Description

Functional Role of GADD45G

GADD45G (Growth Arrest and DNA Damage-Inducible Gamma) is a tumor suppressor involved in:

  • Cell Cycle Arrest: Mediates G2/M checkpoint activation via p53-dependent pathways, inhibiting cyclin B1/Cdc25C activity .

  • DNA Repair: Binds proliferating cell nuclear antigen (PCNA) to facilitate DNA damage response .

  • Immune Regulation: Enhances CD8+ T cell anti-tumor activity by promoting IFN-γ production and p38 MAPK signaling .

Cancer Biomarker Potential

  • Hepatocellular Carcinoma (HCC):

    • GADD45G is downregulated in HCC tissues, correlating with advanced tumor stage (T3/T4), high serum AFP levels, and poor prognosis .

    • Restoring GADD45G expression via 4-methoxydalbergione (4MOD) suppresses HCC growth in vivo, indicating therapeutic potential .

Breast Cancer

  • Overexpression of GADD45G inhibits tumor formation and metastasis by suppressing epithelial-mesenchymal transition (EMT) .

Mechanistic Insights

  • MAPK Pathway Activation: GADD45G upregulates T-bet and Eomes in CD8+ T cells, enhancing anti-tumor immunity .

  • Embryonic Stem Cell Differentiation: GADD45G initiates differentiation by activating MAPK signaling, reducing self-renewal capacity .

Technical Considerations

  • Antibody Validation:

    • Optimal dilution must be determined empirically for WB, IHC, or IF/ICC .

    • Homodimerization of GADD45G is critical for its interaction with PCNA and growth-inhibitory functions .

Clinical and Therapeutic Implications

  • Biomarker Utility: GADD45G expression levels serve as a prognostic marker in HCC and breast cancer .

  • Therapeutic Target: Small molecules like 4MOD that upregulate GADD45G could enhance anti-tumor responses in liver cancer .

Target Background

Function
GADD45G is involved in the regulation of cell growth and apoptosis. It mediates the activation of the stress-responsive MTK1/MEKK4 MAPKKK signaling pathway.
Gene References Into Functions
  1. A study on an Eastern Chinese population found that individuals carrying the GADD45G rs8252T variant genotype had a significantly lower risk of developing non-small-cell lung cancer (NSCLC). Individuals with the CT/TT genotypes of the rs8252 variant displayed significantly higher levels of GADD45G mRNA expression compared to those with the CC genotype in the target tissues. There was some evidence of interactions between the rs8252 genotypes and sex regarding NSCLC risk. PMID: 27861856
  2. In contrast to solid tumors, the frequency of GADD45gamma methylation is higher in diffuse large B-cell lymphoma (DLBCL) and may be associated with disease progression. Nodal involvement is more likely to be present in patients with unmethylated GADD45gamma. PMID: 25912017
