The bidirectional relationship between cilia and PCP signaling pathway core protein Vangl2.

Vangl2, a core component of the PCP signaling pathway, serves as a scaffold protein on the cell membrane, playing a crucial role in organizing protein complexes. Cilia, dynamic structures on the cell surface, carry out a wide range of functions. Research has highlighted a bidirectional regulatory interaction between Vangl2 and cilia, underscoring their interconnected roles in cellular processes.

Semirational Protein Engineering of a Decarboxylative Aldolase for Regiodivergent and Stereodivergent Synthesis of Cyclic Imino Acids.

Aldolases are powerful C-C bond-forming enzymes for asymmetric organic synthesis because of their supreme stereoselectivity, diverse electrophiles and nucleophiles, and promising scalability. Stereodivergent engineering of aldolases to tune the selectivity for the synthesis of stereoisomers of chiral molecules is highly desirable but has rarely been reported. This study documented the semirational engineering of the decarboxylative aldolase UstD with the focused rational iterative site-specific mutagenesis (FRISM) strategy to perform a C-C bond-forming reaction with dione electrophiles.

Gradient experiment reveals physiological stress from heavy metal zinc on the economically valuable seaweed Sargassum fusiforme.

Zn is a common heavy metal pollutant in water bodies and accounts for the largest proportion of heavy metal pollutants in many rivers entering the sea. This study investigated the growth and physiological response characteristics of Sargassum fusiforme under different divalent Zn ion concentration gradients. We observed that low concentration Zn treatment (<2 mg L) exerted no significant effect on the growth rate, photosynthesis, and nitrogen metabolism-related indicators of S.

Genomic characterization reveals distinct mutational landscape of acral melanoma in East Asian.

Acral melanoma, the most common melanoma subtype in East Asia, is associated with a poor prognosis. This study aims to comprehensively analyze the genomic characteristics of acral melanoma in East Asians. We conduct whole-genome sequencing of 55 acral melanoma tumors and perform data mining with relevant clinical data.

Atomic Gap-State Engineering of MoS for Alkaline Water and Seawater Splitting.

Transition-metal dichalcogenides (TMDs), such as molybdenum disulfide (MoS), have emerged as a generation of nonprecious catalysts for the hydrogen evolution reaction (HER), largely due to their theoretical hydrogen adsorption energy close to that of platinum. However, efforts to activate the basal planes of TMDs have primarily centered around strategies such as introducing numerous atomic vacancies, creating vacancy-heteroatom complexes, or applying significant strain, especially for acidic media. These approaches, while potentially effective, present substantial challenges in practical large-scale deployment.
