Abstract

Evidence is reviewed supporting the view that vitamin A (retinol) and its metabolite, retinoic acid, called natural retinoids, are major factors involved in differentiation and in maturation of the lungs. This conclusion is based on morphological observation that lack of this dietary micronutrient causes keratinizing squamous metaplasia of the bronchopulmonary tree that can be reversed by refeeding the animal with retinol. In addition to these observations suggesting an indirect participation of retinol and/or retinoic acid in the differentiation of this organ, more direct evidence is presented that this vitamin is involved in pulmonary gene expression. Adult as well as fetal lungs accumulate retinyl esters, the storage form of vitamin A, contain specific retinol- and retinoic acid-binding proteins and, more importantly, express several isoforms of nuclear retinoic acid receptors. These proteins are involved in activation and repression of specific genes regulated by retinoic acid. That retinol and/or retinoic acid may be involved in lung maturation is suggested by experimental results showing depletion of lung retinyl esters at birth, by significant alterations in the levels of the cellular retinoic acid-binding protein during lung maturation and, more importantly, by reduction in the morbidity of prematurely born human neonates who are given vitamin A because they are susceptible to bronchopulmonary dysplasia.

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?

  • Vitamin A is an essential micronutrient that the human body cannot synthesize on its own and must ingest.

    “Vitamin A is an essential micronutrient, which means that the human body cannot synthesize it on its own and must be ingested.”

    From The Role of Vitamin A in Retinal Diseases (2022) · cites this paper as [6]

  • Vitamin A is stored in the body in the form of retinyl ester; the highest amounts are stored in the liver, but it is also found in adipose tissue, lungs and the RPE.

    “The highest amounts of vitamin A are stored in the liver, but it is also found in adipose tissue, lungs and the RPE [2,3,4,5,6].”

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.
