UNASSIGNED: The purpose of this study was to investigate the molecular mechanisms underlying anti-vascular endothelial growth factor (anti-VEGF) efficacy and response variability in neovascular age-related macular degeneration (nAMD) using longitudinal proteomic and metabolomic analysis alongside three-dimensional lesion measurements.
UNASSIGNED: In this prospective study, 54 treatment-naive patients with nAMD underwent \"3+ pro re nata\" (3+PRN) anti-VEGF regimens followed for at least 12 weeks. Aqueous humors were collected pre- and post-treatment for proteomic and metabolomic analysis. Three-dimensional optical coherence tomography (OCT) and OCT angiography assessed different types of nAMD lesion volumes and areas.
UNASSIGNED: There were 1350 proteins and 1268 metabolites that were identified in aqueous humors, with 301 proteins and 353 metabolites significantly altered during anti-VEGF treatment, enriched in pathways of angiogenesis, energy metabolism, signal transduction, and neurofunctional regulation. Sixty-seven changes of (Δ) molecules significantly correlated with at least one type of ΔnAMD lesion. Notably, proteins FGA, TALDO1, and ASPH significantly decreased during treatment, with their reductions correlating with greater lesion regression in at least two lesion types. Conversely, despite that YIPF3 also showed significant downregulation, its decrease was associated with poorer regression in total nAMD lesion and subretinal hyper-reflective material.
UNASSIGNED: This study identifies FGA, TALDO1, and ASPH as potential key molecules in the efficacy of anti-VEGF therapy, whereas YIPF3 may be a key factor in poor response. The integration of longitudinal three-dimensional lesion analysis with multi-omics provides valuable insights into the mechanisms and response variability of anti-VEGF treatment in nAMD.

UNASSIGNED: Ovarian cancer (OC) is a gynecological malignancy with a high mortality rate worldwide. The unfavorable prognosis of OC is mainly attributed to the recurrent propensity. Recently, mortality from OC has exhibited a downward trend. These favorable patterns are likely to be driven by advancements in novel therapeutic regimens. However, there is a lack of visualize analysis of the application of these new drugs on women with recurrent OC (ROC). Therefore, we aimed to provide a bibliometric analysis of the evolving paradigms in the ROC treatment.
UNASSIGNED: Documents on ROC treatment were systematically collected from the MEDLINE database and Web of Science Core Collection (WOSCC). The retrieved documents were exported in the plain text file format, and files were named and saved to the paths specified by the Java application. Microsoft Excel (version 2010), Citespace (6.2.R4) and VOSviewer (1.6.19) were used for data analysis, and included the following: 1) annual publication trend; 2) contributions of countries, institutions and authors; 3) co-citation of journals and references; and 4) co-occurrence of keywords.
UNASSIGNED: A total of 914 documents published in the MEDLINE and 9,980 ones in WOSCC were retrieved. There has been an upward trend in the productivity of publications on ROC treatment on by years. The United States was the leading contributor in this field, and the University of Texas System stood out as the most productive institution. Giovanni Scambia and Maurie Markman were the research leaders in the field of ROC treatment. The journal Gynecologic Oncology had the highest citation frequency. The reference entitled with \"Niraparib Maintenance Therapy in Platinum-Sensitive, Recurrent Ovarian Cancer\" got highest centrality of 0.14 in the co-citation network. Keyword analysis revealed that the focus of current ROC treatment was on platinum-based anticancer drugs, paclitaxel, angiogenesis inhibitors (AIs), immune checkpoint inhibitors (ICIs) and poly (ADP-ribose) polymerase inhibitors (PARPis).
UNASSIGNED: Scholars from a multitude of countries have been instrumental in the advancement of ROC treatment. The research hotspots and trend in the field of predominantly originated from leading international journals and specialized periodicals focused on gynecologic oncology. Maintenance therapy using AIs or (and) PARPis has emerged as a significant complement to platinum-based chemotherapy for patients with ROC.

BACKGROUND: Intravitreal injection of anti-vascular endothelial growth factor is considered the first-line treatment for polypoidal choroidal vasculopathy. It has potential risks for circulatory system, which should be particularly carefully evaluated in older patients. In this case study, we aim to discuss the potential impact of this treatment regimen on cardiac health.
METHODS: This case report describes an elderly patient with no prior history of heart disease who exhibited unexpected heart enlargement and dysfunction. Throughout the patient\'s hospital stay, various potential causes were investigated, leading to the hypothesis that a 10-year history of intravitreal injections of anti-vascular endothelial growth factor could be related to the observed clinical manifestations. The patient was advised to discontinue this treatment, and after a 2-month follow-up period, there was a gradual improvement in the patient\'s cardiac structure and function.
CONCLUSIONS: This manuscript highlights the importance of conducting cardiac examinations before and after anti-vascular endothelial growth factor treatment, especially for individuals at risk of heart diseases like the elderly. It emphasizes the need to carefully weigh the benefits and risks of treatment regimens to ensure optimal therapeutic outcomes.

To investigate biometric and refractive results in patients with type 1 retinopathy of prematurity (ROP) treated by intravitreal injection (IVI) of ranibizumab (R) and bevacizumab (B) at the corrected age of 6. This is a single-center retrospective study. Infants diagnosed with type 1 ROP and treated with IVI of either R or B as the primary therapy were included. Data on axial length, anterior chamber depth (ACD), and lens thickness (LT) were obtained using A-scan ultrasound. Cycloplegic refraction, keratometry (K), and best-corrected visual acuity were also documented. Additionally, optical coherence tomography angiography was performed to assess the foveal avascular zone and the density of superficial and deep vessels. We analyzed the structural and functional differences between the 2 groups and compared them with findings from a previous study conducted when these children were between the ages of 1 and 3. The study included 60 eyes from 34 patients, with 34 eyes receiving B and 26 eyes receiving R injections for ROP. In biometric outcomes, there was still a deeper ACD (3.36 ± 0.24 mm in the B group; 3.52 ± 0.21 mm in the R group) and thinner LT (3.63 ± 0.16 mm in the B group; 3.53 ± 0.12 mm in the R group) in the R group, as previously reported at the age of 3. In the refractive aspect, the eyes treated with B had higher myopia at the ages of 1 and 3; however, at the age of 6, refractive errors did not differ significantly between the 2 groups. At the corrected age of 6, the eyes treated with IVI of R were associated with deeper ACD and thinner LT. Interestingly, the emmetropization process resulted in a similar incidence of high myopia at the age of 6, which was different from the outcomes observed at younger ages.

BACKGROUND: Small cell lung cancer (SCLC) is a highly aggressive tumor with limited effectiveness in its standard chemotherapy treatment. Targeted antiangiogenic therapy and immune checkpoint inhibitors (ICIs) have demonstrated potential as alternative treatments for extensive-stage SCLC (ES-SCLC). However, there is insufficient comparative evidence available to determine the optimal first-line treatment option between ICIs plus chemotherapy and targeted antiangiogenic therapy plus chemotherapy.
OBJECTIVE: This study is aimed at analyzing clinical data from ES-SCLC patients treated at the First Affiliated Hospital of Bengbu Medical College between June 2021 and June 2023. The study compared the efficacy and safety of three first-line treatment regimens: standard chemotherapy, antiangiogenic therapy combined with chemotherapy, and immune combination therapy.
METHODS: Patients who met the inclusion criteria were divided into three groups: chemotherapy, immune combination therapy, and antiangiogenic therapy combined with chemotherapy. The study collected data on clinical characteristics, treatment regimens, and adverse reactions. The analysis included objective response rate (ORR), duration of response (DoR), disease control rate (DCR), progression-free survival (PFS), and treatment safety.
RESULTS: A total of 101 patients were included in the study, with 49 receiving chemotherapy alone, 19 receiving antiangiogenic therapy, and 33 receiving immune combination therapy. The ORRs were 78.9% for antiangiogenic therapy, 72.7% for immune combination therapy, and 42.9% for chemotherapy alone. The median PFS was 8.0 months for antiangiogenic therapy, 7.8 months for immune combination therapy, and 5.2 months for chemotherapy alone. Both combination therapy groups demonstrated superior efficacy compared to chemotherapy alone.
CONCLUSIONS: Targeted combined chemotherapy and immune combination chemotherapy showed superior efficacy as first-line treatments for ES-SCLC compared to chemotherapy alone, with manageable adverse reactions.

Tumor growth and metastasis rely on angiogenesis. In recent years, long non-coding RNAs have been shown to play an important role in regulating tumor angiogenesis. Here, we review the multidimensional modes and relevant molecular mechanisms of long non-coding RNAs in regulating tumor angiogenesis. In addition, we summarize new strategies for tumor anti-angiogenesis therapies by targeting long non-coding RNAs. The aim of this study is to provide new diagnostic targets and treatment strategies for anti-angiogenic tumor therapy.

BACKGROUND: The poor prognosis of anaplastic thyroid cancer (ATC) patients is associated with limited effective therapeutic strategies. Multiple antiangiogenesis tyrosine kinase inhibitors (TKIs) have been applied in later-line treatment of ATC; however, the results reported in clinical trials were controversial. In this study, we reconstructed the patient-level data to pooled-analyze the survival data, responses, and adverse events.
METHODS: Online databases (PubMed, Web of Science, Embase, and Cochrane CENTRAL) were searched on September 03, 2023. R software combined with the \"metaSurvival\" and \"meta\" packages were used to reconstruct the survival curves and summarize the response rates. The primary endpoints were progression-free survival (PFS) and overall survival (OS). The secondary endpoints were survival rate, objective response rate (ORR), disease control rate (DCR), and treatment-related adverse events.
RESULTS: Six prospective clinical trials involving 140 ATC patients were enrolled. Four types of TKIs (imatinib, pazopanib, sorafenib, and lenvatinib) were included. When advanced ATC patients were treated with the TKIs, the median OS was 4.8 months and the median PFS was 2.6 months. The pooled ORR and DCR were 9% and 53%. Hypertension, decreased appetite, rash, and lymphopenia were the most common grade ≥ 3 treatment-related adverse events.
CONCLUSIONS: Mono-anitangiogenesis TKI therapy showed limited improvements in treating advanced ATC patients. Combining antiangiogenesis TKI therapy with chemotherapy, radiotherapy, or immunotherapy could be the direction of future studies.

UNASSIGNED: Corneal neovascularization (CNV) is a common eye disease that leads to blindness. New treatment strategies are urgently needed due to the limitations of current treatment methods.
UNASSIGNED: We report the synthesis of peptide Nap-FFEEPCAIWF ( Comp.3 ) via chemical conjugation of Nap-FFEE ( Comp.2 ) to antiangiogenic peptide PCAIWF (Comp.1). Comp.3 self-assembled into a hydrogel ( gel of 3 ) composed of nanofibers, which enhanced the antiangiogenic function of the epitope.
UNASSIGNED: We developed a novel peptide with an amphiphilic framework, Comp.3 , which could self-assemble into a supramolecular hydrogel with a well-ordered nanofiber structure. The nanofibers exhibited good biocompatibility with corneal epithelial cells, presenting a promising strategy to enhance the efficacy of free peptide-based drugs in the treatment of ocular vascular diseases, such as CNV and other angiogenesis-related diseases.
UNASSIGNED: Nap-FFEEPCAIWF nanofibers provide an alternative approach to enhancing the therapeutic efficiency of free peptide-based drugs against ocular vascular diseases.

BACKGROUND: It has been proposed that anti-angiogenesis therapy could induce tumor \"vascular normalization\" and further enhance the efficacy of chemotherapy, radiotherapy, target therapy, and immunotherapy for nearly twenty years. However, the detailed molecular mechanism of this phenomenon is still obscure.
METHODS: Overexpression and knockout of CCL28 in human lung adenocarcinoma cell line A549 and murine lung adenocarcinoma cell line LLC, respectively, were utilized to establish mouse models. Single-cell sequencing was performed to analyze the proportion of different cell clusters and metabolic changes in the tumor microenvironment (TME). Immunofluorescence and multiplex immunohistochemistry were conducted in murine tumor tissues and clinical biopsy samples to assess the percentage of pericytes coverage. Primary pericytes were isolated from lung adenocarcinoma tumor tissues using magnetic-activated cell sorting (MACS). These pericytes were then treated with recombinant human CCL28 protein, followed by transwell migration assays and RNA sequencing analysis. Changes in the secretome and metabolome were examined, and verification of retinoic acid metabolism alterations in pericytes was conducted using quantitative real-time PCR, western blotting, and LC-MS technology. Chromatin immunoprecipitation followed by quantitative PCR (ChIP-qPCR) was employed to validate the transcriptional regulatory ability and affinity of RXRα to specific sites at the ANGPT1 promoter.
RESULTS: Our study showed that after undergoing anti-angiogenesis treatment, the tumor exhibited a state of ischemia and hypoxia, leading to an upregulation in the expression of CCL28 in hypoxic lung adenocarcinoma cells by the hypoxia-sensitive transcription factor CEBPB. Increased CCL28 could promote tumor vascular normalization through recruiting and metabolic reprogramming pericytes in the tumor microenvironment. Mechanistically, CCL28 modified the retinoic acid (RA) metabolism and increased ANGPT1 expression via RXRα in pericytes, thereby enhancing the stability of endothelial cells.
CONCLUSIONS: We reported the details of the molecular mechanisms of \"vascular normalization\" after anti-angiogenesis therapy for the first time. Our work might provide a prospective molecular marker for guiding the clinical arrangement of combination therapy between anti-angiogenesis treatment and other therapies.

BACKGROUND: Diabetic retinopathy (DR) is a common vascular complication of diabetes mellitus and a leading cause of vision loss worldwide. Endothelial cell (EC) heterogeneity has been observed in the pathogenesis of DR. Elucidating the underlying mechanisms governing EC heterogeneity may provide novel insights into EC-specific therapies for DR.
METHODS: We used the single-cell data from the Gene Expression Omnibus database to explore EC heterogeneity between diabetic retinas and non-diabetic retinas and identify the potential genes involved in DR. CCK-8 assays, EdU assays, transwell assays, and tube formation assays were conducted to determine the role of the identified gene in angiogenic effects.
RESULTS: Our analysis identified three distinct EC subpopulations in retinas and revealed that Mitochondria-localized glutamic acid-rich protein (Mgarp) gene is potentially involved in the pathogenesis of DR. Silencing of Mgarp significantly suppressed the proliferation, migration, and tube formation capacities in retinal endothelial cells.
CONCLUSIONS: This study not only offers new insights into transcriptomic heterogeneity and pathological alteration of retinal ECs but also holds the promise to pave the way for antiangiogenic therapy by targeting EC-specific gene.
