Summary
Survivin is commonly found in canine lymphomas and appears to regulate cell cycle rather than apoptosis. Further research is needed to understand its precise role in canine lymphoma progression.
Area of Science:
- Veterinary Oncology
- Molecular Biology
- Cancer Research
Background:
- Survivin is a protein regulating cell division and apoptosis, crucial in human cancers.
- Its role in canine lymphomas is largely unstudied.
- Understanding survivin's function is key to developing targeted therapies.
Purpose of the Study:
- To investigate survivin expression in canine lymphomas.
- To correlate survivin levels with tumor grade and apoptotic markers.
- To determine survivin's potential anti-apoptotic role in canine lymphoma.
Main Methods:
- Immunohistochemical analysis of survivin expression.
- Assessment of apoptotic index and caspase-3 index in canine lymphoma samples.
- Comparison of survivin and apoptotic markers between low and high-grade lymphomas.
Main Results:
- Survivin was expressed in all canine lymphomas analyzed.
- No significant difference in survivin or apoptotic index between low and high-grade lymphomas.
- Caspase-3 index differed significantly between lymphoma grades.
- No correlation found between survivin and apoptotic markers.
Conclusions:
- Survivin is frequently expressed in canine lymphomas.
- Survivin may not exert anti-apoptotic effects in canine lymphomas.
- Survivin's role might be linked to cell cycle regulation in canine lymphoma.

01:31The Intrinsic Apoptotic Pathway
8.8K
Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...

15.7K
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...

01:17The Extrinsic Apoptotic Pathway
9.0K
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...

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...

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...
