Sphingosine‐1‐Phosphate Promotes FOS Activation in Osteosarcoma Under Tumor Acidosis

Acta Physiologica, Volume 242, Issue 6, June 2026.
ABSTRACT Aim The tumor microenvironment in solid tumors is characterized by extracellular acidosis, which promotes cancer aggressiveness. In osteosarcoma, the most common primary bone cancer, a highly acidic tumor microenvironment is associated with metastasis and poor prognosis, partly due to metabolic rewiring, including changes in lipid pathways ...

Targeting RTK signaling pathways in cancer [PDF]

, 2015
The RAS/MAP kinase and the RAS/PI3K/AKT pathways play a key role in the regulation of proliferation, differentiation and survival. The induction of these pathways depends on Receptor Tyrosine Kinases (RTKs) that are activated upon ligand binding.

RNA Modifications: Current Understandings and Future Perspectives

MedComm, Volume 7, Issue 5, May 2026.
Types of RNA modification. We have summarized the currently common types of RNA modifications, including ac4C, m6A, m1A, m5C, m3C, m7G, and ψ, and visually characterized their features through structural formulas. The characteristic structures are marked with a background color different from the background color.

Comorbid Alzheimer's Disease and Type 2 Diabetes Microbiota Shape Age‐Associated Gut–Brain Axis Profiles

Aging Cell, Volume 25, Issue 5, May 2026.
Fecal microbiota transplantation from elderly donors with Alzheimer's disease, type 2 diabetes, or both conditions into antibiotic‐treated mice revealed that comorbid microbiota produce the most severe dysbiosis and strongest suppression of hippocampal neurotrophic gene expression.

Human iPSC‐derived GABAergic interneuron transplantation restores circuit balance and cognitive function in an Alzheimer's disease model

Alzheimer's &Dementia, Volume 22, Issue 4, April 2026.
Abstract INTRODUCTION Alzheimer's disease (AD) is characterized by disrupted excitatory–inhibitory (E:I) balance and impaired synaptic function, yet current treatments fail to repair these fundamental circuit impairments. METHODS Human induced pluripotent stem cell‐derived post‐mitotic medial ganglionic eminence‐originated inhibitory neurons (MGE‐pINs)

Pathological Roles of Astrocytes in Traumatic Brain Injury

CNS Neuroscience &Therapeutics, Volume 32, Issue 4, April 2026.
TBI induces intrinsic astrocytic changes, including reactive astrogliosis, A1 and A2 polarization, ion channels activation, pathological edema, oxidative stress, and metabolic dysregulation. These injury‐responsive astrocytes regulate neuroinflammation and tissue remodeling through dynamic crosstalk with microglia, macrophages, vascular endothelial ...

EBV Genome Variations and Association With Diseases

Journal of Medical Virology, Volume 98, Issue 4, April 2026.
ABSTRACT The Epstein‐Barr virus (EBV) is associated with a range of diseases, including malignancies and autoimmune disorders. Driven by advances in deep sequencing technologies, recent studies have systematically characterized EBV genomic landscapes in diverse clinical specimens, uncovering distinct geographic patterns in strain distribution. However,
