New compound found which kills cancer without harming healthy cells

Cancer is considered to be one of the most deadly diseases all over the world. According to World Health Organisation, it is the second leading cause of death globally, and was responsible for 8.8 million deaths in 2015. Worldwide, nearly 1 in 6 deaths is due to cancer.

 But now a group of researchers have found a compound that directly makes cancer cells commit suicide while sparing healthy cells.

The new treatment was directed against acute myeloid leukemia (AML) cells but may also have potential for attacking other types of cancers.

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 cancerin 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.

Even though Karnataka recorded the lowest number of Covid deaths in April since the virus struck first in 2020, the state is recording a rise in the positivity rate (1.50 per cent). Five people died from the Covid infections in April as per the statistics released by the state health department. In March, the positivity rate stood around 0.53 per cent. In the first week of April it came down to 0.38 per cent, second week registered 0.56 per cent, third week it rose to 0.79 per cent and by end of April the Covid positivity rate touched 1.19 per cent.

on an average 500 persons used to succumb everyday in the peak of Covid infection, as per the data. Health experts said that the mutated Coronavirus is losing its fierce characteristics as vaccination, better treatment facilities and awareness among the people have contributed to the lesser number of Covid deaths.

During the 4th and 6th of April two deaths were reported in Bengaluru, one in Gadag district on April 8, two deaths were reported from Belagavi and Vijayapura on April 30. The first Covid case was reported in the state in March 2020 and three Covid deaths were recorded in the month. In the following month 21 people became victims to the deadly virus, and May 2020 recorded 22 deaths. The death toll recorded everyday after May crossed three digits. However, the third wave, which started in January 2
