Summary
UVB irradiation did not induce apoptosis in Saccharomyces cerevisiae. Further research is needed to develop effective UV-radiation protocols for triggering apoptosis in this yeast species.
Area of Science:
- Mycology
- Molecular Biology
- Photobiology
Background:
- Saccharomyces cerevisiae can cause invasive nosocomial fungal infections.
- Understanding yeast apoptosis is crucial for developing targeted antifungal therapies.
Purpose of the Study:
- To evaluate the effectiveness of UVB irradiation in inducing apoptosis in Saccharomyces cerevisiae.
- To investigate the potential of photobiology in controlling pathogenic yeast.
Main Methods:
- Yeast colonies of Saccharomyces cerevisiae were exposed to UVB light (302 nm) for 10 minutes.
- DNA from control and irradiated samples was analyzed using agarose gel electrophoresis.
- Ethidium bromide was used as a luminescent dye to visualize DNA.
Main Results:
- UVB irradiation did not result in observable DNA laddering or smears.
- The applied UVB exposure protocol was ineffective in inducing apoptotic changes.
Conclusions:
- The current UVB-radiation protocol is insufficient to trigger apoptosis in Saccharomyces cerevisiae.
- New protocols are required to induce apoptosis in this yeast for potential therapeutic applications.

01:31The Intrinsic Apoptotic Pathway
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...
01:35Mutations
Mutations are changes in the sequence of DNA. These changes can occur spontaneously or they can be induced by exposure to environmental factors. Mutations can be characterized in a number of different ways: whether and how they alter the amino acid sequence of the protein, whether they occur over a small or large area of DNA, and whether they occur in somatic cells or germline cells.

01:22Cellular Injury V: Apoptosis and Autophagy
Cells respond to damage and stress through highly coordinated processes that decide whether they survive or undergo controlled self-destruction. Two major pathways involved in this regulation are apoptosis, a type of programmed cell death, and autophagy, a survival mechanism that helps cells adapt to adverse conditions.ApoptosisApoptosis removes aged or injured cells to maintain tissue balance. During this process, the cell shrinks, chromatin condenses and fragments, and membrane-bound...
01:30Apoptosis
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 reduction of the tissue.
01:17The Extrinsic Apoptotic Pathway
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...
