Background:

  • SWI/SNF chromatin remodeling complexes are crucial epigenetic regulators.
  • Alterations in SWI/SNF components are frequently observed in human cancers, contributing to tumorigenesis.
  • Understanding the oncogenic roles of SWI/SNF complexes is vital for developing targeted therapies.

Purpose of the Study:

  • To integrate large-scale cancer genomic data to understand tumorigenesis driven by SWI/SNF subunit alterations.
  • To evaluate therapeutic strategies targeting vulnerabilities in SWI/SNF-mutant cancers.
  • To provide an overview of current and emerging treatments for SWI/SNF-altered cancers.

Main Methods:

  • Integration of large-scale cancer genomic datasets.
  • Analysis of SWI/SNF complex subunit alterations across various cancer types.
  • Review of preclinical and clinical data on therapeutic strategies.

Main Results:

  • SWI/SNF alterations are common drivers of tumorigenesis through diverse mechanisms.
  • Targeting residual SWI/SNF components and unique cellular dependencies shows promise.

Targeted Cancer Therapies02:57

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...

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,...

Combination Therapies and Personalized Medicine02:50

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...

Cancer Therapies

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Treatment Resistant Cancers02:56

Treatment Resistant Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
