Summary
Yeasts serve as a valuable model for studying programmed cell death (PCD) pathways, aiding in the development of novel anticancer and antifungal drugs by examining drug-induced apoptosis.
Area of Science:
- * Molecular Biology and Pharmacology
- * Cellular Biology and Drug Discovery
Background:
- * Drug development is a critical research area focused on combating diseases like cancer and infections.
- * Programmed cell death (PCD) modulation is a key mechanism in designing effective anticancer and antifungal drugs.
- * Yeasts offer a conserved cellular machinery for studying PCD pathways relevant to higher eukaryotes.
Purpose of the Study:
- * To explore the utility of yeast as a model organism for studying drug-induced apoptosis.
- * To investigate the mechanisms of drug action on PCD pathways in yeast.
- * To assess the potential of yeast-based models for developing targeted anticancer and antifungal therapies.
Main Methods:
- * Review of existing literature on drug-induced apoptosis in yeast.
- * Analysis of conserved PCD pathways between yeast and mammalian cells.
- * Examination of reactive oxygen species (ROS) generation and mitochondrial function alterations.
Main Results:
- * Anticancer drugs induce apoptosis in yeast via ROS generation and altered mitochondrial functions, similar to mammalian cells.
- * Yeast models demonstrate conserved mechanisms of drug-induced apoptosis.
- * Fungal-specific apoptotic regulators can be targeted for antifungal drug development.
Conclusions:
- * Yeast is a powerful model for screening and developing PCD-directed drugs.
- * Yeast models can help overcome cellular specificity issues in anticancer drug design.
- * Targeting fungal-specific apoptotic pathways in yeast can lead to effective antifungal drugs with minimal impact on human cells.

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...
01:30Apoptosis
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...
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...
01:28Yeast Signaling
Yeasts are single-celled organisms, but unlike bacteria, they are eukaryotes (cells with a nucleus). Cell signaling in yeast is similar to signaling in other eukaryotic cells. A ligand, such as a protein or a small molecule released from a yeast cell, attaches to a receptor on the cell surface. The binding stimulates second-messenger kinases to activate or inactivate transcription factors that further regulate gene expression. Many of the yeast intracellular signaling cascades have similar...
01:18Autophagic Cell Death
Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.
