Disease relevance of UBE1L

 

High impact information on UBE1L

 

Biological context of UBE1L

  • The UBE1L gene isolated from the chromosome 3p21 region has an extremely reduced level of mRNA in lung cancer [3].
  • The human UBE1L gene, for which the product may well play a role in the ubiquitin system because of its high degree of identity to the ubiquitin activating enzyme, is located at 3p21, a chromosomal region consistently showing loss of heterozygosity in lung cancer [4].
 

Anatomical context of UBE1L

  • In contrast, UBE1L mRNA expression was markedly repressed in several cancer cell lines [5].
  • Studies done on paraffin-embedded and fixed tissues revealed abundant UBE1L, but low levels of cyclin D1 expression in the normal human bronchial epithelium, indicating an inverse relationship existed between these species [1].
  • 5'-Azacytidine-induced demethylation did not result in a marked increase of the UBE1L mRNA level in the tumor cell lines [4].
  • On D8 and D10 TCDD reduced myocyte proliferation [6].
  • To evaluate effects of TCDD on differentiation of coronary arteries, chick embryo hearts from incubation days 8 (D8), D10, and D12 were stained with anti-alpha-smooth muscle actin [6].
 

Associations of UBE1L with chemical compounds

 

Regulatory relationships of UBE1L

  • In a dose-dependent manner, wild-type but not mutant UBE1L species repressed cyclin D1 expression [1].
 

Other interactions of UBE1L

  • UBE1L is proposed as a direct pharmacological target that overcomes oncogenic effects of PML/RARalpha by triggering its degradation and signaling apoptosis in APL cells [2].
  • A physical association was found between UBE1L and ISG15 in vivo [5].
  • 3. FISH analysis showed that the distance between UBE1L and RBM5 in 3p21.3 is about 265 kb [7].
  • A homologue of UBE1, UBE1L, is located at 3p21 [7].
  • These findings also provide a mechanistic basis for the tumor suppressive effects of UBE1L through cyclin D1 repression [1].
 

Analytical, diagnostic and therapeutic context of UBE1L

  • Microarray analysis revealed involvement of an E1-like ubiquitin-activating enzyme, UBE1L, in this induction [8].
  • Although proteins that bind to the D8 element appear ubiquitous, this element does yield tissue-specific complexes in mobility shift assays [9].
  • In addition, temporal and spatial patterns of apoptosis were detected by TUNEL on D3, D5, D6, D8, and D10, and immunohistochemistry was used to identify the origin of apoptotic cells on D6 [6].
