Abstract

The bacteriocidal capacity of phagocytic cells is impaired in X-linked chronic granulomatous disease (X-CGD), a disorder characterized by the absence of functional plasma-membrane-associated NADPH oxidase. The components of this oxidase system, their correspondence with specific genetic loci, and the primary protein defect in X-CGD remain incompletely defined. We recently reported cloning of the putative X-CGD gene on the basis of DNA linkage. To identify the predicted protein in vivo, antibodies were raised to a synthetic peptide derived from the complementary DNA sequence and to a fusion protein produced in Escherichia coli. In Western blots antisera detect a neutrophil protein of relative molecular mass in 90,000 (90K) that is absent in X-CGD patients. Antisera also react with the larger component of cytochrome b recently purified from neutrophil plasma membranes as a complex of glycosylated 90K and non-glycosylated 22K polypeptides. Based on our identification of the X-CGD protein in vivo, we propose that one of its critical roles is to interact with the 22K species to form a functional cytochrome b complex.

  • H2O2 can modulate gene expression by epigenetic modification and activate transcription factors such as AP-1, NRF2, CREB, HSF1, HIF-1, TP53, NF-κβ, NOTCH, SP1, SCREB-1 and FOXO family.

    “For example, H2O2 can also modulate genes expression by epigenetic modification and activate transcription factors such as AP-1, NRF2, CREB, HSF1, HIF-1, TP53, NF-κβ, NOTCH, SP1, SCREB-1 and FOXO family [14,15,16,17,18,19,20,21,22].”

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.
