Lifespan and Health Analysis

In Vivo Longevity Platform

InVivo Biosystems provides a streamlined Longevity Platform to determine whether a compound can extend lifespan, promote a longer healthspan, and test the outcome on signaling pathways and cellular mechanisms promoting longer life. We strive to understand the substance's mechanism of action and how it can impact human body in a senescence model.

We specialize in giving our clients a full picture of how each compound impacts several key pieces of the aging puzzle: the overall lifespan, the activity level and muscle use throughout senescence, and the underlying transcriptional markers of health. Senescence modeling enables us to understand a substance's mechanism of action on the process of aging.

Our data helps companies prioritize their development pipelines by giving them quantitative information about how candidate formulations combat aging and age-related conditions such as sarcopenia.

A Shortcut To Understanding Longevity: A Rapid In Vivo Analysis Of A Compound’s Effect On Health And Aging

Advantages

Gain Insights into the Mechanism of Action within 4 months

Traditional longevity experiments using mice can take upwards of 2-3 years to complete and cost hundreds of thousands of dollars. The InVivo Biosystems Longevity Platform is designed to:

  1. Quickly and economically test a compound’s ability to extend lifespan and healthspan in a whole animal model;
  2. Characterize the effect of the compound on known aging pathways including mitochondrial, oxidative stress, and DNA damage.

Aging pathway analysis. Global gene expression analysis indicates two candidate pathways likely to mediate the effect of compound on lifespan: oxidative phosphorylation and oxidative stress.

Comprehensive analysis from data collected over the entire lifespan of the animal

The InVivo Biosystems Longevity Platform produces a comprehensive analysis using the data collected over the entire lifespan of the adult animal. We use automated scanning to ensure smooth survival curves and more robust conclusions.

Our Approach

Our In-Vivo Longevity Platform is an effective approach to test the effects of a compound on lifespan, healthspan, and transcriptional changes related to aging. Our 3-step approach provides insights into the mechanism of action for lifespan and healthspan.

Step I:

Conduct a dose and toxicity assessment of the compound to determine whether a full longevity experiment is feasible and at what dosage. (Fig. 1)

Fig. 1

Dose-response curve to determine the stress level introduced by the compound. Day 1 adult worms were treated with Lu0128 at 1µM, 10µM, 100µM, 1mM, and 10mM for 12 hours. A) Xenobiotic stress biosensor response assay. B) Oxidative stress response assay. Calculated working EC50 = 21µM.

Step II:

Measure the lifespan and vitality extending effects of the compound by monitoring the adult animal’s survival, morphology and movement. The healthspan metrics are extracted from the same dataset as the lifespan readings.

Fig. 2

Assessing the eligibility of 2 promising compounds. (A) Compound A increases lifespan (orange) compared to untreated control. (B) In addition, exposure to compound A triggers a considerable improvement of healthspan, with 20-day old worms exposed to compound A exhibiting an overall activity level similar to untreated worms (grey) that are only 12-day old. Unlike control populations, worms exposed to compound A do not exhibits complete loss of activity prior to death. (C) Compound B also shows a strong longevity effect (purple), but (D) triggers a sharp, early decline in healthspan leading to a complete loss of locomotion by Day 23.

Step III:

Identify the aging pathways that contribute to the observed lifespan extension from Step II. Potentially identified pathways and mechanisms are identified, including genes related to mTOR, sirtuin, dietary restriction, oxidative stress.

Fig. 3

Measure changes in gene expression level. The gene asp-12 is downregulated 117-fold (p=1.3e-37) in the day 10 Lu0128 treated samples compared with the day 10 untreated. The gene lea-1 is upregulated 6.5-fold (p=2.4e-16) in the day 10 Lu0128 treated samples compared with the day 10 untreated.

Customer Testominal

"I really felt that InVivo Biosystems did pretty much everything that they said they would do. It was done in a manner that gave me confidence in the results. The communication and collaboration were as good as I've ever been a part of. If I wanted to do another study, I'd certainly have no problem coming back."  – Dr. David Vollmer, Chief Scientific Officer,  4Life Research. Read the customer story. >>

Service Packages

Our in-vivo Longevity Platform offers 3 service packages. Choose the package(s) that serves your needs the best.

  • Lifespan and healthspan analysis: produce lifespan and healthspan measurements by automatically monitoring an adult C. elegans’ survival, morphology and movement using the data collected over the entire lifespan of the adult C. elegans. 
  • Pathway analysis: identify the pathways that contribute to the observed lifespan extension using RNAseq or whole transcriptome sequencing (WTS).
  • Compound testing: determine a compound’s ability to extend lifespan and healthspan within 4 months once an experiment starts.

Frequently Asked Questions

The dose-finding test uses proprietary and patented C. elegans biosensor strains to monitor the physiological effect of a compound on the animal.

We monitor and measure the growth rate of animals from hatching to the first day of adulthood (total of 4 days).

WTS can be more cost-effective than qPCR to identify which genomic loci are expressed in a population at a given time over the entire expression range, hypothesis-free (without the need to pre-define the genes of interest). In addition, WTS yields high dimensional data for a large number of genomic loci and detects gene expression changes (i.e., mRNA levels) between different experimental conditions.

We accept crystals, emulsions, oils, nanoparticles or nanobeads up to 15 µm diameter.

We do not accept compounds that are hazardous and/or BSL 3 and above or any hazardous volatile compounds that require handling in a chemical hood.

Yes, however we recommend that a client provide either the compound itself or the specific catalog number(s) of the compound to be tested.

Three.

A positive and a negative control are included for each compound. The appropriate controls will be defined based on the nature of the compounds to be tested.
