Our results demonstrate: 1) adenovirus infection of MCL cells despite the absence of receptor/coreceptor molecules known to be important for adenovirus infection of other cells types; 2) cytotoxicity of MCL cells after infection with specific adenovirus mutants; 3) a high degree of cytotoxicity after infection of some patient samples with viruses lacking the E1B 19k "antiapoptotic" gene; and 4) cytotoxicity after infection with viruses containing mutations in E1A pRb or p300 binding.

|
To do so, virus products must interfere not only with the basal cell cycle regulators, such as pRb or Mad2, but also with the main surveillance pathways such as those controlled by p53 and ATM.
|
12 |

|
We found that, despite wt p53 and notwithstanding the activation of the checkpoint regulators p53, ATM and Mad2, ONYX-015 actively replicated in HUVEC cells.

|
Our data suggest that viral E1A and E4 region products can override all host cell-checkpoint response even at the presence of a full activation of the ATM/p53 pathway.
|
14 |

|
Furthermore, the E4 region alone seems to act independently of the E1B55K virus product in impairing the ATM-dependent, p53-independent G(2)/M checkpoint since dlE4 Ad5-infected cells arrested in G(2) while ONYX-015-infected cells did enter mitosis.

BALB/c mice were subcutaneously injected twice at a 3-week interval with 10 microg of ovalbumin or 10 microg of OVA plus 50 microg of ginsenosides Rg3, Rd, Rc, Rb1, Rb2, Rg1, Re or Rg2 or Quil A (n=5).

Blood samples were collected for measuring specific total-IgG, IgG1 and IgG2a, and splenocytes were harvested for determining lymphocyte proliferation as well as IFN-gamma and IL-5 production 2 weeks after the boosting.
|
18 |
17069940
|
Significantly enhanced splenocyte proliferative responses to Con A, LPS and OVA as well as the production of both IL-5 and IFN-gamma stimulated by OVA were also detected in mice immunized with OVA co-administered with Rg1 but not with Rb1, Re and Rg3.

Predictive value of p53 and pRb expression in superficial bladder cancer patients treated with BCG and interferon-alpha.
|

|
In these differentiating cells the degradation of p53 by the E6 protein and the abrogation of the pRb functions by the E7 protein lead to the reactivation of the DNA synthesis machinery.
|
25 |
17594948
|
These proteins are capable of inactivating p53 and pRb, which induces a continuous cell proliferation with the increasing risk of accumulation of DNA damage that eventually leads to cancer.

|
The transforming potential of HR-HPVs is based on the interaction of viral oncogene products E6 and E7 with the cellular tumor suppressor proteins p53 and pRB.
|
28 |
19177752
|
The E6 and E7 genes of HPVs are thought to play causative roles, since E6 promotes the degradation of p53 through its interaction with E6AP, an E3 ubiquitin ligase, whereas E7 binds to the retinoblastoma protein pRb and disrupts its complex formation with E2F transcription factors.
