New York: Indian-origin scientists and a team of researchers said, a natural extract derived from Neem tree can be used for treating lethal pancreatic cancer.

The results revealed that nimbolide, an active molecule isolated from Neem tree (Azadirachta indica), can stop pancreatic cancer’s growth and spread without harming normal, healthy cells.

“The promise nimbolide has shown is amazing, and the specificity of the treatment towards cancer cells over normal cells is very intriguing,” said Rajkumar Lakshmanaswamy, associate professor at Texas Tech University Health Sciences Center El Paso in the US.

Pancreatic cancer has the highest mortality rate of all cancers with 94 percent of patients dying within five years of diagnosis.

The cancer grows quickly and there are currently no effective treatments available.

In the study, Lakshmanaswamy and colleagues observed that nimbolide was able to reduce the migration and invasion capabilities of pancreatic cancer cells by 70 percent meaning the cancerous cells did not become aggressive and spread.

And that is promising, the researchers said.

In humans, this migration and invasion or metastasis of pancreatic cancer to other regions of the body is the chief cause of mortality.

Nimbolide treatments also induced cancer cell death, causing the size and number of pancreatic cancer cell colonies to drop by 80 percent.

“Nimbolide seems to attack pancreatic cancer from all angles,” Lakshmanaswamy said.

What is more, the Neem compound did not harm healthy cells in both the in vitro and in vivo experiments.

“Many people in India actually eat neem and it doesn’t have harmful side effects, which suggests that using nimbolide for pancreatic cancer will not cause adverse effects like chemotherapy and radiation typically do,” study lead author Ramadevi Subramani, postdoctoral researcher at Texas Tech University Health Sciences Centre, said.

The findings appeared in the journal Scientific Reports.

While the results are promising, Lakshmanaswamy said there is still a long way to go before nimbolide can be used to treat pancreatic cancer in humans.

The researchers said they plan to continue researching the anticancer mechanisms behind the plant extract.(image: stylecraze.com)(IANS)

Males Have Higher Risk of Suffering from Cancer: Study

Researchers explain why cancer risk is higher in males

DNA differences between men and women may explain why cancer risk is higher in males, according to a new study.

In findings published in the Journal of the National Cancer Institute, researchers have reported that loss of function in certain genes of the sex-determining Y chromosome, which is present only in men, may cause them to have an elevated risk for cancer.

Using data from 9,000 individuals, the researchers studied Y-chromosome gene function in patients with various types of cancer. The findings showed that cancer risk increases with loss of function of six key Y-chromosome genes in various types of cells.

“Recent studies have shown that complete loss of the Y chromosome, which is essential to foetal sex differentiation, occurs, with aging, in the cells of some men,” said study author Juan Ramon Gonzalez from Barcelona Institute for Global Health in Spain.

“Although the loss of the Y chromosome has previously been associated with higher incidence of cancer, the causes of this association are poorly understood,” Gonzalez added.

These six Y-chromosome genes are involved in cell-cycle regulation, the failure of which can lead to tumour development.

According to the study, understanding the biological differences between men and women in cancer is crucial for the development of personalised lines of treatment and prevention.

“Men are not only at higher risk of cancer than women, they also face a worse prognosis. In fact, these differences partially account for the lower life expectancy of men,” Gonzalez added.

According to the researchers, although men may be more exposed to carcinogens due to the type of work they do and at higher risk because they are less likely to consult a doctor, the study has shown that there are also biological factors that increase cancer risk among men.

“In fact, it seems that one of these factors can be found in the Y chromosome, the very essence of maleness,” said study lead author Alejandro Caceres.

Suppression of the Y chromosome can occur as a result of loss of function in the chromosome, which would explain previous findings, or as a result of other mechanisms mediated by the chemical (epigenetic) inactivation of the same regions, the research said.

“Certain environmental exposures, for example to tobacco or other harmful substances, could affect chromosome function and lead to epigenetic modifications,” Gonzalez said. (IANS)
