Article Abstract

Phosphatidylinositide 3-kinase (PI3K) γ is the only class IB PI3K member playing significant roles in the G-protein-dependent regulation of cell signaling in health and disease. Originally found in the immune system, increasing evidence suggest a wide array of functions in the whole organism. PI3Kγ occur as two different heterodimeric variants: PI3Kγ (p87) and PI3Kγ (p101), which share the same p110γ catalytic subunit but differ in their associated non-catalytic subunit. Here we concentrate on specific PI3Kγ features including its regulation and biological functions. In particular, the roles of its non-catalytic subunits serving as the main regulators determining specificity of class IB PI3Kγ enzymes are highlighted.

Background: Alzheimer's disease (AD) patients and animal models exhibit an altered gut microbiome that is associated with pathological changes in the brain. Intestinal miRNA enters bacteria and regulates bacterial metabolism and proliferation. This study aimed to investigate whether the manipulation of miRNA could alter the gut microbiome and AD pathologies.

Background: Gastric cancer is one of the most common cancers worldwide, with its prognosis influenced by factors such as tumor clinical stage, histological type, and the patient's overall health. Recent studies highlight the critical role of lymphatic endothelial cells (LECs) in the tumor microenvironment. Perturbations in LEC function in gastric cancer, marked by aberrant activation or damage, disrupt lymphatic fluid dynamics and impede immune cell infiltration, thereby modulating tumor progression and patient prognosis.

Background: Most RNA-seq datasets harbor genes with extreme expression levels in some samples. Such extreme outliers are usually treated as technical errors and are removed from the data before further statistical analysis. Here we focus on the patterns of such outlier gene expression to investigate whether they provide insights into the underlying biology.

Histone arginine methylation by protein arginine methyltransferases (PRMTs) is crucial for transcriptional regulation and is implicated in cancers. Despite their therapeutic potential, some PRMTs present challenges as drug targets due to their context-dependent activities. Here, we demonstrate that hypoxia triggers the rapid condensation of PRMT2, which is essential for its histone H3R8 asymmetric dimethylation (H3R8me2a) activity.

Engineering resistance genes against tomato brown rugose fruit virus.

Tomato brown rugose fruit virus (ToBRFV) overcomes all known tomato resistance genes, including the durable Tm-2, posing a serious threat to global tomato production. Here, we employed in vitro random mutagenesis to evolve the Tm-2 leucine-rich repeat (LRR) domain and screened ∼8,000 variants for gain-of-function mutants capable of recognizing the ToBRFV movement protein (MP) and triggering hypersensitive cell death. We identified five such mutants.
