New Delhi, July 3 (NationPress) A group of Australian researchers has uncovered a set of proteins that could revolutionize the treatment of cancer and diseases associated with aging.
Scientists at the Children's Medical Research Institute (CMRI) in Sydney have found that these proteins are pivotal in regulating telomerase, an enzyme that safeguards DNA during cell division, according to a report by Xinhua news agency.
This discovery elucidates how telomerase not only promotes healthy aging but also accelerates cancer cell proliferation, paving the way for novel therapies aimed at slowing aging or halting cancer by focusing on these newly discovered proteins, the research team stated.
Telomerase plays a key role in preserving the ends of chromosomes, called telomeres, which are essential for maintaining genetic stability.
This enzyme adds DNA to the ends of chromosomes (telomeres), protecting them from degradation.
While telomerase is crucial for the well-being of stem cells and specific immune cells, it is often hijacked by cancer cells, leading to uncontrolled growth.
Researchers at CMRI have now identified a novel collection of proteins that are integral to the regulation of this enzyme.
In a paper published in the journal Nature Communications, the team highlighted that three proteins—NONO, SFPQ, and PSPC1—direct telomerase to the ends of chromosomes; disrupting their function in cancer cells inhibits telomere maintenance, which may halt cancer cell proliferation.
“Our research indicates that these proteins function as molecular traffic controllers, ensuring telomerase reaches the appropriate location within the cell,” stated Alexander Sobinoff, the lead author of the study.
“In the absence of these proteins, telomerase cannot effectively maintain telomeres, a discovery that has profound implications for healthy aging and cancer development,” Sobinoff further added.
Hilda Pickett, head of CMRI’s Telomere Length Regulation Unit and the study’s senior author, emphasized that comprehending the control of telomerase opens new avenues for developing treatments aimed at cancer, aging, and genetic disorders associated with telomere dysfunction.
Point of View
I find this discovery by Australian scientists to be a pivotal advancement in our understanding of cancer and aging. The identification of crucial proteins that regulate telomerase not only sheds light on the complexities of cellular aging but also opens new pathways for targeted cancer therapies. This research underscores the importance of continued investment in scientific exploration for the benefit of public health.
