DNA Damage can Stall the Cell Cycle

DNA Damage can Stall the Cell Cycle

In response to DNA damage, cells can pause the cell cycle to assess and repair the breaks. However, the cell must check the DNA at certain critical stages during the cell cycle. If the cell cycle pauses before DNA replication, the cells will contain twice the amount of DNA. On the other hand, if cells arrest after DNA replication but before mitosis, they will contain four times the normal amount of DNA. With a host of specialized proteins at their disposal,cells must use the right protein at...

Replicative Cell Senescence

Replicative Cell Senescence

Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds...

The Extrinsic Apoptotic Pathway

The 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...

Area of Science:

Molecular Biology
Cancer Biology
Genetics

Background:

Dicer is essential for microRNA (miRNA) processing.
The precise cellular requirements for Dicer function are not fully understood.
The role of Dicer in tumorigenesis requires further investigation.

Purpose of the Study:

To review the cellular consequences of Dicer loss in various cell types.
To investigate the impact of Dicer alteration on tumorigenesis.
To determine if p53 loss influences cell survival and proliferation in the absence of Dicer.

Main Methods:

Literature review of studies on Dicer function and loss.
Analysis of Dicer's role in different cellular contexts.
Examination of the interplay between Dicer and p53 pathways.

Main Results:

Dicer loss has varied effects depending on cell type and origin.
Altered Dicer levels can promote or inhibit tumorigenesis.
p53 status influences the ability of cells to survive and grow without Dicer.

Conclusions:

Dicer's cellular requirements are complex and context-dependent.
Dicer is a critical factor in cancer development.
The p53 pathway plays a significant role in Dicer-deficient cell viability.
