Article Abstract
Dormancy-growth cycles are crucial for seasonal adaptation in long-lived trees, yet the underlying mechanisms remain poorly understood despite decades of research. A recent study by Pandey et al. revealed a key mechanism, low-temperature-regulated opening of plasmodesmata (PD), providing new insight into how cell-cell communication controls dormancy release.

Assessing the impact of perfluoroalkyl substances on liver health: a comprehensive study using multi-donor human liver spheroids.

Background: Although per- and polyfluoroalkyl substances (PFAS) have been linked to chronic liver diseases, the specific cellular and molecular mechanisms by which different PFAS contribute to human liver dysfunction remain unclear. This study aims to elucidate those mechanisms.
Methods: We exposed a multi-donor human liver spheroid model composed of multiple cell types to 20 µM of PFHxS, PFOA, PFOS, or PFNA for seven days, followed by single-cell RNA sequencing and lipid staining.
Single-Cell Transcriptome Profiling Reveals Dynamic Cell Populations and Immune Infiltration in Moyamoya Disease.

Background: The cellular composition and molecular mechanisms of the pathological arteries in Moyamoya disease (MMD) remain poorly understood. To improve our understanding of pathogenesis in MMD, we aimed to comprehensively map the cellular composition and molecular alterations within the pathological arteries of patients with MMD.
Methods: Superficial temporal artery samples were collected from patients with MMD (n=2) and healthy controls (n=3), yielding a total of 26 371 cells that were used for single-cell RNA sequencing.

Background: Interleukin-1 receptor-like 1 (IL1RL1, also known as ST2) plays a critical role in immune regulation. Pan-cancer analysis has revealed that IL1RL1 is closely associated with cellular immune functions; however, its role in clear cell renal cell carcinoma (ccRCC) and the tumor microenvironment (TME) remains poorly defined.
Methods: We analyzed IL1RL1 expression patterns using data from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) databases.

Introduction: Childhood acute lymphoblastic leukemia (cALL), the most common pediatric hematologic malignancy, arises primarily from B-cell origin and is strongly associated with immune dysfunction. This article integrated single-cell and bulk transcriptomic data to identify key B-cell subsets and cALL-related molecules as biomarkers.
Methods: Single-cell RNA sequencing (scRNA-seq) Data from 2 pre-B high hyperdiploid (HHD) ALL patients and 3 healthy pediatric bone marrow samples (GSE132509) were utilized for cell clustering using the Seurat package.
The diverse pigmentation patterns of animals are crucial for predation avoidance and behavioral display, yet mechanisms underlying this diversity remain poorly understood. In zebrafish, Turing models have been proposed to explain stripe patterns, but it is unclear if they apply to other fishes. In anemonefish ( , we identified , a gene orthologous to zebrafish and encoding a connexin involved in pigment cell communication, as responsible for the phenotype.
