Disease relevance of LGALS7

  • Here, we provide evidence indicating that galectin-7 functions as an important molecule in the dissemination of lymphoma cells in vivo [1].
  • For example, up-regulation of galectin-7 is associated with rat mammary carcinomas and with progression to T-cell malignancy [1].
  • We also found that inhibition of galectin-7 in aggressive lymphoma cells correlated with a decreased invasion of tumor cells in target organs and a reduced expression of matrix metalloproteinase-9, a gene associated with a poor prognosis in non-Hodgkin's lymphoma [1].
  • Galectin-7 is a beta-galactoside binding protein specifically expressed in stratified epithelia and notably in epidermis, but barely detectable in epidermal tumors and absent from squamous carcinoma cell lines [2].
  • In serum-supplemented proliferation assays, galectin-7 reduced neuroblastoma cell growth without the appearance of features characteristic for classical apoptosis [3].

Physical interactions of LGALS7

  • The p53-induced apoptosis was abrogated by NS5A and the inhibition effect correlates well with the binding ability of NS5A to p53 [22].
  • The ability of ATF3 to stabilize p53-induced pathways thus represents a means of effectively countering DNA damage caused by environmental insult the latter leading to oncogene activation and ultimately malignant transformation [23].
