Description

Primary Applications of FGF18 Antibodies

FGF18 antibodies are utilized in diverse experimental workflows:

ApplicationProtocol DetailsKey Uses
Western Blot (WB)Detects FGF18 at ~24 kDa; requires SDS-PAGE and antigen retrieval Quantifying FGF18 expression in liver, heart, and cancer tissues
ImmunohistochemistryOptimal dilution: 1:50–1:500; TE buffer (pH 9.0) recommended for antigen retrieval Localizing FGF18 in kidney, embryo, and heart tissues
ImmunofluorescenceDilution range: 1:200–1:800; validated in HepG2 cells Visualizing FGF18 in cellular compartments (e.g., extracellular matrix)
ELISAConjugated forms (HRP, FITC) enable quantitative assays Measuring FGF18 levels in serum or culture supernatants

Liver Fibrosis Mechanisms

  • FGF18 promotes hepatic stellate cell (HSC) proliferation via Ccnd1 induction, exacerbating fibrosis .

  • Overexpression in hepatocytes correlates with elevated COL1A1 and ACTA2 in human liver biopsies .

Cartilage Repair and Osteoarthritis

  • FGF18 activates FGFR3c to stimulate chondrogenesis, reducing osteoarthritis progression in clinical trials (e.g., sprifermin) .

  • Intravertebral disc degeneration is inhibited in rabbit models via FGF18-mediated cartilage protection .

Oncology Insights

  • FGF18 exhibits dual roles: elevated in some cancers but not directly oncogenic .

  • HDAC7-driven β-catenin-FGF18 pathways promote NSCLC metastasis, identified using FGF18 antibodies .

Target Background

Function
FGF18 plays a crucial role in regulating cell proliferation, differentiation, and migration. It is essential for normal ossification and bone development. Additionally, FGF18 stimulates hepatic and intestinal proliferation.

  • FGF18 has been implicated in the growth and metastasis of breast cancer. PMID: 29901199
  • A study in a Chinese population did not find a significant association between rs9313548 and developmental dyslexia, aligning with previous research. PMID: 29240020
  • Research has demonstrated that miR-139 suppresses FGF18, consequently inhibiting proliferation, apoptosis, invasion, migration, and tumor-induced angiogenesis in hepatocellular carcinoma (HCC) cells. FGF18 is considered a potential prognostic biomarker and therapeutic target in HCC patients, and miR-139 could be a promising treatment strategy through FGF18 suppression. PMID: 28765917

  • Tumors from ovarian cancer patients exhibit increased FGF18 expression levels, correlated with microvessel density and M2 macrophage infiltration. PMID: 24018557
  • FGF8, FGF17, and FGF18 are involved in autocrine and paracrine signaling in HCC, enhancing the survival of tumor cells under stress conditions, malignant behavior, and neoangiogenesis. PMID: 21319186
