Article Abstract
Cell lines are extensively used tools, therefore a comprehensive proteomic overview of hepatocellular carcinoma (HCC) cell lines and an extensive spectral library for data independent acquisition (DIA) quantification are necessary. Here, we present the proteome of nine commonly used HCC cell lines covering 9,208 protein groups, and the HCC spectral library containing 253,921 precursors, 168,811 peptides and 10,098 protein groups. The proteomic overview reveals the heterogeneity between different cell lines, and the similarity in proliferation and metastasis characteristics and drug targets-expression with tumour tissues. The HCC spectral library generating consumed 108 hours' runtime for data dependent acquisition (DDA) of 48 runs, 24 hours' runtime for database searching by MaxQuant version 2.0.3.0, and 1 hour' runtime for processing by Spectronaut version 15.2. The HCC spectral library supports quantification of 7,637 protein groups of triples 2-hour DIA analysis of HepG2 and discovering biological alteration. This study provides valuable resources for HCC cell lines and efficient DIA quantification on LC-Orbitrap platform, further help to explore the molecular mechanism and candidate therapeutic targets.

Pathogenic variants in the gene COQ4 cause primary coenzyme Q deficiency, which is associated with symptoms ranging from early epileptic encephalopathy up to adult-onset ataxia-spasticity spectrum disease. We genetically modified commercially available wild-type iPS cells by using a CRISPR/Cas9 approach to create heterozygous and homozygous isogenic cell lines carrying the disease-causing COQ4 variants c.458C > T, p.

Purpose: Tumor comprehensive genomic profiling (CGP) may detect potential germline pathogenic/likely pathogenic (P/LP) alterations as secondary findings. We analyzed the frequency of potentially germline variants and large rearrangements (LRs) in the RATIONAL study, an Italian multicenter, observational clinical trial that collects next-generation sequencing-based tumor profiling data, and evaluated how these findings were managed by the enrolling centers.
Patients And Methods: Patients prospectively enrolled in the pathway-B of the RATIONAL study and undergoing CGP with the FoundationOne CDx assays were included in the analysis.

The hallmarks of mechanosensitive ion channels have been observed for half a century in various cell lines, although their mechanisms and molecular identities remained unknown until recently. Identification of the bona fide mammalian mechanosensory Piezo channels resulted in an explosion of research exploring the translation of mechanical cues into biochemical signals and dynamic cell morphology responses. One of the Piezo isoforms - Piezo1 - is integral in the erythrocyte (red blood cell; RBC) membrane.

Crosstalk between leukemic cells and their surrounding mesenchymal stromal cells (MSCs) in the bone marrow microenvironment is crucial for the pathogenesis of myelodysplastic syndromes (MDS) and is mediated by extracellular vesicles (EVs). The EV-specific miRNAs derived from MDS-MSCs remain poorly explored. EVs isolated from HS-5, an immortalized stromal cell line, promoted the proliferation and 5-azacytidine (AZA) resistance of SKM-1 cells.

Grain size substantially influences rice quality and yield. In this study, we identified (), a quantitative trait locus encoding an F-box protein that enhances grain length by promoting cell proliferation. The transcription factor OsbZIP35 represses expression, while COR1 interacts with OsTCP19, leading to its degradation.
