Osmoregulation in Fishes

Osmoregulation in Fishes

When cells are placed in a hypotonic (low-salt) fluid, they can swell and burst. Meanwhile, cells in a hypertonic solution—with a higher salt concentration—can shrivel and die. How do fish cells avoid these gruesome fates in hypotonic freshwater or hypertonic seawater environments?

Mouse Models of Cancer Study

Mouse Models of Cancer Study

Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...

FISH - Fluorescent In-situ Hybridization

FISH - Fluorescent In-situ Hybridization

Fluorescence in situ hybridization, or FISH, was developed in the early 1980s and has quickly become one of the most widely used techniques in cytogenetics. Labeled probes are used to bind complementary DNA or RNA sequences on a chromosome or in a region within a cell. Earlier, the probes could only be obtained by cloning or reverse transcription of a DNA template. Currently, the probe oligonucleotides can be synthesized synthetically. Additionally, with the advancement of optical techniques,...

Cancer

Cancer

Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

What is Cancer?

What is Cancer?

Cells and tissues must meticulously coordinate their activities for the normal functioning of the human body. Therefore, they exhibit socially responsible behavior - resting, growing, dividing, differentiating, or dying - for the organism’s benefit. Cancer arises when cells divide uncontrollably and invade other tissues or organs.
Although people have known about cancer for centuries, it was only in 1761 that Giovanni Morgagni of Padua performed a detailed autopsy of...

Cancer Vaccines

Cancer Vaccines

Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

Background:

Cancer is a leading cause of mortality in the US, alongside heart disease.
Despite advances in organoids and xenografts, model organisms remain crucial for cancer research due to their genetic tools, rapid discovery pace, and cost-effectiveness.
Model organisms allow for the analysis of both the tumor and its microenvironment, which is vital for understanding metastasis and drug resistance.

Purpose of the Study:

To explore the strengths of fruit flies and zebrafish in addressing fundamental cancer biology questions.
To highlight the contribution of these model organisms in identifying potential therapeutic candidates for cancer treatment.

Main Methods:

Utilizing genetic tools in fruit flies (Drosophila melanogaster) for cancer research.
Employing zebrafish (Danio rerio) models to study tumor microenvironment and metastasis.
Comparative analysis of findings from both model systems.

Main Results:

Fruit flies and zebrafish provide powerful genetic manipulation capabilities for studying cancer initiation and progression.
These models facilitate the investigation of the tumor microenvironment's role in metastasis and drug resistance.
The affordability and rapid life cycles of these organisms accelerate the pace of discovery.

Conclusions:

Fruit flies and zebrafish are invaluable model organisms for advancing fundamental cancer research.
These models can significantly contribute to the identification and validation of novel therapeutic strategies for cancer.
