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.

Adaptive Mechanisms in Cancer Cells

Adaptive Mechanisms in Cancer Cells

Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

Targeted Cancer Therapies

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against specific...

Combination Therapies and Personalized Medicine

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Area of Science:

Synthetic biology
Molecular oncology
Biotechnology

Background:

Traditional cancer therapies often target single genes, limiting efficacy against complex cancer signaling networks.
Precision oncology requires sophisticated tools to differentiate cancer cells from healthy tissues.
Bladder cancer (BC) presents challenges due to intricate and heterogeneous signaling pathways.

Purpose of the Study:

To engineer a synthetic gene circuit for precise targeting and reprogramming of bladder cancer (BC) cells.
To overcome limitations of single-target approaches in cancer therapy.
To develop a novel therapeutic strategy leveraging synthetic biology for BC.

Main Methods:

Bioinformatics analysis to identify unique, co-expressed BC biomarkers.
Design and synthesis of a Logic "AND" Gate Dual-Target Genetic Circuit (LAG-DTGC).
Engineering the circuit for selective activation based on multiple aberrant cancer-specific biomarkers.

Main Results:

The LAG-DTGC selectively activates in BC cells expressing specific aberrant biomarkers.
The circuit effectively reprograms cancer cell signaling pathways, utilizing cellular mechanisms against the cancer.
Demonstrated precision and capability to remodel cancer cell behavior.

Conclusions:

The LAG-DTGC represents a significant advancement in precision oncology for bladder cancer.
Synthetic biology offers a promising platform for developing targeted and less toxic cancer therapies.
This dual-target circuit approach holds potential for a new paradigm in cancer treatment.
