Washington D. C. [U. S. A], Oct. 10 (ANI): Cancer is considered to be one of the most deadly diseases all over the world.
Late-stage presentation and inaccessible diagnosis and treatment are pretty common. This disease involves abnormal growth of cells that have the potential to spread in different parts of the body and kill all the healthy cells.
While talking about the research, Evripidis Gavathiotis, Ph. D. , associate professor of biochemistry and of medicine and senior author of the study, said, "We're hopeful that the targeted compounds we're developing will prove more effective than current anti-cancer therapies by directly causing cancer cells to self-destruct. Ideally, our compounds would be combined with other treatments to kill cancer cells faster and more efficiently -- and with fewer adverse effects, which are an all-too-common problem with standard chemotherapies. "
This compound can be very useful for a country like India, which is seeing a growth in cancer cases.
Every year nearly 25,000 children are diagnosed with cancer in India and around 9000 of these have leukemia.
According to Indian Council of Medical Research (ICMR), Cancer cases in India are expected to jump from around 14 lakh in 2016 to over 17. 3 lakh by 2020.
While deaths due to cancer are projected to go up from 7. 36 lakh to over 8. 8 lakh in the next four years.
Talking about the research this compound combats cancer by triggering apoptosis, an important process that rids the body of unwanted or malfunctioning cells. Apoptosis trims excess tissue during embryonic development, for example, and some chemotherapy drugs indirectly induce apoptosis by damaging DNA in cancer cells.
Apoptosis occurs when BAX -- the "executioner protein" in cells -- is activated by "pro-apoptotic" proteins in the cell. Once activated, BAX molecules home in on and punch lethal holes in mitochondria, the parts of cells that produce energy. But all too often, cancer cells manage to prevent BAX from killing them.
Dr. Gavathiotis noted, "Our novel compound revives suppressed BAX molecules in cancer cells by binding with high affinity to BAX's activation site. BAX can then swing into action, killing cancer cells while leaving healthy cells unscathed. "
Meanhwile, study's lead author Denis Reyna, M. S. , a doctoral student in Dr. Gavathiotis' lab shared, "A compound dubbed BTSA1 (short for BAX Trigger Site Activator 1) proved to be the most potent BAX activator, causing rapid and extensive apoptosis when added to several different human AML cell lines.
The researchers tested BTSA1 in blood samples from patients with high-risk AML. Strikingly, BTSA1 induced apoptosis in the patients' AML cells but did not affect patients' healthy blood-forming stem cells.
Importantly, the mice treated with BTSA1 showed no evidence of toxicity.
The research also noted that AML cells from patients contained significantly higher BAX levels compared with normal blood cells from healthy people.
The study was published in journal Nature. (ANI)
