Summary
Vocal fold polyps show significantly higher apoptosis rates compared to healthy tissue. Targeting apoptosis pathways may offer new therapeutic strategies for vocal fold polyp treatment.
Area of Science:
- Cell Biology
- Pathology
- Otolaryngology
Background:
- Vocal fold polyps are benign growths affecting voice quality.
- The underlying mechanisms of polyp formation are not fully understood.
- Apoptosis, or programmed cell death, plays a role in tissue homeostasis.
Purpose of the Study:
- To investigate the extent of apoptosis in vocal fold polyps.
- To elucidate the role of apoptosis in the pathogenesis of vocal fold polyps.
Main Methods:
- A retrospective review of 61 vocal fold polyps and 41 control vocal folds.
- Microscopic analysis included apoptosis, mitosis, inflammation, and exocytosis.
- Apoptotic index was quantified per square millimeter of epithelium.
Main Results:
- Vocal fold polyps exhibited a statistically significant higher apoptotic index compared to controls.
- Increased apoptosis in polyps correlated with higher mitotic index, inflammation, and exocytosis.
- These parameters were significantly elevated in polyps versus the control group.
Conclusions:
- Apoptosis is significantly increased in vocal fold polyps.
- Modulating apoptosis pathways presents a potential therapeutic avenue for vocal fold polyps.
- Targeting specific apoptotic cells could offer a precise treatment strategy without harming healthy tissue.

01:30Apoptosis
16.2K
Apoptosis is a combination of two Greek words, 'apo' and 'ptosis,' meaning separation and falling off, respectively. Hippocrates used this word to describe gangrene, which was caused due to bandaging of fractured bones. Apoptosis was distinguished from necrosis in 1970 when John Kerr reported observations of morphological changes occurring during apoptosis. During one experiment, he observed that the disruption of blood supply to the liver tissue resulted in a size...

01:21Larynx
5.4K
The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...

01:17Phagocytosis of Apoptotic Cells
5.4K
Cells undergoing apoptosis form apoptotic bodies that must be removed immediately to prevent inflammation, autoimmune diseases, and necrosis. Phagocytosis is carried out by professional phagocytes such as macrophages or immature dendritic cells. Non-professional phagocytes such as epithelial cells and fibroblasts also take part in this process; however, they are not as effective as professional phagocytes.

01:17The Extrinsic Apoptotic Pathway
9.1K
The extrinsic apoptotic pathway is initiated when extracellular death-inducing signals, such as specific cytokines, activate the death receptors expressed on the cell surface. The immune cells involved in this pathway are natural killer cells (NK cells) and cytotoxic T-lymphocytes. NK cells are critical in innate immune response, while cytotoxic T-lymphocytes are associated with adaptive immune response. These cells recognize specific receptors expressed on the altered cells and activate...

02:23Abnormal Proliferation
5.3K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

01:12Loss of Tumor Suppressor Gene Functions
6.2K
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...
