Structure of a human intramembrane ceramidase explains enzymatic dysfunction found in leukodystrophy

Nature Communications, 2018
Alkaline ceramidases (ACERs) are a class of poorly understood transmembrane enzymes controlling the homeostasis of ceramides. Here authors solve the Xray structure of human ACER3 and uncover a Ca2+ binding site providing an explanation for the known ...

Nutritional Regulation of IGF-I and IGF Binding Proteins

Annual Review of Nutrition, 1991
"The insulin-like growth factors (IGF-I and IGF-II) are small polypeptides (Mr -7500) that control growth of multiple cell types. Cells derived from all three embryonic lineages contain IGF receptors, and almost all cell types have been shown to respond to IGFs (79).

IGF-I receptor phosphorylation is impaired in cathepsin X-deficient prostate cancer cells [PDF]

, 2012
The cysteine-type peptidase cathepsin X is highly upregulated in several cancers and presumably promotes tumor invasion through bypassing cellular senescence. Here, we present first evidence that the underlying mechanism may involve the regulation of the

FTO-mediated cytoplasmic m6Am demethylation adjusts stem-like properties in colorectal cancer cell

Nature Communications, 2021
The demethylase FTO was shown to remove on N6-methyladenosine (m6A) and N6, 2’-O-dimethyladenosine (m6Am) modifications on RNAs. Here the authors show that FTO impedes cancer stem cell-like abilities in colorectal cancer cells through its m6Am ...

GLP-1 and GIP receptors signal through distinct β-arrestin 2-dependent pathways to regulate pancreatic β cell function

Cell Reports, 2023
Summary: Glucagon-like peptide 1 (GLP-1R) and glucose-dependent insulinotropic polypeptide (GIPR) receptors are G-protein-coupled receptors involved in glucose homeostasis. Diabetogenic conditions decrease β-arrestin 2 (ARRB2) levels in human islets.

IGF-1 Gene Polymorphism and its Association with Cashmere Fiber Trait in Changthangi Goats

Journal of Natural Fibers, 2020
The Cashmere (Pashmina) fiber attracts great demand worldwide for its fineness. To identify and determine the role of Insulin-like Growth Factor-1 (IGF-1) gene polymorphism on Pashmina fiber traits (quality and quantity), exon IV, and part of intron IV ...

Mouse spinal cord cellular mapping of dopamine D2 receptors-containing cells

Frontiers in Neuroanatomy
The spinal cord (SC) serves as the primary relay for sensory information originating in the periphery and transmitted to the brain for processing. Sensitive primary afferent fibers project to the dorsal horn, which contains a highly diverse array of ...
