Targeted Cancer Therapies02:57

Targeted Cancer Therapies

7.5K
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...

Electron Transport Chain: Complex I and II01:46

Electron Transport Chain: Complex I and II

12.0K
The mitochondrial electron transport chain (ETC) is the main energy generation system in the eukaryotic cells. However, mitochondria also produce cytotoxic reactive oxygen species (ROS) due to the large electron flow during oxidative phosphorylation. While Complex I is one of the primary sources of superoxide radicals, ROS production by Complex II is uncommon and may only be observed in cancer cells with mutated complexes.
ROS generation is regulated and maintained at moderate levels necessary...

Adaptive Mechanisms in Cancer Cells02:53

Adaptive Mechanisms in Cancer Cells

5.7K
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,...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

3.7K
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...

Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

4.9K
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...

Inhibition of Cdk Activity02:34

Inhibition of Cdk Activity

4.7K
The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

Background:

  • Healthy cells use antioxidants to manage reactive oxygen species (ROS).
  • Cancer cells often have elevated ROS and altered antioxidant levels, including decreased catalase.
  • Catalase detoxifies hydrogen peroxide, crucial for cellular defense against oxidative stress.

Purpose of the Study:

  • To review recent advances in understanding catalase's role in cancer.
  • To update knowledge on catalase expression, localization, and microbial catalase potential in tumors.
  • To discuss catalase-based therapies for cancer treatment.

Main Methods:

  • Literature review of research on catalase and cancer over the last decade.
  • Analysis of catalase's impact on cancer cell proliferation, metabolism, immune escape, and metastasis.
  • Examination of therapeutic strategies involving catalase modulation.

Main Results:

  • Decreased catalase in cancer cells contributes to ROS-driven proliferation and metastasis.
  • Catalase regulates key cancer processes including metabolic reprogramming and immune evasion.
  • Microbial catalases and therapeutic interventions show promise but have limitations.

Conclusions:

  • Catalase plays a complex, multifaceted role in cancer progression and development.
  • Understanding catalase regulation and function is critical for developing novel cancer therapies.
  • Targeting catalase offers potential therapeutic avenues, requiring careful consideration of benefits and drawbacks.
