Perry,

Here is the new shark cartilage protein fraction used for angiogenesis. The fraction is composed of two proteins with low molecular weights and is effective topically and orally. It goes under several different names.

AE 941.


AE 941 [Arthrovas, Neoretna, Psovascar] is shark cartilage extract that inhibits angiogenesis. AE 941 acts by blocking the two main pathways that contribute to the process of angiogenesis, matrix metalloproteases and the vascular endothelial growth factor signalling pathway. When initial development of AE 941 was being conducted, AEterna assigned the various indications different trademarks. Neovastat was used for oncology, Psovascar was used for dermatology, Neoretna was used for ophthalmology and Arthrovas was used for rheumatology. However, it is unclear if these trademarks will be used in the future and AEterna appears to only be using the Neovastat trademark in its current publications regardless of the indication.

Low molecular weight fraction of shark cartilage can modulate immune responses and abolish angiogenesis.

Shark cartilage has proven to have inhibitory effects on angiogenesis. In this research, we studied the effects of shark cartilage on the immune system. Firstly, we isolated and purified a shark cartilage protein fraction with the most immunostimulatory effects. Our fraction was composed of two proteins with molecular weights of about 14 and 15 kDa. This fraction highly augments delayed-type hypersensitivity response against sRBC in mice, and decreases the cytotoxic activity of Natural Killer cells. Furthermore, intraperitoneal injection of this fraction to tumor-bearing mice could increase T-cell infiltration into the tumor, and decrease the tumor lesion size. Also, this fraction has strong inhibitory effect on HBMEC proliferation and migration in fibrin matrix. According to these results, we suppose that this fraction is a good candidate for further studies in cancer therapy.

Thanks Dr. Nase.
If and when this extract is formulated into a topical, I would be one of the first in line. I would guess, though, that since there are so many other, presumably more easily attained AI's, that shark cartilidge won't be a major player? (I'm not too crazy about just another reason to slaughter sharks, anyway).
Heck, probably would be easiest to get thalidomide from Mexico....
I am still wondering whats the deal with minocycline?
Regards,
Perry

I think the topical is out?

Are you talking about minocyline and angiogenesis?

Hi Dr. Nase,
(I can post now...I can post now!)
Anyway...Yes...I've read many times that minocycline is a potent AI (and as I'm sure you're aware, the NCI lists minocycline as such).
Hmmmm.....
Thanks,
Perry
I think many would just like to, in any possible way, do anything to retard the progression of rosacea until better txs are here (this is why I am interested in green tea, soy, etc, supplementation). This is really all we can do for now, while we're waiting for something better, no?
ps2 I've been reading a lot about green tea lately...read of an interesting study (didn't actually see the abstract or the study) about (green tea catechins) inhibiting neovascularization in mice retinas....
