Bibliometric and visualized analysis on global trends and hotspots of TAK1 in regulated cell death: 1999 to 2024.

Background: Regulated cell death (RCD) is a genetically controlled form of cell death that plays an important role in organogenesis, tissue remodeling, and pathogenesis of cancers. Transforming growth factor-beta-activation kinase 1 (TAK1) is a member of the serine/threonine protein kinase family, which can respond to internal and external stimuli and participate in inflammatory responses through multiple signaling pathways and cellular processes. In the last two decades, the regulatory roles of TAK1 at the crossroads of multiple RCD pathways, including apoptosis, necroptosis, pyroptosis, and PANoptosis were revealed by 801 articles retrieved from the Web of Science Core Collection database.

Broad cross neutralizing antibodies against sarbecoviruses generated by SARS-CoV-2 infection and vaccination in humans.

The outbreaks of severe acute respiratory syndrome coronavirus (SARS-CoV-1), Middle East respiratory syndrome coronavirus (MERS-CoV), and SARS-CoV-2 highlight the need for countermeasures to prevent future coronavirus pandemics. Given the unpredictable nature of spillover events, preparing antibodies with broad coronavirus-neutralizing activity is an ideal proactive strategy. Here, we investigated whether SARS-CoV-2 infection and vaccination could provide cross-neutralizing antibodies (nAbs) against zoonotic sarbecoviruses.

The AP2 transcription factor BARE RECEPTACLE regulates floral organogenesis via auxin pathways in woodland strawberry.

During flower development, different floral organs are formed to ensure fertilization and fruit set. Although the genetic networks underlying flower development are increasingly well understood, less is known about the mechanistic basis in different species. Here, we identified a mutant of woodland strawberry (Fragaria vesca), bare receptacle (bre), which produces flowers with greatly reduced carpels and other floral organs.

Selective and sensitive detection of dimethyl phthalate in water using ferromagnetic nanomaterial-based molecularly imprinted polymers and SERS.

To overcome the complicated pretreatment, low selectivity and low sensitivity detection associated with the detection of dimethyl phthalate (DMP), this study synthesized ferromagnetic nanomaterials that coupled with surface enhanced Raman scattering (SERS) and molecular imprinting polymers (MIPs). The pretreatment process can be simplified by ferromagnetic nanomaterials, then FeO@SiO@Ag@MIPs selectively adsorbing DMP can be achieved, and SERS can be applied for DMP detection with high sensitivity. As a control, the non-imprinted polymers (NIPs) FeO@SiO@Ag@NIPs were synthesized.

CRISPR screen of venetoclax response-associated genes identifies transcription factor ZNF740 as a key functional regulator.

BCL-2 inhibitors such as venetoclax offer therapeutic promise in acute myeloid leukemia (AML) and other cancers, but drug resistance poses a significant challenge. It is crucial to understand the mechanisms that regulate venetoclax response. While correlative studies have identified numerous genes linked to venetoclax sensitivity, their direct impact on the drug response remains unclear.

The chloroplast-localized casein kinase II α subunit, CPCK2, negatively regulates plant innate immunity through promoting S-nitrosylation of SABP3.

The casein kinase II (CK2) complex consists of catalytic (α) and regulatory (β) subunits and is highly conserved throughout eukaryotes. Plant CK2 plays critical roles in multiple physiological processes; however, its function in plant immunity remains obscure. In this study, we demonstrated that the unique chloroplast-localized CK2 α subunit (CPCK2) is a negative regulator of Arabidopsis thaliana innate immunity.

Epigenetic regulation of noncanonical menin targets modulates menin inhibitor response in acute myeloid leukemia.

Menin inhibitors that disrupt the menin-MLL interaction hold promise for treating specific acute myeloid leukemia (AML) subtypes, including those with KMT2A rearrangements (KMT2A-r), yet resistance remains a challenge. Here, through systematic chromatin-focused CRISPR screens, along with genetic, epigenetic, and pharmacologic studies in a variety of human and mouse KMT2A-r AML models, we uncovered a potential resistance mechanism independent of canonical menin-MLL targets. We show that a group of noncanonical menin targets, which are bivalently cooccupied by active menin and repressive H2AK119ub marks, are typically downregulated after menin inhibition.
