Lung cancer: Plant compound berberine shows promise - Medical News Today
- Lung cancer is the second most common type of cancer in the world, with 1.8 million people dying from the condition in 2020.
- Researchers from the University of Technology Sydney (UTS) found a plant compound to be effective at stopping the growth of lung cancer cells in a laboratory setting.
- Researchers plan to further test their findings in preclinical animal models of lung cancer.
Lung cancer is the second most common type of cancer in the world. There were more than 2.2 million new diagnoses of lung cancer around the world in 2020. And that same year, globally about 1.8 million people died from lung cancer.
While there is currently no cure for lung cancer, scientists are working on treatment options. Some of these scientists are at the University of Technology Sydney (UTS), where a new study found a natural herbal compound called berberine stops the growth of lung cancer cells in a laboratory setting.
The authors report the results in a paper that recently appeared in the journal Pharmaceutics.
Berberine is a naturally-occurring plant compound used in
Over the years, research shows berberine to be effective in helping people with
Researchers have also identified berberine as a
According to Dr. Kamal Dua, a senior lecturer in Pharmacy and Senior Research Fellow, Australian Research Centre in Complementary and Integrative Medicine (ARCCIM), Faculty of Health at the University of Technology Sydney (UTS), and lead author of this study, berberine inhibits the two key processes of cancer progression — cell proliferation and migration.
"Mechanistically, this is possible by inhibition of key genes such as P53, PTEN, and KRT18 and proteins such as AXL, CA9, ENO2, HER1, HER2, HER3, PRGN, PDGF-AA, DKK1, CTSB, CTSD, BCLX, CSF1, and CAPG associated with cancer cell proliferation and migration," he explained.
For this current study, a research team including Dr. Dua, Dr. Keshav Raj Paudel, Prof. Philip M. Hansbro, and Dr. Bikash Manandhar from UTS, together with collaborators from the International Medical University in Malaysia and Qassim University in Saudi Arabia, examined how berberine could be used to treat lung cancer.
"As berberine has poor solubility and bioavailability, its clinical application is limited," Dr. Dua explained for MNT. "The main purpose of this study is to improve the physicochemical parameter of berberine by formulating it into liquid crystalline nanoparticles and study its in vitro anticancer potential against human adenocarcinomic alveolar-basal epithelial cells,
The research team developed an advanced drug delivery system encapsulating berberine into tiny soluble and biodegradable balls. These liquid crystalline
At the conclusion of the study, the research team found that berberine helped stop the creation of
Additionally, berberine helped modulate genes involved with oxidative stress and inflammation, and also helped reduce premature
"We proved that using the nanotechnology approach, it is possible to enhance the property of compounds with various problems related to solubility, cellular uptake, and therapeutic efficacy," Dr. Dua explained. "In comparison to other published literature using a high dose of berberine pure compound to show anti-cancer potential, our berberine-liquid crystalline nanoparticles showed the same activist in a five-fold less dose, which clearly shows the advantage of nanoformulation."
To further test these findings, Dr. Dua said he plans to use a new research platform to carry out in-depth studies using preclinical animal models of lung cancer.
"Further pharmacokinetic and anti-cancer studies of berberine nanoformulations in 'in vivo' animal models could elucidate its potential benefits in the treatment of lung cancer and develop it as a therapeutic drug dosage form," he explained.
"Once we validate the anti-cancer potential of berberine nanoformulation in a pre-clinical animal model, the next step would be to move towards the clinical trial where we are already in discussion with a few Sydney-based companies," Dr. Dua noted.
Additionally, Dr. Dua said the potential of berberine being used to stop lung cancer from recurring needs validation: "Although we have not yet investigated this, we are planning to do it as a part of future studies, and we also believe that berberine nanoformulation will show promising activity."
Dr. Osita Onugha, thoracic surgeon and assistant professor of thoracic surgery at Saint John's Cancer Institute at Providence Saint John's Health Center in Santa Monica, CA, told MNT it is always promising when researchers find new options for the treatment and prevention of cancer:
"Berberine is part of Eastern medicine, and so it's not something that we traditionally use in Western medicine. I think it's interesting and intriguing because […] we're looking at things [we] know have some benefit in Eastern medicine, [and are putting them] into a study [to] help translate it to Western medicine."
"It's always promising, but it is in a lab and a lot of things we find in a lab do not necessarily translate to the treatment of patients," Onugha continued. "I think the next thing to do is […] to do some clinical trials on patients […] and figure out the dosing."
