Abstract
Plants initiate specific defense responses by recognizing conserved epitope peptides within the flagellin proteins derived from bacteria. Proteolytic cleavage of epitope peptides from flagellin by plant apoplastic proteases is thought to be crucial for the perception of the epitope by the plant receptor. However, the identity of the plant proteases involved in this process remains unknown. Here, we establish an efficient identification system for the target proteases in Arabidopsis apoplastic fluid; the method employs native two-dimensional electrophoresis followed by an in-gel proteolytic assay using a fluorescence-quenching peptide substrate. We designed a substrate to specifically detect proteolytic activity at the C-terminus of the flg22 epitope in flagellin and identified two plant subtilases, SBT5.2 and SBT1.7, as specific proteases responsible for the C-terminal cleavage of flg22. In the apoplastic fluid of Arabidopsis mutant plants deficient in these two proteases, we observe a decrease in the C-terminal cleavage of the flg22 domain from flagellin, leading to a decrease in the efficiency of flg22 epitope liberation. Consequently, defensive reactive oxygen species (ROS) production is delayed in sbt5.2 sbt1.7 double-mutant leaf disks compared to wild type following flagellin exposure.

Abstract
OBJECTIVE The optimal strategy for difficult-to-treat (D2T) rheumatoid arthritis (RA) has not been identified, and the ultrasound characteristics of D2T RA have not been reported. We investigated the clinical characteristics and factors contributing to the outcome in D2T RA in a multicentre RA ultrasound observational cohort. METHOD We reviewed 307 Japanese patients diagnosed with RA who underwent treatment with biological and targeted synthetic disease-modifying anti-rheumatic drugs (b/tsDMARDs). We compared the differences in patient characteristics between the D2T RA and non-D2T RA groups. We examined the factors contributing to a good response [defined as b/tsDMARD continuation and Clinical Disease Activity Index (CDAI) ≤ 10 at 12 months] in the D2T RA patient group. RESULTS Forty-three patients (14%) were categorized as D2T RA and the remaining 264 (86%) as non-D2T RA at baseline. The grey-scale (GS) score, disease duration, and CDAI at the initiation of treatment were significantly higher in the D2T RA group than in the non-D2T RA group. In contrast, the power Doppler (PD) score was not significantly different between the two groups. Of the 43 D2T RA patients, 20 achieved a good response. The introduction of CTLA4-Ig (n = 5) was significantly associated with a good response in analysis based on inverse probability weighting with propensity score. GS and PD scores at baseline were not significantly associated with therapeutic response at 12 months in D2T RA patients. CONCLUSIONS Patients with D2T RA had high clinical and ultrasound activity and poor responses to treatment with b/tsDMARDs. CTLA4-Ig was associated with a good response at 12 months in D2T RA patients.

Abstract
INTRODUCTION Given the chronic nature of psoriasis (PsO), more studies are needed that directly compare the effectiveness of different biologics over long observation periods. This study compares the effectiveness and durability through 12 months of anti-interleukin (IL)-17A biologics relative to other approved biologics in patients with moderate-to-severe psoriasis in a real-world setting. METHODS The Psoriasis Study of Health Outcomes (PSoHO) is an ongoing 3-year, prospective, non-interventional cohort study of 1981 adults with chronic moderate-to-severe plaque psoriasis initiating or switching to a new biologic. The study compares the effectiveness of anti-IL-17A biologics with other approved biologics and provides pairwise comparisons of seven individual biologics versus ixekizumab. The primary outcome was defined as the proportion of patients who had at least a 90% improvement in Psoriasis Area and Severity Index score (PASI90) and/or a score of 0 or 1 in static Physician Global Assessment (sPGA). Secondary objective comparisons included the proportion of patients who achieved PASI90, PASI100, a Dermatology Life Quality Index (DLQI) score of 0 or 1, and three different actions of durability of treatment response. Unadjusted response rates are presented alongside the primary analysis, which uses frequentist model averaging (FMA) to evaluate the adjusted comparative effectiveness. RESULTS Compared to the other biologics cohort, the anti-IL-17A cohort had a higher response rate (68.0% vs. 65.1%) and significantly higher odds of achieving the primary outcome at month 12. The two cohorts had similar response rates for PASI100 (40.5% and 37.1%) and PASI90 (53.9% and 51.7%) at month 12, with no significant differences between the cohorts in the adjusted analyses. At month 12, the response rates across the individual biologics were 53.5-72.6% for the primary outcome, 27.6-48.3% for PASI100, and 41.7-61.4% for PASI90. CONCLUSIONS These results show the comparative effectiveness of biologics at 6 and 12 months in the real-world setting. TRIAL REGISTRATION ClinicalTrials.gov identifier EUPAS24207.

Arabidopsis ASYMMETRIC LEAVES2 and Nucleolar Factors Are Coordinately Involved in the Perinucleolar Patterning of AS2 Bodies and Leaf Development. Plants (Basel) 2023; 12:3621.

Abstract
Arabidopsis ASYMMETRIC LEAVES2 (AS2) plays a key role in the formation of flat symmetric leaves. AS2 represses the expression of the abaxial gene ETTIN/AUXIN RESPONSE FACTOR3 (ETT/ARF3). AS2 interacts in vitro with the CGCCGC sequence in ETT/ARF3 exon 1. In cells of leaf primordia, AS2 localizes at peripheral regions of the nucleolus as two AS2 bodies, which are partially overlapped with chromocenters that contain condensed 45S ribosomal DNA repeats. AS2 contains the AS2/LOB domain, which consists of three sequences conserved in the AS2/LOB family: the zinc finger (ZF) motif, the ICG sequence including the conserved glycine residue, and the LZL motif. AS2 and the genes NUCLEOLIN1 (NUC1), RNA HELICASE10 (RH10), and ROOT INITIATION DEFECTIVE2 (RID2) that encode nucleolar proteins coordinately act as repressors against the expression of ETT/ARF3. Here, we examined the formation and patterning of AS2 bodies made from as2 mutants with amino acid substitutions in the ZF motif and the ICG sequence in cells of cotyledons and leaf primordia. Our results showed that the amino acid residues next to the cysteine residues in the ZF motif were essential for both the formation of AS2 bodies and the interaction with ETT/ARF3 DNA. The conserved glycine residue in the ICG sequence was required for the formation of AS2 bodies, but not for the DNA interaction. We also examined the effects of nuc1, rh10, and rid2 mutations, which alter the metabolism of rRNA intermediates and the morphology of the nucleolus, and showed that more than two AS2 bodies were observed in the nucleolus and at its periphery. These results suggested that the patterning of AS2 bodies is tightly linked to the morphology and functions of the nucleolus and the development of flat symmetric leaves in plants.

Abstract
Stomatal pores in the plant epidermis open and close to regulate gas exchange between leaves and the atmosphere. Upon light stimulation, the plasma membrane (PM) H+-ATPase is phosphorylated and activated via an intracellular signal transduction pathway in stomatal guard cells, providing a primary driving force for the opening movement. To uncover and manipulate this stomatal opening pathway, we screened a chemical library and identified benzyl isothiocyanate (BITC), a Brassicales-specific metabolite, as a potent stomatal-opening inhibitor that suppresses PM H+-ATPase phosphorylation. We further developed BITC derivatives with multiple isothiocyanate groups (multi-ITCs), which demonstrate inhibitory activity on stomatal opening up to 66 times stronger, as well as a longer duration of the effect and negligible toxicity. The multi-ITC treatment inhibits plant leaf wilting in both short (1.5 h) and long-term (24 h) periods. Our research elucidates the biological function of BITC and its use as an agrochemical that confers drought tolerance on plants by suppressing stomatal opening.

Abstract
Plants retain the ability to generate a pluripotent tissue called callus by dedifferentiating somatic cells. A pluripotent callus can also be artificially induced by culturing explants with hormone mixtures of auxin and cytokinin, and an entire body can then be regenerated from the callus. Here we identified a pluripotency-inducing small compound, PLU, that induces the formation of callus with tissue regeneration potency without the external application of either auxin or cytokinin. The PLU-induced callus expressed several marker genes related to pluripotency acquisition via lateral root initiation processes. PLU-induced callus formation required activation of the auxin signaling pathway though the amount of active auxin was reduced by PLU treatment. RNA-seq analysis and subsequent experiments revealed that Heat Shock Protein 90 (HSP90) mediates a significant part of the PLU-initiated early events. We also showed that HSP90-dependent induction of TRANSPORT INHIBITOR RESPONSE 1, an auxin receptor gene, is required for the callus formation by PLU. Collectively, this study provides a new tool for manipulating and investigating the induction of plant pluripotency from a different angle from the conventional method with the external application of hormone mixtures.

Abstract
The ubiquitin-proteasome system is vital to hormone-mediated developmental and stress responses in plants. Ubiquitin ligases target hormone-specific transcriptional activators (TAs) for degradation, but how TAs are processed by proteasomes remains unknown. We report that in Arabidopsis, the salicylic acid- and ethylene-responsive TAs, NPR1 and EIN3, are relayed from pathway-specific ubiquitin ligases to proteasome-associated HECT-type UPL3/4 ligases. Activity and stability of NPR1 were regulated by sequential action of three ubiquitin ligases, including UPL3/4, while proteasome processing of EIN3 required physical handover between ethylene-responsive SCFEBF2 and UPL3/4 ligases. Consequently, UPL3/4 controlled extensive hormone-induced developmental and stress-responsive transcriptional programs. Thus, our findings identify unknown ubiquitin ligase relays that terminate with proteasome-associated HECT-type ligases, which may be a universal mechanism for processive degradation of proteasome-targeted TAs and other substrates.

Abstract
BACKGROUND Limited data are available on long-term efficacy and safety of biologics in patients with psoriasis and metabolic syndrome (MetS), a common comorbidity. OBJECTIVES This analysis updates tildrakizumab efficacy and safety for up to 5 years in patients with and without MetS. METHODS This was a post hoc analysis of the double-blind, randomized, placebo-controlled, phase 3 reSURFACE 1 (NCT01722331) and reSURFACE 2 (NCT01729754) trials in adult patients with moderate to severe chronic plaque psoriasis. Analyses included data through Week 244 from patients who continuously received tildrakizumab 100 (TIL100) or 200 mg (TIL200) and entered the extension studies, stratified by baseline MetS status. Efficacy was assessed via Psoriasis Area and Severity Index (PASI) scores. Safety was evaluated from exposure-adjusted incidence rates (EAIRs) of treatment-emergent adverse events (TEAEs). RESULTS reSURFACE 1 and reSURFACE 2 analyses included 26 and 44 TIL100-treated patients with MetS, 98 and 167 TIL100-treated patients without MetS, 34 and 30 TIL200-treated patients with MetS, and 111 and 130 TIL200-treated patients without MetS, respectively. There were no clinically relevant differences in PASI 75/90/100 response rates at Week 244 between patients with vs without MetS. The proportion of patients with vs without MetS achieving absolute PASI score <3 at Week 244 was 53.8% vs 69.4% and 77.3% vs 80.8% in reSURFACE 1 and 2, respectively, for TIL100-treated patients and 58.8% vs 72.1% and 63.3% vs 72.3%, respectively, for TIL200-treated patients. In both studies, median reduction from baseline PASI score at all time points in patients with vs without MetS was >83% vs >89% for TIL100 and >85% vs >90% for TIL200. Pooled EAIRs of TEAEs, serious TEAEs, and TEAEs of special interest were similar in patients with and without MetS. CONCLUSIONS Tildrakizumab maintains efficacy and a favorable safety profile over 5 years in patients with psoriasis regardless of MetS status.

Abstract
Cleavage and polyadenylation at the 3' end of the pre-mRNA is essential for mRNA function, by regulating its translatability, stability and translocation to the cytoplasm. Cleavage factor I (CFI) is a multi-subunit component of the pre-mRNA 3' end processing machinery in eukaryotes. Here, we report that plant CFI 25 subunit of CFI plays an important role in maintaining the diversity of the 3' ends of mRNA. The genome of Arabidopsis thaliana (L.) Heynh. contained four genes encoding three putative CFI subunits (AtCFI 25, AtCFI 59 and AtCFI 68), orthologous to the mammalian CFI subunits. There were two CFI 25 paralogs (AtCFI 25a and AtCFI 25b) that shared homology with human CFI 25. Two null alleles of AtCFI 25a displayed smaller rosette leaves, longer stigmatic papilla, smaller anther, earlier flowering and lower fertility compared to wild-type plants. Null alleles of AtCFI 25b, as well as, plants ectopically expressing full-length cDNA of AtCFI 25a, displayed no obvious morphological defects. AtCFI 25a was shown to interact with AtCFI 25b, AtCFI 68 and itself, suggesting various forms of CFI in plants. Furthermore, we show that AtCFI 25a function was essential for maintaining proper diversity of the 3' end lengths of transcripts coding for CFI subunits, suggesting a self-regulation of the CFI machinery in plants. AtCFI 25a was also important to maintain 3' ends for other genes to different extent. Collectively, AtCFI 25a, but not AtCFI 25b, seemed to play important roles during Arabidopsis development by maintaining proper diversity of the 3' UTR lengths.

Abstract
An unknown 61 kDa protein is phosphorylated by abscisic acid (ABA)-activated protein kinase in response to ABA and binds to 14-3-3 protein in a phosphorylation-dependent manner in guard-cell protoplasts (GCPs) from Vicia faba. Subsequently, ABA-dependent phosphorylated proteins were identified as basic helix-loop-helix transcription factors, named ABA-responsive kinase substrates (AKSs) in GCPs from Arabidopsis thaliana. However, whether the 61 kDa protein in Vicia GCPs is an AKS is unclear. We performed immunoprecipitation of ABA-treated Vicia GCPs using anti-14-3-3 protein antibodies and identified several AKS isoforms in V. faba (VfAKSs) by mass spectrometry. The 61 kDa protein was identified as VfAKS1. Phosphoproteomic analysis revealed that VfAKSs are phosphorylated at Ser residues, which are important for 14-3-3 protein binding and monomerisation, in response to ABA in GCPs. Orthologs of AtABCG40, an ABA importer in guard cells, and CHC1, a clathrin heavy chain and a regulator of stomatal movement, also co-immunoprecipitated with 14-3-3 protein from guard cells.

Abstract
Plants tailor immune responses to defend against pathogens with different lifestyles. In this process, antagonism between the immune hormones salicylic acid (SA) and jasmonic acid (JA) optimizes transcriptional signatures specifically to the attacker encountered. Antagonism is controlled by the transcription cofactor NPR1. The indispensable role of NPR1 in activating SA-responsive genes is well understood, but how it functions as a repressor of JA-responsive genes remains unclear. Here, we demonstrate that SA-induced NPR1 is recruited to JA-responsive promoter regions that are co-occupied by a JA-induced transcription complex consisting of the MYC2 activator and MED25 Mediator subunit. In the presence of SA, NPR1 physically associates with JA-induced MYC2 and inhibits transcriptional activation by disrupting its interaction with MED25. Importantly, NPR1-mediated inhibition of MYC2 is a major immune mechanism for suppressing pathogen virulence. Thus, NPR1 orchestrates the immune transcriptome not only by activating SA-responsive genes but also by acting as a corepressor of JA-responsive MYC2.

Abstract
OBJECTIVE This study investigated the effectiveness of treatment with Janus kinase (JAK) inhibitors in rheumatoid arthritis (RA) assessed by ultrasonography (US) activity, and the influence of patient characteristics and previous treatments. METHOD This prospective study assessed 60 treatment initiations among 53 Japanese patients diagnosed with RA who underwent treatment with JAK inhibitors during June 2013 to February 2020. Of the 53 patients, seven patients were enrolled in duplicate because they were treated with two different JAK inhibitors at different periods. For each case, the improvement rate on the power Doppler (PD) score was assessed at 6 month follow-up. Median improvement rate of PD score was used to classify cases as either US responders or non-responders, and patient characteristics were compared between the two groups. RESULTS All indicators of clinical disease activity and US activity showed a significant improvement at 3 months compared with baseline. Although the JAK inhibitor-cycler group and the interleukin-6 (IL-6) inhibitor inadequate response (IR) group tended to show a later improvement for US activity, all indicators of clinical disease activity and US activity showed a significant improvement at 6 months compared with baseline for both groups. Multivariate analysis showed that concomitant methotrexate use and an IR to the previous biologic or targeted-synthetic disease-modifying anti-rheumatic drug (b/tsDMARD) treatment were independently and significantly associated with US responders. CONCLUSION Use of a JAK inhibitor in combination with methotrexate and an absence of IR to any previous b/tsDMARDs demonstrated superior effectiveness for patients with RA.

Abstract
Leguminous plants produce nodules for nitrogen fixation; however, nodule production incurs an energy cost. Therefore, as an adaptive strategy, leguminous plants halt root nodule development when sufficient amounts of nitrogen nutrients, such as nitrate, are present in the environment. Although legume NODULE INCEPTION (NIN)-LIKE PROTEIN (NLP) transcription factors have recently been identified, understanding how nodulation is controlled by nitrate, a fundamental question for nitrate-mediated transcriptional regulation of symbiotic genes, remains elusive. Here, we show that two Lotus japonicus NLPs, NITRATE UNRESPONSIVE SYMBIOSIS 1 (NRSYM1)/LjNLP4 and NRSYM2/LjNLP1, have overlapping functions in the nitrate-induced control of nodulation and act as master regulators for nitrate-dependent gene expression. We further identify candidate target genes of LjNLP4 by combining transcriptome analysis with a DNA affinity purification-seq approach. We then demonstrate that LjNLP4 and LjNIN, a key nodulation-specific regulator and paralog of LjNLP4, have different DNA-binding specificities. Moreover, LjNLP4-LjNIN dimerization underlies LjNLP4-mediated bifunctional transcriptional regulation. These data provide a basic principle for how nitrate controls nodulation through positive and negative regulation of symbiotic genes.

Abstract
Topical therapy is the mainstay of treatment for the majority of patients with psoriasis vulgaris (chronic plaque psoriasis), with combinations of vitamin D analogues and glucocorticoids having been shown to negate many of the negative effects associated with either monocomponent individually. Following the established efficacy of fixed‐dose combination calcipotriol (Cal; 50 µg/g) plus betamethasone dipropionate (BD; 0.5 mg/g) ointment and gel formulations, a novel Cal/BD foam formulation was developed. When applied, Cal/BD foam forms a supersaturated solution on the skin, increasing the penetration and bioavailability of Cal and BD. Early data indicate that this results in improved efficacy outcomes versus Cal/BD ointment, without negatively affecting safety outcomes (such as the incidence/severity of side effects or impacted calcium homeostasis or hypothalamic‐pituitary‐adrenal axis). This article discusses the potency and absorption of fixed‐dose combination Cal/BD foam, as well as the positive early efficacy and safety data associated with its utilisation in the treatment of psoriasis vulgaris.

Abstract
Malate efflux from roots, which is regulated by the transcription factor STOP1 (SENSITIVE-TO-PROTON-RHIZOTOXICITY1) and mediates aluminum-induced expression of ALUMINUM-ACTIVATED-MALATE-TRANSPORTER1 (AtALMT1), is critical for aluminum resistance in Arabidopsis thaliana. Several studies showed that AtALMT1 expression in roots is rapidly observed in response to aluminum; this early induction is an important mechanism to immediately protect roots from aluminum toxicity. Identifying the molecular mechanisms that underlie rapid aluminum resistance responses should lead to a better understanding of plant aluminum sensing and signal transduction mechanisms. In this study, we observed that GFP-tagged STOP1 proteins accumulated in the nucleus soon after aluminum treatment. The rapid aluminum-induced STOP1-nuclear localization and AtALMT1 induction were detected in the presence of a protein synthesis inhibitor, suggesting that post-translational regulation is involved in these events. STOP1 also regulated rapid aluminum-induced expression for other genes that carry a functional/high-affinity STOP1-binding site in their promoter, including STOP2, GLUTAMATE-DEHYDROGENASE1 and 2 (GDH1 and 2). However STOP1 did not regulate Al resistance genes which have no functional STOP1-binding site such as ALUMINUM-SENSITIVE3, suggesting that the binding of STOP1 in the promoter is essential for early induction. Finally, we report that GDH1 and 2 which are targets of STOP1, are novel aluminum-resistance genes in Arabidopsis.

Abstract
Objectives: Using multicentre ultrasound (US) cohort data among patients with rheumatoid arthritis (RA), we aimed to identify baseline factors that permit differentiation between two patient cohorts achieving US remission and clinical remission, and to determine the factors contributing to the discrepancy.Method: We reviewed 248 Japanese patients diagnosed with RA who underwent treatment with biological disease-modifying anti-rheumatic drugs at 13 centres. We performed US assessments of the synovia of 22 joints. We assessed the percentages of patients with clinical remission and US remission, defined as total power Doppler scores of 0 at 12 months.Results: The 87 patients who achieved US remission were divided into a group that achieved both clinical and US remission (n = 53) and a group that achieved US remission only (n = 34). Baseline factors that were significantly and independently associated with clinical remission at 12 months among patients who also achieved US remission included short disease duration, the presence of concomitant methotrexate use, and low patient global assessment score (p < 0.05, p < 0.05, and p < 0.005, respectively).Conclusions: RA patients with baseline high patient global assessment scores and long disease duration at baseline were unlikely to achieve clinical remission even after achieving US remission. Objective joint assessments using US provide additional information of potential importance for the management of RA.

Abstract
Background Significantly more patients with moderate‐to‐severe plaque psoriasis treated with the interleukin (IL)‐17A inhibitor ixekizumab vs. the IL‐23p19 inhibitor guselkumab in the IXORA‐R head‐to‐head trial achieved 100% improvement in Psoriasis Area and Severity Index (PASI 100) at week 12. Objectives To compare skin and nail clearance and patient‐reported outcomes for ixekizumab vs. guselkumab, up to week 24. Methods IXORA‐R enrolled adults with moderate‐to‐severe plaque psoriasis, defined as static Physician’s Global Assessment ≥ 3, PASI ≥ 12 and involved body surface area ≥ 10%. Statistical comparisons were performed using the Cochran–Mantel–Haenszel test stratified by pooled site. Time‐to‐first‐event comparisons were performed using Kaplan–Meier analysis, and P‐values were generated using adjusted log‐rank tests stratified by treatment group. Cumulative days at clinical and patient‐reported responses were compared by ancova. The trial was registered with ClinicalTrials.gov (NCT03573323). Results Of the 1027 patients randomly assigned, 90% completed the trial (465 of 520 ixekizumab and 459 of 507 guselkumab). As early as week 2 and through week 16, more patients on ixekizumab achieved PASI 100 (P < 0·01). At week 24, ixekizumab was noninferior to guselkumab (50% vs. 52%, difference −2·3%), with no statistically significant difference in PASI 100 (P = 0·41). More patients receiving ixekizumab showed completely clear nails at week 24 (52% vs. 31%, P = 0·007). The median time to first PASI 50/75/90 and PASI 100 were 2 and 7·5 weeks shorter, respectively, for patients on ixekizumab vs. guselkumab (P < 0·001). Patients on ixekizumab also had a greater cumulative benefit, with more days at PASI 90 and 100, with Dermatology Life Quality Index of 0 or 1, and itch free (P < 0·05). The frequency of serious adverse events was 3% for each group, with no new safety signals. Conclusions Ixekizumab was noninferior to guselkumab in complete skin clearance and superior in clearing nails at week 24. Ixekizumab cleared skin more rapidly in patients with moderate‐to‐severe plaque psoriasis, with a greater cumulative benefit, than guselkumab. Overall, the safety findings were consistent with the known safety profile for ixekizumab. What is already known about this topic?Patients with plaque psoriasis desire both high levels of clearance and rapid onset of treatment effects. Ixekizumab is a high‐affinity monoclonal antibody that selectively targets interleukin (IL)‐17A. In the 12‐week report of the IXORA‐R study, ixekizumab demonstrated significantly higher efficacy at early timepoints than the IL‐23p19 inhibitor guselkumab, with more patients achieving 100% improvement in Psoriasis Area and Severity Index (PASI 100) and improved quality of life as early as week 4.
What does this study add?Patients on ixekizumab vs. guselkumab achieved similar levels of skin clearance and superior efficacy in the resolution of nail psoriasis at week 24. Patients on ixekizumab vs. guselkumab had a greater cumulative benefit, with more days at PASI 90 and 100, more days when psoriasis did not impact their quality of life, and more itch‐free days. The safety profiles of both drugs were consistent with those in previous studies.

Abstract
Objective: To determine whether the positivity of baseline anti-Ro/Sjögren's syndrome antigen A (SSA) antibodies influences the response to abatacept, we compared therapeutic responses between anti-Ro/SSA antibody-negative and -positive patients with rheumatoid arthritis (RA) using a multicentre RA ultrasonography prospective cohort. Method: We reviewed Japanese patients with RA who started abatacept as the first biological disease-modifying anti-rheumatic drug between June 2013 and April 2018. We assessed 28-joint Disease Activity Score-erythrocyte sedimentation rate (DAS28-ESR) change between baseline and 6 or 12 months after treatment in RA patients treated with abatacept, and European League Against Rheumatism (EULAR) response at 6 and 12 months. The Global OMERACT-EULAR Synovitis Score (GLOESS) was calculated at baseline and at 6 and 12 months. Results: Overall, 51 patients were enrolled and divided into anti-Ro/SSA antibody-negative and -positive groups of 35 and 16, respectively. Median age at baseline was significantly higher in the anti-Ro/SSA antibody-negative group (p = 0.04). The retention rate and percentage of EULAR good responders at 12 months were significantly higher in the anti-Ro/SSA antibody-negative group (both p = 0.02). Anti-Ro/SSA antibody-negative patients exhibited larger decreases in both DAS28-ESR and DAS28-C-reactive protein at 12 months than anti-Ro/SSA antibody-positive patients (p = 0.02 and 0.04, respectively). GLOESS decreased significantly at 6 months in anti-Ro/SSA antibody-negative patients (p = 0.03). Multivariate analyses showed that anti-Ro/SSA antibody positivity was an independent factor associated with change in the DAS28-ESR at 6 months (p < 0.05). Conclusion: Anti-Ro/SSA antibody positivity predicts a poor response to abatacept and low retention rate.

Abstract
BACKGROUND Salivary duct carcinoma (SDC) is an aggressive subtype of salivary gland cancer. Approximately half of SDC patients will develop recurrences or metastases. Therapeutic palliative therapy is therefore often needed. The majority of SDC tumors expresses the androgen receptor (AR) and one-third expresses human epidermal growth factor receptor 2 (HER2), both are potential therapeutic targets. The aim of this paper is to systematically review and summarize the evidence on systemic palliative therapy for SDC and to provide treatment recommendations. MATERIALS AND METHODS Electronic libraries were systematically searched with a broad search strategy to identify studies where SDC patients received systemic therapy. Due to the rarity of SDC no restrictions were placed on study designs. RESULTS The search resulted in 2014 articles of which 153 were full-text analyzed. Forty-five studies were included in the analysis, which included in total 256 SDC patients receiving systemic therapy. Two phase 2 trials primarily including SDC patients were identified. The majority of the studies were case series or case reports, resulting in an overall low quality of available evidence. Based on studies including ≥ 5 SDC patients, objective responses to HER2 targeting agents were observed in 60-70%, to AR pathway agents in 18-53% and to chemotherapy in 10-50%. CONCLUSION For AR or HER2 positive SDC, agents targeting these pathways are the cornerstone for palliative treatment. Regarding chemotherapy, the combination of carboplatin combined with a taxane is best studied. Regarding other targeted agents and immunotherapy evidence is anecdotal, limiting formulation of treatment recommendations for these antineoplastic agents.

Abstract
BACKGROUND Patients with psoriasis value rapid and complete skin clearance. No head-to-head studies have focused on early responses to interleukin (IL)-17 vs. IL-23 inhibitors. OBJECTIVES To compare early and complete skin clearance by the IL-17A inhibitor ixekizumab vs. the IL-23p19 inhibitor guselkumab. METHODS IXORA-R, a 24-week, randomized, double-blinded study, enrolled adults with moderate-to-severe plaque psoriasis [static Physician's Global Assessment of Disease (sPGA) score of ≥ 3, Psoriasis Area and Severity Index (PASI) ≥ 12, and ≥ 10% body surface area]. Patients were randomized (1 : 1) to receive the approved dose of subcutaneous ixekizumab or guselkumab. Primary end point was 100% improvement in PASI (PASI 100) at week 12. Major secondary end points included other levels of improved PASI and sPGA at different time points. Comparisons were made using the Cochran-Mantel-Haenszel test with a multiple testing strategy. Nonresponder imputation was used for missing data. After the completion of the study, the final secondary end point (PASI 100 at 24 weeks) and safety data through week 24 will be reported. RESULTS In total, 1027 patients were randomized. The primary end point PASI 100 at week 12 was met [215/520 ixekizumab (41%); 126/507 guselkumab (25%); P < 0·001]. All major secondary end points measured up to week 12 were met, including PASI 50 at week 1 and PASI 75 at week 2. Serious adverse event frequency was 3% for each group; no new safety signals were identified. CONCLUSIONS Ixekizumab was superior to guselkumab for rapidly improving signs and symptoms in patients with moderate-to-severe plaque psoriasis by week 12. Adverse events were similar to previous ixekizumab and guselkumab studies. Compared with the IL-23 inhibitor guselkumab, ixekizumab can offer complete skin clearance more rapidly to patients with moderate-to-severe plaque psoriasis. What's already known about this topic? Patients with plaque psoriasis desire both high levels of clearance and rapid onset of treatment effects. Ixekizumab, a high-affinity monoclonal antibody that selectively targets interleukin (IL)-17A, has demonstrated greater and faster skin clearance than etanercept and ustekinumab, with consistent long-term efficacy, safety and durability of response. Clinical trial data and systematic reviews have suggested that IL-17 inhibitors can improve a patient's psoriasis more rapidly than IL-23 inhibitors. What does this study add? The head-to-head study design directly compares the efficacy and speed of response of ixekizumab and the IL-23 inhibitor guselkumab in moderate-to-severe plaque psoriasis. The primary end point was met, showing superiority of ixekizumab over guselkumab for achieving complete skin clearance at week 12. The safety profile of ixekizumab was consistent with previous studies. Ixekizumab can deliver patients complete skin clearance and improved quality of life more rapidly than guselkumab.

Abstract
BACKGROUND The metastatic involvement of regional lymph nodes is the most important prognostic factor for overall survival of skin cancer patients. The sonographic technique of freehand real-time tissue elastography (RTE), which displays tissue rigidity as a colour overlay of the tissue image, was developed. OBJECTIVE Our purpose was to evaluate the benefit of RTE for detecting lymph node metastases of skin cancer non-invasively before operation. METHODS We first selected lymph nodes of skin cancer patients which had already been diagnosed by biopsy as being reactive or metastatic, and then retrospectively collected images of RTE and B-mode and colour Doppler ultrasound on those lymph nodes performed preoperatively. Twenty-one lymph nodes from 12 patients with squamous cell carcinoma (SCC), 23 lymph nodes from 14 patients with malignant melanoma (MM) and 14 lymph nodes from six patients with extramammary Paget disease (Paget) were investigated. Elastographic images were assessed on a scale of one to four according to the percentage of high elasticity (hard) area (HEA) in the lymph node. RESULTS In all three skin cancers, lymph nodes evaluated as grade 3 or 4 by RTE were metastatic. All lymph nodes evaluated as grade 1 or 2 by RTE were reactive in SCC, whereas some lymph nodes evaluated as grade 1 or 2 were metastatic in MM and Paget. CONCLUSION Real-time tissue elastography may aid in distinguishing reactive lymph nodes from metastatic ones especially in SCC.

Abstract
Homologous recombination is a key process for maintaining genome integrity and diversity. In eukaryotes, the nucleosome structure of chromatin inhibits the progression of homologous recombination. The DNA repair and recombination protein RAD54 alters the chromatin structure via nucleosome sliding to enable homology searches. For homologous recombination to progress, appropriate recruitment and dissociation of RAD54 is required at the site of homologous recombination; however, little is known about the mechanism regulating RAD54 dynamics in chromatin. Here, we reveal that the histone demethylase LYSINE-SPECIFIC DEMETHYLASE1-LIKE 1 (LDL1) regulates the dissociation of RAD54 at damaged sites during homologous recombination repair in the somatic cells of Arabidopsis (Arabidopsis thaliana). Depletion of LDL1 leads to an overaccumulation of RAD54 at damaged sites with DNA double-strand breaks. Moreover, RAD54 accumulates at damaged sites by recognizing histone H3 Lys 4 di-methylation (H3K4me2); the frequency of the interaction between RAD54 and H3K4me2 increased in the ldl1 mutant with DNA double-strand breaks. We propose that LDL1 removes RAD54 at damaged sites by demethylating H3K4me2 during homologous recombination repair and thereby maintains genome stability in Arabidopsis.

Abstract
Abstract
Background
Hematopoietic stem cell transplantation (HSCT) has been established as a treatment of various hematologic malignancies and improved their prognoses. HSCT includes intensive chemotherapy and systemic radiation, which occasionally induces cardiac dysfunction. However, early predictor of cardiac dysfunction associated with HSCT is still elusive. Recently, left ventricular (LV) global longitudinal strain (GLS) has been recognized as an early detector of cardiotoxicity. In this study, we retrospectively analyzed GLS and cardiac parameters in patients with hematologic malignancies before and after HSCT to explore HSCT-induced cardiac dysfunction.
Methods
Thirty-one consecutive patients undergone HSCT were enrolled and reviewed their cardiac comorbidities, medications, chemotherapy, and radiotherapy before HSCT. Transthoracic echocardiographic variables including GLS, cardiac troponin-I, and B-type natriuretic peptide were analyzed prior to and 1 month after HSCT.
Results
The patients were 49.7±13.5 years of age, 61% were male, and 52% had cardiovascular risk factors. Cardiac troponin-I was significantly increased following HSCT from 0.010±0.002 ng/ml to 0.016±0.014 ng/ml (P=0.02), indicating that HSCT should have certain impact on cardiac myocytes. Echocardiographic analyses revealed that LV GLS was significantly decreased after HSCT from −19.4±0.8% to −18.8±0.8% (P<0.001), whereas there was no significant difference in LV ejection fraction between these time points of HSCT (63.6±5.5% vs. 64.7±4.6%; P=0.13). Although there was no correlation between the decline of GLS and the increase of troponin-I in this cohort, these results clearly indicated that GLS, but not LVEF, predicted HSCT-induced early and subclinical cardiac dysfunction at 1 month after the HSCT.
Conclusion
GLS detected early decline of cardiac function after HSCT in the patients with hematologic malignancies. Further follow-up investigations will reveal relationship between GLS, troponin-I and prognosis of cardiac function after HSCT in patients with hematologic malignancies.

Abstract
Hydrogen peroxide (H2O2) is a common signal molecule initiating transcriptional responses to all the known biotic and abiotic stresses of land plants. However, the degree of involvement of H2O2 in these stress responses has not yet been well studied. Here we identify time-dependent transcriptome profiles stimulated by H2O2 application in Arabidopsis (Arabidopsis thaliana) seedlings. Promoter prediction based on transcriptome data suggests strong crosstalk among high light, heat, and wounding stress responses in terms of environmental stresses and between the abscisic acid (ABA) and salicylic acid (SA) responses in terms of phytohormone signaling. Quantitative analysis revealed that ABA accumulation is induced by H2O2 but SA is not, suggesting that the implied crosstalk with ABA is achieved through ABA accumulation while the crosstalk with SA is different. We identified potential direct regulatory pairs between regulator transcription factor (TF) proteins and their regulated TF genes based on the time-course transcriptome analysis for the H2O2 response, in vivo regulation of the regulated TF by the regulator TF identified by expression analysis of mutants and overexpressors, and in vitro binding of the regulator TF protein to the target TF promoter. These analyses enabled the establishment of part of the transcriptional regulatory network for the H2O2 response composed of 15 regulatory pairs of TFs, including five pairs previously reported. This regulatory network is suggested to be involved in a wide range of biotic and abiotic stress responses in Arabidopsis.

Abstract
Brassinosteroids (BRs) are steroid phytohormones that regulate plant growth and development, and promote cell elongation at least in part via the acid-growth process. BRs have been suggested to induce cell elongation by the activating plasma membrane (PM) H+-ATPase. However, the mechanism by which BRs activate PM H+-ATPase has not been clarified. In this study, we investigated the effects of BR on hypocotyl elongation and the phosphorylation status of a penultimate residue, threonine, of PM H+-ATPase, which affects the activation, in the etiolated seedlings of Arabidopsis thaliana. Brassinolide (BL), an active endogenous BR, induced hypocotyl elongation, phosphorylation of the penultimate, threonine residue of PM H+-ATPase, and binding of the 14-3-3 protein to PM H+-ATPase in the endogenous BR-depleted seedlings. Changes in both BL-induced elongation and phosphorylation of PM H+-ATPase showed similar concentration dependency. BL did not induce phosphorylation of PM H+-ATPase in the BR receptor mutant bri1-6. In contrast, bikinin, a specific inhibitor of BIN2 that acts as a negative regulator of BR signaling, induced its phosphorylation. Furthermore, BL accumulated the transcripts of SMALL AUXIN UP RNA 9 (SAUR9) and SAUR19, which suppress dephosphorylation of the PM H+-ATPase penultimate residue by inhibiting D-clade type 2C protein phosphatase in the hypocotyls of etiolated seedlings. From these results, we conclude that BL-induced phosphorylation of PM H+-ATPase penultimate residue is mediated via the BRI1-BIN2 signaling pathway, together with the accumulation of SAURs during hypocotyl elongation.

Abstract
Biotic and abiotic stimuli induce profound transcriptional reprograming in plants through sophisticated regulation of transcription factors (TFs). Recombinant proteins of TFs play an important role in unveiling their molecular functions. Cell-free protein synthesis (CFPS) system from wheat germ has been developed as one of the most efficient protein synthesis platforms. However, preparation of linear DNA templates for in vitro transcription is time-consuming and laborious. Here, we describe a versatile method for in vitro transcription and translation of the wheat germ CFPS system. Our two-step PCR method enables researchers to generate a variety of transcription templates from a single plasmid including fusion proteins of an N- or C-terminal tag and truncated proteins. Thus, this method supports a rapid and high-throughput expression of proteins for a large-scale proteomics analysis.

Abstract
Identification of specific DNA binding sites of transcription factors is important in understanding their functions. Recent techniques allow us to investigate genome-wide in vivo binding positions by chromatin immunoprecipitation combined with high-throughput sequencing. However, to further explore the binding motifs of transcription factors, in-depth biochemical analysis is required. Here, we describe an efficient protocol of protein-DNA interactions based on a combination of our in vitro transcription/translation system and AlphaScreen® technology. The in vitro transcription/translation system supports an efficient and quick way of protein synthesis by alleviating cumbersome cloning steps. In addition, AlphaScreen® system provides a highly sensitive, quick, and easy handling platform to investigate the protein-DNA interactions in vitro. Thus, our method largely contributes to comprehensive analysis of the biochemical properties of transcription factors.

Abstract
Regulated degradation of proteins by the 26S proteasome plays important roles in maintenance and signalling in eukaryotic cells. Proteins are marked for degradation by the action of E3 ligases that site-specifically modify their substrates by adding chains of ubiquitin. Innate immune signalling in plants is deeply reliant on the ubiquitin-26S proteasome system. While progress has been made in understanding substrate ubiquitination during plant immunity, how these substrates are processed upon arrival at the proteasome remains unclear. Here we show that specific members of the HECT domain-containing family of ubiquitin protein ligases (UPL) play important roles in proteasomal substrate processing during plant immunity. Mutations in UPL1, UPL3 and UPL5 significantly diminished immune responses activated by the immune hormone salicylic acid (SA). In depth analyses of upl3 mutants indicated that these plants were impaired in reprogramming of nearly the entire SA-induced transcriptome and failed to establish immunity against a hemi-biotrophic pathogen. UPL3 was found to physically interact with the regulatory particle of the proteasome and with other ubiquitin-26S proteasome pathway components. In agreement, we demonstrate that UPL3 enabled proteasomes to form polyubiquitin chains, thereby regulating total cellular polyubiquitination levels. Taken together, our findings suggest that proteasome-associated ubiquitin ligase activity of UPL3 promotes proteasomal processivity and is indispensable for development of plant immunity.

Abstract
Auxin regulates diverse aspects of plant growth and development through induction of the interaction between TRANSPORT INHIBITOR RESPONSE 1/AUXIN SIGNALING F-BOX proteins (TIR1/AFBs) and AUXIN/INDOLE-3-ACETIC ACID (Aux/IAA) co-receptor proteins and the subsequent transcriptional regulation. The artificial control of endogenous auxin signaling should enable the precise delineation of auxin-mediated biological events as well as the agricultural application of auxin. To this end, we previously developed a synthetic auxin-receptor pair that consists of 5-(3-methoxyphenyl)-IAA (convexIAA, cvxIAA) and the engineered TIR1 whose phenylalanine at position 79 in the auxin-binding pocket is substituted to glycine (TIR1F79G) (concaveTIR1, ccvTIR1). This synthetic auxin-receptor pair works orthogonally to natural auxin signaling in transgenic plants harboring the engineered TIR1 by exogenous application of 5-(3-methoxyphenyl)-IAA, and has potential to be utilized as novel agricultural/horticultural tools. In the present study, we report an improved version of the synthetic cvxIAA-ccvTIR1 pair such that synthetic IAA can act at lower concentrations. Using a yeast two-hybrid system, we screened various 5-substituted IAAs and identified 5-adamantyl-IAA, named pico_cvxIAA, which mediates interaction of TIR1F79G and IAA3 proteins at a 1,000-fold lower concentration than the original version, 5-(3-methoxyphenyl)-IAA. Furthermore, we found that TIR1F79A interacts with IAA3 protein in the presence of picomolar concentrations of 5-adamantyl-IAA, 10,000-fold lower than our prototype version of the cvxIAA-ccvTIR1 pair. In addition, pull-down assays confirmed that 5-adamantyl-IAA mediates in vitro interaction of TIR1F79A and IAA7-DII peptides at lower concentrations. The improved synthetic IAA-TIR1 pair with high affinity would be beneficial for basic science as well as for practical use in agriculture/horticulture.

Abstract
Arabidopsis ASYMMETRIC LEAVES2 (AS2) plays a critical role in leaf adaxial-abaxial partitioning by repressing expression of the abaxial-determining gene ETTIN/AUXIN RESPONSE FACTOR3 (ETT/ARF3). We previously reported that six CpG dinucleotides in its exon 6 are thoroughly methylated by METHYLTRASFERASE1, that CpG methylation levels are inversely correlated with ETT/ARF3 transcript levels and that methylation levels at three out of the six CpG dinucleotides are decreased in as2-1. All these imply that AS2 is involved in epigenetic repression of ETT/ARF3 by gene body DNA methylation. The mechanism of the epigenetic repression by AS2, however, is unknown. Here, we tested mutations of NUCLEOLIN1 (NUC1) and RNA HELICASE10 (RH10) encoding nucleolus-localized proteins for the methylation in exon 6 as these mutations enhance the level of ETT/ARF3 transcripts in as2-1. Methylation levels at three specific CpGs were decreased in rh10-1, and two of those three overlapped with those in as2-1. Methylation levels at two specific CpGs were decreased in nuc1-1, and one of those three overlapped with that in as2-1. No site was affected by both rh10-1 and nuc1-1. One specific CpG was unaffected by these mutations. These results imply that the way in which RH10, NUC1 and AS2 are involved in maintaining methylation at five CpGs in exon 6 might be through at least several independent pathways, which might interact with each other. Furthermore, we found that AS2 binds specifically the sequence containing CpGs in exon 1 of ETT/ARF3, and that the binding requires the zinc-finger-like motif in AS2 that is structurally similar to the zinc finger-CxxC domain in vertebrate DNA methyltransferase1.

Abstract
BACKGROUND The efficacy and safety of naldemedine (a peripherally acting µ-opioid receptor antagonist) for opioid-induced constipation (OIC) in subjects with cancer was demonstrated in the primary report of a phase III, double-blind study (COMPOSE-4) and its open-label extension (COMPOSE-5). The primary end point, the proportion of spontaneous bowel movement (SBM) responders, was met. Here, we report results from secondary end points, including quality of life (QOL) assessments from these studies. PATIENTS AND METHODS In COMPOSE-4, eligible adults with OIC and cancer were randomly assigned 1:1 to receive once-daily oral naldemedine 0.2 mg (n = 97) or placebo (n = 96) for 2 weeks, and those who continued on to COMPOSE-5 received naldemedine for 12 weeks (n = 131). Secondary assessments in COMPOSE-4 included the proportion of complete SBM (CSBM) responders, SBM or CSBM responders by week, and subjects with ≥1 SBM or CSBM within 24 h postinitial dose. Changes from baseline in the frequency of SBMs or CSBMs per week were assessed at weeks 1 and 2. Time to the first SBM or CSBM postinitial dose was also evaluated. In both studies, QOL impact was evaluated by Patient Assessment of Constipation-Symptoms (PAC-SYM) and PAC-QOL questionnaires. RESULTS Naldemedine improved bowel function for all secondary efficacy assessments versus placebo (all P ≤ 0.0002). The timely onset of naldemedine activity versus placebo was evidenced by median time to the first SBM (4.7 h versus 26.6 h) and CSBM (24.0 h versus 218.5 h) postinitial dose (all P < 0.0001). In COMPOSE-4, significant differences between groups were observed with the PAC-SYM stool domain (P = 0.045) and PAC-QOL dissatisfaction domain (P = 0.015). In COMPOSE-5, significant improvements from baseline were observed for overall and individual domain scores of PAC-SYM and PAC-QOL. CONCLUSIONS Naldemedine provided effective and timely symptomatic relief from OIC and improved the QOL of subjects with OIC and cancer.
