6Transforming growth factor-β in stem cells and tissue homeostasis显示文摘TGF-β 1–3 are unique multi-functional growth factors that are only expressed in mammals, and mainly secreted and stored as a latent complex in the extracellular matrix(ECM). The biological functions of TGF-β in adults can only be delivered after ligand activation, mostly in response to environmental perturbations. Although involved in multiple biological and pathological processes of the human body, the exact roles of TGF-β in maintaining stem cells and tissue homeostasis have not been well-documented until recent advances, which delineate their functions in a given context. Our recent findings, along with data reported by others, have clearly shown that temporal and spatial activation of TGF-β is involved in the recruitment of stem/progenitor cell participation in tissue regeneration/remodeling process, whereas sustained abnormalities in TGF-β ligand activation, regardless of genetic or environmental origin, will inevitably disrupt the normal physiology and lead to pathobiology of major diseases. Modulation of TGF-β signaling with different approaches has proven effective pre-clinically in the treatment of multiple pathologies such as sclerosis/fibrosis, tumor metastasis, osteoarthritis, and immune disorders. Thus, further elucidation of the mechanisms by which TGF-β is activated in different tissues/organs and how targeted cells respond in a context-dependent way can likely be translated with clinical benefits in the management of a broad range of diseases with the involvement of TGF-β.Xin Xu Liwei Zheng Quan Yuan Gehua Zhen Janet L.Crane Xuedong Zhou Xu Cao 2018Bone Research2018,6,1:22

10Robotic surgery for rectal cancer: A systematic review of current practice显示文摘AIM: To give a comprehensive review of current litera-ture on robotic rectal cancer surgery.METHODS: A systematic review of current literature via PubMed and Embase search engines was per-formed to identify relevant articles from january 2007 to november 2013. The keywords used were: 'robotic surgery', 'surgical robotics', 'laparoscopic computer-assisted surgery', 'colectomy' and 'rectal resection'. RESULTS: After the initial screen of 380 articles, 20 pa-pers were selected for review. A total of 1062 patients(male 64.0%) with a mean age of 61.1 years and body mass index of 24.9 kg/m2 were included in the review.Out of 1062 robotic-assisted operations, 831(78.2%) anterior and low anterior resections, 132(12.4%) in-tersphincteric resection with coloanal anastomosis, 98(9.3%) abdominoperineal resections and 1(0.1%) Hart-mann's operation were included in the review. Robotic rectal surgery was associated with longer operative time but with comparable oncological results and anastomotic leak rate when compared with laparoscopic rectal surgery. CONCLUSION: Robotic colorectal surgery has con-tinued to evolve to its current state with promising re-sults; feasible surgical option with low conversion rate and comparable short-term oncological results. The challenges faced with robotic surgery are for more high quality studies to justify its cost.Tony Wing Chung Mak Janet Fung Yee Lee Kaori Futaba Sophie Sok Fei Hon Dennis Kwok Yu Ngo Simon Siu Man Ng 2014World Journal of Gastrointestinal Oncology2014,6,6:16

13Ciliary parathyroid hormone signaling activates transforming growth factor-βto maintain intervertebral disc homeostasis during aging显示文摘Degenerative disc disease(DDD) is associated with intervertebral disc degeneration of spinal instability. Here, we report that the cilia of nucleus pulposus(NP) cells mediate mechanotransduction to maintain anabolic activity in the discs. We found that mechanical stress promotes transport of parathyroid hormone 1 receptor(PTH1 R) to the cilia and enhances parathyroid hormone(PTH) signaling in NP cells. PTH induces transcription of integrin α_vβ_6 to activate the transforming growth factor(TGF)-β-connective tissue growth factor(CCN2)-matrix proteins signaling cascade. Intermittent injection of PTH(iPTH) effectively attenuates disc degeneration of aged mice by direct signaling through NP cells, specifically improving intervertebral disc height and volume by increasing levels of TGF-β activity, CCN2, and aggrecan. PTH1 R is expressed in both mouse and human NP cells. Importantly,knockout PTH1 R or cilia in the NP cells results in significant disc degeneration and blunts the effect of PTH on attenuation of aged discs. Thus, mechanical stress-induced transport of PTH1 R to the cilia enhances PTH signaling, which helps maintain intervertebral disc homeostasis, particularly during aging, indicating therapeutic potential of iPTH for DDD.Liwei Zheng Yong Cao Shuangfei Ni Huabin Qi Zemin Ling Xin Xu Xuenong Zou Tianding Wu Ruoxian Deng Bo Hu Bo Gao Hao Chen Yusheng Li Jianxi Zhu Francis Tintani Shadpour Demehri Amit Jain Khaled M.Kebaish Shenghui Liao Cheryle A.Séguin Janet L.Crane Mei Wan Hongbin Lu Paul D.Sponseller Lee H.RileyIII Xuedong Zhou Jianzhong Hu Xu Cao 2018Bone Research2018,6,3:13

15Telerobotic-assisted laparoscopic abdominoperineal resection for low rectal cancer: Report of the first case in Hong Kong and China with an updated literature review显示文摘Telerobotic surgery is the most advanced development in the field of minimally invasive surgery. The da Vinci surgical system, which is currently the most widely used telerobotic device, was approved by the Food and Drug Administration of the United States of America for clinical use in all abdominal operations in July 2000. The first da Vinci surgical system in China was installed in November 2005 at our institution. We herein report the first telerobotic-assisted laparoscopic abdominoperineal resection using the 3-arm da Vinci surgical system for low rectal cancer in Hong Kong and China, which was performed in August 2006. The operative time and blood loss were 240 min and 200 mL, respectively. There was no complication, and the patient was discharged on postoperative day five. An updated review of published literature on telerobotic-assisted colorectal surgery is included in this report, with special emphasis on its advantages and limitations.Simon Siu-Man Ng Janet Fung-Yee Lee Raymond Ying-Chang Yiu Jimmy Chak-Man Li Sophie Sok-Fei Hon 2007World Journal of Gastroenterology2007,13,17:12

17Multiparametric analysis of colorectal cancer immune responses显示文摘Colorectal cancer(CRC) is a heterogeneous disease, with a diverse and plastic immune cell infiltrate. These immune cells play an important role in regulating tumour growth-progression or elimination. Some populations of cells have a strong correlation with disease-free survival, making them useful prognostic markers. In particular, the infiltrate of CD3^+ and CD8^+ T cells into CRC tumours has been validated worldwide as a valuable indicator of patient prognosis. However, the heterogeneity of the immune response, both between patients with tumours of different molecular subtypes, and within the tumour itself, necessitates the use of multiparametric analysis in the investigation of tumour-specific immune responses. This review will outline the multiparametric analysis techniques that have been developed and applied to studying the role of immune cells in the tumour, with a focus on colorectal cancer. Because much of the data in this disease relates to T cell subsets and heterogeneity, we have used T cell populations as examples throughout. Flow and mass cytometry give a detailed representation of the cells within the tumour in a single-cell suspension on a per-cell basis. Imaging technologies, such as imaging mass cytometry, are used to investigate increasing numbers of markers whilst retaining the spatial and structural information of the tumour section and the infiltrating immune cells. Together, the analyses of multiple immune parameters can provide valuable information to guide clinical decision-making in CRC.Julia KH Leman Sarah K Sandford Janet L Rhodes Roslyn A Kemp 2018World Journal of Gastroenterology2018,24,27:12
18Tertiary lymphoid structures in cancer – considerations for patient prognosis显示文摘Tertiary lymphoid structures(TLS)are ectopic lymphoid formations that form within nonlymphoid tissue.They share structural and functional characteristics with secondary lymphoid structures such as lymph nodes and can contain B-cell follicles and germinal centers surrounded by a T-cell region.TLS have been described in several types of cancers and are usually associated with positive patient outcomes.However,TLS differ vastly in cellular composition and location within tissue types.In this review,we discuss factors confounding the interpretation of the evidence for a prognostic role for TLS in cancer and frame these factors in the context of translation to regular clinical use.Luis Munoz-Erazo Janet L.Rhodes Valentine C.Marion Roslyn A.Kemp 2020Cellular & Molecular Immunology2020,17,6:11
