The SRC-TOPK positive feedback loop promotes RB1 phosphorylation and drives the development of lung squamous cell carcinoma.

Lung squamous cell carcinoma (LUSC) is a common subtype of non-small cell lung cancer, with limited treatment options and poor patient prognosis. Currently, common driver mutations in lung adenocarcinoma rarely occur in LUSC; the mutated genes found in LUSCs lack corresponding targeted drugs. Therefore, it is necessary to discover new therapeutic targets for LUSC and provide patients with more treatment options.

The GGH/HuR Complex Binds and Stabilizes mRNAs to Maintain Tumor Cell Cycle and DNA Replication.

GGH (Gamma-glutamyl hydrolase) is a folate metabolism enzyme that hydrolyzes intracellular polyglutamylated folates and is highly expressed in various cancers. It remains unclear whether GGH functions as an oncogene and its underlying mechanisms in tumor progression. Here, it is reported that GGH silencing inhibited the growth of lung cancer cells in vivo and in vitro.

HO Production via Artificial Photosynthesis Over Defective Graphitic Carbon Nitride.

Metal-free graphitic carbon nitride has been considered as a promising candidate for hydrogen peroxide (HO) photosynthesis, with the advantage of low-cost, high stability, and environmentally friendly capacity. However, such a solar-to-chemical conversion still suffers from limited light utilization, confined surface adsorption, and restricted reduction/oxidation reaction pathway. At this juncture, this bottleneck has been overcome through diverse modifications over carbon nitride, such as defect engineering graphitic carbon nitride with modulated physical and chemical properties, which performs satisfactory visible-light absorption, sufficient active sites, and promotes charge transfer kinetics for artificial solar-to-chemical conversion.

A new selective mediastinal lymph node dissection for clinical peripheral stage IA invasive non-small-cell lung cancer: a propensity-score matching study.

A General Strategy for Controllable Preparation of Nano-CaCO.

Controllable preparation of inorganic nanomaterials with specific morphology and structure is very important for their applications in various fields. Herein, a general strategy was proposed to controllably synthesize nano-CaCO via a water-in-oil microemulsion method in the rotating packed bed reactor. By tuning key parameters, nano-CaCO with four primarily analyzed morphologies, including spherical, spindle-like, clustered, or linear formations, can be selectively obtained.

PFKP silencing suppresses tumor growth via the AXL-MET axis.

PFKP Phosphofructokinase, Platelet Type isoform), as an essential metabolic enzyme, contributes to the high glycolysis rates seen in cancers while its role in oncogenic pathways, especially from a non-metabolic aspect, is not fully understood. We found that PFKP was highly expressed in NSCLC and was related to poor patient survival. Knockdown of PFKP significantly inhibited cell proliferation, colony formation, invasion, and migration of NSCLC cells.

Total Synthesis of Tipranavir Based on Iridium-Catalyzed Asymmetric Allylic Substitution of Dihydropyranone.

An efficient and highly enantioselective synthesis of tipranavir is realized based on an iridium-catalyzed asymmetric allylic substitution. High yield and diastereoselectivity (>20:1), as well as excellent enantioselectivity (99% ), were obtained for the key intermediate through direct asymmetric alkylation reaction of dihydropyranone with allylic -butyl carbonate. Anti-AIDS drug of tipranavir was finally accomplished in 8 steps and 6 pots starting from commercially available 1-phenyl-3-hexanone in 20.

ΔNp63α promotes radioresistance in esophageal squamous cell carcinoma through the PLEC-KEAP1-NRF2 feedback loop.

Esophageal squamous cell carcinoma (ESCC) is one of the most aggressive cancers and is highly prevalent in China, exhibiting resistance to current treatments. ΔNP63α, the main isoform of p63, is frequently amplified in ESCC and contributes to therapeutic resistance, although the molecular mechanisms remain unknown. Here, we report that ΔNP63α is highly expressed in ESCC and is associated with radioresistance by reducing ROS level.

Asymmetric Microenvironment Tailoring Strategies of Atomically Dispersed Dual-Site Catalysts for Oxygen Reduction and CO Reduction Reactions.

Dual-atom catalysts (DACs) with atomically dispersed dual-sites, as an extension of single-atom catalysts (SACs), have recently become a new hot topic in heterogeneous catalysis due to their maximized atom efficiency and dual-site diverse synergy, because the synergistic diversity of dual-sites achieved by asymmetric microenvironment tailoring can efficiently boost the catalytic activity by optimizing the electronic structure of DACs. Here, this work first summarizes the frequently-used experimental synthesis and characterization methods of DACs. Then, four synergistic catalytic mechanisms (cascade mechanism, assistance mechanism, co-adsorption mechanism and bifunction mechanism) and four key modulating methods (active site asymmetric strategy, transverse/axial-modification engineering, distance engineering and strain engineering) are elaborated comprehensively.

JCVI: A versatile toolkit for comparative genomics analysis.

The life cycle of genome builds spans interlocking pillars of assembly, annotation, and comparative genomics to drive biological insights. While tools exist to address each pillar separately, there is a growing need for tools to integrate different pillars of a genome project holistically. For example, comparative approaches can provide quality control of assembly or annotation; genome assembly, in turn, can help to identify artifacts that may complicate the interpretation of genome comparisons.

Predictive role and molecular biological function of proline-rich small repeat protein SPRR3 in the diagnosis of lung adenocarcinoma.

The fascinating role of SPRR3 in various malignant tumors has prompted extensive research to unravel its expression patterns and prognostic significance. To comprehensively investigate SPRR3, we leveraged multiple datasets containing invaluable biomedical information, specifically focusing on the comparative analysis of SPRR3 gene expression levels across different cancer types. Meticulous examination of lung adenocarcinoma allowed us to delve deeper into the correlation between SPRR3 expression and its molecular biological functions.

Chromosome-level scaffolding of haplotype-resolved assemblies using Hi-C data without reference genomes.

Scaffolding is crucial for constructing most chromosome-level genomes. The high-throughput chromatin conformation capture (Hi-C) technology has become the primary scaffolding strategy due to its convenience and cost-effectiveness. As sequencing technologies and assembly algorithms advance, constructing haplotype-resolved genomes is increasingly preferred because haplotypes can provide additional genetic information on allelic and non-allelic variations.

Remarkable Toughening of Plastic with Monodispersed Nano-CaCO: From Theoretical Predictions to Experimental Validation.

The structure-property relationship of poly(vinyl chloride) (PVC)/CaCO nanocomposites is investigated by all-atom molecular dynamics (MD) simulations. MD simulation results indicate that the dispersity of nanofillers, interfacial bonding, and chain mobility are imperative factors to improve the mechanical performance of nanocomposites, especially toughness. The tensile behavior and dissipated work of the PVC/CaCO model demonstrate that 12 wt % CaCO modified with oleate anion and dodecylbenzenesulfonate can impart high toughness to PVC due to its good dispersion, favorable interface interaction, and weak migration of PVC chains.

GLUT1 promotes cell proliferation via binds and stabilizes phosphorylated EGFR in lung adenocarcinoma.
