| 1 | Human mesenchymal stem cells derived from umbilical cord and bone marrow exert immunomodulatory effects in different mechanisms显示文摘BACKGROUND Mesenchymal stem cells(MSCs)are an attractive tool to treat graft-versus-host disease because of their unique immunoregulatory properties.Although human bone marrow-derived MSCs(BM-MSCs)were the most widely used MSCs in cell therapy until recently,MSCs derived from human umbilical cords(UC-MSCs)have gained popularity as cell therapy material for their ethical and noninvasive collection.AIM To investigate the difference in mechanisms of the immunosuppressive effects of UC-MSCs and BM-MSCs.METHODS To analyze soluble factors expressed by MSCs,such as indolamine 2,3-dioxygenase,cyclooxygenase-2,prostaglandin E2 and interleukin(IL)-6,inflammatory environments in vitro were reconstituted with combinations of interferon-gamma(IFN-γ),tumor necrosis factor alpha and IL-1βor with IFN-γalone.Activated T cells were cocultured with MSCs treated with indomethacin and/or anti-IL-10.To assess the ability of MSCs to inhibit T helper 17 cells and induce regulatory T cells,induced T helper 17 cells were cocultured with MSCs treated with indomethacin or anti-IL-10.Xenogeneic graft-versus-host disease was induced in NOG mice(NOD/Shi-scid/IL-2Rγnull)and UC-MSCs or BM-MSCs were treated as cell therapies.RESULTS Our data demonstrated that BM-MSCs and UC-MSCs shared similar phenotypic characteristics and immunomodulation abilities.BM-MSCs expressed more indolamine 2,3-dioxygenase after cytokine stimulation with different combinations of IFN-γ,tumor necrosis factor alpha-αand IL-1βor IFN-γalone.UC-MSCs expressed more prostaglandin E2,IL-6,programmed death-ligand 1 and 2 in the in vitro inflammatory environment.Cyclooxygenase-2 and IL-10 were key factors in the immunomodulatory mechanisms of both MSCs.In addition,UC-MSCs inhibited more T helper 17 cells and induced more regulatory T cells than BM-MSCs.UC-MSCs and BM-MSCs exhibited similar effects on attenuating graft-versus-host disease.CONCLUSION UC-MSCs and BM-MSCs exert similar immunosuppressive effects with different mechanisms involved.These findings suggest that UC-MSCs have distinct immunoregulatory functions and may substitute BM-MBSCs in the field of cell therapy. | Yunejin Song Jung-Yeon Lim Taekyu Lim Keon-Il Im Nayoun Kim Young-Sun Nam Young-Woo Jeon Jong Chul Shin Hyun Sun Ko In Yang Park Seok-Goo Cho | 2020 | World Journal of Stem Cells2020，12，9： | 4 |

| 3 | 来自一项艾日布林联合吉西他滨对比紫杉醇联合吉西他滨作为HER2阴性转移性乳腺癌的一线化疗的Ⅱ期、多中心、随机试验的包含神经病变相关量表的生活质量结果:韩国癌症研究组试验(KCSG BR13-11)显示文摘背景与目的一项比较艾日布林联合吉西他滨(eribulin plus gemcitabine,EG)或紫杉醇联合吉西他滨(paclitaxel plus gemcitabine,PG)作为转移性乳腺癌(metastatic breast cancer,MBC)患者一线化疗方案的II期临床试验发现,EG方案的神经毒性较低,但疗效与PG方案相似。在本研究中,我们分析了该临床实验中的癌症患者生命质量测评量表–紫杉烷(functional assessment of cancer therapy-taxane,FACT-Taxane)问卷评分以确定他们的生活质量(quality of life,QoL)。方法使用韩国版的FACT-Taxane问卷评估QoL。在评估基线之后,前12个疗程中每2个疗程评估1次QoL,之后每3个疗程评估1次QoL。使用线性混合模型评估EG组和PG组QoL的差异。结果在118例入组患者中,117例在基线时回复了FACT-Taxane问卷,PG组中有1例患者没有回复。EG组和PG组之间的基线QoL评分没有差异。在治疗期间,除了第11个疗程外,在第2–13个化疗疗程后,PG组紫杉烷亚量表评分显著高于EG组(均P<0.05)。神经病变特异性分析显示PG组患者的神经病症状比EG组患者更早出现且更严重(P<0.001)。结论在我们的QoL分析中,与PG方案相比,EG方案延迟并减少神经病变的发生。因此,艾日布林是MBC一线化疗药物紫杉醇的合理替代品。 | Ji‑Yeon Kim Seri Park Seock‑Ah Im Sung‑Bae Kim Joohyuk Sohn Keun Seok Lee Yee Soo Chae Ki Hyeong Lee Jee Hyun Kim Young‑Hyuck Im Tae‑Yong Kim Kyung‑Hun Lee Jin‑Hee Ahn Gun Min Kim In Hae Park Soo Jung Lee Hye Sook Han Se Hyun Kim Kyung Hae Jung Yeon Hee Park Korean Cancer Study Group | 2019 | 癌症2019，38，8： | 2 |
| 4 | Inhibition of BET selectively eliminates undifferentiated pluripotent stem cells显示文摘Embryonic stem cells(ESCs) maintain their cellular identity through the systematic regulation of master transcription factors and chromatin remodeling complexes. Recent work has shown that the unusually large-scale enhancers—namely super-enhancers(SEs), on which BRD4, a member of the bromodomain and extraterminal domain(BET) family is highly enriched—could regulate pluripotency-related transcription factors. Moreover, inhibition of BRD4 binding on SEs has been shown to induce the differentiation of ESCs. However, the underlying mechanism of BRD4 inhibition-mediated stem cell differentiation remains elusive. Here we show that both mouse and human ESCs lose their capacity for self-renewal upon treatment with JQ1, a selective inhibitor of BET family including BRD4, with rapid suppression of pluripotency-associated genes. Notably, a high concentration of JQ1 could selectively eliminate ESCs via apoptosis, without affecting the functionality of differentiated somatic cells from ESCs, suggesting that inhibition of BET may have a beneficial effect on the development of pluripotent stem cell-based cell therapy. | Jung Hyun Im Seon In Hwang Jong-Wan Kim soon-Jung Park Kyu-ree Kang Jueng Soo You Kee Pyo Kim Sung-Hwan Moon Hyuk-Jin Cha Hyung-Min Chung Hans R.

| 9 | Direct Synthesis of Molybdenum Phosphide Nanorods on Silicon Using Graphene at the Heterointerface for Efficient Photoelectrochemical Water Reduction显示文摘Transition metal phosphides(TMPs)and transition metal dichalcogenides(TMDs)have been widely investigated as photoelectrochemical(PEC)catalysts for hydrogen evolution reaction(HER).Using high-temperature processes to get crystallized compounds with large-area uniformity,it is still challenging to directly synthesize these catalysts on silicon photocathodes due to chemical incompatibility at the heterointerface.Here,a graphene interlayer is applied between p-Si and MoP nanorods to enable fully engineered interfaces without forming a metallic secondary compound that absorbs a parasitic light and provides an inefficient electron path for hydrogen evolution.Furthermore,the graphene facilitates the photogenerated electrons to rapidly transfer by creating Mo-O-C covalent bondings and energetically favorable band bending.With a bridging role of graphene,numerous active sites and anti-reflectance of MoP nanorods lead to significantly improved PEC-HER performance with a high photocurrent density of 21.8 mA cm−2 at 0 V versus RHE and high stability.Besides,low dependence on pH and temperature is observed with MoP nanorods incorporated photocathodes,which is desirable for practical use as a part of PEC cells.These results indicate that the direct synthesis of TMPs and TMDs enabled by graphene interlayer is a new promising way to fabricate Si-based photocathodes with high-quality interfaces and superior HER performance. | Sang Eon Jun Seokhoon Choi Shinyoung Choi Tae Hyung Lee Changyeon Kim Jin Wook Yang Woon‑Oh Choe In‑Hyuk Im Cheol‑Joo Kim Ho Won Jang | 2021 | Nano-Micro Letters2021，13，5： | 1 |

| 16 | Quality of life outcomes including neuropathy-associated scale from a phase II,multicenter,randomized trial of eribulin plus gemcitabine versus paclitaxel plus gemcitabine as first-line chemotherapy for HER2-negative metastatic breast cancer:Korean Cancer Study Group Trial(KCSG BR13-11)显示文摘Background: A phase II clinical trial of the comparison between eribulin plus gemcitabine (EG) and paclitaxel plus gemcitabine (PG) as first-line chemotherapy for patients with metastatic breast cancer (MBC) found that the EG regimen was less neurotoxic, but was similar in efficacy to the PG regimen. In the present study, we analyzed functional assessment of cancer therapy-taxane (FACT-Taxane) questionnaires from patients in this clinical trial to determine their quality of life (QoL). Methods: QoL was assessed using the Korean version of the FACT-Taxane questionnaires. After baseline assessment, QoL was assessed every 2 cycles for 12 cycles and every 3 cycles thereafter. The linear mixed model was used to evaluate the difference in QoL between the EG and PG arms. Results: Of the 118 enrolled patients, 117 responded to the FACT-Taxane questionnaires at baseline, 1 in the PG arm did not. Baseline QoL scores were not different between the EG and PG arms. During treatment, taxane subscale scores were significantly higher in the PG arm than in the EG arm after 2-13 cycles of chemotherapy (all P < 0.05), except for the 11th cycle. Neuropathy-specific analysis showed that patients in the PG arm had earlier and more severe neuropathic symptoms than those in the EG arm (P < 0.001). Conclusions: In our QoL analysis, the EG regimen delayed and decreased neuropathy as compared with the PG regimen. Therefore, eribulin would be a reasonable substitute for paclitaxel as first-line chemotherapy for MBC. | Ji-Yeon Kim Seri Park Seock-Ah Im Sung-Bae Kim Joohyuk Sohn Keun Seok Lee Yee Soo Chae Ki Hyeong Lee Jee Hyun Kim Young-Hyuck Im Tae-Yong Kim Kyung-Hun Lee Jin-Hee Ahn Gun Min Kim In Hae Park Soo Jung Lee Hye Sook Han Se Hyun Kim Kyung Hae Jung Yeon Hee Park Korean Cancer Study Group | 2019 | Cancer Communications2019，39，1： | 1 |
