Abstract

The mRNAs encoding the catalytic subunits of the type 1 phosphatase and the alpha and beta forms of phosphatase 2A (termed 2A alpha and 2A beta) were detected in all the porcine tissues examined (brain, heart, muscle, liver, kidney and ovaries). Total phosphatase 2A transcripts were about 10 times more abundant in brain and heart than in the other tissues while the distribution of phosphatase 1 mRNA showed significantly less variation. Phosphatase 2A alpha mRNA was about 10 times more abundant than phosphatase 2A beta mRNA in most tissues. Similarly, both the alpha and beta forms of the mRNA of the catalytic subunit of the phosphatase 2A were present in all the rat tissues examined. In addition to the 2 kb mRNA generally expressed, rat tissues also express a 2.8 kb mRNA related to 2A alpha and a 1.3 kb mRNA related to 2A beta.

Claims the paper makes

We couldn’t retrieve this paper’s full text, 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?

  • Cα (Ppp2ca) is expressed about 10-fold higher than Cβ (Ppp2cb) in most tissues, mainly due to the more active promoter region of Ppp2ca.

    “In general, Cα (Ppp2ca) is expressed to a 10-fold higher extent than Cβ (Ppp2cb), mainly due to the more active promotor region of Ppp2ca in most tissues [33] (Fig. 2).”

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.
