Abstract
The newly emerged SARS-CoV-2 caused a global pandemic with astonishing mortality and morbidity. The mechanisms underpinning its highly infectious nature remain poorly understood. We report here that SARS-CoV-2 exploits cellular CTP synthetase 1 (CTPS1) to promote CTP synthesis and suppress interferon (IFN) induction. Screening a SARS-CoV-2 expression library identified ORF7b and ORF8 that suppressed IFN induction via inducing the deamidation of interferon regulatory factor 3 (IRF3). Deamidated IRF3 fails to bind the promoters of classic IRF3-responsible genes, thus muting IFN induction. Conversely, a shRNA-mediated screen focused on cellular glutamine amidotransferases corroborated that CTPS1 deamidates IRF3 to inhibit IFN induction. Functionally, ORF7b and ORF8 activate CTPS1 to promote de novo CTP synthesis while shutting down IFN induction. De novo synthesis of small-molecule inhibitors of CTPS1 enabled CTP depletion and IFN induction in SARS-CoV-2 infection, thus impeding SARS-CoV-2 replication. Our work uncovers a strategy that a viral pathogen couples immune evasion to metabolic activation to fuel viral replication. Inhibition of the cellular CTPS1 offers an attractive means for developing antiviral therapy that would be resistant to SARS-CoV-2 mutation.

Abstract
BACKGROUND Although several brain networks play important roles in cervical dystonia (CD) patients, regional homogeneity (ReHo) changes in CD patients have not been clarified. We investigated to explore ReHo in CD patients at rest and analyzed its correlations with symptom severity as measured by Tsui scale. METHODS A total of 19 CD patients and 21 gender-, age-, and education-matched healthy controls underwent fMRI scans at rest state. Data were analyzed by ReHo method. RESULTS Patients showed increased ReHo in the right cerebellum crus I and decreased ReHo in the right superior medial prefrontal cortex (MPFC). Moreover, the right precentral gyrus, right insula, and bilateral middle cingulate gyrus also showed increased ReHo values. A significantly positive correlation was observed between ReHo value in the right cerebellum crus I and symptom severity (p < 0.05). CONCLUSIONS Our investigation suggested abnormal ReHo existed in brain regions of the "pain matrix" and salience network (the right insula and bilateral middle cingulate gyrus), the motor network (the right precentral gyrus), the cerebellum and MPFC and further highlighted the significance of these networks in the pathology of CD.

Abstract
The potential involvement of T classification-related genes in renal clear cell carcinoma (ccRCC) must be further explored. Public data were obtained from The Cancer Genome Atlas (TCGA) database. An overall survival (OS) predictive model was developed and validated (TCGA train, 5 years, AUC = 0.73, 3 years, AUC = 0.73, 1 year, AUC = 0.76; TCGA test, 5 years, AUC = 0.74, 3 years, AUC = 0.65, 1 year, AUC = 0.73; TCGA all, 5 years, AUC = 0.72, 3 years, AUC = 0.71, 1 year, AUC = 0.75). Finally, ENAM was selected for further analysis. In vitro experiment indicated that ENMA is downregulated in ccRCC, and its knockdown could promote proliferation in two cancer cell lines (OSRC-2 and SW839). Immune infiltration analysis revealed that ENAM could remarkably increase the content of cytotoxic cells, NK CD56 cells, NK cells and CD8+ T cells in the tumor immune microenvironment, which may be one reason for its tumor-inhibiting effect. In summary, ENAM may suppress cell proliferation in ccRCC and can be used as a potential reference value for the relief and immunotherapy of ccRCC.

Abstract
Soybean is an important legume crop that displays the classic shade avoidance syndrome (SAS), including exaggerated stem elongation, which leads to lodging and yield reduction under density farming conditions. Here, we compared the effects of two shade signals, low red light to far-red light ratio (R:FR) and low blue light (LBL), on soybean status and revealed that LBL predominantly induces excessive stem elongation. We used CRISPR-Cas9-engineered Gmcry mutants to investigate the functions of seven cryptochromes (GmCRYs) in soybean and found that the four GmCRY1s overlap in mediating LBL-induced SAS. Light-activated GmCRY1s increase the abundance of the bZIP transcription factors STF1 and STF2, which directly upregulate the expression of genes encoding GA2 oxidases to deactivate GA1 and repress stem elongation. Notably, GmCRY1b overexpression lines displayed multiple agronomic advantages over the wild-type control under both dense planting and intercropping conditions. Our study demonstrates the integration of GmCRY1-mediated signals with the GA metabolic pathway in the regulation of LBL-induced SAS in soybean. It also provides a promising option for breeding lodging-resistant, high-yield soybean cultivars in the future.

Abstract
Herpes simplex viruses (HSVs) are experts in establishing persistent infection in immune-competent humans, in part by successfully evading immune activation through diverse strategies. Upon HSV infection, host deploys pattern recognition receptors (PRRs) to recognize various HSV-associated molecular patterns and mount antiviral innate immune responses. In this review, we describe recent advances in understanding the contributions of cytosolic PRRs to detect HSV and the direct manipulations on these receptors by HSV-encoded viral proteins as countermeasures. The continuous update and summarization of these mechanisms will deepen our understanding on HSV-host interactions in innate immunity for the development of novel antiviral therapies, vaccines and oncolytic viruses.

Abstract
Previous studies have found the relationship between cholesterol biosynthesis pathway genes and the risk or prognosis of prostate cancer (PCa), while there is no definite evidence that genetic variants in the cholesterol biosynthesis pathway gene is related to PCa risk. Consequently, we performed this study to explore the associations of single-nucleotide polymorphisms (SNPs) in the cholesterol biosynthesis pathway with PCa risk. We systematically evaluated the association of SNPs in 21 cholesterol biosynthesis pathway genes with the risk of PCa using the Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial database using a logistic regression model. Gene expression data of PCa from Gene Expression Omnibus (GEO) datasets and the Cancer Genome Atlas (TCGA) database were applied for mRNA expression analysis. The TCGA database was used to perform expression quantitative trait loci (eQTL) analysis. The interaction between demographic factors and SNPs was analyzed using two-by-four tables. We found T allele of rs67415672 in HMGCS1 is a significant protective allele of PCa [adjusted odds ratio (OR) = 0.90, 95% confidence interval (CI) = 0.83-0.97, P = 4.16 × 10-3]. Moreover, rs67415672 was an eQTL for HMGCS1 (P = 2.23 × 10-6). The expression of HMGCS1 significantly decreased in PCa primary tumors than that in normal tissues. These findings indicated that the HMGCS1 rs67415672 might be possible functional susceptibility loci for PCa.

Abstract
High-fat diet (HFD) decreases insulin sensitivity. How high-fat diet causes insulin resistance is largely unknown. Here, we show that lean mice become insulin resistant after being administered exosomes isolated from the feces of obese mice fed a HFD or from patients with type II diabetes. HFD altered the lipid composition of exosomes from predominantly phosphatidylethanolamine (PE) in exosomes from lean animals (L-Exo) to phosphatidylcholine (PC) in exosomes from obese animals (H-Exo). Mechanistically, we show that intestinal H-Exo is taken up by macrophages and hepatocytes, leading to inhibition of the insulin signaling pathway. Moreover, exosome-derived PC binds to and activates AhR, leading to inhibition of the expression of genes essential for activation of the insulin signaling pathway, including IRS-2, and its downstream genes PI3K and Akt. Together, our results reveal HFD-induced exosomes as potential contributors to the development of insulin resistance. Intestinal exosomes thus have potential as broad therapeutic targets.

Abstract
Silent brain infarction is a special type of cerebral infarction, which can be detected by MRI or CT. The most patients with silent brain infarction show no symptoms, but some have mild depression, vascular dementia and other symptoms that are easily overlooked. Silent brain infarction is one of the risk factors for symptomatic cerebral infarction, it can develop into symptomatic cerebral infarction placing a heavy burden on families and society. Therefore, it's prevention and treatment should be as important as symptomatic cerebral infarction. However, the pathogenesis of silent brain infarction has not been elucidated. Studies have shown that silent brain infarction models have been established in rats and mice. But compared with other animals, non-human primates are more similar to humans in neuroanatomical structure and clinical characteristics. Therefore, this study is the first time to explore the silent brain infarction model in cynomolgus macaques. In this study, a model of silent brain infarction was established by endovascular intervention using balloon occlusion at the end of internal carotid artery for 45 min, which can lay a foundation for the future research on the pathological mechanism of silent brain infarction.

Abstract
Pullorum disease is one of the most common diarrhea-related diseases caused by Salmonella enterica subspecies enterica serovar Gallinarum biovar Pullorum (S Pullorum); it negatively affects the poultry industry. However, limited studies have explored the association between the gut microbiota and S Pullorum infection in chickens. In the present study, we performed a microbiome comparison and a microbiome genome-wide association study (mGWAS) to investigate the association among the host genetics, the gut microbiota, and pullorum disease in chickens. We found that S Pullorum infection in chickens could alter the abundance of 39 bacterial genera (P < 0.05). The altered structure and composition of the gut microbiota were also detected in the offspring. mGWAS results revealed host genetic variants to be prominently associated with gut microbial diversity and individual microbes. The pathogens Pelomonas and Brevundimonas, which had a high abundance in positive parent chickens and their offspring, were significantly associated with several genetic mutations in immunity-related genes, such as TGIF1, TTLL12, and CCR7 This finding explained why Pelomonas and Brevundimonas were heritable in S Pullorum-infected chickens. The heritable gut microbes and identified genetic variants could provide references for the selection of resistant chickens and the elimination of pullorum disease.IMPORTANCE The present study investigated the association among the host genome, the gut microbiome, and S Pullorum infection in chickens. The results suggested that the gut microbial structure is altered in S Pullorum-infected chickens. The diversity and abundance of the gut microbiota remarkably differed between the offspring coming from S Pullorum-positive and S Pullorum-negative chickens. Heritable gut microbiota were detected in the offspring. Moreover, host genetic variants were associated with microbial diversity and individual gut microbes. The pathogens Pelomonas and Brevundimonas, which exhibited a high heritability in S Pullorum-positive parents and their offspring, were associated with several genetic mutations in immunity-related genes.

Abstract
The binding of PAHs with DNA to form PAH-DNA adducts is a crucial step in PAH-induced carcinogenesis. How functional groups affect this binding is largely unknown. Here, we observed that functional group substitutions strongly inhibited PAH-DNA binding. Additionally, -OH substitution has the most potent inhibitory effect as it causes the smallest change in the electrostatic surface potential. Fourier transform infrared spectroscopy and molecular docking analyses demonstrated that PAH derivatives bind with guanine via intercalation and groove binding and then non-specifically insert into the major/minor grooves of DNA. Quantum chemical calculations suggested that hydrogen/halogen bonding may be essential in affecting the binding of functional group-substituted PAHs with DNA. It was further revealed that Log KOA and the PAH derivatives' melting points correlated significantly with binding affinity, implying that changes in the physicochemical characteristics are important factors. This study opens a new window for understanding the relationship between highly toxic PAH derivatives and genetic materials.

Abstract
Lipid rafts are microdomains on plasma membrane that contain high levels of cholesterol and sphingolipids. Because of the detergent-resistant property of lipid rafts, lipid rafts isolated by methods that use detergents frequently yield different results. Artifacts can also be introduced through the use of detergents. These limitations could be overcome with a detergent-free method which eliminates possible artificial influences. Importantly, lipid rafts prepared with a detergent-free method is more compatible to mass spectrometric analysis since the ion suppression effect is largely reduced.This chapter describes a detergent-free two-step method for preparation of lipid rafts. Firstly, a purified plasma membrane fraction is prepared from cells by sedimentation of the postnuclear supernatant (PNS) in a Percoll gradient. Secondly, the as-prepared plasma membranes are sonicated to release lipid rafts which are further isolated by flotation in a continuous gradient of Optiprep solution. Then, we introduce a typical shotgun lipidomics workflow that can be used as a cost-effective and relatively high throughput method to determine the lipidomes of lipid rafts.The method also makes an easy start for lipidomics studies.

Abstract
Pyrethroids may be related to male reproductive system damage. However, the results of many previous studies are contradictory and uncertain. Therefore, a systematic review and a meta-analysis were performed to assess the relationship between pyrethroid exposure and male reproductive system damage. A total of 72 articles were identified, among which 57 were selected for meta-analysis, and 15 were selected for qualitative analysis. Pyrethroid exposure affected sperm count (SMD= -2.0424; 95% CI, -2.4699 to -1.6149), sperm motility (SMD=-3.606; 95% CI, -4.5172 to -2.6948), sperm morphology (SMD=2.686; 95% CI, 1.9744 to 3.3976), testis weight (SMD=-1.1591; 95% CI, -1.6145 to -0.7038), epididymal weight (SMD=-1.1576; 95% CI, -1.7455 to -0.5697), and serum testosterone level (SMD=-1.9194; 95% CI, -2.4589 to -1.3798) in the studies of rats. We found that gestational and lactational exposure to pyrethroids can reduce sperm count (SMD=1.8469; 95% CI, -2.9010 to -0.7927), sperm motility (SMD=-2.7151; 95% CI, -3.9574 to -1.4728), testis weight (SMD=-1.4361; 95% CI, -1.8873 to -0.9848), and epididymal weight (SMD=-0.6639; 95% CI, -0.9544 to -0.3733) of F1 offspring. Exposure to pyrethroids can increase malondialdehyde (SMD=3.3451; 95% CI 1.9914 to 4.6988) oxide in testes and can reduce the activities of glutathione (SMD=-2.075; 95% CI -3.0651 to -1.0848), superoxide dismutase (SMD=-2.4856; 95% CI -3.9612 to -1.0100), and catalase (SMD=-2.7564; 95% CI -3.9788 to -1.5340). Pyrethroid exposure and oxidative stress could damage male sperm quality. Gestational and lactational pyrethroid exposure affects the reproductive system of F1 offspring.

Abstract
BACKGROUND Ocular myasthenia gravis and Graves' ophthalmopathy are autoimmune diseases that are mediated by membrane receptors and share many identical clinical processes. Poland syndrome is a rare congenital deformity characterized by defects of the ipsilateral hand and the chest wall, and it is usually associated with hypoplasia of ipsilateral pectoral muscles and homolateral breast. However, to the best of our knowledge, the co-occurrence of these diseases has never been reported. In this study, we present a man with Poland syndrome who was diagnosed with Graves' ophthalmopathy and ocular myasthenia gravis in succession. CASE PRESENTATION A 43-year-old man presented with bilateral upper eyelid ptosis, bilateral eye protrusion, bilateral eye movement disorder and malformation of the right hand. Asymmetrical malformation of the chest wall and ipsilateral hand deformity were shown as Poland syndrome. He was diagnosed with ocular myasthenia gravis and Graves' ophthalmopathy on the basis of clinical manifestations and laboratory examinations, including bilateral exophthalmos and progressive asymmetrical ophthalmoparesis without pupillary dysfunction, positive autoantibody tests, repetitive nerve stimulation tests, and computed tomography scans. Treatments with pyridostigmine bromide, thymectomy, and prednisone led to partial clinical improvement. After 13 months of follow-up, the symptoms of drooping eyelids were partially improved, but the eyeball protrusion and right hand deformity remained unchanged. CONCLUSIONS We report the first case of co-occurrence of ocular myasthenia gravis, Graves' ophthalmopathy, and Poland syndrome. Genetic predisposition and immune dysregulation might be the pathogenesis of the association.

Abstract
Cancer-associated fibroblasts (CAFs) are the majority cell population of tumor stroma, and they not only play important roles in tumor growth and metastasis, but they also form a protective physical barrier for cancer cells. Herein, we designed a fibroblast activation protein-α (FAP-α)-adaptive polymeric micelle based on hyaluronic acid and curcumin conjugates. The polymeric micelle is composed of a CD44-targeting shell and a FAP-α-cleavable polyethylene glycol (PEG) coating. When FAP-α is encountered on the surface of CAFs in the tumor microenvironment, the PEG layer is released, hyaluronic acid is recovered on the surface of nanoparticles, and the nanoparticles effectively inhibit the growth of tumor cells and CAFs through CD44-mediated endocytosis. The FAP-α-adaptive polymeric micelle exhibited potent anti-cancer efficacy by enhancing CAF apoptosis and reducing collagen in tumor tissues. Collectively, FAP-α-adaptive nanoparticles may be a promising method for antitumor anticancer treatments via reprogramming of stroma fibrosis.

Abstract
OBJECTIVE To investigate the clinical characteristics and treatment strategies of prostatic mucinous adenocarcinoma (PMAC). METHODS We retrospectively analyzed the clinical data on 10 cases of PMAC treated in the First Affiliated Hospital of Nanjing Medical University from January 2014 to June 2018. The patients were aged 51-79 (65 ± 14) years, with a medium PSA level of 89 (14.63-128.05) μg/L and Gleason scores of 3 + 3 in 1 case, 3 + 4 in 2, 4 + 3 in 1 and 8 in 6 cases preoperatively, 1 treated by robot-assisted radical prostatectomy and the other 9 by laparoscopic radical prostatectomy. We conducted pelvic cavity lymph node dissection for all the patients and analyzed their prognosis and survival. RESULTS Operations were successfully completed in all the cases. Pathological examination revealed 2 cases of mucinous adenocarcinoma with signet ring cell carcinoma in the 10 PMAC patients, 2 at stage ≤T2b, 5 at stage ≥T2c, 3 positive at pelvic lymph node dissection and 5 positive at the incision margin. The patients were followed up for 6-48 (median 26) months. Four of the patients were found with biochemical recurrence within 2 years after operation and treated by androgen-deprivation therapy, radiotherapy and chemotherapy, which reduced the PSA level to <1.0 μg/ml in all the 4 cases. CONCLUSIONS PMAC has a good prognosis. Radical surgery is recommended for moderate and low-risk PMAC and the patients with postoperative biochemical recurrence can benefit from comprehensive treatment of total androgen blockade.

Abstract
In plants, 22-nucleotide small RNAs trigger the production of secondary small interfering RNAs (siRNAs) and enhance silencing. DICER-LIKE2 (DCL2)-dependent 22-nucleotide siRNAs are rare in Arabidopsis (Arabidopsis thaliana) and are thought to function mainly during viral infection; by contrast, these siRNAs are abundant in many crops such as soybean (Glycine max) and maize (Zea mays). Here, we studied soybean 22-nucleotide siRNAs by applying CRISPR-Cas9 to simultaneously knock out the two copies of soybean DCL2, GmDCL2a and GmDCL2b, in the Tianlong1 cultivar. Small RNA sequencing revealed that most 22-nucleotide siRNAs are derived from long inverted repeats (LIRs) and disappeared in the Gmdcl2a/2b double mutant. De novo assembly of a Tianlong1 reference genome and transcriptome profiling identified an intronic LIR formed by the chalcone synthase (CHS) genes CHS1 and CHS3 This LIR is the source of primary 22-nucleotide siRNAs that target other CHS genes and trigger the production of secondary 21-nucleotide siRNAs. Disruption of this process in Gmdcl2a/2b mutants substantially increased CHS mRNA levels in the seed coat, thus changing the coat color from yellow to brown. Our results demonstrated that endogenous LIR-derived transcripts in soybean are predominantly processed by GmDCL2 into 22-nucleotide siRNAs and uncovered a role for DCL2 in regulating natural traits.

Abstract
Extensive research has revealed the pivotal role of kinesin family member 20A (KIF20A) in cancer. However, its latent involvement in renal clear cell carcinoma (ccRCC) still remains unclear. Thus, here we explored the role of KIF20A in ccRCC. For this, a series of software including R (v. 3.6.1), SPSS (v. 23), ImageJ and FlowJo were used for the analyses. Open-access data were obtained from The Cancer Genome Atlas (TCGA), International Cancer Genome Consortium (ICGC) and Gene Expression Omnibus (GEO) databases. Weighted Gene Co-expression Network Analysis (WGCNA) was used for module gene identification. In vitro results indicated that KIF20A expression is up-regulated in ccRCC tissue. KIF20A knockdown was able to inhibite cell proliferation and invasion of kidney A498 and Caki-1 cells. Meanwhile, KIF20A showed a strong association with immune infiltration. Particularly, KIF20A had a strong positive correlation with Th2 cells, Treg cells and Macrophages, but a negative correlation with Th17 cells, Mast cells and NK cells. These correlations may suggest the use of KIF20A as an underlying immunotherapy target in ccRCC. Our data indicated that KIF20A may promote cell invasion and proliferation in ccRCC, thus serving as an independent tumor marker and a putative therapeutic target.

Abstract
Objective Sepsis-associated intestinal injury has a higher morbidity and mortality in patients with sepsis, but there is still no effective treatment. Our research team has proven that inhaling 2% hydrogen gas (H2) can effectively improve sepsis and related organ damage, but the specific molecular mechanism of its role is not clear. In this study, isobaric tags for relative and absolute quantitation (iTRAQ)-based quantitative proteomics analysis was used for studying the effect of H2 on intestinal injury in sepsis. Methods Male C57BL/6J mice were used to prepare a sepsis model by cecal ligation and puncture (CLP). The 7-day survival rates of mice were measured. 4-kd fluorescein isothiocyanate-conjugated Dextran (FITC-dextran) blood concentration measurement, combined with hematoxylin-eosinstain (HE) staining and Western blotting, was used to study the effect of H2 on sepsis-related intestinal damage. iTRAQ-based liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis was used for studying the proteomics associated with H2 for the treatment of intestinal injury. Results H2 can significantly improve the 7-day survival rates of sepsis mice. The load of blood and peritoneal lavage bacteria was increased, and H2 treatment can significantly reduce it. CLP mice had significant intestinal damage, and inhalation of 2% hydrogen could significantly reduce this damage. All 4194 proteins were quantified, of which 199 differentially expressed proteins were associated with the positive effect of H2 on sepsis. Functional enrichment analysis indicated that H2 may reduce intestinal injury in septic mice through the effects of thyroid hormone synthesis and nitrogen metabolism signaling pathway. Western blot showed that H2 was reduced by down-regulating the expressions of deleted in malignant brain tumors 1 protein (DMBT1), insulin receptor substrate 2 (IRS2), N-myc downregulated gene 1 (NDRG1) and serum amyloid A-1 protein (SAA1) intestinal damage in sepsis mice. Conclusion A total of 199 differential proteins were related with H2 in the intestinal protection of sepsis. H2-related differential proteins were notably enriched in the following signaling pathways, including thyroid hormone synthesis signaling pathway, nitrogen metabolism signaling pathways, digestion and absorption signaling pathways (vitamins, proteins and fats). H2 reduced intestinal injury in septic mice by down-regulating the expressions of SAA1, NDRG1, DMBT1 and IRS2.

Abstract
PURPOSE A primary lumbar hernia is a rare entity that requires surgical management, but the preferred technique has not been established. We herein describe a standardized and reproducible retroperitoneal totally endoscopic prosthetic (TEP) repair technique for primary lumbar hernias. METHODS Ten adult patients with primary lumbar hernias underwent retroperitoneal TEP repair from February 2019 to July 2020. A sufficient retroperitoneal space was established to accommodate a non-coated polypropylene mesh to reinforce the weakened flank area, and hernia content reduction and defect closure were then performed. The patients' clinical data were prospectively collected and analyzed. RESULTS Nine patients had a primary superior lumbar hernia and one patient had a primary diffuse lumbar hernia. All operations were successfully performed without serious intraoperative complications. The mean defect area was 6.4 ± 2.8 cm2 (range 4-12 cm2), and the mean mesh area was 144.6 cm2 (range 130-180 cm2). The average operative time (skin to skin) was 49.0 ± 5.7 min (range 40-60 min), and intraoperative bleeding was minimal. The mean visual analog pain scale score at rest on the first postoperative day was 2.2 (range 2-3). The average length of postoperative stay was 1.5 days (range 1-2 days). No serious postoperative complications occurred. No recurrence, chronic pain, or mesh infection occurred during a mean follow-up period of 7.5 months. CONCLUSIONS The retroperitoneal TEP repair for primary lumbar hernias is safe, efficient, and reproducible. Anti-adhesive coated meshes and fixation tackers are not required, making this a cost-effective procedure that is worthy of recommendation.

Abstract
Comparative genomic analysis within Asian cultivated rice (Oryza sativa L.) populations has greatly enriched our knowledge regarding rice domestication and the divergence of the indica and japonica subspecies, while study on genomic regions associated with improvement within the indica subspecies is still limited. Here, through combined investigation of 2,429 indica cultivar genomes from public sequencing projects, we depict the improvement of modern indica rice in China. We identify three subgroups within indica populations: two geographically distinct, historical subgroups indica I (Ind_I) and indica III (Ind_III) and a modern subgroup indica II (Ind_II). The modern indica subgroup Ind_II shows admixture of the other two subgroups and enrichment of alleles that had been low-frequency in the other two subgroups. The Chinese indica cultivars exhibit a strong subgroup component change from Ind_I to Ind_II in the 1980s. Through haplotype-based comparative analysis, we detect 187 regions associated with separation of Ind_II compared to Ind_I or Ind_III. Within those regions we find strong representation of beneficial agricultural production-related alleles in Ind_II and a positive correlation between grain yield and number of differentiated haplotypes. Phenotypic features of long and slender grain, small tiller angle and decreased flowering time were detected for Ind_II. Through haplotype-based comparative analysis between rice subpopulations and subspecies, we find differentiated haplotypes not only from indica itself but also from japonica and aus, suggesting that introgression from other rice sub-populations has substantially contributed to modern indica rice breeds. These results help clarify the evolutionary landscape of modern indica rice in China and provide useful targets for future improvement.

Abstract
Diabetic neuropathy is a major complication of diabetes. Current treatment options alleviate pain but do not stop the progression of the disease. At present, there are no approved disease-modifying therapies. Thus, developing more effective therapies remains a major unmet medical need. Seeking to better understand the molecular mechanisms driving peripheral neuropathy, as well as other neurological complications associated with diabetes, we performed spatiotemporal lipidomics, biochemical, ultrastructural, and physiological studies on PNS and CNS tissue from multiple diabetic preclinical models. We unraveled potentially novel molecular fingerprints underlying nerve damage in obesity-induced diabetes, including an early loss of nerve mitochondrial (cardiolipin) and myelin signature (galactosylceramide, sulfatide, and plasmalogen phosphatidylethanolamine) lipids that preceded mitochondrial, myelin, and axonal structural/functional defects; started in the PNS; and progressed to the CNS at advanced diabetic stages. Mechanistically, we provided substantial evidence indicating that these nerve mitochondrial/myelin lipid abnormalities are (surprisingly) not driven by hyperglycemia, dysinsulinemia, or insulin resistance, but rather associate with obesity/hyperlipidemia. Importantly, our findings have major clinical implications as they open the door to novel lipid-based biomarkers to diagnose and distinguish different subtypes of diabetic neuropathy (obese vs. nonobese diabetics), as well as to lipid-lowering therapeutic strategies for treatment of obesity/diabetes-associated neurological complications and for glycemic control.

Abstract
Background Since December 2019, the novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), first spread quickly in Wuhan, China, then globally. Based on previously published evidence, ACE2 and TMPRSS2 are both pivotal entry molecules that enable cellular infection by SARS-CoV-2. Also, increased expression of pro-inflammatory cytokines, or a “cytokine storm,” is associated with multiple organ dysfunction syndrome often observed in critically ill patients. Methods We investigated the expression pattern of ACE2 and TMPRSS2 in major organs in the human body, especially in specific disease conditions. Multiple sequence alignment of ACE2 in different species was used to explain animal susceptibility. Moreover, the cell-specific expression patterns of ACE2 and cytokine receptors in the urinary tract were assessed using single-cell RNA sequencing (scRNA-seq). Additional biological relevance was determined through Gene Set Enrichment Analysis (GSEA) using an ACE2-specific signature. Results Our results revealed that ACE2 and TMPRSS2 were highly expressed in genitourinary organs. ACE2 was highly and significantly expressed in the kidney among individuals with chronic kidney diseases or diabetic nephropathy. In single cells, ACE2 was primarily enriched in gametocytes in the testis and renal proximal tubules. The receptors for pro-inflammatory cytokines, especially IL6ST, were notably concentrated in endothelial cells, macrophages, spermatogonial stem cells in the testis, and renal endothelial cells, which suggested the occurrence of alternative damaging autoimmune mechanisms. Conclusion This study provided new insights into the pathogenic mechanisms of SARS-CoV-2 that underlie the clinical manifestations observed in the human testis and kidney. These observations might substantially facilitate the development of effective treatments for this rapidly spreading disease.

Abstract
Ferroelectricity has an excellent reversible polarization conversion behavior under an external electric field. Herein, we propose an interesting strategy to alleviate the shuttle effect of lithium-sulfur battery by utilizing ferroelectric metal-organic framework (FMOF) as a host material for the first time. Compared to other MOF with same structure but without ferroelectricity and commercial carbon black, the cathode based on FMOF exhibits a low capacity decay and high cycling stability. These results demonstrate that the polarization switching behaviors of FMOF under the discharge voltage of lithium-sulfur battery can effectively trap polysulfides by polar-polar interactions, decrease polysulfides shuttle and improve the electrochemical performance of lithium-sulfur battery.

Abstract
In the recent few years, plenty of research has shown that microRNA (miRNA) is likely to be involved in the formation of many human diseases. So effectively predicting potential associations between miRNAs and diseases helps to understand the development and treatment of diseases. In this study, an edge perturbation based method is proposed for predicting potential miRNA-disease association (EPMDA). Different from the previous studies, we design an feature vector to describe each edge of a graph by structural Hamiltonian information. Moreover, the extracted features are used to train a multi-layer perception model to predict the candidate disease-miRNA associations. The experimental results on the HMDD dataset show that EPMDA achieves the AUC value of 0.9818 through 5-fold cross-validation, which improves the AUC values by approximately 3.5 percent compared to the latest method DeepMDA. For the leave-one-disease-out cross-validation, EPMDA achieves the AUC value of 0.9371, which improves the AUC values by approximately 7.4 percent compared to DeepMDA. In the case study, we verify the prediction performance of EPMDA on three human diseases. As a result, there are 42, 46, and 41 of the top 50 predicted miRNAs for these three diseases which are confirmed by the published experimental discoveries, respectively.

Abstract
Cancer stem cells (CSCs) have been characterized by several exclusive features that include differentiation, self-renew, and homeostatic control, which allows tumor maintenance and spread. Recurrence and therapeutic resistance of head and neck squamous cell carcinomas (HNSCC) have been identified to be attributed to CSCs. However, the biomarkers led to the development of HNSCC stem cells remain less defined. In this study, we quantified cancer stemness by mRNA expression-based stemness index (mRNAsi), and found that mRNAsi indices were higher in HNSCC tissues than that in normal tissue. A significantly higher mRNAsi was observed in HPV positive patients than HPV negative patients, as well as in male patients than in female patients. The 8-mRNAsi signature was identified from the genes in two modules which were mostly related to mRNAsi screened by weighted gene co-expression network analysis. In this prognostic signatures, high expression of RGS16, LYVE1, hnRNPC, ANP32A, and AIMP1 focus in promoting cell proliferation and tumor progression. While ZNF66, PIK3R3, and MAP2K7 are associated with a low risk of death. The riskscore of eight signatures have a powerful capacity for 1-, 3-, 5-year of overall survival prediction (5-year AUC 0.77, 95% CI 0.69-0.85). These findings based on stemness indices may provide a novel understanding of target therapy for suppressing HNSCC stem cells.

Abstract
Systematic design and self-assembly of metal-organic polyhedra with predictable configurations has been a long-standing challenge in crystal engineering. Herein a concave polyoxovanadate cluster, [V6 O6 (OCH3 )9 (SO4 )4 ]5- , which can be generated in situ under specific reaction conditions, is reported. Based on this cluster, a potential trivalent molecular building block, [V6 O6 (OCH3 )9 (SO4 )(CO2 )3 ]2- , can be obtained by the bridging-ligand-substitution strategy and it possesses appropriate angle information for the design of molecular cubes. Utilizing the face-directed assembly of the trivalent molecular building block and a diverse set of tetratopic carboxylate linkers, a series of metal-organic cubes (VMOC-1-VMOC-5) with the same topology but different functionalities and dimensions were designed and constructed. An inclusion study using VMOC-3 shows that they are potential molecular receptors for selective capture of size-matching polycyclic aromatic hydrocarbon guest molecules.

Abstract
Background Autophagy was a significant catabolic process which played a critical role in the maintenance of cellular homeostasis and viability in a stressed state. The dysregulation of autophagy was correlated with various diseases. The aim of our study was to develop a prognostic signature for papillary renal cell carcinoma (RCC). Methods First, 40 differently expressed genes related with autophagy (ARGs) were examined via high-throughput sequencing and large-scale databases. Then, functional enrichment analysis was performed to explore the biological attributes of these ARGs. The Cox proportional hazard regression hinted that four ARGs (P4HB, BIRC5, NGR1 and PRKN) were significantly correlated with overall survival (OS). Thus, we got genes with prognostic value. Finally, a prognostic index (PI) was constructed. Results After identifying the 4 ARGs, we profiled our risk signature. Based on the PI we developed, papillary RCC patients were stratified into high-risk and low-risk groups. High-risk patients had significant shorter OS than low-risk patients (P<0.001) and the mortality of high scoring patients was higher than low scoring patients. Additionally, we explored the relationship between the 4 ARGs and clinical parameters and found that the expression of P4HB, BIRC5 and NGR1 was correlated with clinicopathological features. Conclusions Our study suggested that the four-gene signature was an independent prognostic factor which could act as a novel indicator for the prognosis of papillary RCC.

Abstract
Recently N6-Methyladenosine (m6A) has been identified to guide the interaction of RNA-binding protein hnRNP C and their target RNAs, which is termed as m6A-switches. We systematically investigated the association between genetic variants in m6A-switches and bladder cancer risk. A two-stage case-control study was performed to systematically calculate the association of single nucleotide polymorphisms (SNPs) in 2798 m6A-switches with bladder cancer risk in 3,997 subjects. A logistic regression model was used to assess the effects of SNPs on bladder cancer risk. A series of experiments were adopted to explore the role of genetic variants of m6A-switches. We identified that rs5746136 (G > A) of SOD2 in m6A-switches was significantly associated with the reduced risk of bladder cancer (additive model in discovery stage: OR = 0.80, 95% CI 0.69-0.93, P = 3.6 × 10-3; validation stage: adjusted OR = 0.88, 95% CI 0.79-0.99, P = 3.0 × 10-2; combined analysis: adjusted OR = 0.85, 95% CI 0.78-0.93, P = 4.0 × 10-4). The mRNA level of SOD2 was remarkably lower in bladder cancer tissues than the paired adjacent samples. SNP rs5746136 may affect m6A modification and regulate SOD2 expression by guiding the binding of hnRNP C to SOD2, which played a critical tumor suppressor role in bladder cancer cells by promoting cell apoptosis and inhibiting proliferation, migration and invasion. In conclusion, our findings suggest the important role of genetic variants in m6A modification. SOD2 polymorphisms may influence the expression of SOD2 via an m6A-hnRNP C-dependent mechanism and be promising predictors of bladder cancer risk.

Abstract
OBJECTIVE Breast cancer (BC) is one of the most ordinary fatal cancers. Recent studies have identified the vital role of long noncoding RNAs (lncRNAs) in the development and progression of BC. In this research, lncRNA SNHG14 was studied to identify how it functioned in the development and metastasis of BC. PATIENTS AND METHODS SNHG14 expression of tissues was detected by Real Time-quantitative Polymerase Chain Reaction (RT-qPCR) in 50 paired patients with BC. And cell proliferation assay, colony formation assay, and transwell assay were enrolled to observe the biological behavior changes of BC cells through gain or loss of SNHG14. In addition, luciferase assays and RNA immunoprecipitation assay (RIP) were performed to discover the potential targets of SNHG14 in BC cells. RESULTS SNHG14 expression level of BC samples was higher than that of adjacent ones. Besides, cell growth ability and cell invaded ability of BC cells were inhibited after SNHG14 was silenced, while cell growth ability and cell invaded ability of BC cells were promoted after SNHG14 was overexpressed. In addition, miR-193a-3p was upregulated after silence of SNHG14 in BC cells, while miR-193a-3p was downregulated after overexpression of SNHG14 in BC cells. Furthermore, luciferase assays and RNA immunoprecipitation assay (RIP) showed that miR-193a-3p was a direct target of SNHG14 in BC. CONCLUSIONS Our study uncovers a new oncogene in BC and suggests that SNHG14 could enhance BC cell proliferation and invasion via sponging miR-193a-3p, which provided a novel therapeutic target for BC patients.

Abstract
Inspired by the structures of virus capsids, chemists have long pursued the synthesis of their artificial molecular counterparts through self–assembly. Building nanoscale hierarchical structures to simulate double-shell virus capsids is believed to be a daunting challenge in supramolecular chemistry. Here, we report a double-shell cage wherein two independent metal–organic polyhedra featuring Platonic and Archimedean solids are nested together. The inner (3.2 nm) and outer (3.3 nm) shells do not follow the traditional “small vs. large” pattern, but are basically of the same size. Furthermore, the assembly of the inner and outer shells is based on supramolecular recognition, a behavior analogous to the assembly principle found in double-shell viruses. These two unique nested characteristics provide a new model for Matryoshka–type assemblies. The inner cage can be isolated individually and proves to be a potential molecular receptor to selectively trap guest molecules. Supramolecular constructs that mimic complex biological assemblies are synthetically challenging. Here, the authors present a double-shell cage wherein two independent metal-organic polyhedra are nested together in a manner analogous to that found in double-shell virus capsids.

Abstract
The 3 major subphenotypes observed in patients with nonsyndromic orofacial clefts (NSOFCs) are nonsyndromic cleft lip only (NSCLO), nonsyndromic cleft lip with palate (NSCLP), and nonsyndromic cleft palate only (NSCPO). However, the genetic architecture underlying NSCPO is largely unknown. Here we performed a 2-stage genome-wide association study (GWAS) on NSCPO and replication analyses of selected variants in other NSOFCs from the Chinese Han population. We identified a novel locus (15q24.3) and a known locus (1q32.2) where variants in or near the gene reached genome-wide significance (2.80 × 10-13 < P < 1.72 × 10-08) in a test for association with NSCPO in a case-control design. Although a variant from 15q24.3 was found to be significantly associated with both NSCPO and NSCLP, the direction of estimated effects on risk were opposite. Our functional annotation of the risk alleles within 15q24.3 coupled with previously established roles of the candidate genes within identified risk loci in periderm development, embryonic patterning, and/or regulation of cellular processes supports their involvement in palate development and the pathogenesis of cleft palate. Our study advances the understanding of the genetic basis of NSOFCs and provides novel insights into the pathogenesis of NSCPO.

Abstract
The host gut colonized enormous microbial community, which can be influenced by diet, diseases, behavior, age, gender, hereditary effects, and environmental factors. However, the relationship between gut microbiota and host genetic variation has not yet been elucidated. In this study, we chose five pheasant lineages—Ring-necked pheasant (RN), Manchurian pheasant (MX), Phasianus versicolor (PV), Shenhong pheasant (SP), and Melanistic mutant pheasant (MM)—to investigate the gut microbial composition of pheasants and its relationship with host genetic variation. Microbial classifications revealed 29 phyla and 241 genera presented in pheasants, with the dominant phylum of Firmicutes and the genus of Lactobacillus. Statistical analyses suggest that the relative abundance of 75 genera was significantly different among the five lineages. The most abundant genus carried by the RN and MM was Streptococcus, which was significantly lower in PV (p = 0.024). Conversely, Lactobacillus was the major genera in PV and MX. Moreover, the RN had the greatest microbial abundance, with a remarkably different microbial community than PV. The gut microbial diversity of PV was the lowest and diverged significantly from the RN and MX. Interestingly, the clustering of the MM and SP in the microbial dendrogram corresponded to their cluster in the host phylogeny. The host phylogenetic split of the RN, MX, and PV echoed their microbial distance. In conclusion, the congruence of host phylogeny and their gut microbial dendrograms implies that gut microbiota of pheasant lineages could reflect their host genetic variation.

Abstract
Mammalian neonates obtain antibodies, nutrients, and microbiota from breast milk that help them resist the complex growth environment. Similar to mammals' lactation behavior for their offspring, parent pigeons regurgitate pigeon milk (PM) from their crops to feed the squabs. Whether pigeon milk is as valuable as mammalian milk is not clear, especially in terms of microbiota. This study adopted 16S rRNA gene sequencing to investigate the microbial composition and function in pigeon milk. We found abundant microbiota in pigeon milk. The dominant genera in parent pigeons' milk were Lactobacillus, Enterococcus, Veillonella, and Bifidobacterium. An analysis of squab milk (SM) showed that Lactobacillus also accounted for a considerable proportion, followed by Bifidobacterium. Most of the squab milk microbial genera were also detected in parent pigeons. Microbial functional analysis showed that the squab milk microbes were more involved in the pathways of carbohydrate metabolism, amino acid metabolism, and energy metabolism. These findings indicated that microbiota play an important role in squabs and can be transmitted from parent pigeons to squabs by pigeon milk. The presence of plentiful probiotics in squabs also suggests that adding probiotics in artificial pigeon milk may promote the growth and development of squabs and improve the production performance of pigeons.

Abstract
Background With the aging of the population, prostate hyperplasia is more and more perplexing to the old men. This study aimed to evaluate the predictive value of international prostatic symptom score-voiding/storage score ratio (IPSS-V/S), urodynamic examination, intravesical prostatic protrusion (IPP) and residual urine volume (RUV) on the efficacy of holmium laser enucleation of the prostate (HoLEP) before operation. Methods Ninety-six patients with benign prostatic hyperplasia (BPH) were enrolled in this study. Each patient was diagnosed as BPH and completed all the evaluations as described above before the same urologist surgeon performed HoLEP. Three months later, another IPSS questionnaire would be finished by each patient to assess the efficacy of the operation. According to the results of IPSS after operation, the group with significant effect and the group with poor effect were divided. Then compare the difference of preoperative examination results between the two groups. Results In single factor analysis, the differences of the age, voiding symptom score, V/S, RUV, Qmax and IPP between the two groups were statistically significant (P<0.05). While there was no significant difference in IPSS score and score of urine storage period. In the logistic regression analysis, the age of patients, V/S, RUV, IPP and Qmax can establish a good prediction model. In this model, the younger the patients are, the less the RUV is, the larger the V/S and IPP are, the more likely they are to achieve good efficacy of HoLEP. Conclusions In conclusion, HoLEP was more effective in BPH patients with younger age, more IPP, less RUV, less Qmax and those whose IPSS score was mainly based on voiding symptoms.

Abstract
Lipid species possess very different structures, leading to their very diversified cellular functions in biological systems. Lipidomics represents a powerful technology for deep analysis of hundreds to thousands of intact lipid molecular species. In the current study, a cluster of unknown ion peaks was displayed when we profiled cerebroside species in rat spinal cord samples by neutral loss scan of 162 Da in the positive ion mode using a multi-dimensional mass spectrometry-based shotgun lipidomics strategy. In order to identify the structural identities of these unknown ion peaks, MS2 and MS3 analyses of these ions were performed by high mass resolution mass spectrometry. Extensive lines of evidence allowed us to identify that these unknown ion peaks were monohexosyl alkyl-acyl glycerol (HAAG) species, including their sn-positional isomers and alkyl-acyl compositional isomers. We also applied the developed method to identify and quantify HAAG species present in a variety of mouse nerve tissues. We believe that the first kind of lipidomics study on HAAG species present in mammalian nerve tissue samples provided the foundation for future biological research in this unknown area.

Abstract
Fiber optic gyroscope (FOG) is one of the important components of Inertial Navigation Systems (INS). In order to improve the accuracy of the INS, it is necessary to suppress the random error of the FOG signal. In this paper, a variational mode decomposition (VMD) denoising method based on beetle swarm antenna search (BSAS) algorithm is proposed to reduce the noise in FOG signal. Firstly, the BSAS algorithm is introduced in detail. Then, the permutation entropy of the band-limited intrinsic mode functions (BLIMFs) is taken as the optimization index, and two key parameters of VMD algorithm, including decomposition mode number K and quadratic penalty factor α , are optimized by using the BSAS algorithm. Next, a new method based on Hausdorff distance (HD) between the probability density function (PDF) of all BLIMFs and that of the original signal is proposed in this paper to determine the relevant modes. Finally, the selected BLIMF components are reconstructed to get the denoised signal. In addition, the simulation results show that the proposed scheme is better than the existing schemes in terms of noise reduction performance. Two experiments further demonstrate the priority of the proposed scheme in the FOG noise reduction compared with other schemes.

Abstract
Polycyclic aromatic hydrocarbon (PAH)-DNA binding is an essential step in PAH-induced carcinogenesis. A large number of PAHs contain substituents, it is unclear whether functional groups will influence the PAH-DNA binding. Here, we investigated amino (-NH2) and hydroxy (-OH) substitution on pyrene-DNA binding. Because of the considerable effects of electrostatic surface potential (ESP), -NH2 substitution significantly facilitated binding by increasing the binding constant (log KA) from 4.14 L mol-1 to 12.31 L mol-1, while -OH substitution inhibited binding by reducing log KA to 3.68 L mol-1. Spectroscopy results revealed that pyrene and its derivatives were able to bind with thymine to induce DNA damage or double helix distortion. Quantum chemical calculations showed that -NH2 substitution induces hydrogen bond formation, thereby enhancing the binding of pyrene with DNA; moreover, binding force changes due to -OH substitution may not be an essential factor. All structural descriptors were not correlated with the quenching constant (KSV) or binding constant, indicating that changes in physicochemical properties shows no influence on pyrene-DNA binding. The results of this study will improve our understanding of the contribution of functional groups to PAH-DNA binding.

Abstract
Growing evidence indicates that aberrant expression of microRNAs (miRNAs) contributes to tumorigenesis in various human malignancies. In this study we revealed that miR-195 acted as a tumor suppressor in renal cell carcinoma (RCC) through inhibition of HMGA1 expression. qRT-PCR was used to detect the miR-195 expression in RCC tissues and cell lines. RCC cell line Caki-1 and Caki-2 cells were used in this study. The luciferase report assay and rescue assay were performed to identify HMGA1 as the target gene of miR-195. Additionally, Kaplan-Meier method and log-rank test was used to explore the relationship between HMGA1 expression and RCC prognosis. We observed that miR-195 expression was significantly downregulated both in RCC tissues and in RCC cell lines. We observed that miR-195 overexpression inhibits the abilities of RCC cell proliferation, cell cycle progression and metastasis in vitro by targeting HMGA1 via epithelial to mesenchymal transition (EMT) pathway. In clinical specimens, HMGA1 was overexpressed in high-grade RCC when compared with its levels in normal tissues and low-grade RCC cancer, its expression levels were inversely correlated with overall survival. Our findings highlight an important role of miR-195 and HMGA1 in the molecular etiology of RCC, indicating that they can serve as potential biomarkers and therapy targets of RCC.

AIM Exosome-derived microRNAs (miRNAs) are potential diagnostic biomarkers. However, little is known about their effectiveness as diagnostic biomarkers of intracranial aneurysms (IAs). This study aimed to explore miRNA levels in plasma exosomes of patients with IA to identify potential biomarkers that predict the development and progress of IA. METHODS A total of 69 patients with IA and 30 healthy controls (HC) were recruited, among whom 30 had unruptured IA (UA), and 39 had ruptured IA (RA). The miRNA expression profiles of plasma exosomes in 12 IA patients (4 UA and 8 RA) and 4 HC were determined using next-generation sequencing. In addition, significantly differentially expressed miRNAs were further analyzed by Quantitative Real-Time PCR (qRT-PCR) in a validation cohort of 99 subjects. RESULTS From the sequencing analysis, 181 miRNAs were identified to be differently (p<0.05) expressed. Of these, 9 miRNAs were up-regulated, and 20 were down-regulated in patients with UA compared with HC. Also, 21 were up-regulated, and 10 were down-regulated in patients with RA compared with HC. In addition, compared with UA, 92 miRNAs were up-regulated in RA, whereas 29 were down-regulated. Furthermore, qRT-PCR analysis confirmed that miR-145-5p and miR-29a-3p were up-regulated in IA samples. To distinguish IA patients from controls, the area under the receiver operating characteristic curve was 0.791 for miR-29a-3p, while that of miRNA-145-5p was 0.773 in terms of discriminating whether the aneurysm was ruptured. CONCLUSIONS Circulating exosomal miRNAs can serve as biomarkers of the development and progression of IA.

Abstract
The long non-coding RNA (lncRNA) H19 has been demonstrated to play a crucial role in carcinogenesis, including renal cell carcinoma (RCC). However, the impact of genetic variations in H19 gene on RCC has not been investigated before. In the present study, we sought to evaluate whether genetic polymorphisms in H19 are related to the susceptibility and mortality of RCC. We genotyped four widely studied polymorphisms in H19 and assessed their relationship with susceptibility and prognosis of RCC in a case-control study compromising 1,027 cases and 1,094 controls. The functionality of the important polymorphism was further investigated by real-time polymerase chain reaction and luciferase reporter assay. We found that H19 rs2839698 was significantly associated with risk and prognosis of RCC. Compared with the H19 rs2839698 CC genotype, the variant genotypes (CT/TT) were significantly associated with increased risk of RCC (P = 0.023, OR = 1.21; 95% CI = 1.03–1.45). Besides, patients with variant genotypes (CT/TT) were more likely to develop large tumor (P = 0.003, OR = 1.47; 95% CI = 1.16–1.85) and advanced disease (P = 0.010, OR = 1.59; 95% CI = 1.12–2.26); and had a significantly unfavorable overall survival than those with the rs2839698 CC genotype (CT/TT vs. CC: Log-rank P = 0.026, HR = 2.25, 95%CI = 1.07–4.75). Furthermore, the CT/TT genotypes were associated with significantly increased expression of H19 in renal tissue. The luciferase reporter assays revealed the potential effect of rs2839698 variant on the binding of microRNAs to H19. Our results suggest that the H19 rs2839698 variant may be a genetic predictor of susceptibility and mortality of RCC. The risk effects and the functional impact of the variant on H19 still need further validation.

Abstract
Acetylcholine (ACh) is believed to improve plant growth. However, regulation at biochemical and molecular levels is largely unknown. The present study investigated the impact of exogenously applied ACh (10 µm) on growth and chlorophyll metabolism in hydroponically grown Nicotiana benthamiana under salt stress (150 mm NaCl). Salinity reduced root hydraulic conductivity while ACh-treated seedlings exhibited a significant increase, resulting in increased relative water content. Salinity induced a reduction in chlorophyll biosynthetic intermediates, such as protoporphyrin-IX, Mg-photoporphyrin-IX and protochlorophyllide, which were significantly ameliorated in the presence of ACh. This influence of ACh on chlorophyll synthesis was confirmed by up-regulation of HEMA1, CHLH, CAO and POR genes. Gas exchange parameters, i.e. stomatal conductance, internal CO2 concentration and transpiration rate, increased with ACh, thereby alleviating the salinity effects on photosynthesis. In addition, the salinity-induced enhancement of lipid peroxidation declined after ACh treatment through modulation of the activity of the assayed antioxidant enzymes (superoxide dismutase and peroxidase). Importantly, ACh significantly reduced the uptake of Na and increased uptake of K, resulting in a decline in the Na/K ratio. Results of the present study indicate that ACh can be effective in ameliorating NaCl-induced osmotic stress, altering chlorophyll metabolism and thus photosynthesis by maintaining ion homeostasis, hydraulic conductivity and water balance.
