Targeted Cancer Therapies02:57

Targeted Cancer Therapies

9.0K
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...

Cancer-Critical Genes I: Proto-oncogenes

11.6K
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

Cancer

55.0K
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.

Tumor Immunotherapy01:27

Tumor Immunotherapy

2.1K
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

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...

Area of Science:

  • Developmental biology
  • Cancer biology
  • Oncology

Background:

  • Cancer shares histological similarities with embryonic tissues.
  • Evidence indicates cancer hijacks developmental processes for tumor growth.
  • Key developmental programs are implicated in both normal development and cancer.

Purpose of the Study:

  • To review how disruptions in developmental pathways drive cancer progression.
  • To highlight developmental pathways as targets for novel cancer therapies.

Main Methods:

  • Literature review of developmental biology and cancer research.
  • Analysis of shared molecular and cellular mechanisms.
  • Focus on lineage commitment, cell motility/invasion, and microenvironmental influences.

Main Results:

  • Cancer progression involves co-opting embryonic processes like stem cell lineage commitment.
  • Aberrant cell motility and invasion mechanisms, crucial in development, are reactivated in cancer.
  • The tumor microenvironment recapitulates aspects of developmental niches, influencing cancer.

Conclusions:

  • Derangements in developmental pathways are fundamental to cancer progression.
  • Targeting these reactivated developmental programs offers promising novel therapeutic strategies for cancer treatment.
