Insights

Activating transcription factor 2 (ATF2) is crucial in skin tumor development. Its altered signaling impacts cell survival and DNA repair, contributing to both malignant and non-malignant skin conditions.

Area of Science:

  • Molecular Biology
  • Dermatology
  • Oncology

Background:

  • Signal transduction pathways regulate critical cellular processes like survival and death.
  • Alterations in these pathways are observed during skin tumor development and progression.
  • The activating transcription factor 2 (ATF2) is implicated in skin tumorigenesis.

Purpose of the Study:

  • To summarize the current understanding of ATF2 regulation and function.
  • To elucidate ATF2's contribution to malignant and non-malignant skin tumor development.

Main Methods:

  • Review of existing literature on ATF2 signaling.
  • Analysis of ATF2's role in cellular processes relevant to skin cancer.
  • Examination of ATF2 phosphorylation by JNK/p38 and ATM/ATR kinases.

Main Results:

  • ATF2 phosphorylation by JNK/p38 or ATM/ATR influences its activity.
  • Changes in ATF2 signaling impact downstream targets involved in cell fate.
  • ATF2 plays a role in both the development and progression of skin tumors.

Conclusions:

  • ATF2 is a key mediator in skin tumor development.
  • Understanding ATF2 regulation and function is vital for targeting skin cancer.
  • Further research into ATF2 signaling pathways may reveal therapeutic strategies.

DNA Damage can Stall the Cell Cycle02:36

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...

Translesion DNA Polymerases

Translesion (TLS) polymerases rescue stalled DNA polymerases at sites of damaged bases by replacing the replicative polymerase and installing a nucleotide across the damaged site. Doing so, TLS allows additional time for the cell to repair the damage before resuming regular DNA replication.
TLS polymerases are found in all three domains of life - archaea, bacteria, and eukaryotes. Of the different classes of TLS polymerases, members of the Y family are fitted with specialized structures that...

Fixing Double-strand Breaks

The double-stranded structure of DNA has two major advantages. First, it serves as a safe repository of genetic information where one strand serves as the back-up in case the other strand is damaged. Second, the double-helical structure can be wrapped around proteins called histones to form nucleosomes, which can then be tightly wound to form chromosomes. This way, DNA chains up to 2 inches long can be contained within microscopic structures in a cell. A double-stranded break not only damages...

DNA Distortion and Damage
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
