1Identification and expansion of cancer stem cells in tumor tissues and peripheral blood derived from gastric adenocarcinoma patients显示文摘胃的癌症是世界范围的第四很普通的癌症,与死亡的高率和低 5 年的幸存率。迄今为止,有为胃的癌症的有效治疗学的协议的缺乏。最近的研究建议癌症干细胞(CSC ) 为肿瘤开始,侵略,转移,和抵抗负责到 anticancer 治疗。因此,指向胃的 CSC 的治疗是吸引人的。然而,在人的胃的腺癌(GAC ) 的 CSC 没被描述。这里,我们从 GAC 病人在肿瘤纸巾和外部血识别 CSC。从肿瘤纸巾和病人的外部血被孤立的人的 GAC (GCSC ) 的 CSC 带了 CD44 和 CD54 表面标记,当注入了 immunodeficient 老鼠时,高度类似于原来的人的肿瘤的产生肿瘤,在 vitro 区分了进胃的上皮的房间,并且在 vivo 并且在 vitro 自我更新。我们的调查结果建议有效治疗学的协议必须指向 GCSC。从 GAC 病人的循环的 GCSC 的俘获也为为肿瘤转移潜在地负责的一张批评房间人口的鉴定显示出大潜力,并且为早诊断并且胃的癌症的纵的监视提供一个有效协议。Tie Chen Kun Yang Jianhua Yu Wentong Meng Dandan Yuan Feng Bi Fang Liu Jie Liu Bing Dai Xinzu Chen Fang Wang Fan Zeng Hong Xu Jiankun Hu Xianming Mo 2012Cell Research2012,22,1:50
2Changed clinical aspects of primary liver cancer in China during the past 30 years显示文摘BACKGROUND: Primary liver cancer (PLC) is one of the most frequently seen tumors in China. Thirty years ago, patients with PLC were often detected at relatively late stage, with a palpable mass or marked clinical symptoms and poor prognosis. In the past 30 years, the diagnosis and treatment of PLC have been greatly improved with better prognosis. METHODS: In order to study the changes of PLC during the 30 years, the clinical data of 3250 patients with PLC from 10 medical institutions of China were collected, ana- lyzed , and compared with those of 3254 PLC patients be- fore the 30 years. RESULTS: In the 3250 patients aged 1-80 years, with an average age of 49.1 years, the male to female ratio (2.3:1) was lower than that before the 30 years. 73.5% of the 3250 patients sought medical advice within 3 months after the onset of the disease in contrast to 63.8% before the 30 years. Compared with those patients before the 30 years the symptoms and signs were alleviated generally. The HBsAg positive rate was 81.0%, but the HCV-Ab positive rate was 13.2%. The AFP level in 75% of patients was elevated, but in the remaining 25% was normal. 1912 patients (58.8%) were confirmed pathologically. Among them 1755 patients (91.8%) had hepatocellular carcinoma. The overall resec- tion rate was 46.3%. Those who had early, middle, late stage carcinoma accounted for 29.9%, 51.5%, and 18.6%respectively in contrast to 0.4%, 47.0%, and 52.6% repor- ted before the 30 years. The 1-, 3-, 5-year survival rates of the patients were 66.1%, 39.7%, and 32.5% respectively, whereas 93.5%, 70.1%, and 59.1% for the early stage pa- tients, and 65.3%, 30.5%, and 23.5% for the middle stage patients. The half and 1-year survival rates of the late stage patients were 52.5%, and 14.7%, respectively. CONCLUSION: Comparison with the clinical data before and after the 30 years show that PLC can be diagnosed ear- ly. More PLC patients tend to undergo resection while re- ceiving a better conservative treatment, which ensures a prognosis.Bing-Hui Yang, Jing-Lin Xia, Li-Wen Huang, Zhao-You Tang, Ming-Shan Chen, Jin-Qing Li, An-Min Liang, Qin-Guo Mo, Hui-Shan Lu, Chao-Liu Dai, Lu-Nan Yan, Zhi-Jian Yu, Rong-Sheng Rao, Le-Qun Li, Zhi-Xiong Su, Zhuang-Wei Fang Shanghai, China Liver Cancer Institute & Zhongshan Hospital, Fudan University, Shanghai 200032, China Tumor Hospital, Zhongshan University, Guangzhou 510000, China Tumor Hospital, Guangxi Medical Universi- ty, Nanning 530000, China Xiehe Hospital, Fujian Medical University, Fuzhou 350000, China Second Hos- pital, Chinese Medical University, Shenyang 110000, China Huaxi Hospital, Sichuan University, Chengdu 610041, China Hospital Affiliated to Nantong Medical University, Nantong 226000 , China Second Hospital, Jiangxi Medical University, Nanchang 330000 , China First Hospital Affiliated to Guangxi Medical University, Nanning 530000 , China People’s Hospital of Hainan Province, Haikou 570000, China 2004Hepatobiliary & Pancreatic Diseases International2004,3,2:20

4Responses of the Toll-like receptor and melanoma differentiation-associated protein 5 signaling pathways to avian infectious bronchitis virus infection in chicks显示文摘Avian infectious bronchitis virus(IBV) is a Gammacoronavirus in the family Coronaviridae and causes highly contagious respiratory disease in chickens. Innate immunity plays significant roles in host defense against IBV. Here, we explored the interaction between IBV and the host innate immune system. Severe histopathological lesions were observed in the tracheal mucosa at 3–5days post inoculation(dpi) and in the kidney at 8 dpi, with heavy viral loads at 1–11 and 1–28 dpi,respectively. The expression of m RNAs encoding Toll-like receptor(TLR) 3 and TLR7 were upregulated at 3–8 dpi, and that of TIR-domain-containing adapter-inducing interferon(IFN) β(TRIF) was upregulated at 21 dpi in the trachea and kidney. Myeloid differentiation primary response protein 88(My D88) was upregulated in the trachea during early infection. Tumor necrosis factor receptor-associated factor(TRAF) 3 and TRAF6 were upregulated expression in both tissues.Moreover, melanoma differentiation-associated protein 5(MDA5), laboratory of genetics and physiology 2(LGP2), stimulator of IFN genes(STING), and mitochondrial antiviral signaling protein(MAVS), as well as TANK binding kinase 1(TBK1), inhibitor of kappa B kinase(IKK) ?, IKKα, IKKβ,IFN regulatory factor(IRF) 7, nuclear factor of kappa B(NF-κB), IFN-α, IFN-β, various interleukins(ILs), and macrophage inflammatory protein-1β(MIP-1β) were significantly upregulated in the trachea and downregulated in the kidney. These results suggested that the TLR and MDA5 signaling pathways and innate immune cytokine were induced after IBV infection. Additionally,consistent responses to IBV infection were observed during early infection, with differential and complicated responses in the kidney.Yining He Zhiwen Xie Jinglong Dai Yanjie Cao Jinlian Hou Yansheng Zheng Tianchao Wei Meilan Mo Ping Wei 2016Virologica Sinica2016,31,1:14

6Electroacupuncture-induced neuroprotection against focal cerebral ischemia in the rat is mediated by adenosine A1 receptors显示文摘The activation of adenosine A1 receptors is important for protecting against ischemic brain injury and pretreatment with electroacupuncture has been shown to mitigate ischemic brain insult. The aim of this study was to test whether the adenosine A1 receptor mediates electroacupuncture pretreatment-induced neuroprotection against ischemic brain injury. We first performed 30 minutes of electroacupuncture pretreatment at the Baihui acupoint(GV20), delivered with a current of 1 mA, a frequency of 2/15 Hz, and a depth of 1 mm. High-performance liquid chromatography found that adenosine triphosphate and adenosine levels peaked in the cerebral cortex at 15 minutes and 120 minutes after electroacupuncture pretreatment, respectively. We further examined the effect of 15 or 120 minutes electroacupuncture treatment on ischemic brain injury in a rat middle cerebral artery-occlusion model. We found that at 24 hours reperfusion,120 minutes after electroacupuncture pretreatment, but not for 15 minutes, significantly reduced behavioral deficits and infarct volumes. Last, we demonstrated that the protective effect gained by 120 minutes after electroacupuncture treatment before ischemic injury was abolished by pretreatment with the A1-receptor antagonist 8-cyclopentyl-1,3-dipropylxanthine(1 mg/kg, intraperitoneally). Our results suggest that pretreatment with electroacupuncture at the Baihui acupoint elicits protection against transient cerebral ischemia via action at adenosine A1 receptors.Qin-xue Dai Wu-jun Geng Xiu-xiu Zhuang Hong-fa Wang Yun-chang Mo He Xin Jiang-fan Chen Jun-lu Wang 2017Neural Regeneration Research2017,12,2:9

8Polar organic tracers in PM_(2.5) aerosols from an inland background area in Southwest China: Correlations between secondary organic aerosol tracers and source apportionment显示文摘PM_(2.5) aerosol samples were collected over 12 hr and 24 hr intervals in an inland background area, Gongga Mountain National Nature Reserve(hereafter shortened to Gongga), during the summer of 2011. Polar organic tracers, inorganic ions and meteorological data were measured. The purpose of this work was to investigate the variation patterns, formation and sources of the secondary organic aerosol tracers in the studied atmosphere. The average concentrations of isoprene oxidation products, α-pinene oxidation products, β-caryophyllinic acid, sugars, sugar alcohols and anhydrosugars were 88.6 ± 106.1, 3.6 ± 5.7,0.13 ± 0.30, 13.6 ± 13.1, 31.9 ± 31.4 and 14.8 ± 10.7 ng/m3 respectively in all aerosol samples.The aged α-pinene second organic aerosol(SOA) tracers(i.e., 3-hydroxyglutraric acid(3 HGA), 3-hydroxy-2,2-dimethylglutaric acid(HDMGA), 3-acetylpentandioic acid(APDA) and 3-methyl-1,2,3-butanetricarboxylic acid(MBTCA)) correlated significantly with each other in the 24 hr PM2.5 aerosol samples, indicating that OH· is the major factor controlling the formation of these α-pinene SOA tracers. Using the positive matrix factorization(PMF) model and the tracer-based source apportionment method, we calculated that isoprene oxidation products, α-pinene oxidation products, sesquiterpene oxidation products, biomass burning, fungi spores and anthropogenic SOA accounted for 21.9% ± 5.5%, 8.4% ± 2.1%, 3.0% ± 0.7%, 5.2% ± 5.3%, 5.0% ± 6.2% and 31.4% ± 7.8% of organic carbon respectively during the sampling period.Li Li Wei Lai Jinguo Pu Hengqin Mo Dongjue Dai Guilin Wu Shihuai Deng 2018Journal of Environmental Sciences2018,30,7:6
9A 3D-Bioprinted dual growth factor-releasing intervertebral disc scaffold induces nucleus pulposus and annulus fibrosus reconstruction显示文摘Regeneration of Intervertebral disc(IVD)is a scientific challenge because of the complex structure and composition of tissue,as well as the difficulty in achieving bionic function.Here,an anatomically correct IVD scaffold composed of biomaterials,cells,and growth factors were fabricated via three-dimensional(3D)bioprinting technology.Connective tissue growth factor(CTGF)and transforming growth factor-β3(TGF-β3)were loaded onto polydopamine nanoparticles,which were mixed with bone marrow mesenchymal stem cells(BMSCs)for regenerating and simulating the structure and function of the nucleus pulposus and annular fibrosus.In vitro experiments confirmed that CTGF and TGF-β3 could be released from the IVD scaffold in a spatially controlled manner,and induced the corresponding BMSCs to differentiate into nucleus pulposus like cells and annulus fibrosus like cells.Next,the fabricated IVD scaffold was implanted into the dorsum subcutaneous of nude mice.The reconstructed IVD exhibited a zone-specific matrix that displayed the corresponding histological and immunological phenotypes:primarily type II collagen and glycosaminoglycan in the core zone,and type I collagen in the surrounding zone.The testing results demonstrated that it exhibited good biomechanical function of the reconstructed IVD.The results presented herein reveal the clinical application potential of the dual growth factors-releasing IVD scaffold fabricated via 3D bioprinting.However,the evaluation in large mammal animal models needs to be further studied.Binbin Sun Meifei Lian Yu Han Xiumei Mo Wenbo Jiang Zhiguang Qiao Kerong Dai 2021Bioactive Materials2021,6,1:5

11Silencing miRNA-324-3p protects against cerebral ischemic injury via regulation of the GATA2/A1R axis显示文摘Previous studies have suggested that miR-324-3p is related to the pathophysiology of cerebral ischemia,but the mechanism underlying this relationship is unclea r.In this study,we found that miR-324-3p expression was decreased in patients with acute ischemic stroke and in in vitro and in vivo models of ischemic stro ke.miR-324-3p agomir potentiated ischemic brain damage in rats subjected to middle cerebral artery occlusion,as indicated by increased infarct volumes and cell apoptosis rates and greater neurological deficits.In a PC12 cell oxygen-glucose deprivation/reoxygenation model,a miR-324-3 p mimic decreased cell viability and expression of the anti-apoptotic protein BCL2 and increased expression of the pro-apoptotic protein BAX and rates of cell apoptosis,whereas treatment with a miR-324-3p inhibitor had the opposite effects.Silencing miR-324-3p increased adenosine A1 receptor(A1R)expression thro ugh regulation of GATA binding protein 2(GATA2).These findings suggest that silencing miR-324-3p reduces ischemic brain damage via the GATA2/A1R axis.An-Qi Zhang Lu Wang Yi-Xiu Wang Shan-Shan Hong Yu-Shan Zhong Ru-Yi Yu Xin-Lu Wu Bing-Bing Zhou Qi-Min Yu Hai-Feng Fu Shuang-Dong Chen Yun-Chang Mo Qin-Xue Dai Jun-Lu Wang 2022Neural Regeneration Research2022,17,11:3
12Better performance of germination in hyperosmotic solutions in conspecific weedy rice than cultivated rice显示文摘Weeds and crops that grow together often confront similar types of environmental stress, especially drought stress. Weedy rice (Oryza sativa f. spontanea) and cultivated rice (O. sativa L.) provide a unique pair consisting of a weed and a conspecific model crop that can be used to study the drought tolerance of plants across a large distributional range. The investigation on weedy rice’s damage to paddy fields showed that it was more serious in dry direct seeding than water direct seeding. Compared with water direct seeding, the seeds of cultivated rice and weedy rice in dry direct seeding will absorb water and germinate under the condition of insufficient soil moisture. Our hypothesis is that weedy rice seeds have evolved stronger germination ability than coexisting cultivated rice under water stress, so that they can obtain more growth space in the early stage in dry direct seeding and thus obtain higher fitness. Seeds of weedy rice populations and coexisting rice cultivars were collected from 61 sites across China and were germinated with 20% polyethylene glycol‐6000 to simulate drought stress. Two drought response indices, which assessed germination rate and germination index, plus one germination stress tolerance index, indicated significantly greater drought tolerance in weedy rice populations than in coexisting rice cultivars (P < 0.01). Drought tolerance for the three indexes were indica weedy rice > indica rice cultivars, japonica weedy rice > japonica rice cultivars, and indica weedy rice > japonica rice cultivars. These results indicate that weedy rice populations show stronger drought stress tolerance than coexisting rice cultivars at various sites, specifically during the seed germination period. Furthermore, Pearson’s correlation found that drought response of weedy rice populations and coexisting rice cultivars were significantly different with these environmental factors: latitude, altitude, annual mean precipitation, mean annual temperature, mean precipitation in the sowing month, mean temperature in the sowing month, and sowing methods. Weedy rice shows different patterns of drought tolerance variation across geographical (latitude and altitude) and environmental (precipitation) gradients compared to coexisting rice cultivars. This study suggests that weedy rice might have evolved new drought tolerance and could provide a useful source of genetic resources for improving drought tolerance of crop cultivars and breeding direct seeded cultivars to reduce the usage of seeds in direct seeding.Yuan Wang Shu-Da Mo Meng-Yao Kong Jing Chao Xiao-Feng Chen Jin-Ling Yang Yu-Jiang Yan Zhi-Hua Shi Sheng Qiang Xiao-Ling Song Wei-Min Dai 2019Journal of Systematics and Evolution2019,57,5:2
13Evolutionary biogeography on Ophiocordyceps sinensis:An indicator of molecular phylogeny to geochronological and ecological exchanges显示文摘The fungus Ophiocordyceps sinensis is endemic to the vast region of the Qinghai-Tibetan plateau(QTP).The unique and complex geographical environmental conditions have led to the 'sky island' distribution structure of O.sinensis.Due to limited and unbalanced sample collections,the previous data on O.sinensis regarding its genetic diversity and spatial structure have been deemed insufficient.In this study,we analyzed the diversity and phylogeographic structures of O.sinensis using internally transcribed spacer region(ITS) and 5-locus datasets by a large-scale sampling.A total of 111 haplotypes of ITS sequences were identified from 948 samples data of the fungus O.sinensis,with representing high genetic diversity,and 8 phylogenetic clades were recognized in O.sinensis.Both the southeastern Tibet and the northwestern Yunnan were the centers of genetic diversity and genetic differentiation of the fungus,and they were inferred as the glacial refugia in the Quaternary.Three distribution patterns were identified to correspond to the 8 clades,including but not limited to the coexistence of widely and specific local distributive structures.It also revealed that the differentiation pattern of O.sinensis did not fit for the isolation-by-distance model.The differentiation into the 8 clades occurred between 1.56 Myr and6.62 Myr.The ancestor of O.sinensis most likely originated in the late Miocene(6.62 Myr) in the northwestern Yunnan,and the Scene A-C of the Qinghai-Tibetan movements may have played an important role in the differentiation of O.sinensis during the late Miocene-Pliocene periods.Our current results provide a much clearer and detailed understanding of the genetic diversity and geographical spatial distribution of the endemic alpine fungus O.sinensis.It also revealed that the geochronology resulting from paleogeology could be cross-examined with biomolecular clock at a finer scale.Yongdong Dai Changkui Wu Feng Yuan Yuanbing Wang Luodong Huang Zihong Chen Wenbo Zeng Yao Wang Zhuliang Yang Pusheng Zeng Paul Lemetti Xuanxue Mo Hong Yu 2020Geoscience Frontiers2020,11,3:2
14Angioplasty with Stent for Symptomatic Intracranial Stenosis Trial I (ASSIT-Ⅰ) Study显示文摘Background and Purpose Annual stroke rates might be as high as 10% to 24% in patients with symptomatic intracranial stenosis on best medical therapy. Angioplasty with stent for symptomatic intracranial stenosis trial Ⅰ (ASSIST-Ⅰ) was a prospective and nonrandomized feasibility and safety study to evaluate the APOLLO Stent System for treatment of symptomatic intracranial artery stenosis, and prepare for ASSIST Ⅱ-a prospective, multicenter,and randomized controlled-study. The APOLLO stent delivery system (MicroPort Medical [Shanghai] Limited Co.), specifically designed for intracranial artery stenosis, consists of a stent and a balloon and a rapid-exchange delivery catheter. The stent is made of 316L stainless steel, with diameters of 2.0 to 4.0 mm and length of 8 mm or 13 mm. Only two links connect the rings of 1 mm in length, rendering the stent a good flexibility enough to navigate tortuous intracranial vessels. The nominated pressure of the stent is designed at 6 atm to reduce the risk of occlusion to side branches and perforators and rupture and dissection of target vessel. The crimping technique is applied in this system, insuring a compact ability of stent so wonderful that the struts of stent do not lift when the stent negotiates a turn, which lessen the likelihood of vessel wall injury and stent migrating. Materials and methods Thirty-four patients with 35 symptomatic intracranial stenoses of ≥50%, which resulted in transient ischemic attacks (TIAs [23 lesions /22 patients]) and minor stroke (7 lesions/7 patents), and both TIAs and stroke (5 lesions/ 5 patients), and with 1 asymptomatic severe stenosis, were enrolled in ASSIST-Ⅰ from December 10, 2003 to August 12, 2004. Their age was 54.3 years±SD of 9.49, three patients were male, and all had ≥1 risk factors of atherosclerosis. Patients received the evaluation of National Institutes of Health Stroke Scale (NIHSS), modified Rankin scale (mRS )and Barthel idex (BI) before and one-, three-, six-, and 12-month after the procedure. Results Stent success, defined as stent-assisted angioplasty successfully, resulting in ≤20% residual stenosis, was obtained in 35 lesions ( 97.2%, 35/36) and 33 patients ( 97.1%, 33/34). The stenosis rate of pre- and post -procedure was 80.5%± SD of 12.65 and 7.4%±SD 15.74, respectively. The Procedure-related complications were 8.3% for lesion (3/36) and 8.8% for patient (3/34), included 1 acute thrombosis, which obtained complete patency by means of intrathrombus thombolysis at once without sequelae, and 2 ischemic perforator strokes (1 irreversible stroke and 1 reversible). The disable stroke, defined as one that led to mRS score of ≥2, 30 days after the stroke, occurred in one patient ( 2.9%, 1/34; mRS of 2). Procedure success, defined as stent success without disable stroke or death at discharge by means of the endovascular therapy, was achieved in 33 lesions ( 91.7%, 33/36) and in 31 patients ( 91.2%, 31/34). Treatment success, defined as stent success without disable stroke and death at the 30th day, by means of the endovascular and medical therapy, was obtained in 34 lesions ( 94.4%, 34/36) and 32 patients ( 94.1%, 32/34). Clinical Follow-up, median 170 days (ranged from 30 days to 273 days; ≥1 month, n=34; ≥3 months, n=23; ≥6 months, n=13), was performed in 34 patients. There were no ischemic neurological events and death occurred. Cumulated disable stroke occurred in 1 patient ( 2.9%, 1/34). NIHSS was 1.09±SD of 1.694 and 0.47±SD of 1.051, before procedure and at the 30th day (n=34), respectively, and 0.57±SD of 0.992 at 3 months (n=23), 0.15±SD of 0.376 at 6 months (n=13), respectively; mRS was 0.65±SD of 0.812 and 0.47±SD of 0.563, before procedure and at 30 days, respectively, and 0.61±SD of 0.583 at 3 months, 0.38±SD of 0.506 at 6 months, respectively; and BI was 97.54±SD of 5.918 and 99.26±SD of 2.179, before procedure and at 30 days, respectively, and 99.35±SD of 2.288 at 3 months, 100.00±SDWei-Jian Jiang, MD Min Jin, MD Bin Du, MD Yong-Jun Wang, MD Xiao-Tong Xu, MD Qing-He Wang, MD Ning Ma, MD Long-Yi Wang, MO Jian-Ping Dai, MD From the Neurovascular Angioplasty Team, Department of Neurology and Neuroradiology, Beijing Tiantan Hospital, Capital University of Medical Sciences, Beijing, China.

15A multistep attachment process:Transformation of titanate nanotubes into nanoribbons显示文摘The mechanism of the conversion of titanate nanotubes into nanoribbons is of considerable interest.The details of the transformation processes involved when nanoribbons are produced from a P25 TiO 2 powder precursor by alkaline hydrothermal treatment have been investigated systematically by transmission electron microscopy.A multistep attachment model is proposed for the growth at the early stage of coarsening.The treatment duration has a strong effect on the change in product morphology from hollow nanotubes into nanoribbons,since the nanotubes cannot retain their morphology in the strong alkaline solution for extended periods of time.Most of the nanotubes were etched and dissolved,providing the nutrients for subsequent nanoribbon growth.Some stable nanotubes grew spirally internally to form nanowires or became connected together to form rafts which acted as the grains for nanoribbon growth.With increasing hydrothermal time,a large number of nanotubes and other fragments became attached to the grains which began to grow larger and eventually formed the nanoribbons,in a process in which the stepped faces and kinked faces became fused and were eliminated while the flat faces were retained in the nanoribbon morphology.SHENG Jiang HU LinHua MO Li'E LI WenXin TIAN HuaJun DAI SongYuan 2012Science China Chemistry2012,55,3:2

19GLUT3 induced by AMPK/CREB1 axis is key for withstanding energy stress and augments the efficacy of current colorectal cancer therapies显示文摘Cancer cells are usually characterized by hyperactive glucose metabolism,which can often lead to glucose scarcity;thus,alternative pathways to rewire cancer metabolism are required.Here,we demonstrated that GLUT3 was highly expressed in colorectal cancer(CRC)and negatively linked to CRC patient outcomes,whereas GLUT1 was not associated with CRC prognosis.Under glucoselimiting conditions,GLUT3 expedited CRC cell growth by accelerating glucose input and fuelling nucleotide synthesis.Notably,GLUT3 had a greater impact on cell growth than GLUT1 under glucose-limiting stress.Mechanistically,low-glucose stress dramatically upregulated GLUT3 via the AMPK/CREB1 pathway.Furthermore,high GLUT3 expression remarkably increased the sensitivity of CRC cells to treatment with vitamin C and vitamin C-containing regimens.Together,the results of this study highlight the importance of the AMPK/CREB1/GLUT3 pathway for CRC cells to withstand glucose-limiting stress and underscore the therapeutic potential of vitamin C in CRC with high GLUT3 expression.Weixing Dai Ye Xu Shaobo Mo Qingguo Li Jun Yu Renjie Wang Yanlei Ma Yan Ni Wenqiang Xiang Lingyu Han Long Zhang Sanjun Cai Jun Qin Wen-Lian Chen Wei Jia Guoxiang Cai 2020Signal Transduction and Targeted Therapy2020,5,1:1
