Transcription factor ZmNAC19 promotes embryo development in Arabidopsis thaliana.

KEY MESSAGE: Overexpression of ZmNAC19, a NAC transcription factor gene from maize, improves embryo development in transgenic Arabidopsis. NAC proteins are plant-specific transcription factors that are involved in multiple aspects of plant growth, development and stress response. Although functions of many NAC transcription factors have been elucidated, little is known about their roles in seed development. In this study, we report the function of a maize NAC transcription factor ZmNAC19 in seed development. ZmNAC19 is highly expressed in embryos of developing maize seeds. ZmNAC19 localizes to nucleus and exhibits transactivation activity in yeast cells. Overexpression of ZmNAC19 in Arabidopsis significantly increases seed size and seed yield. During 3 to 7 days after flowering, embryos of ZmNAC19-overexpression Arabidopsis lines developed faster compared to Col-0, while no visible differences were detected for their endosperms. Furthermore, overexpression of ZmNAC19 in Arabidopsis leads to increased transcription levels of two embryo development-related genes YUC1 and RGE1, and several elements proven to be binding sites of NAC transcription factors were observed in promoters of these two genes. Taken together, these results suggest that ZmNAC19 acts as a positive regulator in plant embryo development.

Electronic Structure Modulation of Nickel Sites by Cationic Heterostructures to Optimize Ethanol Electrooxidation Activity in Alkaline Solution.

It is a good idea for efficient production of hydrogen to use ethanol oxidation reaction (EOR) in place of oxygen evolution reaction (OER) in water electrolysis process. Ni-based non-precious electrocatalysts are widely used in the conversion of ethanol to acetic acid. Here, different selenide heterostructures (NiCoSe, NiFeSe, and NiCuSe) are prepared in which Ni sites are regulated by transition metal. The valence state of Ni is NiCuSe < NiCoSe < NiFeSe in the three heterojunctions. NiCoSe shows the optimized charge distribution of Ni sites and outstanding catalytic activity. The effective modulations lead to optimized d-band center and facilitates both adsorption and desorption of reaction intermediates, which improves the kinetics of EOR. The results of this work prove that with appropriate designed catalyst it is possible to replace kinetically slow OER with faster EOR in water electrolysis to produce hydrogen.

The analysis of HPV integration sites based on nanopore sequencing and the profiling changes along the course of photodynamic therapy.

OBJECTIVE: To detect the HPV genotype and integration sites in patients with high-risk HPV infection at different stages of photodynamic therapy using nanopore technology and to evaluate the treatment effect. METHODS: Four patients with HPV infection were selected and subjected to photodynamic therapy, and cervical exfoliated cell was sampled at before treatment, after three courses of treatment and six courses of treatment, their viral abundance and insertion sites were analyzed by nanopore technology, and pathological examinations were performed before and after treatment. In this study, we developed a novel assay that combined viral sequence enrichment and Nanopore sequencing for identification of HPV genotype and integration sites at once. The assay has obvious advantages over qPCR or NGS-based methods, as it has better sensitivity after viral sequences enrichment and can generate long-reads (kb to Mb) for better detection rate of structure variations, moreover, fast turn-around time for real-time viral sequencing and analysis. RESULTS: The pathological grade was reduced in all four patients after photodynamic therapy. Virus has been cleared in two cases after treatment, the virus amount reduced after treatment but not completely cleared in one case, and two type viruses were cleared and one type virus persisted after treatment in the last patient with multiple infection. Viral abundance and the number of integration sites were positively correlated. Gene enrichment analysis showed complete viral clearance in 1 patient and 3 patients required follow-up. CONCLUSION: Nanopore sequencing can effectively monitor the abundance of HPV viruses and integration sites to show the presence status of viruses, and combined with the results of gene enrichment analysis, the treatment effect can be dynamically assessed.

Atomic reconstruction and oxygen adsorption behavior of the pyrite (100) surface: a DFT study.

The analysis of the surface chemical behavior of pyrite is highly crucial in the fields of environmental conservation, metal extraction, and flotation separation. In this paper, the mechanism of atomic reconstruction on the pyrite surface and the adsorption behavior of O2 on a reconstructed surface are calculated by density functional theory (DFT). Different reconstruction surfaces were constructed by deleting S and Fe atoms on the (100) surface of pyrite. In addition, the geometric configuration, formation energy, binding energy, cohesion energy, and surface electronic properties of the reconstruction surface were calculated. The adsorption energies and geometric configurations of O2 on different reconstructed surfaces were also determined. The results show that under Fe-poor conditions, the charge of Fe atoms increases, and S atoms form Sn on the reconstructed surface. The binding energy between the Sn and the substrate (ideal surface) is lower, which is similar to the Sn adsorption on the substrate surface with the Fe atom as the site. Sn has high cohesive energy and is resistant to being attacked by oxidants, which leads to structural collapse, and a low affinity for O2. Under S-poor conditions, the -[Fe-S]n- plane structure formed on the reconstructed surface. The -[Fe-S]n- structure stably bonds to the substrate by an Fe-S bond, and exhibits strong binding energy. However, the -[Fe-S]n- structure has low cohesive energy and exhibits thermodynamic instability. In contrast, O2 shows a strong affinity for the -[Fe-S]n- structure, indicating that the deficiency of the S atom promotes the surface oxidation reaction. The mechanism of atomic reconstruction on the surface of pyrite is of utmost importance for understanding its surface chemical behavior.

First principles study of structural and electron properties in scorodite: the bulk and surface.

Scorodite (FeAsO4·2H2O) is an ideal material for the fixation of arsenic that has attracted considerable research interest in recent decades. However, the position of the H atom in the scorodite crystal structure, water molecular configuration, surface morphology, and chemical state of the surface atoms have not been reported. In this work, density functional theory (DFT) is used to optimize the scorodite crystal structure, and the atomic bonding is analyzed. At the same time, a surface model is constructed to calculate the configuration and electronic structure of the surface atoms for different coordination groups. The results show that the tetrahedral [AsO4] and octahedral [FeO4(2H2O)] groups in the scorodite crystal structure have good stability(geometry configuration), and the covalent bond strength between the As atom and the bridged oxygen atom (Ob) is greater than that between the Ob atom and the Fe atom. The water molecules in the crystal structure do not seriously deform and ionize. The configuration of the water molecules remains stable through electrostatic interactions (Ow-Fe) and hydrogen bonding (H-Ob). The Fe atoms on the surface of scorodite can coordinate with OH and H2O, while the As atoms can only form a stable coordination with OH. When an Fe atom on the surface coordinates with two H2O atoms, the Fe atom will shrink to the inside of the bulk. With the increase in the hydroxylation number of the Fe atom, the bonding strength between the Fe atom and the Ob atom decreases. Different surface configurations do not affect the stability(geometry configuration) of the [AsO4] structure. In addition, the surface water molecular layer has a very weak effect on the surface coordination configuration. By contrast, in the surface configuration of the (W + OH) structure, the change in the surface atomic layer spacing is the smallest.

Peroxymonosulfate activation by Fe-N-S co-doped tremella-like carbocatalyst for degradation of bisphenol A: Synergistic effect of pyridine N, Fe-Nx, thiophene S.

Bisphenol A (BPA) has received increasing attention due to its long-term industrial application and persistence in environmental pollution. Iron-based carbon catalyst activation of peroxymonosulfate (PMS) shows a good prospect for effective elimination of recalcitrant contaminants in water. Herein, considering the problem about the leaching of iron ions and the optimization of heteroatoms doping, the iron, nitrogen and sulfur co-doped tremella-like carbon catalyst (Fe-NS@C) was rationally designed using very little iron, S-C3N4 and low-cost chitosan (CS) via the impregnation-calcination method. The as-prepared Fe-NS@C exhibited excellent performance for complete removal of BPA (20 mg/L) by activating PMS with the high kinetic constant (1.492 min-1) in 15 min. Besides, the Fe-NS@C/PMS system not only possessed wide pH adaptation and high resistance to environmental interference, but also maintained an excellent degradation efficiency on different pollutants. Impressively, increased S-C3N4 doping amount modulated the contents of different N species in Fe-NS@C, and the catalytic activity of Fe-NS@C-1-x was visibly enhanced with increasing S-C3N4 contents, verifying pyridine N and Fe-Nx as main active sites in the system. Meanwhile, thiophene sulfur (C-S-C) as active sites played an auxiliary role. Furthermore, quenching experiment, EPR analysis and electrochemical test proved that surface-bound radicals (·OH and SO4⋅-) and non-radical pathways worked in the BPA degradation (the former played a dominant role). Finally, possible BPA degradation route were proposed. This work provided a promising way to synthesize the novel Fe, N and S co-doping carbon catalyst for degrading organic pollutants with low metal leaching and high catalytic ability.

EMP80 mediates the C-to-U editing of nad7 and atp4 and interacts with ZmDYW2 in maize mitochondria.

RNA C-to-U editing is important to the expression and function of organellar genes in plants. Although several families of proteins have been identified to participate in this process, the underlying mechanism is not fully understood. Here we report the function of EMP80 in the C-to-U editing at the nad7-769 and atp4-118 sites, and the potential recruitment of ZmDYW2 as a trans deaminase in maize (Zea mays) mitochondria. Loss of EMP80 function arrests embryogenesis and endosperm development in maize. EMP80 is a PPR-E+ protein localised to mitochondria. An absence of EMP80 abolishes the C-to-U RNA editing at nad7-769 and atp4-118 sites, resulting in a cysteine-to-arginine (Cys→Arg) change in Nad7 and Atp4 in the emp80 mutant. The amino acid change consequently reduces the assembly of complexes I and V, leading to an accumulation of the F1 subcomplex of complex V. EMP80 was found to interact with atypical DYW-type PPR protein ZmDYW2, which interacts with ZmNUWA. Co-expression of ZmNUWA enhances the interaction between EMP80 and ZmDYW2, suggesting that EMP80 potentially recruits ZmDYW2 as a trans deaminase through protein-protein interaction, and ZmNUWA may function as an enhancer of this interaction.

A deep learning approach to automate whole-genome prediction of diverse epigenomic modifications in plants.

Epigenetic modifications function in gene transcription, RNA metabolism, and other biological processes. However, multiple factors currently limit the scientific utility of epigenomic datasets generated for plants. Here, using deep-learning approaches, we developed a Smart Model for Epigenetics in Plants (SMEP) to predict six types of epigenomic modifications: DNA 5-methylcytosine (5mC) and N6-methyladenosine (6mA) methylation, RNA N6-methyladenosine (m6 A) methylation, and three types of histone modification. Using the datasets from the japonica rice Nipponbare, SMEP achieved 95% prediction accuracy for 6mA, and also achieved around 80% for 5mC, m6 A, and the three types of histone modification based on the 10-fold cross-validation. Additionally, > 95% of the 6mA peaks detected after a heat-shock treatment were predicted. We also successfully applied the SMEP for examining epigenomic modifications in indica rice 93-11 and even the B73 maize line. Taken together, we show that the deep-learning-enabled SMEP can reliably mine epigenomic datasets from diverse plants to yield actionable insights about epigenomic sites. Thus, our work opens new avenues for the application of predictive tools to facilitate functional research, and will almost certainly increase the efficiency of genome engineering efforts.

Functions of PPR Proteins in Plant Growth and Development.

Pentatricopeptide repeat (PPR) proteins form a large protein family in land plants, with hundreds of different members in angiosperms. In the last decade, a number of studies have shown that PPR proteins are sequence-specific RNA-binding proteins involved in multiple aspects of plant organellar RNA processing, and perform numerous functions in plants throughout their life cycle. Recently, computational and structural studies have provided new insights into the working mechanisms of PPR proteins in RNA recognition and cytidine deamination. In this review, we summarized the research progress on the functions of PPR proteins in plant growth and development, with a particular focus on their effects on cytoplasmic male sterility, stress responses, and seed development. We also documented the molecular mechanisms of PPR proteins in mediating RNA processing in plant mitochondria and chloroplasts.

EMP18 functions in mitochondrial atp6 and cox2 transcript editing and is essential to seed development in maize.

RNA editing plays an important role in organellar gene expression in plants, and pentatricopeptide repeat (PPR) proteins are involved in this function. Because of its large family size, many PPR proteins are not known for their function and roles in plant growth and development. Through genetic and molecular analyses of the empty pericarp18 (emp18) mutant in maize (Zea mays), we cloned the Emp18 gene, revealed its molecular function, and defined its role in the mitochondrial complex assembly and seed development. Emp18 encodes a mitochondrial-localized DYW-PPR protein. Null mutation of Emp18 arrests embryo and endosperm development at an early stage in maize, resulting in embryo lethality. Mutants are deficient in the cytidine (C)-to-uridine (U) editing at atp6-635 and cox2-449, which converts a Leu to Pro in ATP6 and a Met to Thr in Cox2. The atp6 gene encodes the subunit a of F1 Fo -ATPase. The Leu to Pro alteration disrupts an α-helix of subunit a, resulting in a dramatic reduction in assembly and activity of F1 Fo -ATPase holoenzyme and an accumulation of free F1 -subcomplex. These results demonstrate that EMP18 functions in the C-to-U editing of atp6 and cox2, and is essential to mitochondrial biogenesis and seed development in maize.

Benzylarylation of N-Allyl Anilines: Synthesis of Benzylated Indolines.

An unprecedented benzylic C-H functionalization of methyl arenes across unactivated alkenes is presented. In the presence of MnCl2·4H2O and di- tert-butyl peroxide, N-allyl anilines underwent benzylation/cyclization cascade to give benzylated indolines, which are a previously unmet synthetic goal. This protocol features simple operation, broad substrate scope, and great exo selectivity.

[Effect of different feeding initiation formulas on very low birth weight infants].

OBJECTIVE: To explore the effect of feeding initiation with different formulas on the growth, development, and feeding tolerance in very low birth weight infants. METHODS: A total of 86 preterm infants with a gestational age of <34 weeks and a birth weight of <1 500 g were divided into three groups according to their feeding initiation formulas: standard preterm formula feeding group (SPF group; n=31), extensively hydrolyzed protein formula feeding group (eHF group; n=27), and breastfeeding group (control group; n=28). Comparisons were made between the groups in terms of growth indices, feeding condition, blood biochemistry, length of hospital stay, and incidence rates of feeding intolerance, sepsis, necrotizing enterocolitis (NEC), and extrauterine growth retardation (EUGR). RESULTS: There were no significant differences among the above three groups in body weight, head circumference, and rate of increase in body length measured during hospitalization, as well as length of hospital stay and EUGR incidence rate at discharge (P>0.05). The SPF and eHF groups had a significantly shorter transition time from meconium to yellow stool than the control group (P<0.01). The SPF group had a significantly shorter time to standard enteral feeding than the eHF and control groups (P<0.01), with no significant difference observed between the latter two groups. The SPF group had a significantly lower serum prealbumin level than the eHF and control groups (P<0.01). The SPF and eHF groups had a significantly higher hemoglobin level at discharge than the control group (P<0.01). The percentage of eosinophils at discharge was significantly lower in the eHF group than in the SPF group (P<0.01). No significant differences were found among the three groups regarding the incidence rates of feeding intolerance, sepsis, and NEC (P>0.05). CONCLUSIONS: Both eHF and SPF can be used for feeding initiation for very low birth weight preterm infants with a gestational age of <34 weeks without increasing the incidence rate of EUGR.

A low-temperature-responsive element involved in the regulation of the Arabidopsis thaliana At1g71850/At1g71860 divergent gene pair.

KEY MESSAGE: The bidirectional promoter of the Arabidopsis thaliana gene pair At1g71850/At1g71860 harbors low-temperature-responsive elements, which participate in anti-correlated transcription regulation of the driving genes in response to environmental low temperature. A divergent gene pair is defined as two adjacent genes organized head to head in opposite orientation, sharing a common promoter region. Divergent gene pairs are mainly coexpressed, but some display opposite regulation. The mechanistic basis of such anti-correlated regulation is not well understood. Here, the regulation of the Arabidopsis thaliana gene pair At1g71850/At1g71860 was investigated. Semi-quantitative RT-PCR and Genevestigator analyses showed that while one of the pair was upregulated by exposure to low temperature, the same treatment downregulated the other. Promoter::GUS fusion transgenes were used to show that this behavior was driven by a bidirectional promoter, which harbored an as-1 motif, associated with the low-temperature response; mutation of this sequence produced a significant decrease in cold-responsive expression. With regard to the as-1 motif in the native orientation repressing the promoter's low-temperature responsiveness, the same as-1 motif introduced in the reverse direction showed a slight enhancement in the promoter's responsiveness to low-temperature exposure, indicating that the orientation of the motif was important for the promoter's activity. These findings provide new insights into the complex transcriptional regulation of bidirectional gene pairs as well as plant stress response.

Efficacy and safety of endometrial ablation for treating abnormal uterine bleeding in pre- and postmenopausal women with liver cirrhosis.

AIM: Abnormal uterine bleeding (AUB) occurs in 10-30% of women of reproductive age and up to 61% of cirrhotic women. We evaluated the efficacy and safety of endometrial ablation (NovaSure therapy) for AUB in cirrhotic women. METHODS: This prospective, two-arm, observational study enrolled patients for NovaSure treatment, and they were followed for 12 months. Primary measurements were the amenorrhea rate and changes of pictorial blood loss assessment chart (PBLAC) scores at 1-month post-therapy. Key secondary end-points included the longevity of amenorrhea at 12 months, safety profile, and progression of cirrhosis. RESULTS: Among 88 women, 26 were cirrhotic and 62 were non-cirrhotic. At 1-month post-NovaSure treatment, a significant reduction of mean PBLAC scores was observed in cirrhotic patients compared to those at baseline (0.4 ± 1.3 vs 215.2 ± 410.9, P < 0.001), and the amenorrhea rate was 88.5%. The efficacy outcomes of the PBLAC scores and amenorrhea rate were maintained until the end of the 12-month follow-up. A significant improvement in quality of life scores was observed 1-month post-therapy compared to those at baseline (5.4 ± 3.1 vs 20.5 ± 5.5, P < 0.001). Patients' satisfaction rates were 100% and 92.31% at 6 and 12 months, respectively. The aforementioned outcomes were comparable with those in non-cirrhotic patients. No significant progression of cirrhosis or safety concern was reported. CONCLUSION: Cirrhotic patients on NovaSure therapy had a high rate of amenorrhea 1-month post-treatment, which maintained longevity for 12 months. The safety profile was similar to that in non-cirrhotic patients.

[Advance in molecular genetic research on primary congenital glaucoma].

Primary congenital glaucoma (PCG) is one of the major diseases causing blindness in children, but its pathogenesis has remained unclear. Genetic factors play an important role in the pathogenesis of PCG. Molecular genetics of candidate genes such as CYP1B1, MYOC, LTBP2 and FOXC1 has so far been explored, but no disease-causing gene has been identified. Molecular genetic research on PCG including candidate gene screening and research strategies are reviewed here.

Genetic associations in PLEKHA7 and COL11A1 with primary angle closure glaucoma: a meta-analysis.

BACKGROUND: Single nucleotide polymorphisms (SNPs) rs11024102 in PLEKHA7 and rs3753841 in COL11A1 were identified to be associated with primary angle closure glaucoma (PACG) by a recent large genome-wide association study. This present study is to evaluate the association of PLEKHA7 rs11024102 and COL11A1 rs3753841 with PACG. DESIGN: A systematic review and meta-analysis. PARTICIPANTS: A total of 25 271 subjects (4895 PACG patients and 20 376 controls) in different ethnicities were tested for PLEKHA7 rs11024102 and COL11A1 rs3753841. METHODS: A comprehensive literature search was conducted on studies published up to July 2014. Summary odds ratios (ORs) and 95% confidence intervals were analysed. Publication bias of the included articles was evaluated using funnel plots and Egger's test. MAIN OUTCOME MEASURES: OR for the effects of PLEKHA7 rs11024102 and COL11A1 rs3753841 on PACG risk. RESULTS: Four eligible articles were included in this study for meta-analysis. The overall result showed that SNPs rs11024102 and rs3753841 were statistically associated with PACG (P < 0.001) in fixed-effects model. Stratified analyses showed that the association of PLEKHA7 rs11024102 and COL11A1 rs3753841 with PACG was statistically significant in Asian population (including South Indian cohort) (P < 0.001). In Caucasian population, significant association of COL11A1 rs3753841 with PACG was detected (P = 0.004), but PLEKHA7 rs11024102 did not show any association with PACG (P = 0.140). CONCLUSIONS: This meta-analysis suggests that PLEKHA7 rs11024102 is associated with PACG in Asian population and COL11A1 rs3753841 has a genetic association with the development of PACG both in Caucasian and Asian populations.

[Association between LOXL1 gene polymorphisms and primary open angle glaucoma in Sichuan population].

OBJECTIVE: To investigate association between the lysyl oxidase-like 1 (LOXL1) gene single nucleotide polymorphism (SNP) and primary open-angle glaucoma (POAG) in Sichuan population. METHODS: In this study,416 subjects with primary open-angle glaucoma and 997 normal controls were recruited.Three reported LOXL1 tag SNPs (rs1048661,rs3825942 and rs2165241) were genotyped by SNaPshot method. RESULTS: The study showed that the genotypes of LOXL1 rs1048661,rs3825942 and rs2165241 between POAG and control groups were not statistically significant (OR=1.085, 95%CI 0.92-1.28, P=0.578 for rs1048661; OR=1.059, 95%CI 0.82-1.37, P=0.846 for rs3825942; OR=1.006, 95%CI 0.77-1.32, P=0.966 for rs2165241, respectively). There were no significant difference in allele frequency distribution of LOXL1 rs1048661、rs3825942 and rs2165241 between POAG and normal controls (P=0.322, P=0.660, P=0.965). CONCLUSION: The results from the present study do not indicate the association of LOXL1 SNPs (rs1048661, rs3825942 and rs2165241) with POAG in Sichuan population.

Research Progress of Group II Intron Splicing Factors in Land Plant Mitochondria.

Mitochondria are important organelles that provide energy for the life of cells. Group II introns are usually found in the mitochondrial genes of land plants. Correct splicing of group II introns is critical to mitochondrial gene expression, mitochondrial biological function, and plant growth and development. Ancestral group II introns are self-splicing ribozymes that can catalyze their own removal from pre-RNAs, while group II introns in land plant mitochondria went through degenerations in RNA structures, and thus they lost the ability to self-splice. Instead, splicing of these introns in the mitochondria of land plants is promoted by nuclear- and mitochondrial-encoded proteins. Many proteins involved in mitochondrial group II intron splicing have been characterized in land plants to date. Here, we present a summary of research progress on mitochondrial group II intron splicing in land plants, with a major focus on protein splicing factors and their probable functions on the splicing of mitochondrial group II introns.

Orbital Occupancy Modulation to Optimize Intermediate Absorption for Efficient Electrocatalysts in Water Electrolysis and Zinc-Ethanol-Air Battery.

Spin engineering is a promising way to modulate the interaction between the metal d-orbital and the intermediates and thus enhance the catalytic kinetics. Herein, an innovative strategy is reported to modulate the spin state of Co by regulating its coordinating environment. o-c-CoSe2-Ni is prepared as pre-catalyst, then in situ electrochemical impedance spectroscopy (EIS) and in situ Raman spectroscopy are employed to prove phase transition, and CoOOH/Co3O4 is formed on the surface as active sites. In hybrid water electrolysis, the voltage has a negative shift, and in zinc-ethanol-air battery, the charging voltage is lowered and the cycling stability is greatly increased. Coordinated atom substitution and crystalline symmetry change are combined to regulate the absorption ability of reaction intermediates with balanced optimal adsorption. Coordinated atom substitution weakens the adsorption while the crystalline symmetry change strengthens the adsorption. Importantly, the tetrahedral sites are introduced by Ni doping which enables the co-existence of four-coordinated sites and six-coordination sites in o-c-CoSe2-Ni. The dz2 + dx2-y2 orbital occupancy decreases after the atomic substitution, while increases after replacing the CoSe6-Oh field with CoSe6-Oh/CoSe4-Td. This work explores a new direction for the preparation of efficient catalysts for water electrolysis and innovative zinc-ethanol-air battery.

Dynamics of endothelial cells migration in nature-mimicking blood vessels.

Endothelial cells (ECs) migration is a crucial early step in vascular repair and tissue neovascularization. While extensive research has elucidated the biochemical drivers of endothelial motility, the impact of biophysical cues, including vessel geometry and topography, remains unclear. Herein, we present a novel approach to reconstruct 3D self-assembly blood vessels-on-a-chip that accurately replicates real vessel geometry and topography, surpassing conventional 2D flat tube formation models. This vessels-on-a-chip system enables real-time monitoring of vasculogenesis and ECs migration at high spatiotemporal resolution. Our findings reveal that ECs exhibit increased migration speed and directionality in response to narrower vessel geometries, transitioning from a rounded to a polarized morphology. These observations underscore the critical influence of vessel size in regulating ECs migration and morphology. Overall, our study highlights the importance of biophysical factors in shaping ECs behavior, emphasizing the need to consider such factors in future studies of endothelial function and vessel biology.
