mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

4.8K
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...

Tumor Progression02:07

Tumor Progression

7.4K
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...

Mouse Models of Cancer Study

6.6K
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,...

In Vitro Drug Dissolution: Compendial Testing Models I01:13

In Vitro Drug Dissolution: Compendial Testing Models I

276
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

320
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,...

Cancer

54.3K
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.

Area of Science:

  • Oncology
  • Cell Biology
  • Genetics

Background:

  • Prostate cancer (CaP) development mechanisms are poorly understood.
  • Existing experimental models have limitations in studying CaP progression.
  • Previous work established hormonal progression of BPH1 cells into malignant cells.

Purpose of the Study:

  • To develop a novel human cell line model for studying CaP progression.
  • To create a model that parallels cellular, genetic, and epigenetic changes in human CaP patients.
  • To provide a tool for discovering and validating CaP development mechanisms.

Main Methods:

  • Derivation of human cell lines from distinct stages of CaP.
  • Utilizing diverse analytical strategies to characterize the cell model.
  • Comparative analysis with human and transgenic mouse CaP data.

Main Results:

  • The BPH1-derived Cancer Progression (BCaP) model represents distinct stages of cancer.
  • BCaP model reproduces molecular characteristics of CaP observed in patients.
  • BCaP cells exhibit altered gene expression and increasing genomic instability, including TMPRSS2-ERG fusion in advanced cells.

Conclusions:

  • The BCaP cell lines offer a unique model for human CaP progression.
  • This model facilitates the discovery and experimental validation of CaP regulatory mechanisms.
  • BCaP provides a valuable tool for advancing prostate cancer research.
