Membrane-Localized Orientation of NONPHOTOTROPIC HYPOCOTYL3 Affects the Necessity of Its Phosphorylation for Phototropism.

NONPHOTOTROPIC HYPOCOTYL3 (NPH3) is a key regulator of hypocotyl phototropism under both low- and high-intensity blue light (LBL/HBL), mediating phototropin1 (phot1) and phot2 signaling. NPH3 undergoes dephosphorylation and is released from the plasma membrane (PM) upon blue light irradiation. However, how its phosphorylation status and PM localization mediate phot1 and phot2 signaling in Arabidopsis (Arabidopsis thaliana) remains elusive.

Can the aerosol pollution extreme events be revealed by global reanalysis products?

Extreme aerosol pollution poses significant risks to the climate, environment, and human health. To investigate the formation and impacts of aerosol pollution extreme events (APEE), the reanalysis product presents meticulous spatiotemporal information on the three-dimensional distribution of aerosols. However, there is a lack of comprehensive evaluation and information regarding the data quality of reanalysis products employed in APEE research, as well as limited understanding of their spatial and temporal distribution, variation, and long-term trends.

Phototropin 1 Mediates High-Intensity Blue Light-Induced Chloroplast Accumulation Response in a Root Phototropism 2-Dependent Manner in Mutant Plants.

Phototropins, namely, phototropin 1 (phot1) and phototropin 2 (phot2), mediate chloroplast movement to maximize photosynthetic efficiency and prevent photodamage in plants. Phot1 primarily functions in chloroplast accumulation process, whereas phot2 mediates both chloroplast avoidance and accumulation responses. The avoidance response of phot2-mediated chloroplasts under high-intensity blue light (HBL) limited the understanding of the function of phot1 in the chloroplast accumulation process at the HBL condition.

A high concentration of abscisic acid inhibits hypocotyl phototropism in Gossypium arboreum by reducing accumulation and asymmetric distribution of auxin.

Hypocotyl phototropism is mediated by the phototropins and plays a critical role in seedling morphogenesis by optimizing growth orientation. However, the mechanisms by which phototropism influences morphogenesis require additional study, especially for polyploid crops such as cotton. Here, we found that hypocotyl phototropism was weaker in Gossypium arboreum than in G.

Macrophage Heterogeneity in Kidney Injury and Fibrosis.

Kidney macrophages are central in kidney disease pathogenesis and have therapeutic potential in preventing tissue injury and fibrosis. Recent studies highlighted that kidney macrophages are notably heterogeneous immune cells that fulfill opposing functions such as clearing deposited pathogens, maintaining immune tolerance, initiating and regulating inflammatory responses, promoting kidney fibrosis, and degrading the extracellular matrix. Macrophage origins can partially explain macrophage heterogeneity in the kidneys.

Glyceraldehyde-3-Phosphate Dehydrogenase of Is a Plasminogen- and Actin-Binding Protein.

, an intraerythrocytic protozoa, can cause an emerging tick-borne disease-Human babesiosis. The parasite can successfully invade host red blood cells owing to the assistance of molecules expressed by babesia. Glyceraldehyde-3-phosphate dehydrogenase (GAPDH), the housekeeping intracellular glycolytic enzyme, can also be expressed in the external of cells, where contributes to binding to several molecules such as plasminogen and actin.

Human Babesiosis in China: a systematic review.

Human babesiosis, a worldwide emerging tick-borne disease, is caused by the intraerythrocytic apicomplexan parasite, babesia. In recent years, the number of infected patients globally has continued to rise, and thus human babesiosis poses a significant public health threat. Therefore, stronger initiatives should be undertaken to prevent further spread and development of this disease.

Oral administration of indole substituted dipyrido[2,3-d]pyrimidine derivative exhibits anti-tumor activity via inhibiting AKT and ERK1/2 on hepatocellular carcinoma.

Development of an effective and safe anti-cancer drug is an urgent request for hepatocellular carcinoma (HCC). In this study, we synthesized a series of novel indole substituted dihydropyrido[2,3-d]pyrimidines through the multicomponent reactions to connect pyrido[2,3-d]pyrimidine and indole moities via an one-pot three-component reaction of 3-cyanoacetyl indoles 1, various aromatic aldehyde 2, and 2,6-diaminopyrimidin-4(3H)-one 3. Subsequently, we screened their cytotoxicity via CCK-8 assay in HepG2 cells, a human hepatoma cell line and chose compound 4p that showed the lowest dosage of IC50 to study the antitumor activities to HCC.

Novel applications for an established antimalarial drug: tumoricidal activity of quinacrine.

Quinacrine (QC), a synthetic antimalarial drug, was consistently used worldwide to combat malaria during the last century. Interestingly, later studies revealed that it also displays various additional properties, specifically antitumor activity. QC's antitumor activity occurs via a variety of pathways, including DNA intercalation, angiogenesis inhibition, signal transduction regulation, cell cycle arrest and autophagy induction.

Microphysical effects determine macrophysical response for aerosol impacts on deep convective clouds.

Deep convective clouds (DCCs) play a crucial role in the general circulation, energy, and hydrological cycle of our climate system. Aerosol particles can influence DCCs by altering cloud properties, precipitation regimes, and radiation balance. Previous studies reported both invigoration and suppression of DCCs by aerosols, but few were concerned with the whole life cycle of DCC.
