TNF — TNFAIP6
Text-mined interactions from Literome
Guo et al., Zhonghua Er Ke Za Zhi 2004
:
To explore the relationship between the differential expression of TSG-6 and adipocyte differentiation, adipogenesis and obesity, the present study aimed to investigate the changes of TSG-6 gene expression during 3T3-L1 preadipocyte differentiation and to analyze the regulative
role of
TNF-alpha on
TSG-6 gene expression in matured 3T3-L1 adipocytes ... The inhibition
effect of
TNF-alpha on
TSG-6 gene mRNA expression generally tended to be reinforced with the increasing concentrations of TNF-alpha and the elongation of time course, except for the period of 6 - 24 h after the stimulation of 10.0 ng/ml TNF-alpha ... The inhibitory
effect of
TNF-alpha on
TSG-6 gene expression is generally dose correlated

:
A functional study of TNF demonstrated that depletion of endogenous TNF decreased oocyte competence and TNFAIP6 expression in cumulus cells, while
TNF in IVM medium
regulated TNFAIP6 expression in cumulus cells
Klampfer et al., J Biol Chem 1995
:
We have previously shown that transcription factors of the NF-IL6 and AP-1 families cooperatively modulate
activation of the
TSG-6 gene by
TNF or interleukin 1 (IL-1) through a promoter region that contains an NF-IL6 site ( -106 to -114 ) and an AP-1 element ( -126 to -119 )
Klampfer et al., Mol Cell Biol 1994
:
Tumor necrosis factor alpha (TNF-alpha) and interleukin-1 (IL-1)
activate transcription of the
TSG-6 gene in normal human fibroblasts through a promoter region ( -165 to -58 ) that encompasses an AP-1 and a NF-IL6 site ... Consistent with this possibility, IL-1 and
TNF-alpha markedly increase the binding of Fos and Jun to the AP-1 site, and NF-IL6
activates the native
TSG-6 promoter ... The finding that the inhibitor isoform antagonizes
activation of the native
TSG-6 promoter by IL-1 and
TNF-alpha suggests that NF-IL6 has a physiologic role in these cytokine responses
