee adults.

Structural and copy number analysis of the genomic sequences of AccRPL11. Intron-exon structure of the RPL11 gene from Mus musculus (MmRPL11, Genbank ID: NC_000070.5), Nasonia vitripennis (NvRPL11, Genbank ID: NW_001820126.1), Apis mellifera (AmRPL11, Genbank ID: NC_007071.3) and A. cerana cerana (AccRPL11, Genbank ID: JN699055). Exons are indicated with white box and introns are shown by lines. UTRs are displayed with black box in this alignment. Lengths of the exons are marked according to the scale above. (JPEG 31 kb)

Overexpression and western blot analysis of AccRPL11. (a) Expression and purification of AccRPL11 protein using SDS-PAGE. Lanes 1: and 2: uninduced expression of recombinant AccRPL11 protein; lanes 3 and 4: overexpression of recombinant AccRPL11 protein after IPTG induction; lane 5: purified recombinant AccRPL11 protein and lane M: protein molecular weight marker. AccRPL11 is indicated by an arrowhead. (b) The anti-AccRPL11 specificity was evaluated using immunoblot analysis (left) and ponceau staining (right). The ponceau staining verified that similar amounts of protein were loaded in each lane. Lane 1: induced recombinant AccRPL11 protein; lane 2: purified recombinant AccRPL11 protein; and lane M: pre-stained protein molecular weight marker. (JPEG 12 kb)
