Insights

Targeted therapies targeting MET alterations, including MET exon 14 skipping, have transformed non-small cell lung cancer (NSCLC) treatment. This review covers MET pathway history, pathophysiology, and evolving therapeutic strategies for NSCLC patients.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • The MET pathway, identified in 1984, plays a crucial role in cell survival and migration.
  • Genomic alterations in MET, such as MET exon 14 (METex14) skipping, mutations, and amplification, occur in 3%-5% of non-small cell lung cancer (NSCLC) patients.
  • These alterations lead to sustained MET receptor activation, driving tumor progression.

Purpose of the Study:

  • To review the history and pathophysiology of the MET pathway, with a focus on METex14 skipping in NSCLC.
  • To examine the evolution of diagnostic and therapeutic strategies for MET-altered NSCLC.
  • To discuss current treatments and future directions for overcoming resistance mechanisms.

Main Methods:

  • Literature review of the MET pathway, METex14 skipping, and targeted therapies in NSCLC.
  • Analysis of historical and recent research on MET alterations and their clinical implications.
  • Examination of treatment outcomes and resistance patterns associated with MET-targeted agents.

Main Results:

  • MET alterations represent a significant driver in a subset of NSCLC patients.
  • The development of next-generation sequencing has enabled the identification of these alterations.
  • Targeted therapies have shown efficacy in patients with specific MET alterations, altering the treatment landscape.

Conclusions:

  • METex14 skipping and other MET alterations are actionable targets in NSCLC.
  • Advances in understanding the MET pathway have led to novel therapeutic options.
  • Future research should focus on addressing resistance mechanisms to further improve patient outcomes.

Metastasis02:30

Metastasis

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

ER Retrieval Pathway01:45

ER Retrieval Pathway

In the secretory pathway, vesicles transport proteins from one cellular compartment to another in forward transport to deliver the protein to its correct location. Occasionally, misfolded proteins and incorrect proteins escape their original compartments, and a retrieval pathway is used to return the escaped proteins to their original compartment.
The ER uses many checkpoints to prevent the entry of incorrectly folded or a resident protein as cargo onto a transport vesicle. These mechanisms...

Translocation of Proteins into the Mitochondria01:19

Translocation of Proteins into the Mitochondria

Mitochondrial precursors are translocated to the internal subcompartments via independent mechanisms involving distinct protein machineries called translocases.
Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...

Long-patch Base Excision Repair

Since the discovery of the two BER pathways, there has been a debate about how a cell chooses one pathway over the other and the factors determining this selection. Numerous in vitro experiments have pointed out multiple determinants for the sub-pathway selection. These are:

Mitochondrial Precursor Proteins01:39

Mitochondrial Precursor Proteins

Mitochondrial precursors are partially unfolded or loosely folded polypeptide chains. Newly synthesized precursors are inhibited from spontaneously folding into their native conformation by the cytosolic chaperones, heat shock proteins 70 (Hsp70), and mitochondrial import stimulation factors (MSFs). Precursors bound to MSFs are guided to the TOM70-TOM37 receptors, while precursors bound to Hsp70  chaperones are targetted to TOM20-TOM22 receptor complexes.
Most of the mitochondrial...

Loss of Tumor Suppressor Gene Functions01:12

Loss of Tumor Suppressor Gene Functions

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
