New York, Nov 19: Researchers have discovered a new protein that could reduce the spread of cancer by binding the cancer cells together and allowing them to invade tissues.

The study conducted by the researchers from University of Guelph, Ontario, has identified a protein called cadherin-22, a potential factor in cancer metastasis or the spread of cancer.


The protien also decreased the adhesion and invasion rate of breast and brain cancer cells by up to 90 per cent.

“Cadherin-22 could be a powerful prognostic marker for advanced cancer stages and patient outcomes,” said lead author Jim Uniacke, a professor at the varsity.

“If you can find a treatment or a drug that can block cadherin-22, you could potentially prevent cancer cells from moving, invading and metastasizing.”

The study, published in the journal Oncogene, looks specifically at hypoxia, a condition in which the tissues receive less oxygen.

The researchers found that it is precisely under conditions of low oxygen that cancer cells trigger the production of cadherin-22, putting in motion a kind of protein boost that helps bind cells together, enhancing cellular movement, invasion and likely metastasis.

Studying breast and brain cancer cells in a hypoxia incubator, the researchers discovered that cadherin-22 is involved in this process to enable the spread of cancer cells.

For both cancer types, the research team used molecular tools to reduce the amount of cadherin-22.

They placed the human cancer cells into the incubator and lowered the oxygen to a level comparable to that in a tumour. The cells failed to spread.

“One very powerful and common tool in cell and molecular biology labs is, you can remove a protein from a cell and see how that cell behaves without it.

“We culture our cancer cells in this very low-oxygen environment, and they start behaving like they are inside a low-oxygen tumour,” Uniacke added. (IANS)

Narakasura's death is celebrated as 'Naraka Chaturdashi' popularly known as Choti Diwali

Diwali is arguably one of the most auspicious and celebrated holidays in South Asia. It is celebrated over the span of five days, where the third is considered most important and known as Diwali. During Diwali people come together to light, lamps, and diyas, savour sweet delicacies and pray to the lord. The day has various origin stories with the main them being the victory of good over evil. While the North celebrates the return of Lord Rama and Devi Sita to Ayodhya, the South rejoices in the victory of Lord Krishna and his consort Satyabhama over evil Narakasura.

Narakasura- The great mythical demon King

Naraka or Narakasur was the son of Bhudevi (Goddess Earth) and fathered either by the Varaha incarnation of Vishnu or Hiranyaksha. He grew to be a powerful demon king and became the legendary progenitor of all three dynasties of Pragjyotisha-Kamarupa, and the founding ruler of the legendary Bhauma dynasty of Pragjyotisha.

Safety-pins with charms

For all the great inventions that we have at hand, it is amazing how we keep going back to the safety pin every single time to fix everything. Be it tears in our clothes, to fix our broken things, to clean our teeth and nails when toothpicks are unavailable, to accessorize our clothes, and of course, as an integral part of the Indian saree. Safety pins are a must-have in our homes. But how did they come about at all?

The safety pin was invented at a time when brooches existed. They were used by the Greeks and Romans quite extensively. A man named Walter Hunt picked up a piece of brass and coiled it into the safety pin we know today. He did it just to pay off his debt. He even sold the patent rights of this seemingly insignificant invention just so that his debtors would leave him alone.

Sesame oil bath is also called ennai kuliyal in Tamil

In South India, Deepavali marks the end of the monsoon and heralds the start of winter. The festival is usually observed in the weeks following heavy rain, and just before the first cold spell in the peninsula. The light and laughter that comes with the almost week-long celebration are certainly warm to the bones, but there is still a tradition that the South Indians follow to ease their transition from humidity to the cold.

Just before the main festival, the family bathes in sesame oil. This tradition is called 'yellu yennai snaana' in Kannada, or 'ennai kuliyal' in Tamil, which translates to 'sesame oil bath'. The eldest member of the family applies three drops of heated oil on each member's head. They must massage this oil into their hair and body. The oil is allowed to soak in for a while, anywhere between twenty minutes to an hour. After this, they must wash with warm water before sunrise.
