Common Questions and Answers about Temozolomide apoptosis

Avatar n tn I am a 25 year old female. I was diagnosed with a primary brain tumor in June 2008 and underwent surgery to remove it. It was the size of an apple and diagnosed a grade 2 tumor. It grew back in September 2008 and that's when i began rigorous radiation and oral chemotherapy (Temozolomide). My recent MRI has showed the regrowth of the tumor to be "gone." The plan is to take the Temozolomide for 2 years along with Accutane (which helps the oral chemotherapy work better).
Avatar m tn Not much is known about Brininapant, and because it targets the host rather than the virus, side effects are always a concern. I believe it blocks IAP (Inhibition against Apoptosis Protein) which is over-expressed in virally infected cells. I also believe apoptosis is driven by TNF? Because WEH has such a good reputation, it certainly raises a lot of hope.
Avatar m tn Being the analogue of key cell metabolites the active principles of the composite therapeutics, Molixan®, have high bioavailability, therefore, being introduced into biological media they instantly translocate into target cells inducing cascade mechanism of biochemical reactions regulating cell metabolism, proliferation, differentiation and apoptosis forming a wide range of immunomodulating and hepatoprotective effects.
Avatar m tn The hormone also decreases cellular abundance and activation of proteolytic caspases and of BAX and causes increased expression of X-linked inhibitor of apoptosis (XIAP). The anti-apoptotic effects of thyroid hormone largely are initiated at a cell surface thyroid hormone receptor on the extracellular domain of integrin αvβ3 that is amply expressed and activated in cancer cells." ...
Avatar m tn s palsy can be overcome, there are other dangers in the long term use of an apoptosis enhancer, that need to be carefully assessed in trials increasing dose and duration to the level needed for hbv therapy.
Avatar f tn As far as I know there is no medication available to stimulate nerve repair or any sort. There has been some research in certain drugs for slowing nerve damage due to apoptosis or "programmed cell death." I must state that none have been proved effective in humans, though and none are approved for use at present. Usually ischemic optic neuropathy is not a slow process but is rather abrupt usually. You may actually have other problems in addition to optic neuropathy.
Avatar m tn It is my understanding that infected liver cells die by either natural or induced cell death by apoptosis or lysis by immune cells. Apoptosis is supposed to be an orderly process with the whole dead cell eaten cleanly by macrophages. Some literature suggested when infected liver cells divide (by mitosis), some cccDNA may be lost , into the cytoplasm or outside the cells?
Avatar m tn For those with the background to understand this it has to do with mitochondrial dysfunction, apoptosis (programmed cell death), and the inhibition of apoptosis by some antihistamines at low doses.
Avatar m tn One has to very seriously consider the possibility that the ongoing accumulation of non secreted surface antigen in both infected and integrated cells will couse severe cellular stress, sensitizing these cells to apoptosis and also eliciting some of the innate cellular antiviral defenses available to hepatocytes themselves.
Avatar m tn even though the HPV virus may clear within time (God willing), its always good to know that people are looking for a cure to any thing viral. http://www.ll.mit.edu/news/DRACO.html "DRACO selectively induces apoptosis, or cell suicide, in cells containing any viral dsRNA, rapidly killing infected cells without harming uninfected cells. As a result, DRACO should be effective against virtually all viruses, rapidly terminating a viral infection while minimizing the impact on the patient.
Avatar m tn it speculates on the concept that infected cells are preparing for self destruction by apopotosis, similar to cancer cells. Certain proteins are inhibitory to this process, they can be blocked by birinapant to act, so apoptosis can proceed and infected cells or cancer cells are selectively removed. hbv is not causing much, if any, cytopathic effects in infected hepatocytes. Consider the long immuntolerant phase, where the intensely infected liver seems perfectly healthy in a functional sense.
Avatar m tn “Our findings suggest that saffron provides an anti-cancer protective effect by promoting cell death (apoptosis), inhibiting proliferation of cancerous cells, and blocking inflammation,” researchers noted.
Avatar f tn Yeah,It would make sense that hepatocytes that have had viral gene fragments inserted into cancer prone locations in their genome would subsequently undergo apoptosis to eliminate the cancer-threat. I would also think such cancer-protective mechanisms are better enforced in younger people than older people. That would explain why most HCC risk models associate no increased HCC risk to guys below 40.
Avatar m tn Rationale for treatment with birinapant Like cancer cells, cells that are infected with certain viruses may escape apoptosis. We have conducted pre‑clinical studies to evaluate the potential development of birinapant as an infectious disease therapeutic to overcome this “escape‑from‑apoptosis” in infected cells. We believe this is a novel approach.
Avatar n tn Cell death or Apoptosis as is known is a programmed one,and I presume body would seek a balance by destroying a few.
Avatar f tn In some of the time periods analyzed, alterations were observed in the expression of genes related to apoptosis (B-cell leukemia/lymphoma 2, inhibitor of apoptosis 2) and to fibrosis (procollagen I, matrix metalloproteinase 7). In the recovery period (Groups C and D), folic acid administration was associated with increased hepatic inflammation and apoptosis and with a decrease in the tissue inhibitor of metalloproteinase-3 expression following 1 week of recovery.
