Automated phenotypic screening
Small-molecule kinase inhibitors have had success in the treatment of many diverse types of cancer. Here, we use Nanolive’s CX-A to test how cells respond to various inhibitors or modulators of kinase activities (Akt, JNK, CDK2, RTK, PKA, JAK, mTOR and AMPK). Images were taken using the automated 3×3 gridscan mode, at an acquisition rate of 1 scan every 25 mins, for 40 h.

Quantifying the response of cell populations to drug-perturbation with single cell resolution
Modifications in respiration underpin a plethora of diseases. In this video, we quantify the response of a cell population to Rotenone-perturbation (a chemical inhibitor of electron transfer in complex I of the respiratory chain). Images were taken for 24 h using the 10×10 grid-scan mode on Nanolive’s CX-A at an acquisition rate of one image taken every 8.5 mins.
Rotenone-perturbation (blue line, video top left) generates a larger amount of morphological noise in a cell population compared to unperturbed conditions (green line, data not shown). Increased variability is observed in cell extent (spikiness), dry mass, and granularity (texture; indicative of a change in internal composition).

Increasing biological relevance and simplifying the discovery workflow
These are the results of a case study that was created to demonstrate how the CX-A and Eve Analytics can be used in drug screening. We feature the entire process from image acquisition to data analysis and interpretation in our webinar here. In the case study, we test to what extent the art of observing influences the outcome of our experiments; something too often ignored when running live cell experiments. The video, shows the effects that four different treatments: (1) label-free; (2) cytotoxic (MitoTracker only); (3) cytotoxic and low phototoxic (MitoTracker and 1% laser power) and (4) cytotoxic and high phototoxic (MitoTracker and 5% laser power), have on cell health.
Gaining insights into a drugs mechanism of action
Nanolive’s content rich, multiplexed images bring target context to drug discovery, and so, can provide insights into a drugs mechanism of action. Here, we applied a drug and quantified how cells responded at the population level. One metric, granularity, was disproportionately impacted by the addition of the drug (Video 1). Granularity describes the texture of an image and so changes in this metric often reflect changes in the internal composition of the cell.
Video 1. Changes in granularity at the population level following drug-perturbation
Video 2. Changes in granularity at the single cell level following drug-perturbation
The sub-cellular resolution of Nanolive imaging allowed us to test this hypothesis at the single cell level (Video 2). The change in granularity clearly corresponds to a change in mitochondrial morphology; from a functional elongated state, to a dysfunctional, ring shape. This allowed us to hypothesize that our drug is acting on mitochondria, possibly on the respiratory chain, giving us precious insights into our drugs mechanism of action.

Feature Application: Drug Discovery
In this application note we demonstrate how the CX-A can be used for drug screening, target identification or mechanism of action studies. We feature the results of multiple, time-lapse imaging experiments featuring cells that have been perturbed by various anti-cancer drugs. We highlight the structural changes that the drugs have on cells and show that it is possible to analyze the images quantitatively.
Watch our Webinar: Accelerating oncology drug discovery with label-free imaging
In this webinar, Dr. Emma Gibbin, Communications Specialist at Nanolive will discuss the advantages of using label-free live cell imaging in the drug discovery process and show how Nanolive’s automated live cell imaging solution the CX-A, can be used to:
- observe unique drug-induced phenotypes that fluorescence microscopy cannot capture
- record dynamic cellular responses to drug perturbations
- automate in vitro screening studies.
Dr. Gibbin will present novel results from two experimental screens designed to test the phenotypic and morphological responses of pre-adipocyte and cancer cells to 8 inhibitors or modulators of kinase activity.
