Dual-Targeting Antiproliferation Hybrids Derived from 1-Deoxynojirimycin and Kaempferol Induce MCF-7 Cell Apoptosis through the Mitochondria-Mediated Pathway.

J Nat Prod 2021 May 12. Epub 2021 May 12.

School of Biotechnology, Jiangsu University of Science and Technology, Zhenjiang, Jiangsu 212100, People's Republic of China.

1-Deoxynojirimycin, an α-glucosidase inhibitor, possesses various biological activities such as antitumor, antidiabetic, and antiviral effects. However, the application of 1-deoxynojirimycin is restricted by its poor lipophilicity and low bioavailability. In this study, three 1-deoxynojirimycin derivatives (-) comprising 1-deoxynojirimycin and kaempferol were designed and synthesized to modify their pharmacokinetics and improve their antitumor efficacy.

Inhibition of γH2AX, COX-2 and regulation of antioxidant enzymes in MPP-exposed SH-SY5Y cells pre-treated with rutin.

Metab Brain Dis 2021 May 12. Epub 2021 May 12.

Department of Medical Biosciences, University of the Western Cape, Robert Sobukwe Road, Private Bag X17, Bellville, 7535, South Africa.

Many plant-derived bioactive compounds such as rutin are reportedly effective in attenuating neuronal death in most neurodegenerative disorders. Parkinson's disease (PD) is characterized by the gradual degeneration of dopaminergic neurons in the substantia nigra of the midbrain, and has previously been modelled in-vitro through the specific neurotoxic activity of 1-methyl-4-phenylpyridinium (MPP) on dopaminergic neurons. Rutin is a bioflavonoid with multiple pharmacological effects, and this study investigated the neuroprotective effects of rutin in the human dopaminergic SH-SY5Y cell line using the neurotoxin MPP.

IL-23R gene polymorphisms in rheumatoid arthritis.

Rheumatol Int 2021 May 12. Epub 2021 May 12.

Division of Rheumatology, Department of Internal Medicine, Pamukkale University Faculty of Medicine, Denizli, Turkey.

Rheumatoid arthritis (RA) is a common autoimmune disease in which many different genetic variants of functional gene polymorphisms may play a culprit role in the underlying pathogenetic mechanism. The recent studies suggest that interleukin-23 receptor (IL-23R) gene polymorphisms may increase susceptibility to the development of various autoimmune diseases. We aimed to examine the possible relationship of nine single nucleotide polymorphisms (SNPs) in the IL-23R gene to susceptibility to rheumatoid arthritis and their associations with disease characteristics in the South Aegean region of Turkey.

Redox-related gene expression and sugar accumulation patterns are altered in the edible inflorescence produced by the cultivated form of pacaya palm (Chamaedorea tepejilote).

Ann Bot 2021 May 12. Epub 2021 May 12.

Institut de Recherche pour le Développement (IRD), UMR DIADE, Université de Montpellier, Montpellier, France.

Background And Aims: The pacaya palm is a dioecious neotropical palm species that is exploited in Latin America for its male inflorescence which is edible when immature. It is cultivated, in a non-intensive manner, in Guatemala, where a morphotype occurs that produces much larger, more highly branched inflorescences compared to wild palms. We sought to identify molecular factors underlying this phenotypic divergence, which is likely to be a product of domestication. Read More

Vitamin E regulates bovine granulosa cell apoptosis via NRF2-mediated defense mechanism by activating PI3K/AKT and ERK1/2 signaling pathways.

Reprod Domest Anim 2021 May 12. Epub 2021 May 12.

College of Animal Science and Technology, Hebei Agricultural University, Baoding, Hebei, 071000, People's Republic of China.

High-yield dairy cows are usually subject to high-intensive cell metabolism and produce excessive reactive oxygen species (ROS). Once ROS is beyond the threshold of scavenging ability, it can induce oxidative stress, imperiling the reproductive performance of cows. The study was to investigate the effects of vitamin E (VE) on H O -induced proliferation and apoptosis of bovine granulosa cells and the underlying molecular mechanism. Read More

Dual Size/Charge-Switchable Nanocatalytic Medicine for Deep Tumor Therapy.

Adv Sci (Weinh) 2021 05 1;8(9):2002816. Epub 2021 Mar 1.

State Key Lab of High Performance Ceramics and Superfine Microstructures Shanghai Institute of Ceramics Chinese Academy of Sciences Shanghai 200050 P. R. China.

Elevating intratumoral levels of highly toxic reactive oxygen species (ROS) by nanocatalytic medicine for tumor-specific therapy without using conventional toxic chemodrugs is recently of considerable interest, which, however, still suffers from less satisfactory therapeutic efficacy due to the relatively poor accumulation at the tumor site and largely blocked intratumoral infiltration of nanomedicines. Herein, an ultrasound (US)-triggered dual size/charge-switchable nanocatalytic medicine, designated as Cu-LDH/HMME@Lips, is constructed for deep solid tumor therapy via catalytic ROS generations. The negatively charged liposome outer-layer of the nanomedicine enables much-prolonged blood circulation for significantly enhanced tumoral accumulation, while the positively charged Fenton-like catalyst Cu-LDH released from the liposome under the US stimulation demonstrates much enhanced intratumoral penetration via transcytosis.

Assessment of the effect of long-term exposure to microplastics and depuration period in Sparus aurata Linnaeus, 1758: Liver and blood biomarkers.

Sci Total Environ 2021 May 3;786:147479. Epub 2021 May 3.

Instituto Español de Oceanografía, Centro Oceanográfico de Baleares, Muelle de Poniente s/n, E-07015 Palma de Mallorca, Balearic Islands, Spain. Electronic address:

The constant increase in plastic pollution has attracted great attention in recent years due to its potential detrimental effects on organisms and ecosystems. While the consequences of ingestion of large plastic litter are mostly understood, the impacts resulting from a long-term exposure and a recovery period of microplastics (MPs) are still limited. The aims were to monitor oxidative stress, detoxification and inflammatory biomarkers in liver, plasma and erythrocytes of Sparus aurata exposed during 90 days to low-density polyethylene (LDPE)-MPs enriched diet (10% by weight) followed by 30 days of depuration.

Regulation of plasmodesmata in leaves of Arabidopsis: ATP, NADPH and chlorophyll b levels matter.

J Exp Bot 2021 May 11. Epub 2021 May 11.

Laboratory of Molecular and Ecological Physiology, Komarov Botanical Institute, Russian Academy of Sciences, ul. Professora Popova 2, 197376 St.-Petersburg, Russia.

In mature leaves, cell-to-cell transport via plasmodesmata (PD) between mesophyll cells links assimilate production in photosynthesis with their export to sink organs. This study addresses the question how signals derived from chloroplasts and photosynthesis influence PD permeability. Cell-to-cell transport was analyzed in leaves of Arabidopsis chlorophyll b-less ch1-3 mutant, the same mutant complemented with a cyanobacterial CAO gene (PhCAO) over-accumulating chlorophyll b, the trxm3 mutant lacking plastidial thioredoxin m3, and the ntrc mutant lacking functional NADPH : thioredoxin reductase C.

Effects of supplementing a healthy diet with pecan nuts or extra-virgin olive oil on inflammatory profile of patients with stable coronary artery disease: a randomized clinical trial.

Br J Nutr 2021 May 11:1-27. Epub 2021 May 11.

Graduate Program in Health Sciences (Cardiology), Instituto de Cardiologia/Fundação Universitária de Cardiologia do Rio Grande do Sul (IC/FUC). 395 Princesa Isabel Avenue, 90040-371, Porto Alegre, Rio Grande do Sul, Brazil.

The consumption of nuts and extra-virgin olive oil has been associated with suppression of inflammatory pathways that contribute to atherosclerosis, but its role on the modulation of the inflammatory profile in patients with established coronary artery disease (CAD) is unclear. The aim of this study was to evaluate the effects of adding pecan nuts or extra-virgin olive oil to a healthy diet on inflammatory markers in patients with stable CAD. In this randomized clinical trial, 204 patients were enrolled to three study groups: 67 to control group (CG: healthy diet), 68 to pecan nuts group (PNG: 30g/day of pecans + healthy diet) and 69 to extra-virgin olive oil group (OOG: 30ml/day of extra-virgin olive oil + healthy diet).
