'Magical' royal bee jelly offers promise to combat cancer: Study
New York, July 23 : Royal jelly -- a natural bee product -- long known for its mysterious growth effects on future queen honey bees, while hailed by some as an anti-ageing, cholesterol-lowering super supplement, might also help fight cancer, finds new research.
Royal jelly also called "bee milk", looks like white snot. Besides water, it also contains a combination of proteins and sugars.
The findings showed this "queen magic" affects cell signalling and growth in cancer cells.
However, how this actually happens and its potential benefit to humans, has remained a mystery to scientists.
"The exact structure of the key protein in royal jelly remains unknown. But it is expected to act through the epidermal growth factor (or EGF) receptor -- the main pathway targeted by cancer therapeutics today," Daryl Klein, Assistant Professor at Yale University in Connecticut, US, said in a statement.
Klein's lab studies cell signalling, and how these signals can be "tuned" in different ways.
Using commercial jelly shipped from China, initial studies from Klein's lab have started to resolve the oligomer structure of MRJP-1 (major royal jelly protein).
However, the scientists found that resolution stalled around 11 Angstroms -- not enough to reveal the potential secrets hidden in the jelly.
They fear that the commercially available product may have been the limiting factor.
"We've bought commercial royal jelly, but it goes through a lot of handling -- freezing, thawing and re-freezing -- before it gets to us, which could affect the ultimate resolution we can see in this protein and how we can do functional tests on it," added Tongqing Li, post-doctoral associate at the varsity.
Researchers are now hoping to extract royal jelly from the university's campus to find out "how it modifies cell growth across different species, and how it might modify cancer cell signalling," Klein said.

K'taka Minister demands international status for Hubballi, Belagavi airports after Madurai move
Bengaluru (PTI): Karnataka Infrastructure Development Minister M B Patil on Wednesday expressed displeasure over the Centre declaring Madurai airport as an international airport while not extending a similar status to Hubballi and Belagavi airports in Karnataka, calling the move "discriminatory and unacceptable".
The minister said the central government may have taken this decision keeping the upcoming Tamil Nadu elections in mind.
However, its indifferent attitude towards Karnataka’s demand is questionable, he added.
"The Narendra Modi-led central government has declared Madurai Airport in Tamil Nadu as an international airport but has not taken a similar decision regarding Hubballi and Belagavi airports in Karnataka. This reflects a discriminatory approach and is not acceptable. How can it be butter for them and lime for us?” he questioned in a statement.

The Cabinet on Tuesday approved the proposal to declare Madurai airport as an international airport.
Madurai is a prominent city in Tamil Nadu, and Union Minister Ashwini Vaishnaw said the decision was taken keeping in view the aspirations of the people of that city.
Patil recalled that a letter had been written on June 24, 2025, to Union Civil Aviation Minister Ram Mohan Naidu, requesting that Hubballi and Belagavi airports be upgraded to international status, as this would greatly benefit the North Karnataka region.
"In this context, Union Minister and Dharwad MP Pralhad Joshi, Belagavi MP Jagadish Shettar, and Haveri MP Basavaraj Bommai should raise their voices and stand firmly for the interests of the State," he urged.
The minister stressed that at least one of the two airports — Hubballi or Belagavi — should be declared an international airport.
"If both are upgraded, it would be even more welcome. The central government must recognise the State’s requirement," Patil added.
