Abstract
Phospholipases A2 (PLA2s) from snake venom possess antitumor and antiangiogenic properties. In this study, we evaluated the antimetastatic and antiangiogenic effects of MjTX-II, a Lys49 PLA2 isolated from Bothrops moojeni venom, on lung cancer and endothelial cells. Using in vitro and ex vivo approaches, we demonstrated that MjTX-II reduced cell proliferation and inhibited fundamental processes for lung cancer cells (A549) growth and metastasis, such as adhesion, migration, invasion, and actin cytoskeleton decrease, without significantly interfering with non-tumorigenic lung cells (BEAS-2B). Furthermore, MjTX-II caused cell cycle alterations, increased reactive oxygen species production, modulated the expression of pro- and antiangiogenic genes, and decreased vascular endothelial growth factor (VEGF) expression in HUVECs. Finally, MjTX-II inhibited ex vivo angiogenesis processes in an aortic ring model. Therefore, we conclude that MjTX-II exhibits antimetastatic and antiangiogenic effects in vitro and ex vivo and represents a molecule that hold promise as a pharmacological model for antitumor therapy.

Antiangiogenic properties of BthMP, a P-I metalloproteinase from Bothrops moojeni snake venom by VEGF pathway in endothelial cells. Biochem Biophys Res Commun 2024; 706:149748. [PMID: 38460450 DOI: 10.1016/j.bbrc.2024.149748] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2023] [Revised: 02/15/2024] [Accepted: 03/04/2024] [Indexed: 03/11/2024]
Abstract
Angiogenesis is a process that is controlled by a delicate combination of proangiogenic and antiangiogenic molecules and can be disrupted in various illnesses, including cancer. Non-cancerous diseases can also have an abnormal or insufficient vascular growth, inflammation and hypoxia, which exacerbate angiogenesis. These conditions include atherosclerosis, psoriasis, endometriosis, asthma, obesity and AIDS. Based on that, the present work assessed the in vitro and ex vivo antiangiogenic properties stemming from BthMP, a P-I metalloproteinase from Bothrops moojeni snake venom, via the VEGF pathway. BthMP at a concentration of 5 and 40 μg/mL showed no toxicity to endothelial cells (HUVEC) in the MTT assay and was not able to induce necrosis and colony proliferation. Interestingly, BthMP inhibited adhesion, migration and invasion of HUVECs in Matrigel and arrested in vitro angiogenesis by reducing the average number of nodules in toxin-treated cells by 9.6 and 17.32 at 5 and 40 μg/mL, respectively, and the number of tubules by 15.9 at 5 μg/mL and 21.6 at 40 μg/mL in a VEGF-dependent way, an essential proangiogenic property. Furthermore, BthMP inhibited the occurrence of the angiogenic process in an ex vivo aortic ring test by decreasing new vessel formation by 52% at 5 μg/mL and by 66% at 40 μg/mL and by increasing the expression of an antiangiogenic gene, SFLT-1, and decreasing the expression of the proangiogenic genes VEGFA and ANGPT-1. Finally, this toxin reduces the production of nitric oxide, a marker that promotes angiogenesis and VEGF modulation, and decreases the protein expression of VEGFA in the supernatant of the HUVEC culture by about 30 %. These results suggest that BthMP has a promising antiangiogenic property and proves to be a biotechnological mechanism for understanding the antiangiogenic responses induced by snake venom metalloproteinases, which could be applied to a variety of diseases that exhibit an imbalance of angiogenesis mechanisms.

Abstract
Cervical squamous cell carcinoma and endocervical adenocarcinoma (CESC) are among the most common malignancies of the female genital tract. Ferroptosis and immunity regulate each other and play important roles in the progression of CESC. The present study aimed to screen ferroptosis- and immune-related differentially expressed genes (FI-DEGs) to identify suitable prognostic signatures for patients with CESC. We downloaded the RNAseq count data and corresponding clinical information of CESC patients from The Cancer Genome Atlas database; obtained recognized ferroptosis- and immune-related genes from the FerrDb and ImmPort databases, respectively; and screened for suitable prognostic signatures using a series of bioinformatics analyses. We identified eight FI-DEGs (CALCRL, CHIT1, DES, DUOX1, FLT1, HELLS, SCD, and SDC1) that were independently correlated with the overall survival of patients with CESC. The prediction model constructed using these eight FI-DEGs was also independently correlated with overall survival. Both the sensitivity and specificity of the prediction model constructed using these eight signatures were over 60%. The comprehensive index of ferroptosis and immune status was significantly correlated with the immunity of patients with CESC. In conclusion, the risk assessment model constructed with these eight FI-DEGs predicted the CESC outcomes. Therefore, these eight FI-DEGs could serve as prognostic signatures for CESC.

Abstract
Glioblastoma multiforme (GBM) is the most prevalent and aggressive form of glioma, with poor prognosis and high mortality rates. As GBM is a highly vascularized cancer, antiangiogenic therapies to halt or minimize the rate of tumor growth are critical to improving treatment. In this review, antiangiogenic therapies, including small-molecule drugs, nucleic acids and proteins and peptides, are discussed. The authors further explore biomaterials that have been utilized to increase the bioavailability and bioactivity of antiangiogenic factors for better antitumor responses in GBM. Finally, the authors summarize the current status of biomaterial-based targeting moieties that target endothelial cells in GBM to more efficiently deliver therapeutics to these cells and avoid off-target cell or organ side effects.

Abstract
AIM We aimed to explore a new approach and theoretical basis for the diagnosis, treatment and prognosis of pre-eclampsia. METHODS In total, 103 pre-eclamptic patients (study group: SG) and 100 healthy pregnant women (control group: CG) were enrolled. Reverse transcription quantitative polymerase chain reaction (RT-qPCR) was used to detect the expression level of serum Hoxb3. Enzyme-linked immunosorbent assay was used to detect the content of serum sFlt-1. Pregnancy outcomes in the two groups were recorded, and the correlations of the levels of Hoxb3 and sFlt-1 with the pregnancy outcomes were analyzed. RESULTS The relative expression of serum Hoxb3 mRNA in the CG was significantly higher than that in the SG, whereas the content of serum sFlt-1 in the CG was significantly lower than that in the SG. Compared with the CG, the SG had a significantly lower number of spontaneous deliveries, higher number of cesarean deliveries and significantly higher number of uneventful perinatal births. The incidences of intrauterine growth restriction, intrauterine distress, premature infants and neonatal deaths in perinatal infants in the SG were significantly higher than those in the CG. According to the analysis of receiver operating characteristic curves, the areas under the curves of Hoxb3, sFlt-1 and their combined detection for diagnosing pre-eclampsia were 0.799, 0.856 and 0.930, respectively. The areas under the curves for predicting poor perinatal outcomes were 0.724, 0.828 and 0.871, respectively. CONCLUSION In conclusion, Hoxb3 and sFlt-1 have certain reference significance for the risk evaluation of pre-eclampsia and the adverse pregnancy outcomes of pre-eclampsia women.

Abstract
AIM This study aimed at evaluating the additional anti-tumor effects of exogenous rVEGFR1 (sFlt1) on conventional chemotherapy in ovarian cancer cell lines. METHODS We utilized cells from two ovarian cancer cell lines, SKOV3 and HeyA8, and treated them with a combination of rVEGFR1 (sFlt1) and carboplatin as well as rVEGFR1 (sFlt1) alone. First, we evaluated cell survival after treatment by using cell counting and MTS assays. Next, we performed Ki67 staining for evaluating the inhibitory effects of the treatment on cell proliferation, and a lactate dehydrogenase (LDH) assay for evaluating cytotoxicity. Finally, to determine whether MAP kinase signaling is involved in this process, we performed western blot analysis of extracellular signal-regulated kinase (ERK), phospho-ERK, c-jun n-terminal kinase (JNK) and phospho-JNK. RESULTS The cytotoxic and growth-restriction effects were more pronounced in the group co-administered with rVEGFR1 (sFlt1) and carboplatin than in cells treated with either rVEGFR1 (sFlt1) or carboplatin alone. Quantitative analysis of Ki67-positive cells also showed a decreased proportion of Ki67-positive cells in SKOV3 cells treated with a combination of exogeneous rVEGFR1 (sFlt1) and carboplatin compared to that in cells treated with either rVEGFR1 (sFlt1) or carboplatin alone. In the LDH assay, we also found significantly enhanced cell toxicity from the combination therapy. Finally, western blotting analysis showed that the MAPK signaling pathway was not affected by sFlt1 treatment. CONCLUSION This study confirmed the additive effects of rVEGFR1 (sFlt1) combined with conventional chemotherapy for ovarian cancer growth in in vitro assays, thus suggesting the combination of rVEGFR1 (sFlt1) and carboplatin as a potential novel therapeutic option for ovarian cancer.
