Insights

RNA interference (RNAi) helps identify cancer drug resistance mechanisms. Targeting the anti-apoptotic protein cellular FLICE-like inhibitory protein (c-FLIP) shows promise for overcoming cancer resistance.

Area of Science:

  • Molecular Biology
  • Cancer Research
  • Drug Development

Background:

  • Gene silencing via RNA interference (RNAi) has elucidated key proteins implicated in cancer drug resistance.
  • Cancer resistance is frequently linked to dysfunctions within apoptotic signaling pathways.

Purpose of the Study:

  • To investigate the potential of RNAi as a strategy for targeting the anti-apoptotic protein cellular FLICE-like inhibitory protein (c-FLIP).
  • To explore the therapeutic implications of targeting c-FLIP in the context of overcoming cancer chemotherapy resistance.

Main Methods:

  • Utilizing RNA interference (RNAi) technology to specifically silence gene expression.
  • Focusing on the anti-apoptotic protein cellular FLICE-like inhibitory protein (c-FLIP).

Main Results:

  • Identification of proteins contributing to cancer drug resistance through RNAi screening.
  • Association of resistance mechanisms with defects in apoptotic signaling pathways.

Conclusions:

  • Targeting c-FLIP using RNAi presents a potential therapeutic avenue for enhancing chemotherapy efficacy.
  • Further drug development efforts should consider c-FLIP as a target to combat cancer resistance.

The Intrinsic Apoptotic Pathway01:31

The Intrinsic Apoptotic Pathway

Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...
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 specific...
The Extrinsic Apoptotic Pathway01:17

The Extrinsic Apoptotic Pathway

The extrinsic apoptotic pathway is initiated when extracellular death-inducing signals, such as specific cytokines, activate the death receptors expressed on the cell surface. The immune cells involved in this pathway are natural killer cells (NK cells) and cytotoxic T-lymphocytes. NK cells are critical in innate immune response, while cytotoxic T-lymphocytes are associated with adaptive immune response. These cells recognize specific receptors expressed on the altered cells and activate...
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...
Phagocytosis of Apoptotic Cells01:17

Phagocytosis of Apoptotic Cells

Cells undergoing apoptosis form apoptotic bodies that must be removed immediately to prevent inflammation, autoimmune diseases, and necrosis. Phagocytosis is carried out by professional phagocytes such as macrophages or  immature dendritic cells. Non-professional phagocytes such as  epithelial cells and fibroblasts also take part in this process; however, they are not as effective as professional phagocytes. 
Normal cells contain receptors that prevent them from being recognized by phagocytes.
Inhibition of Cdk Activity02:34

Inhibition of Cdk Activity

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...
