WOP159 C.elegans ahcy?1(syb784 *syb646[ahcy?1(Y145C)::GFP]) I. Show Description
Engineered Y145C substitution mutation in endogenously GFP-tagged ahcy-1 locus. ahcy-1(Y145C) mutation mimics the pathogenic human mutation AHCY Y143C. ahcy-1(Y145C) mutants have a prolonged lifespan and are larger than control animals. ahcy-1(Y145C) mutants are fertile and produce a brood of laid and hatched eggs similar to control animals. ahcy-1(Y145C) mutants show a slight increase in SAH and a decrease in SAM levels, leading to an increased SAH to SAM ratio. See WOP122 for control strain. Derived by out-crossing parental strain PHX784 two times to N2. Reference: Thapa P, et al. NPJ Aging. 2023 Dec 5;9(1):27. doi: 10.1038/s41514-023-00125-1. PMID: 38052822.
XA4900 C. elegans rib-2(qa4900)/qC1 [dpy-19(e1259) glp-1(q339) III. Show Description
Heterozygotes are WT and segregate WT and Sterile Dpys. Homozygous rib-2(qa4900) animals give homozygous F2 animals that can develop to the adult stage but exhibit abnormal phenotypes such as egg-laying defects, increased body width, and reduced activity in movement. While the F2 qa4900 homozygotes are fertile, the F3 qa4900 homozygous progeny stop developing during gastrulation and fail to develop normally. 511 bp deletion in the region of intron2 to exon 6 of the rib-2 gene (K01G5.6).
XA8400 C. elegans qaIs8400. Show Description
qaIs8400 [let-858p::Ov-GST-3 + rol-6(su1006)]. Called AK1 in the reference article. The Ov-GST-3 gene was amplified from genomic DNA of O. volvulus with 1µM of the sequence specific primer 5'Klon and 3'Klon (5'Klon: 5'-GGCGTACGATGTCAAGATTTCCTCAACAAG-3'; 3'Klon: 5'-GGTCTAGATTTATTTAGGAATGATTGAATCGGTCG-3'; representing bases 4 - 25 and the complementary sequence of bases 821 - 841 of the published Ov-GST-3 cDNA (AF203814); bold underlines indicate restriction sites for Pfl23II (SplI) and XbaI, respectively; dotted underline indicates the start codon for translation; italics indicates the conserved sequence for the polyadenylation signal for transgenic transcript processing; the 8 5'-nucleotides of primer 3'Klon and the fourteen 5'-nucleotides of primer 5'Klon do not correspond to the template and introduce the sequences to the amplicon), 200 µM of each deoxynucleotide (Gibco BRL) and 2.5 units of Taq polymerase (Gibco BRL). After an initial denaturation of 3 minutes at 93°C, 35 cycles of annealing at 55°C for 1 minute, synthesis at 72°C for 2 minutes and a 1 minute denaturation at 93°C were performed, followed by a final extension at 72°C for 5 minutes. The genomic Ov-GST-3 fragment obtained by PCR (see above) was ligated into the pGEM-T Easy vector (Promega) by TA-cloning, cleaved with the restriction enzymes Pfl23II (SplI) and XbaI (restriction sites introduced by the primer) and inserted between the unique Pfl23II (SplI) and XbaI sites of the vector pPD103.05 (kindly provided by A. Fire). The sequence of the genomic Ov-GST-3 fragment in the resulting plasmid pAK1 was confirmed by automated dye terminator, dideoxy sequencing (ABI Prism 377TM Sequencer, PE Applied Biosystems) using the PCR primers (see above). The pAK1 DNA was injected in combination with the marker plasmid pRF4 [rol-6(su1006)] into the gonads of N2 C. elegans at a concentration of approximately 100 ng/µl for each plasmid. Transgenic worms were identified by the selectable Roller marker phenotype and the stable transmitting line AK1ex (AK1 extrachromosomal) was established. Integration of the extrachromosomal arrays was achieved by irradiation of AK1ex worms with 3600 rad (1 rad = 0.01 Gy) of x-rays (x-ray chamber: RUM 9421-070-77002, Philips, Netherlands; dosimeter: PTW-SN4, PTW, Germany). The progeny of these worms was then screened for 100% transmittance of the Roller phenotype to obtain the C. elegans line AK1int (AK1 integrated) with the chromosomally integrated transgenes.
