+ [12]

简介

Tyrosine-protein kinase that acts as a cell-surface receptor for VEGFC and VEGFD, and plays an essential role in adult lymphangiogenesis and in the development of the vascular network and the cardiovascular system during embryonic development. Promotes proliferation, survival and migration of endothelial cells, and regulates angiogenic sprouting. Signaling by activated FLT4 leads to enhanced production of VEGFC, and to a lesser degree VEGFA, thereby creating a positive feedback loop that enhances FLT4 signaling. Modulates KDR signaling by forming heterodimers. The secreted isoform 3 may function as a decoy receptor for VEGFC and/or VEGFD and play an important role as a negative regulator of VEGFC-mediated lymphangiogenesis and angiogenesis. Binding of vascular growth factors to isoform 1 or isoform 2 leads to the activation of several signaling cascades; isoform 2 seems to be less efficient in signal transduction, because it has a truncated C-terminus and therefore lacks several phosphorylation sites. Mediates activation of the MAPK1/ERK2, MAPK3/ERK1 signaling pathway, of MAPK8 and the JUN signaling pathway, and of the AKT1 signaling pathway. Phosphorylates SHC1. Mediates phosphorylation of PIK3R1, the regulatory subunit of phosphatidylinositol 3-kinase. Promotes phosphorylation of MAPK8 at 'Thr-183' and 'Tyr-185', and of AKT1 at 'Ser-473'.

Associations between metal/metalloid exposure during pregnancy and placental growth characteristics: Findings from the Hangzhou birth cohort study II

Article

作者: Zhou, Jiena ; Zhong, Kunhong ; Tang, Jun ; Huang, Kegui ; Luo, Qiong ; Xu, Yang ; Jin, Lanfei ; Zhao, Hao ; Zhang, Dan ; Chen, Guangdi ; Zhu, Qinheng ; Zhou, Yexinyi ; Guo, Jing

Previous studies have suggested that metal/metalloid (hereafter referred to as metal) exposure may influence placental growth by affecting gene expression in the placenta. However, no epidemiological studies have been conducted to validate the relationships between metals exposure, placental gene expression, and placental growth at the population level. This study aims to investigate these relationships based on Hangzhou birth cohort study II (HBCS-II). Totally, 1025 participants were derived from HBCS-II. Thirteen metals levels in the placenta were measured using inductively coupled plasma mass spectrometry. Placental growth characteristics were assessed, including placental weight, chorionic disc area, placental eccentricity, and distance from cord insertion site to the nearest edge of placenta (DCIEP). The relationships between metals exposure and placental growth characteristics were examined using the elastic net model combined unpenalized linear regression model. Placental gene expression levels were analyzed through RNA sequencing and real-time polymerase chain reaction (RT-qPCR), and mediation analysis was conducted to investigate whether placental gene expression could mediate the relationship between metal exposure and placental growth. Notably, the results showed that a unite increase in Ln-transformed cadmium (Cd) levels was associated with a reduction of 16.4 g [95% confidence interval (CI): 31.2, -1.5] in placental weight, 13.9 cm² (95%CI: 20.0, -7.8) in chorionic disc area, and 0.3 cm (95%CI: 0.55, -0.06) in DCIEP. Through RNA sequencing followed by validation, significant associations were observed between placental Cd level and increased expression of placental genes, including TNFAIP2, OLAH, FLT4, SH3PXD2A, LIMCH1, BCL6, SLCO2A1, and CPSF1. Additionally, increased placental TNFAIP2, OLAH, FLT4, SH3PXD2A and LIMCH1 expression was linked to reduced placental weight. Moreover, SH3PXD2A was associated with decreased chorionic disc area. Mediation analysis showed that placental Cd level was associated with a 12.0 g (95%CI: 23.8, -2.7) decrease in placental weight mediated through the upregulation of FTL4 gene expression. The study provides evidence of the association between placental Cd exposure and decreased placental weight, and the FLT4 gene may play a mediating role in this relationship. Future experiment studies should be performed to validate the results.

VEGFD signaling balances stability and activity-dependent structural plasticity of dendrites

Article

作者: Mauceri, Daniela ; Missirlis, Dimitris ; Sánchez Romero, Javier ; Yan, Jing ; Aksan, Bahar ; Kenkel, Ann-Kristin

AbstractMature neurons have stable dendritic architecture, which is essential for the nervous system to operate correctly. The ability to undergo structural plasticity, required to support adaptive processes like memory formation, is still present in mature neurons. It is unclear what molecular and cellular processes control this delicate balance between dendritic structural plasticity and stabilization. Failures in the preservation of optimal dendrite structure due to atrophy or maladaptive plasticity result in abnormal connectivity and are associated with various neurological diseases. Vascular endothelial growth factor D (VEGFD) is critical for the maintenance of mature dendritic trees. Here, we describe how VEGFD affects the neuronal cytoskeleton and demonstrate that VEGFD exerts its effects on dendrite stabilization by influencing the actin cortex and reducing microtubule dynamics. Further, we found that during synaptic activity-induced structural plasticity VEGFD is downregulated. Our findings revealed that VEGFD, acting on its cognate receptor VEGFR3, opposes structural changes by negatively regulating dendrite growth in cultured hippocampal neurons and in vivo in the adult mouse hippocampus with consequences on memory formation. A phosphoproteomic screening identified several regulatory proteins of the cytoskeleton modulated by VEGFD. Among the actin cortex-associated proteins, we found that VEGFD induces dephosphorylation of ezrin at tyrosine 478 via activation of the striatal-enriched protein tyrosine phosphatase (STEP). Activity-triggered structural plasticity of dendrites was impaired by expression of a phospho-deficient mutant ezrin in vitro and in vivo. Thus, VEGFD governs the equilibrium between stabilization and plasticity of dendrites by acting as a molecular brake of structural remodeling.

ERG Regulates Lymphatic Vessel Specification Genes and Its Deficiency Impairs Wound Healing‐Associated Lymphangiogenesis

Article

作者: Chakraborty, Adri ; Bujor, Andreea ; Gritli, Sami ; Yamashita, Takashi ; Browning, Jeffrey L. ; Trojanowski, Marcin ; Trojanowska, Maria ; Roh, Daniel ; Kaplan, Ulas ; Ligresti, Giovanni ; Browning, Jeffrey L ; Marden, Grace

ObjectiveRarefaction of blood and lymphatic vessels in the skin has been reported in systemic sclerosis (SSc) (scleroderma). E26 transformation–specific–related factor (ERG) and Friend leukemia virus–induced erythroleukemia 1 (FLI‐1) are important regulators of angiogenesis, but their role in lymphatic vasculature is lesser known. The goal of this study was to determine the role of ERG and FLI‐1 in postnatal lymphangiogenesis and SSc lymphatic system defects.MethodsImmunofluorescence was used to detect ERG and FLI‐1 in skin biopsy samples from patients with SSc and healthy controls. Transcriptional analysis of ERG or FLI‐1–silenced human dermal lymphatic endothelial cells (LECs) was performed using microarrays. Effects of ERG and FLI‐1 deficiency on in vitro tubulogenesis in human dermal LECs were examined using a Matrigel assay. ERG and FLI‐1 endothelial–specific knockouts and ERG lymphatic–specific knockouts were generated to examine vessel regeneration in mice.ResultsERG and FLI‐1 protein levels were reduced in the blood and lymphatic vasculature in SSc skin biopsy samples. ERG levels were shown to regulate genes involved in lymphatic vessel specification, including vascular endothelial growth factor receptor 3/FLT‐4, lymphatic vessel endothelial hyaluronan receptor 1, SOX‐18, and prospero homeobox 1 (PROX‐1), whereas FLI‐1 enhanced the function of ERG. The ERG–FLT‐4 pathway regulated in vitro tubulogenesis in human LECs. Deficiency of ERG or FLI‐1 similarly impaired the function of blood vessels in mice. However, only ERG deficiency affected the regeneration of lymphatic vessels during wound healing.ConclusionERG and FLI‐1 are essential regulators of blood and lymphatic vessel regeneration. Deficiency of ERG and FLI‐1 in SSc endothelial cells may contribute to the impairment of blood and lymphatic vasculature in patients with SSc.

ILCA 2024丨元云飞教授：REFINE研究报道介入治疗亚组数据，真实世界TACE联合靶向治疗有生存获益

编者按：第18届国际肝癌协会（ILCA）年会于2024年10月17—19日在加拿大多伦多举行。本次大会上,美国加州大学洛杉矶分校（UCLA）大卫·格芬医学院的Richard S. Finn教授再次报道了真实世界REFINE研究的亚组分析，结果表明在接受瑞戈非尼治疗的不可切除肝细胞癌（uHCC）患者中，接受过经动脉化疗栓塞（TACE）和经动脉放射栓塞（TARE）的患者具有更好的生存获益趋势。《肿瘤瞭望》特邀中山大学肿瘤防治中心元云飞教授介绍和点评该研究如下。研究简介在常规临床实践中接受瑞戈非尼治疗的不可切除肝细胞癌患者的观察性研究（REFINE）：根据先前的经动脉化疗栓塞（TACE）和经动脉放射栓塞（TARE）的亚组分析背景瑞戈非尼被批准用于治疗不可切除肝细胞癌（uHCC）患者，这些患者在接受索拉非尼治疗后发生病情进展，这一批准是基于 III期RESORCE试验中总生存期（OS）改善。国际前瞻性观察性研究REFINE研究（NCT03289273）证实了瑞戈非尼在广泛uHCC患者群体中的安全性和有效性，这与RESORCE的结果一致。这项REFINE研究的亚组分析根据先前的经动脉化疗栓塞（TACE）和经动脉放射栓塞（TARE）对患者进行了评估。方法 REFINE研究包括了由医生在登记前决定使用瑞戈非尼治疗的uHCC患者，且符合当地卫生当局批准的标签。主要目标是评估安全性（根据MedDRA v25编码；根据NCI CTCAE v4.03分级）以及由于治疗紧急不良事件（TEAEs）导致的剂量调整。次要终点包括OS和治疗持续时间（DoT）。结果共有1005例患者可供评估。基线时，中位年龄为66岁，83%为男性，62%为BCLC C期，82%的ECOG PS为0或1，55%来自亚洲。大多数患者曾接受过索拉非尼治疗（96%），10%的患者曾接受过免疫检查点抑制剂。大多数患者（58%）既往接受过TACE，3%的患者接受过TARE。在接受过TACE的患者中，68%来自亚洲，而只有29%接受过TARE的患者来自亚洲。总体而言，基线特征在亚组间是一致的。接受过TACE或TARE治疗的患者的整体安全性概况与未接受过的患者相似。接受过TACE治疗的患者具有更长的中位OS（log-rank P = 0.03），中位OS（95% CI）达到了41.7个月（38.7, 45.5）。接受过TARE相关的OS益处的趋势也相似（log-rank P = 0.47），中位OS（95% CI）为35.1个月（25.7, 51.2）。结论在瑞戈非尼治疗的患者中，与没有接受过TACE的患者相比，接受过TACE治疗的患者具有OS获益。这种趋势在接受过TARE治疗的患者中也较明显，尽管分析中的患者数量很少。研究点评瑞戈非尼是一种口服的多激酶抑制剂，可阻断肿瘤生长和进展过程中的多种蛋白激酶，包括血管形成（VEGFR1—3、TIE2）、肿瘤增殖（KIT、RET、RAF-1、BRAF）、肿瘤微环境（VEGFR3、PDGFR、FGFR）以及肿瘤免疫（CSF1R）的激酶。国际多中心3期RESORCE研究[2]的阳性结果，使得瑞戈非尼成为第一个获批的uHCC二线靶向治疗药物，真实世界REFINE研究[3]进一步验证了瑞戈非尼的疗效和安全性。RESORCE研究发表至今已过去7年（Lancet,2017），在此期间，国内外进行了大量的中晚期HCC介入联合系统治疗的探索，其中TACE联合靶向治疗是较为常见的探索方案。理论上，TACE等介入治疗除了能够降低肿瘤负荷以外，还可以和靶向治疗、免疫治疗发挥协同抗肿瘤作用，主要由于这些综合治疗手段能够促进肿瘤血管正常化、改善免疫微环境和促进肿瘤抗原的释放[4-5]。因此，在TACE治疗基础上联合靶向、免疫等系统治疗，或可进一步提高疗效和增加生存获益。这次ILCA报道的REFINE研究亚组分析再次验证了这一理念，在瑞戈非尼治疗的患者中，接受过TACE或TARE的患者表现出更好的生存获益。联合治疗的耐受性是临床较为关注的问题之一，在这项研究中，总体上接受过或未接受过TACE（50% vs 58%）患者的≥3级治疗期间不良事件（TEAEs）发生率相当，表明TACE联合瑞戈非尼没有增加不良反应。当然，这是一项真实世界研究，具体的介入治疗时机、次数等情况并不清楚，但总体上患者是可以耐受的，接受过或未接受过TACE（30% vs 32%）患者的停药率相当。国内曾回顾性报道过瑞戈非尼联合TACE用于uHCC二线治疗，结果显示有较好的ORR（42.3%）和DCR（66.1%），仅有9例患者出现3/4级不良反应[6]。这些结果都验证了TACE联合瑞戈非尼用于晚期HCC治疗的可行性。随着靶向、免疫治疗的发展，近年来有了更多的TACE联合治疗探索，尤其是TACE作为中期HCC治疗标准，在此基础上联合靶向、免疫治疗已经积累了丰富的循证医学证据。例如，今年ESMO大会报道的3期LEAP-012研究[7]中，在TACE基础上联合“可乐组合”（帕博利珠单抗＋仑伐替尼）用于中期肝癌可显著改善无进展生存期（PFS：14.6 vs 10.0个月；HR 0.66，P=0.0002）；而既往报道的3期EMERALD-1研究[8]中，局晚期肝癌患者在TACE基础上联合“D+B”（度伐利尤单抗＋贝伐珠单抗），同样可以显著改善PFS（15.0 vs 8.2个月，HR 0.77，P=0.032）。综上所述，TACE等介入治疗与靶向、免疫联合治疗具有良好的协同增效机制，随着药物组合的丰富以及治疗范围的拓展，该联合治疗方案有望为HCC带来更多治疗变革，造福更多患者。参考文献上下滑动查看更多内容 [1]Richard S.
