We describe a methodology to perform genetic analysis in Chlamydia based on chemical mutagenesis and whole genome sequencing. In addition, a system for DNA exchange within infected cells is described that can be used for genetic mapping. This method may be broadly applicable to microbial systems lacking transformation systems and molecular genetic tools.

A Reverse Genetic Approach to Test Functional Redundancy During Embryogenesis

Gene function can be obscured in loss-of-function experiments if there is compensation by another gene. The zebrafish model provides a relatively high-throughput means to reveal such functional redundancy in living embryos.

Genetic Screens

Genetic screens are critical tools for defining gene function and understanding gene interactions. Screens typically involve mutating genes and then assessing the affected organisms for phenotypes of interest. The process can be “forward”, where mutations are generated randomly to identify unknown genes responsible for the phenotypes, or it can be “reverse”, where specific genes are targeted for mutation to observe what phenotypes are produced.Here, JoVE reviews various types of genetic...

Reverse Genetic Approach to Identify Regulators of Pigmentation using Zebrafish

2022
Regulators of melanocyte functions govern visible differences in the pigmentation outcome. Deciphering the molecular function of the candidate pigmentation gene poses a challenge. Herein, we demonstrate the use of a zebrafish model system to identify candidates and classify them into regulators of melanin content and melanocyte number.

An Overview of Genetics and Disease

Many human diseases are associated with mutations or variations in genetic sequences. Some of these genetic variants are heritable, passed down from generation to generation, while others arise sporadically during an organism’s life and cause diseases such as cancer. Researchers are trying to identify and characterize these genetic alterations in the hopes of improving diagnosis and therapeutic options for patients.In this video, we will examine the history of genetic disease research, and...

These strategies work by changing the biological conditions that sustain disease rather than by altering inherited sequence information. Drugs and antibodies can influence signaling pathways or immune responses, while devices and lifestyle changes can modify cellular activity or tissue conditions. The relevant mechanism therefore depends on the intervention and clinical goal, making the approach adaptable across different medical problems.
Drugs and antibodies can alter signaling pathways or immune responses, whereas devices and lifestyle changes can influence tissue conditions or broader cellular activity. Because these components act through different routes, the expected effect depends on which disease-related process is targeted. The category of intervention alone does not determine the mechanism or clinical outcome.
A non-genetic approach may be considered when genetic therapies are unsuitable, unavailable, or still under development. Its practical value is not limited to one disease class: clinicians can select interventions according to whether the goal is prevention, diagnosis, symptom management, or therapy. This flexibility allows care to focus on the disease-related process requiring change.
Selection starts with the disease-related process that needs to be changed and the intended clinical goal. Prevention, diagnosis, symptom management, and therapy may require different types of intervention, including drugs, antibodies, devices, lifestyle changes, or other treatments. This goal-directed choice keeps the treatment strategy connected to the physiological problem and the outcome clinicians seek.
They can support prevention and diagnosis as well as symptom management and therapy. That range matters because the same broad strategy is not restricted to reversing disease after it appears. Depending on the medical context, an intervention may help identify a condition, reduce symptoms, alter a disease-related process, or support efforts to prevent illness.
They give researchers a way to study disease-related changes without directly modifying DNA or introducing genetic material. Observed outcomes can therefore help separate effects linked to gene regulation from those produced by broader physiological or environmental changes. This makes the approaches useful not only as treatments, but also as tools for interpreting how disease processes respond to intervention.
