What are ‘zombie cells’ and are they good for you?

  • Ends of chromosomes are called telomeres that protect genetic material.
  • Each time cells divide, telomeres shorten and weaken.
  • Cells avoid turning cancerous by becoming zombie-like in process called cellular senescence.

If the ends of our chromosomes are damaged, “zombie cells” can take birth. These cells are alive but unable to function, according to a new study published in Nature Structural and Molecular Biology.

The ends of chromosomes are called telomeres that protect the genetic material. They form a protective lid on the chromosomes.

Each time cells divide, telomeres shorten and weaken. With age, therefore, telomeres lose their strength as the cells keep dividing. This means DNA becomes more prone to damage.

This damage can lead to gene mutation which can further result in cancer.

Cells avoid turning cancerous by becoming zombie-like in a process called cellular senescence.

These senescent cells are resistant to death. They can be good for health by inviting immune cells to fight any cancer cells.

However, they can also hinder tissue healing and immune functions by releasing chemicals that cause tumour growth.

Researchers decided to figure whether damaged telomeres are the only reason for cell senescence.

Findings confirmed that telomere damage was enough to trigger zombie cells even when it was not shortened. 

It is important because senescence can be triggered prematurely and cause age-related illnesses like cardiovascular disease, immunodeficiency, and cancer.

Therefore, telomeres are not only alerting bells indicating that a cell has divided too many times but also signals harmful levels of oxidative stress.

Romina Khurshid Alam, the Coordinator of the Prime Minister’s Office, underlined the significance of gender-inclusive climate resilience during her presentation on climate change. This was done in light of the fact that Pakistan is seeing a worsening of the consequences of climate change.

When Alam was having a conversation with a group of people from the Green Tech Hub at NUST and UN-Women, he brought up the idea that women who live in rural regions are particularly vulnerable, but that they are also quite important in the process of creating solutions that are sustainable.

It was discussed by the delegation that the Green Tech Hub, which was formed in October at NUST, should be enlarged in order to foster innovation in the disciplines of climate adaptation and renewable energy. This was done in order to encourage innovation in these domains. For the purpose of bolstering the initiative, Romina Alam has committed to give assistance in the search of collecting funds and collaborations.

The necessity of providing women with the knowledge and tools necessary to create resilience was emphasized by Romina Alam, who also called for climate strategies that are inclusive and take into account the specific issues that women face and the potential that they have to take on leadership roles.
