Tumor Progression02:07

Tumor Progression

7.5K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

4.9K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

In Vitro Drug Dissolution: Compendial Testing Models I01:13

In Vitro Drug Dissolution: Compendial Testing Models I

310
Compendial dissolution methods are standardized procedures defined by pharmacopeias to evaluate the rate at which a drug dissolves in a specific medium. These methods ensure batch-to-batch consistency, enable quality control, and support the prediction of drug bioavailability. They are critical for both immediate and modified-release drug products.The apparatuses used for dissolution testing differ in their design and mechanical function, but all aim to simulate the physiological environment of...

In Vitro Drug Dissolution: Compendial Testing Models II

338
Various dissolution methods are utilized to assess a drug’s dissolution rate, including the flow-through cell, paddle-over-disk, cylinder, and reciprocating disk methods.The flow-through cell apparatus (USP (United States Pharmacopeia) method 4) comprises a reservoir for the dissolution medium and a pump that propels the medium through the cell containing the test sample. This method is crucial for assessing modified-release dosage forms with minimally soluble active ingredients,...

In-vitro Mutagenesis

16.6K
To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.

In Vitro Fertilization01:24

In Vitro Fertilization

1.0K
In vitro fertilization (IVF) is a form of assisted reproductive technology where an egg is fertilized with sperm in a controlled laboratory environment before transferring the resulting embryo into the uterus. This process is designed to help individuals and couples experiencing difficulties conceiving.
The IVF process begins with ovarian stimulation, during which reproductive endocrinologists prescribe hormonal medications to stimulate the ovaries to produce multiple eggs instead of the single...

Area of Science:

  • Oncology
  • Biotechnology
  • In vitro modeling

Background:

  • Melanoma research faces challenges with current laboratory techniques and animal models due to physiological differences.
  • Existing adherent cell cultures do not accurately reflect melanoma's in vivo 3D growth and microenvironment.
  • International guidelines promote the 3Rs (Reduction, Refinement, Replacement) for animal experimentation.

Purpose of the Study:

  • To review advanced 3D in vitro models for studying melanoma.
  • To highlight new technologies that improve the accuracy of melanoma research models.
  • To discuss the potential of these models in reducing and replacing animal testing.

Main Methods:

  • Review of literature on 3D in vitro melanoma models.
  • Description of techniques like spherical models, tumorospheres, and melanoma skin equivalents.
  • Inclusion of emerging technologies such as organ-on-a-chip systems.

Main Results:

  • 3D models provide a microenvironment closer to in vivo conditions, capturing cell-cell and cell-matrix interactions.
  • These models are more cost-effective and less time-consuming than traditional animal studies.
  • New technologies like organ-on-a-chip enhance the sophistication and relevance of in vitro skin models.

Conclusions:

  • 3D in vitro models are increasingly sophisticated and representative of the in vivo melanoma situation.
  • These advanced models offer a promising alternative to animal testing, aligning with the 3Rs.
  • While significant progress has been made, a 'perfect' model for complete animal replacement is still under development.
