Three PP2C phosphatases modulate FERONIA receptor kinase activity to regulate pollen-stigma interaction in Arabidopsis.

Pollen hydration represents the initial and critical step in pollen-stigma interactions and is necessary for successful plant fertilization. The FERONIA (FER) receptor kinase regulates pollen hydration by modulating stigmatic reactive oxygen species (ROS) accumulation through rapid alkalinization factor 23/33 (RALF23/33) and pollen coat protein B-class peptide (PCP-B) signaling. However, the function and regulatory mechanism of FER's receptor kinase activity in pollen hydration remain poorly understood.

Constructing crystalline NiCoO/amorphous MoNiCo-LDH through high valence Mo doping for high-performance hybrid supercapacitors.

In this work, a crystalline/amorphous electrode material was prepared a simple method. Specifically, high-valent Mo was introduced to fabricate amorphous MNC-LDH, which was then used to construct crystalline NCO/amorphous MNC-LDH composite materials. The prepared sample exhibited a three-dimensional pompom-like structure composed of ultrathin nanoflakes and a hybrid interface between crystalline and amorphous phases, which benefited its electrochemical performance.

A map of enhancer regions in primary human neural progenitor cells using capture STARR-seq.

Genome-wide association studies (GWASs) and expression analyses implicate noncoding regulatory regions as harboring risk factors for psychiatric disease, but functional characterization of these regions remains limited. Here, we perform capture STARR-sequencing of over 70,000 candidate regions to identify active enhancers in primary human neural progenitor cells (phNPCs). We select candidate regions by integrating data from NPCs, prefrontal cortex, developmental timepoints, and GWASs.

PCP-B peptides and CrRLK1L receptor kinases control pollination via pH gating of aquaporins in Arabidopsis.

During pollen-stigma interaction, pollen coat protein B-class peptides (PCP-Bs) compete with stigmatic rapid alkalinization factor (RALF) for interaction with FERONIA/ANJEA receptor kinases (FER/ANJ), stimulating pollen hydration and germination. However, the molecular mechanism underlying PCP-Bs-induced, FER/ANJ-regulated compatible responses remains largely unknown. Through PCP-Bγ-induced phosphoproteomic analysis, we characterized a series of pollination-related signaling pathways regulated by FER/ANJ.

Removal of cefuroxime from aqueous solution by biochars derived from antibiotic mycelial residue.

In China, antibiotic mycelial residue is categorized as hazardous waste. To achieve the harmless and resourceful disposal of cephalosporin, three types of biochars from cephalosporin mycelia residues, namely non-activated carbon (BC1), ZnCl-activated carbon (BC2), and KOH-activated carbon (BC3), were respectively fabricated by high-temperature pyrolysis carbonization technology. These three kinds of biochars were characterized via iodine value, FTIR, and SEM, and the adsorption performance of the prepared biochars was investigated using cefuroxime (CXM) as the adsorption target.

Synthetic lethal connectivity and graph transformer improve synthetic lethality prediction.

Synthetic lethality (SL) has shown great promise for the discovery of novel targets in cancer. CRISPR double-knockout (CDKO) technologies can only screen several hundred genes and their combinations, but not genome-wide. Therefore, good SL prediction models are highly needed for genes and gene pairs selection in CDKO experiments.

Perovskite Probe-Based Machine Learning Imaging Model for Rapid Pathologic Diagnosis of Cancers.

Accurately distinguishing tumor cells from normal cells is a key issue in tumor diagnosis, evaluation, and treatment. Fluorescence-based immunohistochemistry as the standard method faces the inherent challenges of the heterogeneity of tumor cells and the lack of big data analysis of probing images. Here, we have demonstrated a machine learning-driven imaging method for rapid pathological diagnosis of five types of cancers (breast, colon, liver, lung, and stomach) using a perovskite nanocrystal probe.

The MaxEnt model was used to construct the potential distribution areas of in different periods such as the last interglacial (LIG), the last glacial maximum (LGM), the mid-Holocene (MID), and the current and future (2050s and 2070s).

Two new compounds isolated from the aerial parts of blume.

Two new aromatic compounds, namely gastupdin A (), and gastupdin B (), together with three known compounds, arundin(), phomosines B () and monocillin IV (), were isolated from the aerial parts of Blume. The structures of the new compounds were confirmed through spectral analyses including NMR, HR-ESI-MS, ECD, UV, and IR. All isolated compounds were evaluated for their neuroprotective effects against 6-hydroxydopamine-induced cell death in Human Neuroblastoma Cells, with curcumin as the positive control, however, the activity of all compounds was weaker than the positive control, showing no significant activity.

The biosynthesis of storage reserves and auxin is coordinated by a hierarchical regulatory network in maize endosperm.

Grain filling in maize (Zea mays) is intricately linked to cell development, involving the regulation of genes responsible for the biosynthesis of storage reserves (starch, proteins, and lipids) and phytohormones. However, the regulatory network coordinating these biological functions remains unclear. In this study, we identified 1744 high-confidence target genes co-regulated by the transcription factors (TFs) ZmNAC128 and ZmNAC130 (ZmNAC128/130) through chromatin immunoprecipitation sequencing coupled with RNA-seq analysis in the zmnac128/130 loss-of-function mutants.

Osteosarcoma Multi-Omics Landscape and Subtypes.

Osteosarcoma (OS) is the most common primary bone malignancy that exhibits remarkable histologic diversity and genetic heterogeneity. The complex nature of osteosarcoma has confounded precise molecular categorization, prognosis, and prediction for this disease. In this study, we performed a comprehensive multiplatform analysis on 86 osteosarcoma tumors, including somatic copy-number alteration, gene expression and methylation, and identified three molecularly distinct and clinically relevant subtypes of osteosarcoma.

SLKB: synthetic lethality knowledge base.

Emerging CRISPR-Cas9 technology permits synthetic lethality (SL) screening of large number of gene pairs from gene combination double knockout (CDKO) experiments. However, the poor integration and annotation of CDKO SL data in current SL databases limit their utility, and diverse methods of calculating SL scores prohibit their comparison. To overcome these shortcomings, we have developed SL knowledge base (SLKB) that incorporates data of 11 CDKO experiments in 22 cell lines, 16,059 SL gene pairs and 264,424 non-SL gene pairs.
