Background: Sp1, a transcription factor, regulates essential cellular processes and plays important tumorigenic roles across diverse cancers. However, comprehensive pan-cancer analyses of its expression and potential immunomodulatory roles remain unexplored.

Methods: Utilizing bioinformatics tools and public datasets, we examined the expression of Sp1 across normal tissues, tumors, and immune cells, and screened for pre- and post-transcriptional modifications, including genetic alterations, DNA methylation, and protein phosphorylation, affecting its expression or function.

Alectinib Versus Crizotinib in Asian Patients With Treatment-Naïve Advanced -Positive NSCLC: Five-Year Update From the Phase 3 ALESIA Study.

Introduction: Previous results from the phase 3 ALESIA study (NCT02838420) revealed that alectinib (a central nervous system [CNS]-active, ALK inhibitor) had clinical benefits in treatment-naïve Asian patients with advanced -positive NSCLC, consistent with the global ALEX study. We present updated data after more than or equal to 5 years of follow-up from the "last patient in" date.

Methods: Adult patients with treatment-naïve, advanced -positive NSCLC from mainland China, South Korea, and Thailand were randomized 2:1 to receive twice-daily 600 mg alectinib (n = 125) or 250 mg crizotinib (n = 62).

Tunable polarization control with self-assembled arrays of anisotropic plasmonic coaxial nanocavities.

Polarization control with nanostructures having a tunable design and allowing inexpensive large-scale fabrication is important for many nanophotonic applications. For this purpose, we developed and experimentally demonstrated nanostructured plasmonic surfaces based on hexagonal arrays of anisotropic coaxial nanocavities, which can be fabricated by a low-cost self-assembled nanosphere lithography method. Their high polarization sensitivity is achieved by engineering anisotropy of the coaxial nanocavities, while the optical response is enhanced by the excitation of surface plasmon resonances.

High-Performance Solar-Blind Photodetector Based on (010)-Plane β-GaO Thermally Oxidized from Nonpolar (110)-Plane GaN.

A high-performance planar structure metal-semiconductor-metal-type solar-blind photodetector (SBPD) was fabricated on the basis of (010)-plane β-GaO thermally oxidized from nonpolar (110)-plane GaN. A full width at half maximum of 0.486° was achieved for the X-ray rocking curve associated with (020)-plane β-GaO, which is better than most reported results for the heteroepitaxially grown (-201)-plane β-GaO.

Spatiotemporal evolution of ultrafast photocarrier dynamics across WS2-ReS2 lateral interface.

2D lateral heterostructures possess atomically sharp lateral interfaces, while understanding of their ultrafast photocarrier dynamics from a spatiotemporal viewpoint is rather elusive. In this study, we have investigated the spatiotemporal evolution of photocarrier dynamics across the 1D lateral interface of a WS2-ReS2 2D lateral heterostructure utilizing femtosecond laser pump-probe. The nontrivial band offset across the 1D lateral interface markedly mediates the spatiotemporal photocarrier transfer and transport processes.

PD-L1 mRNA derived from tumor-educated platelets as a potential immunotherapy biomarker in non-small cell lung cancer.

Background: To date, the role of programmed death ligand-1 (PD-L1) messenger RNA (mRNA) derived from tumor-educated platelets (TEPs) has not been well investigated in patients with advanced non-small cell lung cancer (NSCLC).

Effective switching of an all-solid-state mode-locked laser by a graphene modulator.

Although sophisticated novel saturable absorber materials are available for the development of ultrafast lasers, innovative approaches and devices play an increasingly important role in continuously adjusting mode-locked lasers with electrical gating. In this study, electrically switched operational regimes of an Nd:YVO all-solid-state mode-locked laser with a high modulation ratio (from 900 ns to 15 ps) are demonstrated for the first time. The laser can automatically switch multiple operation regimes with the assistance of electrical signals using techniques such as Q-switching, Q-switched mode-locking (QML), and continuous-wave mode-locking (CWML).
