Summary
This summary is machine-generated.Cancer-associated Schwann cells (CAS) promote lung cancer chemoresistance by creating an adrenergic microenvironment. These cells activate YAP/TAZ, leading to adrenaline production and enhanced cancer cell survival.
Area Of Science
- Oncology
- Neuroscience
- Cell Biology
Background
- Doublecortin (DCX)-positive cells are implicated in the cancer microenvironment and linked to cancer progression.
- The precise mechanisms by which DCX-positive cells influence cancer progression remain largely unexplored.
Purpose Of The Study
- To elucidate the identity and function of DCX-positive cells in lung cancer.
- To investigate the role of these cells in mediating chemoresistance within the lung cancer microenvironment.
Main Methods
- Immunohistochemical analysis of lung cancer tissues to identify and characterize DCX-positive cells.
- Investigation of the Hippo pathway transducer YAP/TAZ activation in these cells.
- Analysis of catecholamine synthesis and adrenergic signaling in the tumor microenvironment.
Main Results
- DCX-positive cells in lung cancer are identified as cancer-associated Schwann cells (CAS).
- CAS establish an adrenergic microenvironment by synthesizing adrenaline, potentiating lung cancer cell chemoresistance.
- Activation of YAP/TAZ is crucial for CAS acquisition of new traits and DCX positivity.
Conclusions
- Cancer-associated Schwann cells (CAS) are key components of the lung cancer microenvironment.
- CAS contribute to chemoresistance through an adrenergic mechanism involving YAP/TAZ activation and adrenaline synthesis.
- Reciprocal regulation of YAP/TAZ in CAS drives the adrenergic microenvironment in lung cancer.

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,...
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...
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...
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...
Cells can detect chemical cues in their environment and reorganize the cytoskeleton to migrate toward them or away from them. This directional migration, called chemotaxis, is essential during embryogenesis and development, immune response, tissue repair and regeneration, and reproduction. These chemical cues can either attract or repel the cell's movement. For example, axon development is determined by a combination of chemoattractants and chemorepellents that direct the growing axon...
