Insights

Identifying reliable biomarkers for non-small-cell lung cancer (NSCLC) treatment is crucial. This review examines excision repair cross-complementing 1 (ERCC1) and ribonucleotide reductase M1 (RRM1) expression as predictive markers for platinum-based chemotherapy in NSCLC.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cancer Biomarkers

Background:

  • Platinum compounds are a primary treatment for non-small-cell lung cancer (NSCLC), targeting cancer cell DNA.
  • Excision repair cross-complementing 1 (ERCC1) and ribonucleotide reductase M1 (RRM1) are explored as markers of DNA repair capacity.
  • Existing studies on ERCC1 and RRM1 expression show inconsistent associations with platinum sensitivity.

Purpose of the Study:

  • To review the function and assessment methods of ERCC1 and RRM1 as biomarkers in NSCLC.
  • To summarize the prognostic and predictive value of ERCC1 and RRM1 for platinum-based therapy.
  • To discuss the current limitations and future directions for biomarker discovery in NSCLC.

Main Methods:

  • Literature review of studies investigating ERCC1 and RRM1 expression in NSCLC.
  • Analysis of methodologies used for assessing ERCC1 and RRM1 levels.
  • Synthesis of data on the prognostic and predictive significance of these biomarkers.

Main Results:

  • Low ERCC1 and RRM1 expression generally correlates with platinum sensitivity, but results vary across studies.
  • Technical issues in biomarker assessment contribute to inconsistent findings.
  • The prognostic and predictive roles of ERCC1 and RRM1 require further validation.

Conclusions:

  • ERCC1 and RRM1 show potential as predictive biomarkers for platinum chemotherapy in NSCLC.
  • Current inconsistencies suggest restricting their use to clinical research.
  • Functional assays for DNA repair capacity may offer improved strategies for biomarker development.

Regulation of the Unfolded Protein Response01:31

Regulation of the Unfolded Protein Response

Inositol-requiring kinase one or IRE1 is the most conserved eukaryotic unfolded protein response (UPR) receptor. It is a type I transmembrane protein kinase receptor with a distinctive site-specific RNase activity. As the binding mechanics of the misfolded proteins with the N-terminal domain of IRE-1 are unclear, three binding models — direct, indirect, and allosteric -- are proposed for receptor activation. Nevertheless, it is known that once a misfolded protein associates with IRE1, it...
Directing Proteins to the Rough Endoplasmic Reticulum01:34

Directing Proteins to the Rough Endoplasmic Reticulum

The organelle-specific signaling sequences direct proteins synthesized in the cytosol to their final destination like ER, mitochondria, peroxisomes, etc. Some of the proteins directed to ER are then trafficked via vesicles to other organelles within the cell or the extracellular environment through the Golgi complex. For example, the rough ER synthesizes soluble proteins for transportation to the lysosomes or secretion out of the cell. It can also synthesize transmembrane proteins that can...
RACE - Rapid Amplification of cDNA Ends02:35

RACE - Rapid Amplification of cDNA Ends

Rapid Amplification of cDNA Ends, or RACE, is one of the most effective methods to obtain a full-length cDNA from an mRNA sequence between a known internal region to the unknown sequence at the 5’ or 3’ end. The unknown region is cloned in the cDNA by a gene-specific primer that binds the known end, and a hybrid primer that attaches a predefined anchor sequence to the unknown end of the cDNA. The sequence in between is amplified by PCR with an anchor primer and a gene-specific primer.
Since the...
The Unfolded Protein Response01:37

The Unfolded Protein Response

The ER is the hub of protein synthesis in a cell. It has robust systems to quality control protein folding and also for degradation of terminally misfolded proteins. Under normal conditions, a small proportion of misfolded proteins that cannot be salvaged need to be transported to the cytoplasm by the ER-associated degradation or ERAD pathways. However, if the ERAD cannot handle the misfolded proteins, the cell activates the unfolded protein response or UPR to adjust the protein folding...
Rab Proteins01:14

Rab Proteins

Rab proteins constitute the largest family of monomeric GTPases, of which 70 members are present in humans. Rab proteins and their effectors regulate consecutive stages of vesicle transport such as vesicle transport, docking, and fusion to the correct recipient membrane.
Rab proteins switch between a cytosolic, GDP-bound inactive state and a membrane-anchored, GTP-bound active state. By themselves, Rabs show slow rates of GDP/GTP exchange and GTP hydrolysis. Thus, Rab proteins are considered...
Rous Sarcoma Virus (RSV) and Cancer01:03

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...
