Abstract

Fibroblast growth factors (FGFs) are small polypeptide growth factors, all of whom share in common certain structural characteristics, and most of whom bind heparin avidly. Many FGFs contain signal peptides for secretion and are secreted into the extracellular environment, where they can bind to the heparan-like glycosaminoglycans (HLGAGs) of the extracellular matrix (ECM). From this reservoir, FGFs may act directly on target cells, or they can be released through digestion of the ECM or the activity of a carrier protein, a secreted FGF binding protein. FGFs bind specific receptor tyrosine kinases in the context of HLGAGs and this binding induces receptor dimerization and activation, ultimately resulting in the activation of various signal transduction cascades. Some FGFs are potent angiogenic factors and most play important roles in embryonic development and wound healing. FGF signaling also appears to play a role in tumor growth and angiogenesis, and autocrine FGF signaling may be particularly important in the progression of steroid hormone-dependent cancers to a hormone-independent state.

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

  • GHK-Cu increases the expression of bFGF and VEGF in irradiated human dermal fibroblasts at a concentration of 1 nM.

    “GHK-Cu at a concentration of 1nM increases the expression of basic fibroblast growth factor (bFGF) and vascular endothelial growth factor (VEGF) in irradiated human dermal fibroblasts, both of which aid blood vessel formation and blood flow into damaged tissues [4–6].”

    From The potential of GHK as an anti-aging peptide (2020) · cites this paper as [5]

    The sections on FGF signaling and repair discuss angiogenesis and wound healing, but do not address GHK-Cu treatment. Searches for GHK-Cu, irradiated dermal fibroblasts, and the 1 nM concentration found no passage reporting the claimed increase in bFGF or VEGF expression. (LLM, conf=0.76)

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.
