Nutrient perception refers to the ability of cells to recognize and respond to energy substrates, such as glucose, fatty acids, and ketones. Nutrient sensing pathways play a crucial role in regulating cellular metabolism, growth, and survival. Dysregulated nutrient sensing is a hallmark of aging and is associated with various age-related diseases, including metabolic disorders, neurodegenerative diseases, and cancer. At CD BioSciences, we are committed to providing comprehensive analysis services for studying dysregulated nutrient sensing during aging.

Critical Nutrient Sensing Pathway Analysis Services We Offer
Analysis of insulin/IGF-1 signaling pathway in aging
In mammals, insulin/IGF-1 signaling is an important coordinator of nutrient availability with energy homeostasis and metabolic processes, which is activated by insulin-like peptide (ILP) ligands in response to nutrient availability.
Using advanced molecular techniques, we examine crucial constituents of the insulin/IGF-1 signaling pathway, encompassing insulin receptors, insulin-like growth factor receptors, downstream signaling molecules, and transcription factors. By investigating the expression levels, post-translational modifications, and activity of these constituents, we can detect anomalous signaling events and potential treatment targets for age-related metabolic disorders.
Analysis of the mTOR pathway in aging
The mTOR pathway serves as a pivotal controller of cellular growth and metabolism by regulating nutrient availability and energy status. We employ cutting-edge methods to examine the activity, protein expression, and positioning of crucial elements like mTOR complexes, upstream regulators, and downstream effectors within the mTOR pathway. Our services provide a means to gain insight into the underlying mechanisms of age-related diseases and to identify potential therapeutic targets for intervention.
Analysis of the AMPK pathway in aging
The AMP-activated protein kinase (AMPK) pathway is a cellular energy sensor that regulates energy homeostasis and metabolism. Through advanced molecular techniques, we analyze the activity, protein expression, and phosphorylation status of key components of the AMPK pathway, including AMPK subunits, upstream kinases, and downstream targets. Based on studying the dysregulation of the AMPK pathway, we can gain insights into the metabolic changes associated with aging and identify potential therapeutic targets for age-related metabolic disorders.
Our Workflow of Analyzing Dysregulated Nutrient Sensing During Aging
- Study design
We collaborate closely with our clients to design studies that address their specific research questions and objectives. We help our clients select aging cellular models and animal models to study the impact of dysregulated nutrient sensing on aging-related phenotypes.
- Molecular analysis
Firstly, we help our clients analyze and identify the specific nutrient-sensing pathways (e.g., mTOR, insulin/IGF-1, AMPK, sirtuins) based on their relevance to aging and associated dysregulation. Then, we measure the expression and activity of key proteins and metabolites involved in the selected nutrient-sensing pathways. We also investigate genetic and epigenetic alterations and metabolic profiling associated with dysregulated nutrient sensing during aging.
- Data analysis and interpretation
We utilize bioinformatic tools and systems biology approaches to analyze complex datasets. We provide in-depth data interpretation, including pathway analysis, functional annotation, and identification of key regulatory networks associated with dysregulated nutrient sensing during aging.
