Critical contribution of 3’ non-seed base pairing to the in vivo function of the evolutionarily conserved let-7a microRNA [RNA-seq]

ABSTRACT: The C.elegans transcriptomes of single-nt let-7a 3' non-seed mutants (U13A / U18A). In order to identified gene perturbance and determine the post-transcriptional regulation mechanism caused by disrupting 3' non-seed pairing of let-7a, we examined the global gene expression by RNAseq in addition to ribosome profiling of L4 whole animals. To include the deadenylated but temperally stable mRNA in the enrichment, we used a RNase H based ribosomal RNA depletion with antisense oligos specifically designed for C.elegans to enrich mRNA (PMID: 33005886). lin-41(ma480) was used in the background to filter out downstream regulation related to the lin-41 pathway.

Critical contribution of 3’ non-seed base pairing to the in vivo function of the evolutionarily conserved let-7a microRNA [Ribo-seq]

Project description:The C.elegans translatomes of single-nt let-7a 3' non-seed mutants (U13A / U18A). In order to identified gene perturbance caused by disrupting 3' non-seed pairing of let-7a, we examined the global gene expression at tranlational levels of L4 whole animals by ribosome profiling. We found that let-7a U13A mutation results in overexpression135/351 Note for let-7a U13A mutation, lin-41(ma480) was used in the background to filter out downstream regulation related to the lin-41 pathway.

Critical contribution of 3’ non-seed base pairing to the in vivo function of the evolutionarily conserved let-7a microRNA [miRNA-seq]

Project description:Small RNA sequencing of all the let-7a single-nucleotide mutants to confirm the expression of the mutant miRNAs.We found that the abundance of the mutated let-7a miRNA in each mutant was similar to that of the native let-7a in WT, with a variance (<10%) that we judge not sufficient to cause lf phenotypes by reduced expression (Fig. 3B). Note that the strains with mutations at g11-g16 also contained a WT let-7 allele on a genetic balancer umnIs25(mnDp1), hence both WT and mutant let-7a were expressed.

LIN-41 RIP-Seq

Project description:FLAG-GFP tagged LIN-41 was immunoprecipitated using FLAG dynabeads (Sigma) from lysates of young adult C.elegans. After washing steps, bound fraction (IP) was eluted from beads and associated RNAs were isolated by using the Pico pure RNA isloation kit (Invitrogen)

OMA-1, LIN-41 IPMS - LIN-41 and OMA Ribonucleoprotein Complexes Mediate a Translational Repression-to-Activation Switch Controlling Oocyte Meiotic Maturation and the Oocyte-to-Embryo Transition in Caenorhabditis elegans

Project description:An extended meiotic prophase is a hallmark of oogenesis. Hormonal signaling activates the CDK1/cyclin B kinase to promote oocyte meiotic maturation, which involves nuclear and cytoplasmic events. Nuclear maturation encompasses nuclear envelope breakdown, meiotic spindle assembly, and chromosome segregation. Cytoplasmic maturation involves major changes in oocyte protein translation and cytoplasmic organelles and is poorly understood. In the nematode Caenorhabditis elegans, sperm release the major sperm protein (MSP) hormone to promote oocyte growth and meiotic maturation. Large translational regulatory ribonucleoprotein (RNP) complexes containing the RNA-binding proteins OMA-1, OMA-2, and LIN-41 regulate meiotic maturation downstream of MSP signaling. To understand the control of translation during meiotic maturation, we purified LIN-41-containing RNPs and characterized their protein and RNA components. Protein constituents of LIN-41 RNPs include essential RNA-binding proteins, the GLD-2 cytoplasmic poly(A) polymerase, the CCR4-NOT deadenylase complex, and translation initiation factors. RNA sequencing defined mRNAs associated with both LIN-41 and OMA-1, as well as sets of mRNAs associated with either LIN-41 or OMA-1. Genetic and genomic evidence suggests that GLD-2, which is a component of LIN-41 RNPs, stimulates the efficient translation of many LIN-41-associated transcripts. We analyzed the translational regulation of two transcripts specifically associated with LIN-41 that encode the RNA regulators SPN-4 and MEG-1. We found that LIN-41 represses translation of spn-4 and meg-1, whereas OMA-1 and OMA-2 promote their expression. Upon their synthesis, SPN-4 and MEG-1 assemble into LIN-41 RNPs prior to their functions in the embryo. This study defines a translational repression-to-activation switch as a key element of cytoplasmic maturation.
