cted using the Viral Gene-spin™ Viral DNA/RNA Extraction Kit (iNtRON Biotechnology, Seongnam, Korea). Two primer pairs, namely CLBV2-1-F (5'-TCATCCAGAAGGGTATCTCGGA-3')/CLBV2-1-R (5'-CCCTCCTCACCTTCCCCATA-3') and CLBV2-2-F (5'-GGGTCAAGAAGCACGTCAGA-3')/CLBV2-2-R(5'-CGTTCCACATCCATTGAAGGAC-3'), were designed based on the previously assembled sequence (OL871235), and a 588 bp fragment encoding a partial replicase protein and a 780 bp fragment encoding a partial coat protein were successfully amplified from sample #6. The amplification products were cloned into the pGEM-T Easy vector (Promega, Madison, WI, USA), plasmid DNA was isolated and sequenced in both direction by Macrogen Inc. The obtained sequences shared 99.87-100% identity with HTS assembled sequence and 99.15-99.49% identity with CLBV 2 CN-2 (MH558590). However, CLBV 2 was not identified in the remaining 11 samples. To the best of our knowledge, this is the first report of CLBV 2 in Korea in mandarin in mixed infection with CTV and CLBV.Citrus melanose caused by the ascomycete fungus Diaporthe citri is one of the most important diseases in China that not only affects the production, but also impacts the quality of citrus. In China, mancozeb is recommended to control melanose disease at the dose of 1.34 g/L. However, it is widely applied in practice at the dose of 2.66 g/L or even 4 g/L, because reduced efficacy of the recommended dose was observed in the severe melanose damaging regions.In this study, some eco-friendly chemicals for melanose management were evaluated. Firstly, the sensitivity to fungicides was screened in the laboratory based on the inhibition of mycelial growth and conidial germination of D. citri. Results showed that both quinone outside inhibitor fungicides (QoIs) kresoxim-methyl and trifloxystrobin inhibited conidial germination of D. citri up to 100% at 0.1 μg/mL. The in vivo control efficacy on detached fruit indicated that treatments with 2 g/L elastic nano co polymer film, 1 g/L mancozeb and 0.1 g/L kresoxim-methyl significantly inhibited the infection process compared to the control treatment of mineral oil alone. In field trials, the efficacy of 0.1 g/L kresoxim-methyl and 2 g/L elastic nano co polymer film mixed with 1 g/L mancozeb was equal to that of 2.66 g/L mancozeb. The use of mancozeb could be reduced greatly, and the newly developed fungicide combinations are more environmental friendly due to the low toxicity of both QoI fungicides and elastic nano co polymer film. The newly developed method with eco-friendly chemicals should play an important role in the management of citrus melanose in the future.

Antibody-drug conjugates (ADC) are antineoplastic agents recently introduced into the antitumor arsenal. T-DM1, a trastuzumab-based ADC that relies on lysosomal processing to release the payload, is approved for HER2-positive breast cancer. Next-generation ADCs targeting HER2, such as [vic-]trastuzumab duocarmazine (SYD985), bear linkers cleavable by lysosomal proteases and membrane-permeable drugs, mediating a bystander effect by which neighboring antigen-negative cells are eliminated. Many antitumor therapies, like DNA-damaging agents or CDK4/6 inhibitors, can induce senescence, a cellular state characterized by stable cell-cycle arrest. Another hallmark of cellular senescence is the enlargement of the lysosomal compartment. Given the relevance of the lysosome to the mechanism of action of ADCs, we hypothesized that therapies that induce senescence would potentiate the efficacy of HER2-targeting ADCs. Treatment with the DNA-damaging agent doxorubicin and CDK4/6 inhibitor induced lysosomal enlargement and r senescence may improve their therapeutic efficacy by facilitating a bystander effect against antigen-negative tumor cells.Optimization of peptide stability is essential for the development of peptides as bona fide alternatives to approved monoclonal antibodies. This is clearly the case for the many peptides reported to antagonize proprotein convertase subtilisin-like/kexin type 9 (PCSK9), a clinically validated target for lowering cholesterol. However, the effects of optimization of stability on in vivo activity and particularly the effects of binding to albumin, an emerging drug design paradigm, have not been studied for such peptide leads. In this study, we optimized a PCSK9 inhibitory peptide by mutagenesis and then by conjugation to a short lipidated tag to design P9-alb fusion peptides that have strong affinity to human serum albumin. Although attachment of the tag reduced activity against PCSK9, which was more evident in surface plasmon resonance binding and enzyme-linked immunosorbent competition assays than in cellular assays of activity, activity remained in the nanomolar range (∼40 nM). P9-alb peptides were exceptionally stable in human serum and had half-lives exceeding 48 h, correlating with longer half-lives in mice (40.8 min) compared to the unconjugated peptide. Hexadimethrine Bromide nmr Furthermore, the decrease in in vitro binding was not deleterious to in vivo function, showing that engendering albumin binding improved low-density lipoprotein receptor recovery and cholesterol-lowering activity. Indeed, the peptide P9-albN2 achieved similar functional endpoints as the approved anti-PCSK9 antibody evolocumab, albeit at higher doses. Our study illustrates that optimization of stability instead of binding affinity is an effective way to improve in vivo function.

The immunosuppressive tumor microenvironment in some cancer types, such as luminal breast cancer, supports tumor growth and limits therapeutic efficacy. Identifying approaches to induce an immunostimulatory environment could help improve cancer treatment. Here, we demonstrate that inhibition of cancer-intrinsic EZH2 promotes antitumor immunity in estrogen receptor α-positive (ERα+) breast cancer. EZH2 is a component of the polycomb-repressive complex 2 (PRC2) complex, which catalyzes trimethylation of histone H3 at lysine 27 (H3K27me3). A 53-gene PRC2 activity signature was closely associated with the immune responses of ERα+ breast cancer cells. The stimulatory effects of EZH2 inhibition on immune surveillance required specific activation of type I IFN signaling. Integrative analysis of PRC2-repressed genes and genome-wide H3K27me3 landscape revealed that type I IFN ligands are epigenetically silenced by H3K27me3. Notably, the transcription factor STAT2, but not STAT1, mediated the immunostimulatory functions of type I IFN signaling. Following EZH2 inhibition, STAT2 was recruited to the promoters of IFN-stimulated genes even in the absence of the cytokines, suggesting the formation of an autocrine IFN-STAT2 axis. In patients with luminal breast cancer, high levels of EZH2 and low levels of STAT2 were associated with the worst antitumor immune responses. Collectively, this work paves the way for the development of an effective therapeutic strategy that may reverse immunosuppression in cancer.

Inhibition of EZH2 activates a type I IFN-STAT2 signaling axis and provides a therapeutic strategy to stimulate antitumor immunity and therapy responsiveness in immunologically cold luminal breast cancer.

The remarkable biocompatibility and electrochemical performance of polystyrene sulfonate-doped poly(3,4-ethylenedioxythiophene) (PEDOTPSS) have made it the most recommended conductive polymer neural electrode material. However, PEDOTPSS formed by electrochemical deposition, called PEDOT/PSS, often need multiple doping to improve structural instability in moisture, resolve the difficulties of functionalization, and overcome the poor cellular affinity. In this work, inspired by the catechol-derived adhesion and semiconductive properties of polydopamine melanin (PDAM), we used electrochemical oxidation polymerization to develop PDAM-doped PEDOT (PEDOT/PDAM) as a bioactive multimodal neural interface that permits robust electrochemical performance, structural stability, analyte-trapping capacity, and neural stem cell affinity. The use of potentiorecording. With these advantages, PEDOT/PDAM is anticipated to be an efficient bioactive multimodal neural electrode material with potential application to brain-machine interfaces.

The market demand for Panax notoginseng (P. notoginseng) is growing rapidly because of its useful properties in food and medicine. However, the frequent adulteration of P. notoginseng seriously affects the health of consumers and is a great challenge to food safety. In this study, low- and high-field nuclear magnetic resonance (LF/HF-NMR) were applied to detect the transverse relaxation distribution of P. notoginseng contaminated with different ratios of Caulis clematidis armandii (CCA) and the components in P. notoginseng and CCA, respectively.

Fifty-seven kinds of major and minor components in P. notoginseng and CCA were identified and quantified from their high-resolution NMR spectra, and there were significant differences in ginsenosides, sucrose, and glucose between P. notoginseng and CCA. Furthermore, the partial least squares regression analysis results indicated that LF-NMR parameters (T

and S

) changed linearly as the ratio of CCA increased, and these changes were attributed to the variations in polysaccharide and sucrose in adulterated P. notoginseng.

In the relaxation time-based pattern recognition models, the authentic P. notoginseng powder could be classified with 100% accuracy from adulterated P. notoginseng when the adulteration ratio was greater than 30%, demonstrating the possibility of LF-NMR, in combination with pattern recognition, for rapid discrimination of food authenticity. © 2022 Society of Chemical Industry.

Advanced-stage mucinous ovarian carcinoma (MOC) has poor chemotherapy response and prognosis and lacks biomarkers to aid stage I adjuvant treatment. Differentiating primary MOC from gastrointestinal (GI) metastases to the ovary is also challenging due to phenotypic similarities. Clinicopathologic and gene-expression data were analyzed to identify prognostic and diagnostic features.

Discovery analyses selected 19 genes with prognostic/diagnostic potential. Validation was performed through the Ovarian Tumor Tissue Analysis consortium and GI cancer biobanks comprising 604 patients with MOC (n = 333), mucinous borderline ovarian tumors (MBOT, n = 151), and upper GI (n = 65) and lower GI tumors (n = 55).

Infiltrative pattern of invasion was associated with decreased overall survival (OS) within 2 years from diagnosis, compared with expansile pattern in stage I MOC [hazard ratio (HR), 2.77; 95% confidence interval (CI), 1.04-7.41, P = 0.042]. Increased expression of THBS2 and TAGLN was associated with shorter OS in MOC patients (HR, 1.
