Summary
Odorant receptors (ORs) are found in non-olfactory tissues and are linked to cancer. Analyzing cancer patient data suggests ORs could serve as cancer biomarkers and therapeutic targets.
Area of Science:
- Biochemistry
- Oncology
- Genomics
Background:
- Odorant receptors (ORs), primarily known for olfaction, are expressed in various non-olfactory tissues.
- Expression of ORs in tumor cells suggests potential roles in cancer progression and as biomarkers.
- This review explores the association of ORs with cancer signaling and clinical relevance.
Approach:
- Analyzed OR expression in diverse cancers using RNA-sequencing data from The Cancer Genome Atlas.
- Visualized OR expression patterns in cancer using t-distributed stochastic neighbor embedding (t-SNE).
- Assessed the correlation between OR expression levels and patient survival data.
Key Points:
- ORs are expressed in numerous cancer types, implicating them in cancer biology.
- Specific OR expression patterns correlate with different cancer signaling pathways.
- Analysis of mRNA data reveals significant associations between OR levels and patient outcomes.
Conclusions:
- Odorant receptors represent potential biomarkers for cancer detection and prognosis.
- ORs may serve as novel therapeutic targets for cancer treatment.
- Further research into OR function in cancer is warranted for clinical applications.

01:03Olfactory Receptors: Location and Structure
9.8K
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...

01:21Chemotaxis and Direction of Cell Migration
3.7K
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...

01:25Olfaction
45.6K
The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.

01:20Physiology of Smell and Olfactory Pathway
9.9K
Humans detect odors with the help of specialized cells located in the upper part of the nasal cavity, called olfactory receptor neurons (ORNs). ORNs possess hair-like structures called cilia, which are receptive to sensations from the inhaled air. When an odorant molecule binds to a specific receptor on the cell of the cilia, it leads to a series of events that ultimately cause the ORN to send electrical signals to the olfactory bulb in the brain through the olfactory nerves.

01:27Tactile and Chemical Senses
384
Tactile senses encompass touch, temperature, and pain, each mediated by specific receptors. Touch receptors detect mechanical energy or pressure against the skin. Sensory fibers from these receptors enter the spinal cord and relay information to the brain stem. Here, most fibers cross over to the opposite side of the brain. The touch information then moves to the thalamus, which projects a map of the body's surface onto the somatosensory areas of the parietal lobes in the cerebral cortex.

02:38Mitogens and the Cell Cycle
7.0K
Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
