SEPT5 overexpression predicts poor prognosis and promotes progression through feedback regulation of HIF-1α in clear cell renal cell carcinoma.

Clear cell renal cell carcinoma (ccRCC), a predominant subtype of renal cell carcinoma, significantly contributes to the heightened morbidity and mortality in individuals diagnosed with urologic tumors. The challenges posed by high malignancy at the initial diagnosis of ccRCC, therapeutic resistance, and unfavorable patient prognosis remain largely unresolved. Our findings indicate that SEPT5 is upregulated in ccRCC and this upregulation is associated with an adverse prognosis for ccRCC patients.

Mapping the chromothripsis landscape in urothelial carcinoma unravels great intratumoral and intertumoral heterogeneity.

Chromothripsis, a hallmark of cancer, is characterized by extensive and localized DNA rearrangements involving one or a few chromosomes. However, its genome-wide frequency and characteristics in urothelial carcinoma (UC) remain largely unknown. Here, by analyzing single-regional and multi-regional whole-genome sequencing (WGS), we present the chromothripsis blueprint in 488 UC patients.

Suppression of epileptic seizures by transcranial activation of K-selective channelrhodopsin.

Optogenetics is a valuable tool for studying the mechanisms of neurological diseases and is now being developed for therapeutic applications. In rodents and macaques, improved channelrhodopsins have been applied to achieve transcranial optogenetic stimulation. While transcranial photoexcitation of neurons has been achieved, noninvasive optogenetic inhibition for treating hyperexcitability-induced neurological disorders has remained elusive.

Advances in the impact of ASS1 dysregulation on metabolic reprogramming of tumor cells.

ASS1(argininosuccinate synthase 1) is a rate-limiting enzyme in the urea cycle, catalyzing the synthesis of argininosuccinate from citrulline and aspartate to ultimately produce arginine and support cellular metabolism. Increasing evidence suggests that ASS1 is commonly dysregulated in the tumor microenvironment, promoting tumor cell metastasis and infiltration. With a deeper understanding of tumor metabolic reprogramming in recent years, the impact of ASS1 dysregulation on abnormal tumor metabolism has attracted growing interest among researchers.

Suppressed P3-O3' Phase Transition and Enhanced Na Diffusion Kinetics of O3-Type Layered Oxide Cathode via Multivariate Doping.

O3-NaNiFeMnO has attracted much attention as a cathode for sodium-ion batteries, because of its low cost and high sodium-ion storage capacity. However, its slow Na diffusion kinetics and harmful P3-O3' phase transition with severe bulk strain at high voltage leads to poor rate capability and fast capacity fading. Herein, we propose a multivariate doping strategy with Cu, Mg, and Ti ions to solve the above problems of the O3-NaNiFeMnO cathode.

Chain-based lattice printing for efficient robotically-assembled structures.

Due to the nature of their implementation, nearly all low-level fabrication processes produce solidly filled structures. However, lattice structures are significantly stronger for the same amount of material, resulting in structures that are much lighter and more materially efficient. Here we propose an approach for fabricating lattice structures that echoes 3D printing techniques.
