| 1 | Single-cell RNA sequencing in breast cancer: Understanding tumor heterogeneity and paving roads to individualized therapy显示文摘Single-cell RNA sequencing(scRNA-seq)is a novel technology that allows transcriptomic analyses of individual cells.During the past decade,scRNA-seq sensitivity,accuracy,and efficiency have improved due to innovations including more sensitive,automated,and cost-effective single-cell isolation methods with higher throughput as well as ongoing technological development of scRNA-seq protocols.Among the variety of current approaches with distinct features,researchers can choose the most suitable method to carry out their research.By profiling single cells in a complex population mix,scRNA-seq presents great advantages over traditional sequencing methods in dissecting heterogeneity in cell populations hidden in bulk analysis and exploring rare cell types associated with tumorigenesis and metastasis.scRNA-seq studies in recent years in the field of breast cancer research have clustered breast cancer cell populations with different molecular subtypes to identify distinct populations that may correlate with poor prognosis and drug resistance.The technology has also been used to explain tumor microenvironment heterogeneity by identifying distinct immune cell subsets that may be associated with immunosurveillance and are potential immunotherapy targets.Moreover,scRNA-seq has diverse applications in breast cancer research besides exploring heterogeneity,including the analysis of cell-cell communications,regulatory single-cell states,immune cell distributions,and more.scRNA-seq is also a promising tool that can facilitate individualized therapy due to its ability to define cell subsets with potential treatment targets.Although scRNA-seq studies of therapeutic selection in breast cancer are currently limited,the application of this technology in this field is prospective.Joint efforts and original ideas are needed to better implement scRNA-seq technologies in breast cancer research to pave the way for individualized treatment management.This review provides a brief introduction on the currently available scRNA-seq approaches along with their corresponding strengths and weaknesses and may act as a reference for the selection of suitable methods for research.We also discuss the current applications of scRNA-seq in breast cancer research for tumor heterogeneity analysis,individualized therapy,and the other research directions mentioned above by reviewing corresponding published studies.Finally,we discuss the limitations of current scRNA-seq technologies and technical problems that remain to be overcome. | Shuning Ding Xiaosong Chen Kunwei Shen | 2020 | Cancer Communications2020，40，8： | 12 |
| 2 | Single-cell atlas reveals a distinct immune profile fostered by T cell-B cell crosstalk in triple negative breast cancer显示文摘Background:Characterizing the unique immune microenvironment of each tumor is of great importance for better predicting prognosis and guiding cancer immunotherapy.However,the unique features of the immune microenvironment of triple negative breast cancer(TNBC)compared with other subtypes of breast cancer remain elusive.Therefore,we aimed to depict and compare the immune landscape among TNBC,human epidermal growth factor receptor 2-positive(HER2^(+))breast cancer,and luminal-like breast cancer.Methods:Single-cell RNA sequencing(scRNA-seq)was performed on CD45^(+)immune cells isolated from human normal breast tissues and primary breast tumors of various subtypes.By analyzing the scRNA-seq data,immune cell clusters were identified and their proportions as well as transcriptome features were compared among TNBC,human HER2^(+)breast cancer,and luminal-like breast cancer.Pseudotime and cell-cell communication analyses were also conducted to characterize the immune microenvironment.Results:ScRNA-seq data of 117,958 immune cells were obtained and 31 immune clusters were identified.A unique immunosuppressive microenvironment in TNBC was decoded as compared to that in HER2^(+)or luminal-like breast cancer,which was characterized by higher proportions of regulatory T cells(Tregs)and exhausted CD8+T cells and accompanied by more abundant plasma cells.Tregs and exhausted CD8+T cells in TNBC exhibited increased immunosuppression signature and dysfunctional scores.Pseudotime analyses showed that B cells tended to differentiate to plasma cells in TNBC.Cell-cell communication analyses indicated that these unique features are fostered by the diversified T cell-B cell crosstalk in TNBC.Based on the T cell-B cell crosstalk,a prognostic signaturewas established that could effectively predict the prognosis status for patients with TNBC.Additionally,it was found that TNBC had a higher proportion of cytotoxic natural killer(NK)cells,whereas HER2^(+)or luminal-like breast cancer lost this feature,suggesting thatHER2^(+)or luminal-like breast cancer,but not TNBC,may benefit from NK-based immunotherapy.Conclusions:This study identified a distinct immune feature fostered by T cell-B cell crosstalk in TNBC,which provides better prognostic information and effective therapeutic targets for breast cancer. | Shuning Ding Niu Qiao Qingchen Zhu Yiwei Tong Shengyue Wang Xiaosong Chen Qiang Tian Yichuan Xiao Kunwei Shen | 2023 | Cancer Communications2023，43，6： | 2 |

| 4 | Exome sequencing identifies rare mutations of LDLR and QTRT1 conferring risk for early-onset coronary artery disease in Chinese显示文摘Despite the advances made over the past decades,the known loci for coronary artery disease(CAD)still only explain<20%of the genetic variation in risk[1,2].The known loci with the strongest effects usually confer a 20%-37%increased CAD risk and the most loci modulate risk by≤10%[1].While most of the current data are from European populations,the use of trans-ethnic analyses could be helpful to identify additional loci.Genetic inheritance may impose a high burden on early-onset coronary artery disease(EOCAD). | Kang Yao Yuxiang Dai Juan Shen Yi Wang Huanjie Yang Runda Wu Qijun Liao Hongyi Wu Xiaodong Fang Shalaimaiti Shali Lili Xu Meng Hao Chenhao Lin Zhonghan Sun Yilian Liu Mengxin Li Zhen Wang Qiang Gao Shuning Zhang Chenguang Li Wei Gao Lei Ge Yunzeng Zou Aijun Sun Juying Qian Li Jin Shangyu Hong Yan Zheng Junbo Ge | 2022 | National Science Review2022，9，8： | 1 |
| 5 | Biodegradable interference distraction implant:a promising replacement for conventional implant in patients with insufficient alveolar bone height显示文摘Background Dental implants have been widely used in the last few decades.However,patients with insufficient bone height need reconstructive surgeries before implant insertion.Distraction implant(Dl)has been invented to simplify the treatment procedure,but the shortcomings of Dl have limited its clinical use.We introduced biodegradable polyester to a novel Dl,called biodegradable interference distraction implant(BIDI).The purpose of this study was to assess the radiological,histological,and biomechanical properties of BIDI in animal models.Methods BIDIs were manufactured and inserted into the atrophied mandibles of 6 dogs. | Yongfeng Li Tao Li Bo Shao Yingying Sun Yuan Gao Yongqiang Zhang Qi Gao Shuning Shen Qiang Niu Mingming Shen Liang Kong | 2013 | 医用生物力学2013，28，S1： | 0 |
