The Zuo Jin Wan Formula increases chemosensitivity of human primary gastric cancer cells by AKT mediated mitochondrial translocation of cofilin-1

chinese Journal of Natural medicines 2019年第3期17卷 198-208页

作者： SUN Meng-Yao WANG Dan-Dan SUN Jian ZHAO Xiao-Hua CAI Si WU Qiu-Xue JIE Tao NI Zhen-Hua SUN Jian-Yue TANG Qing-Feng Department of Clinical Laboratory and Central Laboratory Putuo Hospital Shanghai University of Traditional Chinese Medicine Institute of Interdisciplinary Medical Sciences Shanghai University of Traditional Chinese Medicine Department of Clinical Laboratory Shuguang Hospital Shanghai University of Traditional Chinese Medicine Department of Pediatrics Putuo Hospital Shanghai University of Traditional Chinese Medicine

Resistance to cisplatin(DDP)-based chemotherapy is a major cause of treatment failure in human gastric cancer(GC). It is necessary to identify the drugs to re-sensitize GC cells to DDP. In our previous research, Zuo Jin Wan Formula(ZJW) has been proved could increase the mitochondrial apoptosis via cofilin-1 in a immortalized cell line, SGC-7901/DDP. Due to the immortalized cells may still difficult highly recapitulate the important molecular events in vivo, primary GC cells model derived from clinical patient was constructed in the present study to further evaluate the effect of ZJW and the underlying molecular mechanism. Immunofluorescent staining was used to indentify primary cultured human GC cells. Western blotting was carried out to detect the protein expression. Cell Counting Kit-8(CCK-8) was used to evaluate cell proliferation. Flow cytometry analysis was performed to assess cell apoptosis. ZJW inhibited proliferation and induced apoptosis in primary DDP-resistant GC cells. Notably, the apoptosis in GC cells was mediated by inducing cofilin-1 mitochondrial translocation, down-regulating Bcl-2 and up-regulating Bax expression. Surprisingly, the level of p-AKT protein was higher in DDP-resistant GC cells than that of the DDP-sensitive GC cells, and the activation of AKT could attenuate ZJW-induced sensitivity to DDP. These data revealed that ZJW can increase the chemosensitivity in DDP-resistant primary GC cells by inducing mitochondrial apoptosis and AKT inactivation. The combining chemotherapy with ZJW may be an effective therapeutic strategy for GC chemoresistance patients.

The expression of MAPK signaling pathways in conjunctivochalasis

International Journal of Ophthalmology(English edition) 2019年第11期12卷 1801-1806页

作者： Yuan-Ling Jia Xiao-Jing Liu Hang Wen Yue-Ping Zhan Min-Hong Xiang Department of Ophthalmology Putuo Hospital Shanghai University of Traditional Chinese Medicine

This study investigated the potential role of MAPK signaling pathways in conjunctivochalasis(CCH). Twenty loose conjunctival biopsy samples from 20 CCH and 15 conjunctival biopsy samples from 15 normal controls(CON) were collected. The conjunctival fibroblasts were cultured in vitro. Immunofluorescence, ELISA, Western blot and reverse transcription-polymerase chain reaction(RT-PCR) were used. Our results showed that the expression of p-ERK, p-JNK, and p-p38 in CCH conjunctiva was significantly higher than that in CON group. The expression of p38 MAPK, JNK, and ERK proteins in CCH fibroblasts was significantly higher than that in CON group. The total expression of MAPK m RNA in CCH fibroblasts was significantly higher than that in CON group. The activated forms of p38 MAPK, JNK, and ERK proteins and m RNAs might up-regulate the expression of MMPs in CCH loose conjunctival tissue and fibroblasts, causing the degradation of collagen fibers and elastic fibers and promoting the occurrence of CCH. Our results deepen the understanding of CCH pathological mechanism.

作者： Jing-Yun Gan Qing-Song Li Huan-Ming Zhou Wei Zhang Ling-Zhi Lian Zhang Yu Zhen-Yong Zhang Department of Ophthalmology Putuo Hospital Shanghai University of Traditional Chinese Medicine Department of Pathology Putuo Hospital Shanghai University of Traditional Chinese Medicine Department of Electron Microscopy Shanghai Medical College Fudan University

AIM： To explore a feasible method on the establishment of an animal model of conjunctivochalasis （CCH）. METHODS： Twelve clean-grade New Zealand white rabbits were divided into four groups （n=3/group）： the control group （one received no interventions, and the others underwent subconjunctival injection of sterile water）, the matrix metalloproteinases （MMPs） group （administered subconjunctival injection of MMP-3）, the aging group （administered subcutaneous injection of D-galactose）, the tumor necrosis factor-α （TNF-α） solution group （administered eye drops of TNF-α）. Anterior segment photography, conjunctival tissue light microscopy and transmission electron microscopy （TEM） were performed after 12wk. RESULTS： Among all groups, the MMPs group had the following changes： the looser connection between the inferior bulbar conjunctiva and sclera; the more disordered collagen fibers （Trichrome staining） and the broken elastic fibers （Aldehyde-fuchsin staining）; the focal necrosis of fibroblasts （TEM）. CONCLUSION： Administration of MMPs may be a feasible method for the establishment of an animal model of CCH.
