Serum GFAP and UCH-L1 Levels for the Assessment of the Absence of Hemorrhagic Transformation: A Multicenter Prospective Cohort Study.

Background: Currently, validated biomarkers for assessing hemorrhagic transformation (HT) after intravenous thrombolysis (IVT) are lacking. We aimed to validate a test combining GFAP (glial fibrillary acidic protein) and UCH-L1 (ubiquitin C-terminal hydrolase-L1) to indicate the absence of HT after IVT.

Methods: We prospectively enrolled consecutive patients with stroke treated with IVT from 16 hospitals.

Sodium oligomannate disrupts the adherence of Rib bacteria to gut epithelia to block SAA-triggered Th1 inflammation in 5XFAD transgenic mice.

Sodium oligomannate (GV-971), an oligosaccharide drug approved in China for treating mild-to-moderate Alzheimer's disease (AD), was previously found to recondition the gut microbiota and limit altered peripheral Th1 immunity in AD transgenic mice. As a follow-up study, we here made advances by pinpointing a Lactobacillus murinus (L.m.

Preclinical efficacy of the potent, selective menin-KMT2A inhibitor JNJ-75276617 (bleximenib) in KMT2A- and NPM1-altered leukemias.

The interaction between menin and histone-lysine N-methyltransferase 2A (KMT2A) is a critical dependency for KMT2A- or nucleophosmin 1 (NPM1)-altered leukemias and an emerging opportunity for therapeutic development. JNJ-75276617 (bleximenib) is a novel, orally bioavailable, potent, and selective protein-protein interaction inhibitor of the binding between menin and KMT2A. In KMT2A-rearranged (KMT2A-r) and NPM1-mutant (NPM1c) acute myeloid leukemia (AML) cells, JNJ-75276617 inhibited the association of the menin-KMT2A complex with chromatin at target gene promoters, resulting in reduced expression of several menin-KMT2A target genes, including MEIS1 and FLT3.

Negative Selection Allows DNA Mismatch Repair-Deficient Mouse Fibroblasts to Tolerate High Levels of Somatic Mutations.

Substantial numbers of somatic mutations have been found to accumulate with age in different human tissues. Clonal cellular amplification of some of these mutations can cause cancer and other diseases. However, it is as yet unclear if and to what extent an increased burden of random mutations can affect cellular function without clonal amplification.

Development of a First-in-Class RIPK1 Degrader to Enhance Antitumor Immunity.

The scaffolding function of receptor interacting protein kinase 1 (RIPK1) confers intrinsic and extrinsic resistance to immune checkpoint blockades (ICBs) and has emerged as a promising target for improving cancer immunotherapies. To address the challenge posed by a poorly defined binding pocket within the intermediate domain, we harnessed proteolysis targeting chimera (PROTAC) technology to develop a first-in-class RIPK1 degrader, LD4172. LD4172 exhibited potent and selective RIPK1 degradation both and .

Hierarchically Aligning 10 Legume Genomes Establishes a Family-Level Genomics Platform.

Mainly due to their economic importance, genomes of 10 legumes, including soybean (), wild peanut ( and ), and barrel medic (), have been sequenced. However, a family-level comparative genomics analysis has been unavailable. With grape () and selected legume genomes as outgroups, we managed to perform a hierarchical and event-related alignment of these genomes and deconvoluted layers of homologous regions produced by ancestral polyploidizations or speciations.

Methyl-CpG-binding domain protein MBD7 is required for active DNA demethylation in Arabidopsis.

Although researchers have established that DNA methylation and active demethylation are dynamically regulated in plant cells, the molecular mechanism for the regulation of active DNA demethylation is not well understood. By using an Arabidopsis (Arabidopsis thaliana) line expressing the Promoter RESPONSIVE TO DEHYDRATION 29A:LUCIFERASE (ProRD29A:LUC) and Promoter cauliflower mosaic virus 35S:NEOMYCIN PHOSPHOTRANSFERASE II (Pro35S:NPTII) transgenes, we isolated an mbd7 (for methyl-CpG-binding domain protein7) mutant. The mbd7 mutation causes an inactivation of the Pro35S:NPTII transgene but does not affect the expression of the ProRD29A:LUC transgene.
