Understanding of molecular mechanisms underlying hypothermia is of primary importance in devising strategies to diagnose hypothermia. We investigated the hypothalamic transriptome in hypothermia. For transcriptomic analyses, SuperSAGE, an improved method of serial analysis of gene expression, was used. Totally, 62,208 and 54,084 tags were collected from the hypothalami of normal and hypothermia, respectively. And 367 transcripts were differentially expressed at a statistically significant level. That is, 157 and 210 transcripts among them were expressed at a higher level in normal and hypothermic hypothalami. Results obtained by SuperSAGE and quantitative PCR were consistent in 6 selected genes, although levels of differences detected by the 2 methods were not exactly the same. mRNA expressions in the hypothalamus were considered to be useful for hypothermic diagnosis. Various methods have been applied for gene expression analyses and biomarker detections. However in forensic pathology, SuperSAGE would be a promising method, especially in gene discoveries and transcriptomic analyses.

Objective: This study aims to investigate how the E3 ubiquitin ligase LITAF influences mitochondrial autophagy by modulating MCL-1 ubiquitination, and its role in the development of epilepsy.
Methods: Employing single-cell RNA sequencing (scRNA-seq) to analyze brain tissue from epilepsy patients, along with high-throughput transcriptomics, we identified changes in gene expression. This was complemented by in vivo and in vitro experiments, including protein-protein interaction (PPI) network analysis, western blotting, and behavioral assessments in mouse models.
Post-transcriptional regulation of the transcriptional apparatus in neuronal development.

Post-transcriptional mechanisms, such as alternative splicing and polyadenylation, are recognized as critical regulatory processes that increase transcriptomic and proteomic diversity. The advent of next-generation sequencing and whole-genome analyses has revealed that numerous transcription and epigenetic regulators, including transcription factors and histone-modifying enzymes, undergo alternative splicing, most notably in the nervous system. Given the complexity of regulatory processes in the brain, it is conceivable that many of these splice variants control different aspects of neuronal development.

Introduction: Prenatal nicotine exposure (PNE) from maternal smoking disrupts regulatory processes vital to fetal development. These changes result in long-term behavioral impairments, including mood and anxiety disorders, that manifest later in life. However, the relationship underlying PNE, and the underpinnings of mood and anxiety molecular and transcriptomic phenotypes remains elusive.

Oil palm () yield is impacted by abiotic stresses, leading to significant economic losses. To understand the core abiotic stress transcriptome (CAST) of oil palm, we performed RNA-Seq analyses of oil palm leaves subjected to drought, salinity, waterlogging, heat, and cold stresses. A total of 19,834 differentially expressed genes (DEGs) were identified.

is a traditional Chinese medicinal herb rich in various bioactive secondary metabolites, such as alkaloids and flavonoids, and exhibits remarkable resistance to abiotic stress. The WRKY transcription factor (TF) family is one of the largest plant-specific TF families and plays a crucial role in plant growth, development, and responses to abiotic stress. However, a comprehensive genome-wide analysis of the WRKY gene family in has not yet been conducted.
