CTLA4-Ig protects tacrolimus-induced oxidative stress via inhibiting the AKT/FOXO3 signaling pathway in rats
Long Jin, Nan Shen, Xinyu Wen, Weidong Wang, Sun Woo Lim, Chul Woo Yang
Korean J Intern Med. 2023;38(3):393-405. Published online April 28, 2023
Background/Aims: Although the conversion from tacrolimus (TAC) to cytotoxic T-lymphocyte-associated antigen 4-immunoglobulin (CTLA4-Ig) is effective in reducing TAC-induced nephrotoxicity, it remains unclear whether CTLA4-Ig has a direct effect on TAC-induced renal injury. In this study, we evaluate..

Alleviation of renal ischemia/reperfusion injury by exosomes from induced pluripotent stem cell-derived mesenchymal stem cells
Sun Woo Lim, Kyung Woon Kim, Bo Mi Kim, Yoo Jin Shin, Kang Luo, Yi Quan, Sheng Cui, Eun Jeong Ko, Byung Ha Chung, Chul Woo Yang
Korean J Intern Med. 2022;37(2):411-424. Published online September 16, 2021
Background/Aims: Renal ischemia followed by reperfusion (I/R) is a leading cause of acute kidney injury (AKI), which is closely associated with high morbidity and mortality. Studies have shown that induced pluripotent stem cell (iPSC)-derived mesenchymal stem cells (iMSCs) exert powerful therapeutic..

Human kidney organoids model the tacrolimus nephrotoxicity and elucidate the role of autophagy
Jin Won Kim, Sun Ah Nam, Eunjeong Seo, Jong Young Lee, Dohui Kim, Ji Hyeon Ju, Sun Woo Lim, Hong Lim Kim, Hyung Wook Kim, Chul Woo Yang, Jin Kim, Dong Sung Kim, Yong Kyun kim
Korean J Intern Med. 2021;36(6):1420-1436. Published online July 27, 2021
Background/Aims: Tacrolimus has been used as an immunosuppressive agent in organ transplantation. Despite the therapeutic benefits, tacrolimus’s use is limited due to its nephrotoxicity. To reduce tacrolimus nephrotoxicity, effective humanized experimental models may be helpful. Here, we modeled t..

Water-soluble coenzyme Q10 provides better protection than lipid-soluble coenzyme Q10 in a rat model of chronic tacrolimus nephropathy
Sheng Cui, Kang Luo, Yi Quan, Sun Woo Lim, Yoo Jin Shin, Kyung Eun Lee, Hong Lim Kim, Eun Jeong Ko, Ju Hwan Kim, Sang J. Chung, Soo Kyung Bae, Byung Ha Chung, Chul Woo Yang
Korean J Intern Med. 2021;36(4):949-961. Published online January 12, 2021
Background/Aims: Coenzyme Q10 (CoQ10), is a promising antioxidant; however, low bioavailability owing to lipid-solubility is a limiting factor. We developed water-soluble CoQ10 (CoQ10-W) and compared its effects with conventional lipid-soluble CoQ10

The therapeutic efficacy of water-soluble coenzyme Q10 in an experimental model of tacrolimus-induced diabetes mellitus
Yi Quan, Kang Luo, Sheng Cui, Sun Woo Lim, Yoo Jin Shin, Eun Jeong Ko, Ju Hwan Kim, Sang J. Chung, Soo Kyung Bae, Byung Ha Chung, Chul Woo Yang
Korean J Intern Med. 2020;35(6):1443-1456. Published online April 14, 2020
Background/Aims: Coenzyme Q10 (CoQ10) has antioxidant effects and is commercially available and marketed extensively. However, due to its low bioavailability, its effects are still controversial. We developed a water-soluble CoQ10-based micelle formulation (CoQ10-W) ..

Assessment of nephrotoxicity of herbal medicine containing aristolochic acid in mice
Yi Quan, Long Jin, Kang Luo, Jian Jin, Sun Woo Lim, Yoo Jin Shin, Eun Jeong Ko, Byung Ha Chung, Chul Woo Yang
Korean J Intern Med. 2020;35(2):400-407. Published online November 21, 2019
Background/Aims: It is undetermined if herbal medicines (HM) containing aristolochic acid (AA)-containing have similar nephrotoxicity to AA itself.
Methods: We administered HM containing a high concentration of AA for 5 days (short-term study) or a low concentration of AA for 30 days (long-term stu..

Shen-Kang protects against tacrolimus-induced renal injury
Long Ye Zhang, Jian Jin, Kang Luo, Shang Guo Piao, Hai Lan Zheng, Ji Zhe Jin, Sun Woo Lim, Bum Soon Choi, Chul Woo Yang, Can Li
Korean J Intern Med. 2019;34(5):1078-1090. Published online February 12, 2018
Background/Aims: Evidence suggests that Shen-Kang (SK), a traditional Chinese herbal medicine, protects against various types of renal injury. In this study, we evaluated whether SK treatment confers renoprotection in a rat model of chronic tacrolimus (TAC) nephropathy.
Methods: Rats were treated d..
