Abstract

The paired box 7 (Pax7) gene encoding for the transcription factor can regulate the conversion of stem cells into myogenic cells and participate in the development and regeneration of skeletal muscle. The aims of this study were to detect variations of the Pax7 gene by DNA pool sequencing and aCRS–RFLP methods in 1441 cattle from five breeds and to investigate their associations with growth traits in Nanyang and Chinese red steppe cattle. Altogether, three novel single nucleotide polymorphisms (SNPs) were identified in the last intron of the Pax7 gene: NC_007300: ss1 (g. G103688A), ss2 (g. T103735C), and ss3 (g. A103764T). Genotypes and the referring haplotype frequencies showed a high similarity trend among five breeds, and the G, T, and A allele frequencies of the three loci were always superior when separate or in combination. Association analysis of the single SNPs and haplotype combinations revealed that the T allele of ss2 and ss3 loci and the haplotype H 2 H 2(GG-TT-TT) showed significant effects on growth traits such as body height, body mass, and chest girth in cattle at early stages (6 and 12 months old) (P < 0.05). The results showed that Pax7 gene variations and their corresponding genotypes may be considered as molecular markers for economic traits in cattle breeding.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Human pluripotent stem cells induced to express PAX7 and treated with defined chemical cocktails yield transplantable muscle progenitors that refill the satellite cell niche and maintain dystrophin-positive fibers in dystrophin-deficient mice.

    “Induced expression of PAX7 and exposure to defined chemical cocktails145–147 in human pluripotent stem cells has been shown to generate engraftable muscle progenitor cells that replenish the satellite cell compartment and sustain formation of dystrophin-positive myofibers in dystrophin-deficient mice145,147.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
