- Research team led by Professor Jo Dong-gyu publishes a paper in Journal of Extracellular Vesicles
- Professor Jo Dong-gyu's research team has published a new research result that can be applied to the prevention and treatment of osteoporosis. The research team confirmed the therapeutic effect in osteoporosis through exosomes derived from adipose stem cells and investigated the mechanism of action that inhibits the differentiation into osteoclasts. In bone tissue of osteoporotic patients, differentiation of osteoclasts by RANKL is over-activated, and the expression level of Osteoprotegerin, a natural inhibitor of RANKL, is low. In addition, miRNA (microRNA) is an important factor regulating bone function and metabolism, and it has been reported that the expression pattern of miRNA in the serum of osteoporosis patients is different from that of normal people. The team confirmed that the decreased bone density was restored when adipose stem cell-derived exosomes were administered to an animal model of osteoporosis induced by resection of the ovaries for two weeks. In addition, it was confirmed that the adipose stem cell-derived exosome inhibits the differentiation of osteoclasts and promotes the migration of bone marrow mesenchymal stem cells. Component analysis was conducted to identify the mechanism of action of adipose stem cell-derived exosomes, and it was confirmed that Osteoprotegerin and various miRNAs, which are low in expression in osteoporosis, were present in the exosomes. In the case of exosomes deficient in osteoprotegerin, it was revealed that the therapeutic effect of adipose stem cell-derived exosomes was dependent on Osteoprotegerin through the absence of an osteoclast inhibitory effect and no therapeutic effect on osteoporosis. In addition, it was suggested as a new therapeutic target for osteoporosis by confirming that osteoclast differentiation was inhibited when miR-21-5p and let-7b-5p were overexpressed. In addition, it was found that when adipose stem cell-derived exosomes were administered intravenously, they were effectively delivered to bone tissue. Based on these results, the team presented a potential as a new therapeutic agent for osteoporosis by delivering therapeutic factors to bone tissue using adipose stem cell-derived exosomes in osteoporosis and inhibiting the differentiation of osteoclasts. Professor Jo Dong-gyu said, “It is speculated that cytokines and miRNAs contained in adipose stem cell-derived exosomes are related to osteoclast and osteoclast differentiation. This study may suggest a new direction for overcoming osteoporosis.” The research results were published in the October issue of ‘Journal of Extracellular Vesicles’ (IF 25.841), a world-renowned journal. This research was conducted through joint research with Professor Jo Dong-gyu's research team and the research team of Cho Yong-woo of Hanyang University. The research was supported by the Ministry of Science and ICT (Minister Hye-sook Lim), Mid-career researcher grant fundedby the National Research Foundation (Chairman Gwang-bok Lee), the Leading Research Center(MRC), and the Ministry of Food and Drug Safety.

- Research professor Yi Sang Ah publishes a paper in Advanced Materials
- Research Professor Lee Sang-ah(1st author) and Professor Lee Ki-beom Lee's research team at Rutgers New Jersey State University wrote a review paper on the latest bioengineering technology in organoid research. Organoids, organ analogues that are differentiated from stem cells in three dimensions, are used for drug development, disease treatment, and artificial organ development. However, due to various technical limitations, it is difficult to make it identical to an actual organ, and many studies are being attempted worldwide to overcome this issue. This paper deals with various cutting-edge technologies for making organoids similar to organs in the human body and applying them to clinical treatment. The research has been supported the Presidential Post Doc. Fellowship funded by National Research Foundation of Korea and was published in a world-renowned academic journal, Advanced Materials (IF 30.849) with an early view on September 24.

- Professor Jo Dong-gyu's research team publishes a paper in Theranostics
- A research team led by Professor Jo Dong-gyu (first author: Han Jihoon, combined Master/Ph.D course) revealed the mechanism on how Presenilin-1 mutations, which are known to be the main cause of hereditary Alzheimer's dementia, affect mitochondria. This study was conducted based on the fact that mitochondrial dysfunction and oxidative stress are detected in the early stages of Alzheimer's disease and that Presenilin-1 is present in various intracellular organelles including mitochondria. The team found that the mutation of Presenilin-1 abnormally increases the binding of ER and mitochondria by increasing the expression of ATL2, and that the expression level of ATL2 is increased in Alzheimer's patients and Alzheimer's mouse model brains. This study was carried out with the support of the Ministry of Science and ICT's Mid-career research grant and the Leading Research Center (MRC), and was published in the September issue of Theranostics (IF 11.56), a world-renowned academic journal. * Title: Alzheimer’s disease-causing presenilin-1 mutations have deleterious effects on mitochondrial function

- Professor Chung Ka Young's research team publishes a paper in PNAS
- Professor Chung Ka Young's research team (first author Dr. course Park Ji Young, M.S. course Yun Min Woo) announced that they have identified the mechanism how Arrestin scaffolds ERK signaling proteins through joint research with Professor Jinpeng Sun of Shandong University. Arrestin is known to promote ERK signaling as a major sub-signaling protein of the G protein-coupled receptor. However, the exact mechanism was unknown. Therefore, the research team studied the structural principle that Arrestin and ERK signaling proteins combine to reveal the principle that Arrestin promotes ERK signaling. The research was carried out with the support of the Ministry of Science, ICT and Future Planning Mid-career Research Grant and the Leading Research Center (MRC), and was published in the September issue of Proceedings of the National Academy of Sciences of the USA (IF 11.205).

- Former School of Pharmacy Student Presidents publish papers in world-renowned journals
- Professor Kim In Su's research team published papers on the July issue of 'Organic Letters (IF = 6.091, JCR ranking = 7.0%)', a world-renowned scientific journal in the field of chemistry (1st author: Park Min Seo, master's course, co-first author: Moon Kyeongwon, 6th grade undergraduate) and on the Auguest issue of 'The Journal of Organic Chemistry (IF = 4.335, JCR ranking = 15.7%)' (1st author: Byun Youjung, master's course). The findings of Professor Kim In Su's research team are development of synthesis and transformation reaction on a major heterocyclic skeleton in pharmaceuticals through the introduction of novel functional groups. The N-heterocyclic skeleton is known as the core skeleton of pharmaceuticals and natural products. The team published the results of synthesizing indazole and dihydrocinnolinone structures, known as key pharmacological groups, through intramolecular cyclization after linking azobenzene and vinylene carbonate structures using a very small amount of a rhodium catalyst in the journal, 'Organic Letters'. The indazole structure is the core skeletal structure of drugs with anti-inflammatory, vascular homeostasis, anticancer and antiemetic activities, and the dihydrocinnolinone structure is the core skeletal structure of drugs with antibiotic and antifungal activities. In addition, another Professor Kim In Su's research team developed a radical generation under eco-friendly conditions that do not use metal, and further developed these reaction conditions on introducing alkyl and acyl groups into carbon-hydrogen bonds in benzoxazinone and published in The Journal of Organic Chemistry. The Benzoxazinone structure is known to have anticancer and antibiotic activities, and has a skeletal structure similar to that of a pyruvate kinase activator. The findings have also proposed a new molecular structure synthesis method by expanding the scope of application of various heterocyclic heterocycles to compounds having a parent nucleus through heteroarylation of the benzoxazinone structure.

- JPR publishes Professor Lee Hyo-Jong's paper as a cover of its August issue
- A research team led by Professor Lee Hyo-Jong (First author, Ph.D course Hwang Su Jung ) announced that the team has developed an anti-cancer treatment substance that simultaneously inhibits the growth of cancer cells and the formation of blood vessels in the cancer microenvironment through a joint research with Professor Park Yo-Han of Inje University. Hypoxia-inducible factor-1α (HIF-1α) protein is a key factor which regulates cancer cell division, angiogenesis, invasion and metastasis in the cancer microenvironment. Therefore, research on the development of its inhibitors is being actively conducted. Melatonin is a natural hormone produced by the pineal gland in the body and exhibits anticancer activity by regulating HIF-1α, but has a problem of low bioavailability. Accordingly, the research team derived a melatonin analogue (NB-5-MT) that improved the absorption rate into cancer cells with remarkably low toxicity through minimal chemical structural modification from the natural hormone melatonin, and NB-5-MT It was confirmed through animal experiments that it inhibits not only the growth but also the formation of blood vessels in the cancer microenvironment. Furthermore, it was found that NB-5-MT exhibited superior effects in not only improved cell uptake, but also decreased HIF-1α protein expression, decreased transcription of HIF-1α target gene, decreased reactive oxygen species (ROS), and suppressed tumor size and metastasis. Professor Lee Hyo-Jong said, “It is very meaningful to discover an improved melatonin-better that compensates for the shortcomings of melatonin, a natural anticancer hormone, and maximizes its effects. It presented the possibility of developing a dual-action new drug that simultaneously inhibits cancer cells and their surrounding microenvironment, and is expected to be used in vascular diseases such as macular degeneration.” This research was carried out with the support of the Ministry of Science and ICT's Support for Outstanding New Researchers, the Gene-Donguibogam Project based on Traditional Natural Products, and the Project for Fostering the Next Generation in Science and Engineering. It is published as a cover paper in the August issue, JOURNAL OF PINEAL RESEARCH. (IF 13.007, JCR ranking 3.09%) * Title: Enhanced anti-angiogenic activity of novel melatonin-like agents
