Insights

Acquired drug resistance in cancer hinders treatment effectiveness. RNA interference (RNAi) helps identify drug resistance pathways, aiming to improve cancer therapy outcomes and patient survival.

Area of Science:

  • Oncology
  • Genetics
  • Molecular Biology

Background:

  • Acquired drug resistance diminishes the effectiveness of cytotoxic therapies in both hematological and solid tumors.
  • Treatment failure significantly impacts patient quality of life and survival in advanced and metastatic cancers.
  • Understanding drug resistance mechanisms is crucial for developing strategies to prolong treatment efficacy and delay disease progression.

Purpose of the Study:

  • To define pathways of intrinsic and acquired drug resistance.
  • To identify novel therapeutic targets for overcoming drug resistance.
  • To establish methods for predicting intrinsic drug sensitivity in human tumors prior to cytotoxic therapy.

Main Methods:

  • Utilizing RNA interference (RNAi) for gene function annotation.
  • Employing high-throughput screening RNAi technology to systematically define drug-resistance pathways.
  • Investigating the integration of RNAi screening data with biological samples.

Main Results:

  • RNAi screening has identified drug-specific resistance pathways.
  • Novel pathways contributing to multidrug sensitivity have been discovered.
  • Evidence suggests the potential to define in vivo drug-resistant pathways.

Conclusions:

  • Defining drug resistance pathways is essential for improving cancer treatment outcomes.
  • RNA interference is a valuable tool for dissecting complex drug resistance mechanisms.
  • Further research is needed to integrate in vitro findings with in vivo biological systems to translate discoveries into clinical applications.

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...
Experimental RNAi02:15

Experimental RNAi

RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...
mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

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...
Protein Networks02:26

Protein Networks

An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

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,...
