Project description:We performed RNA-seq to quantify gene expression changes in adult worms upon knockdown of transcription factor unc-62/Homothorax. unc-62 is a developmental regulator that binds proximal to age-regulated transcripts and modulates lifespan. In the intestine (in which tissue-specific unc-62 knockdown increases lifespan), we identify multiple effects of unc-62 knockdown linked to extension of longevity. First, unc-62 RNAi decreases the expression of yolk proteins (vitellogenins) that aggregate in the body cavity and become toxic in old age. Second, unc-62 RNAi results in a broad increase in expression of intestinal genes that typically decrease expression with age, suggesting that unc-62 activity balances intestinal resource allocation between yolk protein expression and fertility on the one hand and somatic functions on the other. mRNA profiling by Illumina HiSeq of 3 biological replicates of day 4 adult Caenorhabditis elegans that were fed either control or unc-62 RNAi beginning at day 1 of adulthood.

Project description:Polyploid cells contain more than two copies of the genome and are found in many plant and animal tissues. Different types of polyploidy exist, in which the genome is confined to either one nucleus (mononucleation) or two or more nuclei (multinucleation). Despite the widespread occurrence of polyploidy, the functional significance of different types of polyploidy are largely unknown. Here, we assess the function of multinucleation in C. elegans intestinal cells through specific inhibition of binucleation without altering genome ploidy. Through single worm RNA sequencing, we find that binucleation is important for tissue-specific gene expression, most prominently for genes that show a rapid upregulation at the transition from larval development to adulthood. Regulated genes include vitellogenins, which encode yolk proteins that facilitate nutrient transport to the germline. We find that reduced expression of vitellogenins in mononucleated intestinal cells leads to progeny with developmental delays and reduced fitness. Together, our results show that binucleation facilitates rapid upregulation of intestine-specific gene expression during development, independently of genome ploidy, underscoring the importance of spatial genome organization for polyploid cell function.

Project description:The nematode Caenorhabditis elegans exhibits rapid senescence that is promoted by the insulin/IGF-1 signaling (IIS) pathway via regulated processes that are poorly understood. IIS also promotes production of yolk for egg provisioning, which in post-reproductive animals continues, supported by destructive repurposing of intestinal biomass that contributes to senescence. Post-reproductive mothers vent this yolk which can be consumed by larvae and promotes their growth. This implies that later yolk production is not futile; instead vented yolk functions similarly to milk. Moreover, yolk venting is promoted by IIS. That this process is promoted by IIS provides new insights into how and why IIS shortens lifespan in C. elegans. Fully-fed d4 hermaphrodites were allowed to vent for 30 min, and vented proteins analysed against excretory/secretory products collected for L3 larvae as a negative control.
