| 1 | The association between early-onset cardiac events caused by neoadjuvant or adjuvant chemotherapy in triple-negative breast cancer patients and some novel autophagy-related polymorphisms in their genomic DNA: a real-world study显示文摘Background:An increasing number of cancer patients die of cardiovascular diseases.The cardiotoxicity of chemo-therapy is particularly important in triple-negative breast cancer(TNBC)with limited therapeutic options.Cardiac autophagy is an important mechanism of cardiotoxicity.This research was aimed to investigate the cardiotoxicity of chemotherapy in TNBC,screen the susceptible population,and determine the relationship between cardiotoxicity and autophagy-related polymorphisms.Methods:From a total of 2450 stage I-III TNBC patients,147 met the inclusion criteria and finally recruited.Electro-cardiography(ECG)was performed before most chemotherapy cycles,and echocardiography(UCG)was performed according to clinical needs.All ECG and UCG records were re-interpreted by cardiologists at the National Center for Cardiovascular Disease,Fuwai Hospital.According to the National Center for Biotechnology Information and the Catalog of Somatic Mutations in Cancer database,we selected 25 single nucleotide polymorphisms(SNPs)related to autophagy and genotyped the 147 TNBC patients.Paired-sample T tests,Chi squared tests,and logistic regression models were employed for the analysis.Results:Only 46(31.3%)patients had normal ECG records after every chemotherapy cycle.Among the 16 patients who underwent UCG,2(12.5%)had a reversible decrease of left ventricular ejection fraction.The use of anthracyclines and excessive alcohol consumption were risk factors of ECG abnormalities.With the continuation of chemotherapy,heart rate gradually increased.Anthracyclines were associated with QRS duration abnormalities(P=0.043).After genotyping for 25 autophagy-related SNPs,we found that the G allele of autophagy-related 13(ATG13)rs10838611 was significantly associated with ECG abnormalities(odds ratio=2.258,95%confidence interval=1.318-3.869;P=0.003).Conclusion:ECG abnormalities caused by chemotherapy are common in the real world.Autophagy-related SNPs are associated with chemotherapy-induced cardiotoxicity,thereby providing new evidence for autophagy as a cause of chemotherapy-induced cardiac damage. | Binliang Liu Tao An Meiying Li Zongbi Yi Chunxiao Li Xiaoying Sun Xiuwen Guan Lixi Li Yanfeng Wang Yuhui Zhang Binghe Xu Fei Ma Yixin Zeng | 2018 | Cancer Communications2018，38，1： | 5 |
| 2 | Processes of dike-break induced flows:A combined experimental and numerical model study显示文摘Dike breaking is a disaster that could cause extensive damage. It could lead to flood flows outside the dike and induce water level fluctuations in the main channel. Numerical models are increasingly used to simulate flood flows due to dike-break, because direct observations from field surveys and physical models are rather limited. Existing knowledge concerning dam-break flows cannot be applied directly to dike-break flows because the effect of channel discharge cannot be neglected in the latter. In this study,physical experiments are done in a large laboratory flume to simulate the process of dike-break induced flood wave propagation in the floodplain and flow fluctuations in the main channel. The variations of water levels and velocities are measured and recorded using an array of pressure sensors and two acoustic Doppler velocimetry devices. A numerical model has been set up according to the experimental layout. The experiments have high repeatability and the numerical model predictions agree closely with the physical model data. The experimental results provide reliable information for improving the understanding of dike-break flow dynamics and for the verification of numerical models. | Jian Sun Lingwei Lu Binliang Lin Lu Liu | 2017 | International Journal of Sediment Research2017，32，4： | 4 |
| 3 | Antibody-drug conjugates in HER2-positive breast cancer显示文摘Antibody-drug conjugates(ADCs)combine the high specificity of monoclonal antibodies with the high anti-tumor activity of small molecular cytotoxic payloads.The anti-tumor activity of ADCs is mainly achieved by the direct blocking of the receptor by monoclonal antibodies,direct action and bystander effect of cytotoxic drugs,and antibody-dependent cell-mediated cytotoxicity and complement-dependent cytotoxicity.ADCs have been used in adjuvant therapy and rescue treatment of human epidermal receptor 2(HER2)-positive breast cancer,greatly improving the prognosis of breast cancer patients.Several ongoing clinical trials of ADC for breast cancer and other solid tumors proved the potential of ADCs will provide more promising treatment options for patients with malignant tumors.This review introduces the mechanism and latest clinical progress of ADC drugs approved for HER2-positive breast cancer to guide clinical practice and conduct research. | Lixi Li Di Zhang Binliang Liu Dan Lv Jingtong Zhai Xiuwen Guan Zongbi Yi Fei Ma | 2022 | Chinese Medical Journal2022，，3： | 2 |
| 4 | The molecular tumor burden index as a response evaluation criterion in breast cancer显示文摘Circulating tumor DNA(ctDNA)is a potential biomarker of prognosis and therapeutic response.We conducted this study to explore the role of the molecular tumor burden index(mTBI)in ctDNA as a therapeutic response and prognostic biomarker in a larger cohort prospective phase III randomized multicenter study.We collected 291 plasma samples from 125 metastatic breast cancer patients from the CAMELLIA study(NCT01917279).Target-capture deep sequencing of 1021 genes was performed to detect somatic variants in ctDNA from the plasma samples.The pretreatment mTBI value was correlated with tumor burden(P=0.025).Patients with high-level pretreatment mTBI had shorter overall survival than patients with low-level pretreatment mTBI,and the median overall survival was 40.9 months and 68.4 months,respectively(P=0.011).Patients with mTBI decrease to less than 0.02%at the first tumor evaluation had longer progression-free survival and overall survival(P<0.001 and P=0.007,respectively).The mTBI has good sensitivity to identify complete response/partial response and progressive disease based on computed tomography scans(88.5%and 87.5%,respectively).The patients classified as molecular responders had longer progression-free survival and overall survival than the nonmolecular responders in the overall cohort(P<0.001 and P=0.036,respectively),as well as in the cohort in which computed tomography scans were defined as representing stable disease(P=0.027 and P=0.015,respectively).The mTBI in ctDNA detected in liquid biopsies is a potential biomarker of therapeutic response and prognosis in patients with metastatic breast cancer. | Zongbi Yi Fei Ma Guohua Rong Binliang Liu Yanfang Guan Jin Li Xiaoying Sun Wenna Wang Xiuwen Guan Hongnan Mo Jiani Wang Haili Qian Binghe Xu | 2021 | Signal Transduction and Targeted Therapy2021，6，8： | 1 |
| 5 | Developmental Exposure to Bisphenol A Degrades Auditory Cortical Processing in Rats显示文摘Developmental exposure to bisphenol A(BPA),an endocrine-disrupting contaminant,impairs cognitive function in both animals and humans.However,whether BPA affects the development of primary sensory systems,which are the first to mature in the cortex,remains largely unclear.Using the rat as a model,we aimed to record the physiological and structural changes in the primary auditory cortex(A1)following lactational BPA exposure and their possible effects on behavioral outcomes.We found that BPA-exposed rats showed significant behavioral impairments when performing a sound temporal rate discrimination test.A significant alteration in spectral and temporal processing was also recorded in their A1,manifested as degraded frequency selectivity and diminished stimulus rate-following by neurons.These post-exposure effects were accompanied by changes in the density and maturity of dendritic spines in A1.Our findings demonstrated developmental impacts of BPA on auditory cortical processing and auditory-related discrimination,particularly in the temporal domain.Thus,the health implications for humans associated with early exposure to endocrine disruptors such as BPA merit more careful examination. | Binliang Tang Kailin Li Yuan Cheng Guimin Zhang Pengying An Yutian Sun Yue Fang Hui Liu Yang Shen Yifan Zhang Ye Shan E´tienne de Villers-Sidani Xiaoming Zhou | 2022 | Neuroscience Bulletin2022，38，11： | 0 |
| 6 | Clinical value of next-generation sequencing in guiding decisions regarding endocrine therapy for advanced HR-positive/HER-2-negative breast cancer显示文摘Objective: The mechanism of acquired gene mutation plays a major role in resistance to endocrine therapy in hormone receptor(HR)-positive advanced breast cancer. Circulating tumor DNA(ctDNA) has been allowed for the assessment of the genomic profiles of patients with advanced cancer. We performed this study to search for molecular markers of endocrine therapy efficacy and to explore the clinical value of ctDNA to guide precise endocrine therapy for HR-positive/human epidermal growth factor receptor-2(HER-2)-negative metastatic breast cancer patients.Methods: In this open-label, multicohort, prospective study, patients were assigned to four parallel cohorts and matched according to mutations identified in ctDNA: 1) activation of the phosphatidylinositol-3-kinase(PI3K)/AKT/mammalian target of rapamycin(mTOR) signaling pathway preferred mTOR inhibitor combined with endocrine therapy;2) estrogen receptor 1(ESR1) mutation preferred fulvestrant;3) HER-2 mutations preferred pyrotinib;and 4) no actionable mutations received treatment according to the clinical situation. In all cohorts, patients were divided into compliance group and violation group. The primary outcome measure was progression-free survival(PFS), and the secondary outcome measure was overall survival(OS).Results: In all cohorts, the combined median PFS was 4.9 months, and median PFS for the compliance and violation groups was 6.0 and 3.0 months, respectively [P=0.022, hazard ratio(HR)=0.57]. Multivariate Cox regression model showed the risk of disease progression was lower in compliance group than in violation group(P=0.023, HR=0.55). Among the patients with HER-2 mutations, the median PFS was 11.1 months in the compliance group and 2.2 months in the violation group(P=0.011, HR=0.20). There was no significant difference in the median PFS between patients who did and did not comply with the treatment protocol in patients with activation of the PI3K/AKT/mTOR or ESR1 mutation.Conclusions: The results suggest that ctDNA may help to guide the optimal endocrine therapy strategy for metastatic breast cancer patients and to achieve a better PFS. Next-generation sequencing(NGS) detection could aid in distinguishing patients with HER-2 mutation and developing new treatment strategies. | Dan Lyu Binliang Liu Bo Lan Xiaoying Sun Lixi Li Jingtong Zhai Haili Qian Fei Ma | 2022 | Chinese Journal of Cancer Research2022，34，4： | 0 |
| 7 | Overexpressed SIRT6 ameliorates doxorubicin-induced cardiotoxicity and potentiates the therapeutic efficacy through metabolic remodeling显示文摘Since the utilization of anthracyclines in cancer therapy, severe cardiotoxicity has become a major obstacle. The major challenge in treating cancer patients with anthracyclines is minimizing cardiotoxicity without compromising antitumor efficacy. Herein, histone deacetylase SIRT6 expression was reduced in plasma of patients treated with anthracyclines-based chemotherapy regimens. Furthermore,overexpression of SIRT6 alleviated doxorubicin-induced cytotoxicity in cardiomyocytes, and potentiated cytotoxicity of doxorubicin in multiple cancer cell lines. Moreover, SIRT6 overexpression ameliorated doxorubicin-induced cardiotoxicity and potentiated antitumor efficacy of doxorubicin in mice, suggesting that SIRT6 overexpression could be an adjunctive therapeutic strategy during doxorubicin treatment.Mechanistically, doxorubicin-impaired mitochondria led to decreased mitochondrial respiration and ATP production. And SIRT6 enhanced mitochondrial biogenesis and mitophagy by deacetylating and inhibiting Sgk1. Thus, SIRT6 overexpression coordinated metabolic remodeling from glycolysis to mitochondrial respiration during doxorubicin treatment, which was more conducive to cardiomyocyte metabolism, thus protecting cardiomyocytes but not cancer cells against doxorubicin-induced energy deficiency. In addition, ellagic acid, a natural compound that activates SIRT6, alleviated doxorubicininduced cardiotoxicity and enhanced doxorubicin-mediated tumor regression in tumor-bearing mice.These findings provide a preclinical rationale for preventing cardiotoxicity by activating SIRT6 in cancer patients undergoing chemotherapy, but also advancing the understanding of the crucial role of SIRT6 in mitochondrial homeostasis. | Kezheng Peng Chenye Zeng Yuqi Gao Binliang Liu Liyuan Li Kang Xu Yuemiao Yin Ying Qiu Mingkui Zhang Fei Ma Zhao Wang | 2023 | Acta Pharmaceutica Sinica B2023，13，6： | 0 |
| 8 | 三阴性乳腺癌患者因新辅助或辅助化疗引起的早发性心脏事件与其基因组DNA中某些新的自噬相关单核苷酸多态性的相关性研究:一项真实世界研究显示文摘背景与目的越来越多的癌症患者死于心血管疾病。三阴性乳腺癌(triple-negative breast cancer,TNBC)可选的治疗方法有限,因此化疗引起的心脏毒性对该类患者非常重要。心脏自噬是心脏毒性的重要机制之一。本研究旨在研究化疗对TNBC患者的心脏毒性,筛选易感人群,探讨心脏毒性与自噬相关基因多态性的相关性。方法在2450例I–III期TNBC患者中,有147例纳入了本研究。大多数患者在化疗周期前进行心电图(electrocardiography,ECG)检查,并根据临床需要进行超声心动图(echocardiography,UCG)检查。所有ECG和UCG资料均由阜外医院国家心血管病中心的心血管专家重新评判。根据美国国家生物技术信息中心数据库和癌症体细胞突变目录数据库,我们筛选了25个与自噬相关的单核苷酸多态性(single nucleotide polymorphisms,SNPs),并对147例TNBC患者进行了基因分型。采用配对样本T检验、卡方检验和logistic回归模型进行分析。结果每个化疗周期后,只有46(31.3%)例患者的ECG完全正常。在接受UCG的16例患者中,有2(12.5%)例患者左心室射血分数可逆性下降。使用蒽环类药物和过量饮酒是ECG异常的危险因素。随着化疗的持续,心率逐渐增加。蒽环类药物与QRS期持续异常有关(P=0.043)。我们对25个与自噬有关的SNP进行基因分型后发现,自噬相关基因13(ATG13)rs10838611的G等位基因与ECG异常显著相关(优势比=2.258,95%置信区间:1.318–3.869;P=0.003)。结论化疗引起的ECG异常在真实世界中很常见。自噬相关单核苷酸多态性与化疗引起的心脏毒性相关,本研究为自噬是化疗所致心脏损害的原因提供了新的证据。 | Binliang Liu Tao An Meiying Li Zongbi Yi Chunxiao Li Xiaoying Sun Xiuwen Guan Lixi Li Yanfeng Wang Yuhui Zhang Binghe Xu Fei Ma Yixin Zeng | 2019 | 癌症2019，38，7： | 0 |
