A research group led by Associate Professor Katsuya Sakai, Researcher Nichole Marcela Rojas-Chaverra, and Professor Kunio Matsumoto of the Cancer Research Institute and Nano-Life Science (WPI-NanoLSI) at Kanazawa University has developed a long-acting, subcutaneously injectable artificial hepatocyte growth factor (HGF) mimetic molecule using a fusion technology of cyclic peptides and protein engineering. They demonstrated in a mouse model that it improves liver fibrosis, lipid accumulation, and inflammation caused by non-alcoholic steatohepatitis (NASH). This research result provides an option for the development of NASH therapeutics as well as a technology for creating growth factor and cytokine mimetic molecules with improved pharmacokinetics.

A research team led by Osaka University developed a theranostics approach to both diagnose and treat certain pancreatic cancer cases. They radioactively labeled a monoclonal antibody targeting glypican-1, which is highly expressed in pancreatic cancer, then administered it to disease model mice. One label, 89Zr, showed high uptake in tumors, which would allow early detection of pancreatic cancer with PET scans. Another label, 211At, was used with alpha therapy to significantly slow tumor growth.

Researchers from Osaka University have revealed that the expression of a specific isoform of GREB1 Is4 is induced in malignant melanoma cells by the melanocyte-specific transcription factor, MITF. They revealed that GREB1 Is4 stimulates pyrimidine biosynthesis and promotes cancer cell proliferation. Furthermore, the anti-tumor effect of antisense nucleic acids against GREB1 showed a potential new modality for malignant melanoma.

Researchers at Kanazawa University report in Cell Reports how alterations in the nuclear pores lead to the degradation of anti-tumor proteins.
03 Aug 2023
The researchers from Osaka University showed how bone erosion caused by cholesteatoma occurs. This study showed that a subset of cells called osteoclastogenic fibroblasts expresses a protein, activin A, which causes the breakdown of the bones. Because of this discovery, novel medical treatments can be developed as first-line management for cholesteatomas.
01 Aug 2023
Researchers from Osaka University found that patients with persistently high levels of urinary albumin excretion in the long term are at high risk of new-onset heart failure. Preventive treatment associated with the lowering of urinary albumin excretion levels in these patients could reduce the risk of later heart failure or mortality.
28 Jun 2023
Researchers from Osaka University have revealed the mechanism by which increased signaling through a pathway associated with a molecule called Wnt leads to the development of liver cancer. They identified a gene called GREB1 as a target of Wnt specifically in liver cancer. This gene alters the function of a protein called HNF4Ī±, leading to the development of cancer. They also showed that treatment of mice with antisense oligonucleotides against GREB1 had significant anti-cancer effects.

Researchers at Kanazawa University report in Nano Letters how high-speed atomic force microscopy leads to insights into processes relevant to Alzheimerā€™s disease. Moreover, the technique is shown to be an excellent tool for studying the effect of drugs against the disease.
11 May 2023
Researchers from Osaka University identified a new protein, R-spondin 3 (RSPO3), that has beneficial effects after ischemic stroke in mice. Specifically, RSPO3 activates the protein LGR4 to trigger a cascade of cellular reactions that decreases inflammation and stimulates the growth of neuronal extensions. Moreover, administrating RSPO3 to mice one day after stroke improved recovery of sensory and motor functions. These findings provide a new target for developing treatments to improve recovery after ischemic stroke.
05 Apr 2023
Researchers from Osaka University found that the COMMD3/8 complex is implicated in the progression of the autoimmune response in a mouse model of rheumatoid arthritis. They identified celastrol, the active compound of a medicinal herb, as an inhibitor of the COMMD3/8 complex. Celastrol blocked the progression of rheumatoid arthritis. Thus, celastrol is a potential lead for developing treatments against rheumatoid arthritis.

New research found that periodontitis, a common gum infection known to worsen other systemic diseases, could also be linked to atrial fibrosis ā€” potentially clarifying its previously unknown connection with atrial fibrillation.
Sleeveless shirt-type wearable device and smartphone application track IBS patientsā€™ sympathetic nervous system activity
12 Jan 2023
An Osaka Metropolitan University research group recorded the autonomic nervous system activity in patients with irritable bowel syndrome (IBS) and healthy subjects using a wearable device and a proprietary smartphone application to record daily life events such as defecation and sleep. As a result, they found that sympathetic nervous system activity was activated in IBS patients from 2 minutes before defecation and continued until 9 minutes after defecation. Further research is expected to improve the quality of life of IBS patients and elucidate the pathophysiology.
04 Jan 2023
Researchers from Osaka University found that dietary supplementation with tricaprin results in coronary artery plaque regression and resolution of symptoms in patients with triglyceride deposit cardiomyovasculopathy, a treatment-resistant form of coronary artery disease. These findings represent a conceptually novel treatment for coronary atherosclerosis that paves the way toward establishing a multi-faceted approach to caring for patients with this condition.
13 Dec 2022
A study by Osaka University has shown that the prevalence of non-communicable diseases, which included hypertension, hyperlipidemia, diabetes, and mental disorders, increased after the Fukushima disaster and the COVID-19 outbreak. These findings emphasize the importance of improving post-disaster health promotion strategies and recommendations.
07 Nov 2022
Researchers led by Osaka University show that a molecule called T-cadherin can be secreted in a soluble form. Soluble T-cadherin interacts with pancreatic insulin-producing Ī² cells via the Notch signaling pathway to promote their proliferation and increase the production of insulin. Recombinant T-cadherin stimulated Notch signaling in isolated mouse pancreatic islets, which contain Ī² cells, indicating that T-cadherin may have therapeutic potential for diabetes.
17 Oct 2022
Researchers from Osaka University have shown that deficiency of the protein Favine can lead to accelerated development of atherosclerosis. Loss of Favine in a mouse atherosclerosis model also led to calcification and thrombus development in the blood vessels of the mice. Prior to this, no mouse models for calcification or thrombus formation existed, hindering atherosclerosis research. This work also identifies Favine and its downstream signaling pathway, known as MEF2C-KLF2, as potential therapeutic targets for atherosclerosis.

DIM damages nuclear membrane in fission yeast
24 Jan 2022
Broccoli may contain advantages beyond nutrition. A molecule found in broccoli, cabbage and more digests down into DIM, a compound with brighter benefits than the name implies, such as inducing cell death in breast, prostate and colon cancer. Now, researchers are beginning to understand the mechanism underpinning this molecular behavior ā€” information that could help elucidate future anti-cancer treatments.

We have succeeded in establishing a mouse model that develops gastric cancer closely resembling advanced human gastric cancer. Using this model, we have discovered gastric cancer stem cells, i.e. Lgr5+ gastric cancer cells, essential for the development, maintenance, and metastasis of cancer. Our study provides an experimental system that enables detailed analysis of highly malignant gastric cancer and is expected to lead to the development of a breakthrough treatment for advanced human gastric cancer.
24 Nov 2021
Researchers from the Osaka City University Graduate School of Medicine have shown in patients with early-stage hepatocellular carcinoma who received cancer treatment that eliminating the hepatitis C virus with a direct-acting antiviral treatment reduces the risk of the liver cancer progression and increases overall patient survival.
