Text-mined interactions from Literome
Noguchi et al., Br J Haematol 2001
(Lymphoma, T-Cell) :
Epstein-Barr virus ( EBV ) -encoded
latent membrane protein 1 (LMP-1) is essential for immortalization of B cells by EBV, protects the infected cells from apoptotic cell death and
induces Bcl-2 expression ... Suppression of
LMP-1 expression by antisense oligodeoxynucleotides ( AS-oligo ) to LMP-1 inhibits proliferation, promotes apoptosis and
suppresses Bcl-2 expression in EBV transformed B cells ... These results suggest that proliferation, inhibition of apoptosis and
Bcl-2 expression in EBV positive NK cell lymphoma cells are not directly
regulated by
LMP-1 as in EBV transformed B-cell lines, but are probably mediated through other signal transducing systems
Lee et al., Cancer Lett 2009
(Nasopharyngeal Neoplasms) :
We found that LMP-1 diminished the pro-apoptotic activity of Par-4 and negatively regulated Par-4 protein by de novo synthesis ; moreover, although LMP-1 accelerated a Par-4 activator, PKA, we demonstrated that
LMP-1 also activated the PI3K/Akt pathway and
increased Bcl-2 expression to suppress the activity of Par-4
Li et al., Zhonghua Shi Yan He Lin Chuang Bing Du Xue Za Zhi 2011
(Epstein-Barr Virus Infections...) :
The increased expression of
Bcl-2 may not be
induced by
LMP1
Rowe et al., J Virol 1994
:
However, it was not possible to ascertain whether
Bcl-2 upregulation was a specific consequence of
LMP1 expression or an artifact of the selection procedure whereby rare Bcl-2+ cells already present in the starting population might best be able to tolerate the potentially toxic effects of LMP1
Murray et al., Blood 1996
(Herpesviridae Infections...) :
One EBV protein, BHRF1, is a homologue of BCL-2, whereas another, the
latency membrane protein 1 (LMP-1) ,
upregulates BCL-2 expression in vitro
Wang et al., Cancer Res 1996
:
However, the maximum
induction of
Bcl-2 by
LMP1 takes about 48-72 h
Inoue et al., Nihon rinsho. Japanese journal of clinical medicine 1997
:
However,
regulation of the
Bcl-xL , Cdk4 and 6 and p27kip-1 expression by
LMP1 and the molecular mechanism of LMP1 mediated B cell transformation remain to be elucidated
Piché et al., Gene Ther 1998
(Lymphoproliferative Disorders) :
LMP1 mediated up-regulation of
Bcl-2 is thought to be an important element in this process
