A soybean bZIP transcription factor is involved in submergence resistance.

Although the functions of basic leucine zipper (bZIP) family transcription factors in the regulation of various abiotic stresses are beginning to be unveiled, the precise roles of bZIP proteins in plants coping with submergence stress remain unclear. Here we identified a bZIP gene GmbZIP71-4 from soybean, which localized in the nucleus. The GmbZIP71-4 over-expressed tabocco line showed reduced submergence resistance due to the decreased abscisic acid (ABA) content. GO and KEGG pathway analysis based on chromatin immunoprecipitation assay sequencing (ChIP-seq) indicated that the differences expressed genes between submergence treatment and control groups were specially enriched in plant hormone signal transduction items, especially those in response to ABA. Electrophoretic mobility shift assays (EMSA) demonstrated that GmbZIP71-4 bound to the promoter of GmABF2 gene, which is consistent with the ChIP-qPCR results. GmbZIP71-4 function as a negative regulator of soybean in responding to submergence stress through manipulating ABA signaling pathway. This findings will set a solid foundation for the understanding of submergence resistance in plants.

Automatic Vertebral Rotation Angle Measurement of 3D Vertebrae Based on an Improved Transformer Network.

The measurement of vertebral rotation angles serves as a crucial parameter in spinal assessments, particularly in understanding conditions such as idiopathic scoliosis. Historically, these angles were calculated from 2D CT images. However, such 2D techniques fail to comprehensively capture the intricate three-dimensional deformities inherent in spinal curvatures. To overcome the limitations of manual measurements and 2D imaging, we introduce an entirely automated approach for quantifying vertebral rotation angles using a three-dimensional vertebral model. Our method involves refining a point cloud segmentation network based on a transformer architecture. This enhanced network segments the three-dimensional vertebral point cloud, allowing for accurate measurement of vertebral rotation angles. In contrast to conventional network methodologies, our approach exhibits notable improvements in segmenting vertebral datasets. To validate our approach, we compare our automated measurements with angles derived from prevalent manual labeling techniques. The analysis, conducted through Bland-Altman plots and the corresponding intraclass correlation coefficient results, indicates significant agreement between our automated measurement method and manual measurements. The observed high intraclass correlation coefficients (ranging from 0.980 to 0.993) further underscore the reliability of our automated measurement process. Consequently, our proposed method demonstrates substantial potential for clinical applications, showcasing its capacity to provide accurate and efficient vertebral rotation angle measurements.

Bioinspired Total Synthesis of Complex Nucleoside Antibiotics A201A, A201D and A201E.

Herein, bioinspired total syntheses of A201A, A201D, and A201E based on a previously reported biosynthetic pathway are presented. The challenging 1,2-cis-furanoside, a core structure of the A201 family, was obtained by remote 2-quinolinecarbonyl-assisted glycosylation. We accomplished the total synthesis of A201A and A201E based on the critical 1,2-cis-furanoside moiety through late-stage glycosylation without any interference from basic dimethyl adenosine. We also confirmed the absolute configuration of A201E by total synthesis. This modular synthesis strategy enables efficient preparation of A201 family antibiotics, allowing the study of their structure-activity relationships and mode of action. This study satisfies the increasing demand for developing novel antibiotics inspired by the A201 family.

Infrared and Visible Image Fusion with Significant Target Enhancement.

Existing fusion rules focus on retaining detailed information in the source image, but as the thermal radiation information in infrared images is mainly characterized by pixel intensity, these fusion rules are likely to result in reduced saliency of the target in the fused image. To address this problem, we propose an infrared and visible image fusion model based on significant target enhancement, aiming to inject thermal targets from infrared images into visible images to enhance target saliency while retaining important details in visible images. First, the source image is decomposed with multi-level Gaussian curvature filtering to obtain background information with high spatial resolution. Second, the large-scale layers are fused using ResNet50 and maximizing weights based on the average operator to improve detail retention. Finally, the base layers are fused by incorporating a new salient target detection method. The subjective and objective experimental results on TNO and MSRS datasets demonstrate that our method achieves better results compared to other traditional and deep learning-based methods.

Involvement of TCF7L2 in generation of morphine-induced antinociceptive tolerance and hyperalgesia by modulating TLR4/ NF-κB/NLRP3 in microglia.

Morphine is an opioid agonist and a nonselective mu, kappa and delta receptor agonist. It is a commonly used analgesic drug for the treatment of acute and chronic pain as well as cancer pain. Morphine is particularly important to address the problem of morphine tolerance. Tcf7l2, known as a risk gene for schizophrenia and autism, encodes a member of the LEF1/TCF transcription factor family. TCF7L2 is an important transcription factor that is upregulated in neuropathic pain models. However, the relationship between TCF7L2 and morphine tolerance has not been reported. In this study, we found that morphine tolerance led to the upregulation of TCF7L2 in the spinal cord, and also led to the upregulation of TCF7L2 expression in glial cells, which promoted inflammation related signal, and activated TLR4 / NF-κB/NLRP3 pathway. In addition, TCF7L2 regulated microglial cell activation induced by chronic morphine treatment. Mechanically, we found that TCF7L2 transcriptionally regulated TLR4 expression, and the depletion of TCF7L2 alleviated morphine tolerance induced by chronic morphine treatment, and further alleviated pain hypersensitivity induced by chronic morphine treatment. We therefore suggested that TCF7L2 regulates the activation of TLR4/ NF-κB/NLRP3 pathway in microglia, and is involved in the formation of morphine tolerance. Our results provide a new idea for the regulation mechanism of morphine tolerance.

Mutant selection window of clarithromycin for clinical isolates of Helicobacter pylori.

BACKGROUND: Clarithromycin-resistance is becoming a global health concern in the treatment of Helicobacter pylori (H. pylori). The mutant prevention concentration (MPC) represent the propensities of antimicrobial agents to select resistant mutants. The concentration range between the minimum inhibitory concentration (MIC) and the MPC is defined as mutant selection window (MSW). In this study, we aimed to determine the cause of increasing clarithromycin resistance by investigating the MSW for clinical isolates of H. pylori. RESULTS: A retrospective subgroup, which included 68 clarithromycin-sensitive H. pylori strains, was selected from a double-blind trial. The MICs and MPCs were determined using agar plate assays. Genotypic tests were performed using Sanger sequencing. All isolates were wild-type, and 33.82% (23/68) had a 0.016 mg/L MIC, 45.59% (31/68) had a 0.031 mg/L MIC, 16.18% (11/68) had a 0.062 ≤ MIC ≤ 0.125 mg/L, and 4.41% (3/68) had a 0.25 mg/L MIC. The MPC50/90 (mg/L) of the isolates were: 0.062/0.125, 0.125/0.5, 0.25/0.25 and 1/2, respectively. The MPCs showed a moderate correlation with the MICs (rs = 0.65, P < 0.0001). Using published data and MPC90, we calculated the time inside the MSW (TMSW) for low- and high-dose (200 or 500 mg bid) clarithromycin that were 6 and 0 h, 24 and 4 h, 15 and 2 h, 5 and 17 h for the strains with MICs (mg/L) of 0.016, 0.031, 0.062-0.125, and 0.25, respectively. CONCLUSIONS: This study showed that in the clarithromycin-sensitive clinical isolates of H. pylori, low-dose clarithromycin may lead to decreased drug sensitivity or even clarithromycin resistance; strains with a 0.25 mg/L MIC display a high risk of treatment failure.

New method to estimate surface upwelling long-wave radiation from MODIS cloud-free data.

As an important component in the surface radiation budget, surface upwelling longwave radiation (SULR) is an outcome of the land surface energy exchange and mainly represents the capability of thermal radiation from the surface of the Earth. Existing satellite-derived SULR products are too coarse to support high-resolution numerical models, and their accuracy needs to be improved. In this study, an equivalent temperature is introduced through which a "split-window" atmospheric correction algorithm is developed for MODIS data to estimate the instantaneous clear-sky SULR. It is a simple and feasible method that is particularly applicable to MODIS data to acquire relatively high precision SULR under clear skies from which qualified water vapor contents (WVC) and thermal channel brightness temperatures are available. The root mean square errors (RMSEs) are less than 13 W/m2 for all WVC sub-ranges with the viewing zenith angle (VZA) less than 30°, or for all sub-ranges with the VZA less than 60° and the WVC less than 3.5 g/cm2. Also, applications and comparisons with the LST-emissivity method are made by using ground measurements which are collected from the network of surface radiation budget network data (SURFRAD) at the moment of MODIS overpass. Results show that the proposed model has high computational efficiency to estimate SULR from MODIS cloud-free data.

Ligand-Promoted Meta-C-H Arylation of Anilines, Phenols, and Heterocycles.

Here we report the development of a versatile 3-acetylamino-2-hydroxypyridine class of ligands that promote meta-C-H arylation of anilines, heterocyclic aromatic amines, phenols, and 2-benzyl heterocycles using norbornene as a transient mediator. More than 120 examples are presented, demonstrating this ligand scaffold enables a wide substrate and coupling partner scope. Meta-C-H arylation with heterocyclic aryl iodides as coupling partners is also realized for the first time using this ligand. The utility for this transformation for drug discovery is showcased by allowing the meta-C-H arylation of a lenalidomide derivative. The first steps toward a silver-free protocol for this reaction are also demonstrated.

Retrieving Land Surface Temperature from Hyperspectral Thermal Infrared Data Using a Multi-Channel Method.

Land Surface Temperature (LST) is a key parameter in climate systems. The methods for retrieving LST from hyperspectral thermal infrared data either require accurate atmospheric profile data or require thousands of continuous channels. We aim to retrieve LST for natural land surfaces from hyperspectral thermal infrared data using an adapted multi-channel method taking Land Surface Emissivity (LSE) properly into consideration. In the adapted method, LST can be retrieved by a linear function of 36 brightness temperatures at Top of Atmosphere (TOA) using channels where LSE has high values. We evaluated the adapted method using simulation data at nadir and satellite data near nadir. The Root Mean Square Error (RMSE) of the LST retrieved from the simulation data is 0.90 K. Compared with an LST product from the Spinning Enhanced Visible and Infrared Imager (SEVIRI) on Meteosat, the error in the LST retrieved from the Infared Atmospheric Sounding Interferometer (IASI) is approximately 1.6 K. The adapted method can be used for the near-real-time production of an LST product and to provide the physical method to simultaneously retrieve atmospheric profiles, LST, and LSE with a first-guess LST value. The limitations of the adapted method are that it requires the minimum LSE in the spectral interval of 800-950 cm(-1) larger than 0.95 and it has not been extended for off-nadir measurements.

Metal-Free Difunctionalization of Alkynes with 2-Chlorodithiane for Synthesis of ß-Ketodithianes.

Dithianes are versatile umpolung intermediates in organic synthesis but have rarely been employed in radical cross-coupling reactions. Here we describe the oxidative coupling method for alkyne difunctionalization under metal-catalyst-free conditions. The efficient protocol directly affords a variety of ß-ketodithianes in good to excellent yields with high regioselectivities. It provides a general pathway for accessing valuable dithianes with controlled formation of a new C-C bond and a C-O bond via a radical coupling pathway.

Role of continuous high thoracic epidural anesthesia in hippocampal apoptosis after global cerebral ischemia in rats.

BACKGROUND: Cervical sympathetic blockade has been found to reduce cerebral vascular resistance and improve focal cerebral ischemia/reperfusion injury. In this study, we tested the hypothesis that the sympathetic blockade of high thoracic epidural anesthesia (HTEA) would reduce hippocampal apoptosis after global cerebral ischemia (GCI) injury. METHODS: Fifteen-minute global ischemia was established by 4-vessel occlusion in adult male Wistar rats. And 0.5% bupivacaine or 0.9% saline (20 µl//h) was infused continuously to the thoracic epidural space through the T4-5 intervertebral space from 15 minutes before ischemia to 24 hours or 72 hours after ischemia. Cerebral blood flow (CBF), Mortality, neurodeficit scores (NDS), Nissl and TUNEL staining, hippocampal superoxide dismutase (SOD) activity, malondialdehyde (MDA) concentrations, western blot of poly (ADP-ribose) polymerase (PARP) and immunohistochemical staining (PARP, Bax and Bcl-2) were determined. RESULTS: Both the hyperpefusion and hypoperfusion after reperfusion were improved by HTEA. HTEA decreased the number of apoptotic neurons in cornu ammonis area 1 (CA1), reduced PARP and Bax expressions with a decrease of Bax/Bcl-2 ratio induced by ischemic injury. The upregulation of SOD activity and the downregulation of MDA were obvious in the HTEA group compared with the GCI group. HTEA also improved NDS but not the mortality rate. CONCLUSION: Our study demonstrated that continuous HTEA attenuates hippocampal apoptosis and a behavioral deficit after global cerebral ischemia, and that these protective effects are associated with the improved microcirculation, reduced oxidative stress and the less activation of PARP.

Palladium nanoparticles bonded to two-dimensional iron oxide graphene nanosheets: a synergistic and highly reusable catalyst for the Tsuji-Trost reaction in water and air.

Low cost, high activity and selectivity, convenient separation, and increased reusability are the main requirements for noble-metal-nanocatalyst-catalyzed reactions. Despite tremendous efforts, developing noble-metal nanocatalysts to meet the above requirements remains a significant challenge. Here we present a general strategy for the preparation of strongly coupled Fe(3)O(4) and palladium nanoparticles (PdNPs) to graphene sheets by employing polyethyleneimine as the coupling linker. Transmission electron microscopic images show that Pd and Fe(3)O(4) nanoparticles are highly dispersed on the graphene surface, and the mean particle size of Pd is around 3 nm. This nanocatalyst exhibits synergistic catalysis by Pd nanoparticles supported on reduced graphene oxide (rGO) and a tertiary amine of polyethyleneimine (Pd/Fe(3)O(4)/PEI/rGO) for the Tsuji-Trost reaction in water and air. For example, the reaction of ethyl acetoacetate with allyl ethyl carbonate afforded the allylated product in more than 99 % isolated yield, and the turnover frequency reached 2200 h(-1). The yield of allylated products was 66 % for Pd/rGO without polyethyleneimine. The catalyst could be readily recycled by a magnet and reused more than 30 times without appreciable loss of activity. In addition, only about 7.5 % of Pd species leached off after 20 cycles, thus rendering this catalyst safer for the environment.

Synthesis of the Cyclopentane Core Skeleton of Cranomycin and Jogyamycin.

Cranomycin and jogyamycin, two aminocyclopentitol natural products, possess complex structures and potential medicinal properties. This review describes synthetic studies about the process of making an advanced intermediate of cranomycin and jogyamycin. This highly functionalized intermediate, featuring three contiguous amine-substituted stereocenters, was constructed from cyclopentadiene through a series of reactions including the nitroso Diels-Alder reaction, nitrogen radical cyclization reaction, 1,2-nitrogen migration, and stereoselective nitrogen addition.

Aerobic exercise improves verbal working memory sub-processes in adolescents: behavioral evidence from an N-back task.

Background: Studies on the effects of aerobic exercise on working memory (WM) have mainly concentrated on the overall effects, yet there is little knowledge on how moderate intensity aerobic exercise impacts the sub-processes of verbal WM (VWM) in adolescents. To address this gap, two experiments were conducted to explore the influence of aerobic exercise on the maintenance and updating sub-processes of VWM. Methods: In Experiment 1, a mixed experimental design of 2 (exercise habit: high vs. low) × 3 (memory load: 0-back vs. 1-back vs. 2-back) was used to compare VWM and its sub-processes in 40 adolescents. In Experiment 2, a 2 (group: intervention vs. control) × 3 (time point: pretest vs. 1st post-test vs. 18th post-test) × 3 (memory load: 0-back vs. 1-back vs. 2-back) mixed experimental design was used to investigate the acute and long-term effects of moderate intensity aerobic exercise on VWM and its sub-processes in 24 adolescents with low exercise habits. Results: The results of Experiment 1 showed that VWM performance and its sub-processes in the high exercise habit group were better than those in the low exercise habit group. The results of Experiment 2 showed that the effects of the long-term exercise intervention were superior to those of the acute exercise intervention, and both were superior to the pretest. Meanwhile, it was found that aerobic exercise intervention had a greater effect size on the updating sub-process of VWM. Conclusion: In conclusion, the results indicated that moderate intensity aerobic exercise could enhance the performance of VWM and its sub-processes in adolescents, and long-term intervention showed greater improvement effects compared to acute intervention, especially in the updating sub-process of VWM.

Site-selective synthesis of indanyl-substituted indole derivatives via 1,3-dithiane induced Nazarov cyclization.

We report an efficient site-selective synthetic method to C2 and C3 indanyl-substituted indole derivatives via 1,3-dithianyl induced Nazarov-type cyclization. In particular, C2-selective indanyl-substituted indoles were directly obtained by a BF3·Et2O-promoted sequence of intramolecular C3-C2 migration and Nazarov-type cyclization process.

Synthesis of 1,2-Disubstituted C-Aryl Glycosides via Palladium/Norbornene Cooperative Catalysis.

The Catellani reaction offers an opportunity to address multiple chemical bonds in a single pot. However, it is still quite a challenge to construct fully substituted olefins via this strategy, especially in electron-rich, unstable, and highly functionalized glycals. Herein we report the first palladium-catalyzed Catellani reaction for the direct preparation of 1,2-disubstituted C-aryl glycosides from easily available 2-iodoglycals, bromoaryl, and alkene/alkyne substrates. This transformation exhibits a wide substrate scope, accommodating diverse functional groups and intricate molecular frameworks. This innovative reactivity offers an efficient pathway to valuable 1,2-disubstituted carbohydrate analogues and molecular building blocks, facilitating novel strategic bond disconnections and broadening the reactivity landscape of palladium catalysis.

Preventive effect of pidotimod on reactivated toxoplasmosis in mice.

As one of food-borne parasitic diseases, toxoplasmosis entails the risk of developing reactivation in immunocompromised patients. The synthetic dipeptide pidotimod is a potent immunostimulating agent that improves the immunodefenses in immunodepression. To investigate the efficacy of pidotimod as a preventive treatment, we used a murine model of reactivated toxoplasmosis with cyclophosphamide (CY)-induced immunosuppression. Pidotimod administration significantly restored the body weight and spleen organ index, increased survival time (from 70 to 90%), and decreased the parasitemia (from 80 to 35%) of CY-induced mice with reactivated toxoplasmosis. Cytokine profiles and CD4(+) T cells subpopulation analyses by Cytometric Bead Array and flow cytometry demonstrated that pidotimod treatment resulted in a significant upregulation of pro-inflammatory cytokines (IFN-γ, TNF-α, and IL-2) and Th1 cells (from 3.73 ± 0.39 to 5.88 ± 0.46%) after CY induction in infected mice. Additionally, histological findings and parasite DNA quantification revealed that mice administered with pidotimod had a remarkable reduction of parasite burden (two-log) and amelioration of histopathology in the brains. The in vitro studies showed that pidotimod significantly restored concanavalin A-induced splenocyte proliferation and pro-inflammatory cytokines in the supernatants of splenocyte culture. It could be concluded that the administration of pidotimod in immunocompromised mice significantly increases the Th1-biased immune response, prolongs survival time, and ameliorates the load of parasites in the blood. This is the first report of the preventive effect of pidotimod on reactivated toxoplasmosis.

[Pidotimod inhibits activation of latent Toxoplasma gondii infection induced by dexamethasone in mice].

OBJECTIVE: To study the inhibition effect of pidotimod (PT) on dexamethasone (Dem)-induced reactivated toxoplasmosis in mice. METHODS: A total of 96 female BALB/C mice were infected orally with 30 cysts of Toxoplasma gondii TgCtwh6 strain (genotype Chinese 1). 4 weeks later the mice were divided into three groups (A, B, and C). Mice of group A (Dem+NS) were given Dem [6 mg/(kg x d)] intraperitoneally and 200 microl normal saline given orally. Mice of group B (Dem+PT) were orally given pidotimod [100 mg/(kg x d)] and intraperitoneally injected with Dem[6 mg/(kg x d)] simultaneously. Each mouse in group C received 200 microl normal saline intraperitoneally. The mice were injected and given by gavage for 5 weeks. After treatment, three mice in each group were scarified weekly, and the survival time of the mice was recorded in days. Brain parasite burden and T. gondii DNA copies in serum were detected by quantitative real-time PCR. T cell subsets, cytokine profiles in each group were analyzed by flow cytometry, and CBA kit, respectively. RESULTS: On the second week after Dem administration, parasitemia appeared in group A; in 5 weeks 50% mice had parasitemia again, and 17 mice died. Comparatively, in group B parasitemia appeared on the third week after PT and Dem administration, in 5 weeks 25% mice had parasitemia again, and 7 mice died. Parasitemia did not appear in Group C. On the 21st day after Dem administration, T. gondii DNA copies in brain tissues of group A was (209 +/- 12) x 10(9), significantly higher than (62 +/- 10) x 10(9) in group B treated with PT (n = 3, P < 0.01). Flow cytometry test showed that on the 21st day after Dem administration, the proportions of Th1, Th2 and Treg cells in groups A and B were (4.0 +/- .5)% and (6.1 +/- 1.0)%, (0.6 +/- 0.1)% and (0.5 +/- 0.2)%, and (5.0 +/- 0.9)% and (7.0 +/- 1.2)%, respectively. There was significant difference in the percentages of Th1 and Treg between group B and A (P < 0.01). The levels of IFN-gamma, TNF-alpha in group A were (2.2 +/- 0.7) pg/ml and (20.1 +/- 5.0) pg/ml, respectively, lower than that of group B [(3.6 +/- 0.6) pg/ml and (32.0 +/- 8.0) pg/ml] (P < 0.01). No statistical significance was found in the levels of IL-4 and IL-10 between group A [(2.6 +/- 0.4) pg/ml, (39.0 +/- 6.0) pg/ml] and group B [(2.7 +/- 0.7) pg/ml, (40.0 +/- 8.0) pg/ml] (P > 0.05). CONCLUSION: Pidotimod can inhibit activation of latent Toxoplasma gondii infection induced by dexamethasone in mice. Th1 and Treg cells may contribute to the pidotimod/dexamethasone-induced immunoregulation.

Study of the Microstructure of Coal at Different Temperatures and Quantitative Fractal Characterization.

In order to understand the influence of underground coal fires on coal fractures and pores, mercury intrusion porosimetry (MIP) and scanning electron microscopy (SEM) are combined to study the development of coal pore and fracture under high-temperature treatment and calculate the fractal dimension to analyze the relationship between the development of coal pore and fracture and the fractal dimension. The results show that the volume of pores and fractures of the coal sample (C200) treated at 200 °C (0.1715 mL/g) is greater than that of the coal sample (C400) treated at 400 °C (0.1209 mL/g), and both are greater than the original coal sample (RC) (0.1135 mL/g). The volume increase is mainly due to mesopores and macropores, and the proportions of mesopores and macropores in C200 were 70.15 and 59.97% in C400. The MIP fractal dimension shows a decreasing trend with the increase of temperature, and the connectivity of coal samples improved with the increase of temperature. The changes in volume and three-dimensional fractal dimension of C200 and C400 showed the opposite trend and are related to the different stress of coal matrix at different temperatures. The experimental SEM images confirm that the connectivity of coal fractures and pores improves with the increase of temperature. Based on the SEM experiment, the larger the fractal dimension, the more complex the surface is. The SEM surface fractal dimensions indicate that the surface fractal dimension of C200 is the smallest and that of C400 is the largest, which is consistent with the observations made by SEM. The combination of the two fractal dimensions is used to characterize the self-similarity of coal using the fractal dimension difference. When the temperature increased to 200 °C, the unordered expansion of the coal sample resulted in the largest fractal dimension difference and the lowest self-similarity. When heated to 400 °C, the fractal dimension difference of the coal sample is the smallest, and the microstructure of coal shows a regular groove-like development.

Compound shougong powder inhibits the malignant phenotype of hepatocellular carcinoma cells by targeting the DNA damage repair pathway.

OBJECTIVES: Compound Shougong Powder (SGS), a traditional Chinese medicine formulation, has been used to treat cancer for many years with remarkable efficacy. However, the mechanisms underlying the therapeutic effect of SGS in Hepatocellular carcinoma (HCC) are not completely clear. METHODS: The survival and metastasis of HCC cells were examined by CCK-8 assay, EdU assay, Wound-healing and Transwell assay. The anti-tumour effect of SGS was studied using hoechst 33258 staining and flow cytometry. RNA sequencing was applied to detect the underlying mechanism. Comet DNA, qRT-PCR and WB experiments were performed for validation. In addition, HCC nude mouse model was constructed to detect SGS effect in vivo. KEY FINDINGS: SGS inhibited the proliferation, migration and invasion of HCC cells and induced apoptosis in vitro. In addition, SGS also suppressed tumour growth in a nude mouse model of HCC in a dose-dependent manner. RNA sequencing of the suitably treated HCC cells revealed significant changes in the expression levels of genes involved in the DNA damage repair pathway. The sequencing results were verified by Comet DNA, qRT-PCR, WB assays and molecular docking. CONCLUSIONS: Taken together, SGS inhibits the malignant phenotype of HCC cells by down-regulating DNA repair genes and consequently inducing DNA damage.
