A truncated form of the ATP release channel pannexin 1 (Panx1), Panx1, is enriched in metastatic breast cancer cells and has been proposed to mediate metastatic cell survival by increasing ATP release through mechanosensitive Panx1 channels. However, whether Panx1 on its own [without the presence of wild-type Panx1 (wtPanx1)] mediates ATP release has not been tested. Here, we show that Panx1 by itself can form a constitutively active membrane channel, capable of releasing ATP even in the absence of wtPanx1.

Compared to common hydrogels, the inherent porosity within and among these hydrogel particles offers interconnected channels for substance exchange in addition to sufficient growth space for cells, thereby forming a three-dimensional culture system that highly mimics the in vivo microenvironment. Such characteristics enable MAP hydrogels to adapt to various requirements of biomedical applications, along with their excellent injectability and mechanical properties.

Background: Cranioplasty (CP), a surgical procedure that restores cranial integrity and potentially enhances neurological outcomes, is commonly performed following decompressive craniectomy for various reasons. However, there is considerable controversy and variation regarding the optimal timing for cranioplasty, particularly concerning its impact on neurological functional outcomes. This paper outlines the protocol for a multicenter, non-randomized controlled trial designed to investigate whether the timing of cranioplasty influences neurological outcomes.

Cysteine S-sulfinylation is an important oxidative post-translational modification on proteins that regulates a variety of cell and protein functions. Aberrant S-sulfinylation contributes to a range of human pathologies, such as cancer and cardiovascular disease. However, efforts to elucidate the roles of S-sulfinylation in physiology and disease have been hampered due to the lack of methodology for the selective and direct monitoring of this modification in living cells.

Dynamic assessment of cerebral blood flow (CBF) is crucial for the prevention and treatment of cerebrovascular diseases. Near-field coupling (NFC), due to its non-invasive and continuous advantages, holds significant promise in the dynamic assessment of CBF compared to traditional detection methods. However, challenges related to individual differences persist.

Nonetheless, the lack of reliable biomarkers remains a substantial hurdle in clinical practice. In this study, we identified dysregulated microRNAs (miRNAs) in NSCLC, revealing a significant downregulation of miR-3202 and an upregulation of miR-3182.

Electrocatalytic nitrogen reduction reaction (eNRR) offers a sustainable pathway for ammonia (NH3) production. Defect engineering has emerged as a promising strategy to enhance eNRR activity; however, it can concurrently amplify the competing hydrogen evolution reaction (HER), posing challenges for achieving high selectivity. Herein, VOx with systematically tuned defect sizes was engineered to establish a structure-activity relationship between defect size and eNRR performance.

Crystal structure prediction (CSP) is an evolving field aimed at discerning crystal structures with minimal prior information. Despite the success of various CSP algorithms, their practical applicability remains circumscribed, particularly for large and complex systems. Here, to address this challenge, we show an evolutionary structure generator within the MAGUS (Machine Learning and Graph Theory Assisted Universal Structure Searcher) framework, inspired by the symmetry principle.
