Ubiquitination is a post-translational modification process that involves various biological processes, including signal transduction, cell cycle regulation, cell stress responses, and cell apoptosis. It plays a crucial role in maintaining protein homeostasis, regulating various biological reactions in cells, and ensuring the normal physiological functions of organisms. Immunoprecipitation is a ...
Ribonucleases (RNases) represent a critical class of enzymes with a principal role in the degradation of RNA, crucial for maintaining cellular homeostasis and regulating gene expression. By cleaving RNA molecules, RNases are integral to numerous biological processes, ranging from RNA maturation to the innate immune response against RNA viruses. In this exploration, we delve into the multifaceted ...
Histone SUMOylation is a post-translational modification that involves the covalent linking of the SUMO protein to the lysine residues of histones. This process requires the participation of a series of enzymes, including E1 activating enzyme, E2 conjugating enzyme and E3 ligase. SUMOylation plays a key role in gene expression regulation, DNA repair, RNA processing and nuclear transport in the ...
Post-translational modifications (PTMs) of histones are crucial for protein structure regulation, playing key roles in gene expression regulation, DNA repair, cell signaling, and more. These PTMs of histones can be achieved by adding or removing different chemical groups or proteins, thus affecting chromatin structure and function. Here are some common types of histone PTMs. 1. Acetylation The ...
MicroRNAs (miRNAs) are a type of small single-stranded non-coding RNA molecules of 18 ~ 24 nucleotide (nt) in length. MiRNAs have been found in many species including plants, animals and some viruses. The conventional biosynthesis pathway consists of four steps: 1) miRNA genes are transcribed by RNA Polymerase II or III to produce pri-miRNAs, 2) pri-miRNAs are recognized and cleaved by ...
What Are DEGs in Genetics? DEGs, or Differentially Expressed Genes, are genes whose expression levels show significant differences between two or more conditions or experimental groups. In genetics and genomics research, gene expression refers to the process by which information encoded in a gene's DNA sequence is converted into functional proteins or RNA molecules. When studying gene ...
What are Differentially Expressed Genes (DEGs) in Genetics? Differentially Expressed Genes (DEGs) are genes that exhibit significant differences in expression levels between two or more conditions or experimental groups. In genetics and genomics research, gene expression refers to the process through which the information encoded in a gene's DNA sequence is transformed into functional proteins ...
Welcome to our newest blog series where we investigate Amyotrophic Lateral Sclerosis (ALS) using our AI knowledge mapping tools. Check back for our next installment, in which we analyze transcriptomics from spinal cord samples collected from patients as well as a mouse model. In this post, we will continue to explore publicly available datasets surrounding Amyotrophic Lateral Sclerosis ...

Since the 19th century, the practice of tissue processing has remained largely unchanged, resulting in solidified, paraffin-embedded tissue blocks for sectioning. As staining procedures have advanced and immunohistochemistry is becoming more widely used, high-quality tissue sections are paramount for accurate interpretation of disease ...
Diamine oxidase (DAO) is an intracellular enzyme that catalyzes diamine in mucosal or ciliated epithelial cells of the mammalian small intestine. It protects the intestinal mucosa by regulating intracellular ion homeostasis, influencing conduction pathways, and promoting cellular repair. Serum DAO is elevated in small intestinal mucosal barrier failure or in intestinal mucosal cell necrosis; ...
Mitochondria are dynamic organelles with bilayer membranes. Mitochondria have multiple functions, not only providing energy to cells through oxidative phosphorylation to produce ATP, but also involved in regulating processes such as calcium homeostasis, reactive oxygen species (ROS) production, cellular stress response and cell death. Mitochondria play a key role in maintaining cellular health ...
It is an efficient way to regulate molecular function by applying specific chemical modifications on biological molecules. This article highlights the current heated pseudoUridine modification in RNA, which suggests new possibilities for novel drug or vaccine discovery. An Introduction to PseudoUridines PseudoUridine (Ψ) is a post-transcriptional RNA modification that alters RNA-RNA and ...
Scientists at the Scripps Research Institute have found that the immune protein CSF1 may cause anxiety during alcohol withdrawal. Some nuclei have the corticotropin-releasing factor receptor 1 crhr1 gene, and the glutamate transporter slc17a7 gene, but the glutamate decarboxylase gene gad2 does not, suggesting that they mainly constitute an excitatory population in the medial prefrontal cortex. ...
“There was a constant chattering in my brain. It was my own voice talking about depression, agony, hopelessness,” said Deirdre Lehman, a woman in her 60s who had tenuously contended with bipolar disorder for over a decade. After receiving groundbreaking depression treatment, Deirdre went on to describe the relief as follows: “By lunch, I could look my husband in the ...
Lipids are a class of metabolites with diverse chemical structures. More than just components of cell membranes and energy storage substances, lipids can perform a variety of important biological functions in life activities. The structural diversity of lipids endows them with a variety of important biological functions: (1) they constitute an important component of the cell membrane. Many ...
Part II: Understanding familial and sporadic ALS Welcome to our newest blog series where we investigate Amyotrophic Lateral Sclerosis (ALS) using our AI knowledge mapping tools. Check back for our next installment, in which we analyze transcriptomics from spinal cord samples collected from patients as well as a mouse model. In this second post in our Exploring ALS series, we will begin to dig ...

Changes in tissue transcriptomes and productivity of Arabidopsis thaliana were investigated during exposure of plants to two widely used engineered metal oxide nanoparticles, titanium dioxide (nano‐titanium) and cerium dioxide (nano‐cerium). Microarray analyses confirmed that exposure to either nanoparticle altered the transcriptomes of rosette leaves and roots, with comparatively larger ...
As a representative species of nematodes, Caenorhabditis elegans is an attractive animal model for evaluating ecotoxicological effects and intrinsic mechanisms of stress response in vivo. To acquire a better knowledge of environmental effects of bisphenol A (BPA), ecotoxicological evaluations were conducted using C. elegans upon the physiological (growth, locomotion behaviors, and ...
Tobacco can easily accumulate certain heavy metals in leaves and thus poses a potential threat to human health. To systematically dissect Cr-responsive miRNAs and their targets at the global level, four small RNA libraries were constructed from the roots of Cr-treated (Cr) and Cr-free (control) two contrasting tobacco genotypes,Yunyan2 (Cr-sensitive) and Guiyan1 (Cr-tolerant). Using ...
Arsenic, a natural element of ecological relevance, is found in natural water sources throughout Argentina in concentrations between 0.01 and 15 mg/L. The autochthonous toad Rhinella arenarum was selected to study the acute toxicity of As and the biochemical responses elicited by the exposure to As in water during its embryonic development. The LC50 value averaged 24.3 mg/L As and remained ...
