Summary
The mouse TARSH gene induces p53-dependent apoptosis, suggesting its role in preventing cancer. Suppressing TARSH may offer a new therapeutic strategy for lung carcinoma.
Area of Science:
- Molecular Biology
- Cancer Research
- Cellular Biology
Background:
- The target of NESH-SH3/Abi3bp (TARSH) protein binds to NESH-SH3/Abi3, influencing actin polymerization.
- TARSH gene expression is elevated during cellular senescence but reduced in lung and thyroid carcinomas.
Purpose of the Study:
- To investigate the molecular mechanism of TARSH regulation in tumorigenesis.
- To explore the p53-dependent apoptosis function of the mouse TARSH gene.
Main Methods:
- RNA interference (RNAi) was used to suppress endogenous TARSH expression in mouse cells.
- Analysis of p53-dependent apoptosis was performed following TARSH suppression.
Main Results:
- Suppression of TARSH expression was achieved using RNAi.
- The study identified a p53-dependent apoptosis function associated with the mouse TARSH gene.
Conclusions:
- The findings reveal a novel role for TARSH in p53-dependent apoptosis.
- TARSH may serve as a potential therapeutic target for lung carcinoma treatment.

02:23Abnormal Proliferation
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 daughter...
01:12Loss of Tumor Suppressor Gene Functions
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...

01:05Cancer-Critical Genes II: Tumor Suppressor Genes
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

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...
