Understanding angiogenesis process is crucial for modern medicine

Understanding angiogenesis process is crucial for modern medicine

Publish date: 2014-12-22

Angiogenesis, comprising a growth of blood vessels, is indispensable for proper organ functioning and repair. Abnormalities occurring in this crucial process are involved in various disorders such as cancer. Understanding its molecular background is the basis for the development of novel efficient drugs.

Angiogenesis is engaged in various physiological processes in which formation of new blood vessels is necessary just to mention wound healing or placenta formation during pregnancy. However, when the process is not regulated properly, it can contribute to serious medical consequences like cancer metastasis. The development of novel agents capable of switching “on” or “off” the formation of blood vessels is a great hope for treatment of various diseases.

Investigation of angiogenesis process began many years ago. The first important hypothesis was announced in 1971 by Dr. Judah Folkman, who is considered to be “the father of angiogenesis”. He stated that angiogenesis was an important factor involved in malignant tumor growth. After initial strong opposition of the scientific community, eventually the hypothesis was considered to be true. Since this time, a significant  progress in the field of “angiogenesis-regulating drugs” has been made.

Apart from cancer, inappropriate growth of blood vessels, either excessive or insufficient, is responsible for numerous disorders such as skin diseases, age-related blindness or cardiovascular disease. By focusing on the molecular events underlying the process of angiogenesis, it is possible to recognize proteins that act as stimulators or inhibitors of blood vessel formation. Professor Yihai Cao from the University of Leicester, who is a specialist in the area of vascular biology, presents the areas where drugs restoring proper angiogenic processes are already used.

Knowledge about angiogenesis is also necessary for elaboration of novel ways of treating obesity and associated metabolic disorders as the current approaches are highly insufficient. Recent findings strongly suggest that molecular factors modulating angiogenesis process influence the outgrowth and metabolism of adipose tissue. Professor Yihai Cao explains the mechanism of fatty cell expansion and a research that he performed on obese mice with the application of angiogenic inhibitor.

As it can be seen, unravelling the molecular events underlying pathological blood vessel growth is essential for modern medicine to provide real therapeutic options in a wide variety of diseases such as cancer or metabolic disorders associated with obesity.

My name is Jessica Luis, and I base in USA...My life is back!!! After 1 years of Broken marriage, my husband left me with two kids . I felt like my life was about to end i almost committed suicide, i was emotionally down for a very long time. Thanks to a spell caster called Dr Mohammed, which i met online. On one faithful day, as I was browsing through the internet,I came across allot of testimonies about this particular spell caster. Some people testified that he brought their Ex lover back, some testified that he restores womb,cure cancer,and other sickness, some testified that he can cast a spell to stop divorce and so on. i also come across one particular testimony,it was about a woman called Sonia,she testified about how he brought back her Ex lover in less than 2 days, and at the end of her testimony she dropped Dr Mohammed's e-mail address. After reading all these,I decided to give it a try. I contacted him via email and explained my problem to him. In just 48hours, my husband came back to me. We solved our issues, and we are even happier than before Dr Mohammed, is really a gifted man and i will not stop publishing him because he is a wonderful man...

'After being in relationship with Wilson for seven years,he broke up with me, I did everything possible to bring him back but all was in vain, I wanted him back so much because of the love I have for him, I begged him with everything, I made promises but he refused. I explained my problem to someone online and she suggested that I should contact a spell caster that could help me cast a spell to bring him back but I am the type that don't believed in spell, I had no choice than to try it, I meant a spell caster called Dr Zuma zuk and I email him, and he told me there was no problem that everything will be okay before three days, that my ex will return to me before three days, he cast the spell and surprisingly in the second day, it was around 4pm. My ex called me, I was so surprised, I answered the call and all he said was that he was so sorry for everything that happened, that he wanted me to return to him, that he loves me so much. I was so happy and went to him, that was how we started living together happily again. Since then, I have made promise that anybody I know that have a relationship problem, I would be of help to such person by referring him or her to the only real and powerful spell caster who helped me with my own problem and who is different from all the fake ones out there. Anybody could need the help of the spell caster, his email: spiritualherbalisthealing@gmail.com or call him +2349055637784 you can email him if you need his assistance in your relationship or anything.
