Presented here is a protocol to study pharmacological responses in prostate epithelial organoids. Organoids closely resemble in vivo biology and recapitulate patient genetics, making them attractive model systems. Prostate organoids can be established from wildtype prostates, genetically engineered mouse models, benign human tissue, and advanced prostate cancer.

Zebrafish represent a powerful vertebrate model that has been under-utilised for metabolic studies. Here we describe a rapid way to measure the in vivo metabolic profile of developing zebrafish that allows the comparison of different mitochondrial function parameters between genetically or pharmacologically manipulated embryos, thereby increasing the applicability of this organism.

An attractive model for studying stem cell differentiation within a live animal is the planarian flatworm. Regeneration is studied by simple amputation experiments that are easily performed in a basic laboratory and are amenable to pharmacological and genetic (in vivo RNAi) manipulation as detailed by protocols in this article.

Expression Profiling with Microarrays

Microarrays are important tools for profiling gene expression, and are based on complementary binding between probes that are attached to glass chips and nucleic acids derived from samples. Using these arrays, scientists can simultaneously evaluate the expression of thousands of genes. In addition, the expression profiles of different cells or tissue types can be compared, allowing researchers to deduce how the expression of different genes change during biological processes, and thus gain...

Loss of the righting reflex has long served as a standard behavioral surrogate for unconsciousness, also called hypnosis, in laboratory animals. Alterations in volatile anesthetic sensitivity caused by pharmacological interventions can be detected with a carefully controlled high-throughput assessment system, which may be adapted for delivery of any inhaled therapeutic.
FAQs
Potency indicates the concentration range at which a compound produces an effect, whereas selectivity describes how preferentially it acts on one biological target or pathway rather than others. Considering both measures helps distinguish strong but broadly acting compounds from those with more targeted activity. This comparison supports candidate selection and clarifies whether observed cellular or organism-level effects align with the intended mechanism.
Testing across concentrations and experimental conditions shows how consistently a compound produces its effects and whether responses change as exposure changes. These comparisons help researchers connect target interactions with pathway activity, potency, and toxicity rather than relying on a single measurement. The resulting response profile provides a more informative basis for evaluating performance, safety, and reproducibility.
Pharmacological profiling links measurements at different biological levels, from target binding and pathway activity to effects in cells or organisms. This connection allows bioengineers to evaluate whether a molecular interaction produces the intended functional response in a biological system. Such evidence is useful when designing engineered tissues, disease models, biosensors, or delivery systems that must reflect drug activity.
A workflow can combine assays measuring target binding, pathway activity, potency, selectivity, and toxicity. Researchers compare these measurements across concentrations and experimental conditions to assemble a response profile rather than interpreting one assay in isolation. This integrated approach helps relate molecular activity to broader biological effects and supports decisions about candidate quality, mechanism of action, and safety.
In bioengineering, profiling data help determine how a compound’s molecular and functional effects should inform the design of drug-delivery systems and engineered tissues. Measurements of potency, selectivity, pathway activity, and toxicity provide evidence for evaluating whether a system produces the desired biological response. The same information can also guide the refinement of disease models and biosensors.
Researchers use pharmacological profiling when comparing bioactive compounds, investigating mechanisms of action, or assessing potential safety concerns. A compound’s combined response profile can reveal its activity, selectivity, potency, and toxicity across tested conditions, supporting more informed candidate selection. These data may also reduce reliance on less predictive testing models by connecting molecular behavior with cellular or organism-level outcomes.
