malfunction | deletion of Lfng in mice causes altered Notch activation in the prostate, associated with elevated accumulation of Notch1, Notch2, and Notch4 intracellular domains, decreased levels of the putative Notch3 intracellular fragment, as well as increased expression of Hes1, Hes5, and Hey2. Loss of Lfng results in expansion of the basal layer, increased proliferation of both luminal and basal cells, and ultimately, prostatic intraepithelial neoplasia. The Lfng-null prostate shows down-regulation of prostatic tumor suppressor gene NKX3.1 and increased androgen receptor expression. Deletion of Lfng caused dysregulation of Notch signaling in the prostate. Increased epithelial proliferation and prostatic intraepithelial neoplasia in the Lfng-null mutant gland | Mus musculus |
malfunction | knockdown of LFNG in DU-145 prostate cancer cells leads to expansion of CD44+CD24- and CD49f+CD24- stem/progenitor-like cell population associated with enhanced prostatosphere-forming capacity. The Lfng-null prostate shows down-regulation of prostatic tumor suppressor gene NKX3.1 and increased androgen receptor expression | Homo sapiens |
additional information | expression of LFNG and NKX3.1 are positively correlated in publically available human prostate cancer data sets | Homo sapiens |
physiological function | fringe genes code for O-fucosylpeptide 3-beta-N-acetylglucosaminyltransferases that can add N-acetylglucosamine to O-linked fucose residues on epidermal growth factor repeats of Notch. This modification modulates specificity and sensitivity of Notch receptors for different ligands. Therefore, fringes are powerful regulators of ligand-mediated Notch signaling. Tumor-suppressive activity of lunatic fringe in prostate through differential modulation of Notch receptor activation. The enzyme plays a critical role in regulation of prostate epithelial differentiation and proliferation, as well as in prostate tumor suppression | Mus musculus |
