Nanoscale Spatial Organization of ARC High‐ and Low‐Order Assemblies at Excitatory Synapses

Advanced Science, EarlyView.
ARC (Activity‐Regulated Cytoskeleton‐Associated protein) mediates synaptic plasticity by forming nanoscale assemblies in neurons. Using super‐resolution microscopy and time‐resolved anisotropy with targeted tagging, the study reveals low‐order ARC assemblies at synapses colocalizing with AMPARs, semi‐circular structures at endocytic zones, and 60–80 nm

In vitro cultivation of the embryos of hybrid forms of early-ripening sweet cherry (Prunus avium L.) varieties

Вавиловский журнал генетики и селекции, 2019
Russia does not possess  as many highly adaptable, technological, early-ripening varieties of sweet  cherry (Prunus avium L.) as would suffice to feel comfortable. Therefore, breeders are faced with the task of obtaining hybrid seeds as soon  as possible.

An Activity‐Dependent NEPAS–PTX3 Axis Links Neurovascular and Myelin Deficits to Cognitive Impairment

Advanced Science, EarlyView.
An activity‐dependent pathway links prefrontal circuit hypoactivity to cognitive impairment. Reduced PVA–mPFC activity upregulates NEPAS, which suppresses PTX3 secretion, leading to impaired angiogenesis, myelin deficits, and memory decline. Rescue is achieved by NEPAS knockdown or chemogenetic circuit activation.

EFFECT OF ETHYL METHANESULFONATE (EMS) AND N-NITROSE-N´-ETHYL UREA (ENU) ON CALLUS GROWTH OF COMMON BEAN [PDF]

Journal of Central European Agriculture, 2005
Infl uence of ethyl methanesulfonate (EMS) and N-nitrose-N´-ethyl urea (ENU) mutagenic treatments was investigated on three time sub-cultured calli obtained from leaf petiole explants of 7-day old sterile plants.

Cuproptosis and Mitophagy Mediated by the THUMPD1/IGF2R‐Dependent Suppression of AKT and Activation of AMPK Signaling Suppress Lung Adenocarcinoma Progression

Advanced Science, EarlyView.
THUMPD1 drives a tumor‐suppressive signaling cascade in lung adenocarcinoma by promoting IGF2R expression. IGF2R associates with PPP2R1A to suppress AKT and activate AMPK, leading to SLC31A1 upregulation and copper accumulation. Elevated copper disrupts mitochondrial metabolism and induces excessive mitophagy, thereby restraining tumor growth and ...
