Preparation of Multifunctional Nano-Protectants for High-Efficiency Green Control of Anthracnose.

Nanomaterials cannot only act as active ingredients (AIs), but also adjuvants to encapsulate or attach AIs to improve their fungicidal activity. Herein, a hydrophilic and lipophilic diblock polymer (HLDP) is designed and synthesized to prepare a series of HLDP nano-protectants to explore the best HLDP nano-protectant for anthracnose management. These results demonstrate that the HLDP-CS nano-protectant displays the best control effects on mango anthracnose via the direct pathogen inhibition and amplified plant immune responses.

AR coactivators, CBP/p300, are critical mediators of DNA repair in prostate cancer.

Castration resistant prostate cancer (CRPC) remains an incurable disease stage with ineffective treatments options. Here, the androgen receptor (AR) coactivators CBP/p300, which are histone acetyltransferases, were identified as critical mediators of DNA damage repair (DDR) to potentially enhance therapeutic targeting of CRPC. Key findings demonstrate that CBP/p300 expression increases with disease progression and selects for poor prognosis in metastatic disease.

promotes oncogenesis and lethal progression of prostate cancer.

Higher levels of aneuploidy, characterized by imbalanced chromosome numbers, are associated with lethal progression in prostate cancer. However, how aneuploidy contributes to prostate cancer aggressiveness remains poorly understood. In this study, we assessed in patients which genes on chromosome 8q, one of the most frequently gained chromosome arms in prostate tumors, were most strongly associated with long-term risk of cancer progression to metastases and death from prostate cancer (lethal disease) in 403 patients and found the strongest candidate was cohesin subunit gene, , with an odds ratio of 3.

Nucleotide depletion promotes cell fate transitions by inducing DNA replication stress.

Control of cellular identity requires coordination of developmental programs with environmental factors such as nutrient availability, suggesting that perturbing metabolism can alter cell state. Here, we find that nucleotide depletion and DNA replication stress drive differentiation in human and murine normal and transformed hematopoietic systems, including patient-derived acute myeloid leukemia (AML) xenografts. These cell state transitions begin during S phase and are independent of ATR/ATM checkpoint signaling, double-stranded DNA break formation, and changes in cell cycle length.

AmCBF1 activates the expression of GhClpR1 to mediate dark-green leaves in cotton (Gossypium hirsutum).

The transcription factor AmCBF1 deepens the leaf colour of transgenic cotton by binding to the promoter of the chloroplast development-related protein GhClpR1 to promote photosynthesis. The ATP-dependent caseinolytic protease (Clp protease) family plays a crucial role within chloroplasts, comprising several Clp proteins to maintain chloroplast homeostasis. At present, research on Clp proteins mainly focuses on Arabidopsis, leaving its function in other plants, particularly in crops, less explored.

Meiotic protein SYCP2 confers resistance to DNA-damaging agents through R-loop-mediated DNA repair.

Drugs targeting the DNA damage response (DDR) are widely used in cancer therapy, but resistance to these drugs remains a major clinical challenge. Here, we show that SYCP2, a meiotic protein in the synaptonemal complex, is aberrantly and commonly expressed in breast and ovarian cancers and associated with broad resistance to DDR drugs. Mechanistically, SYCP2 enhances the repair of DNA double-strand breaks (DSBs) through transcription-coupled homologous recombination (TC-HR).

Repression of Reduces Plant Height in .

The original 'Green Revolution' genes are associated with gibberellin deficiency. However, in some species, mutations in these genes cause pleiotropic phenotypes, preventing their application in dwarf breeding. The development of novel genotypes with reduced plant height will resolve this problem.

A risk model for the early diagnosis of acute myocardial infarction in patients with chronic kidney disease.

Introduction: Acute myocardial infarction (AMI) remains a critical disease, characterized by a high fatality rate in several countries. In clinical practice, the incidence of AMI is increased in patients with chronic kidney disease (CKD). However, the early diagnosis of AMI in the above group of patients is still poor.

Inhibition of chitin deacetylases to attenuate plant fungal diseases.

Phytopathogenic fungi secrete chitin deacetylase (CDA) to escape the host's immunological defense during infection. Here, we showed that the deacetylation activity of CDA toward chitin is essential for fungal virulence. Five crystal structures of two representative and phylogenetically distant phytopathogenic fungal CDAs, VdPDA1 from Verticillium dahliae and Pst_13661 from Puccinia striiformis f.

Self-Assembled Nanonematicide Induces Adverse Effects on Oxidative Stress, Succinate Dehydrogenase Activity, and ATP Generation.

Long-term overuse of chemical nematicides has resulted in low control efficacy toward destructive root-knot nematodes, and continuous development in nanotechnology is supposed to enhance the utilization efficiency of nematicides to meet practical needs. Herein, a cationic star polymer (SPc) was constructed to load fluopyram (flu) and prepare a flu nanoagent. Hydrogen bonding and van der Waals forces facilitated the self-assembly of the flu nanoagent, leading to the breakdown of self-aggregated flu and reducing its particle size to 60 nm.

Multifunctional Nanoparticles and Nanopesticides in Agricultural Application.

The unscientific application of pesticides can easily cause a series of ecological environmental safety issues, which seriously restrict the sustainable development of modern agriculture. The great progress in nanotechnology has allowed the continuous development of plant protection strategies. The nanonization and delivery of pesticides offer many advantages, including their greater absorption and conduction by plants, improved efficacy, reduced dosage, delayed resistance, reduced residues, and protection from natural enemies and beneficial insects.

Hyperuricemia is associated with more cardiometabolic risk factors in hypertensive younger Chinese adults than in elderly.

Background: Numerous studies have shown that hyperuricemia (HUA) is associated with cardiovascular and renal outcomes, but few studies specifically explored the effect of age on this relationship. Therefore, our study aimed to explore the relationship between HUA and other cardiometabolic risk factors in different age groups.

Methods: This cross-section study used the data from Survey on uric acid in Chinese subjects with essential hypertension (SUCCESS).

The RNA export and RNA decay complexes THO and TRAMP prevent transcription-replication conflicts, DNA breaks, and CAG repeat contractions.

Expansion of structure-forming CAG/CTG repetitive sequences is the cause of several neurodegenerative disorders and deletion of repeats is a potential therapeutic strategy. Transcription-associated mechanisms are known to cause CAG repeat instability. In this study, we discovered that Thp2, an RNA export factor and member of the THO (suppressors of transcriptional defects of hpr1Δ by overexpression) complex, and Trf4, a key component of the TRAMP (Trf4/5-Air1/2-Mtr4 polyadenylation) complex involved in nuclear RNA polyadenylation and degradation, are necessary to prevent CAG fragility and repeat contractions in a Saccharomyces cerevisiae model system.
