| 1 | Retrospective analysis of extra-gastrointestinal stromal tumors显示文摘AIM:To investigate the clinicopathologic features of patients with extra-gastrointestinal stromal tumors(EGISTs)in South Korea.METHODS:A total of 51 patients with an EGIST were identified.The clinicopathologic features,including sex,age,location,tumor size,histology,mitotic rate,immunohistochemical features,genetic status and survival data,were analyzed.RESULTS:The median age was 55 years(range:29-80years),and male:female ratio was 1:1.04.The most common site was in the mesentery(n=15)followed by the retroperitoneum(n=13)and omentum(n=8).The median tumor size was 9.0 cm(range:2.6-30.0cm)and the median mitotic rate was 5.0/50HPF.(1/50-185/50).KIT was analyzed in 16,which revealed 10cases with wild-type KIT and 6 cases with an exon 11mutation.Among 51 patients,31 patients had undergone surgery,and 10 had unresectable disease and had taken palliative imatinib,which resulted in 22.7 mo of progression-free survival.Of the patients who had undergone surgery,18 did not take adjuvant imatinib,and 8 of these were categorized as'high risk'according to the risk criteria.However,the relapse-free survival was not different(P=0.157)between two groups.CONCLUSION:Because the biologic behaviors of GISTs differ according to the location of the tumor,a more stratified strategy is required for managing EGISTs including incorporation of molecular features. | Jun Ho Yi Byeong-Bae Park Jung Hun Kang In Gyu Hwang Dong Bok Shin Sun Jin Sym Hee Kyung Ahn Soon Il Lee Do Hyoung Lim Keon Woo Park Young-Woong Won Sung Hee Lim Se Hoon Park | 2015 | World Journal of Gastroenterology2015，21，6： | 9 |
| 2 | Memory-centric neuromorphic computing for unstructured data processing显示文摘The unstructured data such as visual information,natural language,and human behaviors opens up a wide array of opportunities in the field of artificial intelligence(Al).The memory-centric neuromorphic computing(MNC)has been proposed for the efficient processing of unstructured data,bypassing the von Neumann bottleneck of current computing architecture.The development of MNC would provide massively parallel processing of unstructured data,realizing the cognitive Al in edge and wearable systems.In this review,recent advances in memory-centric neuromorphic devices are discussed in terms of emerging nonvolatile memories,volatile switches,synaptic plasticity,neuronal models,and memristive neural network. | Sang Hyun Sung Tae Jin Kim Hera Shin Hoon Namkung Tae Hong Im Hee Seung Wang Keon Jae Lee | 2021 | Nano Research2021，14，9： | 3 |

| 4 | Snail acetylation by autophagy-derived acetyl-coenzyme A promotes invasion and metastasis of KRAS-LKB1 co-mutated lung cancer cells显示文摘Background: Autophagy is elevated in metastatic tumors and is often associatedwith active epithelial-to-mesenchymal transition (EMT). However, the extent towhich EMT is dependent on autophagy is largely unknown. This study aimed toidentify the mechanisms by which autophagy facilitates EMT.Methods: We employed a liquid chromatography-based metabolomic approachwith kirsten rat sarcoma viral oncogene (KRAS) and liver kinase B1 (LKB1)gene co-mutated (KL) cells that represent an autophagy/EMT-coactivatedinvasive lung cancer subtype for the identification of metabolites linked to autophagy-driven EMT activation. Molecular mechanisms of autophagy-drivenEMT activation were further investigated by quantitative real-time polymerasechain reaction (qRT-PCR), Western blotting analysis, immunoprecipitation,immunofluorescence staining, and metabolite assays. The effects of chemicaland genetic perturbations on autophagic flux were assessed by two orthogonalapproaches: microtubule-associated protein 1A/1B-light chain 3 (LC3) turnoveranalysis by Western blotting and monomeric red fluorescent protein-greenfluorescent protein (mRFP-GFP)-LC3 tandem fluorescent protein quenchingassay. Transcription factor EB (TFEB) activity was measured by coordinatedlysosomal expression and regulation (CLEAR) motif-driven luciferase reporterassay. Experimental metastasis (tail vein injection) mouse models were used toevaluate the impact of calcium/calmodulin-dependent protein kinase kinase 2(CAMKK2) or ATP citrate lyase (ACLY) inhibitors on lung metastasis using IVISluciferase imaging system.Results: We found that autophagy in KL cancer cells increased acetyl-coenzymeA (acetyl-CoA), which facilitated the acetylation and stabilization of theEMT-inducing transcription factor Snail. The autophagy/acetyl-CoA/acetylSnail axis was further validated in tumor tissues and in autophagy-activatedpancreatic cancer cells. TFEB acetylation in KL cancer cells sustained prometastatic autophagy in a mammalian target of rapamycin complex 1 (mTORC1)-independent manner. Pharmacological inhibition of this axis via CAMKK2inhibitors or ACLY inhibitors consistently reduced the metastatic capacity of KLcancer cells in vivo.Conclusions: This study demonstrates that autophagy-derived acetyl-CoA promotes Snail acetylation and thereby facilitates invasion and metastasis of KRASLKB1 co-mutated lung cancer cells and that inhibition of the autophagy/acetylCoA/acetyl-Snail axis using CAMKK2 or ACLY inhibitors could be a potentialtherapeutic strategy to suppress metastasis of KL lung cancer. | Jang Hee Han Yong Keon Kim Hakhyun Kim Jooyoung Lee Myung Joon Oh Sang Bum Kim Minjee Kim Kook Hwan Kim Hyun Ju Yoon Myung-Shik Lee John D.Minna Michael A.White Hyun Seok Kim | 2022 | Cancer Communications2022，42，8： | 2 |
| 5 | Weekly docetaxel and gemcitabine in previously treated metastatic esophageal squamous cell carcinoma显示文摘AIM: To assess the efficacy and safety of weekly docetaxel plus a fixed-dose rate(FDR) of gemcitabine in metastatic esophageal squamous cell carcinoma(SCC).METHODS: A multi-center, open-label, prospective phase Ⅱ study was designed.Thirty-three esophageal SCC patients with documented progression after fluoropyrimidine/platinum-based first-line chemotherapy were enrolled and treated with docetaxel 35 mg/m2 and gemcitabine 1000 mg/m2 iv at a FDR(10 mg/m2 per minute) on days 1 and 8.Treatment was repeatedevery twenty-one days until disease progression, unacceptable toxicity, or consent withdrawal.The primary endpoint was response rate(RR), and secondary endpoints were safety, progression-free survival(PFS) and overall survival(OS).RESULTS: Combination of weekly docetaxel and FDR gemcitabine was well tolerated: the most common treatment-related adverse events were anemia(97%), fatigue(64%) and neutropenia(55%).One patient with multiple lung and lymph node metastases died of respiratory failure after receiving four cycles of chemotherapy, and the possibility of drug-induced pneumonitis could not be completely excluded.Disease control(objective response plus stable disease) in the ITT population was achieved in 88% of patients, and the overall RR was 30%(95%CI: 15%-46%).The median PFS and OS were 4.0(95%CI: 3.4-4.6) and 8.8 mo(95%CI: 7.8-9.8 mo), respectively.CONCLUSION: A combination of weekly docetaxel and FDR gemcitabine showed promising antitumor activity and tolerability in previously treated, metastatic esophageal SCC. | Min-Young Lee Ki Sun Jung Hae Su Kim Ji Yun Lee Sung Hee Lim Moonjin Kim Hyun Ae Jung Sung Min Kim Jong Mu Sun Myung-Ju Ahn Jeeyun Lee Se Hoon Park Seong Yoon Yi In Gyu Hwang Sang-Cheol Lee Hee Kyung Ahn Do Hyoung Lim Soon Il Lee Keon Woo Park | 2015 | World Journal of Gastroenterology2015，21，14： | 2 |
| 6 | Chronic alcohol consumption potentiates the development of diabetes through pancreatic β-cell dysfunction显示文摘Chronic ethanol consumption is well established as a major risk factor for type-2 diabetes(T2D), which is evidenced by impaired glucose metabolism and insulin resistance. However, the relationships between alcoholconsumption and the development of T2 D remain controversial. In particular, the direct effects of ethanol consumption on proliferation of pancreatic β-cell and the exact mechanisms associated with ethanolmediated β-cell dysfunction and apoptosis remain elusive. Although alcoholism and alcohol consumption are prevalent and represent crucial public health problems worldwide, many people believe that low-tomoderate ethanol consumption may protect against T2 D and cardiovascular diseases. However, the J- or U-shaped curves obtained from cross-sectional and large prospective studies have not fully explained the relationship between alcohol consumption and T2 D. This review provides evidence for the harmful effects of chronic ethanol consumption on the progressive development of T2 D, particularly with respect to pancreatic β-cell mass and function in association with insulin synthesis and secretion. This review also discusses a conceptual framework for how ethanolproduced peroxynitrite contributes to pancreatic β-cell dysfunction and metabolic syndrome. | Ji Yeon Kim Dae Yeon Lee Yoo Jeong Lee Keon Jae Park Kyu Hee Kim Jae Woo Kim Won-Ho Kim | 2015 | World Journal of Biological Chemistry2015，6，1： | 2 |
