Our project
Our abstract
A first idea: cancer treatment with genetically modified blood cells
As cancer cells need a lot of energy to replicate themselves, they should be well provided with blood. Therefore, blood cells could be the right choice for in situ treatment of cancer. First, we should immobilize these blood cells on the cancer cells. Subsequently, these blood cells should secrete specific agents that reduce the activity of the cancer cells. (These 2 steps may come in handy if we want to split up in 2 subgroups)
Notes
- Sounds like a great idea! [http://en.wikipedia.org/wiki/Avastin Anti-angiogenic therapy] is one of the big hopes for anti-tumor treatments. But let's keep in mind that angiogenesis (the formation of blood vessels) is only a late hallmark of tumors [http://www.google.be/url?sa=t&ct=res&cd=1&url=http%3A%2F%2Fwww.weizmann.ac.il%2Fhome%2Ffedomany%2FBioinfo05%2Flecture6_Hanahan.pdf&ei=-7E2SLbLGJCE1wblseHQDQ&usg=AFQjCNHirXaVMmdQNGl-72bk5jRva4106Q&sig2=L18rRG56VaP9wIB_mAENpA (more about these hallmarks of cancer -PDF)]. It is however a significant barrier to break through if the tumor has to grow past a certain (very limited) size. So this would be more like a therapy for later-stage malignancies, which would also be great because it's often the metastasis (the spreading of) of the tumor that is causing the more visible effects of the cancer. (pain, deterioration, ... and eventually, if untreated death). - Jonas 12:09, 23 May 2008 (UTC)
- Anyhow, if we proceed with this idea, it will be a challenge to get everything ready and produced in the erythrocyte (red blood cell) before it loses it's nucleus and thus also the ability to initiate de novo transcription. And to keep all this machinery silent in non-docked erythrocytes. I'm liking this challenge though :) - Jonas 12:09, 23 May 2008 (UTC)
- I just thought of something that might be quite critical. If I recall correctly, there are 3 main ways in which tumors acquire blood supply.
- The first one is through a recapitulation of embryonic development. This is the recruitment of vascular endothelial precursors or the activation of local endothelium via factors like VEGF (angiogenic sprouting or intussusceptive growth). In this case, the 'vessels' of the tumor blood supply are lined mostly with endothelial cells which are actually NOT malignant, but are kind of working together with the tumor cells.
- A successful cancer metastasis (a secondary tumor, derived from the original) will co-opt blood vessels and these will thus also be lined mostly with endothelium cells.
- The third way to achieve blood supply is through vasculogenic mimicry, where the tumor cells actually DO line the bloodstream and mimic the normal vascular endothelium. Here tumor biomarkers should be directly displayed to the passing erythrocytes and would thus be potential targets for use in this approach.
- OK, now for my point. In all these cases the vessels are highly abnormal, both structurally and functionally. They've got many holes, inhomogeneous bloodflow, are leaky, ... so it's very likely there will be exposed markers we can focus on but this will probably not always be the case. - Jonas 14:17, 23 May 2008 (UTC)
