Driver lines for studying associative learning in .

The mushroom body (MB) is the center for associative learning in insects. In , intersectional split-GAL4 drivers and electron microscopy (EM) connectomes have laid the foundation for precise interrogation of the MB neural circuits. However, investigation of many cell types upstream and downstream of the MB has been hindered due to lack of specific driver lines.

Nanoscale Hydrophobicity of Transport Barriers in the Nuclear Pore Complex as Compared with the Liquid/Liquid Interface by Scanning Electrochemical Microscopy.

The nuclear pore complex (NPC) is the proteinous nanopore that solely regulates molecular transport between the nucleus and cytoplasm of a eukaryotic cell. Hypothetically, the NPC utilizes the hydrophobic barriers based on the repeats of phenylalanine-glycine (FG) units to selectively and efficiently transport macromolecules. Herein, we quantitatively assess the hydrophobicity of transport barriers confined in the nanopore by applying scanning electrochemical microscopy (SECM).

Corticosterone-induced postpartum depression induces depression-like behavior and impairs hippocampal neurogenesis in adolescent offspring via HPA axis and BDNF-mTOR pathway.

Postpartum depression (PPD) adversely affects the growth and development of the offspring, increasing the risk of various internalizing behaviorsduring adolescence. Studies have shown that corticosterone (CORT)-induced PPD affects neurogenesis in the offspring, which is closely related to the onset of depression. However, the underlying mechanisms of these changes in the offspring of PPD mothers remain unexplored.

New insights into the regulation of cyp3a65 expression in transgenic tg(cyp3a65:GFP) zebrafish embryos.

Facing the need for alternative models allowing assessment of metabolic-endocrine disrupting chemicals (MDCs), especially in poorly investigated tissues such as the intestine, we recently developed a transgenic zebrafish embryo in vivo model, tg(cyp3a65:GFP), expressing the Green Fluorescent Protein (GFP) under the control of the zebrafish cyp3a65 promoter, ortholog of human cyp3a4, a gene coding for a key enzyme of intestinal xenobiotic and endobiotic metabolism. In this study, we aimed to better understand the regulation of cyp3a65 expression by zfPXR, zfAhR2, and zfGR zebrafish orthologs of well-known human xenosensors PXR and AhR, and steroid nuclear receptor GR. For this purpose, we performed zebrafish embryo tg(cyp3a65:GFP) (co)exposures to a variety of agonists (clotrimazole, TCDD, fluticasone propionate) and antagonists (econazole nitrate, CH223181, RU486), which were characterized using in vitro zebrafish reporter gene assays.

Vitamin B2 Operates by Dual Thermodynamic and Kinetic Mechanisms to Selectively Tailor Urate Crystallization.

Here we demonstrate how a biologically relevant molecule, riboflavin (vitamin B2), operates by a dual mode of action to effectively control crystallization of ammonium urate (NHHU), which is associated with cetacean kidney stones. In situ microfluidics and atomic force microscopy experiments confirm a strong interaction between riboflavin and NHHU crystal surfaces that substantially inhibits layer nucleation and spreading by kinetic mechanisms of step pinning and kink blocking. Riboflavin does not alter the distribution of tautomeric urate isomers, but its adsorption on NHHU crystal surfaces does interfere with the effects of minor urate tautomer by limiting its ability to induce NHHU crystal defects while also suppressing NHHU nucleation and inhibiting crystal growth by 80% at an uncharacteristically low modifier concentration.

Materials And Methods: We queried the prospective, multi-institutional Delayed Intervention and Surveillance for Small Renal Masses (DISSRM) registry for patients on AS with an imaging interval of ≥6 months, identifying 456 patients. We tracked tumour size over time; a GR >0.

Downregulation of AATK enhances susceptibility to ferroptosis by promoting endosome recycling in gefitinib-resistant lung cancer cells.

Ferroptosis has been characterised by disruption of the cell membrane through iron-related lipid peroxidation. However, regulation of iron homeostasis in lung cancer cells that are resistant to epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) remains unclear. Transcriptome analysis identified a significant downregulation of apoptosis-associated tyrosine kinase (AATK) mRNA expression in gefitinib-resistant PC9 (PC9-GR) cells, which were found to be more susceptible to ferroptosis inducers.

Self-Supported α-MoB/β-MoB Ceramic Electrodes for Efficient High-Current-Density Hydrogen Evolution in Acidic, Neutral, and Alkaline pH-Values.

This paper describes the production and high-current-density hydrogen evolution reaction (HER) performance in the whole pH range (from acidic to basic pH values) of self-supported α-MoB/β-MoB ceramic electrodes, aiming for use in industrial electrocatalytic water splitting. Tape-casting and phase-inversion process, followed by sintering, were employed to synthesize self-supported β-MoB ceramic electrodes, which exhibited well arranged large finger-like pores, providing numerous active sites and channels for electrolyte entry and hydrogen release. The reaction between β-MoB and the sintering aid of MoO produces α-MoB/β-MoB heterojunctions, which significantly improve the electrocatalytic performance.

The Arabidopsis Basic-Helix-Loop-Helix Transcription Factor LRL1 Activates Cell Wall-Related Genes during Root Hair Development.

Lotus japonicus-ROOT HAIR LESS1-LIKE1 (LRL1) of Arabidopsis thaliana encodes a basic helix-loop-helix (bHLH) transcription factor (TF) involved in root hair development. Root hair development is regulated by an elaborate transcriptional network, in which GLABRA2 (GL2), a key negative regulator, directly represses bHLH TF genes, including LRL1 and ROOT HAIR DEFECTIVE6 (RHD6). Although RHD6 and its paralogous TFs have been shown to connect downstream to genes involved in cell morphological events such as endomembrane and cell wall modification, the network downstream of LRL1 remains elusive.
