(Press-News.org) Lawsonia inermis is best known for making henna, a versatile dye that is used to change the color of skin and clothes. Now, researchers from Osaka Metropolitan University have found another use for the pigments extracted from the dye: treating liver disease.
Specifically, they could treat liver fibrosis, a disease that causes excess fibrous scar tissue to build up in the liver as a result of chronic liver injury caused by lifestyle choices such as excessive drinking. Patients with liver fibrosis have increased risks of cirrhosis, liver failure, and cancer. Despite 3–4% of the population having the advanced form of the disease, treatment options remain limited.
One potential treatment for the disease involves hepatic stellate cells (HSCs). Usually, these cells maintain balance in the liver; however, when too many are activated, such as during liver injury, they produce excessive fibrous tissue and collagen, disrupting normal liver function.
A research group led by Associate Professor Tsutomu Matsubara and Dr. Atsuko Daikoku at the Graduate School of Medicine, Osaka Metropolitan University, developed a chemical screening system that identifies substances that directly act on activated HSCs. Using the system, they identified Lawsone, a chemical component from Lawsonia inermis—also known as the henna tree—as a potential inhibitor of HSC activation.
When the researchers administered Lawsone, the mice that received the treatment showed reductions in markers of liver fibrosis, such as YAP, αSMA, and COL1A. They also found upregulated cytoglobin, a marker associated with antioxidant functions in HSCs, suggesting that the HSCs were reverting back toward the non-fibrotic, quiescent type.
The professors believe that by making drugs based on Lawsone, they could create the first treatment that controls and even improves fibrosis. “We are currently developing a drug delivery system capable of transporting drugs to activated HSCs and ultimately hope to make it available for patients with liver fibrosis,” Matsubara said. “By controlling fibroblast activity, including HSCs, we could potentially limit or even reverse the effects of fibrosis.”
The study was published in Biomedicine & Pharmacotherapy.

KIST demonstrates world's first ultra-precise, ultra-high-resolution distributed quantum sensor with 'entangled light'
2025-10-27
Precise metrology forms a fundamental basis for advanced science and technology, including bioimaging, semiconductor defects diagnostics, and space telescope observations. However, the sensor technologies used in metrology have so far faced a physical barrier known as "standard quantum limit". A promising alternative to surpass this limit is the distributed quantum sensor-A technology that links multiple spatially separated sensors into a single, large-scale quantum system, thereby enabling highly precise measurements. To date, efforts ...
Liver transplantation utilizing grafts donated after medical assistance in dying is feasible and has outcomes comparable to standard donation
2025-10-27
October 27, 2025 – Organ donation following medical assistance in dying (MAiD), also known as euthanasia, is a relatively new practice both in North America and worldwide. A first comparison of liver transplantation using organs donated after MAiD in Canada has shown good patient survival with outcomes similar to standard donation after circulatory death. The findings from the new study in the Journal of Hepatology, published by Elsevier, highlight that this practice can help to meet the increasing demand for organs by expanding the donor pool, thereby saving more lives.
As of 2025, organ donation following ...
Canada is failing the rising numbers of youth who use opioids
2025-10-27
Youth opioid use is increasing in Canada, as are related emergency department visits and deaths, yet governments are not providing adequate support to address this public health crisis, argue the authors of a CMAJ (Canadian Medical Association Journal) editorial https://www.cmaj.ca/lookup/doi/10.1503/cmaj.251682.
“If this crisis is not properly addressed now, Canada’s health systems will play a part in perpetuating the opioid crisis for decades to come,” write Dr. Shannon Charlebois, medical editor, CMAJ, and Dr. Shawn ...
Opioid prescribing for pain is declining in Canada
2025-10-27
Efforts to promote safer opioid prescribing in Canada appear to be having an effect, as new research in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.250670 shows a decrease in opioid dispensing between 2018 and 2022.
In the early 2000s, use of prescription opioids to treat acute and chronic noncancer pain increased substantially in Canada, and with it came a rise in opioid-related harms. The availability of more opioid products, coupled with aggressive marketing of these drugs, ...
Can inpatient care help address overdose crisis?
2025-10-27
Is expanding hospital inpatient, or bed-based, care a way to help address the overdose crisis? An analysis article in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.240955 describes the RE-AIM framework (Reach, Effectiveness, Adoption, Implementation, and Maintenance), which can help provinces determine whether bed-cased care is effective.
British Columbia and Alberta, the two provinces with the highest rate of overdose deaths, are focusing more on bed-based care. British Columbia is considering expanding capacity, and Alberta is planning to ...
Discovering six new bat species is a treat for museum researchers
2025-10-27
Just in time for Halloween, six new bat species have been discovered by researchers from the Royal Ontario Museum (ROM), Field Museum in Chicago, and Lawrence University in Wisconsin. This nocturnal – and slightly spooky – group of mammals is incredibly diverse, and the discovery adds to the thousands of known bat species.
Formally described as new species through the examination of physical and genetic characteristics, these six new species from the Philippines are commonly known as tube-nosed bats.

National emergency wakeup call as SEND support system crisis worsens – latest analysis shows
2025-10-27
The special educational needs and disabilities (SEND) system, already known to be in deep trouble, now faces ‘a worsening crisis’ which, say experts, puts the UK on the brink of a national emergency.
A new Child of the North (CotN) report update highlights that schools still lack skills, resources and access to support services, face delays in receiving statutory individual education, health and care plans (EHCP), and experience severe school SEND absences.
‘Addressing the SEND crisis update: Implementing what works in ...
New drug-eluting balloon may be as safe and effective as conventional metal stents for repeat percutaneous coronary interventions
2025-10-26
A new drug-eluting balloon can perform just as well as the standard treatment for patients with coronary in-stent restenosis (ISR) undergoing repeated percutaneous coronary intervention (PCI). These breakthrough findings of an international clinical trial led by a Mount Sinai researcher could transform the way this patient population is treated.
This is the first U.S.-regulated, and largest randomized, trial to compare a balloon coated with the drug sirolimus against the current standard of care for ISR, which includes both repeat stenting and balloon angioplasty. It could lead to a safer and simpler alternative for patients who need ...
Effectiveness and cost-effectiveness of automated external defibrillators in private homes
2025-10-25
About The Study: In this study, automated external defibrillators (AEDs) in private homes were effective at improving outcomes for patients with cardiac arrest and a shockable rhythm. Given the relative rarity of cardiac arrest at a given home, general purchase of AEDs for individual private homes cannot be considered cost-effective at the current pricing of AEDs.
