Service Description

The InVivo Longevity Platform is our validated platform managed by experienced PhD scientists who understand your research needs and can accelerate your progress by generating a large sample size.

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

We specialize in giving our clients a full picture of how each compound or test article 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. Our detailed data reports set us apart.

  • Translatable Lifespan. Our longevity readout provides both a Kaplan-Meier estimate of survival and a hazard rate curve – two functions that are the industry standard for modeling survival and are widely used in worm, mouse, and human studies.
  • Genetic Signature. Our platform gives information about how the genetic pathways are regulated in response to the compound, which can provide patentable information about the MoA.
  • Export Reports and Access. Our reports deliver graphs that are Marketing & IP ready. We pride ourselves on the thoroughness and interpretability of the results.
  • Experts on Tap. All our projects include on-call project status updates, as well as regularly scheduled communication.  We also provide on-call consulting and interpretation with our Ph.D. level, subject-matter experts.

Kaplan-Meier curve showing the effects of two compounds on the lifespan of a population of animals. The curve depicts the decline in population as time progresses. The population is assessed 3 times each hour for 40 days. Animals treated with Compound A have a significantly longer lifespan than the animals treated with vehicle control. Animals treated with Compound B have a shortened lifespan.

Lifespan vs. Healthspan:

Lifespan data are needed to make claims on a compound's ability to extend longevity. The data are generated from following the animals for the entirety of their lifespan. When only healthspan data is provided, it often does not follow the animals for the entirety of the life and longevity claims remain unsubstantiated.

Service Packages

Our in-vivo Longevity Platform offers 3 service packages. Choose the package(s) that serves your needs the best. We don't offer step 2 or step 3 as stand-alone packages.

Advantages

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

Traditional longevity experiments using mice can take upwards of 2-3 years to complete and cost hundreds of thousands of dollars. Using our platform, you can quickly and economically test a compound’s ability to extend lifespan and healthspan with large sample sizes of live animals in less than 5 months and get answers to the following questions:

  • Does my compound have a positive or negative effect on lifespan?
  • How does my compound affect lifespan AND healthspan?
  • Which are the associated signaling pathways that contributed to the life extension?

Get Kaplan-Meier survival curves from live animals within 5 months.

Using our platform, you can quickly and economically test a compound’s ability to extend lifespan and healthspan with large sample sizes of live animals. We use automated scanning to produce smooth, high resolution survival curves and ensure reproducibility, detection power, high resolution and robust conclusions.

Leverage Molecular Biology to Understand Mechanism of Action.

We use RNAseq to help our clients get the “big picture” effect of their compound on known aging pathways including mitochondrial stress, oxidative stress, and DNA damage. By comparing the complete gene expression profile of animals as they age, we can uncover how compounds exert their lifespan-extending effects.

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.

Pathway components are color coded based on the level of up or down regulation of treated samples versus control. 

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: Dose Finding 

Viability, Growth, and Development assays are used to determine toxicity levels in C. elegans.

Right: Day 3 snapshot of worm development including embryonic lethality (black).

Step II: Measuring lifespan

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

Aggregate motility and morphology analysis over duration of lifespan. Representative data from worms treated with either vehicle (Control) or a compound that improves healthspan (Drug).  All measures are obtained by averaging data for all worms detected on a plate, then averaging across different replicate plates of the same condition. All measurements are based on worms that are still alive and moving at the time of quantification. Motility measures are normalized to fall between 0 and 100.

Step III: Identifying Aging Pathways

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.

Mapping of gene expression data to longevity pathways in the KEGG database. Pathway shown represents changes of expression that might be observed under conditions of dietary restriction. Pathway components are color coded based on the level of up or down regulation of treated samples versus control. 

This method holistically maps gene expression data to both established longevity pathways and peripheral pathways that support longevity. Colored score increments indicate level of up-(red) or down-(blue) regulation weighted by the statistical significance. Solid lines indicate direct pathway connections and dashed lines indicate indirect or multi-step connections. Where lists of many differentially-expressed genes have been condensed into a module, the number of genes is indicated.

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.

Frequently Asked Questions

To find an optimal dosage for longevity testing, we apply

  1. a highly-sensitive growth assay to find physiologically effective dose range,
  2. an acute toxicity assay to determine maximum non-toxic dose, and
  3. our extensive knowledge base of compound testing in C. elegans.

We share our data and rationale with the client in advance of finalizing dosage and delivery for longevity assays.

We monitor and measure the growth rate of animals exposed to compound from hatching to the first day of adulthood (total of 4 days) using precise, automated image analysis.  Nematode growth rate and development is highly sensitive to chemical disturbances, and the growth assay is widely used in toxicology studies.

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, solutions, emulsions, oils, natural extracts, 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.
