سابقه و هدف: بیماری آلزایمر شایع ترین عامل زوال عقل یا دمانس در کهن سالی می باشد. این بیماری یک اختلال از بین برنده نورون ها می باشد. از آن جایی که فاکتور رشد فیبروبلاست fibroblast growth factor 1 (fgf1) به صورت انتخابی نورون ها را از اثرات نوروتوکسیتی محافظت می کند، هدف ما از این مطالعه بررسی ارتباط بین پلی مورفیسم (g/a(rs34011 ژن fgf1 با بیماری آلزایمر در ساکنین جنوب غربی ایران می باشد. مواد ...
Extracellular fibroblast growth factor 1 (FGF1) acts through cell surface tyrosine kinase receptors, but FGF1 can also act directly in the cell nucleus, as a result of nuclear import of endogenously produced, non-secreted FGF1 or by transport of extracellular FGF1 via endosomes and cytosol into the nucleus. In the nucleus, FGF1 can be phosphorylated by protein kinase C δ (PKCδ), and this event ...
The fibroblast growth factor 1 (FGF1) gene is expressed primarily in the kidney and may contribute to hypertension. However, the biologic mechanisms underlying the association between FGF1 and BP regulation remain unknown. We report that the major allele of FGF1 single nucleotide polymorphism rs152524 was associated in a dose-dependent manner with systolic BP (P = 9.65 × 10(-5)) and diastolic B...
Cholinergic neurons in the dorsal motor nucleus of the vagus (DMNV) are particularly vulnerable to laryngeal nerve damage, possibly because they lack fibroblast growth factor-1 (FGF1). To test this hypothesis, we investigated the localization of FGF1 in cholinergic neurons innervating the rat larynx by immunohistochemistry using central-type antibodies to choline acetyltransferase (cChAT) and p...
BACKGROUND The clinical significance of fibroblast growth factor 1 (FGF1) has been revealed in several cancers, including ovarian cancer, breast cancer, and bladder cancer. However, the clinical significance of FGF1 in gastric adenocarcinoma has not been explored. PATIENTS AND METHODS In our experiments, we systematically evaluated FGF1 expression in 178 cases of gastric adenocarcinoma with i...
Increased insulin demand resulting from insulin resistance and/or overnutrition induces a compensatory increase in β-cell mass. The physiological factors responsible for the compensation have not been fully characterized. In zebrafish, overnutrition rapidly induces compensatory β-cell differentiation through triggering the release of a paracrine signal from persistently activated β-cells. We id...
Background and purpose Angiosarcoma is associated with a poor prognosis and is treated with radiotherapy. Although FGF1 is a potential radioprotector, the influence of FGF1 on the malignancy of angiosarcoma remains unknown. Materials and methods Highly stable FGF1 mutants, which exhibit stronger mitogenic activity than wild-type FGF1, were examined as strong radioprotectors and signaling agon...
The prototypical fibroblast growth factor receptor (FGFR) extracellular domain consists of three Ig domains (D1-D3) of which the two membrane-proximal D2 and D3 domains and the interconnecting D2-D3 linker bear the determinants of ligand binding and specificity. In contrast, D1 and the D1-D2 linker are thought to play autoinhibitory roles in FGFR regulation. Here, we report the crystal structur...
Fibroblast growth factor-1 (FGF1), a member of the FGF family of growth factors, is localized in cholinergic neurons where it has trophic activity. We recently reported that cholinergic neurons in the dorsal motor nucleus of the vagus (DMNV) contain little FGF1, raising the possibility that FGF1 is not localized to parasympathetic preganglionic cholinergic neurons. To clarify this issue, we inv...
FGF1 is highly expressed in neurons and it has been proposed to play a role in the neuroprotection and in regeneration. Low FGF1 expression in neurons has been linked to increased vulnerability in cholinergic neurons. Previous reports have shown that the expression of FGF1 in rat brain is localized to the cholinergic nuclei of the medulla oblongata, with low ratio of neurons positive for FGF1 i...
